The Best Food Metal Detectors For Nutraceuticals

Food grade metal detection is an importantinspection tool that can be used in the nutraceuticals industryto identify metallic impurities in nutraceuticals. Nutraceuticals are products derived from food sources that offer additional health benefits beyond basic nutritional value. The term “nutraceutical” is a combination of “nutrition” and “pharmaceutical,” coined to describe substances that are not necessarily nutrients (like vitamins and minerals) but may have a beneficial impact on health, prevent chronic diseases, or contribute to the body’s normal functioning. The implementation of nutraceuticals into the food industry can be observed in functional foods, dietary supplements, and health & wellness products.

However, some stages of the manufacturing process can introduce risks of contamination, whether from human mishandling or mechanical faults. A metal detector for food manufacturing can inspect for metal debris concealed within food items, and intercept it before it reaches consumers.

Food grade metal detectors are crucial for safeguarding against both ferrous and non-ferrous metals, such as aluminium and stainless steel. Metal detectors can also serve to protect processing equipment during the production process. Even the smallest metallic particles can cause machinery to malfunction or break-down, leading to costly repairs and operational downtime.

Thankfully, in-line metal detectors can be integrated at various points along the production line and are adaptable to numerous applications. You can browse A&D’s range of food metal detectors here, or scroll down to learn more about how inspection systems can assist your business.

Where Along My Production Line Do I Place My Metal Detectors?

Metal detectors can be integrated at various stages of the production process. It is recommended to conduct product inspections at critical control points or in areas of higher contamination risk, to identify any machinery malfunctions, as well as conducting a final check before the finished product is shipped.

Usually there are three strategic locations for placing metal detectors in a production line:

Start of the Line: Installing a metal detector at the beginning of the line helps protect processing equipment from damage by metal objects such as tags, knife blades, or twist ties. However, relying solely on this initial checkpoint could allow for contamination to occur later in the production process.

End of the Line: Many facilities prefer this placement as a final safeguard before products leave the manufacturing plant and are dispatched to customers. This placement is effective provided the final product is not overly large or dense, which could reduce the metal detector’s sensitivity.

Various Critical Points in the Line: Metal detectors can also be positioned at designated critical control points along the production line to both protect machinery and ensure product safety. The specific locations for these detectors will depend on the plant’s unique operational setup.

What Are the Different Types of Metal Contaminants?

Metals are categorised as either ferrous, nonferrous, or stainless steel. The detectability of these metals depends on their magnetic permeability and electrical conductivity.

  • Ferrous: Ferrous metals, which contain high levels of iron, are both magnetic and conductive. This makes them readily detectable by standard metal detectors.
  • Non-Ferrous: Non-ferrous metals, which do not contain any appreciable amounts of iron, are non-magnetic but are still conductive, which means they can easily be detected with the right correctly installed metal detectors.
  • Stainless Steel: Although it’s considered a ferrous metal, stainless steel is high in chromium. As it’s neither magnetic or conductive, stainless steel can be the hardest of the three metal types to detect, especially if it’s gotten into a product that contains water or if the product has high salt content.

Factors That Lead To False Detections

There are two primary factors that can cause false positives in metal detection: environmental and product-related factors.

Environmental Factors: Metal detectors can sometimes be positioned nearother electromechanical machinery which can significantly increase the likelihood of electromagnetic interference across various frequencies. This interference may disrupt the electromagnetic field of the balanced coils found in single-frequency or multi-frequency metal detectors, resulting in false detections.

Product Factors: Certain product ingredients such as salt, iron, and moisture can affect the detector’s electromagnetic field and potentially trigger false alarms. This issue becomes more pronounced at higher inspection frequencies, which are generally used to identify smaller particles. Consequently, this can lead to substantial product rejections and operational downtime. In the context of nutraceuticals, the probability of false positives is higher due to specialised packaging and the presence of metallic and conductive additives in many supplements.

Measuring Metal Detector Sensitivity in the Food Industry

The spectrum of metal detector sensitivity comes with its own quantifiable metrics. Metal detector sensitivity is commonly measured in millimetres (mm), which indicates the smallest size of a metal sphere that the detector can reliably identify.

In Australia and New Zealand, the Food Standards Australia New Zealand (FSANZ) Code provides the guide for metal detection standards for the food processing industry.

Key Requirements For Metal Detection in the Nutraceuticals & Pharmaceutical Industries

In order to make sure your food grade metal detector is running at an optimal level, make sure you’re adhering to the following core requirements:

  • Regulatory Compliance: Regulatory compliance ensures that metal detection systems meet specific industry standards such as HACCP (Hazard Analysis Critical Control Point) for food safety management and ISO (International Organization for Standardization) for consistent quality across various industries.
  • Sensitivity & Detection Limits:Understand what your detector is capable of consistently identifying in terms of the smallest possible metal contaminant. This is important for eliminating foreign metallic particles from products.
  • Product & Packaging Variability: Consider how different types of products and packaging materials may influence the metal detector’s response and its effectiveness in identifying contaminants.
  • Integration with Production Lines: Take the time and necessary steps needed to correctly integrate your metal detectors into your existing production lines without disrupting workflow or reducing efficiency. Ensure all nearby machinery are not interfering with the electromagnetic fields of the metal detector.
  • Validation & Calibration: This means making regular routine checks and adjustments so as to ensure that metal detectors operate correctly and maintain accuracy over time.
  • Data Logging & Reporting: This involves the systematic recording and analysis of detection data to track performance, identify trends, and maintain compliance with regulatory standards. A lot of modern metal detectors have data capture recording capabilities, so it’s best to discuss this feature with your system supplier prior to purchasing.

Traditional Methods in Food Inspection

Traditional methods such as visual inspection, metal detectors, and manual sorting have long been relied upon in the food processing industry to ensure product safety. Visual inspection involves human operators visually assessing the quality and safety of products, relying on sight and touch. While this method is intuitive, its effectiveness is influenced by human factors, and it may be less consistent compared to automated systems.

Metal detectors are commonly used to identify metallic contaminants in food products. While effective in detecting metal, they can sometimes have limitations in detecting non-metallic contaminants, such as certain plastics or glass. Additionally, metal detectors may not pinpoint the exact location of the contamination, making it challenging to isolate and address the issue effectively.

Manual sorting, where workers manually inspect and remove defective or contaminated items, is another traditional method. This approach heavily relies on the attentiveness and efficiency of human operators. However, this can be labour-intensive, time-consuming, and may not be as precise as automated systems, leading to the possibility of oversight.

Despite their historical significance, these conventional approaches present inherent limitations and potential safety gaps. Human subjectivity and variability in visual inspection, the narrow focus of metal detectors, and the manual labour-intensive nature of sorting processes may compromise the overall effectiveness of these methods. As the food industry evolves, there is a growing need for advanced inspection technologies to address these limitations and enhance the safety and quality assurance processes in food processing. In contrast to these more traditional methods, X-ray food inspection has emerged to offer a more advanced technology to help companies ensure the safety and quality of their food products. Food X-ray inspection systems offer a comprehensive solution by detecting a wide range of contaminants, including metals, plastics, stones, and other foreign materials, irrespective of their composition. These systems provide a level of precision and versatility that surpasses the limitations of visual inspection, metal detectors, and manual sorting. With the ability to identify both metallic and non-metallic contaminants and pinpoint their exact location, X-ray food inspection has become an indispensable tool in modern food processing, providing enhanced safety, regulatory compliance, and consumer confidence in the integrity of the food supply chain.

Ensuring Consumer Safety: How X-Ray Inspection System Enhances Food Quality

Tighter regulations in the realm of food safety serve as a collective benefit, aiming to shield consumers from potential health hazards, uphold the reputations of retail outlets, and prevent manufacturers from distributing contaminated products that could lead to costly repercussions such as lawsuits, recalls, or even operational shutdowns. Distinguishing itself from other screening processes, X-ray inspection stands out as a superior method for identifying physical contaminants; while metal represents a primary source of physical contamination that is easily caught by metal detectors, there is, regrettably, a myriad of other hazards – such as rubber, bone, wood, stone, plastic, and glass – that can find their way into food. As such, the indispensability of X-ray inspection in ensuring food safety is becoming more evident for food manufacturers all over the world. While not every manufacturer may need to invest in sophisticated X-ray technology, ongoing technological advancements in this field ensure that staying at the forefront of food safety remains an attainable goal for those who do.

Key Safety Parameters in Food Inspection

Food safety inspections are conducted to ensure compliance with the food safety standards set by regulatory authorities. A thorough food inspection will typically emcompass;

  • Conducting physical inspections
  • Reviewing records
  • Identifying violations
  • Addressing potential hazards

Some of the key safety parameters that must be noted during a rigorous food inspection include;

Overall Cleanliness and Hygiene: To prevent the spread of harmful microorganisms and avoid contamination and foodborne illnesses, maintaining cleanliness and adhering to proper hygiene practices is of utmost importance.

Storage of Raw and Cooked Ingredients: Uncooked food, including meat, poultry, and raw vegetables, can carry harmful pathogens. To prevent the transfer of pathogens to the general public, it is imperative to keep uncooked ingredients separate from cooked ones.

Thorough Cooking: Thorough cooking stands as one of the pivotal aspects of food safety inspections, and food must be cooked at a required temperature in order to kill harmful microorganisms, particularly when preparing large quantities.

Maintaining Optimum Temperature: Similarly, in order to ensure safety, food must be stored at the correct temperatures in order to prevent the proliferation of harmful microbes.

Correct Implementation of Water: Water, including ice cubes, may harbour harmful chemicals and microorganisms, and as such, it is essential to store and use it properly so as to correctly mitigate potential contamination risks.

A&D product inspection systems inspects every product in the production line, ensuring that both your products and production line operate at the highest possible quality standards.

Why is 100% Product Inspection important?

With rising market standards and consumer expectations, manufacturers and packers must constantly contend with the challenge of improving product consistency without compromising safety standards or competitive pricing. As such, enhancing your brand and boosting ROI go hand in hand. Implementing a 100% product inspection is essential if you want to form a foundation of quality assurance, and to prevent the intrusion of defected and substandard items into the market, which in turn boosts customer satisfaction and builds trust in the brand.

100% product inspection helps your company’s compliance with industry regulations, thereby mitigating the risks of legal issues and ensuring that all products align with safety standards. Early identification and resolution of issues will enhance operational efficiency, contribute to cost savings, and provide a competitive quality advantage in the market.

Additionally, through analysis of the captured inspection data, companies can explore and investigate innovative opportunities in production, which may lead to improvements in your overall supply chain, thus bolstering your overall brand integrity.

Advantages of 100% Product Inspection

The advantage of 100% product inspection is underscored across industries, not only as a crucial aspect of quality control, but also in some cases as a legal necessity, particularly in sectors where meticulous reporting and analysis are imperative for meeting safety standards in Australia.

The incorporation of automated inspection systems into your operations can yield multifaceted benefits for your company, ranging from elevated quality control, error detection and prevention, data capture, increased operational efficiency, streamlined processes, and optimised workforce allocation.

Real-time monitoring of production trends facilitated by data capture enables the swift identification of deviations or adherence to standards, while also ensuring compliance with supermarket protocols that mandate the implementation of comprehensive inspections to meet regulatory requirements.

The 100% product inspection process is advantageous in complying with government and retail regulations whilst elevating quality control, preventing mistakes, increasing production speed and efficiency, improving data capture and analysis, and optimising overall workforce productivity.

Disadvantages of 100% Product Inspection

Ensuring quality protection is paramount through all stages of production from raw ingredients through to finished consumer products. The scrutiny of each product and component during a 100% inspection consumes considerable time, and demands substantial resources. The expenses associated with initiating and sustaining comprehensive inspection practices can be steep, creating hurdles for a number of businesses to rationalise such investments.

The common alternative is to use the process that was ubiquitous before the advent of automated systems – sample testing. With sample testing, manufacturers typically extract 5%-10% of the product from the production line and manually inspect it.

However, this method is extremely labour-intensive, and poses a risk to the company as more than 90% of the product remains uninspected, which may leave your company open to risks and hefty government fines should any of the products fall below safety standards. As such, sample testing is not really a viable foolproof alternative.

Although it is understandable for a new or struggling business to avoid a 100% production inspection due to high investment costs, it is strongly advised that a company implements it whenever feasible. This measure is crucial not only for ensuring compliance with government regulations but also for guaranteeing consumer safety. Our customers have affirmed that the 100% inspection at different production stages not only saves their line employees time and minimises errors, but also results in reduced charge backs, fees, lawsuits, and expensive recalls.

Your Guide To Checkweighers and Checkweighing

What is a checkweigher?

Are you looking for a consistent and reliable way to weigh your products? Checkweighers are automated machines that have been designed to ensure that products are weighed with both efficiency and precision. As such, checkweighers have become common sight additions in modern food manufacturing and packaging lines. Not only can checkweighers reduce the risk of underfill or overfill, but controlled inspection can also flag any quality and safety issues. Delivering consistent quality products is essential to protect your brand and your bottom line, and modern checkweighers have become a valuable investment for companies looking to improve their manufacturing and packaging operations.

There are different types of checkweighers, and while all of them serve the same primary function (ie. weighing products), some differ in terms of methodology and design. One of the more popular designs used in manufacturing environments is the checkweigher conveyor, a design that consists of a static conveyor belt, a load cell, and a digital display. Products can be manually placed on the weighing module, and the checkweigher will then measure the weight of each product as it is passed over the load cell.

An in-line checkweigher is the term used to refer to a checkweigher that has been integrated into a production line. As products automatically move along the conveyor belt, the in-line checkweigher uses various sensors to detect, measure and sort the product based on the packed-size weight. The in-line checkweigher compares the weight of each product to a pre-set target weight range to ensure the weight of a packaged product matches the weight printed in the label. If the product falls outside of this range, it is sorted or rejected from the production line. Checkweighers can also be programmed to reject products that are outside of acceptable weight ranges or that have other quality defects or safety issues.

What products can you inspect on a checkweigher?

Checkweighers are used in a wide variety of industries and have become a significant tool in ensuring that products are weighed and inspected accurately to meet your specified limits. They help companies comply with regulations and improve product quality and traceability. Here are just some of the many industries where checkweighers are ubiquitous…

Food Industry –

Checkweighers are widely used in the food and beverage industry to guarantee that packaged consumer foods meet the required weight standards set by government regulations. Manufacturers must ensure that their products are at the correct weight, and checkweighers play a critical role in achieving this.

Construction Industry:

Checkweighers are used to weigh materials such as cement, sand, and gravel to ensure that they meet the specified weight and quality standards.

Logistics & Distribution Centres –

Checkweighers are used to weigh packages and parcels to ensure that they are within the specified weight range for shipping and distribution.

Agriculture & Farming – Checkweighers are used to weigh harvested crops to ensure that they meet the weight specifications and are priced accordingly.

The Waste Management Industry – Checkweighers are used to weigh waste materials such as scrap metal, paper, and plastics to determine the pricing for recycling and disposal.

The Pharmaceutical Industry – Checkweighers are employed across the pharmaceutical industry to verify the correct dosages of medications, a function that can literally be the difference between life and death when it comes to assessing individual tablets and capsules and rejecting those that do not meet the acceptable weight range.

The Chemical Industry – Checkweighers are used to weigh chemicals and other raw materials to ensure accuracy across the manufacturing process.

The Cosmetics Industry – Checkweighers are used to weigh various cosmetic products such as lotions, creams, and makeup to ensure that they meet the specified weight standards.

How does checkweighing improve a production line?

There are many advantages with adding Checkweighers into your manufacturing process. The use of checkweighers can help with quality control, product uniformity, finding missing components or foreign objects, boost cost savings as well as enhancing overall productivity.

One of the key benefits of checkweighing is reducing product giveaway, ie. the amount of product that exceeds the stated weight limit due to overfilling or variation in product density. While this may sound like a small thing, it can translate into significant volume and cost savings for manufacturers, especially in industries such as food and beverage where the cost of raw materials is particularly high and margins are very tight. By accurately weighing each product and rejecting any that are outside the specified weight range, checkweighers can significantly reduce the amount of product giveaway, which can save manufacturers’ bottom line and resources.

Checkweighing can also help manufacturers ensure compliance with regulatory standards, such as weight and measurement regulations, as well as quality control standards such as HACCP (Hazard Analysis and Critical Control Points) and GMP (Good Manufacturing Practices). Non-compliance with these regulations may incur pricy fines and legal penalties, as well as reputational damage. Checkweighers can help manufacturers circumvent such risks by providing accurate and reliable weighing data, guaranteeing that the products meet the required specifications and standards.

The return on investment (ROI) for checkweighing equipment can be considerable. In addition to the direct cost savings from reducing product giveaway and avoiding potential fines for non-compliance, checkweighers can also provide valuable data insights that can help you reduce waste, optimise your production processes, and improve the overall quality of your products.

Checkweighers can also prove instrumental in improving a company’s sustainability efforts by reducing the amount of waste product and materials.

The Importance of Metal Detection in Preventing Food Contamination

Food Safety is a crucial concern for consumers and food manufacturers today. Australian food standards and regulations are world class, and most food manufacturers do everything possible to avoid all types of contamination to produce safe products for sale.

Occasionally however, food contamination can occur whether it be biological, chemical, allergenic or physical. In terms of physical contamination in the food production, metal is one of the most commonly found contaminant materials. 

Metal can be introduced at different stages of production, as it is heavily used in food processing machinery, handling equipment as well as supplementary tools and utensils.

Why is Metal Detection Crucial for the Food & Beverage Industry?

There are three main types of metallic contaminants that a food metal detector can sense: Ferrous (mild steel / cast iron), non-ferrous (lead / copper / aluminum), and stainless steel. All these metals have distinct magnetic conductive properties and can be detected to varying degrees using metal detectors.

Ferrous metals containing iron are generally the easiest to detect because of their strong magnetic properties. Conversely, non-ferrous metals which lack iron are not magnetic but they still have high conductive properties, making them fairly easy to detect as well.

The presence of stainless steel in food is usually the most challenging to detect as it is non-magnetic and has poor conductivity.

Environmental and product conditions such as moisture and high salinity can also interfere with a metal detector’s ability to effectively detect contaminants.

metal detection equipment

With the right metal detection equipment, food manufacturers can ensure the safety and integrity of a wide range of food products, by detecting foreign metal contaminants during the production phase, and ensure that these contaminants are removed well before it gets to the supermarket shelves.

Installing food metal detectors at vulnerable points in the food processing stages can help eliminate even the smallest metal contaminants in products.The use of Metal Detectors also guarantees the regulatory food safety compliance legislation set by FSANZ (Food Standards Australia New Zealand) is met.

Compliance with the FSANZ (Food Standards Australia New Zealand)

Food Standards Australia New Zealand (FSANZ) is a statutory authority in the Australian Government that regulates and develops various food standard protocols. They strongly suggest using a range of inspection equipment for all Australian-based food processing industries to eliminate foreign contamination in food items.

Do you Need to Invest in a Metal Detector?

Metal detectors are integral to QA procedures in today’s food manufacturing industry. Metal detectors ensure that your food plant is manufacturing consistent, quality foods for consumers and following the guidelines set out by FSANZ and Australian supermarket giants (Coles, Woolworths, Costco, Aldi etc).

Metal detectors can significantly improve the detection levels of metal contaminants, and their automated nature provides greater efficiency for your production workflows. In addition, operators can easily generate QA (Quality Assurance) reports that help with measuring and documenting the quality standards of the finished goods.

Frequently Asked Questions

1. Is it worth buying a metal detector?

Prior to automated systems, many manufacturers frequently employed ‘sample testing’ to detect abnormalities, and they underestimated the effectiveness and efficiency of employing a metal detector in their factories.

Sample testing can be labour intensive and expose the company to greater risk compared to automated systems as only a subset of products are inspected.

Metal Detectors provide an effective measure to safeguard their food from unwanted contaminants, provide brand protection, and reduces the risk of expensive recalls or potential lawsuits.

2. Is metal detection a preventive control?

Metal Detectors are used to validate a product is free from metal contaminants, including ferrous and non-ferrous metals. Metal detection can be considered a preventive control to protect your food items against these undesired contaminants.

Food processing equipment can be vulnerable to aging, deterioration due to chemical reactions with cleaning products, and other environmental materials. Hence, a metal detector becomes a great preventive control.

3. Should manufacturers consider running product tests prior to selecting the right metal detector?

It is essential that product testing is carried out prior to any purchase to determine the product effect, and the ability of the particular metal detector being able to detect metal contaminants effectively.


The importance of metal detection in preventing food contamination cannot be understated.  Packaged food manufacturers should carefully choose the right inspection system to get the best possible performance and consistent quality in their processing line.

Investing the time up front to carry out product testing to understand the product effect (i.e. moisture and salinity levels) should be executed prior to selecting the right metal detection system.

Key steps for a manufacturer should follow when considering whether to purchase an x-ray system:

Conduct a Hazard Analysis

When considering investing in an x-ray inspection machine, manufacturers should conduct a Hazard Analysis for every product they produce, assessing the risk of contaminants being present. By doing so, they can identify where best to allocate their resources in order to maintain safe and contamination-free products. Additionally, this process can help identify potential hazards that may not have been considered otherwise, and allow for the development of preventive measures to mitigate these risks.

Identify Critical Control Points (CCPs)

An x-ray system is an important tool for detecting contaminants in food. When selecting a location to install an x-ray system, it is important to consider the critical control points in the production process. The x-ray system should be placed in a location where it can best detect contaminants in food. A CCP is a step or process essential to ensuring the highest levels of product safety; it’s the point at which control must be applied to reduce the risk of contamination to acceptable levels.

Define commercial and operational needs

It is important to first define your specific commercial and operational needs. Some questions you may want to ask yourself include:

  • What specific foods do you need x-rayed?
  • What are the maximum dimensions of the food items you need x-rayed?
  • What are the minimum dimensions of the food items you need x-rayed?
  • What is the maximum weight of the food items you need x-rayed?
  • What is the minimum weight of the food items you need x-rayed?
  • What is the thickness of the food items you need x-rayed?
  • What is your budget for this project?

Assess the x-ray system’s key functions

The food x-ray system meets all of the key functionality requirements that were set for it. This system is able to quickly and accurately detect foreign objects in food, which helps to ensure the safety of the food supply. Additionally, the system is easy to use and provides clear images of the food products that are being scanned.

  • Is it easy to use?
  • Can operators be trained quickly to use the x-ray system?
  • Does it enable quick product changeovers?
  • Does it allow easy storage and retrieval of date-and-timestamped
  • Images and data, for full traceability?

The food x-ray system’s key functions are to ensure that food is safe for consumption and to detect any foreign objects that may be present in the food. The system is also able to identify any abnormalities in the food, such as contamination or spoilage.

 Consider final factors

Overall Equipment Effectiveness (OEE) is a measure of how effectively a machine is being used. OEE is calculated by dividing the amount of time the machine is running by the amount of time it should be running, and then multiplying that number by 100. This number tells you how much of the machine’s potential output is actually being achieved. The Food x-ray system must have an Overall Equipment Effectiveness (OEE) of 95% and a Total Cost of Ownership (TCO) of $2,000 per year. This system is a great value for the money and is highly effective in detecting food contaminants.

X-ray Inspection Detects a Wide Variety of Contaminants

Product Inspection

A&D’s advanced technology in the ProteX X-ray Series is best-in-class, designed with users and businesses in mind.

Detecting hazardous foreign contaminants in food and beverage production is one of the main reasons why food manufacturers implement X-ray inspection as their final critical control point.

By inspecting final products with X-ray technology, food and beverage manufacturers are able to ensure that all of their packaged products are free from hazardous physical contaminants that could pose a safety risk, or cause a large-scale product recall.

Product inspection is critical in quality control and ensuring optimal quality assurance results. X-ray systems are incorporated into a production line and can inspect the product’s content to judge whether they are consistent throughout production batches.

This type of overall quality assurance helps food and beverage manufacturers enhance the production quality and brand image by rejecting non-conforming packages from the production line. It also helps to identify where the low-quality products originate from.

Some key features the A&D ProteX X-ray systems have are:

  • Advanced Algorithms
    Built for more than just containments, we also provide mass estimation, shape detection, and component verification.
  • Compact Design
    Our equipment is the smallest in class to allow for easy in-line integration with minimal reconfiguration of existing equipment.
  • Easy to Read Display
    A 15-inch color touchscreen provides users with a vibrant screen for viewing high-resolution imagery.
  • Streamlined Product Setup
    Minimal inputs from the user makes setup and changeover quick.
  • Quick-ship Available
    For manufacturers who need product inspection systems within a couple weeks.
  • Accelerated ROI
    Reject classification allows the operator to see trends in real time and correct issues upstream from the X-ray.
  • Service Simplified
    Local service to ensure maximum uptime.

A&D’s ProteX X-ray system uses advanced technology to detect a wide variety of contaminants and hazards, such as:

METALS: Metal, including ferrous, non-ferrous, and stainless steel can be detected via X-ray, even when inside foils and aluminum cans.  This is important in almost all manufacturing industries, as components can break at any point during production, and should that happen, the product should be rejected before final packaging.

X-ray inspection of metals

FLAVOUR AND SUGAR CLUMPS: Unlike some of the other contaminants, flavor or sugar clumps may not be much of a health hazard, but they do negatively impact the experience consumers have with your product or brand.  X-ray detection can find inconsistencies such as these to improve your consumer’s experience when it matters most.

X-ray inspection of clumps

GLASS: Glass contaminants, including glass shards, can be particularly important to detect when producing products with glass containers, especially in the food and beverage and other consumer packaged goods industries.


PVC AND TFE PLASTICS: Due to the use of plastic in a variety of packaging and manufacturing applications, detecting PVC and TFE (Teflon) plastic is very important. From gaskets or plastic handles lost during production, to plastic fragments that may break during packaging of your product, detecting PVC plastics can be an important part of your X-ray processes. 

In addition to simply detecting physical contaminants in packets, today’s X-ray systems can be applied to multiple purposes. They can act as multi-tasking protectors of the integrity of your products and subsequently the quality of your brand.

The ProteX X-ray system provides product inspection functions that cannot be accomplished by metal detection or checkweighing alone:

  • Measure product mass
  • Check fill levels
  • Seal integrity
  • Identify faulty, irregular shapes
  • Spot component inclusions / absences

X-ray systems have a minimal footprint, with a single unit performing multiple tasks as opposed to using several different machines. Additionally, with a single set-up screen, line changeovers are quicker and easier, reducing the risk of errors and keeping production downtime low.

Metalised packaging and quality control

In food and pharmaceutical packaging, foil trays, aluminium trays, aluminium foil, foiled bags and sachets are commonly used. 

Metalised packaging is used for many reasons as they provide a complete barrier to light, moisture, oxygen and bacteria, and in turn helps to increase shelf-life and to improve the presentation of the food.

However, metalised packaging is often not compatible with conventional metal detectors and so it is unlikely to meet supermarket and retail requirements. When using a metal detector, metalised packaging creates a large product signal which can force the metal detector to operate at inferior sensitivity levels than mandatory.

The solution to this is an X-ray inspection system. X-ray inspection machines excel at detecting high-density foreign objects in most products, even if they have metalised packaging.

Ice Cream Inspection

X-Ray inspection is fundamental to quality control and delivering on brand promises.

Additionally, the ProteX X-ray system provides additional product inspection functions that cannot be accomplished by metal detection or checkweighing alone

Missing Product Detection
In scenarios when the total weight of a product is acceptable, X-ray can be used to visually inspect and reject a product if there is missing product inside the package.

Shape Detection

Shape Detection
X-ray can be used to find inconsistencies in products that should be rejected, like broken or incomplete products.

Package Check
In instances where the product shifts during the packaging process, it may be important to check the seal of the product.

Seal Detection

Products with clips and oxygen absorbers can be masked to check for presence and avoid a false detection.

Ice Cream Test Inspection

Features and Benefits of the A&D ProteX X-ray include:

  • Automatically records every packet across the line

X-ray inspection, metal detection or both – which to consider?

X-ray inspection, metal detection

Hygiene and safe operations are imperative for all Australian food processing companies. In addition to bacteria such as salmonella and listeria, foreign objects can also cause contamination in food products.

Even with stringent processes and procedures in place, there is always the chance that foreign objects can make their way into products that can cause harm.

There are two primary methods for ensuring the quality of your product production line and detecting these foreign objects: food metal detectors and x-ray inspection systems.

Which of these systems is best for your food processing operations?

This article will explore the paybacks of each and when they should be applied for maximum benefit.

Product recalls in Australia

Product recalls in Australia

All food processing organisation would like to believe that its operations are completely fool-proof and that a product recall is unlikely to occur. But the bottom line is, despite our best efforts, food products can become contaminated and product recalls have been on the rise in recent years.

Food Standards Australia New Zealand (FSANZ) co-ordinated 763 product recalls between 2011 and 2020 which included a peak of 109 recalls in 2020 alone (compared to 67 recalls in 2011 and 42 in 2013). This increase is also linked to many companies becoming more aware of product safety and initiating these recalls voluntarily to avoid any harm coming to their consumers.

Food recalls in Australia

Protecting your brand and avoiding product recalls

Product recalls can harm your brand in many ways. Firstly, and most obvious, are the safety issues that come with contaminated food products. Fragments of plastic, metal, wood, glass, or other foreign materials can cause great harm to consumers.

If a consumer is harmed by these products and the company found to have been negligent in its operations, the potential for a company to be implicated in a lawsuit can cost millions and have serious consequences by damaging the company’s reputation.

However, product recalls can be damaging in other ways. Labour costs and costs to reproduce the product, all add up to a considerable amount of time and money, and ultimately can be incredibly damaging to a company’s bottom line.

It is not just the wallet where food processing companies are hit, their image is also impacted as well. Product recalls are generally reported by the media and can tarnish your reputation. Consumers will associate your brand with defective or dangerous products and are likely to discontinue purchasing from your company.

This is amplified in the modern age by social media which can lead to contracts with retail chains and stores being terminated. So, as you can see, there are not just the direct costs associated with product recalls, but numerous indirect expenses as well, adding up to a large sum of money and damage to your brand.

Food safety inspection systems – foreign body detection methods

To prevent dangerous foreign objects and contaminants from making their way into food products, it is essential to include monitoring devices on the production line to detect them before they reach retail shelves and the hands of the consumers. The two primary systems are x-ray inspection systems and metal detectors.

Choosing the right systems for the right application is vital for the safe operations of your food processing company, and also for your customers. The first step is assessing your production line and identifying the possible contaminants that could potentially get into the products.

If metal is the only possible foreign object that could contaminate your products, then metal detection systems become imperative. Because these inspection systems are specialised for metal detection, they are going to pick up even trace amounts of metals that are low density (like aluminium). This includes ferrous metals (that contain iron) and non-ferrous metals along with all stainless steels, whether they are magnetic or not.

If there is a chance that a variety of different contaminants can infiltrate your food products, x-ray inspection systems are the best solution. They will be able to pick up a range of various materials including stone, glass, plastic, rubber and even bones.

These systems have a range of other benefits as well, including the ability to measure mass, count components, identify missing or damaged products and can also inspect seal integrity.

Metal detection or X-ray inspection?

There is no method that is superior across all food preparation, packaging and processing operations because each operation is different. Metal detection and X-ray inspection systems have their capabilities, benefits and applications. Sometimes metal detection is the best solution, sometimes it is food X-ray detection systems, and at other times a combination of both across multiple critical control points that will deliver the safest outcomes.

Metal detectors are the right choice for companies where the individual product packaging does not have any metal/foil components, and where metal is the only contaminant that is likely to impact the food processing operations. This is especially true for operations where aluminium is used because it is extremely light and trace elements are more likely to be discovered through metal detection than X-ray inspection. This is also the best solution for operations that are gravity fed. If you have sensitive equipment that can be damaged by metal fragments, metal detection systems are also advisable.

X-ray inspections are the best solution when there are multiple potential contaminants besides metal. It’s also highly useful for inspecting products that may have metal packaging. Using X-ray systems will also give you the ability to inspect for broken or faulty products and packaging.

When should you use both? Often, contracts with retail outlets will require you to use both methods so they can be assured of a safe product. It also ensures you are meeting all regulatory requirements and standards and providing the safest possible product for consumers.

Factors to consider when choosing a solution

Determining what contaminants could be present is the first step, so a Hazard Analysis Critical Control Point (HACCP) audit should be conducted, or a Hazard Analysis and Risk-Based Preventive Controls (HARPC) for companies that are packaging seafood or juice.

Choosing the right technology may depend on the location of CCPs. Depending on the production process, specific foreign bodies can pose different risks at different locations on the line. A different technology at the location of each CCP can be the best solution.

Sometimes the nature of the product line will dictate which system is required. For example, gravity-fed lines will need metal detection while food X-ray inspection will be required for products that are packaged in metal.

No matter which solution you choose, some considerations should be applied to both. Choose a solution that is reliable, easy to use, efficient for product changes, and can be routinely tested. To reduce the risk of recalls, it is crucial to invest in hygienically designed equipment for product inspections. The technology should be easy to clean and durable enough to withstand regular cleaning without corrosion or degradation.

Waste management should also factor in your decision and investing in the latest technologies to be installed at the right CCPs will help to eliminate unnecessary waste production and protect your machinery from being exposed to products that could damage them causing costly repairs and delays.

Choosing the right supplier – A&D inspection

Whether you require metal detection, X-ray systems or both technologies, choosing a reputable supplier is essential to ensure your solutions meet all regulatory requirements, are safe and easy to clean and maintain.

AP Custom Ramp and Barriers

Australia Post is the main provider of parcel delivery within Australia, and with the increase of online orders, we are seeing a dramatic shift happening in the postal industry. The number of parcels being moved around Australia has exponentially increased in the last 5 years.

To keep up with postal demands, A&D were recently contacted by Australia Post to assist with streamlining part of their weighing process at one of their distribution facilities.

The customer’s objectives were clear:

  • Improve the current process of recording the weight of large trolley bins.
  • Ensure it can work within the facility’s space limitations.
  • Ensure it is robust to withstand heavy parcels.

The A&D Weighing team went to work and constructed a custom base manufactured specifically to weigh Australia Post’s large trolleys whilst being mindful of the facility’s space limitations. A RS-232 option was also installed in the AD4406 indicator to provide weight data output to their data system.

The customer advised A&D that the cumulative weight of the various express post parcels in the trolleys generally did not exceed 500kg. In this instance however, the scale was set to 600kg x 0.2kg to future-proof the scale for possible heavier bins if required.


The operators can simply wheel the trolleys into place via the small ramp in front of the drop centre scale. The ramp was specifically designed to ensure a smooth transition onto the scale, and the protective highly visible yellow barriers were also made by A&D to prevent people from walking over the scale.


The A&D solution:

  • Improve the ease of recording accurate weights.
  • Lower OH&S risk for operators pushing heavy trolleys onto platforms.
  • Incorporate safety barriers to remove likelihood of tripping hazards occurring.

Australia Post appreciated being able to come to A&D to get all aspects of the job done by one contractor, and A&D Weighing continue to prove that economical, Australian designed and manufactured solutions are a vital resource for local industry.

Weighing Animals with a Portable Trolley


The Australian Department of Agriculture and Water Resources recently contacted A&D Weighing to create a customised portable trolley for a Post Entry Quarantine (PEQ) facility.

Australia currently enjoys very good animal health status, and is free from a number of cat and dog diseases. To ensure this continues, animals entering the country have to undertake a period of quarantine on arrival. Once the animals arrive at the quarantine stations, they will be checked and weighed.

A new PEQ facility in Mickleham, Victoria contacted A&D Weighing requesting a simple method to weigh incoming animals, primarily dogs, at their kennels rather than bringing them into a building, to avoid cross contamination and possible infections.

Their requirements were:

  • To quickly and accurately weigh animals whilst they are on the trolley.
  • In cases where the animal may be aggressive, it should be possible to weigh the animal whilst they are secured in a cage.
  • The weighing solution needed to be able to weigh animals in extra large cages.

The SD-200 trolley scale is fully portable and easy to manoeuvre, making it convenient to be moved around as and when needed. Its sturdy construction also allows it to handle large cages and heavy animals.

Animals don’t usually stay still whilst being weighed, which is why it is important to use a highly stable portable trolley scale. The SD-200 scale comes with a battery operated LCD display that is clearly visible, which means quarantine officers will be able to get the weight measurements quickly.

As the facility needed a scale to accommodate larger animal cages, this meant that a larger weighing surface than the normal SD-200 would be needed. As such, A&D manufactured an extra large stainless steel platform to suit.

A&D Weighing is proud to be part of this project and to be able to assist in a customised weighing solution.

A&D Technology Reducing Downtime Costs

Grain sampling stations are located in some of the most remote locations on earth, so on-site technical support and downtime contingencies can be a costly affair. With valuable and sensitive instrumentation centric to the sampling process, technicians have to be diligent and well trained to ensure long term reliability is achieved.


Unfortunately, from time to time “Accidents Happen” and the simplest of mistakes can lead to large repair costs and extended down-time, exacerbated by the remote location of grain sampling labs. Aside from an accidental “coffee spill”, the dusty nature of grain labs play havoc with electronic instruments. Once fine dust starts to build on circuitry, it’s only a matter of time before performance is compromised.

A&D’s precision balances mitigate many of these risks by having IP-65 dust and moisture ingress protection on their legal-for-trade FZ-WP balance range. Historically, adding this level of protection to a 1mg or 10mg weighing instrument results in significant cost increases over non dust/waterproof versions. A&D Japan’s R&D division has changed that situation with the FZ-WP with pricing actually lower than past models used in the grain industry. These precision models are already popular, with over 200 units deployed to grain sites in the last 24 months. A&D have added a square weighing pan as a specific add-on to suit grain testing requirements, and have approval certification from the National Measurement Institute in Sydney (NMI cert. 6/4C/269) ensuring legal compliance with Weight’s & Measures regulations. A&D report that their short but effective YouTube video tells the simplest of stories and creates significant interest for this new level of protection in precision weighing instruments.

Desorption kit for volumetric approximation of produced gas

The desorption kit consists of a quick-latching Camlock canister and water reservoir connected by some tubing. A sample of material from which gas is evolving is placed in a sample holder which, in turn, is placed in the body of the canister. The camlock lid is locked in place, and the accumulating gas increases pressure inside the water reservoir. Water is displaced and collects in a beaker for estimation of produced gas volume.

Gas may be produced at varying rates and gas expulsion trends could be a critical part of a project – a technician may be required to monitor and record the displaced water volume at high rates of expulsion, which can be a demanding and restrictive task. The ideal solution would be to include equipment that can accurately measure gas production and send data directly to a laptop or data logger. In this example here, A&D can provide that solution and significantly help to save time and effort.

A beaker placed on the weigh pan allows the scale to measure the increasing weight of water, and stream data directly to your laptop via RS232 or USB cable. In this application, our software allows the user to set the preferred acquisition rate.


This type of solution can be applied in the resources industry with coal seam methane and unconventional gas exploration being prime candidates. Samples of fresh coal, drill cuttings or sidewall cores can desorb gas at measurable rates and the displaced water (mL) is a close approximation to the evolved gas volume (cc).

The kits are portable, straight-forward to use and disassemble for transport if necessary. The range of A&D scales complement the kits and allow the operator freedom to perform other duties rather than visually document the produced volumes. For a setup like this, you can use the EW-i Series Portable Triple Range balances, which can be approved for trade in accordance the National Measurement Institute of Australia.


Customised Platform Scale for the RAAF

A&D Weighing were proud to support Gould Instruments (one of our long term Dealers based in Townsville, QLD) to develop a solution to help ensure the weighing accuracy of shipping boxes at RAAF Townsville.

The primary objectives were clear:

  • Supply a weighing solution that can weigh bulky shipping boxes up to 3T.
  • The scale needs to have a low profile footprint of 2.5m x 1.5m.
  • The scale needs to be robust and suited to the outdoors.

Our A&D engineering team went to work and designed a low profile, three tonnes capacity pallet scale manufactured from galvanised steel to withstand demanding outdoor conditions. This scale is then simply connected to an elevated waterproof indicator where weighing measurements can easily be seen by the operator.

Large Capacity Pallet Scale

This is another example of A&D Australasia continuing to provide high-quality weighing solutions to industries in Australia and New Zealand.

Lakes Entrance Fishermen’s Co-operative

When it comes to commercial weighing equipment, there may be plenty of fish in the sea, but world-class processing solutions is a far rarer catch.

The achievements Lakes Entrance Fishermen’s Co-operative have accomplished is a great success for the seafood industry and we love sharing our clients’ stories…


The Company

In 2014, A&D Weighing commenced work with the Lakes Entrance Fishermen’s Co-operative Ltd (LEFCOL), one of Australia’s largest fish receivers located in Eastern Victoria. The primary catch they receive is Eastern School Whiting, a lesser known relation of King George Whiting. LEFCOL receives about one third of the national school whiting catch, which totals 1200 to 1300 tonnes per annum, and are now developing commercial quantities of value-added products.

The Challenge

The huge volumes at hand would need to be matched with custom filleting equipment, which LEFCOL had managed to source successfully. However, the job was far from complete. LEFCOL first needed to procure a custom grading system to grade the huge volumes of whiting they were receiving each day.

During their research, LEFCOL found that existing seafood feed-in technology was far too expensive and didn’t work effectively in sorting fish with a variation in size of almost 70% (from 15-25cm long). They needed an automated system that was not only accurate, but fast and capable of grading thousands of fish each day.

The A&D Weighing Solution

By gaining an intimate knowledge of the nature of LEFCOL’s operations, we were able to design and manufacture a custom checkweigher specially optimised to grade the whiting they were receiving, factoring in everything from their size and shape, to variations in their firmness during winter and summer.

The A&D EZI-Check checkweighers have fast moving conveyor belts which can quickly capture the weights to within one gram. Air jets triggered by the weights then sort the fish into predetermined categories – currently four, with options for up to six. Depending on the weight category they fall into, fish can either be sold for bait or pet food, set aside for automatic filleting, or sold fresh to domestic wholesale markets.

The Result

Thanks to A&D Weighing’s custom checkweigher and other complimentary processing equipment, LEFCOL can now grade up to 200 fish per minute. Not only are they able to get the whiting from net to plate faster and fresher than ever before, the checkweigher’s ultra-precise measurements encourages fishermen to catch and target larger fish. This allows LEFCOL to generate better profits from the fish they process, while smaller fish are given a chance to grow.

There’s no doubting it, A&D Weighing equipment is the reel deal. If you’re in the market for weighing equipment specially customised to your product, get in touch today.

Redsun – Taste the warmth!  

When you taste the beautiful sweet tomatoes that Phuong & Van Le grow at their family farm 40km north of Adelaide, you can tell they put their heart & soul into what they do.  Sweet, bright & bursting with flavour, their advanced glasshouse facility produces some of the best tomatoes you will ever taste and it’s no surprise they have been on our supermarket shelves for several years.  Phuong is a natural green-thumb and when he’s not focussing on their commercial crops, he’s keenly nurturing his hobby plants in the form of Asian family favourites like Bitter Melon & Custard Apple.


Running a major glasshouse facility is a massive task, especially with a young family.  Phuong & Van know that having the right processing & measuring systems in place is paramount to success.  Three years ago when they were undertaking a rapid expansion, Phuong was one of the first people in Australia to invest in A&D’s EZICheck™ inline weighing system and it has served them well; automatically checking and recording hundreds of thousands of punnets, ensuring only optimal weights leave the premises.

When it comes to weighing equipment there is a lot of choice out there and Phuong sums it up when he says “we don’t buy scales, we invest in peace of mind and A&D delivers just that”.  Reliability is a given with any Japanese equipment but with A&D it’s the combination of simple, efficient & reliable technology with local advice & backup whenever you need it.

Scaling up the battle against cane toads


Recently we were contacted to assist in the research of one of Australia’s biggest pests – Collingwood Supporters. OK; Cane Toads!

Cane toads are regarded as a prototypical case of a feral species (others being rabbits, foxes, cats) and are considered a major threat to our Australian ecology as the species has dispersed very effectively throughout Northern Australia over a short period of time.

The long-term effects of cane toads on the Australian environment can be difficult to determine, however some effects include the depletion of native species that die eating cane toads; the poisoning of pets and humans; depletion of native fauna preyed on by cane toads; and reduced prey populations for native insectivores, such as skinks.

Emily Gregg a researcher from Melbourne University contacted A&D Weighing as her research team needed to investigate water loss and water uptake in toads to better understand how the toads can survive in such varying environments and habitats. It is hoped that this research into the study of the cane toad’s survival will assist in vital further management of this invasive species.

Emily and her team are conducting field work with live moving toads so she requires a scale that can quickly measure weight, is light and portable, and that she can easily tare for accurate results. Our A&D HT Series scale is ideal for the job.

Below is a photo of Emily and her supervisor Reid Tingley carrying out a typical check.

This is another example of A&D Weighing continuing to prove that economical, Australian supported solutions are a key resource for local industry.


Complete Control for Riviera Bakery

A&D Weighing rose to the challenge to solve a problem for one of Australia’s favourite bakers Riviera Bakery recently.

Riviera Bakery have an existing batching system (not an A&D product) which they have had for many years. This batching system is used to load up the flour bins to help produce the freshly baked loaves and rolls delivered across Australia every day.

Control Cabinet

However with Riviera Bakery’s popularity increasing and their volumes and variety of baked goods expanding, Riviera’s productivity was restricted by their slow batching system which could only store pre-set target weights to batch out the preselected amount of flour.

Riviera Bakery’s objectives were clear:

  • Required a simple, effective food grade solution.
  • Needed to fill the hopper with accurate measurements of flour depending on what product and what product quantity they were looking to create (up to 100+ blend combinations).
  • Required a fast and variable target setting method that their operators could easily dial up.

The A&D Weighing team inspected the existing batching system and was quickly able to deliver a solution within budget and time-frame. A&D replaced the existing controller on Riviera’s batching system with a new control cabinet. The control cabinet included an AD4401 high performance batching indicator and large rotary dials. Now the operators can simply dial variable target settings for each flour batch required.

Additionally inside the control cabinet, there are smaller rotary dials for the manager to adjust the free fall value depending on required consistency and density of the flour in the storage hopper.

Improved Control Cabinet

The benefits are significant and return on investment rapid:

  • Faster, more efficient weighing process, releasing extra labour for other tasks
  • Improved batch QA & QC – able to record gross batch weights and individual flour weights
  • Locally designed & manufactured solution, easily supported by their local scale service provider

Most A&D scales, balances and weight indicators can be expanded in this way. A&D Weighing continue to prove that economical, Australian designed and manufactured solutions are a vital resource for local industry.

After all, if you don’t measure it, how can you control it?

Quality Assurance in the Pipelines

Quality Assurance in the Pipelines

A&D Australasia’s Weighing Division recently solved a problem for a large local plastics manufacturer based in Melbourne. This manufacturer produces scores of plastic pipeline for many high profile companies and projects which include: water and waste water plants, mining and mineral processing, food processing companies, power stations, hospitals, schools, and high rise developments just to name a few.

Being a leader in their industry and priding themselves on constantly improving their manufacturing processes to increase efficiencies whilst adhering to quality systems that conforms to Australian Standards, this manufacturer wanted to find a faster and more cost effective method of measuring the moisture content in their pellets of polypropylene plastic which is used to manufacture their plastic pipelines.

We were told that measuring moisture content particularly in the early stages of the manufacturing process was critical. If there is too much or too little moisture left in the pellets of polythene plastic after they have gone through the drying process, then the consistency of the moulded pipes could be weakened and could result in leaks in the pipes.

Looking to move away from their current time consuming titration method which often requires costly specialized equipment, the manufacturer purchased an A&D Advanced Moisture Balance with SRA (Secondary Radiation Assist) Technology and are now able to get accurate moisture content measurements in a much shorter time.

Quality Assurance in the Pipelines2
Some significant benefits achieved from A&D’s involvement:

  • Faster and uniform moisture measurement with halogen lamp and innovative SRA technology.
  • Huge cost savings because the customer no longer needed to purchase replacement specialised titration equipment.
  • If required, live moisture data can be graphed to a PC using A&D’s WIN CT moisture software.
  • Locally supported moisture analysers which can easily be serviced by their local scale service provider.

A&D Australasia continue to prove that economical, Australian designed and manufactured solutions are a vital resource for local industry now and into the future.

After all, “If you don’t measure it, how can you control it?”

A&D were proud to support GP Graders (one of Australia’s leading manufacturer of cherry sorting and packing machinery) to develop a solution to improve the cherry filling process for eight new production lines at Cherry Hill Orchards in the beautiful Yarra Valley.

The main objective was to carefully transfer the picked cherries into crates, whilst also ensuring even distribution into all of the various bag and box sizes during the filling process.

Together with GP Graders’ world leading food processing systems, we developed a reliable and intelligent solution incorporating our A&D high speed AD-4402 Batching indicator controller that allowed seamless, uniform distribution.

See the video below on how it all came together.

Major Tomato Producer Implements Local Weight Data Solution

major-tomato-producer_1A&D’s powerful Multiweigher 3000 weight data suite has recently been implemented to capture the weights of tomato trusses growing in a new high-tech glasshouse just north of Adelaide.

With several Dutch automated process systems already in use at the glasshouse, A&D’s technical team were contacted to:

  • Facilitate better weighing accuracy which aligns with Australian Weights & Measures Guidelines;
  • To provide superior data capture intelligence compatible with the Dutch supplied equipment;
  • To provide local service and technical support.

Reviewing the customer’s requirements and taking the new state of the art facility into consideration, A&D’s locally approved & supported weighing hardware and the A&D Multiweigher 3000 software package became the obvious solution.

Firstly, the A&D technical team installed replacement indicators (A&D’s FSi-D models) to the pre-pack lines and the truss production lines. These indicators were fitted with wireless serial data servers which transmit the data via the company’s wireless network to a designated PC. These integrated seamlessly with the existing loadcells, minimizing physical disruption.


The A&D Multiweigher 3000 software allows the customer to accurately monitor the tomato truss production lines; ensuring better measurement control of their production operations. The A&D Multiweigher package allows capture of all weights, not only from the newly implemented A&D scales, but also from the customer’s existing inline checkweighers.

Furthermore, A&D installed an optical counter at the end of the production lines to cross check the count data, validating the production accuracy all managed by the single and very cost effective software package.


Some significant benefits achieved from A&D’s involvement are:

  • Waste reduction & minimised giveaways
  • Improved cost savings / profits
  • The facility to monitor operator efficiencies

A&D Australasia continue to prove that economical, Australian designed and manufactured solutions are a vital resource for local industry and are proud to continue to work with this SA tomato glasshouse facility to produce quality prime fruit now and into the future.

    A&D weighs out inconsistencies in prison food


    In a bid to control prisoners’ food consumption and to ensure overall nutritional balanced diets within the jail, a NSW prison recently requested our help to suggest a better way of achieving consistent food portions.

    The current process saw the prison’s catering teams manually divide the daily food portions into approximate serving sizes without the aid of any significant measuring equipment. This process yielded inconsistencies with a few prisoners receiving either too much or too little food during meal service.

    Working together with local A&D Platinum Partner Precision Calibration Services (PCS), we suggested the use of A&D’s FS-6Ki scales to achieve accurate measurement control of the daily food portions. We also introduced the A&D Multiweigher 3000 to determine which teams worked best together thus improving overall yield.
    The solution was simple. Two FS-6Ki scales were set up at the portioning station in the central kitchen. The first FS-6Ki scale was used to weigh every portion to determine if too much or too little food was being served, and the second FS-6Ki scale was used to even out the inconsistencies.

    The A&D Multiweigher 3000 was also integrated in the portioning process to capture and measure which teams worked best together to provide the greatest consistency and efficiency.

    This is another example of A&D Australasia continuing to prove that economical, Australian designed and supported solutions are a key resource for local industry.

    Engineered Safety on Amusement Thrill Rides

    Thrill Ride Safety
    Some people love them whilst others fear them, but how safe are amusement thrill rides?

    Recently some of our A&D Techeng team based in Brisbane were called to support one of Australia’s most popular theme parks in Queensland.

    A new amusement ride was purchased by the theme park to invigorate attendance numbers particularly with the school holidays coming. However before the amusement ride could be released to the most daring of thrill seekers, a rigorous risk assessment was performed. This assessment is carried out on all new and existing rides to ensure all safety guidelines are met in accordance to Workplace Health and Safety Act 1995 (QLD) and AS 4024.1-2006 – Safety of Machinery.

    In this instance, the risk assessment found the thrill ride did not fully comply with compulsory safety requirements so our engineers where sought out to advise on possible solutions to improve the safety rating of the new amusement purchase.

    The requirements were reviewed and A&D Techeng found the optimal way to meet safety category ratings of CAT 3 and CAT 4, was to install an Allen Bradley CompactGuard PLC with safety IO on Ethernet/IP and category rated switches.

    A&D Techeng used the risk assessment to map out the electrical design (CAD), program the PLC, manage the electrical installation and commission the ride. The PLC was an ideal solution as it is used to monitor safety measures as well as being able to perform control functions for the amusement ride.

    Once the thrill ride was upgraded with the appropriate changes, the ride was then re-evaluated to ensure that the requirements of the risk assessment were achieved.

    With the safety of the amusement ride now successfully validated, we are sure this new exciting thrill ride will get even the most well-seasoned thrill seekers’ hearts racing. We thank the theme park team for choosing us to be part of this successful project.

    Wild about Game Meat


    Diners and restaurants are becoming more adventurous with culinary fare, and in the last few years we have witnessed a rise in demand for game meat in Australia as well as overseas.

    Making increasingly regular appearances on our menus are: kangaroo meat, rabbit meat, emu, and boar just to name a few. So with demand on the rise, a well-known and highly respected game meat processing company called upon A&D Techeng’s services to help improve their existing game meat tracking process, and to ensure they continue to deliver quality game meat of the highest standard to our domestic market as well as overseas.

    The customer’s objectives were clear:

    • Facilitate better tracking of the animal from the truck to the cool room.
    • Improve the current process of recording stock with greater accuracy and efficiency.
    • Devise a catchment operating system for any barcodes that require manual recording.

    Game-Meat-Solution2 Reviewing the customer’s requirements with the assistance of A&D Partner Able Scales in Brisbane, and using barcode scanners, Schneider SCADA & HMI System, Allen Bradley Micrologix, A&D Weighing’s IP65 AD-4407 indicator with analogue output option, and utilising existing A&D overhead-track OHT-600 scales, the team were able to design and implement an innovative system that can easily read, record and sort information quickly and easily.

    The system registers the shooter ID tag and the weight of the animal using the digits on the barcode (the barcode primarily identifies the type of animal, site reference, the shooter), and additional information regarding the truck number, the date, and time is also collated into a CSV file for further accounting and reporting requirements. If any barcodes are not readable/visible in the tag reading area, then the animal is automatically diverted to an alternative weighing station where manual entry is performed.

    The benefits are significant and return on investment rapid:

    • Faster and more intelligent weighing process, releasing extra labour for other tasks.
    • An efficient recording and tracking process that requires less time to complete.
    • Added peace of mind with improved accuracy and recording capabilities.
    • Improved batch QA & QC reporting and accounting.

    This is another example of A&D Australasia continuing to prove that economical, Australian designed and manufactured solutions are a vital resource for local industry.
    After all, “If you don’t measure it, you can’t control it”

    Is there Mushroom to improve?


    One of Australia’s largest family owned producer, packer and marketer of fresh produce has a reknowned reputation for quality and consistency, and are always seeking new and innovative methods to raise the bar.

    As part of their rigorous QA program, they identified scope for improvement in their mushroom picking operations.
    With state of the art spawn laboratories and the latest in growing environment measurement and control, they identified an opportunity to move away from their current process of manually recording the pick weights, adopting a more effective method of automatically logging weight data during the picking stage.

    Utilising A&D Australasia’s waterproof FS-15Ki trade approved scales with RS232 serial output, local A&D Australasia partner Able Scales implemented a precise and cost effective method of automatically capturing every finalised pack weight and was easily integrated into the company’s own grading software.

    With one simple button press, the pickers are able to log weight, time and date and the information is directly fed into the customer’s grading system for further processing.


    The Objectives are significant:

    • Logging the data facilitates accurate weight records, reducing operator error.
    • With payment based on picking productivity, digital data capture eliminates potential disputes.
    • By allocating logged data to specific pickers, the company is able to monitor productivity rates by batch and by individual operator.
    • Systems are easily supported by their local scale service provider.

    Not resting on their laurels, these leaders in the fresh produce space continue to establish best practice and innovation; maximising yields and reducing costs, whilst maintaining the highest quality standards. A&D Australasia were proud to be a key part of this success story with yet another innovative weighing solution.

    Printing a Better Weigh


    Webstar are one of Australia’s leaders in the print media space and have forged a reputation for unrivalled flexibility, quality and reliability. They print more than 150 magazine titles, catalogues and corporate publications each month. Always seeking productivity improvement opportunities, A&D Australasia were called upon to assist Webstar in devising and implementing an effective and reliable method to reduce overprint in some titles, i.e. make sure print runs were consistently closer to targets thus reducing waste in materials, energy and manual effort.

    Reviewing Webster’s requirements, A&D Australasia utilised their unique skill set of Automation Engineering and Weighing Instrument Manufacturing to take on the challenge.

    “If you can’t measure it, you can’t control it” is the mantra at the heart of A&D’s process improvement philosophies. Utilising a precision compact balance to set initial sample weights and a SCADA package custom-built by A&D TechEng, output weights were then tracked on a larger 2000kg scale with real-time feedback to the main system. Improvements to the commercial print operations were instant.


    Aside from the customised Electrical Engineering design by A&D TechEng, this project was rolled out using “off the shelf” A&D Weighing instruments and the local expertise & support of A&D Platinum Partner Precision Calibration Services (PCS).

    With their local know-how and responsiveness, PCS are able to support this system with ease, providing the client with complete peace of mind.

    • A&D EK Compact Precision Balance facilitates accurate sample weights for initial setup, reducing irregularities with insert materials.
    • A&D3000 2000kg Pallet Scale (proudly made in Australia) monitors the final mass output, eliminating the time and variance associated with manual counts.
    • A&D TechEng SCADA solution delivers easy operator interface and management feedback.
    • PCS provide local service and calibration support to keep it all running smoothly.

    A&D Australasia were proud to be a key part of this success story with yet another innovative weighing solution.

    Coffee Scale, Caffeine Hit on a Major Scale!

    A&D Australasia’s Weighing Division recently solved a problem for local boutique coffee blender and roaster Veneziano Coffee, with a customised, portable weigh hopper that reduced OH&S risks and significantly improved their blending process.
    Veneziano are renowned for their premium coffee so they expected a premium solution.

    Weighing Hopper Solution Objectives were clear:

    • Had to take the blending hopper to the 50kg sacks of imported raw beans – not the other way round (they don’t share our OH&S standards in places like Guatemala & Kenya – boy are those sacks heavy!)
    • Needed to accurately add small and large amounts (within 50g accuracy) to create up to 400kg blends.
    • Hopper was to be fully portable with battery or mains powered weight system on board.
    • Robust design from Food Grade Stainless Steel with oversize wheels

    The A&D Weighing design team went to work and the system was built, tested, inspected, delivered and training completed within budget and time-frame. Now the operators simply wheel the hopper to each pallet of raw beans, add the required amount to the hopper weigh scale, tare the A&D AD4406 controller before adding the next ingredient and so-on until the batch is completed. The hopper weigh scale is then wheeled into position under the vacuum pipe that extracts the beans up into the roaster.

    Next step – a fresh Veneziano Espresso!

    The benefits are significant and return on investment rapid:

    • Lower OH&S risk from carrying heavy sacks
    • Faster, more efficient weighing process, releasing extra labour for other tasks
    • Improved batch QA & QC – able to record gross batch weights and individual ingredient weights
    • Locally designed & manufactured solution, easily supported by their local scale service provider

    They also ensured a “future-proof” system by utilising a Weighing controller that would easily allow the client to add wireless scale weight communication directly to their production PC if ever required. Most A&D scales, balances and weight indicators can be expanded in this way. A&D Weighing continue to prove that economical, Australian designed and manufactured solutions are a vital resource for local industry.
