Inspection Systems: Industrial Metal Detection
Why Metal Detection is Vital in the Food Industry
Contaminants such as industrial metal detection systems can enter the food production chain at any point, from raw materials to final packaging. Metals like lead, arsenic, and stainless steel pose serious health risks to consumers. Metal particles, whether introduced during machinery wear or via external sources, can lead to costly recalls, compensation claims, and damage to your reputation. Ensuring thorough industrial metal detection is not just about compliance—it’s about protecting both your customers and your brand.

10 Reasons Clients Choose FESS Group (And Why You Might Too)
Get StartedFood And Drink
Food processing plant design consultants can help you improve your plant’s energy efficiency, increase your rate of production, reduce lead times, and achieve 100 percent food safety compliance. However, they are also essential when you want to expand your operations.
Pet Food
Setting up a pet food production line is similar to a human food production line. However, as you might expect, there are some differences.
Pharmaceutical
Pharmaceutical engineering and plant design consultants help you expand pharmaceutical production lines in factories more efficiently and effectively. Their work includes regulatory compliance, validation, and implementing logistics services for maintenance and systems management. Most consultants assist firms from the initial concept stage onwards, guiding them through every step of the plan.
Petrochemical
Using an outside consultant for your petrochemical engineering projects can help you to maintain safety, efficiency and productivity like never before, all while minimising your spend and controlling your budget for your petrochemical plant construction.
What Is Metal Detection In Food Production?
Lead, nickel, arsenic, cadmium, copper, and selenium are common types of metals found in food, contaminating the entire food chain and harming public health. These metals can be introduced at any stage of the food production process.
However, you can use metal detectors to ensure the safety and integrity of various packaged, unpackaged, and bulk goods. Metal detection systems for food detect metallic contaminants. This happens during processing and packaging to ensure that no metals end up in the food we eat.
Why Is Metal Detection In Food Production Important?
Food industry metal detectors are crucial in improving safety standards before food consumption. They are, in fact, one of the benefits of technology in food.
- Companies use metal detection systems primarily for consumer protection. Consumers may be injured by metal particles present in food products, affecting their overall health.
- Food companies also use these inspection systems to protect their brand’s image. A company that sells contaminated food products is at risk of expensive recalls and hefty compensation claims. These recalls and compensations can lead to loss of consumer trust and a negative brand image, causing longer and more significant reputational damage. Luckily, a food metal detector can help you identify non-ferrous and ferrous metals like stainless steel and aluminium in time, preventing them from destroying your brand’s reputation.
- Metal detection also protects machinery from failure. This way, food companies can avoid production downtimes, costly repairs, and revenue decreases.
Types of Metal Detection Systems
At FESS Group, we offer various types of industrial metal detection systems to suit different stages of production:
- X-ray inspection systems: For detecting contaminants like bone, glass, and metal in addition to typical metals.
- Conveyor-based systems: Ideal for inspecting items like cereals, meat, fruit, and vegetables.
- Gravity fall systems: Effective for inspecting grains, powders, and granules.
- Pipeline systems: Perfect for liquid products such as sauces and dairy.
Looking to enhance your product safety and protect your production line? Contact FESS Group today to discuss how our industrial metal detection systems can help you stay compliant and avoid contamination risks. We are committed to providing solutions that protect both your brand and your customers.
How Metal Detectors Work In the Food Industry
A food inspection metal detector works with various detection methods. However, they typically use the transmitter-receiver method in the food industry. These detectors have a transmitter coil that generates a constant electromagnetic field alongside two receiver coils.
Any metal particle that passes through the detector will interfere with this field, causing the receiver coils to detect the signal. The metal detector’s electronic unit will analyse this signal to determine whether it is metal contamination. Then, the detector will isolate the product from the production line if it is contaminated.

Frequently Asked Questions
We have developed metal inspection processes and systems for many food manufacturers in the UK and beyond. Also, we have extensive experience assisting a wide range of industries with food metal detection, ranging from dairy to red meat. Our systems not only protect your products but also safeguard your brand from the financial and reputational damages caused by contamination.
Metal detectors for food production engineering have advanced significantly over time so it is unlikely that they would mistakenly detect food. However, if a food product contains iron, salt, or water, and so is conductive it can lead to it falsely detecting metal in a food. This is known as product effect, but it is not very common, and several types of metal detectors have settings that cancel it out to avoid food being incorrectly detected.
Metal detectors are essential pieces of equipment in food engineering that protect both companies and customers from metal contamination in food products. If a piece of metal is found and consumed it can present a serious choking hazard and other health issues. Not only that but the reputation of the manufacturer will be negatively affected, and they might even have to pay out compensation or a fine for breaching health and safety standards.
Multiscan technology is a key part of modern metal detection in food engineering services. Up to five adjustable frequencies can be scanned using this technology which significantly improves the likelihood of accurate detection. Multispectrum x-ray systems in metal detectors use a computer to pass a beam through a product which then bounces back and forms an image on the computer screen. A control system will then determine whether the product should be accepted or rejected based on the image.
A GMP (good manufacturing practice) inspection is typically carried out via an on-site visit by a specifically trained inspector. The purpose of the inspection is to ensure manufacturers are adhering to the minimum standards for their production processes. They can occur across different industries but are most common in pharmaceuticals. As experienced pharmaceutical engineering consultants, our team can help you continuously meet GMP standards and pass all inspections.
Our industrial metal detection equipment is designed to detect all types of contaminants, including ferrous and non-ferrous metals. They feature advanced settings to avoid false positives caused by food properties like moisture or salt content.
Industries such as food, pharmaceutical, pet food, and petrochemical rely on our systems to ensure product safety and quality. From dairy products to red meat processing, we tailor our solutions to your specific needs.
By preventing metallic contaminants from damaging your production equipment, our detection systems reduce the likelihood of breakdowns, minimizing production delays and repair costs.
