How does the food industry use metal detectors?


The main purpose of food metal detector is to protect consumers. Despite the best efforts, metallic contamination of food products cannot be completely avoided during the production process. Consumers may suffer severe injuries from metal particles in raw materials or during the production process. In addition to compensation claims and expensive recalls, there are numerous and serious consequences for the producing company. Negative brand image and loss of consumer trust are causes of even bigger and longer-lasting damage resulting from impure food products.



Food processing is most commonly affected by foreign materials. Further processing equipment can be damaged as a result of this contamination, but more importantly, it poses a safety hazard to consumers. In some cases, metal contamination in the food supply can cause irreparable damage to a company's reputation and reputation.


In a process flow, or as part of a packaged item, ferrous, nonferrous, and stainless metal detectors sense and remove them. The metal-detecting gaskets & grommets that come standard with all food-grade (or higher) products add a layer of brand protection and product protection.



Ferrous and non-ferrous metals (aluminum, stainless steel, etc.) can be detected by food metal detectors. The devices can be used in every stage of a production process and for a variety of applications, such as inspecting bread and bakery products, meat and sausage products, fruit, vegetables, dairy products, spices, sugar, etc.


Machines are also protected by metal detectors, in addition to consumers. Even the smallest metal particles can cause a machine to malfunction. A repaired machine often requires costly repairs and production downtime, which leads to revenue declines.


Capture


In the food production process, where are metal detectors installed?


Machine protection is administered by installing the metal detector directly before the machine to be protected. Several inspection points are helpful if consumer protection is the goal, as it is in most food industries. Inspecting raw material provides an advantage because metal particles are separated before smaller pieces are broken up, making detection more difficult.



To eradicate contamination to the fullest extent possible, food products after packaging are examined a second time with a metal detector (or an X-ray system).


Raw materials should be inspected several times for optimal product protection, and the final product should be inspected.


What is the purpose of metal detectors?


Several types of metal detectors are available, each using a different detection method. The transmitter-receiver method is commonly used in metal detectors in the food industry.


Two receiver coils and a transmitter coil are used with such metal detectors. A constant electromagnetic field is generated by the transmitter coil. Metallic particles pass through the detectors and interfere with the electromagnetic field, which produces a signal that is detected by the receiver coils. Within the metal detector, the electronic unit analyses this signal and evaluates it to determine if metal contamination exists. The food industry usually equips metal detectors with automated reject units that automatically remove the contaminated product from the production line.
