Metal Detector

Metal detectors for food primarily are used for the purpose of consumer protection. Despite maximum care metallic contaminations of food products during the production process cannot be fully excluded. Metal detectors for food provide effective protection against ferrous and non-ferrous metals (aluminium, stainless steel, etc.). They can be installed in every step of the production process and can be used for many different applications, e.g. for the inspection of bread and bakery products, meat and sausage product, fruit, vegetables, dairy products, spices, sugar, etc.

In addition to consumer protection, metal detectors also are used to protect machinery. Even smallest metal particles can lead to machinery failure. Expensive repairs and production downtimes are the consequences, often followed by revenue decreases.

When used for machinery protection, the metal detector is installed directly before the machine to be protected. If, as in most cases in the food industry, consumer protection is the goal, several inspection points are useful. An inspection of raw material has the advantage that metal particles are separated before they are broken up into smaller pieces which might be harder to detect. Inspections at critical control points (HACCPs) during the production process are recommended to notice machinery failures (such as broken blades) in time.
