Non-Ferrous Metal in the Food Industry


One of the greatest risks to food safety is the contamination of food by small metal particles, which may be imperceptible to the naked eye, but are harmful to health if inadvertently ingested and be a source of non-conformities. Non-magnetic metals such as stainless steel, aluminum or copper can contaminate food during the manufacturing process, either due to packaging defects, machinery abrasion or worn parts.

As they are, on the one hand, metals that cannot be attracted by the neodymium magnets with which we manufacture the magnetic filters, and on the other, continuous processes of bulk product where it is not possible to stop production after detecting the metal, In these cases, it is necessary to apply more specialized technologies to achieve the double objective of food security and productivity.

Solutions to extract non-ferrous metal particles in food factories with continuous production processes without the need for stops.

There are technologies such as X-ray metal detection, air blowing or eddy current separation, but one of the most widely used systems in the food industry are ejector metal detectors, due to their simplicity, efficiency and investment cost.

It is a metal detector that acts on both ferric and non-ferrous metals, suitable for installation by free or pneumatic carriers, which includes an expeller that extracts a minimum part of the product when the detected metal particle is detected. It is recommended to install it in combination with a magnetic filter that will separate the ferric particles beforehand.

Metal detectors for the food industry offer a manual or automatic compensation system for the effective product, we decide, our detectors incorporate a microprocessor that balances the signal that the product that is processed can emit the propio detector, avoiding this mode , expulsions and/or false detection signals, without the presence of metal. If the signal is canceled if false detections are made, the equipment is completely reliable and avoids the expulsion of unnecessary material. The user can monitor detections, extract information and modify operating parameters remotely from a PC via RS232, RS485 Ethernet communication. From the display of the propio detector you can enter up to 30 different settings to adapt the operation of the equipment to the product to decontaminate and meet the production conditions.

Also, the rest of the detectors and magnetic filters for the food industry, is manufactured in stainless steel and certified to comply with IFS standards.
