The metal detector machine is familiar to everyone. The metal detector machine uses a "balanced coil" detection head. The detector of this design can detect various metal contaminants. These include ferrous metals, non-ferrous metals and stainless steel in fresh and frozen foods. Products that are packaged or not can be tested, and products packaged in metal film can also be tested. Metal detectors are widely used and have many uses. They have become the main component of many food processing lines in Asia.

　　In China, food safety has always been very severe. No matter how strict the management procedures are in the production process, and the corresponding protective measures have been taken to deal with the influx of metal foreign bodies, it cannot be completely ruled out. Once these unqualified and unsafe products enter the market for sale, they will cause major harm to the health of consumers and also cause the company's product brand to drop significantly.

　　Pollution sources usually include the following four types:

Caused by raw materials, typical examples include: metal labels and syringe needles in meat products, metal wires in wheat, broken mesh wires in powder materials, tractor parts in vegetables, fish hooks, and metals in material containers Hook and loop and wire bundle.

　　 caused by human factors, buttons, pens, jewelry, coins, keys, hairpins, thumbtacks, pins, paper clips, etc.

　　 caused by maintenance, screwdrivers and other maintenance tools, metal cutting swarf and welding slag generated after maintenance, copper wire scrap after electrical maintenance, improper cleaning or negligence caused other items to be missed, and metal chips generated by pipeline maintenance.

Caused by in-plant processing, during product handling or processing, mills, mixers, mixers, slicers, and conveying systems can cause metal contamination, such as broken screens, metal fragments generated by milling machines, and recycled products In the foil.

　　The use of metal detector machine is a necessary means to prevent metal foreign matter from being mixed into products. As the first person responsible for food safety, food companies must earnestly take responsibility for protecting the health of consumers, their own brands, and establishing a food safety culture.
