An X-ray foreign matter inspection system for food products. The world’s most compact and least expensive such system, which also greatly reduces maintenance, it is meant for the world’s medium-sized to small food manufacturers, which are the overwhelming majority of food producers. Almost all foods found at supermarkets and convenience stores are processed at factories and then 100% checked using foreign matter inspection systems before shipment. Currently, the most widely used foreign matter inspection systems are for metal alone, but this system can also check for other foreign matter such as glass, bone, stone and plastic, as well as metal. It takes X-ray images and then analyzes them with original image processing technology, and instantly distinguishes foreign matter contained in food and automatically rejects defective products. Also, a new model (curtain-less type) has been added to expand the series in response to market needs to inspect products that are not yet packaged.
