X-ray machine application - detection of foreign objects in soft canned food production
Flexible packaging cans refer to canned foods whose containers are made of soft materials (such as aluminum foil or aluminum-plastic composite, paper-plastic composite, composite plastic and other plastic composite materials). Such products include condiments (directly added to food after opening the bag), seasoned vegetables, meat, aquatic products or their mixed products, and dried fruits. The packaging bag is generally four-layer composite, and the bag without aluminum foil layer is generally transparent. Afterwards, if there are foreign objects or defective products, it cannot be inspected again, and cannot be detected by a metal detector, so foreign object control before bagging and sealing is very important. For food, any substance visible to the naked eye that should not be contained in non-processing requirements or according to product standards can be referred to as foreign bodies. Foreign bodies are divided into endogenous and exogenous. Substances that are contained in the raw materials and auxiliary materials of the product but are required to be excluded from the product are called endogenous foreign bodies, such as bones in meat; substances that are not originally part of the raw and auxiliary materials of the product but are mixed into the product are called exogenous foreign bodies, such as Metal, glass, hair, weeds, flying insects, chemical pollution, etc. Endogenous foreign bodies and exogenous foreign bodies are relative, not absolute. Hazards of foreign objects: There are safety hazards, such as metal foreign objects of appropriate size, broken glass, wood, stones, bones, which may damage the customer's teeth, scratch or trap the customer's mouth and throat; foreign objects containing chemicals, or chemicals Direct contamination of food may bring discomfort to the human body, or even poisoning. As long as it is an item in the workshop, it may become a foreign body in the product. There are many possible sources of these foreign objects, such as workshop signs or tools, and parts that are easy to fall off and lose on facilities and equipment. Foreign matter control requires a combination of hardware and management, and focusing on prevention can minimize the possibility of mixing - that is, focusing on reducing sources, focusing on inspection (manual selection), detection (metal detectors, X-ray machines, etc.) auxiliary.
