Microwave sterilization system

Abstract

The invention provides a microwave sterilization system. The microwave sterilization system comprises microwave sterilization devices for performing microwave sterilization on products, an ultraviolet sterilization device for performing ultraviolet sterilization on products, and a sealing device for sealing products, wherein the microwave sterilization devices, the ultraviolet sterilization device and the sealing device are sequentially arranged, and the microwave sterilization system also comprises a conveyer belt for transporting the products, the conveyer belt penetrates through the microwave sterilization devices and the sealing device, and the ultraviolet sterilization device and the sealing device are both located at outlets of the microwave sterilization devices. The microwave sterilization system disclosed by the invention integrates microwave sterilization, exhaust sealing and ultraviolet sterilization, and a processing technology of firstly performing microwave sterilization on plastic bagged foods and then performing sterile sealing while the plastic bagged foods are hot is effectively realized, so that the sterilization time is effectively shortened, the sterilization effect and the sterilization efficiency are improved, bag explosion caused by microwave sterilization is avoided, besides, heat exhaust sealing can be realized, the degree of vacuum in cans can be increased, and the oxygen content is reduced. The device is high in sterilization speed, assembly line type production is convenient, the production efficiency is effectively improved, and the eating quality of bagged canned foods can be improved.

Description

technical field [0001] The invention relates to the field of sterilization devices, in particular to a microwave sterilization system. Background technique [0002] Soft canned food refers to the bagged food that uses composite plastic film bags instead of iron cans or glass jars to store food, and can be stored for a long time after sterilization. It has the advantages of light weight, small size, convenient opening and storage resistance, and has become the mainstream of canned food at present. At present, most domestic soft cans use traditional sterilization processes - high temperature and high pressure sterilization and water bath sterilization. During this process, the nutritional components of food are seriously lost, and the sensory quality of food is greatly damaged. [0003] Microwave sterilization uses microwave penetration performance to rapidly heat up food materials, reaching the sterilization temperature in a short time, resulting in the death of microorgani...
