Process control of microwave sterilization equipment is very important

Microwave sterilization equipment Conventional thermal sterilization transfers heat from the surface of materials to the interior by means of heat conduction, convection or radiation. It often takes a long time to reach sterilization temperature. Microwave sterilization is through the direct reaction of microwave energy and microorganisms such as bacteria in materials. Thermal effect and non-thermal effect work together to achieve the purpose of rapid heating, and the processing time is greatly shortened. The sterilization time of various materials is generally 3 to 5 minutes, and the sterilization temperature is 70 to 90 degrees. Its characteristics are short time and fast speed. Bactericidal uniformity and thoroughness, low temperature sterilization, can maintain the nutritional composition and flavor of materials, energy saving and environmental protection, simple equipment operation, good controllability, advanced technology.

microwave sterilization can be divided into post-packaging sterilization and pre-packaging sterilization. Packaging containers can not be made of metal materials, medium materials are needed, generally plastic soft packaging or glass, engineering plastic containers are appropriate. In order to prevent bag swelling in microwave sterilization process, the equipment can apply pressure in the working bin to adopt back pressure sterilization process, which can prevent bag swelling loss.

Now microwave sterilization technology has been extended to industrial microwave heating equipment for manufacturing industrial production to meet the needs of food cooking and processing, sterilization and freshness preservation in food processing industry; rubber vulcanization, regenerated rubber desulfurization; textile dyeing and fixing; chemical fiber product stereotyping, drying and dehydration; fur, paper and cosmetics drying and sterilization; film drying. Drying and dehydration; Tobacco curing; Drying and sterilization of Chinese patent medicinal materials or products; Solidification and drying of sand moulds, heating of graphite materials and ceramics, etc.
