Food Microwave Drying Sterilizing

Food Microwave Drying Sterilizing

▪ Fast and uniform: Microwave irradiation to the material, the material   inside and outside heating at the same time, saving the traditional   drying preheating process, material heating up quickly, 3-5 minutes   to complete the drying of the material, while avoiding the traditional   equipment drying materials inside and outside temperature differe-  nce, making the drying effect is more uniform.

 ▪ Advanced technology: Equipment adopts advanced tunnel structure  feeding and discharging synchronously, convenient for continuous   production, with various from dynamic production equipment, can   realize flow production mode, greatly saving labor cost. 

▪ Keep fresh fragrance: Compared with the traditional thermal drying,   microwave can penetrate the material in a very short time to complete   the drying operation of the material. It can better retain the nutrition   composition and color, aroma, taste, shape and other characteristics   of the food, maintain the freshness of the food, taste better. 

▪ Simple operation: The equipment adopts PLC program control, vi-  sual man-machine operation interface, simple and clear operation,   namely out-of-the-box; 

▪ Extended maturity: Microwave has thermal effect and biological eff-  ect, can effectively kill the bacteria in the material, mold, effectively   extend the freshness and shelf life of food.

Principle of Microwave Sterilization Drying

Microwave sterilization is the result of the combination of thermal and biological effects of electromagnetic fields. The  thermal effect of microwaves to bacteria is to make proteins change, causing bacteria to lose nutrients, reproduce and  survive conditions. The biological effect of microwave on the bacteria is microwave electric field change in the cross section  of the cell membrane potential distribution, influence the membrane surrounding electrons and ions concentration, which  change the membrane performance, fully bacteria so malnutrition, cannot normal metabolism, cell structure function disorder,  growth is restrained and death. In addition, the microwave can make normal bacteria growth and stable genetic breeding of  nucleic acid RNA and DNA, DNA is made up of a number of hydrogen bonding is flabby, faults and restructuring, and thus  induce genetic mutations, or chromosome aberration and even rupture.
