Condiments 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.
▪ Energy saving and efficiency: Microwave drying materials directly, furnace air and container are not heating, so no energy loss, high th- ermal efficiency, compared with traditional drying equipment, energy efficiency can be increased by more than 30%;
▪ Fresh and mildew proof: Microwave has thermal effect and biologi- cal effect, can effectively kill bacteria and mold in the material, effe- ctively prolong the food fresh life and shelf life;
▪ Clean and hygienic: Different from traditional drying equipment, mi- crowave drying does not need heating medium, direct action on ma- terials, and processed the process has no waste water, no waste gas, clean sanitation and no pollution.
▪ Easy to operate: The equipment adopts PLC program control, vis- ual man-machine operation interface, simple and clear operation,namely use.
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.
