Brief introduction of products
A pressure below the atmospheric pressure will be maintained inside the chamber during the refrigerating vacuum drying process that leaves the gas with a less number of molecules, low density, low oxygen content to enable a reaction of disinfection and sterilization against the materials or medicines, foods and biological products that are vulnerable to oxidative deterioration; thus, the possibility for the material to be infected by the germs is lessened while the growth of bacteria is inhibited; also, the refrigerating vacuum drying method can attain the best effect amongst the multiple drying methods; that is, it can output a product with best quality from the manufacturing process while its quality is much better than other general drying methods either in color or taste, and its drying duration is the shortest one.
