After freeze drying, the product will be sealed under vacuum condition and isolate from the air completely, especially oxygen, so that the product could be stocked for long time under cryogenic temperature.
After freeze drying‘s material, EnLDmatic effect is very weak, original physical and chemical property almost don’t change, after dehydration, the material present its porosity structure, volume not changed, after adding water, could recover at once. After freeze drying, the material can be stored for several years without deterioration
Vacuum freeze-drying machine for heat-sensitive biological products such as vaccines, serums, vaccine, blood plasma, drugs and heaLDh products, food can be freeze-dried material dry.
