1.-Vacuum freeze dryer2.Compared with the heating drying method, freeze drying has many advantages, such as low volatile loss, no preservative, keeping the active ingredients in the material. Therefore, freeze-drying technology is widely used in pharmaceutical, food, scientific research and other fields.
3.Generally speaking, freeze-drying machine is mainly composed of refrigeration system, vacuum system, heating system and control system.
2.-Main Features
*Protects many heat sensitive substances in the materials.
*When drying at low temperature, the loss of some volatile components in the materials is very small.
*In the freeze-drying process, the growth of microorganisms and the role of enzymes can not be carried out.
*The volume is almost unchanged and the original structure is maintained.
*The surface hardening of the material will not be caused because the moisture in the material exists in the form of ice crystal after freeze drying.
*The materials is loose, porous and spongy after freezing dried, so can dissolve quickly and completely, and almost immediately returns to its original shape.
*Since drying is carried out under vacuum, there is little oxygen, so some easily oxidized substances are protected.
*Freeze drying can remove more than 95% ~ 99% of moisture, so that the dried products can be preserved for a long time without deterioration.
*Because the material is in the freezing state and the temperature is very low, so the requirement of heat source is not high.
