  Vacuum freeze-drying technology is widely applied in biological engineering, pharmaceutical industry, food industry, materials science and deep processing of agricultural and sideline products.

  Freeze-drying is a technology through the use of the principle of sublimatio for drying, is to achieve rapid freezing of the material in low temperature , and then in a suitable vacuum environment the frozen water molecules will be directly sublimated into water vapor and then escape.The product obtained by drying is called lyophilisate and this process is called lyophilisation.

  The material is always in the low temperature (frozen state) before drying, and the ice crystals are evenly distributed in the material. The sublimation process will not be concentrated due to dehydration, thus avoiding side effects such as foam and oxidation caused by water vapor. Dry matter was dry sponge porous, the volume is basically the same, very easy to dissolve in water and restitution. To the greatest extent to prevent physical and chemical and biological aspects of denaturation.

  The freeze dryer is composed of a refrigeration system, a vacuum system, a heating system and an electrical instrumentation control system. The main components is oven, condenser, refrigeration units, vacuum pumps, heating / cooling devices. Its working principle is to make the material be frozen below a certain temperature, and then under the conditions of the vacuum the solid state of the water (ice) is directly sublimated into water vapor and discharged out to get dry items.
