application area:
Logistics, biology, medicine, chemistry, pathology, zoology, forensic identification, food health products, archaeology, printing, geology and so on.
Application scope:
It is suitable for freeze drying of bacteria, virus plasma, serum, antibody, vaccine, medicine, microorganism, yeast, cosmetics, health products, Chinese herbal medicine, chemical and biological research plant extraction.
Application principle:
Vacuum freeze-drying is a technique using the principle of sublimation to dry. It is a process that freezes the dry matter at low temperature and then directly sublimate the frozen water molecules into the vapour escape under the vacuum environment in use. The freeze drying product is called the freeze-dried substance (Lyophilizer). This process is called the process known as the freeze-drying. Freeze-dried (lyophilization). Before drying, the material is always at low temperature (freezing state), and the ice crystal is evenly distributed in the substance. The distillation process will not be concentrated because of dehydration. It avoids the side effects of water vapour producing foam and oxidation. The dry matter is porous with dry sponge, the volume is basically unchanged and it easily dissolves in water and is easily restored to the original form. To prevent physical and biological variability of dry matter to a maximum extent.
