Vacuum freeze drying technology, freeze drying for short, is to first freeze the materials containing water, and then sublimate them in vacuum.
The materials' chemical and biological characters remain unaffected after being dried by freeze drying, which maks them easy to be kept for a very long period without metamorphosing. Added with water, they can return to their initiative condition and their biological and chemical features are the same. Therefore, the Vacuum freeze drying technology is widely applied in the fields of chemical industry and biological products.

Main features:
1. With automatically re-freezing system, it adopts imported all-enclosed refrigeration unit, and can reach the temperature of lower than -80deg. C, vastly enabling its capacity of capturing water.
2. With the air guide shell, it freezes more water and distributes it more evenly.
3. It eliminates heat by wind not by water.
4. Vacuum connections of international standard, easy to uninstall and install.
5. With LED display, information about temperature and sample vacuum degree can be conveniently read.
6. Stainless-steel mesa, clean, beautiful and corrosion-resistant.
7. Stable and reliable function, easy to operate and lower noise.
