Vacuum freeze drying is called lyophilization for short ,which is a drying technology to put the wet material or solution at low temperature (-10℃——-50℃) under freezes into solid, and then make the moisture without liquid directly sublimate to gas in the vacuum (1.3 —— 13 PA), which finally make material dehydrated.

Our company has advanced vacuum freeze drying equipment, mainly for the production of biomedical sponge materials, which prepared with alginate has high hygroscopicity and good gelling properties, the performance index is excellent, and can carry a variety of active ingredients, extended its medical effect and scope of application.
