Laboratory Freeze Dryer
Laboratory freeze dryers are mainly used in biological products research and development, pharmaceutical reagents, food science material science and other fields, generally with small size, convenient operation, intelligent monitoring and other characteristics.

Freeze Dryer in Pharmaceutical Industry
Equipment is widely used in the production of various types of drugs, including biological products, chemical preparations and herbal extracts, freeze-drying technology can better protect the active ingredients of drugs, reduce heat loss of heat-sensitive drugs, and improve the stability and storage time of drugs.

Drying Process of Vacuum Freeze Drying Equipment

Pre Freezing
The first step in freeze-drying is pre freezing. By pre freezing the free water in the sample, irreversible changes such as foaming, concentration, shrinkage, and solute movement will not occur during vacuum drying.

Sublimation Drying
Sublimation drying is the process of dehydrating and drying frozen products by directly sublimating their ice crystals into water vapor through vacuum pumping. This stage of drying starts from the surface of the material and gradually moves inward. When all the ice crystals are removed, this stage of drying is considered complete.

Desorption Drying
After the first stage of drying is completed, there is still some moisture adsorbed on the capillary walls and polar groups of the dried material. In order to extend the product's shelf life and storage stability, this moisture must be removed, which is the purpose of analytical drying. The temperature of the dried product should be high enough to achieve the final freeze-drying purpose.

Principle of Vacuum Freeze Drying Equipment
The basic principle of vacuum freeze-drying is to use the principle of ice crystal sublimation under vacuum and low temperature conditions, so that the moisture in the pre frozen material is directly removed as water vapor through solid-state sublimation without melting, and the material is dried under the condition of losing only pure water and almost no other substances, which is called vacuum freeze-drying.

The application range of vacuum freeze-drying technology is very wide. The food industry uses vacuum freeze-drying technology to manufacture freeze-dried products for long-term storage. It is also applied in the biopharmaceutical industry, medical industry, health product industry, etc.
