Vacuum Pump Freeze Drying Technology

Vacuum pump is a device that produces, improves and maintains vacuum in a closed space by various methods. In addition to manufacturing vacuum, it also has freeze-drying technology, which is widely used in various industries, especially in the food industry.


Speaking of freeze-drying, you may first think of food, such as seafood freezing, of course, there are condiments, fruits and so on. This technology basically uses the special advantages of liquid ring vacuum pump, changes the characteristics of food itself, after vacuum drying, retains the nutrition of food, in order to facilitate easy transportation. A form of marketing in which sales are carried out in other forms. So what is the freeze-drying technology of this equipment?


Because in a long time, for the processing of food, especially seafood, manual operation is basically used, depending on seasonal changes, the efficiency is very low, but after using the liquid ring vacuum pump technology, not only the production efficiency has been improved several times, but also the quality of production has been guaranteed.

The freeze-drying technology of liquid ring vacuum pump is not only applied to food processing, but also to some vaccines and medicines produced by pharmaceutical factories. It is also used to preserve organisms in the medical industry, which has achieved very good results and has become a more practical vacuum equipment in recent years. This process is to freeze the material before vacuum, when the material has been frozen into ice water sublimation after removal, so the freeze-dried material will remain in its original state. This technology has been developed in China for decades, and its design is quite mature, which has made great contributions to many industries.


Vacuum pump freeze-drying technology is mainly used in the food industry, which contributes to food preservation and shelf life extension. In the food industry, it can not only make vacuum to keep food from decaying, but also play an important role in food preservation through freeze-drying technology.
