Vacuum pump related to refrigeration and drying applications
With the development of economy, the application of water-ring vacuum pump in production and daily life has been more and more extensive. It was used as self-suction pump initially, and gradually developed to many industrial sectors such as petroleum, machinery, chemical industry, mining, medicine, light industry and food. This is mainly about the application of water ring vacuum pump on refrigeration and drying.
When it comes to freeze-drying, people may think of food first, such as condiments, fruits and so on, of course, there are also seafood freezing, this technology is basically the use of water ring vacuum pump special advantages, change the characteristics of food itself, after vacuum drying to retain the nutrition of food, in order to facilitate easy transportation A form of market selling in other forms.
Because in the ancient times for food, especially seafood processing, most of the use of manual operation, but also depends on seasonal changes, the efficiency is very low, but the use of water ring vacuum pump this process, not only the production efficiency has increased many times, but also the quality of production has been guaranteed.

This freeze-drying technology of water-ring vacuum pump is not only used in food processing, but also has the same effect on some vaccines and drugs produced by pharmaceutical factories. It is also used in the biological preservation of medical industry, thus achieving very good results and becoming 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 after the sublimation of water, so the freeze-dried material will remain the original state. This process has been developed for several decades in China, and the design is quite mature. It has made great contributions to many industries.
In fact, the application of water ring vacuum pump in refrigeration and drying is very extensive, and it has been used in all walks of life, and the prospect is very wide.
