Description
Technical Field

Background
The freeze dryer is originated from the vacuum freeze drying technology in the 20 th of the 19 th century, and enters the 21 st century, and the vacuum freeze drying technology is widely applied to the fields except for the fields of medicines, biological products, foods, blood products and active substances. The basic principle of freeze-drying is based on the tri-state change of water. The water has solid state, liquid state and gaseous state, and the three states can be mutually converted and coexist. When water is at the triple point (temperature of 0.01 ℃ C., water vapor pressure of 610.5Pa), water, ice and water vapor can coexist and balance each other. Under the high vacuum state, the sublimation principle is utilized, so that the moisture in the pre-frozen material is directly sublimated into water vapor in the ice state without melting the ice, and the water vapor is removed, thereby achieving the aim of freeze drying.
The vacuum pump is a device or equipment for obtaining vacuum by pumping a pumped container by using a mechanical, physical, chemical or physicochemical method. In general, a vacuum pump is a device for improving, generating and maintaining a vacuum in a certain closed space by various methods.
In the production activity, when the vacuum pump vacuumizes, some internal material moisture can be absorbed from the freeze-drying bin, the oil in the vacuum pump can be emulsified and cannot be used, and the production operation activity is influenced.
