Freeze drying machine
Freeze dryer is a device that directly sublimates solid water (ice) in an object into water vapor under vacuum conditions, removes it from the object, and dries it The vacuum freeze-drying technology used in freeze dryers has a wide range of applications in fields such as biotechnology, pharmaceutical industry, materials science, and deep processing of agricultural and sideline products

Double stage rotary vane pumpApplied to freeze-drying equipment
A freeze-drying machine consists of five parts: a drying box, a heating system, a vacuum system, a refrigeration system, and a control system Among them, the vacuum system of the vacuum freeze dryer must be able to remove water vapor, and according to the requirements of the freeze dryer process, the maximum vacuum degree of the pharmaceutical freeze dryer under no load needs to reach 1Pa, and the maximum vacuum degree of the food freeze dryer under no load needs to reach 10Pa Therefore, it is necessary to use a rotary vane pump with fast pumping capability, such as Shanghai Bodong PfeifferRotary vane oil pumpVacuum degree of 10-3 hPa, sturdy and durable, suitable for all medium and low vacuum applications, widely used in the vacuum system of freeze-drying machines
