Rotary Vane Vacuum Pump and Liquid Ring Vacuum Pump are two common types of vacuum pumps. They have some differences in terms of working principle, application fields, advantages and disadvantages, etc.
The vacuum pump is the core component of a freeze dryer. It continuously removes gas and water vapor from the chamber, creating and maintaining a high-vacuum, low-temperature, low-pressure environment. This ensures that ice crystals in the material can directly sublimate, providing crucial power for achieving efficient and stable freeze-drying processes. Its performance directly affects freeze-drying efficiency and product quality.
A vacuum pump refers to a device or device that uses mechanical, physical, chemical or physicochemical methods to evacuate the evacuated container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a certain closed space.
