The vacuum freeze dryer is a core equipment that relies on the “freezing – vacuum sublimation” technology to achieve efficient dehydration and preservation of heat – sensitive and easily oxidizable materials. It is widely used in fields such as pharmaceuticals, food, and biotechnology.
The main body of the equipment is made of food-grade/medical-grade stainless steel, which has both corrosion resistance and hygiene, fully meeting the high cleanliness requirements of production scenarios in pharmaceuticals, food, and other fields. The core consists of a refrigeration system (quickly freezes materials into a solid state to lock in biological activity and nutrients), a vacuum system (creates a low-pressure environment to make ice sublimate directly into water vapor), a heating system (precisely provides heat for the sublimation process to accelerate drying), and a condensation water capture system (efficiently captures sublimated water vapor to ensure drying efficiency).
Equipped with visual observation window (for real-time monitoring of the drying status of materials inside the chamber), sealed vacuum chamber (to ensure a stable vacuum environment and facilitate the sublimation process), and featuring intelligent control system, it can precisely regulate key parameters such as temperature, vacuum degree, and drying duration, realizing full-process automation from “material freezing → sublimation drying → finished product output” without frequent manual intervention.
