Product Description
brief introduction
Vacuum freeze dryer (freeze dryer) achieves material dehydration through low-temperature freezing and vacuum sublimation, and is widely used in fields such as food, medicine, and biological products, especially suitable for drying thermosensitive substances such as vaccines and coffee.
Working principle
1. Pre freezing: The material freezes into ice at 40 ℃~50 ℃.
2. Sublimation: In a vacuum environment, ice directly sublimates into water vapor, which is captured by a cold trap.
3. Analysis: Heat to remove residual moisture, so that the moisture content is less than 1%.
Core advantages
Preserving activity: Low temperature drying, avoiding thermal damage, good rehydration properties.
Long term storage: extremely low moisture content, long shelf life.
Efficient and energy-saving: low energy consumption, environmentally friendly, widely used in food, medicine, scientific research, etc.
