FAQ:

1. What is the working principle of the freeze dryer?

Vacuum freeze-drying is to freeze the material below the eutectic point temperature, so that the water in the material becomes solid ice, and then under a proper vacuum degree, the ice is directly sublimated into water vapor. Then use the water vapor condenser (water trap) in the vacuum system to condense the water vapor to obtain the technology of drying products.

2. What are the supporting equipment of the freeze dryer?

Circulating water vacuum pump, diaphragm vacuum pump.

3. What is the reason why the vacuum degree of the freeze dryer cannot drop?

The temperature of the pump is too high. It is likely that the pump casing or inner wall of the vacuum freeze dryer pump is worn out, and the motor rotor pivot is offset, causing damage to both sides. Or the air inlet filter is blocked.
