Environmental requirements for small freeze dryer use

The vacuum freeze dryer is referred to as freeze dryer, and its components mainly include drying box, water vapor condenser, refrigeration system, vacuum system, heating system, control system, etc. According to the freeze drying area of the freeze dryer, it can be divided into laboratory freeze dryer, pilot freeze dryer and production freeze dryer.

Environmental requirements for the use of small freeze dryer:

1. Normal working conditions:

Ambient temperature: 10℃～30℃

Relative humidity: ≤70%

Power supply voltage: single-phase 220V±10% 50Hz

Working environment: it should be placed horizontally, without conductive dust, explosive, corrosive gases and strong electromagnetic field interference.

2. Transportation and storage conditions:

Ambient temperature: -35℃～50℃

Relative humidity: ≤93%

Storage environment: it should be well ventilated and free of corrosive gases.

Freeze dryers are widely used in the fields of medicine, pharmaceuticals, biological research, chemical industry and food. When purchasing a freeze dryer, you should pay attention to parameters such as freeze drying area, cold trap temperature, cooling rate, ultimate vacuum degree, vacuum pumping time, and control system.
