It is well known that vacuum drying is to put raw material to the state of vacuum for heating and drying. Use vacuum pump to suck air and humidity out, drying speed will be faster.

Note: if use condenser, the solvent in raw material can be recovered. If use SK series water ring vacuum pump or ZSW series hydraulic inject vacuum pump sets, condenser can not be used and the investment could be saved.

It is suitable for drying heat sensitive raw materials that will decompose and polymerize and metamorphose at high temperature. It is widely used in pharmaceutical, chemical, foodstuff and electronic industries.

 

 

Features

1. Under the condition of vacuum, the boiling point of raw material will decrease and could heat material more uniform.

2. Heating resource for choice: low pressure steam, heat conducting oil, electricity and hot water.

3. The heat loss of evaporator is less.

4. Before drying, the treatment of disinfection could be carried out. During the period of drying, there is no impurity material mixing. It is conformity with the requirement of GMP.

5. It belongs to static drier. So the shape of raw material to be dried will not be destroyed.
