Features:

1, less heat loss of evaporator.

2, can be disinfected before drying, drying process without any impurities mixed in line with GMP requirements.

3, is a static vacuum dryer, so the body dry material will not be damaged.

4, the material under vacuum to reduce the boiling point of the solution, so that the evaporator heat transfer driving force increases, and therefore a certain amount of heat transfer can save evaporator heat transfer area.

5, the operation of evaporation source may be low pressure steam or surplus heat steam.

Principle:

The so-called Circular vacuum Dryer, the material is dried under vacuum at the conditions, heating and drying, if the use of vacuum pump air and humidity, is to speed up the drying rate.

Note: If using a condenser, a solvent in raw material can be recovered through the condenser; such as the use SK series water ring vacuum pump, condenser can not save energy investment.
