Features：

● Under the condition of vacuum, the boiling point of raw material will decrease and make the evaporation efficiency higher. Therefore for a certain amount of heat transfer, the conducting area of dryer can be saved.

● The heat source for evaporation may be low pressure steam or surplus heat steam.

● The heat loss is less.

● Before drying, the treatment of disinfection may be carried out. During the period of drying, there is no impurity material mixed. It is in conformity with the requirement of GMP.

● It belongs to static dryer. So the shape of raw material to be dried should not be destroyed.

Principle：

    It is well known that vacuum drying is to put raw material under the state of vacuum for heating and drying. If use vacuum to pump air and humidity out, the dry speed will be faster. Note: if use condenser, the solvent in raw material can be recovered. If apply SK series water ring vacuum pump, condenser might be canceled and the investment and every could be saved.

Application：

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