Vacuum dryer is widely used in pharmaceutical, chemical, foodstuff and electronic industries.
Principle of work
It is well known that vacuum drying is to put raw material into the environment of vacuum for heating and drying. If use vacuum pump to draw air and humidity out, the dry 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 ZSWJ series hydraulic jet vacuum pump sets, condenser can not be used and the cost of investment could be saved.
Under the condition of vacuum, the boiling point of raw material will decrease and make the pushing force become greater. Therefore for a certain amount of heat radiation, the conducting area of evaporator can be saved;
The heat source for operation of evaporation may be Iow pressure steam or surplus heat steam;
The heat loss of evaporator is little;
Before drying, the treatment of disinfection can be carried out. During the period of drying, there is no impurity material mixed in. It is in conformity with the requirement of GMP;
It belongs to static drier. So the shape of raw material to be dried will not be destroyed.
