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.
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
