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.
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
The heat source for evaporation may be low pressure steam or surplus heat steam. The heat loss is less.
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 will be kept well.
