Principle
※ It is well known that vacuum drying is to put raw material to the state of vacuum for heating and drying. If use vacuum to take air and humidity out, the dry speed will be faster
Application
※ It is suitable for drying heat sensitive materials that can decompose and polymerize and metamorphose at high temperature. It is wide used in pharmaceutical, chemical, foodstuff and electronic industries.

Feature
※ Under the condition of vacuum, the boiling point of raw material will decrease and make the pushing force become greater. Therefore for a centain amount of heat radiation, he conducting area of evaporator can be saved.
※ The heat source for operation of evaporation may be low pressure steam or surplus heat steam.
※ The heat loss of evaporator is less.
※ Before drying, the treatment of disinfection may be carried out. During the period of drying, there is no impurity material mixing. It is in conformity with the requirement of GMP.
※ It belongs to static drier. So the shape of raw material to be dried can not be destroyed.
※ If use condensate, the solvent in raw material can be recovered.
