VACUUM TRAY DRYER

YZG/FZG SERIES VACUUM DRIER

Applications:
The vacuum tray dryer is suitable for drying heat sensitive raw materials that can decompose and polymerize and metamorphose at high temperature. It is wide used in pharmaceutical, chemical, foodstuff and electronic industries.

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.
Note: if use condensate, the solvent in raw material can be recovered. If use SK series water drying vacuum pump sets, condensate can not be used and the investment could be saved.

Features:
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 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 disinfections may be carried out. During the period of drying, there is no impurity material mixing. It is conformity with the requirement of GMP.
It belong to static drier. So the shape of raw material to be dried can not be destroyed.
