Vacuum drying machine
Product Detailed
1. vacuum drying machine suitable for heat sensitive material 2. save heat transfer area 3. heat loss is less 4. meet GMP

YZG/FZG Series Vacuum Dryer

ApplicationVacuum drying machine 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 of workIt 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 condensator, the solvent in raw material can be recovered. If use SK series water ring vacuum pump or ZSWJ series hydraulic inject vacuum pump sets, condensator can not be used and the investment could be saved.

FeaturesUnder 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 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.
