YZG/FZG Series Vacuum Drying machine
It is suitable for drying that can decompose or polymerize or e. It is widely used in pharmaceutical, chemical, foodstuff
It is well known that vacuum drying is to put raw material under the state of vacuum for heating and drying. If using vacuum to pump air and humidity out, the drying speed will be faster.
1 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.
2 The heat source for evaporation may be low-pressure steam or surplus heat steam.
3 The heat loss is less.
4 Before drying, the treatment of sterilization may be carried out. During the period of drying, there is no impurity material mixed.
5 It belongs to static dryer. So the shape of raw material to be dried should not be damaged.
6 It adopts the condenser which could retrieve the solvent in the material effectively.
