It is well known that vacuum drying is to put raw material heating and drying under vacuum condition . It adopt vacuum pump to take air and humidity out,make chamber form vacuum state. In the drying chamber, material will be dried under vacuum condition.

Under the vacuum condition, the boiling point of material solution will reduce. It will increase impetus for heat and mass exchange. Therefore for certain heat exchange amount, it can save heat exchange area of evaporator. Material is under static condition during operation of the equipment, which is benefit for keeping initial status of material. Intermittent operation can adjust process conditions at any time.On the top of Square vacuum dryer, heating system is arranged to tackle the problem of return of condensed water, in addition, air suction is arranged at the side to improve drying efficiency.the boiling point of water is reduced to accelerate the drying speed.

Features

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. heat source of vacuum dryer are: electric, steam, hot water, heat transfer oils for buyer to choose.

3.Before 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.

4.It’s static dryer. So the shape of raw material to be dried should not be destroyed.

5.It is suitable for materials such as heat sensitive and easy oxidizable material.

6.The machine is a kind of batch type operation and can adjust technical process at any time.

7. The inner top is designed arch structure, it can effectively avoid the condensed water drop back.

8. Vacuumize from 4 points to one point which can guarantee uniform drying.
