Principles:

1. heat source pass through the sealed jacket

2. the heat will be transmitted to the raw material to be dried through inner shell

3. under driving of power, the tank is rotated slowly and the raw material inside it is mixed continuously. then the purpose of reinforced drying can realized

4. the material is at a vacuum state, the drop of steam jpressure makes the moisture at the surface of raw material become saturation and will evaporate

5. the solvent will be discharged through vacuum pump

6. the inner moisture of raw material will infiltrate, evaporate and discharge continuously. these three processes are carried continuously and the purpose of drying can be realized within a short time

Main Applications:

It is suitable for the raw materials that need to concentrate, mix and dry at low temperature(eg. biochemistry products in chemical, pharmaceutical and foodstuff indusries).

1.  materials that are easy to oxidize

2.  materials that are easy to volatilize

3.  materials that having strong heat sensitive or toxic

4.  materials that should not destroy its crystal in drying
