Descriptions:
It is a new generation drying device developed by our factory on the basis of combining the technology of similar equipment. Therefore it is stable in operation. The special design guarantees two shafts realize good concentricity. 

Heat medium and vacuum system all adapt reliable rotating connector with the technology from USA. It can carry out steeples speed change and constant temperature control.

Principle:
Let heat source, for example, low pressure steam or thermal oil pass through the sealed jacket. The heat will be transmitted to raw material to be dried through inner shell. 

Under driving of power, the tank is rotated slowly and the raw material inside it is mixed continuously. The purpose of reinforced drying can be realized; 
The raw material is under vacuum. The drop of steam pressure makes the moisture at the surface of raw material become saturation and will evaporate. The solvent will be discharged through vacuum pump and recovered in time. The inner moisture of raw material will infiltrate, evaporate and discharge continuously. The three processes are carried out unceasingly and the purpose of drying can be realized within a short time.
