1.Let heating 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.
2. 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.
3. The raw material is under vacuum. The drop of steam pressure makes the moisture (solvent) 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(solvent)of raw material will infiltrate,evaporate and discharge continuously
4. The three processes are carried out unceasingly and the purpose of drying can be realized within a short time.
When oil is used to heat,use automatic constant temperature control. It can be used for drying biology products and mine its temperature of operation can be adjusted form 20º C-160º C and within ± 2º C .
Compared to ordinal dryer, its heat efficiency will be 2 times higher.
The heat is indirect. So the raw material can not be polluted.
It is in conformity with the requirement of GMP. It is easy in washing and maintenance.
