Working 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 (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. The three processes are carried out unceasingly and the purpose of drying can be realized within a short time.

Characteristics

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 20-160℃.
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.

Application scope

It is suitable for concentration, mixing and drying of powder, granule and fiber in chemical industry, pharmaceutical industry and food industry, as well as materials (such as biochemical products) that need to be dried at low temperature. It is also suitable for drying of easily oxidized, volatile, heat sensitive, strongly irritating, toxic materials and materials that are not allowed to destroy crystals.
