Working Principle

Introduce the heat source (for example, hot water, low pressure steam or thermal oil) to the sealed jacket, and the heat will be transmitted to the material through the inner shell;

The driving force makes the tank rotate slowly to mix the raw material in it continuously and achieve reinforced drying;

Then the material is in vacuum. The steam pressure drops, making the moisture (solvent) on the surface of raw material reach saturation and evaporate. The solvent will then be discharged in time through vacuum pump for recovery. The inner moisture (solvent) of raw material infiltrates, evaporates and discharges to the surface continuously so that the material can be dried within a short time.

Characteristics

The automatic constant temperature control system is used for heating with oil. The dryer machine can be used for drying biochemical products and mineral materials with the temperature adjusted in the range of 20-160℃.

Its heat efficiency is over 2 times higher than the ordinal dryers.

The indirect heating will not cause pollution to the material, which is in conformity with the requirements of GMP.

The equipment features easy operation, maintenance and cleaning.

Recommended technique demonstration is the solvent recovery technique arrangement.

Material to be dried

It is suitable for the concentration, mixing and drying of powdery, granular materials and fiber in chemical, pharmaceutical and foodstuff industries and the materials (like biochemical products) that require low temperature drying. Particularly it is suitable for the raw materials that are heat-sensitive, strong excitant, toxic, easy to be oxidized and volatilized, and those whose crystal can not be destroyed in the drying process.
