● Heat source (for example, low pressure steam or thermal conduct oil) passthrough the sealed jacket. The heat will be transmitted to raw material to bedried through inner shell;
● Under driving of power, the tank is rotated slowly and the raw material inside itis mixed continuously. The purpose of reinforced drying can be realized;
● The raw material exists is under vacuum. The drop of steam pressure makesthe moisture (solvent) at the surface of raw material become saturation and willevaporate. The solvent will be discharged through vacuum pump an recoveredin time. The inner moisture (solvent) of raw material will infiltrate, evaporate anddischarge continuously. The three processes are carried out unceasingly andthe purpose of drying can be realized within a short time.
The mesh-belt dryer is a common continuous dryer equipment, it is widely applied in chemical, foodstuff, pharmacy, construction material, and electronic industry, and particularly it is adapt to dry the raw materials which have good air permeability and shaped in sheet, strip or granule. For ointment stuff, the wisest way to dry it are: shaped those stuff first, then drying it.
