1 Heat energy (such as hot water, low pressure steam or heat conduction oil) is passed through the airtight interlayer, and the heat is transmitted to the dried material by the inner shell.
2 under the Power Drive, the tank is rotated slowly, the material in the tank is mixed continuously, thus the purpose of strengthening drying is achieved.
3 The material is in a vacuum state, the vapor pressure drop causes the material surface moisture (solvent) to reach the saturation and evaporates, and by the vacuum pump promptly discharges the recovery. Material internal moisture (solvent) continuously to the surface infiltration, evaporation, discharge, three processes continue, the material in a very short time to achieve drying purposes.
