Double Cone Vacuum Dryer

Heat energy (hot water, low-pressure steam or heat transfer oil) is introduced into the closed interlayer, and the heat is transferred to the dried material through the inner shell. Driven by power, the tank body rotates slowly, the materials in the tank are constantly turned and mixed, and the heat is received from the inner surface of the wall, so as to achieve the purpose of strengthening drying. The material is in a vacuum state, and the vapor pressure drops to make the water (solvent) on the surface of the material reach a saturated state and evaporate, and is discharged and recovered by a vacuum pump in time. The moisture (solvent) inside the material continuously penetrates, evaporates and discharges to the surface. The three processes are carried out continuously, and the material achieves the purpose of drying in a short time.
