3 cubic rake dryer

The dried object is added from the middle of the shell. Under the continuous positive and negative rotation of the rake teeth, the material moves back and forth in axial direction, and the surface contacting the inner wall of the shell is constantly updated. It is indirectly heated by steam, evenly stirred by the rake teeth, and crushed by the grinding rod, so that the moisture on the surface of the material is discharged more favorable. The vaporized water passes through the dry dust collector, the wet dust collector and the condenser Vent from the vacuum pump outlet. Materials suitable for rake dryer: materials below 100 mesh, pigment, mud head material, soda detergent, alkali stone starch, dye pigment, clay ash, etc. The heat transfer surface is large and the thermal efficiency is high. It is especially suitable for drying heat sensitive materials. The dried materials are slurry, paste, granular, powder or fiber, and are widely used in the production process of solid sodium alcohol. Mixing is set to make the material form a continuous circulation state in the cylinder, which further improves the material heating uniformity. [1]
