Rotary Disc Dryer Disc Drying Machine For Pharmaceutical Industry

The disc dryer consists of two to four intermeshing blade shafts, a W-shaped shell with a jacket, a machine base and a transmission part. The entire drying process of materials is carried out in a closed state, and organic volatile gases and odorous gases are eliminated. Send it to the exhaust gas treatment device in a closed atmosphere to avoid environmental pollution.
The dryer uses steam, hot water or thermal oil as the heating medium, and the shaft end is equipped with a rotary joint for the introduction and export of the heat medium. The heating medium is divided into two paths, and enters the jacket of the dryer shell and the inner cavity of the paddle shaft respectively. The body and the paddle shaft are heated at the same time, and the materials are heated and dried by conductive heating. The dried materials are quantitatively and continuously fed into the feeding port of the dryer by the screw feeder. The materials enter the back of the dryer and are turned and stirred by the rotation of the blades. The heating interface is constantly updated and in contact with the dryer body and blades, and is fully Heating makes the surface moisture contained in the material evaporate. At the same time, the material forms a spiral trajectory with the rotation of the blade shaft and is transported toward the discharge port. The material continues to be stirred during transportation, so that the water seeping out of the sludge continues to evaporate. Finally, the uniformly dried and qualified products are discharged from the discharge port.
