Disc drying machine

A disc drying machine is a type of equipment commonly used in industrial settings to dry or remove moisture from various materials. It consists of a rotating disc or a series of discs arranged in a stack, and the material to be dried is typically fed onto the discs.

The working principle of a disc drying machine involves the application of heat and the use of a large surface area to facilitate the evaporation of moisture from the material. Here's a general overview of how it operates:

Material feeding: The wet or moist material is fed onto the rotating discs. The discs are usually perforated or have some form of surface texture to enhance the drying process.

Heat transfer: Heat is supplied to the disc drying machine, typically through direct contact with hot air or by utilizing steam or thermal oil as a heating medium. The heat source raises the temperature of the discs, transferring thermal energy to the material.

Drying process: As the material comes into contact with the heated discs, the moisture within it starts to evaporate. The high surface area of the discs facilitates rapid evaporation, allowing the moisture to be released into the surrounding environment.

Moisture removal: The evaporated moisture is typically removed from the drying chamber using exhaust fans or other ventilation systems. This helps maintain a controlled drying environment and prevents the reabsorption of moisture by the material.

Discharge: Once the material has undergone sufficient drying, it reaches the discharge point of the disc drying machine. It can then be collected for further processing or packaging.

Disc drying machines are versatile and can be used for drying a wide range of materials, including powders, granules, slurry, and pastes. Some common applications include drying food products, pharmaceuticals, chemicals, minerals, and agricultural products.

The design and specifications of disc drying machines may vary depending on the specific requirements of the material being dried and the desired drying capacity. Factors such as disc size, disc speed, temperature control, and airflow management are considered to optimize the drying process and ensure efficient moisture removal.

It's important to note that the operation and maintenance of disc drying machines should comply with safety guidelines and manufacturer recommendations to ensure safe and effective drying operations.

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.
