High-Efficiency Disc Dryer

This disc dryer is a continuous conduction heating drying equipment, with the core working component being multiple layers of alternately rotating hollow heating discs. After the materials enter the equipment through the top feed port, they are evenly distributed along the surface of the disc and continuously flipped under the action of the rotating rake blades. At the same time, they undergo thorough heat exchange with the high-temperature heat medium introduced into the inner cavity of the disc. The moisture rapidly vaporizes and is discharged by the exhaust system at the top of the equipment. The final dried products are continuously discharged from the bottom discharge port. The equipment adopts a fully enclosed structure design, with high heat medium utilization efficiency and can be completely dried Flexibly adjust the disc temperature, rotational speed and material residence time according to the material characteristics, to meet the drying requirements of various forms of materials ranging from paste, granular to powder.

High efficiency and energy saving, with high heat utilization rate: It adopts conduction heating method, and the heat is directly transferred to the material through the heating disc, avoiding the large amount of heat loss carried away by the hot air in traditional hot air drying. The heat utilization rate can reach over 70%, and it saves 30% to 50% energy compared with hot air drying equipment. Meanwhile, the fully sealed structure reduces heat leakage and further enhances energy utilization efficiency.
Uniform drying and superior product quality: The multi-layer alternately rotating discs, in combination with the dedicated rotating rake blades, can evenly spread the material on the disc surface and constantly turn it over, ensuring that each grain of material can fully contact the heating surface. After drying, the moisture content of the material is uniform, without local overheating or incomplete drying, effectively maintaining the original physical and chemical properties of the material. It is especially suitable for heat-sensitive materials.
It has a wide range of applications and is compatible with various types of materials: it can handle materials in various forms such as paste, filter cake, granules, and powder. The moisture content of the feed can range from 35% to 70%. By adjusting the disc temperature (50℃-220℃), equipment speed, and material residence time, it can meet the drying requirements of materials in different industries. Multi-variety production can be achieved without replacing the equipment.
Stable operation and high degree of automation: Equipped with an intelligent control system, it can precisely regulate parameters such as feed rate, disc temperature, rotational speed, and exhaust humidity, supporting continuous production and reducing manual intervention. The equipment operates stably and reliably with a low failure rate. It is also equipped with safety devices such as overload protection and temperature alarm to ensure production safety.
