Hollow paddle dryers have been successfully used in food, chemical, petrochemical, dye, industrial sludge and other fields. The characteristics of heat transfer, cooling and stirring of the equipment make it possible to complete the following unit operations: combustion (low temperature), cooling, drying (solvent recovery) heating (melting), reaction and sterilization. The stirring blade is also a heat transfer surface, which increases the heat transfer area per unit of effective volume and shortens the processing time. The heat transfer surface of the wedge-shaped blade has a self-cleaning function. Compression-expansion stirring function makes the material mix evenly. The material moves in a "plug flow" along the axial direction. In the axial range, the temperature, humidity and mixing degree gradient of the material is very small. Using heat transfer oil as heat medium paddle dryer can complete low temperature combustion work.
The hollow blade dryer's series of adjustable pitch propellers rotate at high speeds to keep the material unchanged, exciting contact and preventing fouling of the heat transfer walls. This paddle dryer system can range from a few hundred kilograms per hour to many tons per hour. For heat-sensitive materials, short residence times provide fast, efficient drying while maintaining temperature control of your product.
