What is the difference between a paddle dryer and a disc paddle dryer?

The paddle dryer is a low-speed agitated dryer with a stirring paddle set inside the equipment to make the wet material fully contact the heat carrier and the hot surface under the agitation of the paddle to achieve the drying effect. The structure of the paddle dryer is generally horizontal, double shaft or four shaft. Because of its compact structure, high heat transfer efficiency, good self-cleaning performance, simple operation and control, etc., it is widely used in food, dye, petrochemical, chemical, industrial sludge and other production fields. Indirect heating or cooling of paste, granular, powder, and slurry materials can complete unit operations such as drying, cooling, heating, sterilization, reaction, and low-temperature combustion.

The disc dryer is a drying device for cake-like and granular materials that are not easy to agglomerate and adhere. This machine is used to dry cake-like and granular materials that are not easy to agglomerate and adhere after drying. Typical drying materials include: fish meal, graphite, carbon black, polyethylene powder, feed, distiller's grains, sludge, corn buds, etc.
