Hollow paddle dryer is a kind of high-efficiency, energy-saving and environmentally friendly drying equipment, which is suitable for the drying treatment of a variety of materials. The working principle of the hollow paddle dryer is to send the hot air into the dryer after heating through the preheating device, contact with the wet material, and use the heat transfer method to transfer the heat to the material, so that the temperature of the material increases. At the same time, the high-speed rotating paddle drives the wet material to form a thin layer of wet material, which is quickly blown away by the hot air. In this process, the water on the surface of the material evaporates and escapes from the surface of the material through mass transfer, so as to achieve rapid drying of the material.
The advantages of hollow paddle dryer lie in its high efficiency, energy saving and environmental protection. It can meet the drying needs of different materials, such as calcium nitrate, calcium sulfate, calcium papermaking, calcium carbonate, magnesium hydroxide, carbon black, iron black, iron red, soda ash, soda ash, etc. in the inorganic chemical industryDyes in the organic chemical industry, industrial plastics, polystyrene, polypropylene, high and low density polyethylene, polypropylene, etc.;Nickel concentrate powder, sulfur concentrate powder, tar dephenolization in the smelting industry, etc.;Starch, medicine, salt, protein, etc. in the food and medical industries, as well as other such as sludge, waste residue, chicken feed, distiller's grains, etc.
When selecting and using a hollow paddle dryer, there are various factors to consider, including the nature of the material, the output and the drying requirements. At the same time, correct use and maintenance can prolong the service life of the equipment, improve the efficiency of the equipment, and reduce costs.
Overall, the hollow paddle dryer is a very versatile and efficient drying equipment, which is suitable for the drying of various industries and materials.
