A spray dryer is a device that can dry and granulate simultaneously. According to the process requirements can adjust the feed pump pressure, flow and the size of the spray hole. Thus, the required spherical particles with a certain size ratio can be obtained. The spray dryer uses special equipment to spray the liquid into a spray, which is dried in contact with hot air. Used to dry some heat-sensitive liquids, suspensions, and viscous liquids such as milk, eggs, tannin, and pharmaceuticals. Also used for drying fuels, intermediates, soap powder and inorganic salts. Next I will introduce the working principle of the spray dryer.
After the air is filtered and heated, it enters the air distributor on the top of the dryer, and the hot air enters the drying chamber in a spiral shape evenly. High-speed centrifugal atomizer at the top of the tower can spray the liquid into very fine mist-like droplets, which can be dried into finished products in very short time when in contact with hot air. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the waste gas is exhausted by the induced draft fan.
Above is the spray dryer principle of work, there is a need to contact us.
