DESCRIPTION
Spray dryer is a kind of continuous atmospheric dryer. The liquid material is sprayed into a mist with special equipment, and it is dried by contact with hot air. For drying some heat-sensitive liquids, suspensions and viscous liquids such as milk, eggs, tannins and pharmaceuticals. Also used for drying fuels, intermediates, soap powder and inorganic salts.
After filtering and heating, the air enters the air distributor at the top of the dryer, and the hot air enters the drying chamber uniformly in a spiral shape. The feed liquid passes through the high-speed centrifugal atomizer at the top of the tower body, and is sprayed (rotating) into extremely fine mist-like liquid droplets, which can be dried into finished products in a very short period of time in co-current contact with hot air. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the exhaust gas is evacuated by the induced draft fan.
