Rotary Atomizer Spray Dryer
PrincipleHot air enters into dryer in spiral form under the function of air distributor after being filtered and heated. By passing through high-speed rotary atomizer on top of tower,Website:, the liquid raw material will be sprayed into the extremely fine mist beads. Through the very short time of contacting with hot air, the liquid can be dried into final solid powder products. The final products will be discharged continuously from the bottom of drying tower and from cyclone separator. Waste tail air will be discharged from exhaust fan.Features1.High speed drying. After liquid raw material being sprayed, its’ surface area will be increased greatly. With higher drying efficiency, 95%-98% of water could be evaporated in a few seconds. Drying time is very short, it is suitable for heat sensitive raw material2.Product comes from spray dryer has very good uniformity, solubility, fluidity and purity.3.The production procedures are simple, the operation and control are easy. Liquid with the moisture contents ranges 40-60% (for some special materials, the moisture content is available at 90%) can be dried into the powder in one time. There is no need for grinding or sieving after spray drying, this simplifies operation procedures and improves product purity. Product size, bulk density, moisture content is adjustable in certain ranges.Technical ParametersItem/Parameters/ModelLPGInlet air temperature（℃）140-350 (automatically controlled)Outlet air temperature（℃）80-90Max capacity of evaporation moisture (kg/hDriving form
