The spray drying is a process widely applied in liquid technological forming and drying industry. It is most suitable for producing powder, grain or block solid products from solution, emulsion, suspension and plastic mushy liquid raw materials. Therefore, when the grain distribution, residual moisture content, accumulating density and grain form of the finished products meet the accurate standard, the spray drying is really an ideal process Features Rapid drying speed. After the liquid materials are atomized, the surface area is greatly increased. In the hot air current, 95%-98% of moisture of the materials with a moisture content of 40%-90% can be instantly evaporated. The drying time lasts only several seconds. It is especially suitable for drying heat sensitive materials The product has good evenness, fluidity and solubility, with high purification and excellent quality. The production process is simplified with convenient operation and control. The liquids with a moisture content of 40%-60% (special material my reach 90%) can be dried into powder products in one time. In addition, there is no need of smashing and sieving after drying, so the production procedures are reduced and product purity is enhanced. The product granularity, density and moisture can be adjusted with a certain range through changing the operation conditions, so control and management are very convenient.
