A spray dryer is a device that can dry and granulate simultaneously. According to the process requirements, the pressure, flow rate and the size of the spray hole of the feed pump can be adjusted to obtain the required spherical particles in a certain proportion. Meanwhile, the spray dryer is one of the continuous atmospheric pressure dryers. The liquid material is sprayed with special equipment to dry 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. What are the features of our spray dryer?

The drying speed of the spray dryer is fast, the surface area of the feed liquid is greatly increased after atomization, in the hot air stream, the moisture of 95%-98% can be evaporated in an instant, the drying time is only a few seconds, especially suitable for the drying of heat-sensitive materials. Spray dryer has good uniformity, fluidity and solubility, product purity, good quality. The production process is simplified and the operation and control are convenient. For the moisture content of 40-60% (special materials up to 90%) of the liquid can be dried into powder products, dry without crushing and screening, reduce the production process, improve product purity. The particle size, bulk density and moisture content of the product can be adjusted by changing the operating conditions within a certain range, which is convenient for control and management.
