Spray drying is a widely used process in the liquid forming and drying industry. It is suitable for producing powdered and granular solid products from solutions, suspensions, and pasty liquid raw materials. Therefore, when the particle size distribution, residual moisture content, bulk density, and particle shape of the finished product must meet the standards, spray drying is an ideal process.

Air is filtered and heated, then enters the top air distributor of the drier, where it uniformly spirals into the drying chamber. The liquid material is sprayed into an extremely fine mist by a high-speed centrifugal atomizer at the top of the tower (rotating), forming mist-like droplets. The product can be dried into finished goods through concurrent contact with hot air in a very short time. The finished goods are continuously discharged from the bottom of the drying tower and the cyclone separator, while the exhaust gas is exhausted by the fan.

Fast drying speed; after atomization, the surface area of the liquid material is significantly increased. In the hot air stream, 95%-98% of the moisture can be evaporated instantly, and the drying process is completed in just a few seconds, particularly suitable for drying heat-sensitive materials.

The product boasts excellent uniformity, fluidity, and solubility with high purity and quality. The production process is simplified and operation control is convenient. Liquids with moisture content of 40-60% (special materials up to 90%) can be dried into powdered particles in one step, eliminating the need for crushing and sieving, reducing production steps, and enhancing product purity. Particle size, bulk density, and moisture content can be adjusted within a certain range by modifying operating conditions, making control and management easy.
