Spray drying is the most widely used process in liquid process formation and drying industries. It is most suitable for producing powdered and granular solid products from solution, lotion, suspension, and paste-like liquid raw materials. Therefore, when the particle size distribution, residual moisture content, bulk density, and particle shape of the finished product must meet precise standards, spray drying is an ideal process.

The air, after being filtered and heated, enters the air distributor at the top of the dryer, and the hot air spirals uniformly into the drying chamber. The material liquid passes through the high-speed centrifugal atomizer at the top of the tower, (rotating) sprayed into extremely fine mist-like droplets, which come into contact with the hot air in parallel flow and can be dried into finished products in a very short time. The finished products are continuously output from the bottom of the drying tower and the cyclone separator, while the exhaust gas is vented by the fan.

With a fast drying speed, the material liquid, after being atomized, greatly increases its surface area. In the hot airflow, 95%-98% of the water can be evaporated instantly, and the drying time is only a few seconds. It is especially suitable for drying heat-sensitive materials.
The product exhibits good uniformity, fluidity, and solubility, with high purity and excellent quality.
The production process is simplified, and operation control is convenient. For liquids with a moisture content of 40-60% (up to 90% for special materials), they can be dried into powder products in one go. After drying, there is no need for crushing and screening, reducing production steps and improving product purity. The particle size, bulk density, and moisture content of the product can be adjusted within a certain range by changing operating conditions, making control and management very convenient.

Food, medicine, chemical industry, dyeing and chemical industry, ceramics, biochemistry, pesticides, plastics, etc. are suitable for liquids with corresponding fluidity.
