Spray dryer is a kind of continuous atmospheric pressure dryer. Spray the liquid material into a mist using special equipment, allowing it to come into contact with hot air and be dried. Used for drying some thermosensitive liquids, suspensions, and viscous liquids, such as milk, eggs, tannins, and drugs. It is also used for drying fuels, intermediates, soap powder, and inorganic salts.

The air is filtered and heated before entering the top air distributor of the dryer, and the hot air enters the drying chamber uniformly in a spiral shape. The feed liquid passes through the high-speed centrifugal atomizer at the top of the tower body, and (rotating) spray into fine mist like liquid beads, which can be dried into finished products in a short time in parallel with hot air. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged by the induced draft fan.

The drying speed is fast, and the surface area of the material liquid greatly increases after atomization. In the hot air flow, 95% -98% of the water can be evaporated instantly, and the drying time is only a few seconds. It is particularly suitable for drying thermosensitive materials.
The product has good uniformity, fluidity, and solubility, high purity, and good quality. Simplified production process and convenient operation control. 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 processes and improving product purity. The particle size, bulk density, and moisture content of the product can be adjusted within a certain range by changing the operating conditions, making control and management very convenient.
