Features of Spray Dryer
1. The product has good uniformity, fluidity and solubility, high purity and good quality. The production process is simplified and the operation and control are convenient.
2. It can be dried into powder products at one time, without crushing and screening after drying, reducing the production process and improving product purity.
3. The drying speed is fast, the surface area of the material liquid is greatly increased after atomization, and 95%-98% of the water can be evaporated in an instant in the hot air flow, and the drying time is only a few seconds, especially suitable for drying heat-sensitive materials.
Principle of Spray Dryer
After being filtered and heated, the air enters the air distributor on the top of the dryer, and the hot air enters the drying chamber evenly in a spiral shape.
The feed liquid passes through the high-speed centrifugal atomizer on the top of the tower, (rotating) and sprays into very fine mist droplets, which can be dried into finished products in a very short time in contact 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 evacuated by the induced draft fan.
