Spray dryer Germany India Japan
Spray drying equipment is the most widely used machine in the liquid process forming and drying industry. Spray drying equipment is used to produce powdery and granular solid products from solutions, emulsions, 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 precise standards, spray drying is a very ideal process.
After filtering and heating, 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 material liquid passes through the high-speed centrifugal atomizer at the top of the tower, and (rotating) sprays into very fine misty liquid beads, which can be dried into finished products in a very short time in co-current 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 fan.
Experimental spray dryer equipment parameters:
1. Moisture evaporation rate 1000-1500ml/hour
