Different Shapes And Different Purposes ,High Speed Centrifugal Atomizer Spray Dryers
Industrial spray dryer
1. Description of spray dryer machine
After fresh air is filtered and heated, it enters into the air distributor which on the top of the drier. The hot air in spiral form equably enters into the drying room. When liquid raw material are passed through the high-speed centrifugal sprayer on the top of the tower, it will be rotated and sprayed into the extreme slim mist liquid beads. Raw material can be dried to the final products instantly while it contact with the heatedair. Finished products are discharged continuously from bottom of the drying tower and cyclones segregator. Wasted air is discharged from blower.

Product Features
High speed drying:the surface area of liquid material is greatly increased after atomization, achieving instantaneous evaporation of 95% -98% water in the hot air flow, drying time only takes a few seconds, especially for heat-sensitive materials
Products achieve good uniformity, mobility and solubility, and also achieve purity, good quality. The production process is simplified and the operation control is convenient. For liquid materials with the moisture content of 40-60% (special materials up to 90%) can be dried into powder products just with one time, do not need grinding and screening after drying, reduce production processes and improve product purity. The product size, bulk density, moisture, in a certain range can be adjusted by changing operating conditions, control and management are very convenient.
The air is filtered and heated into the top air distributor of the dryer, and the hot air enters the drying chamber evenly in a spiral fashion. The material liquid is sprayed into a fine atomized liquid droplet through the high-speed centrifugal nebulizer at the top of the tower body, and can be contacted with the hot air in a very short time and can be dried into finished products. The finished product is continuously discharged from the bottom of the drying tower and the cyclone, and the exhaust gas is drained by the draft fan.
