Working principle of High Speed Centrifugal Atomizer Spray Dryer


After filtering and heating, the air enters the air distributor at the top of the dryer, and the hot air enters the drying room evenly in a spiral shape. The feed liquid is sprayed (rotating) into very fine mist-like liquid beads through the high-speed centrifugal atomizer at the top of the tower body, and it can be dried into a finished product in a very short time in parallel flow 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.


Pressure spray dryer is characterized by its ability to produce coarse particles and easy maintenance. Because the nozzle hole is small and easily clogged, the feed liquid must be strictly filtered. Nozzle holes are easy to wear and must be made of wear-resistant materials. Pressure nozzles also have a new structure called pressure-airflow nozzles. Its characteristic is that the center is a pressure nozzle, and the surrounding environmental gap is a flow nozzle.
