High speed centrifugal spray dryer with good quality and fast drying speed
Jan 30, 2019

High-speed centrifugal spray dryers are one type of continuous dryers. Due to their fast drying speed, spray dryers are best suited for the production of granular, powdery or lumpy solid products from emulsions, solutions, plastic paste liquids and suspensions.

The surface area of the high-speed centrifugal spray dryer is greatly increased after atomization. In the hot air flow, 95%-98% of the water can be evaporated instantaneously. The drying time is only a few seconds, which is especially suitable for the drying of heat sensitive materials. The product has good uniformity, fluidity and solubility, and the product has high purity and good quality. The production process is simplified and the operation control is convenient. For liquids with a moisture content of 40-60% (up to 90% of special materials), the products can be dried into powdered products at once, without pulverization and screening after drying, reducing production processes and improving product purity.

The air of the high-speed centrifugal spray dryer is filtered and heated to enter the air distributor at the top of the dryer, and the hot air enters the drying chamber in a spiral shape uniformly. The liquid is sprayed into a very fine misty liquid droplet through a high-speed centrifugal atomizer at the top of the tower body, and it can be dried into a finished product in a short time by cocurrent contact with hot air. The finished product is continuously discharged from the bottom of the drying tower and the cyclone, and the exhaust gas is evacuated by the induced draft fan.
