High Speed Centrifugal Spray Dryer
Starch Granule Pigment Food Chemical Stainless Steel Centrifugal Spray Dryer
Introduction
Brief introduction: In this machine, the fully-closed structure is adopted, all parts are made of stainless steel, and there is
the 3-stage purifying device. After the filtering, the air meets the 100000-grade standard. There are cooling devices for the
reactor, the temperature of the container wall is less than 80℃, and even the raw products are stayed on the wall, will not be burned. The powder rate is as high as more than 95%, and there is no powders mixing or wall hanging.
Working principle:In this machine, the centrifugal spraying and drying technology is adopted. With the high-speed centrifugal atomizer, after the spraying, powders are atomized, can be contacted with hot air completely, and the drying is completed instantly.
The spray dryer is one of the continuous atmospheric dryers. The liquid material is sprayed with a special device to form a mist and is dried in contact with hot air. For the drying of some heat-sensitive liquids, suspensions, and viscous liquids, such as milk, eggs, tannins, and drugs. Also used for drying fuels, intermediates, soap powder, and inorganic salts.

Working Principle
The air is filtered and heated into the top of the dryer air distributor, hot air into the spiral evenly into the drying chamber. The material liquid is sprayed into a finely 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.
