What is a spray dryer

- May 18, 2017-

The spray dryer is converted into hot air by heating and enters the hot-air distributor at the top of the drying chamber, and then enters the drying chamber evenly. And the appearance of spiral rotation, at the same time the material liquid to the device at the top of the drying chamber centrifugal atomizer, so that the liquid atomization into tiny droplets of spray, liquid and hot air flow contact, water quickly evaporation, in a very short time drying for finished products. The finished product is discharged from the bottom of the drying tower and the cyclone separator, and the exhaust gas is drained by the blower.

In the drying top of the hot air, while the feeding liquid to the top of the tower, through atomizer spray droplets, these droplets of liquid surface area is very large, with high temperature hot air after contact with the rapid evaporation of moisture in a very short time will become dry products from the bottom of the drying tower exhaust gas and liquid droplet contact temperature significantly decreased, the humidity increases, it is used as exhaust gases extracted by exhaust air, the particles entrained in the waste separation device recycling.
