How to prevent the spray dryer from sticking to the wall?
The spray dryer sprays the material into droplets and disperses it in hot air. The materials are in contact with the hot air in a cocurrent, countercurrent or mixed flow manner, so that the water evaporates quickly to achieve the purpose of drying. By means of spray drying, unit operations such as concentration, filtration, and pulverization can be omitted, and drying time is short, product fluidity and fast solubility are good, and thus it is widely used in medicine and other industries.
