Chengdu centrifugal spray dryer

Spray drying equipmentThe principle of-----Chengdu Jiachuang Machinery Equipment Co., Ltd,

Among many drying equipment, spray dryer is one of the widely used dryers, which is used to deal with solution, suspension or slurry materials. It can be dried directly from liquid to powder, which is the great advantage of spray dryer; Its disadvantages include low thermal efficiency, large size, low production capacity, and high investment. Spray drying has been widely used in chemical industry, light industry, food industry and other industries, and dye industry in chemical industry due to its special advantage of obtaining powder products with uniform composition directly from solution or suspension system.
The working principle of the spray dryer is to spray the materials into droplets and disperse them in the hot air by spray. The materials and the hot air contact each other in a parallel, countercurrent or mixed flow way, so that the moisture can evaporate rapidly to achieve the drying purpose.
By using this drying method, unit operations such as concentration, filtration, and crushing can be eliminated, and granular products of 30-500 μ m can be obtained. Moreover, the drying time is short, and the general drying time is 5~30s. spray drying is applicable to the drying of highly heat sensitive materials and materials that are easy to disperse in the process of liquid concentration. The product has good fluidity and instant solubility.
