1. Description:
The spray drying is the technology which is widely used in the liquid technology shaping and in the drying industry. The drying technology is most suitable for producing the powder or particle solid products from the materials, such as: Solution, emulsion. So when the particle size and distribution of the final products, their residual water contents, the stacking density and the particle shape must meet the precision standard, the spray drying is one of the most perfect technologies.

2. Principle:
After the filtering and heating, the air enters into the air distributor from the top of the drier. The hot air enters into the drying room in the spiral form and uniformly. By passing through the high-speed centrifugal spray on the top of the tower, the material liquid will rotate and be sprayed into the extremely fine mist liquid beads. Through the very short time of contacting the heat air, the materials can be dried into the final products. The final products will be discharged continuously from the bottom of the drying tower and from the whirling separator. Finally the waste gas will be discharged from blower.

Basic flow chart:
Centrifugal atomizer is as follows:
