Spray drying is the most widely used technology in liquid forming and drying industry. It is most suitable for producing powder and granular solid products from solution, emulsion, floating liquid and paste liquid raw materials. Therefore, when the particle size distribution, residual water content, bulk density and particle shape of finished products must conform to the exact standard, spray drying is a very ideal process.

spray dryer working principle
The air is filtered and heated and enters the air distributor at the top of the dryer. The hot air enters the drying chamber spirally and evenly. The high speed centrifugal atomizer at the top of the tower (swivel) is atomized into tiny droplets of mist, contacting with the hot air and flowing into the finished product in a very short time. The finished product is continuously exported from the bottom of the drying tower and the cyclone separator, and the exhaust gas is exhausted by the fan.
spray dryer performance characteristics
1.The drying speed is fast, the surface area of the material increases greatly after atomization, and 95% - 98% of the moisture can be evaporated instantly in the hot air flow. The drying time is only a few seconds, especially for the drying of heat sensitive materials.
2.The product has good uniformity, fluidity and solubility, high purity and good quality.
3.The production process is simplified and the operation and control are convenient. For the special material with 40 moisture content, the liquid can be dried into powder at one time to reduce the production process and improve the purity of the product. It is easy to control and manage the granularity and moisture of the product within a certain range by changing the operation.
