Spray drying is the most widely applied technology in liquid forming and drying industry.It is most suitable for producing powdery, granular or bulk solid products from solution, emulsion, suspension and plastic paste liquid.Therefore, spray drying is an ideal process when the particle size distribution, residual water content, accumulation density and particle shape must conform to the precise standard.

After filtering and heating, the air enters the top distributor of the spray drying machine, and the hot air goes into the drying chamber evenly and evenly.The high speed centrifugal atomizer of the top of the material of the tower is made into very fine mist droplets, which can be dried in a very short time with the hot air.The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the exhaust gas is drained away from the draught fan.

Spray dryer is highly automated and flexible, which controls the size of finished products.The spray dryer is used to spray the compressed air or water vapor over the nozzle at a speed of more than 300m/s, and the friction force produced by the velocity difference between the gas and liquid is produced, and the liquid is separated into tiny droplets.The full contact between droplet and hot air and heat exchange can complete the whole drying process in 10-30 seconds.The drying time of the air spray dryer is very short, only 10~30 seconds. Because of the short drying time, the product can keep the uniform fine particles (the product has good dispersibility, fluidity and solubility).It is flexible. For the product's grain, loose density, water, product nature (no dust, fluidity, wettability, quick solubility), in a certain range, the operation conditions can be changed to adjust, control and management are convenient.For viscous paste material, paste material has excellent effect.The finished product is of good quality. It can retain the material's color, aroma, taste, and other biological activity; the moisture content of the final product; the nozzle structure is simple (the cost of the atomization system is only pressure type 1/3, centrifugal 1/5), the possibility of blocking is small, the one-time input cost is low, and the later use cost is also very low.
