Product introduction
  Spray drying is a process used in liquid forming and drying industry. It is suitable for producing powdery and granular solid products from solution, emulsion, suspension and paste liquid raw materials. Therefore, spray drying is an ideal process when the particle size distribution, residual water content, bulk density and particle shape of finished products must meet precise standards.
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.
Performance characteristics
◎The drying speed is fast, and the surface area of material and liquid is greatly increased after atomization. In hot air flow, 95% - 98% of water can be evaporated instantaneously. The drying time is only a few seconds. It is especially suitable for drying heat sensitive materials.
◎The product has good uniformity, fluidity and solubility, high purity and good quality.
◎The production process is simplified and the operation and control are convenient. For the liquid containing 40-60% moisture (90% of special materials), it can be dried into powder products at one time without crushing and screening after drying, which can reduce the production process and improve the product purity. The particle size, bulk density and moisture of the product can be adjusted by changing the operating conditions in a certain range, so the control and management are very convenient.

Note: Water evaporation is related to material characteristics, hot air intake and outlet temperature. When the outlet temperature is 90 < sup > O C, the water evaporation curve is shown in the figure above (for reference). With the product updating, the relevant parameters are changed without prior notice.
