    Product introduction

    Spray drying is the most widely used technology in liquid forming and drying industry. It is most suitable for producing powdery and granular solid products from solution, emulsion, suspension 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.

    Working principle

    The air is filtered and heated, and enters the air distributor at the top of the dryer. The hot air spirals evenly into the drying chamber. 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 discharged from the bottom of the drying tower and the cyclone separator, and the exhaust gas is drained away by the fan.

    Performance characteristics

    The drying speed is fast, and the surface area of the slurry is greatly increased after atomization. In the hot air flow, the water content of 95%-98% can be evaporated instantaneously. The drying time is only a few seconds, especially for the drying of heat sensitive materials.

    The product has good uniformity, fluidity and solubility. The product has high purity and good quality.

    The production process is simplified and the operation control is convenient. For liquid containing 40-60% (90% of special materials), the liquid can be dried into powder at a time. After drying, it does not need to be crushed and screened, so as to reduce production process and improve product purity. The size, density and moisture of the product can be adjusted within a certain range by changing the operating conditions. The control and management are very convenient.
