Product descriptions
Working Principle
After the air is heated into clean hot air through the air inlet filter and heater, it enters into the air distributor at the top of the drying tower body, and the hot air enters into the drying tower body uniformly in spiral shape. The material is fed into the centrifugal sprayer or pressure nozzle at the top of the drying tower by the supply pump, and rotates or sprays into very fine mist droplets, which come into contact with the hot air in the downstream flow, and the water evaporates rapidly, and dries into the finished product in a very short period of time. The finished products are discharged from the bottom of the drying tower and the cyclone separator, and the exhaust gas is purified by the dust removal system and then emptied. When the dried products are easy to oxidize or have toxicity, the inactive gas medium formed by circulating nitrogen can be used to replace the commonly used air medium, in addition to the recovery of products, organic solvents can also be recovered.
Features
1.Fast drying speed. The completion of the drying time generally takes only about 5~40s.
2.The product has good uniformity, fluidity and solubility. As the relative size of the droplets after atomization is relatively uniform, the droplets are dried at the instant of contact with the hot air, the droplets are basically spherical hollow powder after drying and shaping, easy to flow and dissolve, and the granularity of the material is relatively uniform. The production process is simplified, can be continuous mass production. Direct use of liquid raw materials made of a few to several hundred microns of powder products, evaporation, crushing, granulation and other processes can be eliminated.
3.Easy to control product quality index. Adjust the residual moisture, particle size and bulk density of the product by changing the conditions of solid content, atomization and drying temperature of the liquid raw material.
4.Easy to control product quality index. Adjust the residual moisture, particle size and bulk density of the product by changing the conditions of solid content, atomization and drying temperature of the liquid raw material.
5.High degree of automation, easy to operate, stable and reliable. Equipment structure is simple, no complex components, easy to maintain and repair; with temperature, pressure, oxygen content and other online monitoring and self-diagnostic control functions, to ensure the safety and stability of the drying process, can dynamically and efficiently adjust the transient state to ensure the quality of the product.
