product description
Spray drying is a widely used process in the formation of liquid process and drying industry. It is suitable for generating powder, granular solid products from solution, lotion, suspension and paste liquid raw materials. Therefore, when the particle size distribution, residual moisture content, accumulation density, and particle shape of the finished product must meet the standard, dry spray drying is a better process.
working principle
The air is filtered and heated, entering the air distributor on the top of the dryer, and the thermal air is spiral and uniformly enter the dry room. The liquid is a high -speed centrifugal atomizer at the top of the tower body, and (rotating) spray into extremely subtle fog -shaped liquid beads, which can be dried in a very short time with hot air. The finished product is continuously output by the bottom of the dry tower and a whirlwind separator, and the exhaust gas is emptied by the fan.
Performance characteristics
◎ The drying speed is fast. The surface area after the liquid is increased greatly. In the hot air, it can evaporate 95 % -98 % of water in an instant. It only takes a few seconds to complete the drying time, which is particularly suitable for the drying of thermal material.
◎ The product has good uniformity, liquidity, and solubility, high product purity, and good quality.
◎ The production process is simplified and the operation control is convenient. For liquids with a wet content of 40-60 % (special materials can reach 90 %), liquids can be dried into powder-granulated products at one time. After drying, they do not need to be crushed and screened to reduce production processes and improve product purity. The product particle size, loosening density, and water can be adjusted by changing the operating conditions within a certain range, and the control and management can be convenient.
