Ceramic powder spray dryer is widely used in liquid forming and drying industries. It is most suitable for generating powder and granular solid products from solution, lotion, suspension and paste liquid raw materials. Therefore, spray drying is a very ideal process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet accurate standards.

Performance characteristics
The drying speed is fast, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95% -98% of the water can be evaporated instantly, and the drying time is only a few seconds, which is particularly 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 control is convenient. For liquids with a moisture content of 40-60% (up to 90% for special materials), they can be dried into powder products in one go without the need for crushing and screening, reducing production processes and improving product purity. The particle size, bulk density, and moisture content of the product can be adjusted within a certain range by changing the operating conditions, making control and management very convenient.

Working principle
After filtering and heating, the air enters the top air distributor of the dryer, and the hot air enters the drying chamber uniformly in a spiral shape. The feed liquid passes through the high-speed centrifugal atomizer on the top of the tower body, and (rotating) spray into extremely fine mist like liquid beads, which can be dried into finished products in a very short time in parallel with hot air. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged by the fan.

technical specifications

Note: The evaporation rate of water is related to the characteristics of the material and the temperature of the hot air inlet and outlet. When the outlet temperature is 90oC, the water evaporation curve is shown in the above figure (for selection reference). As the product is continuously updated, relevant parameters may change without prior notice.
