Production type high-speed centrifugal spray dryer

Production type high-speed centrifugal spray dryerIntroduction to Principles

Spray drying is widely used in liquid forming and drying industries. It is suitable for generating powdery and granular products from solutions, lotion, suspensions and pumpable paste liquid raw materials. Generally, different tower diameters, heights, and supporting accessories are used based on the material status and requirements. Due to its high energy consumption, it is usually suitable for products with high added value or other processes that cannot be achieved.

Features of production centrifugal spray dryer:
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, and the drying time is only a few seconds. It is particularly suitable for drying heat sensitive materials.
The product has good uniformity, fluidity, and solubility, high purity, and good quality.
Simplified production process and convenient operation control. 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.Production type high-speed centrifugal spray dryer
Principle of production centrifugal spray dryer:
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 the spray becomes a very fine atomized liquid bead, which can be dried into finished products in a very short time in parallel with the 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.
