LPG high-speed centrifugal spray dryer

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

Brief description: spray drying is a widely used process in liquid process forming and drying industry

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

Principle:
The air is filtered and heated before entering 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 at the top of the tower body, and (rotating) spray into extremely fine droplets, which flow in parallel with hot air and can be dried into finished products in a very short time. 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.

Features:
● The drying speed is fast, and after atomization, the surface area of the material liquid greatly increases. In the hot air flow, 95% -98% of the water can be evaporated instantly, and the drying time is only a few seconds. It is especially suitable for drying thermosensitive 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. After drying, there is no need for crushing and screening, reducing production processes and improving product purity. The particle size, bulk density, and moisture of the product can be adjusted within a certain range by changing the operating conditions, making control and management very convenient.
