LPG-100 High speed centrifugal spraying dryer

LPG-100  High speed centrifugal spraying dryer 

Product Introduction

Spray drying is widely used in liquid forming and drying industries. It is especially suitable for generating powdery 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 must meet the standard of ^, spray drying is a very ideal process.

working 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 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.

Performance characteristics

The drying speed is fast, and the surface area of the material liquid greatly increases 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. It is especially suitable for drying thermosensitive materials.

The product has good uniformity, fluidity, and solubility, high purity, and good quality.

The production process is simplified and the operation and control are 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. After drying, there is no 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.
