Centrifuge high speed spray dryer machine/milk powder spray dryer

I. Overview of spray dryer

Spray dryer is the most widely used process in the liquid process molding and drying industry. Suited for generated from solutions, emulsions, suspensions, and plasticity paste liquid raw material in powder, particulate or solid block products. Thus, when the finished product particle size distribution, residual moisture content, bulk density and particle shapes must meet precise criteria. The spray drying is an ideal process.

2.working principle of spray dryer

The air through a filter and the heating, entering the dryer air distributor at the top of the hot air evenly into the drying chamber spirally. The feed solution via the top of the tower body high-speed centrifugal atomizer (rotating) spray into a very fine mist of droplets with hot air cocurrent contact for the finished product may be dried within very short time. Finished continuously from the bottom of the drying tower and cyclone outputs, the emptying of the exhaust gas by the air blower.

3.Performance characteristics.

1.Drying speed is fast, solid-liquid surface area greatly increased after the spraying in the hot air flow, the moment can be evaporated moisture of 95% -98%, and only a few seconds to complete the drying time, especially for heat-sensitive materials drying.

2.The product has good uniformity, mobility and solubility products of high purity, good quality.

3.The production process is simplified, convenient control. For special materials for a moisture content of 40-60% (90%) of the liquid can be dried into a powder or grain products, after drying without crushing and screening, to reduce the production processes, to improve product purity.

4.On product particle size, bulk density, moisture, within a certain range by changing the operating conditions to adjust, control and management is easy.
