Product introduction：
Spray drying is widely used in liquid process forming and drying industry. It is suitable for producing powder and granular solid products from solution, emulsion, suspension and paste liquid raw materials. Therefore, when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product should meet the requirements, spray drying is a good process.

Note: Moisture evaporation is related to material characteristics, solid content and hot air inlet and outlet temperature. The user can select the heating method according to the local energy situation, and select the dust collection and dust removal method according to the material characteristics. | |||||||||||||
Working principle：
The working process of the unit is the feed liquid through the diaphragm pump high pressure input, spray mist droplets, and then flow down with hot air, most of the powder particles are collected by the bottom of the tower discharge port, exhaust gas and its tiny powder is separated by the cyclone separator, exhaust gas is discharged by the extraction fan, powder is collected by the pollinator cylinder located at the lower end of the cyclone separator, the fan outlet can also be equipped with a secondary dust removal device.
Product characteristics：
● The drying speed is fast, the surface area of the material liquid is greatly increased after atomization, and 95%-98% of the water can be evaporated instantly in the hot air flow, and the drying time is only a few seconds, which is suitable for the drying of heat-sensitive materials.
● The product has good uniformity, fluidity and solubility, high product purity and good quality.
● The production process is simplified and the operation control is convenient. For the moisture content of 40-60% (specific materials can reach 90%) of the liquid can be dried into powder products, dry without grinding and screening, reduce the production process, improve product purity. The product particle size, loose density, moisture, in a specific range can be adjusted by changing the operating conditions, control and management are very convenient.
