Introduction: The spray dryer is a kind of continuous atmospheric dryer that sprays the liquid material into a mist with special equipment to make it dry in contact with hot air. Commonly used to dry some heat-sensitive liquids, suspensions and viscous liquids, such as milk, eggs, tannins and drugs.

Spray dryer features
1. The drying speed is fast, and the surface area of ​​the material liquid after atomization is greatly increased. In hot air current, 95%-98% of water can be evaporated instantaneously, and the drying time is only a few seconds, which is particularly suitable for the drying of heat-sensitive materials.
2, the product has a good uniformity, fluidity and solubility, product purity, good quality. For liquids with a moisture content of 40-60% (up to 90% of special materials), the liquid can be dried into powder products at one time, without crushing and screening after drying, reducing the production process and increasing the product purity.
3, the production process is simplified, the operation and control are convenient. The product particle size, bulk density and moisture content can be adjusted within a certain range by changing the operating conditions, and the control and management are very convenient.
