Spray Dryer Has Good Performance

The spray dryer is a kind of continuous and ordinary pressure dryers. It nebulizes the  liquid with special equipment to make it contact with the hot air to be dried. It is commonly used to dry some heat-sensitive liquid, suspension and viscous liquids, such as milk, eggs, tannin and drugs. In addition, it is also used for the drying of fuel, intermediates, soap powder, and inorganic salts, etc.

Features: 

1. The speed of drying is fast; after the nebulization, the surface area of the liquid will be  greatly increased and in the hot air flow, 95% -98% of the moisture can be evaporated. The drying time only requires ten seconds it is especially suitable for the drying of heat sensitive materials.

2. It has a wide application range, according to the characteristics of the material, it can be dried with hot air or the cold granulation; the adaptability to the materials is strong;

3. The operation is simple and stable, it is easy to control and to realize the automatic operation.

The product dried by the spray dryer has good uniformity, mobility and solubility and the products have high purity and good quality. The production process is simplified to make it convenient to control the equipment. As for the liquid whose moisture content is 40-60% (the moisture content of some special materials can be up to 90%), it can be dried into the powdery or granular products. Moreover, after the drying, there is no need to conduct the crushing and screening, reducing the production processes, which is helpful to improve the product purity. The product particle size, bulk density, moisture can be adjusted within a certain range by changing the operating conditions.
