(1) The drying speed is very fast. After the liquid is sprayed, the surface area is large. In a high temperature air stream, it can evaporate in an instant. (2) The temperature of the droplets during the drying process is not high and the product quality is good. Spray drying uses a wide temperature range (80-800 degrees). Even with high temperature hot air, the exhaust air temperature is not very high. In the early stage of drying, the material temperature does not exceed the wet bulb humidity of the surrounding hot air. it is good. For example, defects such as protein changes, vitamin loss, and oxidation are less likely to occur. The quality of heat sensitive materials, organisms and drugs is basically close to the standard for drying under vacuum. (3) The product has good dispersibility, fluidity and solubility. Since the drying process is completed in the air, the product can basically maintain a spherical shape similar to the droplets, and has good dispersibility, fluidity and solubility. (4) Decomposition of production process, convenient operation and control Spray drying is usually used to treat solutions with a moisture content of 40%-60%. Even if the moisture content of special materials is as high as 90%, it can be dried into a powdery product at the same time without concentration. Most products do not need to be pulverized and screened after drying, which reduces the production process and simplifies the production process. The particle size, bulk density and moisture of the product can be adjusted within a certain range by changing the operating conditions, and the control and management are very convenient. (5) Preventing pollution and improving the production environment Since spray drying is carried out in a closed drying tower, this avoids the drying of dry products in the workshop. For toxic and odorous materials, the production process of closed circulation system can be used to burn toxic gas and odor, prevent air pollution and improve the production environment. (6) It is suitable for continuous large-scale production. Spray drying can meet the requirements of large-scale production in industry. The dry product can be continuously discharged, and combined with cooler and wind power for post-processing, it can form a continuous production line.
