Working principle and application of Air stream spray dryer
Jan 03, 2019

Air stream spray dryers have exceptionally good properties not found in other drying equipment. The machine sprays air or water vapor through the nozzle at high speed, and separates the liquid into small droplets by friction, so that it completely contacts with the hot air to form heat exchange, and the whole process takes less than half a minute. Especially for the more viscous materials, the effect is more prominent, and the Air stream spray dryer is very convenient to operate.

 

The dried product obtained by the Air stream spray dryer has good uniformity, high product purity and good quality, and the whole production process is also very simple. At present, the equipment is mainly used in the chemical industry: latex, dyes, resins, etc.; the food industry has maltose, dextrin, starch, etc.; the dairy industry, the building materials industry is also often used.

 

The outstanding advantage of the Air stream spray dryer is that the drying speed is fast, and the drying process takes only a few seconds, which is especially suitable for the drying of heat sensitive materials. For liquids with a moisture content of 40-60% (up to 90% of special materials), it can be dried into a powder product at one time. After drying, no pulverization and screening are required, which reduces the production process and improves the purity of the product.
