[0002] Spray drying towers are equipment used for drying biopesticides, medicines, and food microorganisms. Spray drying is a drying process in which a raw liquid is placed in an atomizer and separated into droplets. The powdery product is obtained by direct contact between hot air or other gases and the droplets. The spray drying tower needs to heat the air to between 120℃ and 250℃. This temperature range is set according to the drying requirements of different materials. Most materials require higher temperatures during the drying process. Therefore, energy-saving spray drying towers that reuse waste heat are needed.
