Spray dryers: Applications, performance, essential parts and classifications

Spry dryers are one of the most functional types of dryers in chemical, pharmaceutical and food industries. In recent years, various studies have been conducted on the development of essential parts used in spray dryers in order to improve quality of the processed products. Of among unique properties of spray dryers, automatic continuous operation, rapid drying and manufactured products with desired size and density can be referred. The aim of this study was to investigate the dryers’ applications and performance, various essential parts including heating systems, atomizer, drying tower and recovery system as well as to classify the dryers based on the flow type, the stage number(s) and the cycle types.
