    • Spray drying is the most widely used industrial process for particle formation. The spray dryer consists of an atomizer, air heater, drying chamber, systems for powder recovery such as a cyclone. It is possible to produce continuously dry particles from liquid feedstocks (Fig. 1). Firstly, droplets of a liquid feedstock are generated by the atomization from the spray nozzle. After that, the droplets are put in contact with hot air in a drying chamber. Evaporation of solvents (e.g., water, ethanol) from the droplets proceeds under controlled temperature and airflow conditions to form dry spherical particles. Then, the particles are continuously discharged from the drying chamber and collected using a cyclone or a filter. The whole process generally takes no more than a few seconds.
