Abstract: Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. Ultrasonic nozzles has emerged as a promising technology that offers several advantages over conventional spray drying methods. The use of ultrasonic vibrations for spray formation can effectively address the challenges associated with conventional atomizers, including the requirement for high temperatures and high-pressure fluids. Compared to conventional spray drying, ultrasonic atomizers can deliver a spray with lower velocity, operate at lower temperatures, produce smaller particle sizes, achieve high evaporation rates, and impose low mechanical stress.
