Liquid material feeding: The liquid material is first fed into the feeding system of the high-speed centrifugal spray dryer. These materials may be solutions, suspensions or emulsions.
Spray: The feeding system sprays liquid materials into small droplets. This is usually achieved through the use of high-pressure nozzles or rotary atomizers. The purpose of spraying is to increase the surface area of the liquid for better contact with the hot air flow.
Drying: The spray droplets enter the drying chamber and come into contact with the hot air flow. The hot air flow is usually generated by a burner heating the air and then spraying it through a nozzle or spinner in the drying chamber. When the hot air flow comes into contact with the droplets, the water in the droplets will evaporate rapidly, causing the droplets to gradually turn into solid particles.
Separation: During the drying process, the solid particles gradually move toward the bottom of the drying chamber through centrifugal force and air flow. At the bottom, the solid particles are separated from the air flow by centrifugal force.
Collection: The separated solid particles are collected to become the final dry product. This is usually done with a collector or filter.
The high-speed centrifugal spray dryer uses high-speed spray and hot air flow to quickly convert liquid materials into solid particles. This drying method has the characteristics of efficient, fast and continuous production, and is widely used in food, pharmaceutical, chemical and other industries.
