Centrifugal spray dryers primarily utilize the high-speed rotation of a rotary atomizer to eject droplets, which are then dried with hot air into powder or granules. This spray dryer is both centrifugal and airflow. When experiments require powder, the airflow type is preferred, as it has a long service life and is less prone to damage. This is also a drawback of centrifugal atomizers. When experiments require uniform powders or granules, choose a centrifugal atomization system for spray drying.
