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 a dual-purpose centrifugal and airflow type. Airflow is preferred when powder is required, as it offers a long service life and is less prone to damage. This is also a drawback of centrifugal atomizers, so choose a centrifugal atomization system when a uniform powder or granules is desired.
