How Do Indirect Heat Rotary Dryers Work

Heat transferis accomplished through conduction of theheatfrom the shell to the product and radiation ofheatoff the shell. The internal flighting inside the rotating drum is specially designed to gently roll thematerialbeingprocessed, constantly exposing newmaterialto the heated shell to maximize theheat transfer process.
