Rotary Dryer Input Design

Most of the drying takes place while the material falls through the air blast. using very hot air or combustion gases, rotary dryers can also function as roasters for nuts, sesame seeds, and cocoa beans. a detailed method for the design of rotary dryers, based on a heat exchange approach has been described by nonhebel 1971.
