Process of rotary drying

Drying process can be defined as the vaporization and removal of water or other liquids from a solution, suspension, or other solid-liquid mixture to form a dry solid. It is a process that involves heat and mass transfer. Drying occurs as a result of the vaporization of liquid by supplying heat to wet feedstock, granules, and so on

    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)
