Rotary Dryer Design 101: Retention Time

Retention time, also called residence time, is the amount of time that the material must be processed in the rotary dryer in order to achieve the desired results.. The retention time required for a given application is determined through balancing the necessary process parameters – particle size distribution, air flow velocity, temperature, and more – with the desired outcome; it can then ...

Rotary Dryers - an overview ScienceDirect Topics

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).
