Abstract A mathematical model for the rotary dryer that determines the total residence time is developed. Experiments were performed in a laboratory-scale direct contact rotary dryer with the gas flowing concurrently with the solids. The model predictions depicted that the total residence time decreases with increasing the inclination of the rotary drum, the speed of rotation and
