drying medium for drying process in rotary dryer

drying medium for drying process in rotary dryer

Feb 26, 2013 Experiments were conducted in a batch rotary dryer for obtaining the drying kinetics of a non-hygroscopic material with preheated air as the drying medium. The progress of the drying process was investigated for different temperatures and flow rates of the drying medium, initial moisture content of the solids, and rotational speed of the dryer
