Drying medium for drying process in rotary dryer

Dec 22, 2010 Abstract: Experimental and theoretical investigations on drying of non-hygroscopic material were conducted in a rotary dryer with preheated air as the drying medium. The progress of the drying process was experimentally investigated batch wise and under continuous conditions for different temperatures and flow rates of the drying medium, rotational speed and inclination of the cylinder
