रोटरी ड्रायर

The rotary dryer also known as tumbling dryer is an equipment employed to minimize the moisture content of feed materials by bringing it in direct contact with a heated gas. It consists of an inclined long drum or cylindrical shell often fitted with internal flights or lifters; rotated slowly upon bearings through which the material to be dried flows with a tumbling/cascading action in concurrent (for heat-sensitive materials) or counter-current flow with the heating air or gases.
