Principles of Rotary Drying. The directly heated rotary dryer operates on the principle of lifting and showering the product through a hot gas stream moving either in parallel or counter-flow whereas with the indirect dryer, which is more suited to fine and dusty materials, there is little or no contact between the product and the drying gases since they are heated from the outside, via a ...

Nov 26, 2001· In direct heat rotary dryers, a hot gas flowing through the dryer provides the heat required for the vaporization of the water. To promote gas–solid contact, most direct heat dryers have flights, placed parallel along the length of the shell, which lift solids and make them rain across the section of the dryer Fig. 1 ).
