dryer to the other. In direct heat rotary dryers, a hot gas flowing through the dryer provides the heat required for vaporization of the water. To promote gas-solid contact, most direct heat dryers have flights (see Figure 1), placed parallel along the length of the shell, which lift solids and make them rain across the dryer section. The
