    Jan 11, 2016· A rotary dryer is said to be of the direct type if, by virtue of its design, heat isadded to or removed from the solids by direct exchange between the gas and solids. The direct heat dryers are the simplest and the most economical class. They are used when direct contact with the hot gas or air is not detrimental to the fed.

    The heating medium of the indirect-heat rotary drum dryer is not contacted with the material directly. All the heat required is transferred to thematerial through the heat transfer wall. While thematerial directly contacts with the internal heating medium, andmainly dried by convective heat transfer. Thus, the latter is used more widely.

    Rotary dryerswork by tumbling material in a rotating drum in the presence of a drying air. They can also be indirectly heated to avoid direct contact between the material and processing medium. The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum.
