Indirect Heating Rotary Dryer
Rotary dryers use either direct convection heat transfer or indirect heat transfer, which depends upon hot surfaces within the dryer to provide heat by conduction and radiation. The determination of direct versus indirect heat is contingent upon the properties of the material to be dried, the process conditions and the desired end product.

Direct and Indirect Rotary Dryers: What's the Difference?
Operation: direct-fired dryers use direct contact between the material and drying air to dry the material, with the potential of using internal lifting flights to maximize the heat transfer. Conversely, indirect dryers use heat emanating from the drum's shell to dry material via radiation and conduction, avoiding direct contact between the ...

How Steam Tube Dryers Process Materials
A steam tube dryer is like a rotating shell-and-tube heat exchanger in which medium pressure, saturated steam is charged through a rotary steam joint, into the manifold and then into several heat transfer tubes – typically at a nominal 100-150 psig (and up to 450 psig/500F service for reacting granular solids).
Indirectly heated tube drum dryers
In doing so, the water contained in a product is evaporated into the dryer air, which is preheated by heat exchangers. At the end of the dryer drum, the dried product is separated in a drop box and discharged through an air-tight rotary valve. Warm and moist dryer air is extracted and dedusted in cyclones or bag filters.
