· Direct vs Indirect Fired Heaters for Spray Dryers Posted on 14th January 2019 in Dryers by John Real The question of direct or indirect fired spray dryers is one that is starting to be asked in the United States more and more often, especially in food production appliions.
Rotary Dryers A Rotary Dryer uses a rotating cylindrical drum, which acts as a container for the uniform transfer of thermal energy from a hot gas stream to a moisture laden product, for the purpose of moisture reduction in the product. Wet product is introduced into the inlet of the drum where it is dried as it is conveyed to the drum's outlet.

Direct and indirectfired rotary dryers are used in a variety of industrial settings to dry bulk solids. While the two are both comprised of a rotating drum and function to reduce a material's moisture, several differences between direct and indirect dryers exist:
· Generally speaking, directfired rotary drum dryers are more efficient that indirectfired dryers. However, there are advantages to choosing an indirectly heated rotary dryer. The customers can select to use DirectFired Rotary Dryer s or IndirectFired Rotary Dryers according to the features of raw material and the end use of the dry product.
HiTemp Indirect Fired Rotary Kiln System Overview. The Processor Tube System is designed using three separate components. Due to the carbon process materials, a onequarter inch, hightemperature, 304 stainless steel alloy cylinder is used for the contact surface.
Although indirectfired rotary kilns and dryers closely parallel the directfired rotary devices in operation, t he indirectly fired kiln or dryer is distinct from its directfired counterpart, due to the fact that all heat transferred to the processed material is conducted (and/or radiated) through the vessel shell wall.

In the case of a rotary dryer, the material is being heated directly by the gases, ie. convection. However, the material is also getting heat from the shell of the rotary dryer through means of conduction. In an indirect fired rotary kiln, conduction is the only source of heat transfer.
