Today, mostrotary dryingsystems use some form of EGR. Arotary dryingsystem requires a specific ratio of mass-of-gas to mass-of-material for stable pneumatic conveying. Historically this was always done with excess air flow. Thedryingand combustion gasses typically represent about one-third of the gasses going through thedryer.

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

Most of thedryingtakes place while the material falls through the air blast. Using very hot air or combustion gases,rotary dryerscan also function as roasters for nuts, sesame seeds, and cocoa beans. A detailed method for the design ofrotary dryers, based on a heat exchange approach has been described by Nonhebel (1971).
