Dryers
Abstract
For the purposes of layout design, solids dryers may be considered in two classes.

The second type of dryer has a medium to high flow of heated air or inert gas as the drying medium. Their air-heating systems, exhaust-gas cleaning, and handling systems are often as large as the dryer itself.
