The Option of Thermal Drying | WWD

 · Indirect. In indirect thermal drying, the heating process is separate from the drying process. In this conductive heat-transfer process, the solids are dried by contact with the heated metal. Both methods are designed to capture most of the exhaust from the dryer chamber and recycle it to feed the furnace or reheat it for continued drying.

Drying - Wikipedia

Air heating increases the drying force for heat transfer and accelerates drying. It also reduces air relative humidity, further increasing the driving force for drying. In the falling rate period, as moisture content falls, the solids heat up and the higher temperatures speed up diffusion of water from the interior of the solid to the surface.
