Abstract
A material dryer, especially for bulk material, includes a single entrance pressurized drum housing and an endless conveyor for passing the material through the drum housing. The conveyor may include a screen belt. The housing and the dryer components in the housing are divided into identical modular units, except for the entrance and discharge units. Each modular unit includes a tubular housing section, a conveyor section, and a treatment medium handling section for circulating and heating the drying medium such as super-heated steam. The heating and circulating of the treatment medium is individually controllable in each modular unit. The entrance unit is equipped with conveyor belt guides and with a sealed material supply device. The discharge unit is equipped with a belt drive and with a sealed material discharge device.
