In a method and an apparatus for drying plate-shaped products in a multi-level throughflow dryer, moist air stagnated under the housing ceiling is sucked away and delivered into the suction area of axial blowers arranged in the lower levels, where the moist air is then differentially admixed into a quantity of re-heated drying air, and the mixture is delivered to the nozzle boxes of the dryer.

Multistage continuous dryer, especially for plate-shaped products

A bulk material dryer of the through flow type is equipped with an air permeable bulk material conveyor for carrying the bulk material through a dryer housing. The inlet and outlet ends of the dryer housing are sealed by paddle wheels, the paddles of which dip into the layer of bulk material on the bulk material conveyor. A moving filter belt is arranged in the dryer housing in such a position that dust laden air that has passed through the bulk material must also pass through the moving filter belt for the continuous cleaning of the drying air. One or more cleaning devices are arranged along the moving filter belt for in turn cleaning the filter belt, thereby assuring a continuous drying operation.

Apparatus for drying bulk material with a filter for a drying gas

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.
