Dryer has a longer prismatic body on legs. On both its largest opposite sides it has long openings into which enters the conveyor run of an endless belt, to immediately above the space, where there are long parallel blowing nozzles, opening downwards. Over the nozzles are two separate spaces; in the upper is a blower, belt-driven from outside; this space, the nozzles, and the space below them end at the front part of the dryer's front wall, which has a flap valve to form a chamber. The chamber is connected only with the nozzles blowing on the conveyor and the fan space. In the interspace between this space, whic has a face outlet, and the chamber is a forced air circulation from a heat source. |
