Multilevel belt dryer for food products - with ends of two upper belt conveyors which overlap and is esp. for hops or tea

摘要

Food products are deposited onto a belt conveyor inside a large drying chamber to travel half the length of the chamber then fall onto another conveyor immediately below, the ends of these two conveyors overlapping before, falling onto further conveyors housed lower down the chamber. Air is fed through ducts under the belts of all the conveyors including the region of overlap of the upper conveyors. Baffle plates around this overlap region include a sealing plate between the belts where they pass around the return rollers.
