method for continuous conditioning, particularly thermal condition of bulk goods, preferably vegetable bulk material, such as cereals, herbs, tobacco or the like

摘要

For continuous conditioning, particularly thermal conditioning, such as cooling, warming, drying, moistening and the like, of particulate material, preferably vegetable particulate material such as cereals, herbs, tobacco and the like, the particulate material is continuously conveyed mechanically along a conveyor belt leading through a closed, tunnel-like conditioning station and is exposed, in the conditioning station, to the influence of a substantially gaseous heat exchange medium guided to the conditioning station through at least one aperture. The heat exchange medium is tightly bundled on passing through the aperture (6, 6', 6'') and is then guided as a free jet (8) through the particulate material, forcing the particulate material aside, in such a way that deflection of the jet (8) in all directions is effected at a wall (2) of the conditioning station lying opposite the aperture. The deflected parts (10) of the jet are sucked, by the pumping action of the free jet, downwards and back into the range of action of the free jet, and the particulate material is compressed, in a movement aligned at right angles to the free jet, between the vacuum region (9) of the upward-directed free jet and the excess pressure region of the downward-directed parts of the jet.
