Abstract
A process and an apparatus for expanding and drying tobacco by means of vapor and/or hot gas are described, in accordance with which the tobacco is metered into an interior space (4) delimited by at least two flat jets (3, 3'). The flat jets flow into the channel from mutually opposing slotted nozzles (2, 2') and are directed towards one another at an acute angle and take up and consequently accelerate the tobacco suddenly. After the velocity acceleration by the flat jets, the tobacco is deflected by means of transverse flow, accelerated again, expanded and dried.
