Abstract
Shreds of tobacco are conveyed across a rising stream of saturated steam and in a shower of hot water droplets so that the temperature and moisture content of shreds increase to a value at which the shreds are pliable. The shreds are thereupon introduced into a drying unit wherein they rise and fall while moving across a rising stream containing a mixture of superheated water vapors and hot air to be alternately subjected to more and less pronounced drying action which causes pronounced crimping of the shreds. The dried shreds are immediately cooled to room temperature prior to admission into the magazine of a cigarette maker.
