Abstract
Apparatus wherein tobacco is dried in several successive units each of which contacts a continuous stream of tobacco with hot air. The moisture content of tobacco is measured between a preceding unit and the next-following unit, and the temperature of hot air which is supplied by the next-following unit is respectively increased and reduced when the monitored moisture content of tobacco respectively rises and decreases. The temperature of air which is admitted by the preceding unit is maintained at a constant value. The temperature of air which is supplied by the next-following unit is further influenced, when necessary, in dependency on measurement of such temperature and in dependency on differences between the final moisture content of tobacco and a preselected optimum moisture content. The detector which monitors the moisture content between the preceding and next-following units is built directly into the conveyor which transports the tobacco stream through the drying units.
