Abstract
Apparatus for drying tobacco which is caused to pass through a steam-heated rotating drum has a blower for admission of hot air into a first conduit which discharges hot air into the inlet of the drum or into a second conduit which discharges hot air into the outlet of the drum. The temperature of hot air which flows into the inlet is regulated in dependency on changes in moisture content of tobacco ahead of the drum, and the temperature of hot air which flows into the outlet is regulated in dependency on changes in moisture content of dried tobacco. A first pipe draws vapors-containing air from the outlet when the drum receives hot air via first conduit, and a second pipe draws vapors-containing air from the inlet when the drum receives hot air from the second conduit.
