Abstract

The invention relates to a method and device for regulating the output moisture content of tobacco conditioned by a loosening/conditioning and optionally casing (saucing) drum comprising injecting a throughflow of water into the infeed region of the drum by a first nozzle regulated depending on the target value for the tobacco output moisture content and the actual values for the tobacco mass flow, the steam throughflow and the tobacco input moisture content; and injecting a throughflow of water in the outlet region of the drum through a second nozzle, the target value of which is computed depending on the target value and actual value for the tobacco output moisture content.
