ABSTRACT:
A continuous stream of tobacco particles is conveyed through a conditioning zone wherein the stream is agitated and is directly contacted by a current of hot air. The moisture content of the thus dried tobacco particles is measured downstream of the conditioning zone and the temperature of hot air is changed when the measured moisture content of dried tobacco particles deviates from a desired value. A second parameter of hot air (e.g., its initial moisture content) is varied when the temperature of freshly dried tobacco particles deviates from a preselected temperature. This ensures that the moisture content of tobacco particles does not fluctuate subsequent to cooling which follows the drying operation.
