ABSTRACT:
A tobacco feeder assembly utilizes a column of tobacco and a rotary conveyor to feed tobacco particles to a treatment zone which is maintained at above atmospheric pressure. The column of tobacco is maintained in the feed tube by control of the rotational speed of the rotary conveyor and provides an effective vapor barrier which prevents egress of the impregnating or treatment medium into the atmosphere.
