Abstract
A method of conditioning tobacco including the steps of: a) vibrating tobacco particles by means of a vibratory conveyor to produce a continuous stream to be transferred along a predetermined path, the conveyor being vibrated in such a manner that the stream of tobacco particles remains in contact with the supporting surface of the conveyor during transportation; b) contacting substantially all of the particles of tobacco with steam by continuously passing steam upwardly through perforations in said conveyor; and c) maintaining said steam at a pressure sufficient to enable the steam to diffuse into the interstices between the particles without causing said stream of tobacco particles to be lifted out of contact with the supporting surface of the conveyor, wherein the steam passing by way of the perforations includes a component of flow parallel with the supporting surface of the conveyor.
