<p>An apparatus and method for moistening tobacco in which the non-condensibles in a mass of dry, compressed tobacco are substantially entirely eliminated by subjection to a very low absolute pressure, preferably below 1 in. Hg, followed by a first steaming to a pre-determined temperature under the influence of a maximum pressure differential, holding, re-evacuation, during which a loosening occurs, and a final steaming.</p> |
