IMPROVED TOBACCO EXPANSION PROCESS

摘要

An improved tobacco treating expansion process involving controlling the moisture content of tobacco and the pre-separator residence time thereof in a treatment of the moisture controlled tobacco under preselected pressures and temperatures so that the tobacco at exit from the drying step of the process has a moisture content in the range of approximately 9% to approximately 15% oven volatiles by weight and fill values at least equivalent to fill values of tobaccos dried to a lower moisture content not exceeding 6% oven volatiles.
