ABSTRACT:
Tobacco impregnated with solid carbon dioxide is heated in a chamber to expand the same by sublimation of solid CO.sub.2 and expulsion of CO.sub.2 gas from the tobacco. The expanded tobacco is separated from the internal atmosphere of the expansion device and the tobacco is discharged through an outlet through which gas flows are substantially precluded. The evolved CO.sub.2 gas and other volatile components are removed from the chamber and a portion of the removed gas is heated and returned to the chamber as the expansion medium. The necessity for external steam is avoided as an atmosphere of high thermal diffusivity is maintained in the expansion chamber by precluding the entry of ambient air.
