Abstract

The tobacco is impregnated with the liq. impregnant for a time sufficient for the tobacco to take up 1-40% of the agent, ie. mins - 4 hrs. The tobacco is then subjected to expansions so as to induce bursting of the particles, pref. by heating with a hot gas at 232 - 343 degrees C for 0.6 - 3 secs. A vol. mass of 0.38 - 1.05 g/cm3 can easily be obtd.
