Abstract
A process is disclosed for increasing the filling power of tobacco lamina filler without the use of exogenous impregnants by contacting the filler with a heat transfer medium such that heat is transferred rapidly and substantially uniformly from the medium to the filler for a total contact time sufficient to stiffen and expand the filler. The filler has an OV value, immediately before treatment, within the range of from about 8% to about 30% and, most preferably, within the range of from about 10% to about 14%. The filler, immediately before treatment, is preferably at ambient temperature and it is preferred that the entire process be conducted at atmospheric pressure.
