ABSTRACT:
Whole tobacco stems are converted to expanded tobacco particles by opening the cellular structure of the stems and moisturizing the stems by the simultaneous application of water and steam. The stems, at a first induced moisture content of from 20 to 40% are then subjected to an equilibration step where the moisture content of the stem is uniformly distributed within the stems. The equilibrated stems are thereafter moisturized to a second induced moisture content by first an application of water and thereafter the simultaneous application of water and steam. At the second induced moisture content of from 30 to 60% the stems are cut into a plurality of particles that are thereafter expanded and dried to a final moisture content of from 13 to 25%.
