Abstract
A method of expanding tobacco involves introducing a steam flow and a tobacco material into a duct having an inlet and an outlet and defining an arcuate flow path. The tobacco is entrained in the steam flow and conveyed along the arcuate flow path and toward the outlet. The presence of the steam results in volumetric expansion of the tobacco as the steam and entrained tobacco travel along the flow path. The steam and entrained tobacco are then collected and separated. As such, an expanded tobacco is provided.
