Abstract
A method of plumping cut tobacco includes impregnating the cut tobacco with an adjuvant plumping agent and forcing the adjuvant plumping agent to expand in order to inflate the tissues of cut tobacco (plumping step), idly storing the plumped tobacco with a low moisture content level (idle storage step) and remoisturizing the cut tobacco after the idle storage step by adding moisture to achieve a predetermined final moisture content level (moisture content regulating step). With such a method, cut tobacco can be remarkably plumped before it is used for cigarette production.
