  • Tobacco processing
    Patent number: 5012823
    Abstract: A method and apparatus are disclosed for applying foamed material to tobacco, and for drying and setting the foamed material, particularly in connection with the making of cigarettes. The foamed material may be added to the tobacco, for example, in the paper guide section of a cigarette maker, at the garniture mouth or through the short tongue or through both, or at the chimney. Drying and setting can occur in the chimney, on the vacuum belt, or in the garniture, after the material has been applied to the tobacco filler. Drying can be accomplished, for example, by using heated air or microwave radiation. Addition of material to tobacco filler, during the cigarette making process in the form of a foam, results in a cigarette in which the material added is more uniformly distributed.
