  • Tobacco Reconstitution
    Patent number: 5562108
    Abstract: In a process of tobacco reconstitution by extrusion a mixture of tobacco, starch and binder, with the addition of water, is extruded as a web. The extrudate is drawn down, whereby the thickness of the web is reduced. A minor proportion of the binder, which may be carboxymethyl cellulose, is fed to the extruder barrel in aqueous solution. This has the effect of increasing the tensile strength of the web, so that the web can be drawn down to a greater degree.
