The invention provides a method for improving cigarette
soot whiteness. Tobacco raw materials include mature tobacco with the
potassium-
chlorine ratio large than 4, and
papermaking process reconstituted tobacco at least accounting for 5% of the tobacco raw materials. Finished product tobacco is obtained by conducting vacuum
moisture regaining, loose
moisture regaining, screening and casing, shredding, the leaf and tobacco temperature increase procedure before
drying, the leaf and tobacco
drying procedure, leaf and tobacco
winnowing and perfuming. A
collimator of the appropriate specification is selected to conduct cigarette rolling on finished product
cut tobacco, and it is ensured that the
density change rate of finished product tobacco distribution at the ends and in the middles of the cigarettes is smaller than 11.5%. By controlling the cigarette production process, finished product
cut tobacco can have the appropriate
moisture content, an appropriate filling value and appropriate elasticity, and the problem that the tobacco
combustibility is poor is solved; by selecting cigarette
rolling paper matched with
cut tobacco and controlling relatively-low-weight cigarettes,
combustion of smoked cut tobacco of cigarettes is more complete, the cigarette
soot whiteness is obviously improved, and the
tar release amount and the
CO release amount are decreased.
