Abstract
Reconstituted tobacco sheet having improved homogeneity and wet and dry tensile strength are produced by a process including mixing a water-soluble polysaccharide and a humectant under a first high shear; subjecting the resulting aqueous binder composition to a second high shear mixing operation; mixing the resulting aqueous binder composition with tobacco dust under a third shear, the third shear being lower than the first and second shears to form a slurry; casting the slurry onto a supportive surface such as a stainless steel conveyor belt; drying the cast slurry to form a reconstituted tobacco sheet; and recovering the reconstituted tobacco sheet for use such as cut filler for cigarettes.
