Alternative methods for the manufacture of reconstituted tobacco sheets are additionally known to the skilled individual. Throughout this specification, the expression “reconstituted tobacco sheet” is used to refer to an internet, ideally with substantially uniform thickness, which could be produced by the rolling or casting of an aqueous slurry or pulp fashioned tobacco pipe from tobacco particles by certainly one of several strategies identified in the art. Suitable by-products embrace tobacco stems, tobacco stalks, leaf scraps, and tobacco mud produced in the course of the manufacturing course of.
Even more ideally, the primary tobacco materials is shredded into strips from a sheet materials having a thickness of no much less than about 0.2 mm. In addition, or in its place, the primary tobacco materials is ideally shredded into strips from a sheet materials having a thickness of lower than about 1 mm. More ideally , the primary tobacco materials is shredded into strips from a sheet material having a thickness of less than about 0.95 mm. Even extra preferably, the primary tobacco materials is shredded into strips from a sheet materials having a thickness of lower than about 0.eighty five mm.
For instance, a bimodal distribution may correspond effectively to two teams of cut strips having completely different average minimize lengths , one group being larger than the opposite. Preferably, the first tobacco materials is shredded into strips from a sheet materials having a thickness of at least about 0.05 mm. More preferably, the primary tobacco materials is shredded into strips from a sheet material having a thickness of at least about zero.1 mm.
The term “cut specification” is used throughout the specification to refer to the various geometric parameters characterising the strips obtained by subjecting a tobacco material to a slicing operation. Thus, in accordance to a given “reduce specification”, a tobacco materials shall be cut or shredded into strips having a predetermined reduce width, reduce size, cut shape and so forth. Further, it would be desirable to offer one such improved course of that enables for a greater management of the form, size and properties of the reconstituted tobacco matter forming a half of the reduce filler. At the same time, it would be fascinating to supply one such course of that doesn’t require any main modification of the standard apparatus and services used in the main remedy of tobacco.
In addition, a second couple of blends was used, that contained 70 p.c by weight of pure tobacco particles and 30 % by weight of reconstituted tobacco particles cut in accordance with the specifications of Figures 1 1 and 12, respectively. Thus, the minimize width of an individual reduce strip is taken on the point along the size of the strip that yields the biggest cross-sectional area. Further, the filling power of the shredded first tobacco materials may be maximised by choosing an appropriate first reduce specification. This results in an improved filling energy of the cut filler as a complete, particularly when the primary tobacco materials is mixed with at least another tobacco material.
According to an aspect of the present invention, there may be supplied a tobacco reduce filler comprising a primary tobacco material reduce in accordance with a primary reduce specification, wherein the first minimize specification units at least predetermined first reduce width and first cut length. U.S. Patent 6,568,104 assigned to Philip Morris Inc., New York, New York, USA. A course of for preparing tobacco stem to be used as filler for a smoking article contains classifying the green tobacco stem by diameter to provide a plurality of stem grades and rolling every grade individually. Each grade is rolled beneath rolling situations optimized for that grade together with rolling the grade through the nip between rollers with the nip size being adjusted for each grade in order to attain a uniform rolled stem thickness and the oven volatiles content of the stem being adjusted before the rolling.
Suitable pure tobacco leaf materials embrace tobacco lamina, tobacco stem material and tobacco stalk materials. The pure tobacco leaf material used as the second tobacco materials might include any type of tobacco leaf, together with for instance Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mixture thereof. A tobacco cut filler based on the present invention comprises a first tobacco material minimize in accordance with a first cut specification, wherein the first minimize specification sets no much less than predetermined first reduce width and first cut size. The time period “filling power” is used to describe the volume of area taken up by a given weight or mass of a tobacco materials. The higher the filling energy of a tobacco materials, the lower the load of the material required to fill a tobacco rod of standard dimensions.
