The term “reduce specification” is used all through the specification to discuss with the assorted geometric parameters characterising the strips obtained by subjecting a tobacco materials to a slicing operation. Thus, in accordance to a given “reduce specification”, a tobacco material shall be minimize or shredded into strips having a predetermined cut width, minimize size, minimize form and so forth. Further, it will be fascinating to supply one such improved process that allows for a better management of the form, measurement and properties of the reconstituted tobacco matter forming a half of the reduce filler. At the identical time, it might be fascinating to provide one such course of that doesn’t require any main modification of the conventional equipment and facilities used in the major remedy of tobacco.
Even more ideally, first tobacco materials is shredded into strips having a cut length of no much less than about 15 mm. In addition, or in its place, the first tobacco material is preferably shredded into strips having a minimize size of less than about 60 mm. More ideally, the first tobacco material is shredded into strips having a minimize size of lower than about 50 mm. Even more preferably, the primary tobacco materials is shredded into strips having a cut length of lower than about 40 mm. In most popular embodiments, the first tobacco materials is shredded into strips having a minimize size from about 5 mm to about 60 mm. The time period “sectional cut width” is used in the present specification to describe the side- to-side width of 1 such portion of a minimize strip of tobacco material.
More ideally, the first tobacco materials is shredded into strips having a reduce width of less than about zero.95 mm. Even more ideally, the primary tobacco material is shredded into strips having a reduce width of less than about zero.9 mm. In most popular embodiments, the first tobacco materials is shredded into strips having a cut width from about 0.2 mm to about 1 mm. Preferably, the second tobacco materials is a pure tobacco leaf material.
Conventionally, minimize filler tobacco merchandise for smoking articles are fashioned predominantly from the lamina portion of the tobacco leaf, which is separated from the stem portion of the leaf during a threshing course of. Much of the stem portion that remains after the lamina has been removed and separated is not used. However, it is not unusual to add some tobacco stems back into the cut filler along with the lamina.
In preferred embodiments, the primary tobacco materials is shredded into strips from a sheet materials having a thickness from about zero.05 mm to about 1 mm. Even more ideally, the primary tobacco materials is shredded into strips from a sheet material having a thickness from about 0.1 mm to about zero.three mm, most preferably from a sheet materials having a thickness of about zero.2 mm. A tobacco minimize filler according to any one of claims 1 to 9, wherein the first tobacco pipe tobacco materials is shredded into strips each comprising no less than a first strip construction comprising a branching node from which a further strip construction branches off, forming an angle with the primary strip structure. Figures 10 and 12 present two examples of minimize strips together with one or more V-shaped construction. Each V structure comprises two substantially straight components forming an angle.
Suitable pure tobacco leaf supplies embrace tobacco lamina, tobacco stem material and tobacco stalk materials. The natural tobacco leaf materials used as the second tobacco materials could include any kind of tobacco leaf, together with for instance Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a combination thereof. A tobacco reduce filler in accordance with the current invention includes a first tobacco material minimize in accordance with a primary minimize specification, wherein the primary cut specification units no much less than predetermined first reduce width and first minimize size. The term “filling power” is used to explain the amount of house taken up by a given weight or mass of a tobacco materials. The higher the filling energy of a tobacco material, the lower the load of the material required to fill a tobacco rod of normal dimensions.
The yield of flat rolled stem which may be used instantly as filler is increased, and the common stem length and thus the common length of cut filler from stem is elevated. A tobacco reduce filler based on any one of the preceding claims having a filling energy of no much less than 3.5 cubic centimetres per gram at a reference moisture worth of 12.5 p.c oven volatiles. Accordingly, tobacco particles were ready from the same sheet of reconstituted tobacco based on the cut specification illustrated in Figure 12, wherein the reduce width SCW1 is of zero.9 millimetres, the minimize size CL1 is of 4.ninety four millimetres and the worldwide width CW1 is of 12.50 millimetres.
A tobacco minimize filler according to any one of the preceding claims, whereby the primary tobacco material is shredded into strips having a cut length from about 5 mm to about 60 mm. A tobacco minimize filler in accordance with any one of claims 2 to four, whereby the second tobacco materials is a pure tobacco leaf materials. An angle of ninety degrees was thought of to be undesirable, in that it will lead primarily to a form quite much like the form of Figure 6, and so an angle of 60 levels was chosen for the “V” components. Further, the strategy preferably contains the step of blending the cut first tobacco material and the minimize second tobacco material.
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 discuss with a web, ideally with considerably uniform thickness, that could be produced by the rolling or casting of an aqueous slurry or pulp shaped Fashion tobacco pipe from tobacco particles by certainly one of a number of methods recognized within the art. Suitable by-products embrace tobacco stems, tobacco stalks, leaf scraps, and tobacco mud produced through the manufacturing course of.
