In some embodiments, tobacco cut filler based on the invention could additionally be used in the tobacco rod of a combustible smoking article, such as a filter cigarette, cigarillo or cigar. Alternatively, the cut filler may be used to offer Filling cut tobacco the tobacco aerosol producing substrate in a distillation based smoking article, or an electrically heated smoking system. Alternatively, the reduce filler may be used as a roll-your-own or make-your-own product, or loose tobacco product to be used in a pipe.
The term “cut specification” is used all through the specification to refer to the various geometric parameters characterising the strips obtained by subjecting a tobacco material to a chopping operation. Thus, in accordance to a given “cut specification”, a tobacco material shall be minimize or shredded into strips having a predetermined cut width, minimize length, minimize shape and so forth. Further, it will be desirable to provide one such improved course of that enables for a greater control of the shape, size and properties of the reconstituted tobacco matter forming part of the cut filler. At the same time, it might be desirable to offer one such course of that doesn’t require any major modification of the conventional apparatus and services used within the main therapy of tobacco.
A tobacco cut filler in accordance with any one of many previous claims, wherein the first tobacco material is a reconstituted tobacco sheet. Preferably, the reduce filler has a filling energy of at least about 3.5 cubic centimetres per gram at a reference moisture worth of 12.5 p.c oven volatiles. More preferably, the cut filler has a filling energy of a minimum of about 4 cubic centimetres per gram at a reference moisture value of 12.5 p.c oven volatiles. In addition, or as an alternative, the cut filler ideally has a filling power of lower than about 8 cubic centimetres per gram at a reference moisture worth of 12.5 percent oven volatiles.
In most popular embodiments, the primary tobacco material is shredded into strips from a sheet materials having a thickness from about 0.05 mm to about 1 mm. Even extra ideally, the primary tobacco materials is shredded into strips from a sheet materials having a thickness from about 0.1 mm to about 0.three mm, most preferably from a sheet material having a thickness of about 0.2 mm. A tobacco cut filler in accordance with any certainly one of claims 1 to 9, whereby the first tobacco material is shredded into strips every comprising no less than a primary strip structure 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 including a number of V-shaped construction. Each V structure contains two considerably straight components forming an angle.
Figures 1 to 12 exhibits reduce strips of a primary tobacco materials for incorporation in a reduce filler in accordance with the current invention. The strips have been reduce from a sheet of reconstituted tobacco having a thickness from about 0.05 mm to about 1 mm in accordance with a primary reduce tobacco pipe specification, whereby the primary minimize specification units a predetermined first cut width CW1 and a predetermined first cut length CL1 . In addition, the primary cut specification may additional set a predetermined first sectional reduce width SCW1.
A tobacco cut filler in accordance with any one of many preceding claims, wherein the first tobacco materials is shredded into strips having a minimize size from about 5 mm to about 60 mm. A tobacco reduce filler in accordance with any considered one of claims 2 to 4, whereby the second tobacco materials is a pure tobacco leaf material. An angle of 90 degrees was thought of to be undesirable, in that it will lead primarily to a form fairly just like the shape of Figure 6, and so an angle of 60 levels was chosen for the “V” elements. Further, the tactic ideally comprises the step of blending the cut first tobacco material and the cut second tobacco material.
The expressions “last cut width” and “final cut length” are used herein to describe the reduce width and minimize length of a tobacco material as found in a tobacco minimize filler utilized in a tobacco product. The technique may further comprise a step of conditioning the first tobacco material previous to chopping the primary tobacco materials. Further, the tactic may comprise a step of controlling the moisture content of the reduce filler by adjusting the moisture content of the first tobacco materials.
Reconstituted tobacco is formed from tobacco materials such as tobacco stems, tobacco stalks, leaf scraps and tobacco mud, which are produced during the manufacturing processes of tobacco products. Such tobacco materials might, for instance, be ground to a fine powder and then combined with water and usually with a binder, corresponding to guar gum, to type a slurry. This slurry is then forged onto a supportive surface, corresponding to a belt conveyor, and dried to form a sheet (so referred to as ‘cast leaf) that can be faraway from the supportive floor and wound into bobbins.
By contrast, in a multimodal distribution, the likelihood mass operate has a number of maxima, which signifies that among the many minimize strips of the first tobacco material there are multiple values of cut length that occur most often. In the context of the present specification, a distribution having a quantity of native maxima is considered multimodal. It shall be appreciated that the different modes in a multimodal distribution may have completely different frequencies, such that, among the many minimize strips of the first tobacco materials, one modal value of cut length will happen extra frequently than one other modal worth.
