Figures 1 to 12 reveals cut strips of a first tobacco material for incorporation in a reduce filler in accordance with the present invention. The strips have been cut from a sheet of reconstituted tobacco having a thickness from about 0.05 mm to about 1 mm in accordance with a first cut specification, whereby the primary minimize specification sets a predetermined first cut width CW1 and a predetermined first cut size CL1 . In addition, the primary reduce specification might further set a predetermined first sectional minimize width SCW1.
As the name implies, it is simply a mixture of totally different tobacco varieties, cuts and flavors. They are simple to fill and smoke, and have greater robustness and style selection than free minimize tobacco by itself. The first tobacco materials could also be minimize into strips having any suitable shape, together with rectangular, trapezoidal, sinusoidal, Y-shaped, X-shaped and V-shaped.
Before every measurement was taken, tobacco particles minimize in accordance with the varied minimize specifications were saved in a conditioned room for twenty-four hours. For each specification, three measurements of the CCV had been taken on the five samples, and then the total common was calculated and assumed because the effective CCV of the specification. Between repetitions of the measurements, the samples were prepared by detangling the person strands, in order that any compaction occurred during the earlier measurement would have as little affect as attainable on the subsequently measured CCV. In some embodiment, the minimize length distribution among the cut strips of the primary tobacco material is ideally unimodal.
Where OV is the precise percent oven volatiles of the pattern of tobacco minimize filler and f is a correction factor (0.4 for the test indicated). In RYO, the stem can both be separated from the lamina by hand (for hand-stripped tobacco) or the stem and lamina usually are not separated in any respect (loose-leaf tobacco) – this form is used for Scandinavian Tobacco Group’s Norwegian RYO model Tiedemanns. A method based on any one of claims 15 to twenty, additional comprising adjusting the moisture content material of the second tobacco materials Fashion tobacco pipe. A fishbone-shaped strip is proven in Figure 6, whereas Figures 7 and 8 present two embodiments of rectangular strips. Abstract The quantity of tobacco which is necessary for the proper filling of a cigarette is determined by different factors and particularly on the filling weight of tobacco rag at a given pressure. Some years in the past the ”Centre d’Essais” of the SEITA developed an equipment by which the filling weight being associated to the filling capacity could be measured.
Reconstituted tobacco is shaped from tobacco materials such as tobacco stems, tobacco stalks, leaf scraps and tobacco mud, which are produced during the manufacturing processes of tobacco merchandise. Such tobacco materials may, for instance, be ground to a fine powder and then blended with water and typically with a binder, corresponding to guar gum, to kind a slurry. This slurry is then forged onto a supportive floor, similar to a belt conveyor, and dried to type a sheet (so known as ‘cast leaf) that can be faraway from the supportive surface and wound into bobbins.
A tobacco reduce filler according to any one of the previous claims, wherein the first tobacco material is a reconstituted tobacco sheet. Preferably, the cut filler has a filling energy of a minimum of about three.5 cubic centimetres per gram at a reference moisture value of 12.5 percent oven volatiles. More preferably, the minimize filler has a filling energy of a minimum of about four cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles. In addition, or in its place, the cut filler preferably has a filling power of lower than about eight cubic centimetres per gram at a reference moisture worth of 12.5 percent oven volatiles.
In flip, the third Y-shaped construction includes a third branching node from which an oblong construction branches off. In the embodiments of both Figures 9 and 1 1 the sectional reduce width within all of the constructions forming the minimize strips is substantially constant. By way of example, in a Y-shaped strip it is attainable to establish a primary strip portion extending along a first course and a second and third strip parts extending from the first strip parts alongside diverging instructions, so that they form an angle.
Experiments had been carried out in order to assess the influence of different shapes and reduce specifications to key parameters of tobacco minimize filler particles, such as the filling energy. In more element, Figure 1 shows a zigzag-shaped strip and Figure 2 reveals a wave-shaped strip. Where the minimize strip is zigzag-shaped or wave- formed, it’s potential to measure a wave size of the minimize strip, which considerably corresponds to the strip minimize size divided by the variety of repetitions of the zigzag or wave. For instance , within the reduce strip of Figure 1 the zigzag is repeated 10 times. Preferably, a wave size of the sinusoidal shape is from about 1 mm to about 15 mm, extra preferably from about 2 mm to about 12 mm, much more preferably from four mm to 10 mm. Preferably, the tobacco reduce filler further includes a second tobacco materials reduce in accordance with a second minimize specification differing from the primary cut specification for no less than one of minimize size and reduce width.
The values of filling energy are expressed by way of corrected cylinder quantity which is the cylinder quantity of the tobacco material at a reference moisture level of 12.5 p.c oven volatiles. The cylinder volume may be decided utilizing a Borgwaldt densimeter DD60 or DD60A sort fitted with a measuring head for reduce tobacco and a tobacco cylinder container. The time period “sinusoidal” is used to explain a cut strip of tobacco material shaped substantially like a portion of a sine wave.
