According to a side of the current invention, there is offered a tobacco minimize filler comprising a first tobacco material reduce in accordance with a primary reduce specification, wherein the first minimize specification sets at least predetermined first cut width and first reduce length. U.S. Patent 6,568,104 assigned to Philip Morris Inc., New York, New York, USA. A process for preparing tobacco stem for use as filler for a smoking article consists of classifying the green tobacco stem by diameter to provide a plurality of stem grades and rolling each grade individually. Each grade is rolled underneath rolling conditions optimized for that grade together with rolling the grade through the nip between rollers with the nip measurement being adjusted for each grade in order to achieve a uniform rolled stem thickness and the oven volatiles content of the stem being adjusted before the rolling.
The values of filling power are expressed by method of corrected cylinder volume which is the cylinder volume of the tobacco material at a reference moisture level of 12.5 p.c oven volatiles. The cylinder volume could additionally be determined using 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 describe a cut strip of tobacco materials shaped considerably like a portion of a sine wave.
In some embodiments, tobacco cut filler in accordance with the invention could additionally be used in the tobacco rod of a flamable smoking article, such as a filter cigarette, cigarillo or cigar. Alternatively, the cut filler could additionally be used to supply the tobacco aerosol producing substrate in a distillation based mostly smoking article, or an electrically heated smoking system. Alternatively, the reduce filler could additionally be used as a roll-your-own or make-your-own product, or free tobacco product to be used in a pipe.
In preferred embodiments, the primary tobacco material is a pre-processed tobacco materials. By “pre-processed tobacco materials” reference is made all through the specification to a tobacco materials produced by man from natural tobacco as opposed to occurring naturally as such. It would therefore be fascinating to offer another tobacco minimize filler having improved filling power. At the identical time, it will be desirable to offer a novel course of for manufacturing tobacco cut filler, whereby the filling power of the tobacco cut filler is improved and the manufacturing of tobacco dust is reduced. The current invention pertains to the manufacturing of tobacco minimize filler comprising reconstituted tobacco and to a smoking article formed from a tobacco rod comprising the reduce filler based on the invention.
These irregular items are meant to be comparable in dimension to tobacco lamina, such that they are often blended with the tobacco lamina and cut. In particular, the blend is often minimize into particles having a predetermined minimize width. However, as a end result of the reconstituted tobacco sheet is quite randomly ripped into pieces, the tobacco fibres are generally not aligned in a uniform path. Tobacco rods were prepared from a tobacco cut filler utilizing tobacco particles minimize in accordance with the specs of Figures 1 1 and 12. In particular, a primary couple of blends have been used, that contained eighty five percent by weight of natural tobacco particles and 15 % by weight of reconstituted tobacco particles reduce in accordance with specs of Figures 1 1 and 12, respectively.
Should one such particle break at a location within the central V-shaped portion, the two resulting parts of the particles would nonetheless be effectively V-shaped. The highest CCV values had been obtained for reduce specification no. 3, which substantially corresponds to particles having a Y-shape. However, it was discovered that when particles were produced from the identical sheet of reconstituted tobacco according to minimize specification no. three are produced, a significant fraction of the tobacco material went to waste. These correspond to the shapes illustrated in Figures 9 and 10, respectively, for which the values of CCV listed within Fashion tobacco pipe the following Table 3 were measured. Tobacco cut fillers based on the present invention could additionally be prepared by a way comprising offering a primary tobacco materials and slicing the primary tobacco material in accordance with a first cut specification setting at least predetermined first cut width and first minimize size. Tobacco reduce filler in accordance with the present invention could additionally be included into a variety of smoking articles.
A tobacco cut filler based on declare 1 or 2, wherein the first tobacco material is a pre- processed tobacco materials. In a 3rd experiment, the cut specification no. 10 was barely modified with a view to bettering the resistance of the particles to the stresses concerned by the cigarette-making process. In explicit, there was concern that during the cigarette-making process the tobacco particle can be uncovered to excessive tensions and frictions which might trigger particles prepared in accordance with the cut specification no. 10 to break. This may have lowered the benefit coming from the V-shape and shown by the CCV measurements described above. Figure thirteen depicts a schematic view of an apparatus for forming a tobacco reduce filler in accordance with the current invention. Figures depict several examples of significantly shapes into which tobacco material for forming a cut filler in accordance with the present invention may be cut.
The yield of flat rolled stem which may be used instantly as filler is increased, and the common stem length and thus the average size of minimize filler from stem is elevated. A tobacco cut filler based on any one of many preceding claims having a filling energy of no less than three.5 cubic centimetres per gram at a reference moisture value tobacco pipe of 12.5 p.c oven volatiles. Accordingly, tobacco particles had been ready from the identical sheet of reconstituted tobacco based on the minimize specification illustrated in Figure 12, wherein the reduce width SCW1 is of 0.9 millimetres, the minimize size CL1 is of 4.ninety four millimetres and the worldwide width CW1 is of 12.50 millimetres.
More ideally, the primary tobacco material is shredded into strips having a minimize width of lower than about zero.ninety five mm. Even extra preferably, the first tobacco material is shredded into strips having a cut width of less than about zero.9 mm. In most popular embodiments, the primary tobacco materials is shredded into strips having a minimize width from about zero.2 mm to about 1 mm. Preferably, the second tobacco material is a pure tobacco leaf materials.
Suitable natural tobacco leaf materials include tobacco lamina, tobacco stem material and tobacco stalk materials. The natural tobacco leaf materials used because the second tobacco material might embody any kind of tobacco leaf, including for example Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a combination thereof. A tobacco minimize filler based on the present invention comprises a primary tobacco material cut in accordance with a primary minimize specification, whereby the first minimize specification sets a minimum of predetermined first cut width and first reduce size. The time period “filling energy” is used to describe the amount of space taken up by a given weight or mass of a tobacco materials. The larger the filling energy of a tobacco material, the decrease the burden of the material required to fill a tobacco rod of normal dimensions.
