A tobacco cut filler in accordance with any one of many preceding claims, wherein the first tobacco material is a reconstituted tobacco sheet. Preferably, the cut filler has a filling energy of a minimal of about three.5 cubic centimetres per gram at a reference moisture value of 12.5 p.c oven volatiles. More ideally, the cut Fashion tobacco pipe filler has a filling power of a minimal of about four cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles. In addition, or in its place, the minimize 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.
Where OV is the actual p.c oven volatiles of the pattern of tobacco cut filler and f is a correction factor (0.four for the check 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 at all (loose-leaf tobacco) – this form is used for Scandinavian Tobacco Group’s Norwegian RYO brand Tiedemanns. A method according to any certainly one of claims 15 to twenty, further comprising adjusting the moisture content of the second tobacco materials. A fishbone-shaped strip is proven in Figure 6, whereas Figures 7 and 8 show two embodiments of rectangular strips. Abstract The quantity of tobacco which is critical for the proper filling of a cigarette is dependent upon different factors and notably on the filling weight of tobacco rag at a given stress. Some years in the past the ”Centre d’Essais” of the SEITA developed an apparatus by which the filling weight being associated to the filling capability may be measured.
Figures 1 to 12 reveals minimize strips of a primary tobacco material for incorporation in a minimize filler in accordance with the present invention. The strips have been reduce from a sheet of reconstituted tobacco having a thickness from about zero.05 mm to about 1 mm in accordance with a first minimize specification, whereby the first reduce specification units a predetermined first minimize width CW1 and a predetermined first cut size CL1 . In addition, the first reduce specification might further set a predetermined first sectional minimize width SCW1.
Before each measurement was taken, tobacco particles cut in accordance with the varied cut specifications had been stored in a conditioned room for twenty-four hours. For every specification, three measurements of the CCV had been taken on the five samples, after which the entire common was calculated and assumed as the effective CCV of the specification. Between repetitions of the measurements, the samples have been ready by detangling the person strands, in order that any compaction occurred during the previous measurement would have as little affect as attainable on the subsequently measured CCV. In some embodiment, the reduce size distribution among the many cut strips of the first tobacco material is ideally unimodal.
More ideally, the minimize filler has a filling energy of less than about 7 cubic centimetres per gram at a reference moisture value of 12.5 percent oven volatiles. In some significantly preferred embodiments, the minimize filler has a filling power of from about three.5 cubic centimetres per gram to about eight cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles. Preferably, the primary tobacco material is shredded into strips having a minimize length of no less than about 5 mm. More ideally, the first tobacco materials is shredded into strips having a cut length of no much less than about 10 mm.
The values of filling power are expressed in phrases of corrected cylinder quantity which is the cylinder volume of the tobacco material at a reference moisture level of 12.5 percent oven volatiles. The cylinder quantity could additionally be determined using Filling cut tobacco a Borgwaldt densimeter DD60 or DD60A type fitted with a measuring head for minimize tobacco and a tobacco cylinder container. The time period “sinusoidal” is used to describe a minimize strip of tobacco material formed substantially like a portion of a sine wave.
Experiments have been carried out so as to assess the impact of various shapes and minimize specs 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 exhibits a wave-shaped strip. Where the minimize strip is zigzag-shaped or wave- shaped, it is possible to measure a wave length of the reduce strip, which considerably corresponds to the strip reduce size divided by the number 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, more preferably from about 2 mm to about 12 mm, much more preferably from four mm to 10 mm. Preferably, the tobacco cut filler further comprises a second tobacco materials reduce in accordance with a second reduce specification differing from the primary reduce specification for a minimum of certainly one of cut length and minimize width.
