A tobacco cut filler based on any one of the preceding claims, wherein the primary tobacco materials is a reconstituted tobacco sheet. Preferably, the cut filler has a filling energy of a minimal of about 3.5 cubic centimetres per gram at a reference moisture value of 12.5 percent oven volatiles. More ideally, the cut tobacco pipe filler has a filling power of no less than about four cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles. In addition, or instead, the minimize filler preferably has a filling power of lower than about 8 cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles.
The expressions “last cut width” and “last cut length” are used herein to explain the reduce width and reduce length of a tobacco materials as found in a tobacco reduce filler utilized in a tobacco product. The method might additional comprise a step of conditioning the primary Fashion tobacco pipe tobacco materials previous to chopping the first tobacco material. Further, the strategy might comprise a step of controlling the moisture content material of the reduce filler by adjusting the moisture content of the primary tobacco materials.
The values of filling energy 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 % oven volatiles. The cylinder volume could additionally be decided utilizing a Borgwaldt densimeter DD60 or DD60A sort Filling cut tobacco fitted with a measuring head for cut tobacco and a tobacco cylinder container. The term “sinusoidal” is used to explain a cut strip of tobacco materials formed substantially like a portion of a sine wave.
Experiments have been carried out in order to assess the impact of various shapes and minimize specifications to key parameters of tobacco cut filler particles, such as the filling energy. In more element, Figure 1 exhibits a zigzag-shaped strip and Figure 2 exhibits a wave-shaped strip. Where the reduce strip is zigzag-shaped or wave- shaped, it’s attainable to measure a wave length of the minimize strip, which substantially corresponds to the strip minimize length divided by the variety of repetitions of the zigzag or wave. For occasion, in the minimize strip of Figure 1 the zigzag is repeated 10 occasions. 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 4 mm to 10 mm. Preferably, the tobacco reduce filler additional includes a second tobacco material cut in accordance with a second cut specification differing from the first reduce specification for at least considered one of cut size and minimize width.
More preferably, the cut filler has a filling power of less than about 7 cubic centimetres per gram at a reference moisture value of 12.5 percent oven volatiles. In some significantly most popular embodiments, the reduce 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 first tobacco material is shredded into strips having a reduce length of a minimal of about 5 mm. More ideally, the primary tobacco materials is shredded into strips having a minimize size of no less than about 10 mm.
Reconstituted tobacco is fashioned from tobacco material such as tobacco stems, tobacco stalks, leaf scraps and tobacco mud, which are produced through the manufacturing processes of tobacco products. Such tobacco material might, for instance, be floor to a fantastic powder and then mixed with water and sometimes with a binder, such as guar gum, to kind a slurry. This slurry is then cast onto a supportive surface, such as a belt conveyor, and dried to type a sheet (so called ‘solid leaf) that can be removed from the supportive surface and wound into bobbins.
