Experiments had been carried out in order to assess the impression of various shapes and cut specs to key parameters of tobacco reduce filler particles, such because the filling power. In more element, Figure 1 shows a zigzag-shaped strip and Figure 2 shows a wave-shaped strip. Where the cut strip is zigzag-shaped or wave- formed, it is potential to measure a wave length of the cut strip, which considerably corresponds to the strip reduce length divided by the number of repetitions of the zigzag or wave. For occasion, within the cut 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 ideally from about 2 mm to about 12 mm, much more preferably from 4 mm to 10 mm. Preferably, the tobacco reduce filler further contains a second tobacco materials reduce in accordance with a second reduce specification differing from the first reduce specification for no less than certainly one of minimize length and minimize width.
More preferably, the reduce filler has a filling power of lower than about 7 cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles. In some particularly most popular embodiments, the cut filler has a filling power of from about 3.5 cubic centimetres per gram to about eight cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles. Preferably, the first tobacco material is shredded into strips having a minimize size of at least about 5 mm. More preferably, the primary tobacco material is shredded into strips having a reduce length of at least about 10 mm.
Before every measurement was taken, tobacco particles reduce in accordance with the assorted cut specs have been stored in a conditioned room for 24 hours. For each specification, three measurements of the CCV were taken on the 5 samples, and then the total common was calculated and assumed as the effective CCV of the specification. Between repetitions of the measurements, the samples had been 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 reduce length distribution among the reduce strips of the first tobacco materials is preferably unimodal.
A tobacco minimize filler in accordance with any one of many preceding claims, whereby the primary tobacco materials is a reconstituted tobacco sheet. Preferably, the reduce filler has a filling energy of a minimum of about three.5 cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles. More preferably, the reduce filler has a filling power of at least about four cubic centimetres per gram at a reference moisture worth of 12.5 % oven volatiles. In addition, or in its place, the cut filler preferably has a filling energy of lower than about eight cubic centimetres per gram at a reference moisture value of 12.5 % oven volatiles.
These irregular items are supposed to be similar in measurement to tobacco lamina, such that they can be blended with the tobacco lamina and reduce. In specific, the mix is usually reduce into particles having a predetermined reduce width. However, because the reconstituted tobacco sheet is rather randomly ripped into items, the tobacco fibres are usually not aligned in a uniform course tobacco pipe. Tobacco rods had been ready from a tobacco minimize filler utilizing tobacco particles cut in accordance with the specifications of Figures 1 1 and 12. In particular, a first couple of blends were used, that contained 85 p.c by weight of pure tobacco particles and 15 percent by weight of reconstituted tobacco particles reduce in accordance with specs of Figures 1 1 and 12, respectively.
