Figures 1 to 12 shows reduce strips of a first tobacco materials for incorporation in a minimize filler in accordance with the current invention. The strips have been cut from a sheet of reconstituted tobacco having a thickness from about zero.05 mm to about 1 mm in accordance with a primary cut specification, wherein the primary minimize specification units a predetermined first cut width CW1 and a predetermined first minimize length CL1 . In addition, the primary reduce specification could further set a predetermined first sectional minimize width SCW1.
Suitable pure tobacco leaf materials include tobacco lamina, tobacco stem material and tobacco stalk materials. The pure tobacco leaf material used because the second tobacco materials could embody any type 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 materials cut in accordance with a primary cut specification, wherein the first reduce specification units no less than predetermined first reduce width and first cut size. The term “filling energy” is used to describe the volume of area taken up by a given weight or mass of a tobacco materials. The larger the filling energy of a tobacco material, the lower the burden of the fabric required to fill a tobacco rod of ordinary dimensions.
Sensors 40 and mass flow controllers 42, forty four, if current, are operatively linked with a control unit 46 configured to control the operation of the equipment. In specific, the control unit forty six adjusts the velocity to the conveyor belt 38 in view of variations within the velocity at which the net of reconstituted tobacco is fed to the shredding system 36, in order to forestall any undesirable accumulation of minimize strips on the conveyor belt. By finely controlling the scale and form of the strips into which the primary tobacco material is cut or shredded, the options of the first tobacco material can advantageously be higher preserved every time the primary tobacco materials is mixed, within the shredded state, with another tobacco material. This is especially advantageous when the primary tobacco material is a pre-processed tobacco material, similar to a reconstituted tobacco sheet material. The “thickness” of a reduce strip of tobacco materials for incorporation in reduce fillers in accordance with the current invention refers back to the distance between an higher floor and a decrease floor of the portion of material forming the reduce strip.
Further, the second Y-shaped structure contains a second branching node from which a rectangular structure branches off. In the embodiment of Figure 1 1 , the reduce strip includes a primary Y-shaped structure together Filling cut tobacco with a primary branching node from which a second Y-shaped construction branches off. Further, the second Y-shaped structure comprises a second branching node from which a 3rd Y-shaped structure branches off.
In most popular embodiments, the primary tobacco materials is shredded into strips from a sheet materials having a thickness from about zero.05 mm to about 1 mm. Even more ideally, the primary tobacco material is shredded into strips from a sheet materials having a thickness from about 0.1 mm to about zero.three mm, most ideally from a sheet material having a thickness of about zero.2 mm. A tobacco reduce filler according to any certainly one of claims 1 to 9, whereby the primary tobacco materials is shredded into strips every comprising a minimal of a primary strip structure comprising a branching node from which a further strip structure branches off, forming an angle with the first strip structure. Figures 10 and 12 show two examples of minimize strips including one or more V-shaped structure. Each V construction comprises two considerably straight components forming an angle.
The cut width of one such Y-shaped strip corresponds considerably to the space between the ends of the second and third strip parts as measured alongside a course perpendicular to the direction outlined by an axis of the first strip portion. Within the same Y-shaped strip, the sectional reduce width of each strip portion might as a substitute be measured alongside a path substantially perpendicular to the axis of each strip portion. In some cases, corresponding to where the reduce strip of tobacco material is substantially rectangular , the sectional reduce width and the strip cut width are the same.
The values of filling energy are expressed by means of corrected cylinder volume which is the cylinder quantity of the tobacco material at a reference moisture degree of 12.5 % oven volatiles. The cylinder quantity could additionally be determined utilizing tobacco pipe a Borgwaldt densimeter DD60 or DD60A type fitted with a measuring head for cut tobacco and a tobacco cylinder container. The time period “sinusoidal” is used to describe a cut strip of tobacco material formed substantially like a portion of a sine wave.
Experiments had been carried out to have the ability to assess the influence of various shapes and minimize specs to key parameters of tobacco cut filler particles, such as the filling power. In more detail, Figure 1 exhibits a zigzag-shaped strip and Figure 2 exhibits a wave-shaped strip. Where the reduce strip is zigzag-shaped or wave- formed, it’s potential to measure a wave length of the minimize strip, which substantially corresponds to the strip cut size divided by the number of repetitions of the zigzag or wave. For instance, in the cut strip of Figure 1 the zigzag is repeated 10 instances. Preferably, a wave size of the sinusoidal form is from about 1 mm to about 15 mm, more ideally from about 2 mm to about 12 mm, even more preferably from 4 mm to 10 mm. Preferably, the tobacco reduce filler additional contains a second tobacco materials reduce in accordance with a second cut specification differing from the first reduce specification for at least one of reduce length and reduce width.
