In preferred embodiments, the primary tobacco materials is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm. Even extra 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 cut filler according to any considered one of claims 1 to 9, whereby the first tobacco material is shredded into strips each comprising at least a first strip structure comprising a branching node from which a further strip structure branches off, forming an angle with the primary strip structure. Figures 10 and 12 present two examples of cut strips together with a number of V-shaped construction. Each V construction contains two considerably straight parts forming an angle.
Alternative strategies for the manufacture of reconstituted tobacco sheets are additionally identified to the skilled person. Throughout this specification, the expression “reconstituted tobacco sheet” is used to refer to an online, preferably with substantially uniform thickness, that could be produced by the rolling or casting of an aqueous slurry or pulp fashioned from tobacco particles by one of a number of methods identified within the artwork. Suitable by-products embody tobacco stems, tobacco stalks, leaf scraps, and tobacco dust produced in the course of the manufacturing course of.
By means of instance, tobacco stems could also be ground to a fine powder after which blended with tobacco dust, guar gum, and water to kind an aqueous slurry. This aqueous slurry could also be forged and dried to type a reconstituted tobacco sheet. As an alternate, suitable tobacco materials could additionally be combined in an agitated tank with water to acquire a pulp. This net is fed onwards to a press, where the excess water is squeezed out of the net. Figure 13 illustrates an equipment 30 for the manufacture of a tobacco cut filler in accordance with the present invention. A net 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding gadget 36.
The term “minimize specification” is used all through the specification to check with the various geometric parameters characterising the strips obtained by subjecting a tobacco material to a slicing operation. Thus, in accordance to a given “reduce specification”, a tobacco materials shall be reduce or shredded into strips having a predetermined cut width, cut length, cut shape and so forth. Further, it will be fascinating to provide one such improved course of that enables for a better management of the shape, measurement and properties of the reconstituted tobacco matter forming part of the reduce filler. At the identical time, it would be fascinating to provide one such course of that does not require any main modification of the standard equipment and facilities used within the main therapy of tobacco.
Even more ideally, the primary tobacco material is shredded into strips from a sheet materials having a thickness of at least about 0.2 mm. In addition, or in its place, the first tobacco materials is ideally shredded into strips from a sheet material having a thickness of lower than about 1 mm. More ideally, the first tobacco material is shredded into strips from a sheet material having a thickness of less than about zero.95 mm. Even extra preferably, the primary tobacco materials is shredded into strips from a sheet materials having a thickness of less than about zero.eighty five mm.
A tobacco reduce filler based on any one of many previous claims, whereby the primary tobacco materials is shredded into strips having a minimize size from about 5 mm to about 60 mm. A tobacco cut filler in accordance with any one of claims 2 to 4, wherein the second tobacco material is a natural tobacco leaf material. An angle of 90 levels was thought of to be undesirable, in that it will lead primarily to a form quite much like the shape of Figure 6, and so an angle of 60 degrees was chosen for the “V” components. Further, the method ideally includes the step of blending the reduce first tobacco materials and the minimize second tobacco material.
In most well-liked embodiments, the first tobacco materials is a pre-processed tobacco material. By “pre-processed tobacco material” reference is made throughout the specification to a tobacco materials produced by man from natural tobacco versus occurring naturally as such. It would therefore be desirable to provide an alternate tobacco minimize filler having improved filling energy. At the identical time, it will Fashion tobacco pipe be fascinating to provide a novel process for manufacturing tobacco reduce filler, whereby the filling energy of the tobacco minimize filler is improved and the manufacturing of tobacco dust is decreased. The present invention pertains to the manufacturing of tobacco reduce filler comprising reconstituted tobacco and to a smoking article formed from a tobacco rod comprising the minimize filler according to the invention.
Suitable pure tobacco leaf materials embody tobacco lamina, tobacco stem materials and tobacco stalk material. The pure tobacco leaf materials used as the second tobacco materials might embody any kind of tobacco leaf, together with for example Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a mixture thereof. A tobacco cut filler in accordance with the present invention contains a first tobacco material minimize in accordance with a primary reduce specification, wherein the primary minimize specification sets at least predetermined first minimize width and first reduce size. The time period “filling power” is used to explain the amount of area taken up by a given weight or mass of a tobacco materials. The higher the filling energy of a tobacco materials, the decrease the load of the material required to fill a tobacco rod of ordinary dimensions.
Sensors 40 and mass flow controllers forty two, forty four, if present, are operatively connected with a management unit 46 configured to manage the operation of the equipment. In specific, the control unit forty six adjusts the speed to the conveyor belt 38 in view of variations within the velocity at which the online of reconstituted tobacco is fed to the shredding gadget 36, so as to stop any undesirable accumulation of minimize strips on the conveyor belt. By finely controlling the size and shape of the strips into which the first tobacco material is cut or shredded, the options of the first tobacco materials can advantageously be better preserved every time the first tobacco material is mixed, in the shredded state, with another tobacco materials. This is especially advantageous when the primary tobacco material is a pre-processed tobacco materials, corresponding to a reconstituted tobacco sheet materials. The “thickness” of a reduce strip of tobacco materials for incorporation in cut fillers according to the current invention refers to the distance between an upper surface and a decrease floor of the portion of fabric forming the cut strip.
