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 degree of 12.5 p.c oven volatiles. The cylinder quantity may be determined using a Borgwaldt densimeter DD60 or DD60A type 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 material formed considerably like a portion of a sine wave.
Sensors forty and mass flow controllers forty two, forty four, if current, are operatively connected with a control unit 46 configured to control the operation of the equipment. In specific, the control unit 46 adjusts the pace to the conveyor belt 38 in view of variations in the pace at which the online of reconstituted tobacco is fed to the shredding gadget 36, in order to forestall any undesirable accumulation of cut strips on the conveyor belt. By finely controlling the size and form of the strips into which the first tobacco material is reduce or shredded, the options of the primary tobacco material can advantageously be better preserved each time the first tobacco materials is mixed, in the shredded state, with another tobacco materials. This is especially advantageous when the primary tobacco materials is a pre-processed tobacco materials, corresponding to a reconstituted tobacco sheet materials. The “thickness” of a cut strip of tobacco materials for incorporation in reduce fillers according to the current invention refers to the distance between an higher surface and a lower surface of the portion of fabric forming the minimize strip.
In most well-liked embodiments, the first tobacco materials is shredded into strips from a sheet material having a thickness from about 0.05 mm to about 1 mm. Even more ideally, the first tobacco material is shredded into strips from a sheet material having a thickness from about 0.1 mm to about 0.three mm, most preferably from a sheet material having a thickness of about zero.2 mm. A tobacco cut filler in accordance with any considered one of claims 1 to 9, whereby the first tobacco pipe tobacco material is shredded into strips each comprising at least a primary strip structure comprising a branching node from which an extra strip structure branches off, forming an angle with the first strip structure. Figures 10 and 12 present two examples of reduce strips including one or more V-shaped structure. Each V construction comprises two substantially straight components forming an angle.
More preferably, the first tobacco materials is shredded into strips having a minimize width of lower than about 0.ninety five mm. Even more preferably, the primary tobacco material is shredded into strips having a cut width of lower than about zero.9 mm. In most well-liked embodiments, the first tobacco material is shredded into strips having a minimize width from about zero.2 mm to about 1 mm. Preferably, the second tobacco material is a natural tobacco leaf material.
The time period “cut 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 chopping operation. Thus, in accordance to a given “cut specification”, a tobacco materials shall be cut or shredded into strips having a predetermined minimize width, minimize length, reduce shape and so forth. Further, it would be desirable to supply one such improved course of that permits for a greater control of the form, dimension and properties of the reconstituted tobacco matter forming a half of the minimize filler. At the same time, it might be fascinating to supply one such process that does not require any main modification of the traditional apparatus and facilities used within the primary remedy of tobacco.
Without wishing to be certain to theory, it will be appreciated that in any slicing, rolling or extruding operation, the tobacco fibres generally align in a given path, which may thus be recognized because the longitudinal direction of the tobacco material. The “minimize length” of a minimize strip of tobacco material for incorporation in minimize fillers in accordance with the current invention might due to this fact be measured alongside the principle path of fibre alignment, which generally corresponds to the longitudinal direction. Thus, the cut Fashion tobacco pipe length of a person reduce strip can be accurately measured using a conventional measuring system beneath a microscope. In a traditional course of, reconstituted tobacco or tobacco stem materials or each are typically blended with threshed tobacco lamina to bear a collection of treatments, corresponding to conditioning and drying. To this purpose, a reconstituted tobacco sheet is typically ripped into randomly shaped sheet-like pieces having a non-uniform dimension, generally of several sq. centimetres.
