Definitions

  • the present invention relates to an apparatus for threshing tobacco leaf material and to a process of threshing tobacco leaf material using the apparatus.
  • the tobacco leaf In the tobacco industry, it is well known, that in order to process the tobacco into a suitable form for use in the manufacturing of products, the tobacco leaf has to have the midrib stem removed from the rest of the tobacco leaf.
  • WO 98/26677 describes a machine for tobacco threshing in which the tobacco is not all forced through a fixed screen but instead the threshing rotor and two feeding rotors are mounted inside a rotating drum and the tobacco can pass down the drum through the rotors without being forced through a screen. Whilst this has the advantage over current processes in that it will generate less small-sized lamina pieces as waste, it does not produce a significantly greater lamina size.
  • Tognana describes a threshing mill in which some of the tobacco is not forced through a screen with the intention that this will produce pieces of tobacco with a larger particle size.
  • the type and speed of the beaters described in this patent are similar to those found in a conventional thresher.
  • the aim of the present invention is to provide a means for threshing tobacco leaf material to obtain pieces of tobacco lamina, the majority of which are of a large particle size.
  • the present invention provides an apparatus for threshing tobacco comprising a housing having an upper entrance for charging tobacco leaves or parts thereof to the housing and a lower exit for discharging threshed tobacco from the housing and, located within the housing, a first rotatable stripping means having a plurality of radially extending elements each presenting a leaf puncturing tip for puncturing the lamina of a tobacco leaf and means for rotating the rotatable stripping means, the housing and the stripping means being arranged such that, in use, the leaf puncturing tip of a radially extending element on the stripping means as it rotates punctures the lamina of a tobacco leaf, or part thereof, entering into the housing through the upper entrance thereof and effects a slashing action on the lamina during the downward movement of the leaf, or part thereof, through the housing so as to separate at least partially the lamina from the stem of the leaf.
  • threshing efficiency which is defined as the amount of free tobacco lamina that is removed from the tobacco leaf relative to the total amount of lamina available.
  • particle size or particle size distribution
  • a further criterion is the number of impacts to which the tobacco is subjected in order to achieve a particular threshing efficiency and/or particle size.
  • the threshing apparatus of the invention which does not require a basket, is able to achieve a relatively high threshing efficiency by a single impact or a controlled number of impacts by the radially extending elements to produce lamina pieces of large size and a particle size distribution which has a high proportion of lamina pieces of relatively large size and a small proportion of pieces of relatively small size.
  • some tobacco will, unfortunately, be subjected to a greater number of impacts by the rotating elements than is necessary with the inevitable result that more smaller pieces of lamina than is desired are produced.
  • the apparatus comprises rotatable stripping means located within a housing.
  • the axis of rotation of the rotatable stripping means may be tilted at from 0° to 10° to the horizontal but preferably, will be substantially horizontal.
  • the stripping means has a plurality of radially extending elements each presenting a leaf puncturing tip.
  • the radially extending elements may be radially extending plates, teeth, blades or flexible arms, for example continuous plates, single or multiple spaced teeth which may be straight, bent or curved, knives and spines, which may be flexible.
  • the radially extending elements are blades which according to a particularly preferred embodiment are L-shaped with the bend in the intended direction of rotation of the stripping means.
  • the radially extending elements each present a leaf puncturing tip for puncturing the lamina of tobacco leaf material.
  • the leaf puncturing tip may comprise a single sharpened projection at the tip of the radially extending element or, alternatively, may comprise a saw-tooth projection at the tip of the radially extending element.
  • each individual tooth will typically have a depth to pitch ratio in the range of from 1:1 to 2:1, for instance, having a depth to pitch ratio of 2:1 , such as one having a depth of 1 inch and a pitch of about 0.5 inch or, alternatively, the depth may be foreshortened in such a way as to eliminate the pinch point at the base of the teeth and thus reduce the propensity of the blade to clogging.
  • stator element which typically is fixed to or mounted on the internal wall of the housing in which the stripping means is located.
  • the stator element extends into the housing such that it co-operates with the radially extending elements provided on the rotatable stripping means.
  • the position of any stator element in relation to the position of the radially extending elements on the rotatable stripping means is such that as the rotatable stripping means rotates in the housing the leaf puncturing tips intermesh with the stator element to improve the puncturing performance of the tips and to create shearing forces that apply to the tobacco leaf material caught between the stator element and the leaf puncturing tips.
  • the distance between the stator element and the leaf puncturing tip is typically less than 100mm.
  • the housing is preferably in the form of a substantially vertical tower providing a substantially vertical chute for introducing the tobacco leaves to the stripping means.
  • the stripping means is typically in the form of a rotatable cylindrical element having an axis of rotation coincidental with the horizontal axis of a drum-like chamber provided in the housing from which rotatable cylindrical element the radially extended elements radiate outwardly towards the internal surfaces of the drum-like chamber along the length of the rotatable cylindrical element.
  • the drum-like chamber will have an internal diameter which is slightly greater than the total diameter of the stripping means, typically in the range of from 12 to 30 inches (30 to 77cm), preferably in the range of from 18 to 24 inches (45 to 61cm) and will have a length of several feet, typically about 6 to 7 feet (1.8 to 2.2m) in length.
  • the radially extending elements have the form of separate teeth or sharpened blades radiating outwardly from the rotatable cylindrical element of the stripping means they will be disposed separately along the length of the cylindrical element typically at a distance of from 2 to 8 inches (5 to 21cm) from each other.
  • the spacing along the cylindrical element between one such separate tooth or sharpened blade and the next one to it along the length of the cylindrical element will typically be from 3 to 6 inches (7.6 to 15.2cm).
  • the radially extending elements provided on the stripping means may, alternatively, radiate outwardly from the rotatable cylindrical element continuously along the length of the cylindrical element.
  • the total diameter of the stripping means (i.e., from tip to tip of the radially extending elements) will typically be in the range of from 12 to 30 inches (30 to 77cm) preferably in the range of from 18 to 24 inches (45 to 61cm).
  • the rotatable stripping means will, in use, be rotated at a speed of rotation typically in the range of from 400 to 1200 rpm (based on a stripping means having a total diameter of about 24 inches (61cm)). Where the radially extending elements are sharpened teeth or blades then a rotation speed in the range of 400 to 600 rpm is sufficient to achieve good separation of large lamina pieces of tobacco leaf.
  • the radially extending elements comprise conventional less sharp blades then it is preferred to use a higher rotation speed of the order of 800 to 1200 rpm. This increased speed of rotation improves the puncture performance of the puncturing tip on the radially extending element to puncture the leaf and to slash the lamina thereof in order to effect separation thereof from the leaf stem.
  • the housing contains a first rotatable stripping means, a second rotatable stripping means and means for rotating the second rotatable stripping means.
  • the second rotatable stripping means will have a plurality of radially extending elements each presenting a leaf puncturing tip for puncturing the lamina of tobacco leaf material and will be arranged in the housing such that, in use, it acts in series with the first stripping means.
  • the leaf puncturing tip of a radially extending element on the second rotatable stripping means punctures the lamina of a tobacco leaf, or part thereof, received from the first stripping means and effects a slashing action on the lamina during the downward movement of the leaf, or part thereof, through the housing so as to separate at least partially the lamina from the stem of the leaf.
  • the use of a second stripping means in series with a first stripping means improves the yield of pieces of lamina free of leaf stem material.
  • the tobacco leaf material passing from the first stripping means to the second stripping means is re-oriented, i.e., it's alignment is changed so as to present the lamina in a position more amenable to being removed from the stem in the second stripping means.
  • a tobacco leaf approaches the first stripping means with an alignment with the butt end downwards a large piece of lamina will be removed since the stripping action will tend to act inwards towards the stem.
  • the stripping action is effected on a tobacco leaf presented tip downwards the leaf will tend to tear outwards way from the stem leaving a tear in the leaf but without removing the lamina.
  • the leaf thus, remains largely intact until it is presented to a subsequent stripping means butt end downwards.
  • the amount of lamina removed from leaf stems can be increased.
  • Re-orienting of the leaf material may, typically, be achieved by transporting the tobacco leaf material from one stripping means towards a subsequent stripping means using a vibrating screen.
  • the apparatus may advantageously also contain a third and subsequent separate rotatable stripping means, in series, in a cascade. Preferably, however, not more than three separate stripping means are arranged in series since the particle size of the lamina pieces obtained will be reduced and the proportion of very small pieces and/or dust obtained will be correspondingly increased.
  • the apparatus additionally comprises in the housing a third rotatable stripping means located in the housing downstream of a second rotatable stripping means as described above and means for rotating the third stripping means.
  • the third stripping means has a plurality of radially extending elements each presenting a leaf puncturing tip for puncturing the lamina of tobacco leaf material.
  • the housing and the third stripping means being arranged such that, when the apparatus is in use, the third stripping means acts in series with the second stripping means and wherein the leaf puncturing tip of a radially extending element on the third stripping means as it rotates, punctures the lamina of the tobacco leaf, or part thereof, received from the second stripping means and effects a slashing action on the lamina during the downward movement of the leaf, or part thereof, through the housing so as to separate the lamina from the stem of the leaf.
  • a second and/or a third stripping means may act in co-operation with a suitably positioned stator element as described above.
  • the tobacco leaf material can be subjected to re-orienting as described above.
