Definitions

  • the invention relates to the field of tobacco preparation in the context of the production of smoking articles, in particular cigarettes. Specifically, the invention relates to a modular tobacco preparation for processing raw tobacco to produce smokable cut tobacco or cigarettes.
  • FIG. 5 A typical example of a specialized standard tobacco preparation according to the prior art is the FIG. 5 refer to.
  • the different tobaccos have individual processing lines, and each box in FIG. 5 represents a process step with associated apparatus.
  • the different apparatus are connected to conveying elements such as gutters or ribbons.
  • a process step can often be represented by different apparatus, ie the drying step can, for example, in a drum dryer or air dryer be executed.
  • the partially observed and evolutionary versatility of tobacco preparations is fundamentally opposed to the concern of standardization.
  • the WO 2006/061117 A1 discloses a method for producing shredded tobacco material in which a tobacco raw material is heated and pressurized and the heated and pressurized material is guided under relaxation through a shear gap and defibered.
  • tobacco preparation should be more compact overall in terms of space requirements and / or the time required.
  • the tobacco preparation as process but also as a device arrangement to be handled better.
  • a tobacco material is prepared by at least one extrusion process, which comprises compression with pressure and temperature increase and mechanical processing and sudden expansion drying of the material at an extruder outlet.
  • the tobacco material which serves as input material here, according to the invention comprises a tobacco laminate material.
  • the present invention may use an extrusion process to substantially accomplish the entire tobacco preparation process needed for a laminate material, that is, the highest quality tobacco material.
  • extrusion is suitable not only for the preparation of tobacco by-products, such as dust, winnowings, cutter knockouts, Stem Fibers, Scraps, Short Stems, but also as an attractive and compact solution for a lamina tobacco preparation especially for a complete replacement of a conventional tobacco preparation.
  • the realization is realized that such an extrusion is equivalent to a classical tobacco preparation in lines, with a great advantage is that space and energy can be saved and thus an environmentally friendly operation with increased process flexibility can be provided.
  • the invention can realize an integrated mode of production without the tobacco by-products incurred and guaranteed high material yields.
  • the practiced line specialization (Virginia, Burley, Orient, Rippen) can be maintained in principle.
  • the tobacco laminate material or a tobacco material comprising such a tobacco laminate material can be processed more compactly and faster, and the economic importance of this knowledge according to the invention is considerable, since huge equipment for conditioning, threshing, drying, etc. can be superfluous.
  • the tobacco material supplied as input material to the method according to the invention may comprise a tobacco laminate material and a tobacco rib material, in particular a mixture of a tobacco laminate material and a tobacco rib material, especially substantially all tobacco leaves.
  • a tobacco laminate material and a tobacco rib material in particular a mixture of a tobacco laminate material and a tobacco rib material, especially substantially all tobacco leaves.
  • the process can be fed either raw tobacco directly after harvesting as a whole leaf or after threshing in a green leaf threshing plant (GLT) separately as lamina (strips) and rib.
  • Oriental tobaccos basically find their way as a whole leaf into the tobacco industry.
  • the advantages of the possible delivery of mixtures of lamina (tobacco leaf) and ribs are obvious and relate to the merger of separate process steps. If full leaf is used, there is a high saving potential, because the threshing, ie the separation of rib and leaf, practically unnecessary.
  • the method according to the invention comprises a plurality of extrusion processes, of which at least one material used as input material or a tobacco laminate material, wherein the extruded products produced by the respective extrusion processes together or in mixture form a tobacco preparation product.
  • the advantage of such an arrangement is that the various tobacco materials can also be processed differently in the usual way.
  • extrusion processes take place in parallel (temporal and spatial), and there is the possibility that one, two, three or more extrusion processes for tobacco laminate material are coupled with an extrusion process for tobacco rib material, the tobacco preparation product resulting from the products of these extrusion processes.
  • a disclosed tobacco preparation unit has at least the following components: a metering conveyor and an extruder, which performs a compression of a tobacco material with pressure and temperature increase and a mechanical treatment and sudden relaxation drying of the material at the extruder outlet.
  • the components are formed overall as a modular unit for processing a tobacco material comprising a tobacco laminate material.
  • the tobacco preparation unit on the one hand in its smallest form necessary, but on the other hand with optional additional components a module, so a separate, self-contained unit, which allows flexible use and flexible handling, even spatial displacement.
  • This modular design results in compact and universally applicable, in particular also transportable tobacco preparation units.
  • the tobacco preparation aggregate may be configured to be suitable for performing a tobacco preparation process, as described above in various embodiments.
  • the corresponding unit parts or device parts are provided for this purpose, which are necessary for carrying out the method steps.
  • an arrangement of several tobacco preparation aggregates is to be designed to carry out one of the methods as explained above with regard to “several extrusion processes”. It is possible to provide an aggregate for each extrusion process and to collect the tobacco preparation products of aggregates for further processing in the smoking article manufacturing process, in particular to collect on a conveyor (belt conveyor, gutter conveyor, etc.).
  • a smoking article or device with an aggregate or aggregate arrangement as described above in various embodiments.
  • the aggregate or aggregate arrangement is preceded by a cigarette maker (secondary unit or cigarette manufacturing machine) as a tobacco preparation module (primary module), in particular placed directly on an interface.
  • a tobacco preparation module primary module
  • the modular tobacco preparation can be shipped anywhere because of their small footprint and high throughput and especially because of the wide adjustment options as far as the quality and quantity of the final product (conditioning in the extruder) and used instead of the previously required large-scale tobacco preparation systems. In particular, it may e.g. already shipped to tobacco manufacturing countries, where - for the reasons given above - can also save the Threshing, so that can be produced much faster, cheaper and more space-saving.
  • the infrastructure of the cigarette factory is essentially relieved of capacity in terms of capacities of plants subject to emissions legislation, such as Dedusting plants, vapor treatment plants and wastewater treatment plants.
  • the entire module still has the cooling unit 4, which serves to fix the structure and the extraction of adhering vapor.
  • the feeding of this silo with whole packages can be carried out either with the aid of a slicer or a crusher before entering the mixing container.
  • the thus pre-crushed bulk material can then be homogenized with a silo mixer and further processed.
  • the extruder may include a heatable pressure chamber having a tobacco material inlet on the low pressure side and a tobacco material outlet on the pressure side, and a conveying direction (plug screw for conveying the tobacco material from the inlet to the outlet).
  • the tobacco material outlet has a flow channel cross-section (defined by gap + profiling) for the passage of the tobacco material under relaxation, and the flow channel cross-section preferably has mutually movable gap walls, which may have roughening or profiling.
  • the gap walls can also be moved away from each other and toward each other, biased towards the closed state of the gap and be movable against each other at a fixed or fixed distance (0.01 mm to 2 mm).
  • the roughenings may be grooves or cross-profiles, and the gap may be one Annular gap, cylinder gap or a cone gap, the gap walls in particular against each other continuously or intermittently back and forth.
  • the extruder screw may have measures that reduce the chamber volume to the area of the outlet, in particular degressive screw pitches or progressive extruder shafts, and it is possible to arrange mechanical pre-shredding or pre-shredding means in the pressure chamber. At the pressure chamber inlets for conditioning or casing or steam may be present.
  • FIG. 2 shows variants in tabular form together with the number of extruders required (extruder cells or extruder modules).
  • extruder cells or extruder modules When whole leaf is used without tobacco specialization, minimal extruder is necessary. Then, as in FIG. 1 shown, realized the mixing recipe in a silo of the extrusion module, and it is not differentiated, for example, Virginia, Burley, Orient and ribs process technology.
  • the proportion of the scaffold cellulase corresponds to the natural content in the leaf and is therefore considered to be particularly advantageous in terms of product properties.
  • Embodiments are claimed in which a separate extruder treatment of different tobacco materials or lamina varieties takes place, and in the second line shows the FIG. 1 a variant in which threshed tobacco used so rib and lamina are treated separately. For this minimal two extruders are necessary, and it can be set different cutting widths for rib and lamina or different Casingvariationen be selected.
  • FIG. 3 One of the above versions is in the FIG. 3 1, wherein a rib processing module 10, a Virginia / Burley processing module 20 and an Orient module 30 each perform an extrusion tobacco preparation and then deliver the extruded product respectively via the conveyors 15, 25 and 35 to a common conveyor 50, then the Interface for further cigarette making or cigarette maker forms.
  • the FIG. 4 shows as a whole a cigarette manufacturing device or a "small cigarette factory” with an extrusion module 40 (silo 1, metering screw 2, extruder 3, conveyor 55, dryer 4), which is directly upstream of a cigarette maker 60.
  • the tobacco preparation module 40 thus belongs to one (or a small group of) cigarette machine (s) in quasi a 1: 1 relationship.
  • a conception or the modular tobacco preparation it becomes possible to create independent manufacturing modules for tobacco preparation and cigarette production, and a future factory could consist of integer multiples of such mini-factories, as described in the FIG. 4 are shown. With this concept, an extensive flexibility of the cigarette production or the smoking article production is achieved.
  • a performance adjustment with regard to the tobacco throughput to the cigarette machine requirement can be carried out either with the metering conveyor of the extruder itself (small adjustment range by speed variations) or with the number of extruders per silo (large adjustment range by multiplication of the basic unit).
  • the flavoring can also be included here, for example as proven online flavoring during cigarette production. But you can also advance in a flavor drum together with a mixing of the material before it is passed on to the tobacco silo.
  • An extrusion cell used in the Figures 3 and 4 can need a pitch of 15 x 15m with a capacity of up to 1000kg / h.
  • resource-saving tobacco processing is provided and (energy, vapor attack etc.), without pretreatment of the tobacco material with a nearly 100% raw material yield in a compact extrusion module.
  • various Virginia grades are provided in the form of strips and mixed in a silo 1 with cutting mixing organs for fibrous plant materials without moisturizing according to a recipe.
  • the batch size is set to 4000 kg.
  • the mixing additionally a comminution of the fragile leaf material is consciously accepted.
  • the resulting dust serves to stabilize the process flow. It can be quite advantageous to make tobacco dust or other tobacco small materials from other sources to the recipe component.
  • the batch prepared in this way is fed to the extruder 3 with the aid of a metering screw 2, where it is formed into a fibrous tobacco product as already described.
  • the yield is almost 100%.
  • the sudden expansion creates attractive filling capacities of eg 5.1 ml / g and the product is visually indistinguishable from the classic product.
  • the dust or other small tobacco particles are bound during the compression and extrusion process to the resulting fibrous tobacco material, resulting in the high material yield.
  • the produced cigarettes are of high quality and are easily in the range of the quality of the classical tobacco processing. In addition, they are visually indistinguishable from cigarettes that have been used for classic tobacco processing. The hardness of the cigarettes is even improved in the tobacco preparation according to the invention, namely reduced.
  • the present invention thus makes it possible to produce a perfect smoke product with all the advantages mentioned with regard to the handling of tobacco preparation, its productivity, as well as the savings in parking space, energy and equipment costs.
