Description

Die vorliegende Erfindung betrifft ein Verfahren zur Verarbeitung von Tabakmaterialien mit hohem Anteil an Tabakkleinteilen, insbesondere ein Verfahren zum Verarbeiten von Tabakstaub bei der Tabakvorbereitung für die Herstellung von Rauchartikeln.The present invention relates to a method for processing tobacco materials with a high content of small tobacco particles, in particular a method for processing tobacco dust in tobacco preparation for the production of smoking articles.

Es ist bekannt, Tabakkleinteile, die an verschiedenen Stellen der Tabakverarbeitung (z.B. Transport, Tabakvorbereitung, Rauchartikelherstellung) anfallen können, wieder zu verarbeiten, um sie einer sinnvollen Verwendung zuführen zu können. Beispielsweise können Tabakkleinteile als eines der Eingangsmaterialien für die Tabak-Rekonstitution, z.B. die Tabakfolienherstellung verwendet werden. Bei solchen Prozessen werden meist kontinuierliche Tabakmaterialkörper hergestellt, wie Folien, Platten, Fäden usw.It is known to reprocess tobacco particles, which may be obtained at various points in tobacco processing (e.g., transportation, tobacco preparation, smoking article manufacture), to make them useful. For example, tobacco mince may be included as one of the input materials for tobacco reconstitution, e.g. the tobacco sheet production can be used. In such processes, mostly continuous tobacco material bodies are produced, such as foils, sheets, threads, etc.

Aus der DE 100 65 132 A1 ist ein Verfahren zur Herstellung von Agglomeraten bekannt. Hier wird vorgeschlagen, aus kleinsten Tabakpartikeln, insbesondere aus Tabakstaub, Agglomerate zu machen, also größere Teilchenkomplexe, die nicht in unerwünschter Weise in einer Zigarettenherstellungsmaschine ausgesondert werden. Die feinsten Tabakstaub-Partikel werden mit Bindemitteln und Flüssigkeit gemischt und dann aus einer Verdichtungs- und Erwärmungskammer ausgespritzt, um Agglomerate, also die größeren Einheiten zu bilden.From the DE 100 65 132 A1 For example, a process for producing agglomerates is known. Here it is proposed to make agglomerates of the smallest tobacco particles, in particular of tobacco dust, ie larger particle complexes which are not undesirably separated out in a cigarette manufacturing machine. The finest tobacco dust particles are mixed with binders and liquid and then ejected from a compression and heating chamber to form agglomerates, that is the larger units.

Aus den Druckschriften US-A-3203432 , US-A-3076729 und US-A-4646764 sind Verfahren zur Verarbeitung von Tabakkleinteilen zu einem rekonstituierten Tabakmaterial bekannt.From the pamphlets US-A-3203432 . US-A-3076729 and US-A-4646764 For example, methods of processing tobacco particles into a reconstituted tobacco material are known.

Nachteilig bei dieser Art der Tabakkleinteilverarbeitung, aber auch allgemein bei der Herstellung von Tabakfolie oder kontinuierlichen Körpern aus rekonstituiertem Tabak, ist die Tatsache, dass die Prozesse sehr resourcen-intensiv sind und des Einsatzes von eingebrachten Bindemitteln bedürfen, um Tabakkleinteile sinnvoll verarbeiten zu können.A disadvantage of this type of tobacco small parts processing, but also in general in the production of tobacco foil or continuous bodies of reconstituted Tobacco, is the fact that the processes are very resource-intensive and require the use of incorporated binders to process tobacco small parts meaningful.

Es ist die Aufgabe der vorliegenden Erfindung, ein Verfahren zum Verarbeiten von Tabakkleinteilen zur Verfügung zu stellen, das die vorgenannten Nachteile des Standes der Technik überwindet. Insbesondere soll die Tabakkleinteileverarbeitung einfach und unaufwändig gestaltet werden.It is the object of the present invention to provide a method of processing tobacco particles which overcomes the aforementioned disadvantages of the prior art. In particular, the tobacco small parts processing should be simple and inexpensive.

Diese Aufgabe wird erfindungsgemäß durch ein Verfahren gemäß dem Anspruch 1 gelöst. Die Unteransprüche definieren bevorzugte Ausführungsformen der Erfindung.This object is achieved by a method according to claim 1. The subclaims define preferred embodiments of the invention.

Gemäß der vorliegenden Erfindung wird ein zu verarbeitendes Material, das Tabakkleinteile und Tabakmaterial aufweist, einem erhöhten mechanischen Druck und insbesondere auch erhöhter Temperatur und Feuchtigkeit ausgesetzt, um die Tabakkleinteile bleibend an dem Tabakmaterial anzuhaften. Mit anderen Worten werden die Tabakkleinteile nicht mehr getrennt aussortiert und verarbeitet, sondern mit einem Tabakmaterial zu einer Einheit verbunden, um das Tabakmaterial mit dem daran gebundenen Tabakkleinteilen dann später bei der Herstellung von Rauchartikeln verwenden zu können. Dadurch erspart man sich die aufwändige separate Verarbeitung. Die Tabakkleinteile sind einfach schon an einem Material angehaftet bzw. mit dem Material verbunden, das später ohnehin für die Rauchartikelherstellung verwendet wird. Das zu verarbeitende Material wird am Ende der Verarbeitung durch einen Druckabbau und einer damit einhergehenden Flashverdampfung expandiert.According to the present invention, a material to be processed which comprises tobacco small parts and tobacco material is subjected to an increased mechanical pressure and in particular also elevated temperature and humidity, in order to adhere the tobacco small parts permanently to the tobacco material. In other words, the small pieces of tobacco are no longer sorted out and processed separately, but combined with a tobacco material to form a unit, in order to use the tobacco material with the tobacco small parts attached thereto later in the manufacture of smoking articles. This saves you the time-consuming separate processing. The small tobacco parts are simply already attached to a material or connected to the material, which is later used anyway for smoking article production. The material to be processed is expanded at the end of processing by depressurization and concomitant flash evaporation.

Durch die vorliegende Erfindung wird eine signifikante Verschiebung der Größenverteilung hin zu größeren Teilchen erreicht, besonders im angestrebten Größenbereich von 1-4mm. Dies lässt sich durch Siebanalysen vor und nach der erfindungsgemäßen Behandlung belegen.The present invention achieves a significant shift in size distribution towards larger particles, especially in the desired size range of 1-4mm. This can be demonstrated by sieve analyzes before and after the treatment according to the invention.

Wenn im Rahmen der vorliegenden Beschreibung von Tabakkleinteilen die Rede ist, so sind damit insbesondere Tabakkleinteile gemeint, die eigentlich als nachteilig angesehen werden (auch geschmacklich), ansonsten lediglich abgesaugt oder zur Herstellung von rekonstituiertem Tabak (Tabakfolie) verwendet werden können. Insbesondere sind Tabakkleinteile kleiner als die Schnittbreite von Tabak (z.B. < 1 mm), und noch spezieller sind Tabakkleinteile deutlich kleiner als die Schnittbreite von Tabak (z.B. < 0,5 mm).If in the context of the present description of tobacco small parts is mentioned, so are meant in particular small tobacco pieces, which are actually considered to be disadvantageous (also in terms of taste), otherwise only sucked off or to Production of reconstituted tobacco (tobacco foil) can be used. In particular, tobacco small parts are smaller than the cut width of tobacco (eg, <1 mm), and more specifically, tobacco small parts are significantly smaller than the cut width of tobacco (eg, <0.5 mm).

Wenn hierin der Begriff "Tabakmaterial" verwendet wird, so sind damit grundsätzlich Tabakteile gemeint, die größer oder wesentlich größer sind als Tabakkleinteile, insbesondere solche Tabakteile, die zur Verwendung in Rauchartikeln geeignet sind oder hierzu höchstens noch zerkleinert werden müssen. Das Tabakmaterial kann z.B. ein Tabakrippenmaterial, insbesondere ein Winnowingmaterial, Stem-Fibers oder ein Tabakblattmaterial sowie ein Gemisch aus diesen sein.When the term "tobacco material" is used herein, it basically means tobacco parts which are larger or substantially larger than tobacco small parts, in particular those tobacco parts which are suitable for use in smoking articles or at most have to be comminuted thereto. The tobacco material may e.g. a tobacco rib material, in particular a winnowing material, Stem Fibers or a tobacco leaf material and a mixture thereof.

Das zu verarbeitende Tabakmaterial und die Tabakkleinteile werden im Rahmen der vorliegenden Erfindung auf eine vorbestimmte erhöhte Feuchte gebracht. Ferner wird das zu verarbeitende Material einer Temperaturerhöhung ausgesetzt, die insbesondere aus externer Wärmezufuhr und/oder aus der mechanischen Druckerzeugung resultieren kann.The tobacco material to be processed and the small tobacco particles are brought to a predetermined increased humidity in the present invention. Furthermore, the material to be processed is exposed to a temperature increase, which may result in particular from external heat supply and / or from the mechanical pressure generation.

Die Vorteile des erfindungsgemäßen Verfahrens beruhen ferner insbesondere darauf, dass Tabakmaterialien zusammen mit Tabakkleinteilen unter erhöhter Temperatur und definierter Feuchte einem mechanischen Druck (z.B. in einem Extruder oder einem Förderschnecken-Konditionierer) ausgesetzt werden. Durch den mechanischen Druck werden die Tabakkleinteile an das Tabakmaterial gepresst und mit ihm innig verbunden. Durch die erfindungsgemäßen Verfahrensbedingungen ist die Verbindung des Tabakmaterials mit den Tabakkleinteilen so stark, dass das erfindungsgemäß behandelte Tabakmaterial den normalen Beanspruchungen der Zigarettenherstellung resistent ist, d.h. die Tabakkleinteile bei der Luftförderung während normaler Produktionsbedingungen nicht mehr abfallen. Die mechanische Stabilität ist somit höher als bei gewöhnlichen Tabakfolien-Materialien.The advantages of the method according to the invention are also based in particular on the fact that tobacco materials are exposed to a mechanical pressure (for example in an extruder or a screw conveyor conditioner) together with tobacco particles under elevated temperature and defined humidity. Due to the mechanical pressure, the tobacco particles are pressed against the tobacco material and intimately connected with it. By the process conditions of the invention, the compound of the tobacco material with the tobacco particles is so strong that the tobacco material treated according to the invention is resistant to the normal stresses of cigarette production, i. the tobacco particles do not fall off during the production of air during normal production conditions. The mechanical stability is thus higher than with ordinary tobacco sheet materials.

Gemäß dem Verfahrens kann das zu verarbeitende Material eine seinem Verarbeitungszustand entsprechende Menge an Tabakkleinteilen aufweisen, es kann aber auch mehr als eine solche Menge an Tabakkleinteilen aufweisen, insbesondere eine durch Tabakkleinteilzugabe erhöhte Menge. Dabei würde nicht nur dafür gesorgt, dass die schon angefallenen Tabakkleinteile verarbeitet werden, es könnten auch noch zusätzlich Tabakkleinteile, die an anderen Stellen in der Produktion entstanden sind, verarbeitet werden.According to the method, the material to be processed may have an amount of tobacco small parts corresponding to its processing state, but may also have more than such an amount of tobacco small parts, in particular, an amount increased by tobacco small particle addition. It would not only do so ensure that the small parts of tobacco that have already accumulated are processed, and it would also be possible to process additional tobacco particles that have been produced elsewhere in the production.

Gemäß der Erfindung ist es nicht nötig, zusätzliche bzw. externe Bindemittel zum Binden der Tabakkleinteile an das Tabakmaterial zuzusetzen: weder tabakfremde Bindemittel, noch inhärente, d.h. im Tabak natürlich vorhandene Bindemittel. Entsprechend dem erfindungsgemäßen Verfahren ist es vielmehr möglich, die Tabakkleinteile mechanisch und/oder durch die natürlich im Tabak vorhandenen Mengen an Bindemittel (inhärente Bindemittel) an das Tabakmaterial zu binden. Durch die erfindungsgemäßen Verfahrensbedingungen werden solche inhärenten Bindemittel (Stärke, Harze, Zucker...) aktiviert und halten so die Tabakkleinteile am Tabakmaterial fest. Dies steht im Gegensatz zu solchen Verfahren, wo die Einbringung von Bindemitteln geradezu essentiell ist, nämlich bei der eingangs genannten Folien- oder Agglomeratherstellung.According to the invention, it is not necessary to add additional or external binders for binding the tobacco particles to the tobacco material: neither non-tobacco binders nor inherent, i.e., non-tobacco binders. naturally present in the tobacco binder. According to the method according to the invention, it is rather possible to bind the small tobacco particles mechanically and / or by the amounts of binder (inherent binders) naturally present in the tobacco to the tobacco material. By the process conditions according to the invention such inherent binder (starch, resins, sugar ...) are activated and thus hold the small tobacco particles to the tobacco material. This is in contrast to those methods where the incorporation of binders is almost essential, namely in the aforementioned film or agglomerate production.

Das zu verarbeitende Material kann aber grundsätzlich auch chargenweise verarbeitet werden, insbesondere chargenweise verpresst werden, beispielsweise in einer Kolben-Zylinder-Einheit.The material to be processed can, however, in principle also be processed in batches, in particular, pressed in batches, for example in a piston-cylinder unit.

Das zu verarbeitende Material für das erfindungsgemäße Verfahren kann vorkonditioniert werden, um es zur Verarbeitung geeignet zu machen. Insbesondere das Tabakmaterial wird hierzu auf eine oder mehrere der folgenden Eingangsbedingungen gebracht (Druckangaben immer als Überdruck): Temperatur: 80 - 147°C, bevorzugt 100 - 120°C Eingangsfeuchte: 6 - 13% Ausgangsfeuchte: 18 - 35%, bevorzugt 26 - 30% Druck (Gasüberdruck): 0 - 3 bar, bevorzugt 0 - 1 bar. The material to be processed for the process of the invention may be preconditioned to make it suitable for processing. In particular, the tobacco material is for this purpose brought to one or more of the following input conditions (pressure information always as overpressure): Temperature: 80-147 ° C, preferably 100-120 ° C Input humidity: 6 - 13% Output humidity: 18 - 35%, preferably 26 - 30% Pressure (gas pressure): 0-3 bar, preferably 0-1 bar.

Das erfindungsgemäße Verfahren zur Tabakkleinteileverarbeitung erfolgt bevorzugt mit einem oder mehreren der folgenden Parameter: Temperatur: 80 - 180°C, bevorzugt 140 - 160°C Eingangsfeuchte: 18 - 35%, bevorzugt 26 - 30% Ausgangsfeuchte: 11 - 19%, bevorzugt 15 - 17% mechanischer Druck: 80 - 250 bar, bevorzugt 80 - 110 bar. The method according to the invention for tobacco small particle processing preferably takes place with one or more of the following parameters: Temperature: 80-180 ° C, preferably 140-160 ° C Input humidity: 18 - 35%, preferably 26 - 30% Output humidity: 11 - 19%, preferably 15 - 17% mechanical pressure: 80-250 bar, preferably 80-110 bar.

Die Begriffe Eingangsfeuchte und Ausgangsfeuchte beziehen sich insbesondere auf das Tabakmaterial (Rippen, Winnowings, Stem-Fibers, Blatttabak usw.).The terms input moisture and initial moisture refer in particular to the tobacco material (ribs, winnowings, stem-fibers, leaf tobacco, etc.).

Bei der erfindungsgemäßen Verarbeitung entsteht bevorzugt ein Produkt, welches ein nicht kontinuierliches Tabakmaterial ist, insbesondere ein faseriges und/oder granulares Rauchmaterial bzw. Rauchartikel-Füllmaterial. Mit anderen Worten ergibt das erfindungsgemäße Verfahren ein Produkt, das unmittelbar und konsumfertig in den Rauchartikel eingebracht werden kann. Dies steht insbesondere im Gegensatz zur Erzeugung von Tabakfolie (kontinuierliches Tabakmaterial), deren Herstellung aufwändiger ist und die nach der Herstellung noch geschnitten und getrocknet werden muss. Mit der vorliegenden Erfindung erhält man ein Produkt, das sowohl eine passende Größe als auch eine passende Feuchtigkeit aufweist, um direkt als Füllmaterial für Rauchartikel eingesetzt zu werden.In the processing according to the invention, a product is preferably produced which is a non-continuous tobacco material, in particular a fibrous and / or granular smoking material or smoking article filling material. In other words, the method according to the invention gives a product which can be introduced into the smoking article immediately and ready for consumption. This is in particular in contrast to the production of tobacco foil (continuous tobacco material), the production of which is more complex and which still has to be cut and dried after production. The present invention provides a product having both a suitable size and moisture to be used directly as smoking article filler.

Gemäß einer Ausführungsform der Erfindung können die Tabakkleinteile ein Tabakstaub-Material sein. Das Tabakstaub-Material kann in erheblichen Mengen vorhanden sein, ohne dass dies die Fähigkeit des erfindungsgemäßen Verfahrens, ein hervorragendes Produkt zu erzeugen, beeinträchtigen würde. Der Anteil des Staubes (Tabakstaubes) kann ohne Beeinträchtigungen des Verfahrenserfolges sogar bis an 100% des zu verarbeitenden Materials heranreichen.According to one embodiment of the invention, the tobacco particles may be a tobacco dust material. The tobacco dust material may be present in significant quantities without compromising the ability of the process of the present invention to produce a superior product. The proportion of dust (tobacco dust) can be up to 100% of the processed material without compromising the process success.

Erfindungsgemäß kann das Verfahren so durchgeführt werden, dass das zu verarbeitende Material einen Anteil am Tabakmaterial umfasst, der größer ist als 25%. Ferner kann das zu verarbeitende Material einen Anteil an Tabakkleinteilen umfassen, der kleiner ist als 75%.According to the invention, the method can be carried out so that the material to be processed comprises a proportion of the tobacco material which is greater than 25%. Further, the material to be processed may include a proportion of tobacco particles that is less than 75%.

Im Weiteren soll noch ein positiver Effekt des erfindungsgemäßen Verfahrens beschrieben werden, der die Füllfähigkeit des Endproduktes betrifft. Das zu verarbeitende Material wird - wie oben schon ausgeführt - bei der Verarbeitung einem erhöhten mechanischen Druck ausgesetzt. Dieser erhöhte Druck wird am Ende der Verarbeitung, wenn das Material als Produkt aus der verfahrensgemäßen Verarbeitung austritt, wieder abgebaut. Dies geschieht meist beim Austrag aus der Verarbeitungsvorrichtung, wie sie oben beschrieben wurde (z.B. Extruder, Schneckenförderer, Kolben-Zylinder-Einheit). Durch den Druckabbau beim Austrag aus dieser Vorrichtung kommt es zu einer Flashverdampfung und damit zu einer Expansion des Materials. Abhängig von der Eingangsfüllfähigkeit (gemessen unter ISO-Bedingungen) lassen sich Steigerungen von bis zu 100% erreichen. Zum Beispiel wird ein Eingangsmaterial mit einer Füllfähigkeit von 1,5 ml/g nach der Verarbeitung beim Ausgangsmaterial eine Füllfähigkeit von 3 ml/g aufweisen. Bei einem anderen Material wurden Füllfähigkeitssteigerungen von 1,5 ml/g (Eingangsmaterial) auf 4,5 ml/g (Ausgangsmaterial, Produkt) gemessen. Damit werden erfindungsgemäß Füllfähigkeiten von Materialien mit hohem Kleinteil-Anteil bzw. Staubanteil erreicht, die mit denen von geschnittenem Laminatabak vergleichbar sind.In addition, a positive effect of the method according to the invention is still to be described, which relates to the filling capacity of the end product. The material to be processed is - as already stated above - during processing exposed to increased mechanical pressure. This increased pressure is dissipated at the end of processing, when the material exits as a product from the processing according to the process, again. This is usually done during discharge from the processing apparatus, as described above (eg extruder, screw conveyor, piston-cylinder unit). The pressure reduction during discharge from this device leads to a flash evaporation and thus to an expansion of the material. Depending on the inlet filling capacity (measured under ISO conditions), increases of up to 100% can be achieved. For example, an input material having a filling capacity of 1.5 ml / g after processing on the starting material will have a filling capacity of 3 ml / g. For another material, increases in fillability were measured from 1.5 ml / g (input material) to 4.5 ml / g (starting material, product). In accordance with the invention, filling capacities of materials with a high proportion of small parts or dust content are thus achieved which are comparable to those of cut laminate tobacco.

Die Erfindung betrifft auch einen Rauchartikel, dessen Rauchmaterial oder Teile dessen Rauchmaterials gemäß einem Verfahren hergestellt wurde, wie es oben in unterschiedlichen Ausführungsformen aufgezeigt und erläutert wurde.The invention also relates to a smoking article whose smoking material or parts of its smoking material has been produced according to a method as shown and explained above in different embodiments.
