Description

Verfahren zur Herstellung eines rauchbaren TabakproduktesProcess for producing a smokable tobacco product
Die Erfindung betrifft ein Verfahren zur Herstellung eines rauchbaren Tabakproduktes.The invention relates to a method for producing a smokable tobacco product.
In der DE-33 39 247 Cl ist ein Verfahren zur Herstellung von gekräuselten Faserstücken aus wiederaufbereitetem Tabak offen- bart, bei dem Tabakstaub und/oder Tabakabfälle mit Bindemit¬ teln und ggf. Additiven zu einem plastifizierbaren Gemisch verarbeitet werden. In einem Extruder wird ein zylindrischer Strang aus dem plastifizierten Gemisch zu einem dünnwandigen, sich kontinuierlich erweiternden Hohlkörper umgeformt und in fadenförmige, sich kräuselnde Zwischenprodukte aufgeteilt, die dann in einzelne, gekräuselte Faserstücke zertrennt werden.DE-33 39 247 C1 discloses a process for producing crimped fiber pieces from reprocessed tobacco, in which tobacco dust and / or tobacco waste are processed with binders and, if appropriate, additives to form a plastifiable mixture. In an extruder, a cylindrical strand of the plasticized mixture is formed into a thin-walled, continuously expanding hollow body and divided into thread-like, crimping intermediate products, which are then separated into individual, crimped fiber pieces.
Die DE-38 19 534 Cl offenbart ein Verfahren zur Herstellung von Tabakfolienstücken aus wiederaufbereitetem Tabak. Dabei wird staubförmiger Tabakabfall und/oder Tabakmehl mit Binde¬ mitteln und ggf. Additiven durchgemischt und das so erhaltene Gemisch in einem Extruder plastifziert. Das plastifizierte Gemisch wird über exakt gleichlange Fließwege in eine gerade Zahl von mechanisch/geometrisch identischen zylindrischen Strängen aufgeteilt. Jeweils zwei benachbarte, identischeDE-38 19 534 Cl discloses a method for producing tobacco foil pieces from reprocessed tobacco. Dust-like tobacco waste and / or tobacco flour is mixed with binders and possibly additives and the mixture thus obtained is plastified in an extruder. The plasticized mixture is divided into an even number of mechanically / geometrically identical cylindrical strands via flow paths of exactly the same length. Two adjacent, identical ones
Stränge werden zu einem Folienband zusammengewalzt, das dann zu den Folienstücken zerschnitten wird. Das Plastifizieren des Gemisches im Extruder erfolgt bei Temperaturen von 90 bis 120 °C und Drücken von 50 bis 100 bar. Die zylindrischen Stränge weisen einen Durchmesser von 2 bis 7 mm auf.Strands are rolled together to form a film strip, which is then cut into pieces of film. The mixture is plasticized in the extruder at temperatures of 90 to 120 ° C and pressures of 50 to 100 bar. The cylindrical strands have a diameter of 2 to 7 mm.
In der DE-40 05 656 AI ist ein Verfahren zur Herstellung einer tabakenthaltenden Folie mit erhöhter Füllkraft beschrieben. Hier wird eine Rohmasse mit einem Tabakanteil von ca. 86 bis 98 Gew.% mit einem Anteil von Feuchthaltemitteln von ca. 1 bis ca. 6 Gew.% und einem Bindemittelanteil von ca. 1 bis ca. 8 Gew.% mit Wasseranteil im Verhältnis von 80:20 bis 60:40 vermischt. Die feuchte Rohmasse wird dann in einem Extruder mit einem Temperaturprofil von ca. 30 °C bis ca. 160 °C bei einem Druck von ca. 10 bis ca. 200 bar extrudiert und durch eine mit einem Austrittspalt versehene Düse hindurchgepreßt, wodurch die Tabak-Folie entsteht. Diese Tabak-Folie wird dann von beiden Seiten stark erhitzt, wodurch sich an der Tabak- Folie weitgehend gasundurchlässige Deckschichten bilden. Durch eine weitere starke Wärmezufuhr wird das in der Tabak-Folie befindliche Wasser zwischen den Deckschichten verdampft, wo¬ durch blasenförmige Hohlräume entstehen.DE-40 05 656 AI describes a process for producing a tobacco-containing film with increased filling power. Here a raw mass with a tobacco content of approx. 86 to 98% by weight with a proportion of humectants from approx. 1 to approx. 6% by weight and a binder content of approx. 1 to approx. 8% by weight mixed with water in a ratio of 80:20 to 60:40. The moist raw mass is then extruded in an extruder with a temperature profile of approx. 30 ° C. to approx. 160 ° C. at a pressure of approx. 10 to approx. 200 bar and pressed through a nozzle provided with an exit gap, whereby the tobacco Foil is created. This tobacco film is then strongly heated from both sides, as a result of which largely gas-impermeable cover layers form on the tobacco film. Due to a further strong supply of heat, the water in the tobacco foil is evaporated between the cover layers, whereby bubble-shaped cavities are created.
Der Erfindung liegt die Aufgabe zugrunde, ein neuartiges rauchbares Tabakprodukt bzw. ein Verfahren zu seiner Herstel- lung zu entwickeln.The object of the invention is to develop a novel smokable tobacco product or a method for its production.
Diese Aufgabe wird erfindungsgemäß unter Durchführung folgen¬ der Verfahrensschritte gelöst:This object is achieved according to the invention by performing the following process steps:
a) Herstellung einer Mischmasse aus Tabakteilchen, Stärke bzw. einem stärkehaltigen Produkt als Bindemittel und Additiven;a) production of a mixture of tobacco particles, starch or a starch-containing product as a binder and additives;
b) die Mischmasse wird durch thermische und mechanische Energieeinleitung in einem Extruder verdichtet und plastifiziert;b) the mixed mass is compressed and plasticized by thermal and mechanical introduction of energy in an extruder;
c) dabei wird unter Druck stehender Wasserdampf durch die Mischmasse kanalbildend hindurchgedrückt;c) pressurized water vapor is channeled through the mixed mass;
d) beim Extruderaustritt wird die plastifizierte, durch die Durchströmkanäle porös gestaltete Mischmasse durch Tempe¬ ratur- und Druckabfall expandiert bzw. aufgeschäumt, als kontinuierlicher, poröser, zylindrischer Strang ver- festigt und in gewünschten Längen abgelängt. Die durch Einleitung von Wasserdampf in der Mischmasse erzeug¬ ten Kanäle bleiben im extrudierten Strang in Form longitudina- ler und radialer Kanäle erhalten. Beim Abrauchen dieses Stran¬ ges spielt sich der gleiche Vorgang ab wie bei einem herkömm- lieh hergestellten Tabakstrang mit dem Unterschied, daß died) at the extruder outlet, the plasticized mixed mass, which is porous through the through-flow channels, is expanded or foamed by a drop in temperature and pressure, solidified as a continuous, porous, cylindrical strand and cut to length in the desired lengths. The channels created by introducing water vapor into the mixed mass remain in the extruded strand in the form of longitudinal and radial channels. When this strand is smoked, the same process takes place as with a conventionally produced tobacco strand, with the difference that the
Verbrennungsluft durch die erstarrten Luftkanäle anstatt durch Zwischenräume im Schnitttabak gesaugt wird. Jedoch ist auch der erfindungsgemäß hergestellte Strang dergestalt luftdurch¬ lässig, daß die Verbrennungsluft beim Abrauchen gleichmäßig durch den Strangquerschnitt und die Stranglänge gesaugt wird, wobei der dabei durch den Strang gegebene Zugwiderstand einen oberen Wert nicht überschreitet.Combustion air is sucked through the solidified air channels instead of through gaps in the cut tobacco. However, the strand produced according to the invention is also air-permeable in such a way that the combustion air is sucked evenly through the strand cross-section and the strand length when being smoked, the tensile resistance given by the strand not exceeding an upper value.
Als Bindemittel kann native und/oder modifizierte Stärke ver- wendet werden, wobei der Anteil der Bindemittel vorteilhaft bei etwa 15 Gew.% liegt.Native and / or modified starch can be used as the binder, the proportion of the binder advantageously being about 15% by weight.
Als Additive können Feuchthaltemittel zugemischt werden, wie z. B. Glyzerin, Melassen und/oder andere hygroskopische Stoffe.As additives, humectants can be added, such as. B. glycerin, molasses and / or other hygroscopic substances.
Ferner können als Additive Brandverbesserer vorgesehen werden z. B. organische Säuren zur Erzeugung eines Weißbrandes der Asche und/oder Karbonate oder Netzmittel zur Verbesserung der Glimmfähigkeit.Furthermore, fire improvers can be provided as additives, for. B. organic acids to produce a white fire of the ashes and / or carbonates or wetting agents to improve the smoldering ability.
Schließlich können als Additive auch Aromen und/oder Würzen vorgesehen werden wie z. B. Aromapräkursoren, Extrakte und Wasserdampfdestillate aus gereiften Blättern anderer Pflanzen als Tabakpflanzen.Finally, flavors and / or flavorings can also be provided as additives, such as. B. aroma precursors, extracts and steam distillates from ripened leaves of plants other than tobacco plants.
Vorteilhafte Additive sind auch filmbildende Zusatzstoffe auf biologischer Basis. Zur Beschleunigung der Verarbeitung im Extruder kann der Mischmasse Polyvinylalkohol (PVA) oder Poly- vinylacetat (PVAC) zugesetzt werden. Hierdurch ergibt sich eine bessere Aufschäumung mit guter Elastizität/Flexibilität der Mischmasse. Hinsichtlich der bevorzugten Anwendungsarten des PVA kann auf die Beschreibung in der DE-40 08 862 Cl ver¬ wiesen werden.Biological film-forming additives are also advantageous additives. To accelerate processing in the extruder, polyvinyl alcohol (PVA) or polyvinyl acetate (PVAC) can be added to the mixture. This results in better foaming with good elasticity / flexibility of the mixed mass. Regarding the preferred types of application of the PVA can be referred to the description in DE-40 08 862 Cl.
Erfindungsgemäß können auch Zusatzstoffe aus gengestützter Produktion Verwendung finden.According to the invention, additives from gene-assisted production can also be used.
Zur Erzeugung der für das Abrauchen notwendigen Kanäle wird ein Wasserdampfdruck von 50 - 120 bar, vorzugsweise etwa 80 bar gewählt.A water vapor pressure of 50-120 bar, preferably approximately 80 bar, is selected to generate the channels required for smoking.
Die für die Miεchmasse verwendeten Tabakteilchen lassen sich durch Zerkleinerung ausgereifter Tabakblätter herstellen, kön¬ nen aber auch Abfälle aus der herkömmlichen Tabakverarbeitung sein. Dabei werden Tabakteilchen vorzugsweise in einer Sieb- große von etwa 3 bis 5 mm verwendet.The tobacco particles used for the mix can be produced by crushing mature tobacco leaves, but can also be waste from conventional tobacco processing. Tobacco particles are preferably used in a sieve size of about 3 to 5 mm.
Der handelsüblich verpackte ausgereifte Tabak hat eine lang¬ wierige biochemische Entwicklung durchgemacht: Schon vor der Blatternte tritt noch auf dem Acker ein Abbau im Tabak ein, der nach der Ernte mit zunehmender Vergilbung, Trocknung und Fermentation fortgesetzt wird. Der Chemismus der Reifung ist wesentlich von einem möglichst langsamen Wasserverlust abhän¬ gig. Die anfänglich im vitalen Zustand relativ hohen Konzen¬ trationen von Stärke und Eiweiß werden bei noch hohem Wasser- gehalt bis etwa 80 Gew.% hydrolisiert und in lösliche Zucker und StickstoffVerbindungen überführt. Bei einem Wassergehalt < 80 % werden die diese Vorgänge auslösenden Fermente inaktiv; es tritt der sogenannte Blatt-Tod ein. Um die Reifung voll zur Wirkung kommen zu lassen, ist es daher erwünscht, die Trock- nung innerhalb von 100 Stunden auszuführen; während dieser Zeit wird die Temperatur von 32 °C auf 80 °C herauf und die relative Luftfeuchtigkeit von 80 % auf 10 % bei zunehmender Erhöhung der Belüftung heruntergefahren.The mature tobacco, which is packaged in a commercially available manner, has undergone a lengthy biochemical development: Even before the leaves are harvested, tobacco degradation occurs in the field, which continues after harvesting with increasing yellowing, drying and fermentation. The ripening chemistry is essentially dependent on the slowest possible water loss. The starch and protein concentrations, which were initially relatively high in the vital state, are hydrolyzed with still high water content up to about 80% by weight and converted into soluble sugars and nitrogen compounds. If the water content is <80%, the enzymes that trigger these processes become inactive; the so-called leaf death occurs. In order for the ripening to take full effect, it is therefore desirable to carry out the drying within 100 hours; During this time, the temperature is increased from 32 ° C to 80 ° C and the relative humidity is reduced from 80% to 10% as the ventilation increases.
Da derartige Bedingungen bei Belassung der Tabakblätter in natürlichem Klima nur sehr selten verläßlich erreichbar sind, ist eine derartige Behandlung in der Regel nur in gesteuerter Umgebung möglich. Es ist ferner plausibel, daß die Wirksamkeit der künstlich angestrebten optimalen Reifungsbedingungen um so größer wird, je kleiner und feindisperser Oberfläche und Volu¬ men der zu behandelnden Blattsubstanz sind.Since such conditions can only very rarely be reliably achieved when the tobacco leaves are left in a natural climate, such treatment is generally only controlled Environment possible. It is also plausible that the effectiveness of the artificially desired optimal ripening conditions increases the smaller and finely dispersed the surface and volume of the leaf substance to be treated.
Ausgehend von diesen Erkenntnissen wird nun erfindungsgemäß vorgeschlagen, zur Herstellung der Tabakteilchen für die vor¬ stehend beschriebene Mischmasse noch nicht ausgereifte Tabak¬ blätter zu verwenden und zu zerkleinern, um dann die Reifung des Tabaks im extrudierten Strang, also im fast fertigen Pro¬ dukt durchzuführen. Hierfür werden die erfindungsgemäß herge¬ stellten Strangabschnitte in belüfteter, klimagesteuerter Um¬ gebung konditioniert, also in luftdurchlässigen Behältern in klimagesteuerten Kammern aufbewahrt. Dabei erfolgt die Kondi- tionierung bis zu einer Endfeuchte im Strang von etwa 10 bis 13 % bei etwa 50 °C. In diesem Zustand findet dann die Über¬ führung in die letzte Fertigungsstufe statt:On the basis of these findings, it is now proposed according to the invention to use tobacco leaves which have not yet matured in the manufacture of the tobacco particles for the mixed composition described above, and to shred them, in order then to carry out the maturation of the tobacco in the extruded strand, that is to say in the almost finished product . For this purpose, the strand sections produced according to the invention are conditioned in a ventilated, climate-controlled environment, that is to say they are kept in air-permeable containers in climate-controlled chambers. The conditioning takes place up to a final moisture content in the strand of about 10 to 13% at about 50 ° C. The transfer to the last production stage then takes place in this state:
Das sogenannte "aging" besteht in einer Lagerung der Strang- abschnitte über einen Zeitraum von etwa 0,5 bis 2 Jahren bei 20 °C und 60 bis 75 %iger Luftfeuchtigkeit. Danach findet die Endverpackung statt.The so-called "aging" consists of storing the strand sections over a period of about 0.5 to 2 years at 20 ° C. and 60 to 75% atmospheric humidity. The final packaging then takes place.
Ein Vorteil bei diesem erfindungsgemäßen Verfahren liegt ein- mal darin, daß die Wasserdampfbehandlung die Tabakreifung we¬ sentlich beeinflussen kann. Zum anderen aber kann der noch relativ hohe native Stärkegehalt im Aufbereitungsverfahren ausgenutzt werden. Schließlich eröffnet dieses Verfahren die Möglichkeit, ganze Pflanzen und nicht nur deren Blätter bei einem nur mittleren Reifegrad zu ernten, zu zerkleinern und dann dem erfindungsgemäßen Prozeß zu unterwerfen. Dabei kann auch der relativ höhere Wasservorrat der Ganzpflanze in Form der Quellungswässer vorteilhaft genutzt werden.One advantage of this method according to the invention is that the steam treatment can significantly influence the ripening of tobacco. On the other hand, the still relatively high native starch content can be exploited in the preparation process. Finally, this method opens up the possibility of harvesting whole plants and not just their leaves with only an average degree of ripeness, and then subjecting them to the process according to the invention. The relatively higher water supply of the whole plant in the form of the spring water can also be used to advantage.
Mit dem neuen Verfahren läßt sich die Herstellung völlig neu¬ artiger Zigaretten praktisch vollständig mechanisieren von der Tabakpflanze bis zum Endprodukt. With the new process, the production of completely new types of cigarettes can be mechanized almost completely from the tobacco plant to the end product.
