Description
Die vorliegende Erfindung betrifft ein Verfahren zur Verbesserung der Füllfähigkeit von Tabak gemäß Oberbegriff Hauptanspruch.The present invention relates to a method for Improvement of the filling capacity of tobacco according to the preamble Main claim.
Zur Verbesserung der Füllfähigkeit von Tabak haben sich die INCOM-Blähverfahren nach beispielsweise DE 31 19 330 A1, DE 34 14 625 C2 und DE 39 35 774 C2 durchgesetzt. Bei diesen Verfahren wird Tabak, etwa in Form geschnittener Tabakblätter oder -rippen, mit einer Ausgangsfeuchte bis zu etwa 30 Gew.-% mit einem aus Stickstoff und/oder Argon bestehenden Behandlungsgas bei Drücken von 50 bis 1.000 bar einer kontinuierlichen oder stufenartigen Kompression ausgesetzt, worauf sich eine kontinuierliche oder stufenartige Dekompression anschließt. Die Kompressions- und Dekompressionsschritte erfolgen entweder in einem Autoklaven oder bei kaskadenartiger Schaltung in mehreren Autoklaven. Anschließend wird das ausgetragene Tabakmaterial einer thermischen Nachbehandlung unterworfen, bei welcher sich der Tabak aufbläht und somit die Füllfähigkeit des Tabaks erhöht.To improve the filling capacity of tobacco, the INCOM blowing method according to, for example, DE 31 19 330 A1, DE 34 14 625 C2 and DE 39 35 774 C2 enforced. In these Process is tobacco, roughly in the form of cut tobacco leaves or ribs, having an initial moisture content of up to about 30% by weight with one consisting of nitrogen and / or argon Treatment gas at pressures of 50 to 1,000 bar one exposed to continuous or step-like compression, what is a continuous or step-like Decompression connects. The compression and Decompression steps are carried out either in an autoclave or in a cascaded circuit in several autoclaves. Subsequently, the discharged tobacco material is a subjected to thermal aftertreatment, in which the It inflates tobacco and thus increases the filling capacity of the tobacco.
Diese INCOM-Verfahren haben sich gegenüber den Druckbehandlungsverfahren von Tabak mit Kohlendioxid, Ammoniak oder flüchtigen organischen Verbindungen als vorteilhaft erwiesen, da bei letzteren eine unerwünschte Herauslösung von Aromastoffen oder Nikotin aus dem Tabakmaterial in Kauf genommen werden muss bzw. Reste von Gasen im Tabakmaterial geschmacklich stören oder weil letztlich bei Verwendung von Kohlendioxid die Entfernung von dem sich bei Dekompression bildenden Trockeneis zu energieaufwendig ist.These INCOM procedures have turned against the Pressure treatment process of tobacco with carbon dioxide, Ammonia or volatile organic compounds as proved advantageous, since in the latter an undesirable Dissolution of flavors or nicotine from the Tobacco material must be taken into account or remains of Gas in the tobacco material disturb the taste or because ultimately, when using carbon dioxide the removal of to the forming during decompression dry ice is energy consuming.
Hinsichtlich der erwähnten INCOM-Verfahren beschreibt die DE 31 19 330 A1 ein derartiges Blähverfahren mit im Autoklaven vorherrschenden Arbeitstemperaturen von 0 bis 50°C, wobei man zur Erhöhung der Füllfähigkeit oder des Blähgrades den Einsatz eines Tabakmaterials mit einer Feuchte von bis zu 15 Gew.-% und eine Nachbehandlung mit Wasserdampf vorsieht. Ferner offenbaren die DE 34 14 625 C2 und DE 39 35 774 C2 Kaskadenverfahren, bei denen durch Kühlung des Behandlungsgases vor der Beaufschlagung des Reaktors, durch Kühlung des Autoklaven oder durch Einsatz eines unterkühlten und verflüssigten Behandlungsgases eine niedrige Arbeitstemperatur bei der Imprägnierung des Tabaks bewirkt wird.With regard to the mentioned INCOM method describes the DE 31 19 330 A1 such a blowing method with im Autoclave prevailing operating temperatures from 0 to 50 ° C, where to increase the filling capacity or the Blähgrades the use of a tobacco material with a moisture of up to 15% by weight and aftertreatment with water vapor provides. Furthermore, DE 34 14 625 C2 and DE 39 35 774 C2 cascade method, in which by cooling the treatment gas before charging the reactor, by cooling the autoclave or by using a supercooled and liquefied treatment gas a low Working temperature in the impregnation of the tobacco causes becomes.
Bei diesen bekannten Verfahren erfolgt die thermische Nachbehandlung mit Wasserdampf einer Dichte von 0,5 bis 10 kg/m3, vorzugsweise Sattdampf, oder mit Heißluft von bis zu 440 °C.In these known methods, the thermal aftertreatment with steam at a density of 0.5 to 10 kg / m 3 , preferably saturated steam, or with hot air of up to 440 ° C.
Es ist zwar aus der EP 484 899 B1 ein Verfahren zur Behandlung des Tabaks mit Kohlendioxid bei Drücken von etwa 30 bar bekannt, bei dem die thermische Nachbehandlung durch Einspeisen des Tabaks in Hochtemperaturdampf oder in ein 50 bis 95 Vol.-% Wasserdampf enthaltendes Gas bei Erwärmung des Tabaks im strömenden Medium bei 200 bis 350 °C erfolgt, wobei Wasser oder Dampf mit einer niedrigeren Temperatur stromabwärts der Tabakeinspeisungsstelle zur Temperaturabsenkung des strömenden Mediums eingesetzt wird. Der hierbei mittels wärmeübertragender strömender Medien auf eine Feuchte von etwa 2 bis 3 Gew.-% abgetrocknete Tabak wird dann wieder auf seine Normalfeuchte eingestellt. Da bei der Druckbehandlung des Tabaks mit Kohlendioxid nach der Dekompression die Bildung von Trockeneis auftritt, muss zur thermischen Nachbehandlung des Tabaks die Erwärmung des Tabaks trotz der hohen Verdampfungsenthalpie des Trockeneises rasch erfolgen, was zu einer starken thermischen und/oder mechanischen Belastung des Tabaks führt. Although it is from EP 484 899 B1 a method for Treatment of the tobacco with carbon dioxide at pressures of about 30 bar known, in which the thermal treatment by Feeding the tobacco into high temperature steam or into a 50 to 95 vol .-% water vapor-containing gas with heating of the Tobacco is carried out in the flowing medium at 200 to 350 ° C, wherein Water or steam at a lower temperature downstream of the tobacco feed station to Lowering the temperature of the flowing medium is used. The case by means of heat transferring flowing media a moisture of about 2 to 3 wt .-% dried tobacco is then adjusted to its normal humidity again. Since at the Pressure treatment of the tobacco with carbon dioxide after the Decompression the formation of dry ice occurs, must thermal aftertreatment of tobacco heating of the Tobacco despite the high evaporation enthalpy of dry ice quickly, resulting in a strong thermal and / or mechanical stress on the tobacco.
Bei dem der vorliegenden Erfindung zu Grunde liegenden INCOM-Verfahren benötigen die mit Stickstoff und/oder Argon behandelten Tabake einen sehr viel geringeren Energiebedarf zur Desorption der aufgenommenen Gase und der damit verbundenen Expansion des Tabaks als die mit CO2 behandelten Tabake, so daß beim INCOM-Verfahren im Gegensatz zum CO2-Verfahren keine geschmacklichen Beeinträchtigungen auftreten. Ferner wird bei der thermischen Nachbehandlung von mit Stickstoff und/oder Argon behandeltem Tabak durch die Kondensation von Wasserdampf auf dem kalten Tabak Wärme übertragen und im weiteren Verlauf der thermischen Nachbehandlung durch Abtrocknung der gewünschte Feuchtegehalt des expandierten Tabaks erzielt.In the INCOM process underlying the present invention, the nitrogen and / or argon-treated tobaccos require much less energy to desorb the ingested gases and the associated expansion of the tobacco than the CO 2 -treated tobaccos, so that INCOM Process in contrast to the CO 2 process no taste impairments occur. Furthermore, in the thermal aftertreatment of tobacco treated with nitrogen and / or argon, heat is transferred to the cold tobacco by the condensation of water vapor, and the desired moisture content of the expanded tobacco is achieved during the further course of the thermal aftertreatment by drying.
Gleichwohl besteht auch beim INCOM-Verfahren die Gefahr des Überfeuchtens oder Überwärmen des Tabaks mit der Folge von Füllfähigkeitsverlusten durch Kollabieren der expandierten Zellstruktur.Nevertheless, there is also a risk of the INCOM procedure Overwetting or overheating the tobacco with the result of Füllfähsverlusten by collapsing the expanded Cell structure.
Der Erfindung liegt die Aufgabe zu Grunde, bei dem INCOM-Verfahren die thermische Nachbehandlung des mit Stickstoff und/oder Argon behandelten Tabaks so durchzuführen, dass eine gleichmäßige Produktqualität mit optimaler Füllfähigkeit erreicht wird.The invention is based on the object, in the INCOM method the thermal aftertreatment with nitrogen and / or argon treated tobacco so that a uniform product quality with optimum filling capacity is reached.
Zur Lösung dieser Aufgabe wird daher ein Verfahren gemäß Oberbegriff Hauptanspruch vorgeschlagen, welches dadurch gekennzeichnet ist, dass die thermische Nachbehandlung mit einem strömenden wärmeübertragenden Medium aus einer Mischung von Permanentgasen und überhitztem Wasserdampf durchgeführt wird, wobei der Anteil von Permanentgas konstant auf einem Wert im Bereich von 10 bis 60 Vol.-% gehalten wird.To solve this problem, therefore, a method according to Preamble main claim proposed, which thereby is characterized in that the thermal aftertreatment with a flowing heat transfer medium from a mixture performed by permanent gases and superheated steam is, the proportion of permanent gas constant on a Value is kept in the range of 10 to 60 vol .-%.
Unter Permanentgas wird in diesem Zusammenhang jedes Gas verstanden, welches zusammen mit Wasserdampf beim Trocknen eingesetzt werden kann, wie Luft, gegebenfalls vermengt mit Stickstoff und/oder Argon oder anderen Inertgasen.Permanent gas in this context is any gas understood, which together with steam during drying can be used, such as air, if necessary mixed with Nitrogen and / or argon or other inert gases.
Überraschenderweise hat sich gezeigt, dass der Anteil an Permanentgas im Gemisch mit überhitztem Wasserdampf ein wesentlicher Parameter ist, um unter den gegebenen Verfahrensbedingungen und insbesondere in einem Stromtrocknungsverfahren optimale Füllfähigkeitswerte zu erzielen.Surprisingly, it has been shown that the proportion of Permanent gas mixed with superheated steam essential parameter is given to the given Process conditions and in particular in one Electricity drying method optimum Füllfähigkeitswerte too achieve.
Vorzugsweise wird als Permanentgas im wesentlichen Luft verwendet, wobei die Regelung des Luftanteils indirekt mittels einer Messung des Sauerstoffgehaltes erfolgt. Der Luftanteil des strömenden wärmeübertragenden Mediums beträgt vorzugsweise 20 bis 50 Vol.-% und insbesondere 25 bis 40 Vol.-%.Preferably, the permanent gas is substantially air used, with the regulation of the proportion of air indirectly by means of a measurement of the oxygen content. Of the Air content of the flowing heat transfer medium is preferably 20 to 50% by volume and in particular 25 to 40% by volume.
Vorzugsweise soll die Temperatur des wärmeübertragenden
Mediums bei 120 bis 300 °C liegen, und die Tabakfeuchte des
druckbehandelten Tabaks soll vor der thermischen
Nachbehandlung 8 bis 25 Gew.-% betragen. Ferner ist es
zweckmäßig, wenn die Tabakfeuchte nach der thermischen
Nachbehandlung 8 bis 15 Gew.-% beträgt.Preferably, the temperature of the heat-transferring
Medium at 120 to 300 ° C, and the tobacco moisture of the
pressure-treated tobacco should be before the thermal
After
Bei einer besonders bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens wird so vorgegangen, dass bei der thermischen Nachbehandlung die Zuführung von Heißdampf in einem geschlossenen System nach dem bekannten Prinzip der Stromtrocknung erfolgt, bei welchem das Permanentgas stromabwärts von der Heißdampfeinspeisung im Bereich der Ausschleusung des wärmebehandelten Tabaks eingespeist wird und nach Abkühlung des expandierten Tabaks und Austragung desselben anschließend unter Regelung der Konstanz des Anteils an Permantgas mit weiterem Wasserdampf im geschlossenen Kreislauf zirkuliert wird. Hierbei wird insbesondere eine schnelle Senkung der Tabaktemperatur und damit die Fixierung der Füllfähigkeit erreicht.In a particularly preferred embodiment of the The method according to the invention is carried out in such a way that the thermal aftertreatment, the supply of superheated steam in a closed system according to the known principle of Electric drying takes place, in which the permanent gas downstream of the hot steam feed in the area of Outfeed of the heat-treated tobacco is fed and after cooling of the expanded tobacco and discharge the same subsequently under regulation of the constancy of the Proportion of permant gas with further water vapor in the closed circuit is circulated. This is in particular a rapid reduction of the tobacco temperature and so that the fixation reaches the filling capacity.
Im folgenden wird unter Bezugnahme auf die in Fig. 1 wiedergegebene schematische Darstellung eine bevorzugte Verfahrensführung mittels eines üblichen Stromtrockners erläutert, wobei Luft als Permanentgas verwendet und dessen Anteil indirekt über eine Sauerstoffmessung bestimmt wurde.In the following, with reference to the in Fig. 1 reproduced schematic representation of a preferred Process control by means of a conventional power dryer explained, with air used as a permanent gas and its Proportion was determined indirectly via an oxygen measurement.

The supply of superheated steam takes place via a steam valve (4). With a probe (5) was the Measurement of the oxygen content in the heat transfer medium carried out. By controlling the steam valve (4) and the Breathable flap (3) can the desired oxygen content and thus a constant ratio of permanent gas to superheated steam.
Anhand des folgenden Ausführungsbeispiels wird die Abhängigkeit der Füllfähigkeit vom Permanentgasanteil im wärmeübertragenden Medium demonstriert. Der im jeweiligen Einzelfall zur Erzielung einer optimalen Füllfähigkeit notwendige Permanentgasanteil hängt ab von Art und der Feuchte des eingesetzten Tabakmaterials sowie von den apparativen Randbedingungen. With reference to the following embodiment, the Dependence of the filling capacity on the percentage of permanent gas in the heat transfer medium demonstrated.
