Tabak wird nach der Ernte auf eine relativ geringe Restfeuchte von in etwa 9% bis 12% getrocknet und zum Versand gewöhnlich in Ballen oder Pakete gepresst. Wenn dieser relativ trockene Tabak zu Rauchprodukten weiterverarbeitet werden soll, so ist es erforderlich, die in den gepressten Ballen vorhandenen einzelnen Blätter oder Blattstücke bzw. Rippen oder Rippenstücke wieder voneinander zu lösen und zu vereinzeln. Dieser als Lösen des Tabakguts bekannte Prozess ist ein Teilprozess der Tabakaufbereitung.Tobacco is dried after harvest to a relatively low residual moisture content of about 9% to 12% and is usually pressed into bales or packages for shipping. When this relatively dry tobacco is to be further processed into smoke products, it is necessary to separate and separate the individual leaves or leaf pieces or ribs or rib pieces present in the pressed bales from one another. This known as dissolving the tobacco product process is a sub-process of tobacco processing.
Die getrockneten und in Tabakballen gepressten Tabakblätter haften stark aneinander und sind aufgrund ihrer geringen Feuchte außerdem brüchig und sehr empfindlich gegen mechanische Einwirkungen. Das Lösen des Tabakguts muss also schonend geschehen. Bei den angewandten Verfahren zum Lösen von Tabakgut werden die Tabakballen zunächst mechanisch in kleinere Portionen vorgeschnitten. Der Tabakballen wird beispielsweise mit einem sog. "Slicer", vorzugsweise senkrecht zur Blattgutlage, in Tabakscheiben vorgeschnitten oder mittels Gabeln portioniert.The dried tobacco leaves pressed into tobacco bales adhere strongly to each other and are also fragile due to their low moisture content and very sensitive to mechanical effects. The release of the tobacco must therefore be gentle. In the methods used for releasing tobacco, the tobacco bales are first mechanically precut into smaller portions. The tobacco bale is precut for example with a so-called "slicer", preferably perpendicular to the sheet material, cut into tobacco slices or portioned by means of forks.

In order nevertheless to compensate for a drift in the process air temperature, a heat exchanger is integrated in the return line. However, this is only possible in a very narrow regulatory area.
Ausgehend von diesem Stand der Technik besteht die Aufgabe der Erfindung darin, eine Einrichtung sowie ein Verfahren zum Lösen von Tabakgut bereitzustellen, wobei eine verbesserte Regelung der Prozessparameter, insbesondere der Prozesstemperatur, möglich sein soll.Based on this prior art, the object of the invention is to provide a device and a method for releasing tobacco, wherein an improved control of the process parameters, in particular the process temperature should be possible.
Gelöst wird diese Aufgabe durch eine Einrichtung zum Lösen von Tabakgut, umfassend eine Prozesstrommel mit einer an einer Einbringseite vorgesehenen Einbringöffnung, durch die Tabakgut in einen Innenraum der Prozesstrommel einbringbar ist oder eingebracht wird, und mit einer an einer Ausbringseite vorgesehenen Ausbringöffnung, durch die gelöstes Tabakgut mit einer bestimmten Temperatur aus dem Innenraum der Prozesstrommel ausbringbar ist oder ausgebracht wird, eine Prozessluftzufuhreinheit zum Einleiten von Prozessluft in den Innenraum der Prozesstrommel, Mittel zum Einbringen von Dampf und/oder Wasser in die Prozessluft und/oder in den Innenraum der Prozesstrommel, eine Frischluftzufuhreinheit zum Zuführen von Frischluft zu der Prozessluft, wobei mittels der Prozessluft das im Innenraum der Prozesstrommel vorhandene Tabakgut behandelbar ist, die Einrichtung ist dadurch weitergebildet, dass eine Regelungseinheit und ein damit verbundener Temperatursensor zur Erfassung der Temperatur des gelösten Tabakguts vorgesehen ist und die Frischluftzufuhreinheit einen ersten von der Regelungseinheit regelbaren Volumenstromregler zur Regelung eines der Prozessluft zugeführten Volumenstroms an Frischluft umfasst, wobei die Regelungseinheit dazu eingerichtet ist, den der Prozessluft zugeführten Volumenstrom an Frischluft so zu regeln, dass in Abhängigkeit von der erfassten Temperatur des gelösten Tabakguts der von dem ersten Volumenstromregler eingestellte Volumenstrom an Frischluft beeinflussbar ist.This object is achieved by a device for releasing tobacco, comprising a process drum with a supply opening provided on a Einbringseite through which tobacco material is introduced or introduced into an interior of the process drum, and provided with a discharge side discharge opening, through the dissolved tobacco a process air supply unit for introducing process air into the interior of the process drum, means for introducing steam and / or water into the process air and / or into the interior of the process drum, a Frischluftzufuhreinheit for supplying fresh air to the process air, wherein the tobacco material present in the interior of the process drum can be treated by means of the process air, the device is further developed by a control unit and a temperature sensor connected thereto is provided for detecting the temperature of the dissolved tobacco product and the fresh air supply unit comprises a first controllable by the control unit volumetric flow controller for controlling a process air supplied volume flow of fresh air, wherein the control unit is adapted to control the process air supplied volume flow of fresh air so that in Depending on the detected temperature of the dissolved tobacco product of the first volume flow controller set volume flow of fresh air can be influenced.
Die Erfindung beruht auf dem Gedanken, dass in einer Einrichtung zum Lösen von Tabakgut die Temperatur und auch die Feuchte der Prozessluft, mittels eines der Prozessluft zugeführten Frischluftstroms regelbar sind. Der Volumenstrom an Frischluft, der der Prozessluft zur Behandlung des Tabakguts beigemischt wird, ist in Abhängigkeit von der Temperatur des gelösten Tabakguts, welches die Prozesstrommel verlässt, geregelt. Bei der Tabakaufbereitung in der erfindungsgemäßen Einrichtung erfolgt eine direkte Erfassung der Temperatur des gelösten Tabakguts. So wird eine gleichbleibend hohe Qualität des gelösten Tabakguts sichergestellt und dessen Temperatur wird während des Lösevorgangs sehr konstant auf einem vorgegebenen Temperatursollwert gehalten. Dies gilt insbesondere, wenn der Prozess mit einem konstanten Verhältnis von Tabak zu Dampf gefahren wird.The invention is based on the idea that in a device for releasing tobacco material, the temperature and also the humidity of the process air, by means of a fresh air flow supplied to the process air can be regulated. The volume flow of fresh air, which is added to the process air for the treatment of the tobacco, is regulated in dependence on the temperature of the dissolved tobacco product leaving the process drum. In tobacco processing in the device according to the invention, a direct detection of the temperature of the dissolved tobacco product takes place. Thus, a consistently high quality of the dissolved tobacco product is ensured and its temperature is kept very constant during the dissolution process at a predetermined temperature setpoint. This is especially true when the process is run at a constant ratio of tobacco to steam.
Mit anderen Worten bedient sich die erfindungsgemäße Einrichtung der Temperatur des Tabakguts als Regelgröße, wobei der Volumenstrom der Frischluft die Stellgröße des Prozesses ist.In other words, the device according to the invention uses the temperature of the tobacco product as a controlled variable, wherein the volume flow of the fresh air is the manipulated variable of the process.
Bei der vorliegenden Erfindung besteht der Regelmechanismus darin, die Wasserbeladung der Prozessluft und damit ihre relative Feuchte über das Mischungsverhältnis der Prozessluft mit Frischluft zu verändern. Durch die Beimischung von Frischluft zu der Prozessluft wird die relative Feuchte in der Prozessluft reduziert. Durch die Reduzierung der relativen Feuchte wird der Vorgang begünstigt, dass Wasser der feuchten Oberfläche des Tabakguts in die Prozessluft verdampft, bis sich ein Gleichgewicht zwischen der Wasserabgabe des feuchten Tabakguts mit dem Wasseraufnahmevermögen der Prozessluft einstellt. Für den Verdampfungsvorgang des Wassers in die Prozessluft ist Wärme erforderlich, die dem Tabakgut entzogen wird. Durch den Entzug von Wärme für den Verdampfungsvorgang sinkt die Tabaktemperatur in dem Tabakgut. Gemäß dem oben gesagten kann durch die Zugabe von Frischluft also eine Kühlung des Tabakguts in einfacher Weise erreicht werdenIn the present invention, the control mechanism is the water loading of the process air and thus their relative humidity on the mixing ratio of the process air with fresh air to change. The addition of fresh air to the process air reduces the relative humidity in the process air. By reducing the relative humidity, the process is favored that water evaporates the wet surface of the tobacco into the process air until a balance between the discharge of water of the wet tobacco with the water absorption capacity of the process air. For the evaporation process of the water in the process air heat is required, which is withdrawn from the tobacco. Due to the removal of heat for the evaporation process, the tobacco temperature drops in the tobacco. According to the above can therefore be achieved by the addition of fresh air cooling of the tobacco in a simple manner
Eine Regelung der Feuchte und/oder der Temperatur der Prozessluft durch einen der Prozessluft beigemischten Volumenstrom an Frischluft bietet außerdem den Vorteil, dass ein größerer Regelbereich für die Temperatur und/oder die Feuchte der Prozessluft zur Verfügung steht. Mit anderen Worten kann die Temperatur und/oder die Feuchte der Prozessluft in einem größeren Parameterbereich variiert werden.A regulation of the humidity and / or the temperature of the process air by a volume flow of fresh air admixed with the process air also offers the advantage that a larger control range is available for the temperature and / or the humidity of the process air. In other words, the temperature and / or the humidity of the process air can be varied within a larger parameter range.
Gemäß einer Ausführungsform ist vorgesehen, dass die Regelungseinheit so eingerichtet ist, dass der erste Volumenstromregler in einem insbesondere geschlossenen Regelkreis derart regelbar ist oder geregelt wird, dass der der Prozessluft zugeführte Volumenstrom an Frischluft so einstellbar ist oder eingestellt wird, dass die erfasste Temperatur des in der Prozesstrommel gelösten Tabakguts zumindest näherungsweise einem Temperatursollwert entspricht. Mit anderen Worten wird also die Temperatur des Tabakguts durch die Stellung des ersten Volumenstromreglers, bei dem es sich beispielsweise um eine Stell- oder Drosselklappe handelt, geregelt.According to one embodiment, it is provided that the control unit is set up such that the first volumetric flow controller is controllable or regulated in a closed loop in particular such that the volumetric flow of fresh air supplied to the process air can be set or adjusted so that the detected temperature of the in the process drum dissolved tobacco corresponds to at least approximately a temperature setpoint. In other words, therefore, the temperature of the tobacco is controlled by the position of the first volume flow regulator, which is for example a control or throttle.
Der Regelkreis der Einrichtung gemäß dieser Ausführungsform verwendet direkt die Temperatur des gelösten Tabakguts als Regelgröße. Die Temperatur des Tabakguts wird daher zuverlässiger und präziser eingestellt bzw. geregelt.The control circuit of the device according to this embodiment directly uses the temperature of the dissolved tobacco as a controlled variable. The temperature of the tobacco product is therefore adjusted more reliably and precisely.
In einer weiteren Ausführungsform ist eine zwischen der Ausbringseite und der Einbringseite der Prozesstrommel verlaufende Rückleitung zur Rückführung von Prozessluft in den Innenraum der Prozesstrommel vorgesehen, wobei eine Frischluftzuleitung mit der Rückleitung verbunden ist und der erste Volumenstromregler in der Frischluftzuleitung vorgesehen ist.In a further embodiment, a return line extending between the discharge side and the delivery side of the process drum for returning process air into the interior of the process drum is provided, wherein a fresh air supply line is connected to the return line and the first volume flow regulator is provided in the fresh air supply line.
Insbesondere handelt es sich bei dem Volumenstromregler um eine in der Frischluftzuleitung vorgesehene Drosselklappe, die auch als Frischluftklappe bezeichnet werden soll. Deren Klappenstellung bestimmt den von dem ersten Volumenstromregler geregelten Volumenstrom.In particular, the volume flow regulator is a throttle valve provided in the fresh air supply line, which is also to be referred to as a fresh air flap. Their flap position determines the volume flow controlled by the first volume flow controller.
Insbesondere wird diese Ausführungsform dadurch weitergebildet, dass ein Wärmetauscher in der Frischluftzuleitung vorgesehen ist, wobei die Regelungseinheit derart eingerichtet ist, dass der Wärmetauscher so regelbar ist oder geregelt wird, dass die zugeführte Frischluft eine konstante und insbesondere vorgegebene Temperatur aufweist.In particular, this embodiment is further developed in that a heat exchanger is provided in the fresh air supply line, wherein the control unit is set up such that the heat exchanger is regulated or regulated so that the supplied fresh air has a constant and in particular predetermined temperature.
Wird die Temperatur der Frischluft konstant gehalten, so ist es möglich, dass die Temperatur und/oder die Feuchte der Prozessluft ausschließlich durch den Volumenstrom der der Prozessluft zugeführten Frischluft bestimmt wird. Vorteilhaft ist ausschließlich der erste Volumenstromregler als Stellglied für den Regelkreis notwendig. In einer solchen Einrichtung ist die für die Prozessführung notwendige Kontrolle und Steuerung der Einrichtung gegenüber herkömmlichen Einrichtungen vereinfacht.If the temperature of the fresh air is kept constant, it is possible that the temperature and / or the humidity of the process air is determined exclusively by the volume flow of the fresh air supplied to the process air. Advantageously, only the first volume flow controller is required as an actuator for the control loop. In such a device, the necessary control and control of the device for the process control over conventional Facilities simplified.
Insbesondere ist die Einrichtung zum Lösen von Tabakgut gemäß einer weiteren Ausführungsform so ausgebildet, dass eine mit der Rückleitung gekoppelte Abluftleitung zur Abfuhr von Prozessluft vorgesehen ist, wobei in der Abluftleitung ein dritter Volumenstromregler vorgesehen ist, und wobei die Regelungseinheit derart eingerichtet ist, dass sie den ersten und den dritten Volumenstromregler so regelt, dass ein in der Frischluftzuleitung vorhandener Volumenstrom an Frischluft und ein in der Hauptabluftleitung vorhandener Volumenstrom der Abluft korrelieren, insbesondere linear korrelieren.In particular, the means for releasing tobacco material according to a further embodiment is designed so that a coupled to the return line exhaust pipe is provided for the removal of process air, wherein in the exhaust duct, a third volume flow regulator is provided, and wherein the control unit is arranged such that it the first and the third volumetric flow controller regulates such that a volume flow of fresh air present in the fresh air supply line and a volumetric flow of the exhaust air present in the main exhaust line correlate, in particular correlate linearly.
Mit anderen Worten ist die Einrichtung also dazu ausgelegt, dass ein kontinuierlicher Austausch der Prozessluft stattfindet. Da sich die Volumenströme der Frischluft und der Abluft, abgesehen von der kontinuierlich ausgetauschten Prozessluftmenge, gegenseitig kompensieren, wird vorteilhaft auf eine Haubendruckregelung verzichtet. Eine entsprechende Haube ist optional an der Ausbringseite der Prozesstrommel vorgesehen. Der Verzicht auf die Haubendruckregelung vereinfacht die Konstruktion und Steuerung der Einrichtung zum Lösen von Tabakgut. Ein beispielsweise vorhandener Offset zwischen dem Volumenstrom der Frischluft und dem Volumenstrom der Abluft sorgt dafür, dass die zusätzlich eingebrachte Luftmenge nicht an der Unterseite der Auslaufhaube austritt, sondern mit dem Brüden, also der beim Behandlungsvorgang entstehenden Luft, abgesaugt wird.In other words, the device is thus designed so that a continuous exchange of the process air takes place. Since the volume flows of the fresh air and the exhaust air, apart from the continuously exchanged process air amount, compensate each other, is advantageously dispensed with a dome pressure control. A corresponding hood is optionally provided on the delivery side of the process drum. The absence of the dome pressure control simplifies the design and control of the device for releasing tobacco. An example existing offset between the flow of fresh air and the volume flow of the exhaust air ensures that the additional amount of air introduced does not exit at the bottom of the outlet hood, but with the vapor, so the resulting air during the treatment process, is sucked.
Insbesondere zeichnet sich die Einrichtung zum Lösen von Tabakgut gemäß einer weiteren Ausführungsform dadurch aus, dass eine Fördereinrichtung zum Zuführen von Tabakgut in die Prozesstrommel vorgesehen ist, wobei die Regelungseinheit so eingerichtet ist, dass sie diese Fördereinrichtung und die Mittel zum Einbringen von Dampf und/oder Wasser so regelt, dass eine in die Prozessluft und/oder in den Innenraum der Prozesstrommel eingebrachte erste Masse an Dampf und/oder Wasser und eine zweite Masse des in die Prozesstrommel eingebrachten Tabakguts in einem konstanten Verhältnis stehen.In particular, the device for releasing tobacco material according to a further embodiment is characterized in that a conveying device is provided for feeding tobacco material into the process drum, wherein the regulating unit is set up in such a way that that it controls this conveyor and the means for introducing steam and / or water so that an introduced into the process air and / or in the interior of the process drum first mass of steam and / or water and a second mass of introduced into the process drum tobacco to stand in a constant relationship.
Bei der Fördereinrichtung handelt es sich vorzugsweise um ein taktgesteuertes Aufgabeband, in welches insbesondere eine Bandwaage integriert ist. Ein konstantes Tabak-zu-Dampf-Verhältnis ist im Hinblick auf eine vereinfachte Steuerung der Einrichtung zum Lösen von Tabakgut vorteilhaft, da diese mit einem kontinuierlichen Massestrom an Dampf betreibbar ist.The conveyor is preferably a clock-controlled feed belt, in which in particular a belt scale is integrated. A constant tobacco to vapor ratio is advantageous in view of a simplified control of the device for releasing tobacco material, since this is operable with a continuous mass flow of steam.
Im Rahmen der Erfindung ist ebenfalls vorzugsweise vorgesehen, dass im Innenraum der Prozesstrommel eine Sprinklereinheit vorgesehen ist, wobei mittels der Sprinklereinheit in der Prozesstrommel vorhandenes Tabakgut mit Flüssigkeit beaufschlagbar ist oder beaufschlagt wird, und wobei die Regelungseinheit dazu eingerichtet ist, ein von dieser Sprinklereinheit in die Behandlungstrommel eingebrachtes Flüssigkeitsvolumen so zu regeln, dass dieses Volumen und die in den Innenraum der Behandlungstrommel eingebrachte Masse an Tabakgut in einem konstanten Verhältnis stehen.In the context of the invention, it is also preferably provided that a Sprinkler unit is provided in the interior of the process drum, wherein liquid is present or acted upon by the sprinkler unit in the process drum tobacco material, and wherein the control unit is adapted to one of this sprinkler unit in the To regulate the treatment drum introduced volume of liquid so that this volume and introduced into the interior of the treatment drum mass of tobacco in a constant ratio.
Sowohl ein konstantes Verhältnis zwischen Dampf- und Tabakmenge sowie zwischen dem Volumen der eingebrachten Flüssigkeit und der Masse an Tabakgut erlaubt es, einen sehr konstanten Prozess zu fahren. Der Medienbedarf dieses Prozesses ist gleichmäßig, d.h. die von der Einrichtung abgefragte Menge an Dampf und Flüssigkeit sind zeitlich sehr konstant. Dies vereinfacht die Integration der Einrichtung zum Lösen von Tabakgut in eine Anlage der Tabak verarbeitenden Industrie.Both a constant ratio of steam and tobacco volume and between the volume of liquid introduced and the mass of tobacco material allows to drive a very constant process. The media requirement of this process is uniform, ie the amount of vapor and liquid interrogated by the device is very constant over time. This simplifies the integration of the device for releasing tobacco in a plant of the tobacco processing industry.
Zusammenfassend wird bei der Einrichtung zum Lösen von Tabakgut gemäß einer oder mehrerer der genannten Ausführungsformen lediglich ein Regelparameter verwendet. Dies ist die der Prozessluft zugeführte Menge an Frischluft. Die übrigen Prozessparameter, insbesondere die Temperatur der Frischluft, die dem Tabakgut zugeführte Masse an Dampf und/oder Wasser sowie das Volumen an Flüssigkeit, mit der das Tabakgut beaufschlagt wird, werden vorzugsweise konstant gehalten. Mit anderen Worten ist die Regelungseinheit insbesondere dazu eingerichtet, die Temperatur des gelösten Tabakguts ausschließlich durch den der Prozessluft zugeführten Volumenstrom an Frischluft zu regeln. Insbesondere wird der erste Volumenstromregler so geregelt, dass der Volumenstrom in der Frischluftleitung proportional zu dem Volumenstrom in der Abluftleitung ist. Im Gegensatz dazu verhält sich der Volumenstrom in der Prozessluftrückleitung antiproportional zu demjenigen an der Frischluft.In summary, only one control parameter is used in the device for releasing tobacco according to one or more of the aforementioned embodiments. This is the amount of fresh air supplied to the process air. The remaining process parameters, in particular the temperature of the fresh air, the mass of steam and / or water supplied to the tobacco product and the volume of liquid with which the tobacco material is applied, are preferably kept constant. In other words, the control unit is set up in particular to regulate the temperature of the dissolved tobacco product exclusively by the volume flow of fresh air supplied to the process air. In particular, the first volume flow controller is controlled so that the volume flow in the fresh air line is proportional to the volume flow in the exhaust air line. In contrast, the volume flow in the process air return behaves antiproportional to that of the fresh air.
Wie weiter oben bereits erwähnt, besteht der Regelmechanismus darin, die Wasserbeladung der Prozessluft und damit ihre relative Feuchte über das Mischungsverhältnis der Prozessluft mit der zugeführten Frischluft zu verändern. Zu diesem Zweck wird ein mehr oder weniger großer Volumenstrom an Frischluft der Prozessluft zugeführt. Damit die Menge der Prozessluft nicht verändert wird, werden der Anteil der zirkulierenden Prozessluft und der Volumenstrom der abgeführten Abluft entsprechend angepasst.As already mentioned above, the control mechanism is to change the water loading of the process air and thus its relative humidity via the mixing ratio of the process air with the fresh air supplied. For this purpose, a more or less large volume flow of fresh air is supplied to the process air. So that the amount of process air is not changed, the proportion of circulating process air and the volume flow of discharged exhaust air are adjusted accordingly.
Gemäß einer weiteren vorteilhaften Ausführungsform ist der Temperatursensor ein erster kontaktlos arbeitender Temperatursensor und/oder ein zweiter Temperatursensor, welcher in ein Bauteil integriert ist, das zumindest mittelbar mit dem an der Ausbringöffnung ausgebrachten, gelösten Tabakgut in thermischem Kontakt steht.According to a further advantageous embodiment, the temperature sensor is a first non-contact temperature sensor and / or a second temperature sensor, which is integrated into a component which is in thermal contact, at least indirectly, with the dissolved tobacco material applied to the dispensing opening.
Der zweite Temperatursensor ist beispielsweise in einer Förderrinne und/oder in einer Auslaufhaube vorgesehen. Denkbar ist, dass der zweite Temperatursensor zumindest mittelbar in thermischem Kontakt mit dem gelösten Tabakgut steht, z.B. in der Förderrinne angeordnet ist, die insbesondere zur Aufnahme von aus der Ausbringöffnung ausgebrachtem gelöstem Tabakgut vorgesehen ist.The second temperature sensor is provided for example in a conveyor trough and / or in a discharge hood. It is conceivable that the second temperature sensor is at least indirectly in thermal contact with the dissolved tobacco product, e.g. is arranged in the conveyor trough, which is provided in particular for receiving discharged from the discharge opening dissolved tobacco product.
Vorteilhaft wird die Temperatur des ausgeförderten und gelösten Tabakguts mit dem ersten und/oder dem zweiten Temperatursensor präzise und schnell erfasst, so dass die Temperatur und/oder die Feuchte der Prozessluft mit hoher Genauigkeit angepasst werden.Advantageously, the temperature of the discharged and dissolved tobacco product with the first and / or the second temperature sensor is detected precisely and quickly, so that the temperature and / or the humidity of the process air can be adjusted with high accuracy.
Die erfindungsgemäße Aufgabe wird außerdem gelöst durch ein Verfahren zum Lösen von Tabakgut in einer Prozesstrommel mit einer an einer Einbringseite vorgesehenen Einbringöffnung und einer an einer Ausbringseite vorgesehenen Ausbringöffnung, wobei das Tabakgut in einen Innenraum der Prozesstrommel durch die Einbringöffnung eingebracht wird und gelöstes Tabakgut mit einer bestimmten Temperatur an der Ausbringöffnung aus dem Innenraum der Prozesstrommel ausgebracht wird, und wobei dem Innenraum der Prozesstrommel Prozessluft zugeführt wird und insbesondere in die Prozessluft und/oder in den Innenraum der Prozesstrommel Dampf und/oder Wasser eingebracht wird, wobei das in der Prozesstrommel vorhandene Tabakgut mit der Prozessluft beaufschlagt wird, und wobei das Verfahren dadurch weitergebildet ist, dass die Temperatur des gelösten Tabakguts erfasst wird und in Abhängigkeit von der erfassten Temperatur des Tabakguts ein bestimmter Volumenstrom an Frischluft der Prozessluft beigemischt wird, um die Temperatur des gelösten Tabakguts zu beeinflussen.The object of the invention is also achieved by a method for releasing tobacco in a process drum having a supply opening provided on a Einbringseite and provided on a Ausbringseite discharge opening, wherein the tobacco is introduced into an interior of the process drum through the insertion opening and dissolved tobacco with a specific Temperature at the discharge opening is discharged from the interior of the process drum, and wherein the process air is supplied to the interior of the process drum and in particular in the process air and / or in the interior of the process drum steam and / or water is introduced, wherein the present in the process drum with tobacco the process air is acted upon, and wherein the method is further developed in that the temperature of the dissolved tobacco product is detected and depending on the detected temperature of the tobacco material a certain volume flow of fresh air of the process air be is mixed to influence the temperature of the dissolved tobacco.
Weiterhin zeichnet sich das Verfahren bevorzugt dadurch aus, dass ein der Prozessluft zugeführter Volumenstrom an Frischluft in einem insbesondere geschlossenen Regelkreis so geregelt wird, dass die erfasste Temperatur des gelösten Tabakguts zumindest näherungsweise einem Temperatursollwert entspricht.Furthermore, the method is preferably characterized in that one of the process air supplied volume flow of fresh air in a closed loop in particular is controlled so that the detected temperature of the dissolved tobacco material corresponds at least approximately to a temperature setpoint.
Gemäß einer weiteren vorteilhaften Ausführungsform wird die der Prozessluft beigemischte Frischluft auf eine vorgegebene, insbesondere konstante, Temperatur temperiert, insbesondere erwärmt.According to a further advantageous embodiment, the fresh air added to the process air is heated to a predetermined, in particular constant, temperature, in particular heated.
In einer weiteren vorteilhaften Ausführungsform wird in den Innenraum der Prozesstrommel eine erste Masse an Tabakgut und in die Prozessluft und/oder in den Innenraum der Prozesstrommel eine zweite Masse an Dampf und/oder Wasser eingebracht, wobei die erste und die zweite Masse in einem konstanten Verhältnis zueinander stehen.In a further advantageous embodiment, a first mass of tobacco material and in the process air and / or in the interior of the process drum a second mass of steam and / or water is introduced into the interior of the process drum, wherein the first and the second mass in a constant ratio to stand by each other.
Ferner wird gemäß einer Ausführungsform in den Innenraum der Prozesstrommel eine Flüssigkeit eingebracht, wobei das Tabakgut mit dieser Flüssigkeit beaufschlagt wird, und wobei ein Volumen der eingebrachten Flüssigkeit und eine in die Prozesstrommel eingebrachte Masse an Tabakgut in einem festen Verhältnis zueinander stehen.Furthermore, according to one embodiment, a liquid is introduced into the interior of the process drum, whereby the tobacco material is charged with this liquid, and a volume of the introduced liquid and a mass of tobacco material introduced into the process drum are in a fixed relationship to one another.
Gleiche oder ähnliche Vorteile, wie sie bereits im Hinblick auf die Einrichtung zum Lösen von Tabakgut im Zusammenhang mit einer oder mehreren Ausführungsformen erwähnt wurden, treffen in gleicher oder ähnlicher Weise auch auf das Verfahren zum Lösen von Tabakgut zu und sollen daher nicht wiederholt werden.The same or similar advantages as already mentioned with regard to the device for releasing tobacco in connection with one or more embodiments, apply in the same or similar manner to the method for releasing tobacco and are therefore not to be repeated.

Zur Regelung der Volumenströme in der Frischluftleitung 22, der Rückleitung 16 und in der Hauptabluftleitung 28 sind in die jeweiligen Leitungen ein erster bis dritter Volumenstromregler 36, 38, 40 vorgesehen. Die Volumenstromregler sind mit der Regelungseinheit 42 verbunden.With the process air leading
Die Regelungseinheit 42 ist dazu eingerichtet, den Volumenstrom der Frischluft durch entsprechende Ansteuerung des ersten Volumenstromreglers 36 so zu regeln, dass sich der Volumenstrom der Frischluft und der Volumenstrom der Abluft, welcher durch die Stellung des dritten Volumenstromreglers 40 bestimmt ist, im Wesentlichen gegenseitig kompensieren. Mit anderen Worten ist der erste Volumenstromregler 36 und der dritte Volumenstromregler 40 zumindest näherungsweise synchron angesteuert. In der Regelung kann insbesondere eine Geradengleichung zwischen der Position der Frischluftklappe FL und der Abluftklappe AL hinterlegt sein, welche sich in der Stellung des ersten Volumenstromreglers 36 und der Stellung des dritten Volumenstromreglers 40 widerspiegelt.The
Diese Regelung der Frischluftklappe FL und der Abluftklappe AL dient dazu, dass die zusätzlich zugeführte Luftmenge nicht unten an der Haube 12 ausweht, sondern mit den Brüden abgesaugt wird.This regulation of the fresh air flap FL and the exhaust air flap AL serves to ensure that the additionally supplied air volume is not at the bottom the
Der erste Volumenstromregler 36 und der zweite Volumenstromregler 38, welcher den Volumenstrom der Prozessluft PL bestimmt, sind hingegen gegenläufig angesteuert. Durch die beschriebene Ansteuerung des ersten bis dritten Volumenstromreglers 36, 38, 40 wird der Prozessluft, abhängig von der Stellung des ersten Volumenstromreglers 36, an der Anschlussstelle 48 eine bestimmte Menge an Frischluft beigemischt.The first
Die Prozessluft wird insbesondere kontinuierlich mit Hilfe des Gebläses 20 gefördert. Die der Anlage zugeführte Frischluft A wird weiterhin bevorzugt im Wärmetauscher 24 auf eine konstante, und insbesondere vorbestimmte Temperatur temperiert und insbesondere erwärmt. Zu diesem Zweck ist der Wärmetauscher 24 an eine Frischdampfleitung 50 angeschlossen, welche mit Dampf S gespeist wird. Der Wärmetauscher 24 zur Erwärmung der Frischluft A ist weiterhin insbesondere durch einen Regelkreis, umfassend in Temperatursensor 56, eine Integral-Proportionalregelung 57 und ein Steuerventil 58, geregelt. Im Wärmetauscher 24 anfallendes Kondensat C wird aus der Anlage abgezogen.The process air is in particular continuously conveyed by means of the

Aus dem Diagramm der
Während einer Aufheizphase I ist die Frischluftklappe FL vollständig geschlossen. Die Prozessluftklappe PL ist hingegen vollständig geöffnet. Die Prozessluft wird während der Aufheizphase durch die Rückleitung 16 und den Innenraum der Prozesstrommel 4 zirkuliert und kontinuierlich erwärmt. Während der Aufheizphase steigt die Temperatur des Tabakguts kontinuierlich an, bis seine Temperatur die angestrebte Solltemperatur (horizontale gestrichelte Linie; Bezugszeichen 42) erreicht hat. Da zu Beginn dieser Phase noch kein Tabakgut durch die Prozesstrommel 4 gefördert wird, kann die Temperaturregelung anhand der Prozesslufttemperatur durchgeführt werden.During a heating phase I, the fresh air flap FL is completely closed. The process air flap PL, however, is completely open. The process air is circulated through the
In der sich anschließenden Anlaufphase II wird der Prozessluft zunehmend Frischluft beigemischt. Entsprechend wird die Frischluftklappe FL geöffnet, während die Prozessluftklappe PL zunehmend geschlossen wird. Die Abluftklappe AL wird im Wesentlichen proportional zu der Frischluftklappe FL gesteuert, wobei die Möglichkeit besteht, einen konstanten Offset einzuhalten oder in der Regelung eine Geradengleichung zu hinterlegen. Somit öffnet sich gemeinsam mit der Frischluftklappe FL auch die Abluftklappe AL.In the subsequent start-up phase II, the process air is increasingly mixed with fresh air. Accordingly, the fresh air flap FL is opened while the process air flap PL is increasingly closed. The exhaust air flap AL is controlled substantially in proportion to the fresh air flap FL, with the possibility of keeping a constant offset or in the control to define a straight-line equation. Thus opens together with the fresh air flap FL and the exhaust air flap AL.
In etwa in der Mitte des Bereiches II unterschreitet die gemessene Temperatur (Bezugszeichen 60) des gelösten Tabakguts T* den Temperatursollwert (Bezugszeichen 62). Dies hat zur Folge, dass der Frischluftanteil an der Prozessluft zurückgefahren wird, was bedeutet dass die Frischluftklappe FL weiter geschlossen und die Prozessluftklappe PL erneut weiter geöffnet wird.In about the middle of the region II, the measured temperature (reference numeral 60) of the dissolved tobacco T * falls below the temperature setpoint (reference numeral 62). This has the consequence that the fresh air content is reduced to the process air, which means that the fresh air flap FL further closed and the process air flap PL is opened again.
Im Bereich III ist schließlich ein stabiler Zustand erreicht, die Klappenstellungen der Frischluftklappe FL, Abluftklappe AL und Prozessluftklappe PL unterliegen lediglich geringen Schwankungen. Die tatsächliche Temperatur des gelösten Tabakguts T* kann bis auf geringe Abweichungen an den angestrebten Sollwert 62 herangeregelt werden.In area III finally a stable state is reached, the flap positions of the fresh air flap FL, exhaust air flap AL and process air flap PL are subject to only slight fluctuations. The actual temperature of the dissolved tobacco T * can be adjusted to a small deviation from the desired
