The vacuum channels of the upper sealing station (1) are connected to the vacuum channels of the lower sealing tool (2) by means of an adapter (13) in a fluid-tight manner. The fluid circuit is closed by a pump (14), a fluid container (15) and the associated pipes, which are connected to the flanges (11), (12). Said pump (14) pumps a cleaning and disinfecting fluid, in the present case active chlorine, into the vacuum channels of the upper sealing station (1).

Description

Die vorliegende Erfindung betrifft ein Verfahren zur Reinigung und/oder Desinfizierung der Vakuumkanäle einer Siegelstation, bei dem die Vakuumkanäle in regelmäßigen Abständen von der Vakuumpumpe getrennt und an einen Reinigungs- und/oder Desinfizierungskreislauf angeschlossen werden.The present invention relates to a method for cleaning and / or disinfecting the vacuum channels of a sealing station, in which the vacuum channels are separated from the vacuum pump at regular intervals and connected to a cleaning and / or disinfecting circuit.

An die Hygiene von Verpackungsmaschinen wie sie erispielsweise in der EP 1 094 003 A1 beschrieben ist, insbesondere im Lebensmittelbereich, werden heutzutage immer höhere Anforderungen gestellt. Dem entsprechend muß sichergestellt sein, daß alle Teile der Verpackungsmaschine, die direkt oder indirekt mit dem Verpackungsgut in Berührung kommen, in regelmäßigen Abständen gereinigt und desinfiziert werden. Dies gilt auch für die Vakuumkanäle der Siegelstation, mit denen die Luft aus den Verpackungen abgezogen und beispielsweise durch Inertgas ersetzt wird. Beim Abziehen der Luft werden häufig kleine Lebensmittelpartikel mitgerissen, die sich in den Vakuumkanälen ablagern und insbesondere während Stillstandszeiten der Verpackungsmaschine die Keimbildung in diesen Vakuumkanälen fördern.To the hygiene of packing machines as for example in the EP 1 094 003 A1 is described, especially in the food industry, nowadays more and more demands are made. Accordingly, it must be ensured that all parts of the packaging machine, which come into direct or indirect contact with the packaged goods, are cleaned and disinfected at regular intervals. This also applies to the vacuum channels of the sealing station, with which the air is removed from the packaging and replaced for example by inert gas. When removing the air small food particles are often entrained, which are deposited in the vacuum channels and promote especially during downtime of the packaging machine, the nucleation in these vacuum channels.

Aufgabe der vorliegenden Erfindung war es deshalb, ein Verfahren zur Reinigung und/oder Desinfizierung der Vakuumkanäle zur Verfügung zu stellen.Object of the present invention was therefore to provide a method for cleaning and / or disinfecting the vacuum channels available.

Gelöst wird die Aufgabe durch ein Verfahren nach Patentanspruch 1.The problem is solved by a method according to claim 1.

Es war für den Fachmann überaus erstaunlich und nicht zu erwarten, daß es durch das erfindungsgemäße Verfahren gelingt, wesentlich keimfreiere und damit haltbarere Lebensmittel herzustellen als dies mit Maschinen gemäß dem Stand der Technik möglich war. Das erfindungsgemäße Verfahren kann einfach und kostengünstig beispielsweise nach dem täglichen Betrieb der Maschine vor einer nächtlichen Stillstandszeit durchgeführt werden.It was extremely surprising for the person skilled in the art and it was not to be expected that the process according to the invention would make it possible to produce substantially germ-free and thus more durable foods than was possible with state-of-the-art machines. The inventive method can be simple and cost-effective, for example, after the daily operation of the machine are carried out before a nocturnal downtime.

In einer bevorzugten Ausführungsform der vorliegenden Erfindung weist der Reinigungskreislauf eine Pumpe und ein Flüssigkeitsreservoir auf. In dem Flüssigkeitsreservoir befindet sich eine Reinigungs- und/oder Desinfektionsflüssigkeit, beispielsweise aktiv Chlor, die mit der Pumpe durch die Vakuumkanäle gepumpt wird und aus den Vakuumkanälen wieder in das Flüssigkeitsreservoir läuft. Dieser Kreislauf wird solange aufrechterhalten, bis sichergestellt ist, daß die Vakuumkanäle hinreichend gereinigt und/oder desinfiziert sind.In a preferred embodiment of the present invention, the cleaning circuit comprises a pump and a liquid reservoir. In the liquid reservoir is a cleaning and / or disinfecting liquid, for example, active chlorine, which is pumped by the pump through the vacuum channels and runs from the vacuum channels back into the liquid reservoir. This cycle is maintained until it is ensured that the vacuum channels are sufficiently cleaned and / or disinfected.

Eine Siegelstation weist ein erstes und ein zweites Siegelwerkzeug auf, die so zusammenwirken, daß eine Deckelfolie auf eine Verpackungsmulde gesiegelt wird. Dabei ist ein erstes Siegelwerkzeug oberhalb der Deckelfolie und ein zweites Siegelwerkzeug unterhalb der Verpackungsmulde angeordnet. Das zweite Siegelwerkzeug ist in der Regel höhenverstellbar.A sealing station has first and second sealing tools which cooperate to seal a lidding film to a packaging tray. In this case, a first sealing tool above the lid film and a second sealing tool below the packaging tray is arranged. The second sealing tool is usually height adjustable.

In einer erfindungsgemäßen Ausführungsform der vorliegenden Erfindung werden das erste und das zweite Siegelwerkzeug unabhängig voneinander an einen Reinigungs-und/oder Desinfizierungskreislauf angeschlossen. Diese Ausführungsform hat den Vorteil, daß die Vakuumkanäle des ersten, oberen Siegelwerkzeuges, in denen sich öfter Speisereste ablagern, häufiger gereinigt werden kann als die Vakuumkanäle des zweiten, unteren Siegelwerkzeuges.In one embodiment of the present invention, the first and second sealing tools are independently connected to a cleaning and / or disinfecting circuit. This embodiment has the advantage that the vacuum channels of the first upper sealing tool, in which food residues are deposited more often, can be cleaned more frequently than the vacuum channels of the second, lower sealing tool.

In einer anderen erfindungsgemäßen Ausführungsform des erfindungsgemäßen Verfahrens weist die Siegelstation ein erstes und ein zweites Siegelwerkzeug auf, die an einen Reinigungs- und/oder Desinfizierungskreislauf angeschlossen werden und die durch einen Adapter miteinander verbunden sind. Durch den Adapter wird eine flüssigkeitsdichte Verbindung zwischen den Vakuumkanälen des ersten und des zweiten Siegelwerkzeuges erzeugt, so daß mit einem Flüssigkeitskreislauf beide Siegelwerkzeuge nacheinander mit der Reinigungs- und/oder Desinfizierungsflüssigkeit durchspült werden können. Diese Ausführungsform des erfindungsgemäßen Verfahrens ist besonders einfach durchzuführen und bedarf nur eines geringen Umbaus der Verpackungsmaschine.In another embodiment of the method according to the invention, the sealing station has a first and a second sealing tool, which are connected to a cleaning and / or disinfecting circuit and which are connected to one another by an adapter. Through the adapter, a liquid-tight connection between the vacuum channels of the first and the second sealing tool is generated, so that with a fluid circuit both sealing tools can be washed through successively with the cleaning and / or disinfecting liquid. This embodiment of the The method according to the invention is particularly simple to carry out and requires only a minor modification of the packaging machine.

Als Reinigungs- und/oder Desinfizierungsflüssigkeit kann jede dem Fachmann bekannte Reinigungs- und/oder Desinfizierungsflüssigkeit eingesetzt werden, mit der es gelingt, die Kanäle zu reinigen und gegebenenfalls zu desinfizieren. Vorzugsweise wird jedoch als Reinigungs- und/oder Desinfizierungsflüssigkeit aktiv Chlor eingesetzt.As cleaning and / or disinfecting liquid, any cleaning and / or disinfecting liquid known to those skilled in the art can be used, with which it is possible to clean the channels and, if necessary, to disinfect them. Preferably, however, chlorine is used as the cleaning and / or disinfecting liquid.

Vorzugsweise wird der Reinigungs- und/oder Desinfizierungskreislauf nach der Reinigung und/oder Desinfizierung wieder abgekoppelt. Keimfreie Druckluft wird dann so lange durch die Vakuumkanäle gefördert, bis diese getrocknet sind, so daß bei dem sich anschließenden Verpackungsprozeß keine Reinigungs- und/oder Desinfizierungsflüssigkeit in die zu verpackenden Lebensmittel gelangt.Preferably, the cleaning and / or disinfecting cycle is disconnected again after cleaning and / or disinfecting. Germ-free compressed air is then transported through the vacuum channels until they are dried, so that in the subsequent packaging process no cleaning and / or disinfecting liquid enters the food to be packaged.

Im folgenden wird die Erfindung anhand der Figuren 1 bis 3 erläutert, Diese Erläuterungen sind lediglich beispielhaft und schränken den allgemeinen Erfindungsgedanken nicht ein.

  • Figur 1 zeigt ein Verfahrensbild zur Erzeugung eines Vakuums in dem ersten und zweiten Siegelwerkzeug.
  • Figur 2 zeigt das erfindungsgemäße Verfahren, bei dem das erste und das zweite Siegelwerkzeug an einen Reinigungs- und Desinfizierungskreislauf angeschlossen ist.
  • Figur 3 zeigt eine Ausführungsform des erfindungsgemäßen Verfahrens, bei dem das obere und das untere Siegelwerkzeug getrennt voneinander an einen Reinigungs- und Desinfizierungskreislauf angeschlossen ist.
In the following the invention is based on the FIGS. 1 to 3 These explanations are merely exemplary and do not limit the general inventive concept.
  • FIG. 1 shows a method image for creating a vacuum in the first and second sealing tool.
  • FIG. 2 shows the inventive method in which the first and the second sealing tool is connected to a cleaning and disinfecting circuit.
  • FIG. 3 shows an embodiment of the method according to the invention, in which the upper and the lower sealing tool is connected separately to a cleaning and disinfecting circuit.

Figur 1 zeigt ein Verfahrensschema zur Evakuierung der Vakuumkanäle einer Siegelstation gemäß dem Stand der Technik. Die Siegelstation weist ein oberes Siegelwerkzeug 1 und ein unteres Siegelwerkzeug 2 auf. In diese Siegelwerkzeuge sind Kanäle eingearbeitet, durch die die Luft aus der Verpackung abgesaugt werden kann. Diese Absaugung erfolgt über die Vakuumpumpe 3. Mit den Ventilen 4 bis 7 wird der von der Vakuumpumpe 3 erzeugte Unterdruck in gewünschter Weise auf die Vakuumkanäle des oberen Siegelwerkzeuges 1 und die Vakuumkanäle des unteren Siegelwerkzeuges 2 verteilt. Nach vollendeter Siegelung erfolgt ein Entspannung des Unterdrucks über die Ventile 8 und 9. FIG. 1 shows a process scheme for the evacuation of the vacuum channels of a sealing station according to the prior art. The sealing station has an upper sealing tool 1 and a lower sealing tool 2. In these sealing tools Channels are incorporated, through which the air can be sucked out of the packaging. This suction takes place via the vacuum pump 3. With the valves 4 to 7, the vacuum generated by the vacuum pump 3 is distributed in a desired manner to the vacuum channels of the upper sealing tool 1 and the vacuum channels of the lower sealing tool 2. After completion of the seal, a relaxation of the negative pressure takes place via the valves 8 and 9.

Figur 2 zeigt ein Schema des erfindungsgemäßen Verfahrens, bei dem ein Reinigungs- und Desinfizierungskreislauf für die Vakuumkanäle des oberen Siegelwerkzeuges 1 und des unteren Siegelwerkzeuges 2 errichtet worden ist. In dem vorliegenden Fall ist die Vakuumpumpe 3 abgeschaltet worden und die Verbindungsleitung zu der Siegelstation an der Stelle 10 abgedichtet oder abgeflanscht worden. Die Vakuumkanäle der oberen Siegelstation 1 sind durch ein Adapter 13 mit den Vakuumkanälen des unteren Siegelwerkzeuges 2 flüssigkeitsdicht verbunden worden. Der Flüssigkeitskreislauf wird durch eine Pumpe 14, ein Flüssigkeitsreservoir 15 und die dazugehörigen Rohrleitungen, die an die Flansche 11, 12 angeflanscht sind, geschlossen. Die Pumpe 14 pumpt eine Reinigungs- und Desinfizierungsflüssigkeit, in dem vorliegenden Fall aktiv Chlor, in die Vakuumkanäle des oberen Siegelwerkzeuges 1. Von dort läuft die Flüssigkeit durch den Adapter 13 in die Vakuumkanäle des unteren Siegelwerkzeuges 2 und wird von dort in das Flüssigkeitsreservoir 15 zurückgeführt, um erneut an dem Reinigungs- und/oder Desinfizierungsprozeß teilnehmen zu können. Dieser Flüssigkeitskreislauf wird solange aufrechterhalten, bis die Vakuumkanäle hinreichend gereinigt und desinfiziert sind. Zur Reinigung und/oder Desinfizierung des Ventils 5 und der dazugehörigen Rohrleitungen wird das Ventil 4 vollständig geschlossen, so daß sich lediglich ein Flüssigkeitskreislauf durch die Ventile 5, 6 und 7 aufbaut. Nach Beendigung der Reinigung bzw. Desinfektion werden die Pumpe 14 und das Flüssigkeitsreservoir 15 wieder von den Rohrleitungen der Evakuierung abgekoppelt und die Vakuumpumpe 3 wieder angeschlossen. Des weiteren wird der Adapter 13 entfernt. Durch die Vakuumkanäle der Siegelwerkzeuge 1, 2 wird so lange keimfreie Luft gefördert, bis diese vollständig getrocknet sind, so daß keine Reinigungs- und Desinfizierungsflüssigkeit in die zu verpackenden Lebensmittel gelangen kann. FIG. 2 shows a diagram of the method according to the invention, in which a cleaning and disinfecting circuit for the vacuum channels of the upper sealing tool 1 and the lower sealing tool 2 has been established. In the present case, the vacuum pump 3 has been switched off and the connecting line to the sealing station has been sealed or flattened at location 10. The vacuum channels of the upper sealing station 1 have been liquid-tightly connected by an adapter 13 with the vacuum channels of the lower sealing tool 2. The liquid circuit is closed by a pump 14, a liquid reservoir 15 and the associated piping, which are flanged to the flanges 11, 12. The pump 14 pumps a cleaning and disinfecting liquid, in the present case active chlorine in the vacuum channels of the upper sealing tool 1. From there, the liquid passes through the adapter 13 in the vacuum channels of the lower sealing tool 2 and is returned from there into the liquid reservoir 15 to participate again in the cleaning and / or disinfecting process. This fluid circuit is maintained until the vacuum channels are sufficiently cleaned and disinfected. For cleaning and / or disinfecting the valve 5 and the associated piping, the valve 4 is completely closed, so that only builds a fluid circuit through the valves 5, 6 and 7. After completion of the cleaning or disinfection, the pump 14 and the liquid reservoir 15 are again disconnected from the evacuation pipelines and the vacuum pump 3 is reconnected. Furthermore, the adapter 13 is removed. Through the vacuum channels of the sealing tools 1, 2 so long germ-free air is conveyed until they are completely dried, so that no cleaning and disinfecting liquid can get into the food to be packaged.

In Figur 3 ist jeweils ein Reinigungs- und Desinfizierungskreislauf für die Vakuumkanäle des oberen Siegelwerkzeuges 1 und die Vakuumkanäle des unteren Siegelwerkzeuges 2 dargestellt. Im wesentlichen treffen auf diese Ausführungsform des erfindungsgemäßen Verfahrens die Erläuterungen gemäß Figur 2 zu, nur daß in dem vorliegenden Fall durch die Adapter 13, 13` keine Verbindung zwischen den Vakuumkanälen des oberen Siegelwerkzeuges 1 und des untere Siegelwerkzeuges 2 hergestellt wird. Dadurch können die Vakuumkanäle des oberen Siegelwerkzeuges unabhängig von den Vakuumkanälen des unteren Siegelwerkzeuges gereinigt werden und umgekehrt. Diese Ausführungsform des vorliegenden Verfahrens ist insbesondere dann zweckmäßig, wenn die Vakuumkanäle des oberen Siegelwerkzeuges stärker verschmutzt sind als die Vakuumkanäle des unteren Siegelwerkzeuges, was oftmals der Fall ist.In FIG. 3 In each case, a cleaning and disinfecting circuit for the vacuum channels of the upper sealing tool 1 and the vacuum channels of the lower sealing tool 2 is shown. Essentially, the explanation according to this embodiment of the method according to the invention FIG. 2 to, except that in the present case by the adapter 13, 13 'no connection between the vacuum channels of the upper sealing tool 1 and the lower sealing tool 2 is made. As a result, the vacuum channels of the upper sealing tool can be cleaned independently of the vacuum channels of the lower sealing tool and vice versa. This embodiment of the present method is particularly useful when the vacuum channels of the upper sealing tool are more contaminated than the vacuum channels of the lower sealing tool, which is often the case.
