Description

Verfahren zum Verarbeiten, insbesondere zum Verpacken von Produkten unter Verwendung eines sauerstofffreien Prozessgases Process for processing, in particular for packaging products using an oxygen-free process gas

Die Erfindung bezieht sich auf ein Verfahren gemäß Oberbegriff Patentanspruch 1 , auf eine Anlage zum Durchführen dieses Verfahrens gemäß Oberbegriff Patentanspruch 9 sowie auch auf die Verwendung eines Gasfilters, insbesondere eines Membranfilters bei einer Anlage zum Verarbeiten, insbesondere Verpacken von sauerstoffempfindlichen Produkten entsprechend Oberbegriff Patentanspruch 15.The invention relates to a method according to the preamble of claim 1, to a system for performing this method according to the preamble of claim 9 and also to the use of a gas filter, in particular a membrane filter in a plant for processing, in particular packaging of oxygen-sensitive products according to the preamble of claim 15.

Bei einer Vielzahl von Produkten, auch bei vielen Getränken besteht das Problem, dass die Haltbarkeit und/oder Qualität und/oder der Geschmack solcher Produkte durch Luft bzw. durch den in der Luft enthaltenen Sauerstoff ( O, O2, 03) stark beeinträchtigt werden können. Ein derartiger Sauerstoffeintrag erfolgt beispielsweise während des Verpackens oder während des Füllens eines Packmittels mit dem betreffenden Produkt und/oder nach dem Verpacken und vor und/oder während des Verschließens des verwendeten Packmittels.The problem with a large number of products, even with many beverages, is that the durability and / or quality and / or the taste of such products can be severely impaired by air or by the oxygen (O, O 2, O 3) present in the air , Such an oxygen input takes place, for example, during packaging or during the filling of a packaging with the product in question and / or after packaging and before and / or during the closing of the packaging used.

Um hier Abhilfe zu schaffen, ist es bekannt, die Verarbeitung von derartigen, sauerstoffempfindlichen Produkten unter Verwendung eines in der Regel von CO2 gebildeten Prozessgases durchzuführen, wobei dieses Prozessgas beispielsweise zur Erzeugung einer Schutz- oder Inertgas-Atmosphäre verwendet wird, in der die Verarbeitung, beispielsweise das Füllen des jeweiligen Packmittels mit dem Produkt sowie das Verschließen des Packmittels erfolgen. Weiterhin ist es auch bekannt, Packmittel vor dem Füllen mit dem als Prozessgas verwendeten CO∑-Gas zu spülen. Dieses Spülen dient dazu, die innerhalb der noch unbefüllten Verpackung enthaltene Umgebungsluft, und damit den in dieser Luft enthaltenen Sauerstoff vollständig oder nahezu vollständig aus der Verpackung zu entfernen, und durch eine sauerstofffreies Prozessgas zu ersetzen.To remedy this situation, it is known to carry out the processing of such oxygen-sensitive products using a process gas usually formed by CO 2 , this process gas is used for example to generate a protective or inert gas atmosphere in which the processing For example, the filling of the respective packaging with the product and the closing of the packaging done. Furthermore, it is also known to flush packaging before filling with the COΣ gas used as the process gas. This rinsing serves to completely or almost completely remove the ambient air contained in the still unfilled packaging, and thus the oxygen contained in this air from the packaging, and to replace it with an oxygen-free process gas.

Nachteilig hierbei ist, dass das als Prozessgas verwendete Inertgas einen nicht unerheblichen Kostenfaktor darstellt. Dieses hat u.a. zur Folge, dass der Einsatz des Inertgases bei bekannten Anlagen nur gezielt an wenigen, hochkritischen Stellen erfolgt.The disadvantage here is that the inert gas used as a process gas represents a not inconsiderable cost factor. This has u.a. As a result, the use of the inert gas in known systems only takes place selectively at a few, highly critical points.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden. Zur Lösung dieser Aufgabe ist ein Verfahren entsprechend dem Patentanspruch 1 ausgebildet. Eine Anlage zum Durchführen des Verfahrens ist Gegenstand des Patentanspruchs 9. Die Verwendung eines Gasfraktionierers oder Gasfilters, insbesondere eines Membranfilters, ist Gegenstand des Patentanspruchs 15.The invention has for its object to avoid these disadvantages. To solve this problem, a method according to claim 1 is formed. A plant for carrying out the method is the subject of claim 9. The use of a gas fractionator or gas filter, in particular a membrane filter is the subject of claim 15.

Unter "sauerstoffempfindliches Produkt" sind im Sinne der vorliegenden Erfindung Produkte unterschiedlichster Art und unterschiedlichster Konsistenz zu verstehen, die durch Einschluss oder Eintrag von Sauerstoff hinsichtlich ihrer Haltbarkeit und/oder ihrer Qualität und/oder ihres Geschmacks usw., aber auch hinsichtlich ihrer Verwendbarkeit und Brauchbarkeit bzw. Wirkung beeinträchtig werden. "Packmittel" im Sinne der Erfindung sind insbesondere Flaschen, Tuben, Dosen, Gläser, Eimer oder dergleichen Behälter, aber auch aus Flachmaterial, beispielsweise aus mehrlagigem Flachmaterial, z.B. durch Falten erzeugte Packmittel, wie Weichverpackungen, Beutel usw.For the purposes of the present invention, the term "oxygen-sensitive product" is to be understood as meaning products of the most varied types and consistencies, including the inclusion or addition of oxygen in terms of their durability and / or quality and / or taste, etc., but also with regard to their usability and usefulness or effect are impaired. "Packaging" within the meaning of the invention are in particular bottles, tubes, cans, jars, buckets or similar containers, but also from flat material, for example, from multilayer flat material, for example by folding produced packaging, such as soft packaging, bags, etc.

"Sauerstofffreies oder im Wesentlichen sauerstofffreies Prozessgas" im Sinne der Erfindung ist ein Gas, welches wenigstens eine durch Fraktionierung von Umgebungs- oder Atmosphärenluft erhaltene Komponente, die keinen Sauerstoff (O2, auch O oder O3) oder aber allenfalls nur einen so geringen, vernachlässigbaren Sauerstoffanteil enthält, der zu einer merklichen und/oder relevanten Beeinträchtigung oder Schädigung des jeweiligen Produktes nicht führt. Das sauerstofffreie oder im Wesentlichen sauerstofffreie Prozessgas enthält dann hauptsächlich Stickstoff sowie eventuell weiter Bestandteile, wie geringe Mengen an Argon, Kohlendioxid und Wasserdampf."Oxygen-free or substantially oxygen-free process gas" in the sense of the invention is a gas which contains at least one component obtained by fractionation of ambient or atmospheric air, which does not contain oxygen (O 2 , also O or O 3 ) or at most only such a small amount. contains negligible oxygen content, which does not lead to a significant and / or relevant impairment or damage to the respective product. The oxygen-free or substantially oxygen-free process gas then contains mainly nitrogen and possibly further constituents, such as small amounts of argon, carbon dioxide and water vapor.

"Fraktionierung von Umgebungs- oder Atmosphärenluft" bedeutet im Sinne der Erfindung die Trennung der Umgebungs- oder Atmosphärenluft in ihre Gas- und Dampf-Komponenten durch Verwendung wenigstens eines Gasfilters, vorzugsweise durch Verwendung wenigstens eines Membranfilters."Fractionation of ambient or atmospheric air" in the sense of the invention means the separation of the ambient or atmospheric air into its gas and vapor components by using at least one gas filter, preferably by using at least one membrane filter.

„Umgebungs- oder Atmosphärenluft" umfasst im Sinne der vorliegenden Erfindung neben der genannten Umgebungs- oder Atmosphärenluft auch ein sauerstofffreies oder im Wesentlichen sauerstofffreies Prozessgas, welches in einem Kreislaufverfahren mehrfach verwendet wird, und vor jeder Wiederverwendung erneut von eventuell auftretenden Sauerstoffverunreinigungen befreit wird.For the purposes of the present invention, "ambient or atmospheric air" includes, in addition to the ambient or atmospheric air mentioned, an oxygen-free or substantially oxygen-free process gas which is used repeatedly in a circulation process and is freed again from any occurring oxygen contaminants before each reuse.

Membranfilters.Membrane filter.

Die in der Figur 1 allgemein mit 1 bezeichnete Filteranlage dient zur Fraktionierung der aus einem Gemisch unterschiedlicher Gas-Komponenten bestehenden Umgebungsluft in die einzelnen Gas- und/oder Dampfbestandteile, die an den Ausgängen G1 - Gx der Filteranlage 1 jeweils gesondert bereitgestellt werden. Die Filteranlage besteht hierfür aus einem Gasfilter 2, in welchem die Fraktionierung durch entsprechende Filtermedien erfolgt. Die Filtermedien des Gasfilters 2 sind z.B. so ausgebildet und innerhalb eines oder mehrerer Strömungskanäle des Gasfilters 2 so angeordnet, dass an jedem Ausgang jeweils nur eine Gaskomponente erhalten wird. Der Gasfilter 2 ist bevorzugt als Membranfilter ausgebildet, bei dem die einzelnen Filtermedien z.B. von Filtermembranen gebildet sind, die jeweils nur für die dem jeweiligen Ausgang G1 - Gx zugeordnete Gaskomponente durchlässig ist. Dem Gasfilter 2 ist beispielsweise ein Sterilfilter 3 vorgeschaltet, über welches dem Gasfilter 2 die Umgebungsluft zugeführt wird und in welchem in der Umgebungsluft enthaltene Partikel, wie Staub, Ruß usw. aber auch insbesondere Keime und Mikroorganismen jeglicher Art, wie z.B. Pilze, Bakterien, Viren usw. zurückgehalten werden, sodass dem Gasfilter 2 nur saubere und sterile Umgebungsluft zugeführt wird und demnach auch an den Ausgängen G1 - Gx saubere und sterile Gaskomponenten zur Verfügung stehen.The filter system, generally designated 1 in FIG. 1, serves to fractionate the ambient air consisting of a mixture of different gas components into the individual gas and / or vapor constituents, which are provided separately at the outputs G1-Gx of the filter system 1, respectively. The filter system consists of a gas filter 2, in which the fractionation done by appropriate filter media. The filter media of the gas filter 2 are, for example, designed and arranged within one or more flow channels of the gas filter 2 such that only one gas component is obtained at each outlet. The gas filter 2 is preferably designed as a membrane filter, in which the individual filter media are formed, for example, by filter membranes which are permeable in each case only to the gas component assigned to the respective output G1-Gx. The gas filter 2 is preceded by a sterile filter 3, for example, via which the ambient air is supplied to the gas filter 2 and in which particles contained in the ambient air, such as dust, soot, etc. but also in particular germs and microorganisms of any kind, such as fungi, bacteria, viruses etc. are retained, so that the gas filter 2 only clean and sterile ambient air is supplied and therefore also at the outputs G1 - Gx clean and sterile gas components are available.

Die Filteranlage 1 ist zur Verwendung bei Behälterbehandlungsmaschinen oder - anlagen bestimmt und dabei insbesondere auch für solche Anlagen, die zur Verarbeitung, d.h. insbesondere zum Abfüllen von sauerstoffempfindlichen Produkten dienen.The filter system 1 is intended for use in container treatment machines or systems, and in particular also for those systems which are suitable for processing, i. especially for filling oxygen-sensitive products.

Mit der Filteranlage 1 ist es nun möglich, die für das jeweils zu verarbeitende Produkt nicht schädlichen, an den Ausgängen G1 - Gx bereitstehenden Komponenten, d.h. beispielsweise sämtliche Komponenten ausgenommen die Sauerstoffkomponente( O, 02, 03) als Prozessgas für die das betreffende Produkt verarbeitende Anlage 4 zu verwenden. Die entsprechenden Gaskomponeπten der Ausgänge G1 - Gx werden dann beispielsweise zusammengeführt und an die Anlage 4 geleitet. Die an einem oder aber an mehreren Ausgängen anfallende Sauerstoffkomponente wird z.B. in die Umgebung abgeleitet oder aber beispielsweise einer Anlage 5 zugeführt, in der unter Verwendung des Sauerstoffs Ozon oder ein ozonhaltiges Luft- und/oder Gasgemisch z.B. für Reinigungs- oder Sterilisationszwecke erzeugt.With the filter unit 1 it is now possible to obtain the components which are not harmful to the respective product to be processed and which are available at the outputs G1-Gx, i. For example, to use all components except the oxygen component (O, 02, 03) as the process gas for the plant 4 processing the product in question. The corresponding Gaskomponeπten the outputs G1 - Gx are then merged, for example, and passed to the system 4. The oxygen component produced at one or more outputs is e.g. derived in the environment or, for example, fed to a plant 5, in which using the oxygen ozone or an ozone-containing air and / or gas mixture, for. generated for cleaning or sterilization purposes.

Das vom Gasfilter 2 gelieferte sauerstofffreie Prozessgas dient in der Anlage 4 beispielsweise als Schutzgas beim Füllen von Behältern mit dem sauerstoffempfindlichen Produkt oder Füllgut und beim Verschließen dieser Behälter. Als Beispiel hierfür ist in der Figur 2 eine Verschließmaschine 6 umlaufender Bauart zum Verschließen von mit dem sauerstoffempfindlichen Produkt gefüllten Flaschen 7 dargestellt. Die Flaschen 7 werden für das Verschließen einem um eine vertikale Maschinenachse VA umlaufend angetriebenen Rotor 8 so zugeführt, dass jede Flasche aufrechtstehend auf einem Flaschenteller 9 des Rotor 8 unterhalb eines ebenfalls am Rotor vorgesehenen Verschließwerkzeugs 10 angeordnet ist, welches zum Verschließen der Flaschen 7 mit Kronenkorken oder anderen Verschlüssen ausgebildet ist. Zumindest mit einem die Flaschen- oder Behältermündung aufweisenden Flaschenhals sind die Flaschen 7 jeweils in einem von einer Einhausung 11 gebildeten, zur Umgebung hin getrennten Raum 12 aufgenommen, dem über Anschlüsse 13 das von dem Gasfilter 2 erzeugte Prozessgas zugeführt wird, und zwar derart, dass dieses Prozessgas den Innenraum 12 von oben nach unten durchströmt und im unteren Bereich des Raumes 12 in die Atmosphäre austritt. Der gesamte Innenraum 12 ist so von dem sauerstofffreien Prozessgas ausgefüllt und durchströmt. Auch die Mündungsöffnungen der Flaschen 7 werden intensiv von diesem Prozessgas umströmt.The oxygen-free process gas supplied by the gas filter 2 is used in the system 4, for example, as a protective gas when filling containers with the oxygen-sensitive product or product and when closing these containers. As an example of this, FIG. 2 shows a capping machine 6 of circumferential design for closing bottles 7 filled with the oxygen-sensitive product. For closing, the bottles 7 are supplied to a rotor 8 which is driven in rotation around a vertical machine axis VA such that each bottle is arranged upright on a bottle plate 9 of the rotor 8 below a closing tool 10 also provided on the rotor, which is used to close the bottles 7 with crown corks or other closures is formed. At least with a bottleneck having the bottle or container mouth, the bottles 7 are each accommodated in a space 12 formed by an enclosure 11 and separated from the environment, to which the process gas produced by the gas filter 2 is supplied via connections 13 in such a way that this process gas flows through the interior 12 from top to bottom and exits in the lower region of the space 12 into the atmosphere. The entire inner space 12 is filled and flowed through by the oxygen-free process gas. The mouth openings of the bottles 7 are intensively flowed around by this process gas.

In ähnlicher Weise sind die Flaschen 7 beim Füllen mit dem sauerstoffempfindlichen Produkt, d.h. in der der Verschließmaschine 6 in der Anlage 4 vorausgehenden Verschließmaschine sowie auch auf der Transportstrecke zwischen der Füllmaschine und der Verschließmaschine 6 ständig in der von dem Prozessgas des Gasfilters 2 gebildeten Schutzgasatmosphäre angeordnet.Similarly, the bottles 7 when filling with the oxygen-sensitive product, ie in the closing machine 6 in Appendix 4 preceding Sealing machine as well as on the transport route between the filling machine and the capping 6 constantly arranged in the formed by the process gas of the gas filter 2 inert gas atmosphere.

Erfolgt beim Füllen der Flaschen 7 vor dem Einbringen des Füllgutes ein Spülen des jeweiligen Flascheninnenraumes zur Verdrängung von Luft bzw. des entsprechenden Sauerstoffanteils, so kann dieses Spülen ebenfalls mit dem sauerstofffreien, von dem Gasfilter 2 gelieferten Prozessgas erfolgen. Bei einem kohlensäurefreien Füllgut, welches in die mit einem Gas vorgespannten Behälter oder Flaschen 7 abgefüllt wird, kann das von dem Gasfilter 2 gelieferte sauerstofffreie Prozessgas auch zum Druck- Vorspannen verwendet werden.If, during the filling of the bottles 7, a rinsing of the respective bottle interior takes place before the introduction of the contents to displace air or the corresponding oxygen content, then this rinsing can likewise be carried out with the oxygen-free process gas supplied by the gas filter 2. In the case of a non-carbonated filling material, which is filled into the gas-preloaded container or bottles 7, the oxygen-free process gas supplied by the gas filter 2 can also be used for pressure-tempering.

Die Figur 3 zeigt in einer Darstellung wie Figur 1 eine Filteranlage 1a, die sich von der Filteranlage im Wesentlichen nur dadurch unterscheidet, dass das Sterilfilter 3 dem Gasfilter 2 zum Fraktionieren der Umgebungsluft nachgeschaltet ist, und zwar derart, dass lediglich die als Prozessgas in der Anlage 4 verwendeten Komponenten der fraktionierten Luft in dem Sterilfilter behandelt werden, wodurch u.a. das im Sterilfilter zu verarbeitende Gasvolumen deutlich reduziert werden kann.FIG. 3 shows, in a depiction as in FIG. 1, a filter system 1a that differs essentially from the filter system only in that the sterile filter 3 is connected downstream of the gas filter 2 for fractionating the ambient air, in such a way that only the process gas in the Appendix 4 used fractionated air components are treated in the sterile filter, whereby, inter alia the volume of gas to be processed in the sterile filter can be significantly reduced.

Die Figur 4 zeigt in stark vereinfachter Funktions-Darstellung den Aufbau eines Gasfilters 2a. Dem Innenraum 14 dieses Gasfilters wird über einen Einlass 15 Umgebungsluft, beispielsweise zuvor in dem Sterilfilter 3 gereinigte Umgebungsluft zugeführt, und zwar z.B. über ein Gebläse. Im Innenraum 14 sind in Strömungsrichtung aufeinanderfolgend mehrere Filtermembranen 16 vorgesehen. Diese sind hinsichtlich ihrer Filterwirkung derart ausgewählt, dass an jeder Filtermembrane 16 eine Gaskomponente zurückgehalten und die verbleibenden Gaskomponenten weitergeleitet werden. Die zurückgehaltenen Gaskomponenten stehen dann an den den Filtermembranen zugeordneten Ausgängen G1 - Gx zur Verfügung.FIG. 4 shows the structure of a gas filter 2a in a greatly simplified functional representation. The interior 14 of this gas filter is supplied via an inlet 15 ambient air, for example, previously purified in the sterile filter 3 ambient air, namely. over a fan. In the interior 14, a plurality of filter membranes 16 are successively provided in the flow direction. These are selected with regard to their filtering effect such that a gas component is retained on each filter membrane 16 and the remaining gas components are passed on. The retained gas components are then available at the outputs G1-Gx associated with the filter membranes.

Die Erfindung wurde voranstehend an Ausführungsbeispielen beschrieben. Es versteht sich, dass zahlreiche Änderungen sowie Abwandlungen möglich sind, ohne dass dadurch der der Erfindung zugrunde liegende Erfindungsgedanke verlassen wird.The invention has been described above by means of exemplary embodiments. It is understood that numerous changes and modifications are possible without thereby departing from the inventive concept underlying the invention.

Vorstehend wurde davon ausgegangen, dass für jede aus der Umgebungsluft durch Fraktionieren gebildete Gaskomponente ein gesonderter Ausgang GI - Gx vorgesehen ist. Grundsätzlich besteht aber auch die Möglichkeit, das jeweilige Gasfilter so auszubilden, dass es für wenigstens zwei sauerstofffreie Komponenten einen gemeinsamen Ausgang aufweist. In jedem Fall ist aber das Gasfilter so ausgebildet, dass das von diesem Filter gelieferte und bei der Verarbeitung des sauerstoffempfindlichen Produktes, z.B. beim Füllen dieses Produktes und/oder beim Behandeln der verwendeten Packmittel genutzte Prozessgas sauerstofffrei ist.It has been assumed above that a separate output GI-Gx is provided for each gas component formed by fractionation from the ambient air. In principle, however, it is also possible to design the respective gas filter in such a way that it has a common output for at least two oxygen-free components. In any case, however, the gas filter is designed so that the product supplied by this filter and processed during the processing of the oxygen-sensitive product, e.g. used in filling this product and / or in treating the used packaging process gas is free of oxygen.

Weiterhin erstreckt sich der Umfang der vorliegenden Erfindung auch auf eine Anlage zur Abfüllung von Getränken, bei welcher zumindest eine Verschließmaschine und/oder eine Füllmaschine und/oder die Behältertraπsportwege zwischen diesen Maschinen vor der Umgebungsluft zumindest teilweise geschützt sind und zumindest teilweise mit sauerstofffreiem oder im Wesentlichen sauerstofffreiem Prozessgas beaufschlagt werden. Durch die technische Lehre der vorliegenden Erfindung wird, u.a. durch die erhebliche Senkung der Kosten für die Gestehung eines sauerstofffreien oder im Wesentlichen sauerstofffreien Prozessgases, dieses im sehr viel größerem Umfang einzusetzen, als bisher, was eine weitere Reduzierung des Sauerstoffgehalts im den Verpackten und/oder abgefüllten Produkten ermöglicht. Furthermore, the scope of the present invention also extends to a plant for bottling beverages, in which at least one closing machine and / or a filling machine and / or the Behältertraπsportwege between these machines from the ambient air are at least partially protected and at least partially with oxygen-free or substantially oxygen-free process gas are applied. The technical teaching of the present invention, inter alia, by the significant reduction in the cost of the supply of an oxygen-free or substantially oxygen-free process gas to use this to a much greater extent than before, resulting in a further reduction of the oxygen content in the packaged and / or bottled products.
