Description

Verfahren zum Verpacken von verderblichem Verpackungsgut Process for packaging perishable goods
Die Erfindung bezieht sich auf ein Verfahren zum Verpacken von verderblichem Verpackungsgut, bei dem ein Folienschlauch nach dem Füllen an mindestens einem offenen Ende zu einem Zopf zusammengerafft, der Zopf daraufhin mit einem Clip verschlossen und das Verpackungsgut anschließend sterilisiert wird.The invention relates to a method for packaging perishable packaged goods, in which a film tube is gathered into a braid after filling at least one open end, the braid is then closed with a clip and the packaged goods are then sterilized.
Es ist heute üblich, haltbare Kochwürste, nämlich Leber- und Blutwürste, aber auch Tier- und Babynahrung in einen Kunststoffdarm zu füllen, dessen Enden nach dem Füllen zu einem Zopf zusammengerafft und mit Clips verschlossen werden, worauf das Verpackungsgut in der geschlossenen Folienschlauchverpackung in einem Autoklaven gekocht und dadurch sterilisiert wird. Dies geschieht mit dem Ziel, eine möglichst lange, ungekühlte Haltbarkeit des Verpackungsgutes zu erreichen. Erfahrungsgemäß verderben aber etwa 10% des auf die beschriebene Art und Weise verpackten Verpackungsgutes vorzeitig, weil beispielsweise Bakterien durch den Zopf in das Innere der Verpackung eindringen. Der Erfindung liegt die Aufgabe zugrunde, das Verderben von Verpackungsgut in einer Folienschlauchverpackung zuverlässiger als bisher zu unterbinden.It is common today to fill long-life cooked sausages, namely liver and blood sausages, but also animal and baby food, into a plastic casing, the ends of which are gathered into a braid after filling and closed with clips, whereupon the packaged goods in the closed tubular film packaging in one Autoclave is boiled and thereby sterilized. This is done with the aim of achieving the longest possible, uncooled shelf life of the packaged goods. Experience has shown, however, that around 10% of the packaging goods packaged in the manner described spoil prematurely because, for example, bacteria penetrate the inside of the packaging through the braid. The invention has for its object to prevent the spoilage of packaged goods in a tubular film packaging more reliably than before.
Die Lösung dieser Aufgabe besteht erfindungsgemäß in einem Verfahren der eingangs genannten Art, bei dem das Zopfende nach dem Sterilisieren mit hei߬ flüssiger Dichtungsmasse von mindestens 1 20° C abgedichtet wird.This object is achieved, according to the invention, in a method of the type mentioned at the outset, in which the end of the braid is sealed with hot-liquid sealant of at least 120 ° C. after sterilization.
Der Kern der Erfindung besteht darin, daß das erfindungsgemäße Abdichten auch nach dem Abkühlen der sterilisierten Verpackung erfolgen kann, weil eventuell in den Folienzopf eingedrungene Bakterien durch die mindestens 1 20° C heiße Dichtungsmasse abgetötet werden. Schrumpfungsvorgänge des Folienmaterials während des Sterilisierens und des Abkühlens können die Abdichtung nicht beein¬ trächtigen. Außerdem ist die nach dem erfindungsgemäßen Verfahren hergestellte Verpackung auch deshalb besonders dicht, weil beim Sterilisieren Fette und Öle aus dem Zopfinneren ausgewaschen werden, so daß sich die Haftung der Dich¬ tungsmasse an dem Zopf deutlich verbessert, wenn sie nicht durch das Sterilisieren überhaupt erst ermöglicht wird.The essence of the invention is that the sealing according to the invention can also be carried out after the sterilized packaging has cooled, because bacteria which may have penetrated into the film braid are killed by the sealing compound which is at least 1 20 ° C. Shrinking processes of the film material during sterilization and cooling cannot impair the sealing. In addition, the packaging produced by the method according to the invention is also particularly leakproof because fats and oils are washed out of the inside of the braid during sterilization, so that the adhesion of the sealing compound to the braid is significantly improved if it is not made possible by sterilization in the first place becomes.
Es ist zwar aus der DE-PS 40 1 9 937 und der DE-OS 35 00 625 bekannt, das jeweils freie Ende eines jeden mit einem Clip verschlossenen Folienschlauch-Zopfes mit Dichtuπgsmasse zu versiegeln. Auf diese Weise soll unter anderem ein Ein¬ dringen von Sauerstoff und Feuchtigkeit sowie von Bakterien und Pilzen verhindert werden. Dies gelingt aber bei zu sterilisierenden, gefüllten Verpackungen nicht ohne weiteres: Falls die Versiegelung schon vor oder unmittelbar nach dem Sterili¬ sieren auf das Verpackungsende aufgebracht werden würde, käme es infolge des Schrumpfens des Folienschlauches während des Abkühlens nach dem Sterilisieren zu Undichtigkeiten, weil sich der schrumpfende Folienschlauch von der Dichtungs¬ masse löst. Würde die Verpackung dagegen erst nach dem Abkühlen versiegelt, besteht die Gefahr, daß die sich beim Abkühlen kontrahierende Verpackung durch den noch unversiegelten Folienzopf Bakterien z.B. aus dem Kühlwasser aufnimmt.It is known from DE-PS 40 1 9 937 and DE-OS 35 00 625 to seal the free end of each film tube braid closed with a clip with sealing compound. In this way, penetration of oxygen and moisture, as well as bacteria and fungi, is to be prevented. However, this does not easily succeed in the case of filled packaging to be sterilized: if the seal were applied to the end of the packaging before or immediately after sterilization, there would be leaks as a result of the shrinking of the film tube during cooling after sterilization because the shrinking film tube detaches from the sealing compound. If, on the other hand, the packaging was only sealed after cooling, there is a risk that the packaging, which contracts when cooling, may become bacteria, e.g. from the cooling water.
Eine bevorzugte Variante des erfindungsgemäßen Verfahrens besteht darin, daßder sterilisierte Zopf zum Abdichten für eine begrenzte Zeit in eine flüssige Dichtungs¬ masse eingetaucht wird und die nach dem Eintauchen an dem Zopf haftende Dichtungsmasse anschließend trocknen gelassen wird. Das Eintauchen des ab¬ zudichtenden Zopfes in die flüssige Dichtungsmasse kann die Dichtigkeit und Zuverlässigkeit des Zopfverschlusses noch einmal erhöhen. Während des Ein¬ tauchens kann die flüssige Dichtungsmasse besonders gut in Kapillaren des Ver- packungszopfes eindringen und diese verschließen. Eine Alternative zum Eintau¬ chen des sterilisierten Zopfes in die flüssige Dichtungsmasse besteht dann, die Dichtungsmasse mit einer Düse auf den Zopf aufzuspritzen.A preferred variant of the method according to the invention consists in immersing the sterilized braid in a liquid sealing compound for sealing for a limited time and then allowing the sealing compound adhering to the braid to dry after immersion. Immersing the braid to be sealed in the liquid sealing compound can further increase the tightness and reliability of the braid fastener. During the immersion, the liquid sealing compound can be particularly well in the capillaries of the penetrate the packing braid and close it. An alternative to immersing the sterilized braid in the liquid sealant is then to spray the sealant onto the braid using a nozzle.
Eine bevorzugte Weiterbildung des Verfahrens besteht dann, den Zopf so weit in die Dichtungsmasse einzutauchen, daß der Zopf und der Clip mit Dichtungsmasse benetzt sind. Indem auch der Clip von Dichtungsmasse umgeben ist, kann sich die Dichtungsmasse besonders gut an dem verschlossenen Zopfende verkrallen, so daß sie sich auch unter ungünstigen Umständen nicht von dem Zopfende löst.A preferred development of the method then consists of immersing the braid so far into the sealant that the braid and the clip are wetted with sealant. Since the clip is also surrounded by sealing compound, the sealing compound can claw particularly well at the closed end of the pigtail, so that it does not detach from the pigtail end even under unfavorable circumstances.
Als Dichtmasse geeignet sind Thermoplaste, die nach dem Abkühlen oder Aushär¬ ten elastisch bleiben. Auch Kleber, die durch Licht, Luft oder Wasser ausharten, können eingesetzt werden.Thermoplastics which remain elastic after cooling or hardening are suitable as sealing compound. Adhesives that harden through light, air or water can also be used.
Das erfindungsgemäße Verfahren sowie eine mit dem Verfahren hergestellte Verpackung sollen nun an Hand der Zeichnungsfigur erläutert werden. Sie zeigt ein verschlossenes Ende einer Folienschlauch-Verpackung nach dem erfindungsgemä¬ ßen Verpacken.The method according to the invention and a packaging produced with the method will now be explained with reference to the drawing figure. It shows a closed end of a film tube packaging after the packaging according to the invention.
Das Verfahren beginnt mit dem Befüllen eines Folienschlauches auf übliche Art und Weise: Ein Folienschlauch-Vorrat ist auf ein Füilrohr derart aufgezogen, daß sich sein eines Ende vor der Auslaßöffnung des Füllrohres befindet. Dieses Ende ist verschlossen. Indem nun Füllgut durch das Füllrohr gepreßt wird, gelangt das Füllgut in den Folienschlauch und füllt diesen bei dem verschlossenen Ende begin¬ nend auf. Mit zunehmender Füllmasse wird entsprechend Folienschlauch von dem Folienschlauch-Vorrat auf dem Füllrohr abgezogen. Wenn sich schließlich eine ausreichende Menge des Füllgutes in dem Folienschlauch vor der Füllrohrauslaßöff- nung befindet, wird der Folienschlauch unmittelbar vor dem Füllrohrauslaß in bekannter Weise von entsprechenden Werkzeugen zu einem Zopf zusammengerafft und mit einem Clip verschlossen.The process begins with the filling of a film tube in the usual way: a film tube supply is drawn onto a filling tube in such a way that one end is located in front of the outlet opening of the filling tube. This end is closed. Now that the filling material is pressed through the filling tube, the filling material enters the film tube and fills it up at the closed end. As the filling mass increases, the film tube is drawn off from the film tube supply on the filling tube. When there is finally a sufficient amount of the filling material in the film tube in front of the filling tube outlet opening, the foil tube is gathered together in a known manner by appropriate tools to form a braid immediately before the filling tube outlet and closed with a clip.
Anschließend wird die nunmehr an beiden Enden verschlossene und gefüllte Folienschlauch-Verpackung von dem übrigen Folienschlauch abgetrennt und kann sterilisiert werden. Beim Sterilisieren werden gleichzeitig die Zopfenden von an¬ haftendem Fett o.a. befreit. Dadurch werden das Sterilisieren und das Reinigen der verschlossenen Verpackungsenden zu einem Verfahrensschritt. Ein separates Reinigen ist nicht notwendig. In der Regel wird die gesamte Verpackung sterilisiert werden, indem sie auf über 1 20° C erhitzt und anschließend abgekühlt wird. Das Erhitzen erfolgt dabei in einem Autoklaven bei ca. 2,3 bar Innendruck. Nach dem Sterilisieren werden Verpackungsgut und Verpackung mit Kühlwasser abgekühlt.The film tube packaging, which is now closed and filled at both ends, is then separated from the rest of the film tube and can be sterilized. During sterilization, the ends of the braid are simultaneously freed of adhering fat or the like. This makes sterilizing and cleaning the sealed ends of the packaging a step in the process. A separate cleaning is not necessary. As a rule, the entire packaging will be sterilized by heating it to above 120 ° C and then cooling it. The It is heated in an autoclave at an internal pressure of approx. 2.3 bar. After sterilization, the packaged goods and packaging are cooled with cooling water.
Für die zu sterilisierenden Verpackungen wird ein Folienschlauch eingesetzt, der nach dem Sterilisieren stark schrumpft. Die Verpackung wird nach dem Kühlvor¬ gang sehr stramm, und der über den Clip hinausragende Zopf schrumpft um ca. 10 bis 20%. Der Folienzopf sollte aber möglichst nicht über den Clip hinausragen, um eine kompakte, kleine und materialsparende Abdichtung zu erreichen. Nach dem Sterilisieren wird jedes verschlossene Zopfende in flüssige Dichtungsmasse ge¬ taucht, so daß sowohl der Zopf als auch der Clip mit Dichtungsmasse benetzt werden. Die flüssige Dichtungsmasse hat dabei eine Temperatur von über 1 20°C und trägt dazu bei, daß jedes Verpackungsende noch einmal sterilisiert wird. Immerhin ist es ja möglich, daß ein Zopfende zwischen dem eigentlichen Sterilisie¬ ren und dem Abdichten, beispielsweise durch Kühlwasser, mit Bakterien in Berüh¬ rung kommt. Während des Abdichtens dringt die heiße, flüssige Dichtungsmasse in die Kapillaren des Zopfes ein und versiegelt diese.A film tube is used for the packaging to be sterilized, which shrinks considerably after sterilization. After the cooling process, the packaging becomes very tight and the braid protruding beyond the clip shrinks by approximately 10 to 20%. However, the foil braid should not protrude beyond the clip if possible in order to achieve a compact, small and material-saving seal. After sterilization, each closed end of the braid is immersed in liquid sealant, so that both the braid and the clip are wetted with sealant. The liquid sealant has a temperature of over 1 20 ° C and helps to ensure that each end of the packaging is sterilized again. After all, it is possible that a braid end comes into contact with bacteria between the actual sterilization and the sealing, for example by cooling water. During the sealing process, the hot, liquid sealant penetrates into the capillaries of the braid and seals them.
Anschließend wird die Dichtungsmasse trocknen gelassen. Da die Dichtungsmasse möglichst auch den Verschlußclip mit einschließt, ist sie schließlich praktisch unlösbar mit dem verschlossenen Zopfende verkrallt.The sealant is then left to dry. Since the sealant also includes the closure clip, if possible, it is ultimately practically inseparable from the closed end of the braid.
Es ergibt sich dann das in der Figur gezeigte Bild: Der mit einem Füllgut, z.B. Wurst, gefüllte Folienschlauch 10 ist an einem Ende zu einem Zopf 1 2 zusammen¬ gerafft und mit einem Clip 14 verschlossen. Der Clip 14 und der Zopf 1 2 sind dabei ganz von getrockneter Dichtungsmasse 1 6 eingeschlossen. Ein solcher Verschluß erlaubt, wenn die Verpackung nach dem erfindungsgemaßen Verfahren hergestellt wurde, eine dauerhafte Konservierung des Füllgutes über ein Jahr hinaus, ohne daß die Verpackung samt Füllgut gekühlt werden muß. The result is the image shown in the figure: The one with a filling, e.g. Sausage, filled film tube 10 is gathered together at one end to form a braid 12 and closed with a clip 14. The clip 14 and the braid 1 2 are completely enclosed by dried sealant 1 6. If the packaging was produced by the method according to the invention, such a closure allows the contents to be permanently preserved for more than a year without the packaging and the contents having to be cooled.
