Description
Verwendung von PhosPhorsäure und VerfahrenUse of Phosphoric Acid and Process
zum Sterilisieren von Terpackungsmaterial Stand der Technik Zum Sterilisieren von Packstoffen und Packmitteln wird heute in der Praxis überwiegend Wasserstoffperoxid eingesetzt. Obwohl die Entkeimungswirkung von Wasserstoffperoxid zufriedenstellend ist, bestehen die Probleme, daß allenfalls in der Packung verbleibende Rückstände Fremdstoffe sind, die einer Reglementierung unterliegen, und daß aus den verwendeten wässrigen Wasserstoffperoxidlösungen auch Wasserstoffperoxiddämpfe entweichen, die für die Maschinenbedienungspersonen Grund für eine Belästigung sind, wie Reizung der Schleimhäute und Bleichung der Haare.for the sterilization of packaging material State of the art For sterilization of packaging materials and packaging materials is predominantly hydrogen peroxide in practice today used. Although the disinfecting effect of hydrogen peroxide is satisfactory is, there are the problems that at most residues remaining in the pack Foreign substances are subject to regulation, and that from the used aqueous hydrogen peroxide solutions also escape the hydrogen peroxide vapors cause nuisance to machine operators, such as irritation of the mucous membranes and bleaching of the hair.
Es ist daher ein ähnlich wirkendes Mittel erstrebenswert, welches die geschilderten Nachteile nicht aufweist. Das gesuchte Mittel sollte geruchsneutral, bei Anwendungsbedingungen nicht als Dampf belästigen und kein 1>ebensmittelfremdstoff sein.It is therefore worth striving for a means with a similar effect, which does not have the disadvantages described. The agent you are looking for should be odorless, Do not annoy as steam under conditions of use and no 1> food foreign substance be.
Bei Bacillus subtilis - Sporen ergaben a) 40prozentige Phosphorsäure D = 9 sec bei 70 °C D = 2,5 sec " 80 °C b) 60prozentige Phosphorsäure D = 22 sec bei 60 0 D = 6 sec bei 70 0 c) 85prozentige Phosphorsäure D = 6 sec bei 30 0 D = 0,6 sec bei 41 °C Bei Bacillus stearothermophilus - Sporen wurden mit d) 85prozentiger Phosphorsäure die folgenden D-Werte ermittelt: D = 13 sec bei 40 OC D = 1,3 sec bei 54 °C.Bacillus subtilis spores gave a) 40 percent phosphoric acid D = 9 sec at 70 ° C D = 2.5 sec "80 ° C b) 60 percent phosphoric acid D = 22 sec at 60 0 D = 6 sec at 70 0 c) 85 percent phosphoric acid D = 6 sec at 30 0 D = 0.6 sec at 41 ° C. In Bacillus stearothermophilus - spores were 85 percent higher with d) Phosphoric acid determined the following D values: D = 13 sec at 40 ° C. D = 1.3 sec at 54 ° C.
Zum Entkeimen von Packstoffen, wie Kunststoffbahnen, kunststoffbeschichtete Kartonbahnen werden 4 bis 6 D für Bacillus subtilis gefordert. Das ergäbe unter Verwendung einer 40prozentigen Ortho-Phosphorsäure bei einer Behandlungstemperatur von 80 °C eine Behandlungsdauer von 10 bis 15 sec. Bei niedrigerer Temperatur genügen ähnliche Zeiten, wenn die Eonzentration höher gewählt wird. In der Konserventechnik fordert man für Bacillus stearothermophilus nur ein 2 D - Konzept.For disinfecting packaging materials such as plastic sheets, plastic-coated Cardboard sheets of 4 to 6 D are required for Bacillus subtilis. That would result in Use of a 40 percent orthophosphoric acid at a treatment temperature from 80 ° C a treatment time of 10 to 15 seconds. At a lower temperature, sufficient similar times if the concentration is chosen higher. In canning technology only a 2D concept is required for Bacillus stearothermophilus.
Vorteile der Erfindung Beim Sterilisieren von Verpackungsmaterial mit Phosphorsäure wird die oben gestellte Aufgabe erfüllt. Ihre Verwendung hat außerdem die Vorteile, daß sie eine überraschend hohe keimtötende Wirkung hat, geruchlos ist und in wässriger Lösung erst bei Temperaturen über dem Anwendungsbereich verdampft. Es kommt ferner hinzu, daß Phosphorsäure als Lebensmittelsäure gilt, d.h., daß diese in Lebensmitteln enthalten ist oder zugesetzt werden darf 1 beispielsweise bei coffeinhaltigen Limonaden bis zu einer Konzentration von 0,7 %.Advantages of the Invention When sterilizing packaging material With phosphoric acid, the above task is achieved. Their use also has the advantages of having a surprisingly high germicidal effect, odorless and only evaporates in aqueous solution at temperatures above the application range. It should also be added that phosphoric acid is considered a food acid, i.e. that this is contained in food or may be added 1 for example with caffeine Lemonades up to a concentration of 0.7%.
Laborversuche Die keimtötende Wirkung von Phosphorsäure wurde an Sporen von Bacillus subtilis und Bacillus stearothermophilus labormäßig ermittelt. Bacillus subtilis wurde ausgewählt, da dieser üblicherweise als Testkeim für die Wasserstoffperoxidentkeimung genommen wird. Bacillus stearothermophilus gilt als die hitzebeständigste Mikrobenart. Es wurden Versuche mit 40-, 60- und 85prozentiger Ortho-Phosphorsäure bei.verschiedenen Temperaturen durchgeführt. Dabei wurden die D-Werte ermittelt, welche die Zeit in Sekunden für die Reduzierung der Keimzahl auf 10 % der jeweiligen Ausgangskeimzahl angeben.Laboratory experiments The germicidal effect of phosphoric acid was on spores of Bacillus subtilis and Bacillus stearothermophilus determined in the laboratory. Bacillus subtilis was chosen because it is usually used as a test germ for hydrogen peroxide germination is taken. Bacillus stearothermophilus is considered to be the most heat-resistant type of microbe. There were experiments with 40, 60 and 85 percent orthophosphoric acid at.vifferenen Temperatures carried out. The D-values were determined, which correspond to the time in Seconds for the reduction of the germ count to 10% of the respective initial germ count indicate.
Für wenig verkeimte Packstoffe reicht daher weniger, z.B. das 1 D - Konzept, was bedeutet, daß bei Verwendung 40prozentiger Ortho-Phosphorsäure die Behandlungsdauer 13 sec bei 40 0C und 1,5 sec bei 54 0C beträgt.Less is therefore sufficient for packaging materials with few germs, e.g. the 1 D - Concept, which means that when using 40 percent orthophosphoric acid the Treatment duration is 13 seconds at 40 ° C. and 1.5 seconds at 54 ° C.
Ausführunp;sbeispiele Zum Sterilisieren einer Packstoffbahn, aus der in keimfreier Umgebung fortlaufend Verpackungsbehältnisse geformt, diese mit sterilem Gut befüllt und verschlossen werden, wird die Packstoffbahn durch ein Bad aus Phosphorsäure gezogen. Die beim Austreten der Babn aus dem Bad mitgezogene Phosphorsäure in Form von Tröpfchen oder eines -Films wird mit Quetschwalzen, einem Luftschleier oder durch Absaugen am Eingang einer Sterilkammer einer Verpackungsmaschine entfernt. Die Parameter für Phosphorsäurekonzentration, Temperatur und Baddurchlaufzeit werden aufgrund von Versuchen ermittelt und eingestellt.Embodiments For sterilizing a packaging material web from which In a sterile environment continuously formed packaging containers, these with sterile The packaging material web is well filled and sealed by a bath of phosphoric acid drawn. The phosphoric acid drawn in when the baby emerges from the bath in the form of droplets or a film is made with nip rollers, an air curtain or removed by suction at the entrance of a sterile chamber of a packaging machine. The parameters for phosphoric acid concentration, temperature and bath cycle time are determined and adjusted on the basis of tests.
Bereits geformte Verpackungsbehältnisse werden, um sie allseitig zu entkeimen, in ein Phosphorsäurebad getaucht, wobei eine Fördereinrichtung diese nacheinander durch das Bad führt. Da es in den meisten Fällen genügt, nur die Innenseiten der Behältnisse zu entkeimen, können diese mit Phosphorsäure befüllt und wieder entleert werden, oder es kann Phosphorsäure auch auf deren Innenwandung versprüht werden. In allen Fällen ist ein nachfolgendes Spülen mit steriler Luft oder auch sterilem Wasser empfehlenswert, um die Rückstände klein zu halten.Packaging containers that have already been formed are used to cover them on all sides sterilize, immersed in a phosphoric acid bath, with a conveyor device this one after the other through the bathroom. Since it is sufficient in most cases, only the inside To sterilize the containers, they can filled with phosphoric acid and emptied again, or phosphoric acid can also be applied to the inner wall be sprayed. In all cases there is a subsequent flushing with sterile air or sterile water is recommended to keep the residues small.
Je nach der verwendeten Konzentration der Phosphorsäure sind Behandlungszeiten von 10 bis 20 sec bei beherrschbaren Arbeitstemperaturen von 30 bis 80 °C hinnehmbar.Treatment times depend on the concentration of phosphoric acid used from 10 to 20 seconds at a controllable working temperature of 30 to 80 ° C.
