An Stelle des gewöhnlich zur Anwendung kommenden Sterilisationsverfahrens, bei welchem die zu sterilisierende Flüssigkeit, z. B. Milch, in der Regel einer dicht bei ioo°C liegenden Temperatur während längerer Zeit ausgesetzt wird, hat man vielfach zur Beschleunigung des Sterilisationsvorganges vorgeschlagen, die Temperatur unter Abkürzung der Einwirkungsdauer zu erhöhen, wobei manInstead of the commonly used sterilization process in which the liquid to be sterilized, e.g. B. Milk, usually one close to 100 ° C is exposed to a lying temperature for a long time, one has to accelerate in many cases of the sterilization process suggested, the temperature under abbreviation to increase the exposure time, whereby one
ίο bei einer Einwirkungsdauer von wenigen Sekunden auf Temperaturen von weit über ioo° gelangt ist. Die Verwendung einer höheren Temperatur war hierbei deswegen geboten, weil sonst bei der kurzen Einwirkungszeit eine sichere Abtötung der Mikroorganismen nicht erreicht werden konnte. Die vorerwähnten gewöhnlichen und auch das zuletzt erläuterte Sterilisationsverfahren haben aber gemeinsam den Nachteil, daß mit ihrer Anwendung eine wesentliche Veränderung der zu sterilisierenden Flüssigkeit hinsichtlich ihrer natürlichen Eigenschaften verbunden ist. So gehen bei Milch die biologischen Eigenschaften, die bei Rohmilch vorhanden sind und die gerade bei der Milch neben der Wirkung als Nährmittel im Interesse ihrer Bekömmlichkeit und Heilwirkung nach neueren Forschungen von großer Bedeutung sind, vollständig verloren. Ähnlich ist es bei vielen anderen Flüssigkeiten. Bei Blut, Serum, Hämatogen usw. veranlaßt die Einwirkung der Sterilisationstemperatur eine Denaturierung des-Eiweißes, so daß das Serum zersetzt und verdorben wird. Bei Trinkwasser tritt eine mehr oder,.weniger starke Zersetzung und Veränderung der darin enthaltenen Salze ein, so daß ein sterilisiertes Wasser dem natürlichen nicht mehr gleichkommt. Insbesondere werden alle Bikarbonate und die in den Wassern vorkommenden gebundenen Gase zersetzt und ausgetrieben, was z. B. bei Mineralwässern höchst unerwünscht ist.ίο with an exposure time of a few seconds has reached temperatures of well over 100 °. The use of a higher Temperature was required here because otherwise the short exposure time would cause a safe killing of the microorganisms could not be achieved. The aforementioned However, the usual and the last-mentioned sterilization process have in common the disadvantage that with their use a significant change in the sterilized Liquid in terms of its natural properties. So go at Milk the biological properties that are present in raw milk and that are currently used in of milk in addition to its effect as a nutrient in the interests of its digestibility and medicinal properties according to recent research are of great importance, completely lost. Similar it is with many other liquids. In the case of blood, serum, hematogen, etc., the cause The effect of the sterilization temperature denatures the protein, so that the serum decomposed and spoiled. In the case of drinking water, there is more or less severe decomposition and changing the salts contained therein, so that a sterilized water corresponds to the natural one no longer equals. In particular, all bicarbonates and those in the Bound gases occurring in water decomposed and expelled, which z. B. with mineral waters is highly undesirable.
Bei dem den Gegenstand der vorliegenden Erfindung bildenden Verfahren, welches ebenfalls den Schnellsterilisationsverfahren zugerechnet werden mniß, wird dieser Nachteil dadurch vermieden, daß die zu sterilisierende Flüssigkeit zunächst unter starken Druck gesetzt und dann unter plötzlicher Druckentlastung ebenso schnell auf die Sterilisationstemperatur erwärmt wird, worauf nach Ein- halten dieser Sterilisationstemperatur während einer sehr kurzen Zeit in bekannter Weise zweckmäßig plötzlich abgekühlt wird.In the method forming the subject of the present invention, which also must be added to the rapid sterilization process, this disadvantage becomes avoided that the liquid to be sterilized is initially placed under strong pressure and is then just as quickly heated to the sterilization temperature with sudden pressure relief, whereupon after activation maintain this sterilization temperature for a very short time in a known manner is expediently suddenly cooled.
Es ist an sich bekannt, daß ein plötzlicher Druckwechsel auf die in Flüssigkeiten vorhandenen Mikroorganismen hinsichtlich ihrer Lebensfähigkeit stark schwächend wirkt, und zwar um so stärker, je intensiver und plötzlicher der Druckwechsel stattfindet. Durch die Ausnutzung dieser an sich bekannten Erkenntnis bei der Sterilisation von Flüssigkeiten wird die Möglichkeit gegeben, bei sehr kurzer Einwirkungszeit eine relativ geringe und in der Regel unter 100 ° C liegende Sterilisationstemperatur zu verwenden, wobei der Sterilisationseffekt durch die Plötzlichkeit, mit der die Temperaturerhöhung einsetzt, günstig unterstützt wird. Da infolge des vorauf gegangenenIt is known that a sudden change in pressure on the existing in liquids Microorganisms has a strong weakening effect on their viability, namely the stronger, the more intense and sudden the pressure change takes place. By taking advantage of this knowledge, which is known per se the sterilization of liquids offers the possibility of a very short exposure time a relatively low and usually below 100 ° C sterilization temperature to use, the sterilization effect due to the suddenness with which the Temperature increase begins, is favorably supported. As a result of the previous one
