Description
Die Erfindung betritt ein Verfahren und eine Vorrichtung zur Sterilisation mit Heißluft. The invention relates to a method and apparatus for sterilization with hot air.
Es sind bereits Verfahren und Vorrichtungen zur Sterilisation mit ffeißluft bekannt, bei denen die im Entkeimungsraum befindliche Luft durch ein Gebläse im Umlauf und durch eine regulierbare Heizung auf ether bestimmten Temperatur gehalten wird, das Gebläse und die Heizung außerhalb des Sterilisationsraumes angebracht sind und der Umlauf der Luft über einen Luftzuführungs- und einen Luftabführungskanal erfolgt (vgl. Patentschriften 306 610, 534 574 und 698658). There are already methods and devices for sterilization with ffeißluft known, in which the air in the sterilization room is blown by a fan in circulation and kept at a certain temperature by an adjustable heater is installed, the fan and the heater outside of the sterilization room and the circulation of the air via an air supply and an air discharge duct takes place (see patents 306 610, 534 574 and 698658).
Es wurde nun gefunden, daß die Sterilisationswirkung bei Verfahren und Vorrichtungen der vorerwähnten Art verbessert werden kann, wenn man die Gleichmäßigkeit des durch den Sterilisationsraum hindurchfließenden Luftstromes dadurch fördert, daß man im Luftabzugskanal einen Unterdruck erzeugt, durch den die Luft aus dem Sterilisationsraum möglichst gleichmäßig abgezogen wird. Der Unterdruck im Luftabzugskanal unterstützt den Überdruck im Luftzuführungskanal dahingehen, daß der Luftstrom möglichst gleichmäßig und ohne Stauungen den Sterilisatonsram und das darin befindliche Gut durchdringt. It has now been found that the sterilization effect in procedures and devices of the aforementioned type can be improved if the uniformity the air flow flowing through the sterilization room that one creates a negative pressure in the air outlet duct, through which the air from the The sterilization room is drawn off as evenly as possible. The negative pressure in the air exhaust duct supports the overpressure in the air supply duct to the effect that the air flow as possible Evenly and without congestion the Sterilisatonsram and the goods in it penetrates.
Eine technisch einfache Ausführungsform des Erfindungsgedankens ist in der Zeichnung dargestellt. Wenn man nämlich einen Teil der umlaufenden Luft nicht in den Sterilisationsraum ein führt, sondern um den ganzen Sterilisationskasten herumführt und dann in den Luftabzugskanal gelangen läßt, erzeugt dieser Teilluftstrom im Luftabzugskanal eine Saugwirkung, die das Abziehen der Luft aus dem Sterilisationsraum wirkungsvoll unterstützt. A technically simple embodiment of the inventive concept is shown in the drawing. If you can't get some of the circulating air leads into the sterilization room, but around the entire sterilization box leads around and then lets get into the air exhaust duct, this generates partial air flow a suction effect in the air exhaust duct, which draws the air out of the sterilization room effectively supported.
Gemäß der Erfindung können aucll die wirderstandsfähigsten Keime bei Temperaturen von z. r. According to the invention, the most resistant germs can also be used at temperatures of e.g. r.
