Abstract

Sterilization of plastic bottles using microwave plasma comprises introduction of the bottles into a vacuum container made of metal and production of plasma by means of a plasma head. Sterilization of plastic bottles using microwave plasma comprises introduction of the bottles into a vacuum container made of metal and production of plasma by means of a plasma head. When the bottles are to be sterilized externally and internally, the plasma pressure is periodically pulsed to introduce the active medium into the bottle interior. When only internal sterilization is required, the bottles are closed by a special unit ensuring that plasma burns only the bottle interior.

Description

Zwecks Desinfektion werden Kunstoffflaschen vorteilhaft mit einem Niederdruck- Mikrowellenplasma behandelt. Es ist einfacher und preiswerter als eine Spülung mit Chemikalien, wie z. B. Wasserstoffperoxid das anschließend eine Trocknung benötigt. For the purpose of disinfection, plastic bottles are advantageously Microwave plasma treated. It is easier and cheaper than using a conditioner Chemicals such as B. hydrogen peroxide then drying needed.

Es werden hier 2 Varianten die das Problem einfach lösen beschrieben. Two variants are described here that simply solve the problem.

1) Variante 1 - gleichzeitige Außen- und Innensterilisation1) Variant 1 - simultaneous external and internal sterilization

Sollen gleichzeitig innen und außen sterilisiert werden, vereinfacht sich das Verfahren erheblich: in einer metallischen Vakuumkammer (Abb. 1+2+3) wird die Mikrowellenleistung mittels unseres bereits beschriebenen "Plasmakopfs" (OS-DE 197 15 583 A1 bzw. DE 198 22 355 A1) auf einfachste Weise eingespeißt. Vorteilhaft ist eine Plasmadichteerhöhung mittels des dort beschriebenen Magnetkranzes. Eine oder auch eine Vielzahl von nicht verschlossenen Flaschen befinden sich in diesem Raum. If sterilization is to be carried out internally and externally at the same time, the procedure is considerably simplified: in a metallic vacuum chamber ( Fig. 1 + 2 + 3), the microwave power is achieved using our "plasma head" (OS-DE 197 15 583 A1 and DE 198 22, respectively) 355 A1) in the simplest way. A plasma density increase by means of the magnetic ring described there is advantageous. One or even a number of unsealed bottles are in this room.

Nach Evakuierung der störende Luft wird das oder die gewünschten Gase eingelassen Üblicher Arbeitsdruck 10 Pa. Aufgrund der besondere Eigenschaften der o. g. Einspeisung, die einem Druckbereich von 100 Pa bis, je nach Ausführung, 0,01 Pa für das Plasma zulässt, ist es möglich z. B. bei laufender Pumpe, durch periodisches Ein- und Ausschalten der Gaszufuhr den Druck in der Kammer zu variieren. Der Druck in den offenen Flaschen folgt der Kammerdruck augenblicklich. After the disturbing air has been evacuated, the desired gas or gases are admitted Usual working pressure 10 Pa. Due to the special properties of the above. Infeed with a pressure range of 100 Pa to, depending on the version, 0.01 Pa allows for the plasma, it is possible e.g. B. with the pump running, by periodic Turning the gas supply on and off varies the pressure in the chamber. The pressure in the open bottles the chamber pressure follows immediately.

Das sterilisierende Plasma "atmet" und damit wird in das Innere der Flaschen befördert. Wie gut dieses Verfahren funktionniert, haben wir bereits bei der vollständige Sterilisierung von der s. g. HELIX, einer bakteriellen Standard-Probe Probe nach DIN, bestehend aus einem bis zu 1500 mm langen und nur 1,5 mm dünn, an einem Ende geöffnet an der anderen mit einer Ampulle mit lebenden Kulturen gefüllter Schlauch bewiesen. (cf. og. OS). The sterilizing plasma "breathes" and thus gets inside the bottles promoted. We have already seen how well this process works at complete sterilization from the s. G. HELIX, a standard bacterial sample Sample according to DIN, consisting of one up to 1500 mm long and only 1.5 mm thin, open at one end at the other with an ampoule of living Cultivated tube proven. (cf. og. OS).

2) Nur Innenbehandlung2) Internal treatment only Variante 2-1 (Abb. 2. Reihe)Variant 2-1 ( Fig. 2nd row)

Die Kammer ist wie in Fall 1) gebildet. Um zu verhindern dass das Plasma um die Flasche brennt, muß der Druck in der Kammer tief genug sein, d. h. außerhalb des Paschenbereiches liegen, Typischerweise < 0.1 Pa. The chamber is formed as in case 1). To prevent the plasma from moving around the If the bottle is on fire, the pressure in the chamber must be low enough. H. outside of Paschen range, typically <0.1 Pa.

Die Flaschen werden zunächst mit der Kammer evakuiert, verschlossen und dann mit dem Arbeitsgas bei einem geeignetem Druck gefüllt. Da die PET-Flaschen für die Mikrowellen transparent sind, brennt das Plasma nur im Innern der Flaschen, die somit sterilisiert werden. The bottles are first evacuated with the chamber, closed and then filled with the working gas at a suitable pressure. Because the PET bottles for the microwaves are transparent, the plasma only burns inside the bottles, which are thus sterilized.
