Problems solved by technology

However, since the containers are conveyed by the conveying device, there must be container surfaces which are excluded from the plasma disinfection effect.
In addition, the plasma discharge pressure is at a level requiring high technical costs and thus detrimental to work efficiency

Embodiment Construction

[0015] According to this figure, a plurality of sterilization chambers 1 can be arranged on the periphery of a revolving gantry 2 whose conveying movement direction is indicated by A. In FIG. For example, there may be 100 such sterilization chambers 1 . Each sterilization chamber 1 accommodates a container 3 to be sterilized. The containers 3 are supplied to the revolving crane 2 in the conveying direction B, for example by means of a conveying device 4 which is only schematically indicated. Via a star feed 5 that rotates in the direction of the arrow, the containers 3 continuously reach the area below the sterilization chamber 1 and enter the sterilization chamber. Accordingly, there is a star-shaped delivery mechanism 6 rotating in the direction of the arrow, by means of which the sterilized and possibly filled closed containers 7 are sent out again in the delivery direction C by a delivery device 8 .

[0016] If, for example, the revolving gantry 2 is equipped with fifty ...

Abstract

A device for sterilizing containers (3) which are to be filled comprising a plurality of sterilization chambers (1) which respectively accommodate one container (3) and which are driven, for example, by a rotary device (2) in a continuous or clocked movement of conveyance. The sterilization chambers (1) pass through at least two fixed sectors (b, e) at specific intervals, a low-pressure chamber (10,11) having a different pressure level being respectively associated therewith and said sterilization chambers (1) being able to be connected thereto. The first low-pressure chamber (10) associated with the first sector (b) has a pressure level which enables a vaporous mixture comprising water vapor and hydrogen peroxide vapor to flow into the sterilization chambers (1) and become condensed on the surfaces of the container to be sterilized (3). The low-pressure chamber (11) associated with the second sector (e) has a pressure level at which both components of the condensate evaporate in order to remove the thus formed condensate from the sterilization chambers.

Description

technical field [0001] The invention relates to a sterilizing device for containers to be filled, which has a plurality of sterilizing chambers which can be driven according to a continuous or clocked conveying movement and each receive a container, the sterilizing chambers passing through at least two In the fixedly arranged regions, each of the at least two regions is assigned a vacuum chamber with a different pressure level, with which the sterilization chamber can communicate. Background technique [0002] Such a device is known from the prior art DE 199 16 478 A1. In this known device, the sterilization chamber is designed in the form of a reactor in which decibels sterilize a container by means of low-pressure plasma. For this, these sterilization chambers must be evacuated from atmospheric pressure to plasma discharge pressure. The disinfection effect of plasma is not only based on the mechanical killing effect of ion bombardment on germs, but also on the chemical k...
