Abstract
A device for sterilizing containers includes a first treatment space, which is filled with a sterilizing gaseous medium under predetermined thermodynamic conditions, a tank, which is filled with a liquid medium and extends along a closed path, and a multiplicity of holding devices for holding the containers. The holding devices are arranged rotatably with respect to the treatment space, and a dividing wall, which protrudes into the liquid medium located in the tank is arranged rotatably with respect to the tank. A discharge opening, via which the gaseous medium can be discharged, is provided between the treatment space and the tank.
Claims19
A device for sterilizing containers, comprising a treatment chamber which is filled with a sterilizing gaseous medium under predefined thermodynamic conditions, a tank which is filled with a liquid medium and which extends along a closed path, a plurality of holding devices for holding the containers, wherein the holding devices are rotatable relative to at least one of the walls forming the treatment chamber, and a separating wall which protrudes into the liquid medium located in the tank and rotatable relative to the tank, wherein a discharge opening located below a fill level of the liquid medium, via which the gaseous via which the gaseous medium can be discharged, is provided between the treatment chamber and the liquid medium located in the tank, and wherein a buffer chamber for the gaseous medium is provided between the treatment chamber and the liquid medium located in the tank, wherein the medium in the buffer chamber is maintained at a lower pressure than in the treatment chamber such that the gaseous medium passes from the treatment chamber into the buffer chamber.
A device for sterilizing containers, comprising a treatment chamber for holding a sterilizing gaseous medium under predefined thermodynamic conditions, a tank for holding a level of liquid medium, a plurality of holding devices for holding the containers, wherein the holding devices are rotatable relative to at least one of the walls forming the treatment chamber, and a separating wall which protrudes into the tank below the level of liquid medium and rotatable relative to the tank, wherein a discharge opening, via which the gaseous medium can be discharged, is provided between the treatment chamber and the tank, and wherein a buffer chamber for the gaseous medium is provided between the treatment chamber and the tank, adapted to maintain the gaseous medium in the buffer chamber at a lower pressure than in the treatment chamber such that the gaseous medium may pass from the treatment chamber into the buffer chamber, wherein said discharge opening is adjoined by a discharge pipe for the gaseous medium, which extends partially through the tank.
