Abstract
Apparatus for treating plastic preforms, having a heating device for heating the plastic preforms, having forming devices for forming the plastic preforms into plastic containers, and having a sterilization device for sterilizing the plastic preforms, wherein the sterilization device has at least one first sterilization unit which has a rotatable transport carrier and a plurality of holding devices arranged on this transport carrier for holding the plastic preforms, as well as a plurality of first application devices for acting upon the plastic preforms, and the sterilization device has a second sterilization unit.
Claims20
An apparatus for treating plastic preforms with a heating device for heating the plastic preforms, wherein the heating device has a transport device for transporting the plastic preforms and at least one heating device for heating the plastic preforms, having a forming device, arranged downstream of the heating device in a transport direction of the plastic preforms, for forming the plastic preforms into plastic containers, and having a sterilization device for sterilizing the plastic preforms,
- wherein
- the sterilization device has at least one first sterilization unit which has a rotatable transport carrier and a plurality of holding devices arranged on the transport carrier and configured for holding the plastic preforms, and a plurality of first application devices configured for acting upon the plastic preforms with a flowable medium, and the sterilization device has a second sterilization unit which follows the first sterilization device in the transport direction of the plastic preforms and which has a rotatable transport carrier and a plurality of second holding devices arranged on this transport carrier configured for holding the plastic preforms, and a plurality of second application devices configured for acting upon the plastic preforms with a flowable medium, wherein the plastic preforms are transferred directly from the first sterilization unit to the second sterilization unit.
A sterilization device for sterilizing plastic containers and in particular plastic preforms, wherein the sterilization device has at least one first sterilization unit which has a rotatable transport carrier and a plurality of first holding devices, arranged on the transport carrier and configured for holding the plastic preforms, and a plurality of first application devices configured for acting upon the plastic preforms with a flowable sterilization medium, and the sterilization device has a second sterilization unit which follows the first sterilization unit in the transport direction of the plastic preforms and which has a rotatable transport carrier and a plurality of second holding devices, arranged on this transport carrier and configured for holding the plastic preforms, and a plurality of second application devices configured for acting upon the plastic preforms with a flowable sterilization medium,
- wherein
- the plastic preforms can be transferred directly from the first sterilization unit to the second sterilization unit.
A method for sterilizing plastic containers and in particular plastic preforms, wherein the plastic containers are sterilized by a first sterilization device which comprises at least a first sterilization unit which has a rotatable transport carrier and a plurality of first holding devices arranged on said transport carrier which hold the plastic preforms, and a plurality of first application devices which act upon the plastic preforms with a flowable medium, and the sterilization device has a second sterilization unit which sterilizes the plastic preforms after they have been sterilized by the first sterilization unit and which has a rotatable transport carrier and a plurality of second holding devices which are arranged on this transport carrier and hold the plastic preforms, and a plurality of second application devices which act upon the plastic preforms with a flowable medium,
- wherein
- the plastic preforms are transferred directly from the first sterilization unit to the second sterilization unit.
