Definitions

  • the invention relates to a method for sterilizing a web of packaging material, as has become known for example from DE 42 09 838 AI.
  • a packaging material web is first exposed to a water jet which is re-applied at high pressure to the packaging material web, and then exposed to UV light.
  • dust particles or accumulations of adhering to the packaging material web can be used.
  • Microorganisms are removed or killed to a high degree.
  • germs of the Aspergillus niger type are resistant to the known sterilization process.
  • the essentially mechanically acting water jet does not capture and detach all the germs of the above-mentioned, particularly UV light-resistant type on the packaging material web, in particular if it is deposited in several layers next to or on top of one another.
  • Chemical media such as hydrogen peroxide (H2O2) known that remove germs of the Aspergillus niger type from packaging material webs, but because of their chemical composition they can only be handled with great effort.
  • the method according to the invention for sterilizing a packaging material web with the characterizing features of claim 1 has the advantage that, surprisingly, not only dust particles and accumulations of microorganisms adhering to the packaging material web, but in particular also germs of the Aspergillus niger type are removed or killed without the use of chemical sterilizing agents can.
  • a device operating according to the method according to the invention has the advantage that the use of saturated steam, which is only under a relatively low pressure, means that no expensive pressure vessel is required for the sterilizing agent. As a result, the device according to the invention is particularly simple to build.
  • Packaging material web at the same time a removal of the washed away germs is achieved. Furthermore, sterile air is not required to operate suction doctor blades. However, it is also conceivable to use a combination of suction and compressed air doctor blades. By using and arranging a pair of sterile air nozzles connected downstream of the UV radiation device, the temperature of the packaging material web can be lowered in such a way that even UV radiation devices with a relatively high output and thus high heat radiation can be used without the risk of damage to the packaging material web.
  • a pair of compressed air or suction doctor blades 22, 23 follows on the further conveying path of the packaging material web 12 for its top side 1 and bottom side 2.
  • a deflection roller 24 for deflecting the packaging material web 12 from its vertical conveying direction into a horizontal conveying direction in the sterile room 10.
  • the deflection roller 24 is followed by a UV irradiation device 25, which consists of an upper part 26 and a lower part 27.
  • the blowing direction of the compressed air nozzle pair 28, 29 into the respective gaps 31, 32 between the upper side 1 of the packaging material web 12 and the upper part 26, or the lower side 2 of the packaging material web 12 and the lower part 27.
  • saturated steam with a pressure of approximately 2 to 5 bar (corresponds to a temperature of approximately 120 to 160 degrees Celsius) was used.
  • the UV irradiation device 25 had an output of approximately 500 milliwatt seconds / c, and the irradiation time for the packaging material web 12 was in the range from 1 to 10 seconds.
  • kill rates greater than 6 orders of magnitude could be achieved.
  • the device 11 described above can be modified in an advantageous manner in that the area of the steam cleaning, that is to say in particular the area of the doctor blade pairs 17, 18 and 19, 20, is designed to be largely closed, so that no steam vapor reaches the area of the UV radiation device 25 .
  • Sterility rate of the packaging material web 12 is also conceivable to provide only a single or a repeated saturated steam treatment instead of a double saturated steam treatment of the packaging material web 12.

Abstract

Le dispositif décrit (11), qui sert à stériliser une bande (12) de matériau d'emballage, présente deux paires de racles (17 à 20) pour vapeur saturée et un dispositif d'irradiation aux U.V. (25) en aval de celles-ci. L'utilisation de vapeur saturée à une température comprise entre 120 et 180 degrés Celsius, associée au dispositif d'irradiation aux U.V. (25), permet d'éliminer ou tuer de manière appropriée les germes présents sur la bande (12) de matériau d'emballage sans utiliser des substances stérilisantes chimiques.
