Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • microbiologically sensitive products are characterized as follows:
  • Alcohol content between 0 and 0.5 volume%
  • peracetic acid attacks the stainless steel of the system components and leads to corrosion there;
  • Chlorine dioxide concentration of more than 1, 5 ppm also leads to corrosion of stainless steel plant components
  • Chlorine dioxide concentration of 1, 5 ppm and higher leads to a high odor nuisance.
  • the object of the invention is to provide a method which avoids the aforementioned disadvantages and with which in particular a shortening of the treatment time or duration is achieved.
  • a method according to claim 1 is formed. It has surprisingly been found that with a chlorine dioxide concentration below 0.8 ppm in the aqueous solution of chlorine dioxide used as a treatment medium
  • the object of the invention is to provide a method which avoids the aforementioned disadvantages and with which in particular a shortening of the treatment time or duration is achieved. To solve this problem, a method according to claim 1 is formed.
  • the invention is further based on the finding that the exposure time of the treatment medium formed by the aqueous solution of chlorine dioxide, ie the duration of treatment in the respective treatment steps can be significantly reduced, without the desired effect being impaired or get lost.
  • a contact time or treatment time of 1 to 2 seconds in the treatment of the packaging and a contact time or treatment time of 5 to 10 minutes in the treatment of critical areas of the system components is quite sufficient.
  • critical areas of the plant components are, in particular, those areas and / or areas of the machines or components of a plant which come into contact with the respective product during product filling and / or with a treatment medium for pretreating the packaging prior to their filling ,
  • packaging means are packagings or containers which are customarily used in the foodstuffs sector and especially also in the beverage sector, in particular containers, such as bottles, cans or soft packagings, for example those made from cardboard and / or or plastic film and / or metal foil, etc.

  • FIG. 1 shows essential treatment steps of a process for internal cleaning and / or disinfection and / or sterilization of containers 2, which are subsequently filled with a product, in particular with a product which has a high sensitivity to microbiological and product-damaging contamination or contamination Contaminated.
  • the cleaning and / or disinfection and / or sterilization of the containers 1 take place in such a way that in a first treatment step BS1 an internal spraying of each container 1 with chlorine dioxide (CIO 2) dissolved in water, ie. with an aqueous solution of chlorine dioxide, namely at a chlorine dioxide concentration in this first treatment medium between 0.4 ppm and 0.8 ppm.
  • the treatment time is preferably only 1 to 2 seconds in the treatment step BS1.
  • the containers 1 are then sprayed again with the aqueous solution of chlorine dioxide, specifically with a chlorine dioxide concentration in the range between 0.2 and 0.4 ppm.
  • the treatment time is again, for example, 1 to 2 seconds, but preferably only 0.5 second.
  • the containers 1 are already available in the clean or cleaned state at the beginning of the process, for example immediately before cleaning and / or disinfecting and / or sterilizing e.g. as a plastic container, e.g. PET containers or PET bottles were made by blow molding.
  • the containers are reusable containers, then prior to the process described above, i. Before the treatment step BS 1, the cleaning of the container with the usual cleaning method or in a conventional container cleaning machine.
  • an external cleaning and / or disinfection and / or sterilization is carried out, for example the container 1, at least at such areas of the container outer surface, the risk of bacterial contamination of the product when filling the container 1 and when closing the respective filled container 1.
  • FIG. 2 shows in a flow chart the treatment steps of a method according to the invention for internal cleaning and / or disinfection and / or sterilization of containers 2 in the form of KEGs which are essentially made of a large-volume, eg made of metal or plastic (PET) Container body 3 with a valve having a KEG fitting 4 on the KEG top, as well as for the cleaning and / or disinfection and / or sterilization of the respective KEG fitting 4 and its components.

  • the KEG fitting 4 is opened and the container 2 is emptied of product residues.
  • a rinsing of the container interior with a rinsing or cleaning liquid, for example with alkali and / or acid takes place via the treatment head 5 and the opened KEG fitting 4.
  • a flushing of the container interior with water takes place via the treatment head 5 and the opened KEG fitting 4.
  • temporally following treatment steps BS4a and BS5a then the actual treatment of the container interior and also all, coming into contact with the product surfaces or areas of the KEG fitting 4, in particular all surfaces and areas of the local valve with the cleaning and / or disinfecting medium of water and chlorine dioxide, specifically in the treatment step BS4a with the aqueous solution of chlorine dioxide and having a chlorine dioxide concentration in the range between 0.4 ppm and 0.8 ppm, the treatment time being for example 1 to 2 seconds.
  • the treatment is carried out with the aqueous solution of chlorine dioxide and with a chlorine dioxide concentration in the range between 0.2 and 0.4 ppm, wherein the treatment time is about 1 - 2 seconds, preferably only 0.5 seconds.
  • a complete emptying of the container interior from the treatment medium then takes place when the container 2 is arranged at the treatment head and the KEG fitting is open.
  • an action on the KEG fitting 4 takes place above the treatment head 5 such that a Sealing ring, which is usually arranged between the KEG fitting 4 and the inner surface of the container body 3 and the local junction between KEG fitting 4 and container body 3 seals, is lifted from the inner surface.

  • the respective treatment medium is slid in a closed flow path through the system components 6 to be rinsed and / or cleaned and / or disinfected and / or sterilized (CIP cleaning and / or sterilization).
  • the method of Figure 3 offers significant advantages in terms of energy and cost savings, since the previously usual, 20 to 30 minutes lasting treatment of the system components with hot water and / or steam can be dispensed as a disinfectant.
  • a particular advantage of the method according to the invention is also that the temperature of the treatment medium has no significant effect on the quality of the cleaning and in particular the sterilization, ie a tempering or heating of the treatment medium can be dispensed with, in spite of the low chlorine dioxide Concentration in the treatment medium.
  • Another advantage is that basically no sterile water, ie a water sterilized in a complicated manner, is required for the treatment medium. This results in significant savings in terms of energy consumption and costs.
