Definitions

  • the present invention relates to a cleaning module for the stationary exterior cleaning of KEG containers, and to a treatment system for cleaning and filling KEGs with at least one such cleaning module for the stationary exterior cleaning of KEGs. Furthermore, the present invention also relates to a method for the stationary exterior cleaning of KEGs with such a cleaning module.
  • KEGs which are also referred to as KEG barrels or KEG containers, offers numerous advantages.
  • a main advantage of using KEGs is that these barrel-like containers are hermetically sealed due to a particularly advantageous design of the connections for filling goods and compressed gas and thus the filling goods and interior of the KEG are protected from all kinds of dirt, but especially from contact with germs.
  • the specialist knows the connections of KEGs as fittings or KEG fittings.
  • the relevant specialist has therefore long been familiar with the basic structure of such KEGs with at least one KEG fitting and usually represents a two-way valve at the inlet and outlet of the KEG of the treatment station opened in the cleaning and/or filling step.
  • the KEGs are handled industrially and automatically in the bottling plants, in particular in the large plants in the beverage industry, for example cleaned and/or filled or refilled.
  • the KEGs are filled with liquid contents, particularly in fully automated individual machines with one filling station or in large machines with several filling stations.
  • the KEGs are often reusable containers, they have to be cleaned inside and out before they can be reused due to the high cleanliness requirements that are customary in the food industry.
  • separate treatment modules are provided in the prior art for filling and/or cleaning KEGs with external cleaning, so that the KEGs can be used several times as reusable containers.
  • the impurities are product-dependent. For example, when cleaning the interior of KEGs, unfiltered beers, barrel-fermented beers and Quas leave significant residues in the interior of the container, which are difficult to remove.
  • the cleaning intensity of cleaning methods known from the prior art in such treatment plants during the transport of the KEGs through a tunnel with e.g. washing shower and brushes can be influenced in particular by the factors of time, temperature, cleaning media used (chemicals) and a mechanical effect of the cleaning medium on the residues become. It is known here that the cleaning effect can be improved by increasing the temperature or by adjusting the temperature optimally as a function of the treatment media. It is also known that the cleaning effect can be improved by extending the cleaning time.

  • the washing device is designed to apply the cleaning agent and/or water jet generated by the washing device to at least sections of the outer surface of the individual KEG and/or an upper side of the KEG comprising the KEG fitting and/or an underside of the KEG. It is particularly advantageous to be able to flexibly adjust the cleaning of the KEGs, since only a single KEG is cleaned on the outer surface of the cleaning module designed as a “stand alone” module. It is therefore no longer necessary, as in the prior art, to clean all the KEGs during the transport of the KEGs within the treatment plant, rather they can now be cleaned outside in a stationary manner in the cleaning module designed according to the invention as an individual module. This cleaning can be adjusted individually and according to the needs of the individual KEG in terms of effort and length of the cleaning process.
