  • 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 in the bottling plants are industrially and automated, 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.
  • treatment systems for filling and/or cleaning KEGs with integrated cleaning are provided in the prior art, so that the KEGs can be used several times as reusable containers.
  • the impurities are product-dependent. For example, unfiltered beers, keg-fermented beers and quas lead to 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 systems can be influenced in particular by the factors of time, temperature, cleaning media used (chemistry) and mechanical action of the cleaning medium on the residues. It is known here that the cleaning effect can be improved by optimally setting the temperature of the treatment media.
  • the temperature of the cleaning media is often in a high temperature range, for example approx. 85°C in the case of hot water or from 105°C to approx. 125°C in the case of steam at overpressure.
