Comparison of different cleaning methods for beerdispense equipment

摘要

The aim of this work is to gain cognition about the efficiency of different methods for beerrnline cleaning in order to find the most effective and most economic one. The followingrnmethods are examined: mechanical cleaning by using a sponge ball, static caustic cleaning,rncaustic circulation cleaning, combined caustic and mechanical cleaning. Furthermore, thernexperiments are carried out for beer lines of different ages, so that an possible influence ofrnaging on the cleanability can be detected.rnThe results show clear differences between the compared cleaning methods, with mechanicalrncleaning as the worst of the tested ones. Additionally, a strong influence of beer line aging isrnobvious.
