Advantages of using chlorine dioxide in brewing industry

Abstract

In a brewery it is very important to ensure hygienic conditions. Chlorine dioxide is a multispectral disinfectant that is more powerful, easier to use, and more environmentally friendly than chlorine. Usage of chlorine dioxide in a brewery has a lot of advantages because it can be used in different places for different purposes. Chlorine dioxide is able to penetrate, disrupt and destroy the biofilm where chlorine is completely ineffective. The main applications include, cleaning in place process (CIP) and sanitizing operations. It is noticed that chlorine dioxide is very effective especially when it is used as the final sanitizing rinse agent in CIP systems. The second application most important is to control biofilms found randomly on heat exchange surfaces, in pipes, lines, orifices pumps, conveyors, chains etc. In the form of spray solution can be used as a manual sanitizing agent for different surfaces such as for example, filler head assemblies during filling process. A very important application is at water filtration and distribution system disinfection. Chlorine dioxide is very effective when it is used for water disinfection both used for drinking and housekeeping. Ambient hygiene control especially in filling line is very important. Misting of chlorine dioxide solutions into air streams prevents the spread of mould and wild yeast. Chlorine dioxide is also an excellent odor neutralizer, helping to control mould and odor control. This process controls 'off-tastes' in the final product. Chlorine dioxide solutions are also very effective for sanitizing and removing biofilms from the internal surfaces of transportation vessels. In order to have optimal results it is needed a careful study, because for each application the range of concentration and contact time is different. On the other hand it is very important to control his corrosive properties.
