Bottle Wash Process


The cleaning of casks, kegs, and bottles varies depending on the material, the beer type, the machine type and the cleaning philosophy in the brewery. Cleaning ranges from cold and hot water sprays with a final steam disinfection to complex cleaning sequences including cold and hot rinses, hot alkaline cleaning (75 – 85°C) and hot acid cleaning (60 – 70°C). The efficiency of the final steam disinfection can be increased by injection of suitable disinfectants. Finally cleaned containers are visually inspected for cleanliness.

A specific problem in cleaning can be residual carbon dioxide that reacts with alkaline cleaning solutions by converting sodium hydroxide of the washing solution to sodium carbonate or bicarbonate. CO2-purging systems have often been not as effective as intended. In many cases, it was possible to introduce a single stage acid cleaning to solve the CO2-problem.
