Brewery Locher AG installs ASCO CO2 Vaporizer for brewing & bottling

Beer is an oxygen-sensitive beverage that is produced and bottled without preservatives. Therefore, CO₂ is used as a protective gas in the brewing process and during bottling. The liquid CO₂ is first converted into its gaseous state by an ASCO atmospheric CO₂ vaporizer. In order to be able to supply production and filling with enough carbon dioxide at the same time, a vaporizer with a capacity of 300 kg/h was installed. Beer bottles and barrels are first filled with carbon dioxide gas, this process is called "pre-stressing". The beer is then filled into the bottles and barrels under counterpressure to prevent foaming. This low-air and thus low-oxygen filling process ensures that the bottled beer retains its flavour for a long time.
