The risk of contamination is also present during the filling process. In order to avoid this, inert gases are used for conveying.
Particularly when filling carbonated beverages, the correct choice of conveying gas has to be considered. The use of pure CO2 can cause over-carbonation, whereas the use of pure nitrogen can lead to de-carbonation. Depending on the degree of carbonation in the beverage a suitable gas mixture has to be selected.
- Protection from oxidation
- By selecting a suitable gas mixture, no risk of over or de-carbonation
The supply of nitrogen gas is particularly economical and environmentally friendly thanks to Messer's Ecovap process.
