NIG – Nitrogen generators

Nitrogen generator – inert push gas for beer almost free

Nitrogen generators for breweriesThe need for independence from suppliers of industrial gases leads to a search for other than traditional solutions. Small breweries must buy push gas carbon dioxide from vendors, which increases the cost of making beer. Large breweries collect the carbon dioxide produced during primary fermentation as a waste product of beer in a cylindrical-conical tanks.

For small breweries the technology to capture CO2  would be too expensive. But not on the production of nitrogen. Everyone can make their own push gas nitrogen in the microbrewery with minimal cost, using the nitrogen generator.

Nitrogen generator - schemeNitrogen generators operate on the principle of separation of nitrogen molecules from the compressed air using special membranes made of nanotechnology.

The use of nitrogen in breweries

Nitrogen is used in breweries for pushing beer, either pure (when extrude suddenly the entire contents of the container), or as a mixture with CO2 under the name BIOGON (when extrude beer from the vessel gradually over a longer period – beer stored in bright beer tanks).

Prolonged contact of beer with the nitrogen causes a decrease of CO2 content in beer – beer becomes unsaturated. In contrast, longer exposure of CO2 saturates beer.
