A METHOD AND A SYSTEM FOR PRESSURISING AND DISPENSING CARBONATED BEVERAGES

摘要

A self regulating and constant pressure maintaining beverage dispenser assembly comprises a dispensing device and a beverage container defining an inner space constituting a beverage space filled with carbonated beverage and communicating with the dispensing device for allowing dispensation of the carbonated beverage, and a head space communicating with the beverage space and filled with CO2 having an initial pressure of 0.1-3 bar above the atmospheric pressure when subjected to a specific temperature of 2°C-50°C preferably 3°C-25°C and more preferably 5°C-15°C. The beverage dispenser assembly further comprises at least one carbonisation canister communicating with the head space via a hydrophobic labyrinth and comprising a particular amount of adsorption material having adsorbed a specific amount of CO2. The particular amount of adsorption material is inherently capable of regulating the pressure in the head space and of preserving the carbonisation of the carbonated beverage in the beverage space by releasing CO2 into the head space.
