A BEVERAGE DISPENSING SYSTEM

摘要

A beverage dispensing system and distributing process with such a system has a flexible bag 1 containing the beverage which may have carbon dioxide dissolved therein. The beverage is drawn off through a pipe 3 (assisted by a pump 8) for dispensing through nozzle 5 having a tap 6. Carbon dioxide, nitrogen (or other inert gas) and/or air gases are introduced into the beverage through a passage 11 by way of a fixed orifice restrictor 12 and a non-return valve 13. The pressure of the gas which is introduced is adjustable at 14 and baffles 15 can provide turbulence in the beverage during dispensing to promote the dissolution of the introduced gas therein. The facility to introduce the gas or gases permits the beverage in the bag 1 to have a low content of carbon dioxide so that the bag collapses under atmospheric pressure while the beverage as dispensed is additionally gasified for the formation of a froth or head.
