Carbonation system for soft drink dispenser

摘要

A carbonation system for a soft drink dispenser in which water is precooled and then introduced into an insulated tank where it is subjected to pressurized carbon dioxide. A pressure transducer monitors the pressure within the tank, with the dispensing of soda from the tank being regulated on a timed basis as a function of such pressure. The tank is periodically emptied and refilled to assure that the soda generated therein is fresh.
