Abstract

A post mix dispensing system for mixing together and dispensing carbonated water and a flavored soft drink syrup, while generating substantially reduced amounts of foam. Carbonated water is injected into a special staging chamber, where it circulates turbulently at about atmospheric pressure. The water is ported from the chamber through a plurality of elongated ports, substantially under gravitational forces alone, and the ports are configured to straighten the flow of water and remove most of its kinetic energy. A nozzle deflects the water to converge upon a stream of syrup and to mix with the syrup in an unconfined region, after a substantial proportion of the gases released from the water has escaped, thereby substantially reducing the generation of foam.
