Method and apparatus for dispensing a beverage from a liquid concentrate

摘要

A nozzle system for use with a multi-flavor beverage dispenser includes a mixing chamber having a fluid outlet therefrom; a diluent injector configured to deliver a mixing fluid from without to within the mixing chamber; and a number of concentrate injectors configured to independently deliver a fluid concentrate from without to within the mixing chamber. The concentrate injector each have associated therewith a self-sealing dispensing valve configured to substantially limit fluid flow through its respective concentrate injector to from without the mixing chamber to within the mixing chamber.

1. A nozzle system for use with a multi-flavor beverage dispenser, said nozzle system comprising:
a nozzle body defining an injector housing, a mixing chamber, and an outlet from said mixing chamber; an injector body disposed within said injector housing, said injector body defining:
a diluent manifold formed circumferentially about an outer and a lower portion of said injector body, said diluent manifold communicating with said mixing chamber,a first concentrate injector port formed through said injector body interior of said diluent manifold such that said first concentrate injector port communicates with said mixing chamber without intersecting said diluent manifold,a second concentrate injector port formed through said injector body interior of said diluent manifold such that said second concentrate injector port communicates with said mixing chamber without intersecting said diluent manifold, anda diluent injector port formed in an outer portion of said injector body exterior of said first and second concentrate injector ports such that said diluent injector port resides over and communicates directly into said diluent manifold; a first concentrate injector disposed within said first concentrate injector port, said first concentrate injector coupled with a first concentrate source for delivering concentrate to said mixing chamber; a second concentrate injector disposed within said second concentrate injector port, said second concentrate injector coupled with a second concentrate source for delivering concentrate to said mixing chamber; and a diluent injector disposed within said diluent injector port, said diluent injector coupled with a diluent source for delivering diluent to said diluent manifold, wherein said diluent manifold delivers said diluent circumferentially into said mixing chamber.
