ABSTRACT:
An improved water carbonator system is provided for thoroughly mixing a carbonating gas with a water supply flowing through a refrigerated reservoir of the type used in soft drink dispenser stations and the like. The carbonator system includes water and gas injector nozzles disposed generally at an upper end of the reservoir, together with a dispense valve for drawing carbonated chilled water from a lower end of the reservoir. A vertically elongated and rotatably driven impeller shaft carries a spaced plurality of vaneless impeller disks for causing the water flowing downwardly through the reservoir to undergo a plurality of directional changes in a radially outward direction. Such directional changes in flow result in improved intermixing with the carbonating gas and improved chilling of the water prior to dispensing. In one form, the impeller shaft is rotatably driven by a motor mounted outside the reservoir. In another preferred form, one of the impeller disks is vaned and is positioned to be rotatably driven on an intermittent basis by a water stream discharged into the reservoir through the water injection nozzle.
