Abstract: A beverage dispensing valve may include an inlet to receive carbonated water, a nozzle shell, and an outlet downstream of the nozzle shell configured to dispense a finished beverage. The nozzle shell may include an aperture open to ambient pressure environment. A method for dispensing a beverage may include flowing carbonated water through an inlet of a beverage dispensing valve, lowering the pressure of the carbonated water sufficient to promote carbon dioxide nucleation, flowing the carbonated water through a chamber vented to environment such that a portion of carbon dioxide nucleated is off-gassed, and introducing a beverage ingredient when the carbonated water reaches a sufficiently low carbonation level. A beverage dispensing nozzle may include an inlet configured to receive carbonated water from a beverage dispensing valve, a nozzle shell including an aperture open to ambient pressure environment, and an outlet downstream of the nozzle shell configured to dispense a finished beverage.

Abstract: Embodiments described herein relate to systems and methods for carbonating a liquid at ambient temperature. The system may include a liquid source; a carbon dioxide source; and a contactor for carbonating the liquid. The contactor may include channels and a sparge for carbonating liquid flowing through the channels. The system may produce a liquid having high levels of carbonation at ambient temperature. The sparge may generate microbubbles or nanobubbles to allow for cost-effective carbonation at ambient temperatures. The bubbles may have an average diameter of 100 μm or less. The system may carbonate liquid at a rate of 1 gram to 10 grams carbon dioxide per liter.
