Patent attributes
A system and method for the automated dispensing of bulk keg wine is provide having, in combination: integrated temperature control; pressure monitoring; automated purging; and integrated point of sale data acquisition for determining inventory usage statistics for each keg of wine dispensed. The system provides for precise measurement of each portion. Control algorithms for adapting system operation provide anticipated travel time and distances, and anticipated dispensed volumes and volumetric flow rates to allow for precise control of selected pour volumes. A relationship is calibrated among applied pressure, piston delay time, and dispensed per push volume to achieve higher control accuracy between a maximum and minimum system pressure ranges.
