  • Patent number: 4856678
    Abstract: A beverage dispenser is disclosed which utilizes an ice water precooler. The beverage dispenser utilizes a rectangular ice bin having an aluminum cold plate in the bottom. The cold plate includes at least one vertical aperture to permit waste liquid from melting ice to run into a waste liquid tank below the ice bin. A helical concentric tube having an inner conduit substantially concentric with an outer conduit is placed in the waste liquid tank and preferably submerged in ice water. A source of beverage is coupled to the inner most conduit of the concentric tube and thereafter to a serpentine passage through the cold plate. A pump is utilized to force ice water from the waste liquid tank through a second serpentine passage in the cold plate, through the outer conduit of the concentric tube and back to the waste liquid tank. An overflow drain is utilized to limit the level of fluid within the waste liquid tank.
