  • Patent number: 7743624
    Abstract: A beverage dispense font incorporating a portable cooling device is provided wherein the portable cooling device cools an outer housing of the dispense font in order to encourage ice formation on the dispense font. Unique visual effects can be obtained with ice formation on the outer housing of the dispense font, and the portable cooling device therefore enables independent cooling of the outer housing without redesign or modification of the existing glycol cooling system used to cool the dispensed beverage. The portable cooling device can be inherently small in size due to relatively minimal cooling capacity requirements for cooling just the outer housing of the dispense font. The dispense font and portable cooling device may be moved from location to location thereby greatly enhancing the capability to provide a frozen-appearing dispense font to many locations.

    Abstract: A cooling, carbonation and dispensing system for use with a liquid in a keg includes a cooling ring mounted on top of the keg. The cooling ring includes a toroidal-shaped shell into which dry ice is placed. The cooling ring and dry ice provide contact cooling of the keg, as well as carbon dioxide gas by sublimation of the dry ice to carbonate the liquid in the keg and pressure on the liquid so that it may be dispensed from the keg. A chilling unit having a hose bundle is mounted on top of the cooling ring. A liquid dispensing hose from the keg coupler on the keg connects to the hose bundle, so that liquid from the keg passes through the hose bundle. A lid having a tower is attached to the top of the chilling unit and latched to it to form a water-tight seal. Another hose connects to the hose bundle in the chilling unit and conducts the liquid to a dispensing hose attached to a dispenser in the tower.
