Today in 2003, US 6622510 B2 was issued, an invention of Mark S. Giroux, Joseph M. Trewhella, and Darryl Alan Goodson, assigned to Grindmaster Crathco Systems, Inc., for their “Frozen Beer Product, Method and Apparatus.” Here’s the Abstract:

A method of freezing and dispensing a beer product comprises providing beer in a sealed, refrigerated storage container under pressure; feeding beer from the storage container to a sealed freezing chamber through a sealed delivery system; freezing the beer in the chamber; and dispensing frozen beer from the chamber.

The frozen beer product preferably has a slush consistency and a density of about 50% to about 90% of the density of unfrozen beer, a temperature of between about 23° and 27° F. and a volume reduction in a filled 14 fluid ounce plastic cup sitting in 70° F. room for 30 minutes or less than 10%.

A refrigerated cabinet for supplying beer comprises an insulated beer storage compartment; a refrigeration system comprising a compressor, a condenser, a thermal expansion device and an evaporator; a pressurized carbon dioxide tank in a separate, non-refrigerated compartment; and a fan for circulating air within the insulated beer storage compartment.

A beer freezing and dispensing apparatus comprises a freezing chamber; a refrigeration system for cooling the beer in the freezing chamber to a frozen state; a dispensing system for dispensing frozen beer from the freezing chamber when it reaches a slush consistency, and a beer delivery system for delivering beer to the freezing chamber, the beer delivery system comprising; a valve for controlling the introduction of beer into the delivery system; a check valve to prevent beer from flowing backwards out of the delivery system; an accumulator for holding beer that expands when beer freezes in the chamber; and a pressure sensor for sensing the pressure of the beer between the accumulator and the freezing chamber.

The method and apparatus may also be used to freeze and dispense other single-strength beverages.

    OMG – Beer “Slurpees” (or ICEE’s). Add tequila & lime for a “beergarita” (but the beer would have to be something like EKU 28 to substitute for tripel sec) 🙂
