Frozen beer product, method and apparatus

摘要

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.
