A beverage cooling device which mounts on top of a cabinet so that a warm beverage, such as beer carried in a keg is cooled prior to flowing out of a faucet. The apparatus includes a cylindrical container having an evaporator coil positioned closely adjacent an inner wall and a beverage dispensing coil centrally positioned within the container. A space is provided between the inner wall of the container and the beverage dispensing coil so as to permit ice to build up on the wall of the container. A power-operated propellor is centrally located within the container for circulating water over the layer of ice and around the beverage dispensing coil to enhance the cooling of the beer flowing through the coil. A temperature sensor is carried in the water between the ice layer and the beverage cooling coil for controlling the operation of a compressor for maintaining the proper temperature of water in the container.

A refrigeration system for cooling a beverage as said beverage is drawn from a keg comprising: a container having a vertically extending wall and a top and bottom; an evaporator coil carried adjacent the wall of said container extending vertically from adjacent the bottom of said container to adjacent the top of said container; refrigeration condensing means circulating a refrigerant through said evaporator coil cooling said container; a beverage dispensing coil centrally carried within said container extending vertically from adjacent the bottom of said container to adjacent the top of said container; water carried within said container; a temperature sensor immersed in said water and being operably connected to said refrigeration condensing means for maintaining said water at a predetermined temperature; said beverage dispensing coil having a predetermined outside diameter so as to provide a space between said inside wall of said container and said beverage dispensing coil for allowing a bank of ice to build up on said inside wall; said elongated temperature sensor extending vertically downwardly in a space between said ice bank and said beverage dispensing coil from adjacent the top of said container to adjacent the bottom thereof for activating said refrigeration condensing means responsive to predetermined changes in the temperature of said water; said elongated vertically extending temperature sensor permitting the thickness of said ice bank to build up substantially for handling peak load use of said system while ensuring that said ice bank does not touch said beverage dispensing coil; a manually operated tap carried adjacent the top of said container connected to one end of said beverage dispensing coil; tubular means connecting said keg to said other end of said beverage dispensing coil so that upon opening said tap, beverage from said keg flows through said dispensing coil for being cooled prior to flowing out said top, and a power driven propeller means carried within said beverage dispensing coil for moving said water carried in said container in a circular motion for wiping said ice bank for melting said ice bank for cooling said water and said beverage dispensing coil, said flow path being substantially unimpeded between the output of said propellor and said ice bank.
