US Patent 7703301 Rapid fluid cooling system and refrigeration device having same

A system for rapidly cooling a liquid in a container within a refrigerator-freezer or freezer is provided. The housing has a space for receiving a container, and a rotator rotates the container about an axis. While the container is rotating, a sprayer sprays chilled cooling medium on the container in the housing. A reservoir stores the cooling medium when the system is not being used and maintains the cooling medium at a given temperature. At least one chilling surface is preferably provided over which the cooling medium flows and where ice may be stored. A recirculator such as a pump recirculates the cooling medium throughout the system.
