US Patent:

48523658, Aug 1, 1989

Filed:

Jul 19, 1988

Appl. No.:

7/224500

Inventors:

Granville P. Elrod - Murfreesboro TN
John W. Westbrooks - Christiana TN
Tracy L. McDonald - Winchester TN

Assignee:

Standex International Corporation - Salem NH

International Classification:

F25D 1500

US Classification:

62237

Abstract:

A refrigeration system comprised of a walled insulated enclosure is provided with a drive motor having a drive shaft extending therefrom. The drive shaft and drive motor are positioned along the ceiling of the walled enclosure. The drive shaft terminates at a coupling mechanism. A complimentary coupling mechanism is attached to the top of a well-known movable food rack. Thus, when the food rack is stored within the walled enclosure, the coupling mechanism on the food rack mates with and attaches to the complimentary coupling mechanism of the drive shaft. When the drive motor is actuated, the drive shaft will rotate the movable food rack. It will be appreciated that by rotating the movable food rack, the present invention will permit the food stored on the food rack to chill far more quickly than if the food rack were to remain stationary. In addition, by rotating the food rack, the present invention eliminates warm air pockets which allow bacterial growth. As a result, the present invention provides less food spoilage relative to prior art refrigeration systems and therefore is more economical to the food service industry user.
