Abstract

A rotary freezer for cooling resilient golfball centers to a uniform, substantially rigid state is provided with a dispenser to permit dispensing of rigid centers in one-at-a-time fashion from a large batch of frozen centers in the freezer at a rate indepenent of the residence time. As the freezer drum rotates, paddles on the inner circumference serve to lift randomly-selected centers from the batch to a predetermined height for gravity loading onto an inclined rack forming a part of the dispenser. Centers on the rack are arranged in a rectilinear series leading to an outlet port where a metering assembly controls dispensing of the centers from the drum in one-at-a-time fashion at a rate determined by the operator. A gravity conveyor exterior of the freezer drum transports each dispensed center from the outlet to a work station where the winding process is to be initiated before the center returns to its resilient state. In preferred forms, the freezer has a pair of dispensers, each with its own conveyor whereby two winding stations may be served. The freezer is designed to use liquid CO.sub.2 as a refrigerant for more efficient operation.
