ABSTRACT:
A cooling system for a food storage and merchandising machine having a rotatable drum mounted inside a cabinet, the drum having a plurality of axially spaced shelves divided by partitions into a plurality of food storage compartments, comprising a hollow center column extending axially through the drum and through the centers of the shelves, the column having a sidewall defining an air passageway, the sidewall having a plurality of vents therein communicating with each of the food storage compartments. The system further comprises a refrigeration system for cooling air, and a blower for introducing cooled air into one end of the air passageway. The other end of the air passageway is closed so that substantially all of the air provided to the passageway passes through the vents. An air return duct, formed by at least one inner wall disposed remote from the drum, adjacent the walls of the cabinet, receives air which has passed from the air passageway through the compartments, and returns the air to the refrigeration system.
