ABSTRACT:
A refrigerated appliance for use as a salad bar includes an enclosure having a refrigeration unit mounted therein and a cooled food storage compartment. An upper wall of the storage compartment is provided with openings for receiving a plurality of foodstuff containers having bottom wall surfaces which extend into the compartment. An air inlet opening from the refrigeration unit is disposed proximate to the upper wall of the compartment and cool air issuing therefrom is directed at the exposed wall surfaces of the containers. To concentrate the air flow at the containers a duct surrounds the air inlet opening and is spaced closely from the containers. A free end of the duct is open to the storage compartment for circulation of the air through the compartment. Proper sizing of the duct permits the air within the duct to be maintained at a temperature lower than the temperature of the compartment, whereupon perishable refill foodstuffs for the containers may be stored within the compartment while the containers may be chilled to much the same degree as in a conventional ice-type salad bar unit.
