Abstract
A fruit chiller includes a bowl-like fruit container and a removable cover, each of which has a two layer wall defining therebetween annular cooling air flow passages. Cool air is delivered from a lower base and, when the cover is on the container, cool air flows upwardly through the interconnected annular passages and into the container at the top of the cover. The air flows downwardly and exits the container at the bottom, thereby maximizing the distance between the cool air inlet and outlet to maximize the time the cool air remains within the container.
