A B S T R A C T Improved chilling apparatus for aircraft meal tray storage and/or serving carts utilizes a slidable tray type of bunker member for receiving dry ice or other cooling material. The bunker member is preferably of thermoformed plastic, is insulated on its bottom and sides, and has a channeled bottom which supports pieces of dry ice while permitting air to be circulated by a blower under the dry ice pieces as well as around and over them. At its downstream end, the bunker has an air flow turning surface and an air discharge opening through its bottom. At its upstream end, an opening directs return air which has passed over the meal trays to an angularly posi- tioned blower located in the cart housing above the inlet end of the bunker.
