ABSTRACT:
Chilling apparatus especially adapted for airline food tray serving carts has a small blower at one upper end of the inside of the cart which exhausts air across a pan of dry ice or other cooling material removably positioned on an upper shelf of the cart. Spacer means in the cart enclosure prevent the trays stacked therein from blocking a vertical air flow passage at each end of the cart. Thus, the chilled air is directed downwardly from the pan over the inside wall of a door on the cart. The chilled air then passes horizontally over at least a portion of the trays containing items to be chilled and is sucked upwardly along the other inside end wall of the cart to the blower inlet duct. The apparatus is very light in weight and can provide sufficiently uniform cooling to the items on each tray which must be chilled when a container on each tray is being simultaneously heated.
