The present invention relates to equipment for ultra-rapid freezing of foods contained in packaging having multiple cavities for sale to the public and through application of a stream of liquid nitrogen in an amount sufficient to cause ultra-rapid freezing of the food. Liquid nitrogen is dispensed gravitationally from a vacuum-insulated container at atmospheric pressure by a plurality of nozzles at the center of the upper surface of each cavity and there by leading to brief immersion in the individual cavity the gaseous nitrogen generated is used to create a substantially oxygen-free atmosphere COLD enough to sustain th freezing process following such dispensing. The process decreases the amount of liquid nitrogen required compared with other freezing processes, as well as the personnel, equipment and physical space necessary for installation and operation thereof and thereby reducing the associated costs.
