ABSTRACT:
A new and improved device having a chamber for the receipt of food products to be instantly frozen comprising a container having side walls and a rear wall in a vertical orientation and having a top wall and a bottom wall the edges of which are coupled to the edges of the side and rear walls, and having an opening at the front thereby forming a chamber within the walls. A door is positionable over the open front with a hinge coupling the side of the door with an adjacent edge of the container. A manifold is positioned within the chamber and secured to depend from the upper wall with openings spaced along its lower extent and a central passageway extending therethrough. A tube couples the manifold with a source of freezing gas located exterior of the device. Control means are adapted to project a flow of freezing gases from the container through the tube to the manifold for being dispensed to food products located within the chamber to be frozen.
