Abstract

An apparatus for stabilizing food products prior to freezing thereof comprises a frame defining a vertical channel. A plurality of rollers are rotatably mounted in the frame and form a substantially horizontal conveyor across the channel. The rollers are rotated in a direction providing conveyance of food products thereon. Cold gas is blown up through the channel and between the rollers, such that a thin bottom layer of each one of the food products is frozen during conveyance thereof on the rollers across the channel.
