A product such as ground meat is efficiently chilled in a blender device having an open top. Liquid carbon dioxide is introduced into the blender at a location below the surface of the product to thereby form solid and gaseous CO2. Mixing elements such as a ribbon screw or the like are operated to pass the product in a countercurrent relation to the carbon dioxide introduced into the blender thereby chilling the product and causing the resulting CO2 gas to rise along one wall of the blender. Deflector means are provided along such wall to direct the rising vapor toward an exhaust plenum located above the open top of the blender.

The method of chilling a product in a blender device comprising the steps of introducing said product into a trough of the blender; introducing liquid CO2 into the product at a location below the surface of the product to form solid and gaseous CO2 in the trough; mixing said product with said CO2 by passing said product countercurrent to the direction in which said CO2 is injected into said trough to chill said product with a major portion of said gaseous CO2 rising substantially along one wall of said trough; and deflecting said major portion of gaseous CO2 as the same rises above the trough toward an exhaust device located above the open top of said trough.
