Abstract
An enclosure is divided by partitions to define a narrow sinuous passageway for the passage of carcasses from an inlet to an outlet. The sinuous passageway defines adjacent aisle portions and a blower directs refrigerated air downwardly over the carcasses in one of the aisle portions. The air passes under the dividing partition into the adjacent aisle portion and the blower draws it upwardly over the carcasses in that adjacent aisle portion to rapidly freeze a crust on the carcasses during their passage from the inlet to the outlet. The method of the invention is the blowing of cold air over a carcass in one vertical direction then over the same carcass in the opposite vertical direction.
