  • Patent number: 7272939
    Abstract: There is a cooling system and method for its use that cools carcasses prior to their being placed into cold storage units, such as refrigeration units or freezers. The cooling system includes cooling units having a wall therein, to redirect airflow in a circular pathway from a first side of the wall to a second side of the wall. The cooling unit includes at least one cooling apparatus positioned proximate the first side of wall, for directing airflow of cooled air produced in the cooling apparatus, vertically downward in a direction toward the floor, and over the animal carcass. The wall is above the floor, such that this cooled air moves from the first side of the wall to the second side of the wall, and completes the circular pathway by returning to the area proximate to the cooling apparatus. An apparatus for creating condensation can be placed on the second side of the wall, such that condensation falls to the floor, and not into contact with the animal carcasses.

  • Patent number: 6266973
    Abstract: The present invention relates to a method and device for use in a refrigeration unit, whereby the invention causes air to flow in a circular motion whereby the air flows in an initial downward arc before flowing upward. Importantly, the present invention relates to the implementation of a wall in a refrigeration unit to cause the air to circulate in the desired motion, with such flow reducing condensation on the ceiling of the refrigeration unit and cooling animal carcasses in the refrigeration unit at a faster rate.
