Benefits of technology

[0010]Briefly described, the present invention relates to an auger chiller for reducing the temperature of previously eviscerated bird carcasses or the like, which may include carcasses of other types of animals.
[0011]An embodiment of the chiller includes an elongated tank for receiving the carcasses and chilled water is introduced into the tank for reducing the temperature of the carcasses. The tank includes a main segment with a substantially constant radius semi-cylindrical bottom wall, and an exit portion having an upwardly converging bottom wall, tapered to a breadth smaller than the constant radius of the main segment bottom wall.

Problems solved by technology

Some of the birds received in the tank typically are expected to be negatively buoyant, having a density slightly greater than the mass of water, such that the birds tend to sink in the water toward the cylindrical bottom wall of the tank.

Embodiment Construction

[0023]Referring now in more detail to the drawings, in which like numerals indicate like parts throughout the several views, FIG. 1 illustrates an auger chiller 10 with a sloped bird unloader 12, with the auger chiller including an elongated tank 14 for receiving bird carcasses, with a carcass entrance end 16, a carcass delivery end 18, and a main tank segment 20 extending between the ends.

[0024]As shown in FIG. 1, a chilled water recirculation system 22 is provided for reducing the temperature of the water being recirculated from the carcass entrance end 16 to the carcass delivery end 18, thereby forming a counterflow relationship between the chilled water and the oncoming birds. The recirculation system generally includes conduits 24 and 26, with a heat exchanger 28 therebetween, with a pump 30 moving the liquid from the chiller tank through the heat exchanger.

[0025]As shown in FIG. 2, the auger 32 extends along the bottom wall of the tank and includes its main segment of auger bl...

Abstract

An auger chiller (10) includes a carcass delivery end (18) that is sloped upwardly with a reduced radius. The auger (32) includes a progressively reduced radius auger segment (38) that matches the configuration of the angled section of the chiller tank, with the pitch of the auger blade being greater in this section of the tank for advancing the birds more reliably in a first-in first-out delivery to a sloped bird unloader (46). An arcuate basin (50) is formed at the lower arc of the peripheral rim wall (48) of the bird unloader, assuring that the heavier birds tend to sink into the basin, tending not to return to the chiller tank.

Description

FIELD OF THE INVENTION[0001]This invention generally relates to a poultry chiller for reducing the temperature of whole birds after the birds have been eviscerated on a poultry processing line. More particularly, the invention relates to an auger chiller with a sloped bird unloader that retrieves the chilled birds from the delivery end of a chiller tank.BACKGROUND OF THE INVENTION[0002]In the processing of poultry, it is desirable to reduce the temperature of the birds after the birds have been processed, such as after the birds have been de-feathered and eviscerated and are otherwise oven-ready, and before the birds are packaged for delivery to the customers.[0003]One type of poultry chiller is the auger-type chiller that includes an elongated, semi-cylindrical open top tank having an auger placed therein. Cold water is placed in the bird delivery end of the tank and moved to the bird entrance end and the water is recirculated through a cooling system such as a refrigeration system...
