Abstract: A rocker chiller includes a chilling tank and a baffle assembly. The baffle assembly includes a drive shaft, a baffle blade extending along a bottom of the tank and a plurality of spaced-apart and elongate baffle members extending in a radial direction from the drive shaft towards the bottom of the tank. The elongate baffle members contact the drive shaft at spaced-apart locations along the drive shaft and define a plurality of openings therebetween. The elongate baffle members are sized and shaped to push at least a majority of the carcasses laterally through the heat exchanging liquid in a direction generally orthogonal to a lengthwise forward movement of the carcasses from the first end of the tank to the second end of the tank.

Abstract: A rocker chiller includes a tank having a bottom wall and a dasher assembly, which includes an axle extending in a lengthwise direction and a dasher blade extending adjacent the bottom wall. The dasher blade is mechanically coupled to the axle by a plurality of support arms extending in a radial direction between the axle and the dasher blade. A carcass deflector is provided, which is attached to the axle so that each back-and-forth oscillation of the axle and dasher blade during operation of the rocker chiller causes a back-and-forth oscillation of the carcass deflector in unison with the back-and-forth oscillation of the axle and dasher blade. The carcass deflector is spaced longitudinally along a longitudinal axis of the axle and has a carcass deflection region therein that extends above a top surface of the axle and in a plane that is generally orthogonal to the longitudinal axis of the axle.

Abstract: An unloader paddle for use with a poultry processing device includes an elongated arm having opposite proximal and distal ends. The elongated arm proximal end is configured to be attached to a rotatable hub and a blade is secured to the elongated arm distal end. The paddle blade includes a face, a first edge portion, a second edge portion, and a third convexly curved edge portion. The second and third edge portions of the blade extend from the first edge portion and converge to form a tip region, and the tip region is angled or bent in a direction that is transverse to the face of the blade. The blade is secured to the elongated arm distal end such that the face is oriented transverse to a longitudinal direction of the elongated arm.

Abstract: A rocker chiller 10 includes a tank 12 with a dasher assembly 26 that oscillates across the curved bottom wall of the tank. A series of central deflectors 40 are positioned at intervals along the length of the tank and another series of side deflectors 46 are mounted at intervals along the upwardly extending side walls 16 and 18 of the tank. The side deflectors are offset longitudinally with respect to the central deflectors. The offset relationship of the side deflectors and central deflectors creates serpentine paths through the elongated tank on both sides of the tank that require the carcasses to move through more of the heat exchanging liquid and which reduces the tendency of carcasses passing each other.

Abstract: The rocker chiller 10 includes a semi-cylindrical tank 12 filled with heat exchanging liquid and a baffle assembly 18 that rocks back and forth across the bottom wall of the tank. The baffle 26 of the baffle assembly defines baffle openings 29 that are sized and shaped to pass the heat exchanging liquid through the openings in response to the rocking of the baffle, but small enough so that the baffle engages and retards the movement of at least some of the carcasses from moving through the baffle, thereby massaging the carcasses and increasing the moisture retained in the carcasses.

Abstract: The post chill decontamination tank assembly 24 usually is positioned at the exit end of a chiller 10 of a poultry processing line. Eviscerated birds fall into the decontamination tank 25 and the paddles 42A-42D of the paddle assembly 34 revolve in the tank about the axis 37 and collect and lift the birds through the liquid and discharge the birds from the tank. An antimicrobial is added to the liquid for treating the exposed surfaces of the birds.

Abstract: Birds are moved through chilled water by bird moving means such as an auger or by a series of paddles. The birds tend to accumulate in a predetermined path in the water. Streams of water that include an antibacterial additive are directed toward the predetermined path and engage and disperse the birds, and wash the birds with the streams of water and the antibacterial additive, thereby increasing the rate of heat transfer from the birds and increasing the effectiveness of the antibacterial properties of the agents in the chilled water.

Abstract: The chiller includes a semi-cylindrical tank (36) that conforms to the perimeter of its auger (38) so that the water can be raised to a water level (68) high above the auger shaft (44). Streams of water (84) are directed from the pulling side (80) across the lower portion of the tank beneath the auger shaft (44) to the dead side 82 of the tank at intervals along the tank so as to disperse the lower portion of the masses (23) of buoyant birds (22) from the more crowded pulling side (80) of the tank, beneath the auger shaft (44) toward the more vacant dead side (82) of the tank, thereby distributing the products more evenly throughout the tank and causing more water turbulence in the tank, thereby increasing the rate of heat transfer from the birds and avoiding having the birds cross over the auger shaft moving backward in chiller into a following flight of the auger.

Abstract: A poultry chiller 100 has a hanger 140 suspended from the upper portion of the tank 102 that supports the bearing block 160 of the auger shaft 112 between the auger blades. A conical bird deflector 175 is mounted on the auger shaft and radially deflects the birds away from the bearing block as the birds are urged across the bearing block.

Abstract: A chiller for reducing the temperature of previously eviscerated whole birds and the like, includes a tank having a bird outlet end, a bird inlet end, an inlet end plate, an outlet end plate, and a water reservoir between the ends. The poultry chiller also includes water circulation means for introducing water into the reservoir at the bird outlet end of the tank, draining water at the bird inlet end of the tank, and forming a movement of water generally from the bird outlet end toward the bird inlet end of the tank. The chiller further includes a motive device for urging the birds from the bird inlet end to the bird outlet end of the tank, the motive device being in driven relationship with a power means. A transverse wall having a lower portion, a central portion, and a top edge, is disposed at the bird inlet end of the tank substantially parallel to the inlet end plate such that a sump is formed between the lower portion of the transverse wall and the inlet end plate.
