US Patent 9295270 Rocker chiller with central and side deflectors

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.
