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.
