In an auger-type product chiller having an auger including a series of successive flights that form a generally helical structure that, when rotated, moves product through cold water for chilling the product, control elements extending from faces of the flights at a non-zero angle. The control structures prevent "clumping" and packing of poultry product, break up any "clumps" and packs of the product that may develop, and improve product uniformity. In this manner, the advantages of proper agitation, as well as rapid, predictable and even product cooling and moisture introduction, are achieved. Implementations of the control elements include sets of rods extending from the flights at 30.degree. angles from radial lines of affixation to the flights, flat plates extending from the flights at 30.degree. angles from radial lines of affixation to the flights, and sets of rods extending between successive flights near peripheries of the flights.
