A machine for the continuous marination of meat products massages the meat pieces in marinade and the marinade in contact with the meat pieces at all times during the marinating process. The apparatus includes a rotating cylndircial drum (12) made from a series of adjacent longitudnal, sawtooth-shaped internal vanes (14). The vanes (14) are segmented by longitudinally spaced dividers (20) forming compartments (22) in the drum (12), with periodic transfer sections to urge the meat and marinade mixture from one compartment to the next as the drum is rotated. The drum may be rotated in one direction for approximately one revolution at a high RPM, and then stopped and rotated in the other direction.
