Fecha de publicación: 09/01/1979 Fuente: WIPO "meat" An apparatus for tenderizing meat by subjecting the meat fibres to compressive and impact forces, comprising a pair of driven rollers mounted in a frame, between which the meat is fed by a conveyor. The rollers are provided with elongate axial ribs, preferably of circular section, which alternate in the roller nip during rotation, and the rollers and the ribs are dimensioned such that the meat fibres are weakened without the meat becoming bruised. The invention is particularly applicable to the pre-treatment of ham immediately prior to brine injection.
