Apparatus for macerating meat
 An apparatus for macerating meat-type products includes a pair of counterrotating shafts, each of which contains a one-piece arbor having an integral assembly of alternating radially projecting and axially extending teeth members and spacer members. A plurality of open channels are defined by the spacer members disposed between adjacent radially projecting teeth members. Each of the teeth members has a peripheral outer edge which penetrates the products passing through the counterrotating arbors in the axial plane.
