1. An apparatus for preparing a particulate, proteinaceous product from raw protein-comprising animal parts, the apparatus comprising:

  • mulling means for converting the raw animal parts to ground animal parts, said mulling means having an inlet through which raw animal parts to be ground may be introduced and an outlet through which ground animal parts may be discharged;

    hydrolyzing means adapted for enzymatically hydrolyzing proteins in the ground animal parts to form an aqueous suspension of partially hydrolyzed animal parts, said hydrolyzing means having an inlet through which the ground animal parts may be introduced and an outlet through which the aqueous suspension may be discharged;

    separating means for removing non-digestible solids from the aqueous suspension of partially hydrolyzed animal parts, said separating means having an inlet through which the aqueous suspension may be introduced and an outlet through which the aqueous suspension, from which the non-digestible solids have been removed, may be discharged;

    oil-addition means coupled to the outlet of said separating means for adding oil to the aqueous suspension passing through the outlet of said separating means, thereby forming a protein-oil suspension;

    concentrating means for partially dehydrating the protein-oil suspension, thereby forming an oleaginous suspension of partially hydrolyzed protein, said concentrating means having an inlet through which the protein-oil suspension may be introduced and an outlet through which the oleaginous suspension may be discharged after passing through said concentrating means; and

    oil-removal means for removing a predetermined portion of the oil in the oleaginous suspension, thereby forming a particulate, proteinaceous product, said oil-removal means having an inlet through which the oleaginous suspension may be introduced, a first outlet through which the proteinaceous product may be discharged after passing through said oil-removal means, and a second outlet through which the predetermined portion of oil removed from the oleaginous suspension may be discharged.
