Abstract
A method for gaining the remaining meat from the bones of cutlet strings or racks and a separating apparatus for carrying out this method are described. The separating apparatus essentially comprises a hollow drum (1) having a perforated outer surface (7), on which a compression belt (2) partially wrapped around said drum (1) is held under pressure. The hollow drum (1) includes a groove (8) in its central region which extends radially and around said drum and comprises perforated limiting faces. The cross-section of the groove (8) essentially corresponds to that of the bone string to be processed.
Claims18
A method for gaining remaining meat from bone by feeding said bone through a recessed compression zone formed between a perforated supporting surface and an elastic compression element, such that said bone is substantially positioned in said recess;
- and
- directing pressure in said compression zone on only portions of said bone that have attached meat to separate the attached meat from the bone and cause the separated meat to flow away from the bone through said perforated supporting surface.
A method for gaining remaining meat attached to bone strings of cutlet strings or racks of slaughtered warm-blooded animals by feeding said bone strings through a compression zone having a recess formed between a perforated supporting surface and an elastic compression element, such that said bone strings lie in said recess;
- and
- directing pressure on only those portions of said bone strings which carry remaining meat, so as to cause said meat to flow away from said bone wherein the gaining of said remaining meat occurs on feeding and passing said bone string through said compression zone continuously.
A separating apparatus for gaining remaining meat from bone strings of cutlet strings or racks of slaughtered warm-blooded animals, in particular pigs, by compressing such bone strings in a compression zone between a perforated supporting surface and an elastic compression element, whereby a quasi hydraulic pressure is exerted only on those parts of said bone string carrying remaining meat in said compression zone, said apparatus comprising:
- a) rotatably driven hollow drum means open on one side and having a perforated outer drum surface;
- b) compression means arranged along a part of said outer drum surface;
- c) endless elastic compression belt means defining an outer belt surface which is wrapped around a portion of the circumference of said hollow drum means and guided such that it forms a draw-in wedge for said material to be compressed and said compression zone in the region of said compression means;
- d) clearing means adapted to be located inside said hollow drum means;
- and
- e) scraping means associated with said outer drum surface,
- wherein said hollow drum means comprise groove-like channel means which interrupt said outer drum surface by extending radially and around the same, the cross-section of said channel means corresponding essentially to the cross-section of the bone strings of the cutlet strings to be processed.
