Abstract: A device for severing the meat adhering to bones from these bones has a press cavity provided with a press piston and a counter-piston, the mass of meat and bones introduced into the press cavity being pressed between said both pistons. Passage openings formed of a perforated filter are provided in the wall of the press cavity, noting that the meat having been brought into the pasty condition by the press pressure can pass through this openings, whereas the bones are retained. Both pistons have cylindrical sections and can be shifted in axial direction of the press cavity within this press cavity. The dimensions of the pistons are, as seen in radial direction, smaller than that of the press cavity. Both pistons have blunt, preferably slightly bomb-shaped front surfaces. One of the pistons releases during its retracting movement a discharge opening for discharging the pressed bones out of the press cavity.
