Apparatus for separating meat from bones

Abstract

An apparatus for severing the meat adhering on bones from these bones, in particular for poultry parts such as carcasses of chickens or turkeys, has a press comprising a press cavity into which the mass of meat and bones is introduced between a press piston and a counter-piston. The wall of the press cavity is, at least within the area of the counter-piston, formed of a perforated filter. The counter-piston has a closing section for a discharge opening for discharging the pressed bones from the press cavity and said closing section has a greater diameter than is the diameter of the press cavity and said counter-piston having a filter section equally formed of a perforated filter and having a smaller diameter than is the diameter of the press cavity. In closing position of the counter-piston, the filter section of the counter piston having over the length of its perforated filter the same external diameter is located at a distance from the wall, formed of a perforated filter, of the press cavity, so that an annular space is formed. The meat having been brought to a pasty condition under the action of the press pressure passes through the holes of the perforated filter forming the wall of the press cavity and through the holes of the perforated filter forming the filter section of the counter-piston, whereas the bones are retained. These bones are discharged during a movement of the counter-piston directed away from the press piston via the thus released discharge opening.
