A meat separator separates meat part attached to bone part by coming into contact with outer peripheral surface of the bone part of bone-in meat that moves relatively with respect to the meat separator. The meat separator includes a plurality of clamp blocks. The clamp blocks each include scraping contact portion that comes into contact with the outer peripheral surface of the bone part, and the scraping contact portions cooperate with each other so as to clamp the outer peripheral surface of the bone part. At least one of the clamp blocks is configured so that at least a part of the scraping contact portion of the clamp block is displaceable in a plurality of directions along outer surface shape of the bone part, and the at least one of the clamp blocks includes biasing function portion that elastically pushes back the displacement in direction moving away from bone part.

A poultry leg meat deboning device is configured to perform a separation of a meat part from a femur with respect to a poultry leg meat to which a peeling off of the meat part has been performed until a side of a knee joint of the femur in a bone-in poultry leg meat which has been cut from a femur of a poultry carcass. The poultry leg meat deboning device includes: an ankle holding part configured to hold an ankle of the poultry leg meat.

A shoulder incision-making apparatus for a poultry carcass according to the present invention is for cutting a shoulder joint section of a poultry carcass, and includes: a fixing jig on which a poultry carcass which is eviscerated and which has leg parts removed is to be placed and fixed; a conveyer forming a conveyance path of the fixing jig and configured to convey the fixing jig along the conveyance path; a first cutter disposed in the conveyance path; and a second cutter disposed in the conveyance path at a downstream side of the first cutter in a conveying direction. The first cutter is configured to make an incision on the shoulder joint section of the poultry carcass, and the second cutter is configured to be inserted into the incision to cut the shoulder joint section.

Incision making apparatus and incision making method

A shoulder-blade incision-making apparatus is provided and includes: a fixing jig on which the poultry carcass which is eviscerated and which has leg parts removed is to be placed and fixed; a fixing jig conveyer forming a conveyance path of the fixing jig and convey the fixing jig along the conveyance path; a first separating member disposed above the conveyance path movably upward and downward; and a first driving device for moving the first separating member in an upward and downward direction. The first driving device is operated to move downward the first separating member and move the first separating member along a surface of the shoulder blade of the poultry carcass in accordance with a timing when the poultry carcass fixed to the fixing jig reaches a meat-separation position below the first separating member, therefore the meat portion attached to the shoulder blade is separated from the shoulder blade.

Shoulder-blade incision-making apparatus

A contour measurement apparatus and a contour measurement method for measuring a contour of a poultry carcass, and a deboning device for a poultry carcass are provided. The contour measurement apparatus includes: a fixing jig on which the poultry carcass is placed and fixed; a conveyer forming a conveyance path for conveying the fixing jig; a contact element being supported movably in an upper and lower direction within a two-dimensional plane, and being able to be in contact with a measurement target portion of the poultry carcass; an upper and lower direction position sensor for detecting a position of the contact element in the upper and lower direction; a fixing jig position sensor for detecting a position of the fixing jig moving in a conveying direction; and a contour calculation unit for calculating a contour of a surface of the poultry carcass on the two-dimensional plane based on detected values.

A poultry tenderloin extraction apparatus is provided that can achieve higher poultry tenderloin extracting process performance without posing a risk of bone chips mixing in the poultry tenderloin. The poultry tenderloin extraction apparatus includes: a fixing jig configured to move while holding a poultry carcass; a poultry tenderloin extraction body section disposed on each of left and right sides with respect to a conveying direction of the fixing jig; a first moving unit configured to move the poultry tenderloin extraction body section toward the moving fixing jig; and a second moving unit configured to move the poultry tenderloin extraction body section away from the moving fixing jig. The poultry tenderloin extraction body section includes a clamping device including: a clamping lower plate to be inserted under the poultry tenderloin in a width direction relative to a longitudinal direction of the poultry tenderloin of the poultry carcass held by the fixing jig; and a clamping upper plate to be supported above the poultry tenderloin, the clamping device being configured to clamp the poultry tenderloin between the clamping lower plate and the clamping upper plate when the poultry tenderloin extraction body section moves toward the fixing jig. The apparatus is configured to, while the poultry tenderloin is clamped between the clamping lower plate and the clamping upper plate, separate the poultry tenderloin from the poultry carcass by a movement of the fixing jig toward a front side in the conveying direction and a movement of the poultry tenderloin extraction body section away from the fixing jig by the second moving unit.
