Abstract: The objective of the present invention is to reduce a meshing seal line length and further reduce a blowhole area. A compression side blowhole B2 is generated in a region surrounded by a male rotor side blowhole contour R1, a female rotor side blowhole contour R2, and a lower cusp line k2.

Abstract: An apparatus is disclosed for left/right determination of the arm part of a pig carcass before it is deboned. A plurality of clampers move around on an endless track. At a suspension station, a work is suspended from each clamper. There are left/right and front/back determination stations where it is determined whether a left-side or right side, and a front-side portion or back-side portion is facing a side irradiated by X-rays. Based on results of the determinations, posture of the work is corrected by a clamper rotating device. At an X-ray imaging station, it is controlled so that the front-side portion of the work faces the side irradiated by the X-rays and a longer side faces a movement direction of the endless track. An X-ray image of the work is obtained to determine a target coordinate of a bone-part surface required for incision making and deboning processes.

The system includes a cooling device (3) which generates cold with an air cycle in which air is used as a refrigerant, a freeze-drying chamber (2) accommodating a heat exchange unit which causes heat exchange between the refrigerant and the object, and a control unit (11) which controls a cooling capacity of the cooling device. The control unit adjusts the temperature in the freeze-drying chamber to a predetermined target temperature by controlling an amount of the cold generated in the cooling device.

Abstract: In a deboning process, a knee joint length is measured in a work loading section of a first process station, and incision making of a thigh meat portion is performed in a second process station based on the measured knee joint length. At the same time, the entire length of a work is measured, and the knee joint length is calculated from previously collected data based on the measured entire length of the work. Positioning of a cutting blade and a meat separator is performed based on these values in subsequent process stations, and cutting of a tendon adhering to a knee joint and tearing of thigh meat are performed. A thigh bone is separated from a lower thigh in a further process station.
