The edible bird carcass scissors muscle insertion device of Patent Document 1 has a problem that the muscles cannot be inserted into the scissors from a predetermined position near the clavicle to the side end of the cervical spine, which is closer to the bevel than the clavicle. In the device of Patent Document 1, when the muscle insertion start position was moved to the cervical spine side and the muscle was inserted from the cervical spine side end to the bevel side end, the clavicle was cut and cut by the muscle insertion device immediately after the start of muscle insertion. The clavicle is pushed by the scissors muscle insertion device and bites into the scissors, causing the problem that the meat quality of the scissors deteriorates.
The present invention has been made in view of the above problems, and is a holding member that fits into the thoracic cavity of the upper half of the flesh steak with chicken fillet to hold the upper half of the flesh steak with chicken fillet, and a flesh steak with chicken fillet. A poultry carcass scissors muscle insertion device equipped with a pair of muscle insertion mechanisms that approach the upper half of the carcass from both sides and insert muscles into the chicken from the side. It is an object of the present invention to provide a poultry carcass meat meat muscle insertion device that can be muscled into the chicken meat and does not cause deterioration of the meat quality of the chicken meat due to the clavicle biting into the chicken meat.

In order to solve the above problems, in the present invention, a holding member having a fitting portion that fits internally into the thoracic cavity of the upper half of the flesh steak with chicken fillet and holding the upper half of the flesh steak with chicken fillet, and chicken fillet. A pair of first muscles that approach the upper half of the flesh steak from both sides and are closer to the flank steak than the clavicle and from the first predetermined position near the clavicle to the side end of the cervical spine. Approaching the mechanism and the upper half of the chicken carcass with chicken from both sides, closer to the bean steak than the first predetermined position, and from the second predetermined position near the bean to the side end of the bean, the chicken is squeezed from the side. A pair of second muscle insertion mechanism and a third predetermined position closer to the thoracic bone than the first predetermined position closer to the flank steak than the second predetermined position closer to the upper half of the chicken carcass with chicken fillet from both sides. It is provided with a pair of third muscle insertion mechanisms for inserting muscles into the chicken from the side up to the fourth predetermined position, and is characterized in that the first muscle insertion mechanism, the second muscle insertion mechanism, and the third muscle insertion mechanism operate in this order. Provided is a poultry carcass chicken fillet muscle insertion device.
The first muscle insertion mechanism is closer to the bevel than the clavicle and the muscle is inserted from the first predetermined position near the clavicle to the side end of the cervical spine, and the second muscle insertion mechanism is closer to the beard than the first predetermined position and near the beard. 2 Stroke from the predetermined position to the end on the bevel side, and the third muscle insertion mechanism inserts the muscle from the third predetermined position closer to the clavicle than the first predetermined position to the fourth predetermined position closer to the bevel than the second predetermined position. This allows the chicken to be muscled from the cervical spine side end to the bevel side end. Even if the clavicle is cut by the first muscle insertion mechanism at the end of the muscle insertion from the first predetermined position near the clavicle to the vertebral side end, which is closer to the clavicle than the clavicle, the first muscle insertion mechanism is the cut clavicle. Since it pushes up and does not press against the clavicle, the clavicle is not damaged and the meat quality does not deteriorate.

In the poultry carcass scissors muscle insertion device according to the present embodiment, the first muscle insertion mechanism 3a is closer to the bevel 100c than the clavicle and the muscle is inserted from the first predetermined position near the clavicle 100b to the end of the cervical spine 100g. The second muscle insertion mechanism 3b is closer to the bevel than the first predetermined position, and the muscle is inserted from the second predetermined position near the bean 100c to the end of the bean 100c, and the third muscle insertion mechanism 3c is the clavicle from the first predetermined position. Since the muscle is inserted from the third predetermined position closer to 100 g to the fourth predetermined position closer to the bevel 100c than the second predetermined position, it is possible to insert the muscle into the scissors 100a from the cervical spine 100 g side end to the bean 100c side end. Even if the clavicle 100b is cut by _{the knife 3a 1} of the first muscle insertion mechanism 3a at the end of the muscle insertion from the first predetermined position to the end of the cervical spine 100 g _{, the knife 3a 1} pushes up the cut clavicle 100b and scissors. Since it is not pressed against the 100a, the scissors 100a are not damaged and the meat quality is not deteriorated.
When the scissors 100a is inserted into the cervical spine side end, the scissors 100a is firmly connected to the sternum 100f in order to surely cut the connection between the tendon and the coracoid bone at the cervical spine side end of the scissors 100a. It is desirable to add muscle to the lateral end of the cervical spine.
When the chicken fillet 100a is muscled to the bean side end, the membrane tissue covering the chicken is pushed by the knife of the muscle insertion mechanism and gathers at the bean side end to form a streak. In order to surely cut the connection portion between the streak and the sternum, it is desirable to insert the bevel 100c side end in a state where the scissors 100a is firmly connected to the sternum 100f.
In the poultry carcass scissors muscle insertion device according to this embodiment, the cervical vertebra 100g side end of the scissors 100a is muscled with the central portion of the scissors 100a in the longitudinal direction and the bean 100c side end connected to the sternum 100f. Since the central portion of the scissors 100a in the longitudinal direction is connected to the sternum 100f, the ends of the scissors 100a on the bevel 100c side are muscularized. Can be squeezed. Since the cervical spine 100g side end is muscled with the connection length between the scissors 100a and the sternum 100f being long before the bevel 100c side end, it is stronger than the streak connection part at the bevel side end. The tendon connection at the 100 g side end of the cervical spine can be reliably cut.
In order to firmly support the scissors 100a with the sternum 100f and to streak both ends of the scissors 100a in the longitudinal direction, the length of the streaks at the center of the scissors by the third streak mechanism 3c is determined by the first streak mechanism 3a, It is desirable that the length is longer than the length of the muscles at both ends of the scissors by the second muscle insertion mechanism 3b.
If the length of one muscle insertion is large, the portion of the chicken fillet 100a that has been muscle-inserted may move unstablely and interfere with the knife of the muscle-insertion mechanism to be damaged during the muscle insertion work. By dividing the chicken fillet 100a into three parts in the length direction and inserting the muscles, the length of one muscle insertion can be shortened, unstable movement of the muscled portion can be suppressed, and damage to the chicken fillet 100a can be prevented.
