  • Patent number: 11419338
    Abstract: A cartilage cutting device for a bone-in meat according to an embodiment includes a cutting blade disposed on a conveying path for a bone-in meat and an elastic support portion for elastically supporting the cutting blade so that the cutting blade can recede by a reaction force applied to the cutting blade when cutting the bone-in meat. The elastic support portion is configured such that an elastic supporting force of the elastic support portion is switchable between a first elastic supporting force and a second elastic supporting force. The first elastic supporting force is capable of cutting a cartilage adhering to a bone part of the bone-in meat. The second elastic supporting force is smaller than the first elastic supporting force and is incapable of cutting the cartilage.
