Abstract
A poultry leg meat slit-forming device includes: an ankle holding part configured to hold an ankle of bone-in poultry leg meat cut from a femur of a poultry carcass; a blade unit having a slit-forming blade; an inserting driving part configured to drive the blade unit such that an blade tip of the slit-forming blade is inserted into the poultry leg meat along an opposite side with respect to a kneecap in a tibia among the poultry leg meat held on the ankle holding part; and a leg meat pressing part configured to elastically press a surface of the poultry leg meat from a side of the kneecap.

A poultry leg meat slit-forming device comprising:
- an ankle holding part configured to hold an ankle of bone-in poultry leg meat cut from a femur of a poultry carcass;
- a blade unit having a slit-forming blade;
- an inserting driving part configured to drive the blade unit such that an blade tip of the slit-forming blade is inserted into the poultry leg meat along an opposite side with respect to a kneecap in a tibia among the poultry leg meat held on the ankle holding part;
- a leg meat pressing part configured to elastically press a surface of the poultry leg meat from a side of the kneecap;
- and
- a moving part configured to move at least one of the ankle holding part and the blade unit with respect to the other one such that the slit-forming blade makes a slit-forming movement in an extending direction of the poultry leg meat held by the ankle holding part, wherein
- the blade unit comprises:
- a blade holding part that is configured to hold the slit-forming blade such that a blade edge of the slit-forming blade faces a side opposite with respect to the ankle holding part in a direction of the slit-forming movement of the slit-forming blade and that is configured to hold the slit-forming blade so as to be displaceable in a front surface/back surface direction of the slit-forming blade;
- and
- a biasing part configured to elastically bias the slit-forming blade toward a bone of the poultry leg meat in the front surface/back surface direction of the slit-forming blade.
A poultry leg meat automatic slit-forming method comprising:
- an ankle holding process of holding an ankle of bone-in poultry leg meat cut from a femur of a poultry carcass;
- a blade inserting process of inserting a blade tip of a slit-forming blade into the poultry leg meat along an opposite side with respect to a kneecap in a tibia among the poultry leg meat and so that the blade tip of the slit-forming blade does not pass through the poultry leg meat at a vicinity of the ankle of the poultry leg meat;
- a pressing process of elastically pressing a surface of the poultry leg meat from a side of the kneecap after the blade inserting process;
- and
- a slit-forming process of performing a slit-forming along a bone of the poultry leg meat by making the slit-forming blade to perform a slit-forming movement in a straight line until a femur head of the poultry leg meat in a state in which the pressing process is continued, wherein
- in the blade inserting process and the slit-forming process, the slit-forming blade is elastically biased such that a flat portion of the slit-forming blade faces toward the bone.
