Description

[Detailed description of the invention]

The present invention relates to a belt-shaped cutter that is used to cut away meat and bones in the form of a single knife when processing old animals such as birds and animals. Conventionally, the bones are separated from the meat for ~ 7) Deboning 4 to 1 In general, the cut f'15 is made with a small force and the φ11 is pulled by hand, and 14 pieces of large-sized household baths are removed. In this case, wrap a strong, thick thread around the bone and let it slide along the bone. Ru. Since such deboning work requires a great deal of effort, many attempts have been made to reduce the force by 1 time and improve work efficiency by using power cutters, etc. As a technical feature of the work, bones, which are the thorny objects, are not geometric in shape;
In particular, symptoms occur in the IQ, 1 segment, which is intricately connected to ligaments and cartilage, so if a sharp duJ force blade's proboscis is used, it will dig into the bone, and the cut pieces will be edible. It is left attached to the meat and then taken away. Because of these technical difficulties, a tool for high-grid scales that is suitable for deboning has not yet been developed. The present invention was made in view of the above circumstances, and there is no risk of cutting into a single layer of bone, and the meat and bone can be easily separated with high efficiency while sliding along irregularly shaped bones. [12] This cutter can be used as a hand tool (7), and can also be used as a moving knife. This method takes advantage of the fact that if the cutter is configured with a cutter, there is a high risk of cutting into the bone.Also, even if the material is hard, it will cut into the bone if the difference in hardness between the cutter and the bone is small. In order to achieve the above object based on this principle, we have invented a belt edge made of synthetic resin. %I is made into an acute angle, and the edge forming the blade described in 1- is provided with a continuous 1.'f?: uneven surface.Next, 1'- of the present invention. The μ example is shown in Figure 1.

The hard polyurethane of is harder than flesh and lungs, but softer than bone. A belt-shaped cutter is used to perform the deboning work, and the belt 1 is cut in front of the bones 4 and 11 attached to the meat mass (not shown in Figure 7). Kake 1 Ryo prostitute A. Hold B in both hands and move the arrows a and b (if you move back and forth alternately like D, the blade 2 will rest on the bone 1c) and slide to separate the bone and flesh τ . As the belt 1 is cut along the bone in the direction of arrow C, the hardness of the hard protruding bone of the hard polyurethane that is the material of the belt 1 is lower than that of the hard protruding bone, and in addition, the hard polyurethane Fi has some flexibility. Since the blade 2 has an unevenness 3, it is possible to separate the bone and meat by 17] while following the contour of the joint 4a of the bone 4. It is possible to easily remove lungs that are stuck to the joints 4a, etc. Figure 2 shows examples of various types of unevenness provided on the blade. ))of,

It may be triangular like a barrel or arcuate like f'fc (G in the same figure). Since the belt 1 of this embodiment is made of hard polyurethane, it is very safe because even when the belt 1 has blades 2 formed on its edges (17), there is no odor or sharp edges that could cut your fingers.
