As the blade attachment disk (rotary disc 21) rotates, the subsequent blade 23 sequentially cuts meat from the outer side end surface toward the inner side end surface with a thickness corresponding to the depth of the U-shape. In this case, in order to cut the meat in the width direction by the previous blade 23 and cut the meat again in the state where it is partially overlapped in the radial direction by the next blade 23, the size of the meat to be cut out in the width direction is consequently increased. The width is cut to be smaller than the width of the cutting edge of the blade 23 (for example, about 1/2 of the width of the U-shape).

First, a meat chunk B (not shown) in a frozen state or a thawed state is placed in the meat chunk supply space S formed by the guide member 31 in a state where the rotation of the blade attachment disk (rotating disc 21) is stopped, Lightly press the lever 35 of the supply member from above. In this state, the drive motor 17 is rotated to rotate the blade mounting plate (rotary disc 21) in the direction of arrow A in FIG. As the blade attachment disc (rotary disc 21) rotates, the outermost blade 23 first bites at the end of the meat, and the meat having a U-shaped cross section causes the meat to reach a predetermined depth. , Cut by width.

Since it is pressed against the cutting member 41 by the
Meat is pressed between the plate-shaped blades 45 of No. 1, while the blade mounting board (rotary disc 21) continues to rotate, so that the plate-shaped blades 45 cut the meat into small pieces.

In this case, since the first blade 23 and the second blade 23 partially overlap each other in the direction intersecting the rotation direction, the portion cut by the second blade 23 is the size of the second blade 23 itself. The cutting width is the non-overlapping area. In addition, since the cutting depth is set to be the same for all the blades 23, the meat is cut by a predetermined width while being cut at the same depth from the end face.

る。Further, the blade mounting board of the present invention may be a reciprocating plate member instead of the above-mentioned disc. When the reciprocating member is used as described above, the blade 23 is attached along a virtual line in a direction intersecting the moving direction so that a new portion of the blade sequentially hits the meat chunk by the movement of the blade attaching plate. Moreover, it is preferable that the blades are connected or partially overlapped when viewed in the moving direction. By doing so, as the blade attachment plate is reciprocated, the meat is sequentially cut from the end face with a predetermined width in the forward path or the return path. A cutting member is provided below the reciprocating type blade attachment board, and like the above-mentioned example, the end of the meat being cut out by the blade of the blade attachment board is a member for attaching the blade. A piece of meat is cut by pushing it into a large number of plate-shaped blades that are provided on the side opposite to the supply side of the blade attachment board in the direction of movement by the surface part on the side opposite to the supply side of the blade attachment board, and cutting in the width direction. Is obtained.
