JPH057451A - Dressing of frozen fish - Google Patents

Abstract

PURPOSE:To simplify the work for the dressing of a cut block of a frozen fish and to improve the production efficiency. CONSTITUTION:A block x is clamped from above and below with a comb-shaped cutting guide 1 and laterally cut with a band saw 4. The cutting is stopped immediately before the base of the comb tooth of the guide 1 to leave middle bones Y and small bones y as they are. The cutting direction of the block x is changed and the block is cut by the same means to cut the block in the direction of thickness until the saw is passed through the opposite end. The remaining middle bones Y and the small bones y are removed to complete the dressing operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing sausage of frozen fish such as frozen tuna.

[0002]

2. Description of the Related Art In a frozen tuna processing factory or the like, the fish is supplied with its internal organs cut and its tail already cut, and the head A is cut there (as shown in FIG. 5 (a)). The dash-dotted line a) is carried out. Then, as shown in FIG. 2B, after dorsoventral cutting is performed along the midbone Y by cutting from the side of the fish X (dashed line b), as shown in FIG. It is split left and right along the bones Y (one-dot chain line c), and then cut into a plurality of pieces in the length direction (one-dot chain line d, hereinafter referred to as length cut), as shown in FIG. It is taken out as a plurality of blocks x.

[0003] In these blocks x, after peeling or the like has been performed, as shown in Fig. 6, removal of the middle bones Y and small bones y (dashed lines e and f) and cutting of fins (dashed line g).
And after removing the blood-stained portion (dashed-dotted line h), it is sent to sacrifice processing or the like.

In this sacrifice processing, as shown in FIG. 7, a width cut (solid line i) and a thickness cut (solid line j) are performed by cutting in the direction perpendicular to the cut surface Z of the length cut. , The individual cut pieces are taken out as saku.

[0005]

However, the cutting and removing processes described so far have been performed by human labor so far, and the number of man-hours is large, so that there are many problems in terms of production efficiency and the like.

The present invention was devised in view of the above problems of the prior art, and improves the process until each block is processed to remove scraps to reduce the number of steps and improve the production efficiency. It is something to do.

[0007]

Therefore, the frozen fish sachet processing method of the present invention is provided with a cut surface (a dorsal abdominal cut surface or a left-right cut surface) in which a cut portion for width cutting and / or thickness cutting is torn along the mid bone. Make a cut so that it does not reach the cut surface, etc., and leave the cut surface part in an I shape (for example, the middle bone Y
The basic feature is to leave the small bones y portion and L-shaped (for example, leave the middle bone Y, the small bones y portion, and the blood joining portion).

When performing the above-described cutting processing, FIG.
As shown in (a), the block x is clamped by the guide 1 by using a comb-shaped cutting guide, and the width and / or the thickness is cut by cutting just before the root of the comb tooth of the guide 1. If the cutting surface portion that is cut along the middle bone is left in the I-shape or the L-shape, the cutting process can be performed easily and surely.

Further, as shown in FIG. 2B, the edge of the block x is clamped by an L-shaped clamp body 10 (or an I-shaped clamp body may be used) and cut into just before the clamp body 10. The width cutting and / or the thickness cutting may be performed, and processing may be performed so as to leave the cut surface portion cut along the midrib in an L shape (may be an I shape).

[0010]

According to the above-described processing method, pre-processing work such as removal of medium and small bones, cutting of fins and removal of blood clots, etc., which is performed on the block x before the sacrifice processing is reduced, which is efficient. Various processing can be performed. Also, middle bone Y and small bone y
By leaving the portion of, the shape of the block x at the time of cutting is prevented from being deformed, and the cutting process can be performed accurately.

[0011]

EXAMPLES Specific examples of the method of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 2 is a process diagram showing the procedure of a method for processing frozen salmon tuna according to one embodiment of the present invention, in which x represents a fish cutting block of the tuna and Y represents a midrib. There is.

At the frozen tuna processing plant, a series of processing operations such as the dorsal-ventral cutting, the left-right cutting, and the length cutting as described above are completed, and the fish body X of the frozen tuna obtained as a block x is first shown in FIG.
Peeling is performed as in (a). Next, as shown in FIG. 3 (a), a band saw for winding and rotating the pulleys 3a and 3b provided on the upper and lower sides of the base 2 and performing a cutting process on a portion extending in the vertical direction. It is sent to a cutting machine having 4 and width-cutting for scraping is performed as shown in FIG. 2 (b).

At this time, a plan view of this cutting machine is shown in FIG.
As shown in (b), the length cut surface of the block x is clamped from above and below by a comb-shaped cutting guide 1 and set in the above cutting machine. The clamped block x is reciprocally moved and returned toward the band saw 4 in the direction of the arrow in the drawing by the air cylinder 5 set in the handling device of the cutting machine to perform width cutting. At this time, stop cutting with the band saw 4 just before the root of the tooth of the cutting guide 1,
By returning it, it is possible to prevent cutting into the small bone portion y, and after the width cutting is completed, the block x is discharged as it is.

Next, the cutting direction of the block x is changed and the thickness cutting shown in FIG. 2C is performed by the same procedure. At this time, the block x is cut into the band saw 4 to the end including the blood-staining portion as shown in FIG. 4 so as not to leave an uncut portion (when the L-shaped portion is left, the uncut portion is left uncut). Only Saku is cut off by leaving a little).

After this thickness cutting is completed, the uncut portions of the middle bones Y and small bones y are taken out while being removed, whereby the scraping work is completed. Since each cutting width of the block x by this cutting machine is determined by the comb tooth pitch of the cutting guide 1, several kinds of cutting guides 1 having different pitches may be prepared.

[0017]

EFFECTS OF THE INVENTION According to the method for removing frozen fish by the method of the present invention, which has been described in detail above, removal of medium and small bones, cutting of fins and / or blood clots, which are performed on the block prior to the removing process. The number of man-hours required for pretreatment work such as removal can be reduced, and production efficiency can be improved.
If the middle bones and small bones are left, the cutting process can be performed without causing the block to lose its shape during the next width cutting or thickness cutting.
