Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is a cutter for cutting fish flakes, which is used when cutting large quantities of fish flakes such as bonito flakes and mackerel flakes in a factory.

(Prior art) It is desirable that bonito flakes be as thin as possible and uniform in thickness and shape in terms of the quality of the soup stock when used in cooking and the texture when eaten.

Recently, kerifobushi is being packaged in several grams (the amount that is consumed at one time in a typical household), but in this case, the kerifobushi must be uniform in shape, size, thickness, etc., because weighing is a filling operation. It is hoped that

In this case, it is desirable that the once cut bonito flakes be of a size that can be immediately packaged in bags without the need for secondary processing. If the cut bonito flakes can be packaged as is, the time the bonito flakes are exposed to the air will be shortened, making it difficult for the bonito flakes to oxidize, and the flavor of the bonito flakes will be lost.

In addition, in order to prevent the flavor of the dried bonito flakes from being impaired, it is necessary to minimize the frictional heat generated during cutting of the dried bonito flakes.

Conventionally, there have been cutting devices of this type as shown in FIGS. 1 and 2.

The cutting device shown in FIG. 1 has a planer blade c attached to a cutting table a, and the cutting device shown in FIG. 2 has a planer blade c attached to a rotary plate b.

To cut fish flakes d with the cutting device shown in Figure 1, fish flakes d are pressed against planer blade c and moved back and forth, and to cut fish flakes d with the cutting device shown in Figure 2, the rotating plate is rotated. Rotate the planer blade c and press the fish flakes d against the planer blade c.

Also, conventionally, like the cutlery of Utility Model No. 53-69482,
A blade whose shape is curved in the circumferential direction of a cylindrical base material, or a plurality of plate-shaped blades with intermittent blades, such as the blade of Utility Model Publication No. 47-41392, are attached to one rotating disk. There was also one in which the arrangement of the intermittent blades of the plurality of plate-shaped blades was shifted.

There was also a bonito flaking machine like the one shown in Jitsugan No. 11028-1973.

(Problems to be Solved by the Invention) Since the cutting devices shown in FIGS. 1 and 2 use a planer blade c, they have the following problems.

It is easy for shavings and cutting powder to become clogged between the planer blade c and the rotary plate b to which it is attached. Moreover, since the thickness of the keratin knots differs before and after they are clogged, it is not possible to obtain keratin knots with a constant thickness. In addition, if the kerifubushi becomes clogged, the blade becomes dull and unreasonable force is applied to the blade, causing it to break.
The rotating plate becomes distorted, and as a result, the thickness and shape of the cut joints become increasingly uneven.

Clogged bonito flakes are unhygienic, and especially in a hot and humid work environment during the rainy season, this can cause bacterial growth, which is unfavorable in terms of food hygiene.

Planer blades C have high cutting resistance and are subject to severe wear, and even carbide blades wear out in about three days in factories that mass-produce shavings. As a result, the surface of the kerifobushi loses its luster.

Since the planer blade c is subject to severe wear, the protrusion of the planer blade c must be adjusted approximately every 10 minutes in order to uniformly cut the keburu to a thickness of, for example, 2/100 mm. However, in order to do this, it is necessary to stop the cutting machine and stop the cutting operation, and in this case, the greater the number of planer blades c attached to the rotary plate, the longer the length of the planer blade c. The longer it takes, the more time it takes to adjust, resulting in a significant drop in work efficiency and productivity.

If the planer blade c is long, it is difficult to make it protrude uniformly over its entire length. In addition, if there are many blades, only one blade may protrude extremely, and in this case, the fishbushi d is strongly pressed only against that blade, and the other blades are not sufficiently pressed, reducing cutting efficiency. . Additionally, unreasonable force is inevitably applied to the extremely protruding blade, which distorts the disk, which in turn results in uneven thickness and shape of the shavings.

It takes three years of experience to be able to adjust all the planer blades uniformly, and even for an experienced person, it takes about three to five minutes on a planer with 16 blades.

Even if the person is an expert, the adjustments are made based on intuition, so there is considerable variation between different sharpeners, and even if the person making the adjustment changes, there will be variations even with the same sharpener. As a result, the thickness of kerifobushi varies, and the actual situation is that the thickness of kerifobushi currently on the market varies widely, from 2/100 mm to 10 to 100 mm.

Replacing the planer blade c takes much more time than adjusting it, and on a 16-blade sharpener it takes 15 to 20 minutes.
It takes minutes.

In addition to the above drawbacks, the cutting device shown in FIG. 2 also had the following problems.

Because the spring e presses the fish buds d against the planer blade c, the planer blade c may wear out.
When the fish section d becomes thinner due to cutting, the spring e stretches accordingly and the pressing force becomes weaker. Therefore, since the force with which the fish flakes d are pressed against the planer blade c is not always constant, even if the protrusion of the planer blade c is adjusted to be constant, the cutting will not be done to a constant thickness.

A planer blade c is used in a sharpening machine using a spring e.
Whether the cutting quality is good or bad, the fish pieces d are pressed against the planer blade c, so if the planer blade c becomes difficult to cut, the fish pieces d are forcibly cut.
As a result, not only is the force applied to the planer blade c and the wear of the planer blade c becomes even more severe,
The rotating plate may even become distorted. Therefore, it becomes increasingly difficult to cut to a constant thickness, and the cut knots turn into powder, resulting in poor yield. Furthermore, if the thickness of the dried bonito flakes is uniform, it can be weighed and filled into bags etc. accurately and in a short time, but if it is uneven, this cannot be done and the weighing process becomes troublesome. As a result, the time when the dried bonito flakes are exposed to air becomes longer, resulting in a loss of flavor.

The fish section d, which is normally pressed by the spring e, is rotated between the planer blades c and the rotating plate b.
Because they come into contact with the rotating plate d, both the rotating plate d and the rotating plate b generate frictional heat, and the rotating plate in particular has a temperature of 60°C to 80°C. As a result, the shaved bonito oxidizes, causing loss of flavor and luster, resulting in deterioration of quality.

When cut with a planer blade c, the shavings become long like a planer blade, and as they are too large to be shavings as they are, they must be pounded or kneaded to make them smaller to the same size. Not only does this work require a lot of effort, but the flavor is impaired as the bonito flakes are exposed to the air during this process, and powder is produced by pounding and kneading, resulting in poor yields.

Among the conventional technologies, in the case of the blade of Utility Model Application No. 53-69482, the blade is curved in the circumferential direction of the cylindrical base material, so the shavings cut by this rotary blade are similar to the curvature of the same blade. Similarly, it becomes curved and curly, resulting in uneven shape and thickness.
It was not in a shape that could be sold as shaved flakes, and it had almost no commercial value as shaved flakes.

Furthermore, although the cutter of Utility Model Publication No. 47-41392 has an intermittent blade, it is simply a plate-shaped cutter that is inserted into the blade insertion hole of the rotating disc.
Problems similar to those of the rotary cutter shown in FIGS. 1 and 2 were encountered.

The katsuobushi shaving machine of Jitsugan No. 11028/1977 has a helical rotary blade (spiral like the blade of a pencil sharpener), so when the katsuobushi is cut with it, the resulting shavings are similar to those of a pencil. There was a problem that the shavings would curl up into a spiral shape, making the shavings worthless as a product.

(Object of the Invention) An object of the present invention is to provide a cutter for cutting fish and fish pieces, which solves the above-mentioned problems.

(Means for Solving the Problems) As shown in FIG. 3, the cutter of the present invention has a circumferential surface 2 of a base material 1 having a circumferential surface 2. Two or more rows of protrusions 7 are formed diagonally across the ridge, and each protrusion 7 is formed with a large number of interrupted blades 3 interrupted by notches 8. In order to prevent the protrusions 7 from coming out, the intermittent blades 3 of the protrusions 7 in an appropriate row are shifted in the arrangement direction from the positions of the intermittent blades 3 of the protrusions 7 in other rows.

(Function) The knife for cutting fish joints of the present invention has a rotary shaft such as a reducer inserted into the shaft hole 6 and fixed therein, and the cutter is rotated by rotating the reducer. If the fish pieces d to be cut are brought into continuous contact as shown in FIG.

In this case, since the intermittent blades 3 of the protrusions 7 in an appropriate row are shifted in the arrangement direction from the position of the intermittent blades 3 of the protrusions 7 in other rows, the intermittent blades 3 of the protrusions 7 in each row during cutting The fish joints d do not hit at the same time, cutting resistance is low, no strain is applied to the interrupted blade 3, wear and damage of the interrupted blade 3 is small, and the sharpness is less likely to deteriorate.

In addition, if the intermittent blades 3 of the protrusions 7 in any row are not shifted in the arrangement direction, the intermittent blades 3 of the protrusions 7 in each row
Since the same part of the fish joints d is cut by cutting, parts of the fish joints d that are not touched by the interrupted blades 3 may be left uncut.
This does not occur because the intermittent blades 3 are shifted in the arrangement direction from the positions of the intermittent blades 3 of the protrusions 7 in other rows.

(Example) The cutter for cutting fish and fishes shown in FIG.
Ten or more protrusions 7 are formed on the ridge, and notches 8 are made at regular intervals at the tip of each protrusion 7 to form an interrupted blade 3.

The cutting edges of each of these intermittent blades 3 are neither helical nor curved in the circumferential direction of the base material 1, but are arranged diagonally from one end 2a in the axial direction of the base material 1 to the other end 2b. It has been done. This results in
During cutting, the fish joints d do not hit the intermittent blades 3 in each row at the same time, reducing cutting resistance and cutting the intermittent blades 3.
This is done so that you don't have to overdo it. In addition, the shavings cut by the interrupted blade 3 are not spirally rounded like pencil shavings, or curved and curled, but are flat and elongated.
The shaved knots have a uniform shape and a constant thickness, and are designed to have high commercial value.

In Fig. 3 (c), the intermittent blades 3 of adjacent protrusions 7 are alternately shifted so that they are opposite each other. This is to ensure that there is no such thing. Therefore, instead of shifting the intermittent blades 3 of adjacent protrusions 7, the intermittent blades 3 of the protrusions 7 are adjusted as appropriate, such as every other or every second protrusion 7 out of a large number of protrusions 7. The other protrusion 7
The position of the intermittent blades 3 may be shifted in the arrangement direction.

5 in Fig. 3 is the cutting edge 4 of the interrupted blade 3 of each protrusion 7.
This is an escape groove formed at the front in the rotational direction of the groove, into which the cut joint d cut by the intermittent blade 3 is pushed by the rotation of the cutter for cutting fish joints. This relief groove 5 is formed along the arrangement direction (protrusions) of the interrupted blades 3, and if the relief groove 5 is deep, the cutting knots to be cut can enter sufficiently, so the length of the cutting knots becomes long. , the shallower the surface, the shorter the length of the kerifubushi.

(Effects of the Invention) The fish cutting blade of the present invention has the following effects.

Since it does not use a plate-shaped knife, the first
The conventional cutting device shown in Fig. 2, Utility Model 47-
The various drawbacks of the rotary bonito flaking machine No. 41392 have been eliminated.

If the fish d is pressed little by little against the interrupted blade 3, it can be cut as thin as 1/100 mm.

Since the interrupted blade 3 is interrupted by the notch 8,
The cut joint to be cut is not wider than the blade width of the interrupted blade 3. Therefore, by narrowing the blade width of the intermittent blade 3, it is possible to obtain a shavings that can be packed into bags without secondary processing, and there is no need to perform secondary processing such as rolling or pounding to break it into small pieces as in the past. . As a result, work efficiency is greatly improved, less powder is generated, and yields are improved, and the product can be packed into bags as is, which shortens the time it is exposed to air and reduces quality deterioration.

Since the intermittent blades 3 of the protrusions 7 in an appropriate row are shifted in the arrangement direction from the intermittent blades 3 of the protrusions 7 in other rows, the entire cutting surface of the fish joint d is cut without leaving any uncut parts during cutting. Ru.

The intermittent blades 3 are interrupted by notches 8, and the intermittent blades 3 of the protrusions 7 in an appropriate row are shifted in the arrangement direction from the intermittent blades 3 of the protrusions 7 in other rows, so that fish Intermittent blade 3 with multiple protrusions 7 on the cutting surface
rarely occur at the same time. Therefore, the cutting resistance of the interrupted blade 3 is small, and regardless of the force on the interrupted blade 3, wear and damage of the interrupted blade 3 are small. In addition, since the sharpness is less likely to deteriorate, the thickness, shape, etc. of the shavings obtained by cutting become almost constant.

Since the intermittent blades 3 are formed on the protrusions 7, when the intermittent blades 3 are worn out due to use, the protrusions 7 can be repeatedly polished to form the intermittent blades 3, allowing for long-term use.
