Satoshi Okada "Science of Kamaboko" Naruyamado Shoten, July 18, 2000, pages 144-149

The problem to be solved is that the method of kneading the raw material of the kneaded product with a stone mill grinder is a so-called salting process that is carefully and repeatedly applied. Thus, the elution of fish protein could be evaluated in terms of favorable points.
On the other hand, the processing method using a stone mill grinder has a problem that the processing capacity is small as is known.
So, silent cutters and vacuum high-speed cutters were developed to improve the processing capacity, but the processing method of these raw materials is basically added with salt to finely cut fish meat and stirred, The stirring device is complicated, and the stirring function is not always sufficient, and there is a problem that it does not meet the expectation of elution of a desired fish protein.

  Accordingly, the object of the present invention is to improve the processing capability by controlling the kneading of the raw material for the kneaded product while promoting the elution of the fish meat protein and not complicating.

And the gap The supplied kneaded product raw material is caused to pass through the gap by the rotating action of the pair of paddle members, and the kneaded product raw material is compressed during the passage, and the compressed kneaded product raw material is rotated from the gap to the pair of paddle members. To release the compressed state in the casing, to release the compressed state, to stir the expanded raw material for the kneaded product in the casing by the pair of paddle members rotating, and to repeat the above steps This is a kneading method for a raw material for a kneaded product.

The second problem solving means of the present invention is:
A large-diameter first main body having a substantially semi-cylindrical cylindrical body and a circular arc surface on the outer side, and a small-diameter second main body having a circular semi-cylindrical body and a circular arc surface on the outer side. And the first main body part and the second main body part are integrally provided with the respective arc surfaces facing outward, and the first main body part is located at the boundary between the first main body part and the second main body part. A pair of paddle members each having a non-arc surface as a kneading product raw material supply means are provided, and an arc surface outside the first main body of one of the paddle members and a second of the other paddle member. An arc surface of the main body is disposed in the casing with a gap therebetween, and the pair of paddle members are rotated in opposite directions, and the non-arc surface is rotated following the rotation of the pair of paddle members. The raw material for the kneaded product carried into the casing is a gap between the two paddle members. The kneaded product raw material supplied to the gap is allowed to pass through the gap by the rotating action of the pair of paddle members, and the kneaded product raw material is compressed during the passage. The rotational action of the pair of paddle members releases the compressed state in the casing and releases the compressed state, thereby stirring the expanded raw material for the kneaded product in the casing by the pair of rotating paddle members, It is a kneading method of the raw material for kneaded products characterized by repeating each process of.

According to a third aspect of the present invention, there is provided a substantially semi-cylindrical shape having a shaft having a circular cross section, a substantially semi-cylindrical surface on both sides, an outer arc surface, and an inner arc surface formed by approximately half-shaping a cylindrical body. The divided cylindrical body is joined to the shaft by bringing the arc surface inside the divided cylindrical body into contact with a part of the periphery of the shaft, and the substantially semi-finished surface is kneaded and the raw material for the product A pair of paddle members configured as supply means are provided so as to be rotatable in opposite directions, and the outer circular arc surface of the divided cylindrical body of one of the paddle members and the outer peripheral surface of the shaft of the other paddle member Is a kneading apparatus for a kneaded product raw material, wherein the kneading product is disposed in a casing with a gap therebetween.

The fourth problem solving means of the present invention is:
A large-diameter first main body having a substantially semi-cylindrical cylindrical body and a circular arc surface on the outer side, and a small-diameter second main body having a circular semi-cylindrical body and a circular arc surface on the outer side. And the first main body part and the second main body part are integrally provided with the respective arc surfaces facing outward, and the first main body part is located at the boundary between the first main body part and the second main body part. A pair of paddle members formed as kneading product non-arc surfaces as supply means for raw materials for products are provided so as to be rotatable in opposite directions to each other, and an arc surface on the outer side of the first main part of one of the paddle members and the other An apparatus for kneading a raw material for a kneaded product, characterized in that an arc surface of a second main portion of the paddle member is disposed in a casing with a gap therebetween.

Since the first problem-solving means of the present invention is configured as described above, the following effects can be obtained.
In this process, the apparatus itself can be greatly simplified since the raw material for the kneaded product is repeatedly supplied toward the gap between the pair of paddle members that rotate in the opposite direction using the substantially semi-cylindrical surface of the divided cylindrical body.
Moreover, in this problem solving means, since a commercially available material can be used to obtain the shaft and the divided cylindrical body, there is an advantage that it is rich in economy and easy to process.

In addition, since the raw material for the kneaded product is stirred and mixed in the casing by repeating the steps of supply → compression → expansion → stirring, raw materials that have not been experienced before can be processed.
In particular, the process repeatedly compresses the raw material supplied repeatedly, expands the compressed raw material volume so as to restore a pseudo original state, and repeats the stirring process. Since the turbulent flow is generated, sheared, and the raw material for the kneaded product is subjected to pressure from all angles, the promotion of fish protein elution can be expected significantly in combination with the action of salt compared to the background art.

Since the 2nd problem-solving means of this invention is said structure, there exists an effect common to a 1st problem-solving means.
Further, the paddle member can be easily obtained by cutting a steel material.

  The third problem solving means of the present invention has the same effects as the first problem solving means of the present invention.

  The 4th problem-solving means of this invention has an effect common to the 2nd problem-solving means of this invention.

  In addition to being able to sufficiently elute fish protein from the raw material for kneaded products, the purpose of simplifying the means of supplying the raw material for kneaded products has been realized with the minimum number of parts without damaging the physical properties of the raw material for kneaded products .

Example 1 will be described with reference to the drawings, together with the apparatus of the method for kneading the raw material for the kneaded product.
In the examples of the present invention, a raw material for kneaded products (hereinafter referred to as “raw material W”) was prepared by mixing fish meat surimi (specifically frozen surimi) with salt and water.
In Example 1, in order to see the superiority of the gel strength, for the sake of convenience, a fish paste with salt and water added is used, but this is not a limitation.
The raw material for the kneaded product targeted by the original kneading method of the present invention is based on a fish paste prepared by adding salt, water, sugar, starch or the like.
Although the present invention has the theme of performing the functions of “salt shear” and “main shear” at the same time, as described below, the present invention can be diverted to so-called “empty shear” and “main shear”. Is.
Here, “Kazuri” means that the fish meat is agitated and minced before adding salt, and “Suzuri” is added to the fish meat and salted, then added to the secondary ingredients and stirred and mixed. To do.

  The basic configuration of the present invention is to rotate a pair of paddle members A described below in opposite directions, but the configuration of the pair of paddle members A is exactly the same. The description of the configuration of the other paddle member A is omitted, and the description of the one paddle member A is incorporated.

Therefore, one paddle member A will be described (see FIG. 1). The paddle member A is configured by combining a shaft 10 having a circular cross section and a substantially semi-cylindrical divided cylindrical body 12.
The shaft 10 rotates the paddle member A and constitutes a part of the paddle member A itself.
In the illustrated example, the shaft 10 has a circular cross section by a hollow sleeve, and a drive shaft 16 connected to a drive source (not shown) is mounted inside.

  The shaft 10 may be a non-hollow shaft instead of the hollow sleeve described above, and the illustration thereof is omitted. However, drive shafts connected to a drive source are also provided on both sides in the longitudinal direction of the shaft 10.

  As another component constituting the paddle member A, a substantially semi-cylindrical shape having substantially semi-cylindrical surfaces 12a on both sides formed by semi-coiling a cylindrical body, and further comprising an outer arc surface 12b and an inner arc surface 12c. The divided cylindrical body 12 is provided.

The arcuate surface 12 c inside the divided cylindrical body 12 is in contact with a part of the periphery of the shaft 10, and the divided cylindrical body 12 is coupled to the shaft 10.
In this case, the invention has been devised as one of the features of the present invention, and the above-mentioned substantially semi-finished surfaces 12a are configured as the raw material W supply means for the purpose of supplying the raw material W in the casing 14.
Then, in order to perform sufficient mixing and stirring without causing the raw material W to stay in the casing 14 and to allow the raw material W to be forcibly pushed out by providing a gap α, which will be described later, The angle between the circular arc surfaces 12c is set to approximately 75 degrees.
It should be noted that the angle between the substantially semi-cylindrical surface 12a and the inner arcuate surface 12c is not limited to this angle, and is preferably provided between approximately 70 degrees and approximately 90 degrees.

The substantially semi-finished surfaces 12a on both sides constituting the supply means for repeatedly supplying the raw material W can be easily processed by substantially half-shaping the cylindrical body, so the supply means for the raw material W is greatly simplified. It is also economically rich.
The raw material W here is a mixture of salt and water in the fish meat after the “blank” (not mixed with salt) described above.

  The divided cylindrical body 12 constituting the paddle member A rotates, and the substantially semi-finished surface 12a governed by the rotation inevitably also rotates, so that the substantially semi-assembled surface 12a causes the raw material W in the casing 14 to pass through the next step. This has the effect of forcibly pushing out toward the surface.

  A pair of the paddle members A described above is provided, and an arcuate surface 12b on the outer side of the divided cylindrical body 12 of one paddle member A and an outer peripheral surface 10a of the shaft 10 of the other paddle member A are separated from each other by a gap α. The paddle member A is disposed in the casing 14 and is housed in the casing 14 as a pair. The arcuate surface 12b of the split cylindrical body 12 of one paddle member A faces the inner peripheral surface 14a of the casing 14. The outer circular arc surface 12b of the divided cylindrical body 12 of the other paddle member A always rotates so as to face the outer peripheral surface 10a of the shaft 10 of the one paddle member A, so that the kneaded product of the present invention is used. The basics of the raw material kneading apparatus 20 are configured.

As a specific example of the gap α, the inventors experimentally set the gap α to about 1 mm. However, the present invention is not limited to about 1 mm from the beginning, and may be changed as long as the raw material W can be compressed.
By setting the gap α to about 1 mm, the raw material W is forced to be extruded through the substantially semi-finished surface 12a. As a result, the raw material W is compressed by the gap α in order to promote protein elution in the fish paste. However, it can also be sheared.

Regarding the flow speed of the raw material W when it passes through the gap α, the central portion of the gap α is the fastest at the maximum, the outer arcuate surface 12b side is the next fastest, and the outer peripheral surface 10a side of the shaft 10 is slow.
The difference in speed is considered that the stress difference due to the difference in diameter between the outer arcuate surface 12b and the outer peripheral surface 10a of the shaft 10 affects the raw material W. As a result, the shearing is considered to occur when the gap α passes.

  And unlike the background art, where shearing is simply cut finely with a blade, it is considered that the raw material W is compressed and changed into a thin sheet-like material, so that it has not been experienced in the past. It can be said that the effect by this was expected.

The cross-sectional form of the inner peripheral surface 14 a of the casing 14 is made to correspond to the outer arc surface 12 b of the split cylindrical body 12 of the pair of paddle members A, and the outer arc surface 12 b and the inner peripheral surface of the casing 14. 14a is provided with a constant gap β (see FIG. 1).
The above-described gap β is experimentally set to about 1 mm as a specific example, similar to the gap α between the outer arcuate surface 12b and the outer peripheral surface 10a of the shaft 10.
Since the cross-sectional form of the inner peripheral surface 14a of the casing 14 corresponds to the arcuate surface 12b outside the divided cylindrical body 12, the raw material W that is repeatedly moved in the casing 14 is smoothly moved without receiving a load. The
Therefore, this enables sufficient stirring and mixing of the raw material W in the casing 14.

  Further, although not shown in the drawings, the raw material W processed in the casing 14 is continuously provided outside the casing 14 by providing the raw material carry-in port connected to the carry-in pump on one side of the casing 14 and the raw material carry-out port on the other side. It is also planned to be able to carry it out.

  Then, the invention of the method of the embodiment of the present invention will be further described together with the operation of the kneaded product raw material kneading apparatus 20 described above. First, the pair of paddle members A are rotated in opposite directions.

Next, by means of the substantially semi-cylindrical surface 12a that rotates following the rotation of the pair of paddle members A, the raw material W in the casing 14 is moved by the paddle member A on the left side of FIG. Supply is made by forcibly pushing into the gap α between the members A.
The raw material W is pushed out by the left paddle member A as shown by an arrow X.

The raw material W supplied to the gap α is passed through the gap α by the rotating action of the pair of paddle members A, and the raw material W is compressed during the passage.
When the gap α is set to about 1 mm as described above at the time of this step, in particular, the raw material W is forcibly extruded through the substantially semi-finished surface 12a, and the raw material W can be sheared while being compressed by the gap α. Further promotion of protein elution can be expected.

  The compressed raw material W is released from the gap α into the casing 14 by the rotational action of the pair of paddle members A to release the compressed state, and the compressed state is released, thereby rotating the expanded raw material W. A turbulent flow is generated in the casing 14 by the paddle member A and stirred, and the above steps are repeated (see FIG. 2).

Furthermore, the cross-sectional form of the inner peripheral surface 14a of the casing 14 is made to correspond to the arcuate surface 12b on the outer side of the divided cylindrical body 12 of the pair of paddle members A, and the raw material W is returned to the original position again without any load. The process is repeated to further promote protein elution.
That is, this effect is that the raw material W supplied into the casing 14 is pushed out by the substantially semi-ridged surface 12a facing the rotation direction of the divided cylindrical body 12 constituting one paddle member A when the shaft 10 rotates, and the paddle member The paddle member A is compressed by passing through a gap α formed by the outer circumferential surface 10a of the shaft 10 of A and the arcuate surface 12b of the outer side of the divided cylindrical body 12 of the other paddle member A, and immediately back in the rotational direction. This is because sufficient agitation can be achieved by repeatedly performing a series of operations that are opened to the space formed in the substantially semi-cylindrical surface 12a of the divided cylindrical body 12 and the casing 14.

Thus, since the raw material W repeats the steps of supply → compression → expansion → stirring in the casing, the raw material W that has not been experienced in the past can be processed.
In particular, since the raw material W is compressed, stirred, and sheared, the process of expanding the compressed raw material W so as to restore the volume of the raw material W to a pseudo original state is repeated. Can be expected significantly.

The configuration of the paddle member A described in the first embodiment described above is based on the combination of the substantially semi-cylindrical divided cylindrical body 12 and the shaft 10, but in this embodiment, the first main body 12B and the second main body 12B The main body portion 10B is an integral body and a material such as steel is cut.
And there is no change about the kneading | mixing method of the raw material for kneaded products by adoption of a pair of paddle member A, and its apparatus.
Therefore, it can be said that there is only a difference in production technology and there is no difference in function as the paddle member A.

In this embodiment, the cylindrical body is formed in a substantially semi-cylindrical shape, the large-diameter first main body portion 12B having a circular arc surface 12d and the cylindrical body are formed in a substantially semi-cylindrical shape, and the circular arc surface 10b is provided on the outer side. A small-diameter second main body portion 10B is provided.
The first main body portion 12B and the second main body portion 10B are integrally provided with the respective arcuate surfaces 12d and 10b facing outward.
At the boundary between the first main body portion 12B and the second main body portion 10B, there is provided a pair of paddle members A formed by configuring the non-arc surface 12e of the first main body portion 12B as a kneading product raw material supply means. .
In addition, the non-circular arc surface 12e and the circular arc surface are provided so that the raw material W can be sufficiently mixed and stirred without being retained in the casing 14, and the raw material W can be forcibly pushed out by providing a gap α to be described later. The angle between 10b is set to approximately 105 degrees.
The angle between the non-arc surface 12e and the arc surface 10b is not limited to this angle, and is preferably provided between approximately 90 degrees and approximately 110 degrees.

  By cutting a cylindrical steel material, non-arc surfaces 12e are provided on both sides of the material in the longitudinal direction of the steel material, and the diameter of the second main body portion 10B is compared with the diameter of the first main body portion 12B. There is no particular difficulty in processing small.

  An arc surface 12d outside the first main body portion 12B of one paddle member A and an arc surface 10b of the second main body portion 10B of the other paddle member A are disposed in the casing 14 with a gap α therebetween. As a result, this kneaded product raw material kneading apparatus 20 is obtained.

  Therefore, a method for kneading a raw material for a kneaded product will be described based on the apparatus 20. Although not fundamentally different from the first embodiment, the pair of paddle members A are rotated in opposite directions.

  The raw material W carried into the casing 14 is supplied to the gap α between the two paddle members A by the non-circular surface 12e that rotates following the rotation of the pair of paddle members A.

  The raw material W supplied to the gap α is passed through the gap α by the rotating action of the pair of paddle members A, and the raw material W is compressed during the passage.

  The compressed raw material W is released from the gap α into the casing 14 by the rotating action of the pair of paddle members A to release the compressed state.

  By releasing the compressed state, the expanded raw material W is stirred in the casing 14 by the pair of paddle members A that rotate, and the above-described steps are repeated.
