Description

The present invention relates to a noodle-making cutting device for cutting a noodle band into noodle strands using a cutting blade roll in the production of noodles, and a method for producing noodles using the noodle-making cutting device.

Conventionally, the mainstream method for cutting out noodle strings mechanically involves passing a thin strip of noodle dough, which has been rolled out, between a pair of opposing rotating cutting blade rolls, and cutting out the noodle strings into linear shapes. Each of these pair of cutting blade rolls has multiple annular protrusions formed in the circumferential direction, and multiple annular recesses (grooves) formed between the protrusions.

For example, a square-blade type cutting blade roll cuts the noodle strip by fitting a convex pressing portion (also called a mountain) formed on one cutting blade roll into a concave fitting portion (also called a groove) on the other cutting blade roll. The cut noodle strips are pressed into the fitting portions of the multiple spaces created by the meshing of the opposing cutting blade rolls, that is, into the spaces formed by the pressing portion and the fitting portion.

The noodle strings that are pushed into the insertion portion (groove) are in close contact with the side of the groove, and so rotate and move as the cutting blade roll rotates. The noodle strings that are in close contact with the side of the groove are scraped out of the groove by a scraper (scraping portion, scraper) that has comb-shaped teeth. Specifically, the tips of the teeth (scraping teeth) formed on the scraper are inserted into the groove, and the noodle strings that rotate and move as the cutting blade roll rotates are scraped out of the groove.

Usually, the noodle strands are the same thickness, but there are also so-called "randomly cut noodles" that contain noodle strands of different thicknesses. "Randomly cut noodles" contain noodle strands of different thicknesses, which allows you to feel the difference in texture. "Randomly cut noodles" have a texture similar to that of hand-cut noodles.

As a device for cutting out noodle strings of different thicknesses, a device has been disclosed that cuts out noodle strings of different thicknesses for each section (for each certain number of noodle strings) in the longitudinal direction of a cutting blade roller (cutting blade roll) (see, for example, Patent Documents 1 and 2).
Also disclosed is a device that cuts out noodle strings of different thicknesses for each section (for each certain number of noodle strings) in the longitudinal direction of the cutting blade roller (cutting blade roll), as well as a device that makes the spacing between the cutting blades and/or the depth of the recesses formed between the cutting blades uneven (see, for example, Patent Document 3).

Here, for fresh noodles, the noodle strands cut out in this way are cut to a fixed length and dusted with flour to prevent the noodle strands from sticking together, but for mass-produced chilled noodles, frozen noodles, or instant noodles, the noodle strands cut out in this way must be transported on a conveyor and continuously steamed or boiled to gelatinize the noodle strands.

However, when gelatinizing noodle strings by steaming or boiling, it takes a certain amount of time, so the speed of the conveyor passing through the steam chamber for steaming or the boiling tank for boiling must be significantly slower than the cutting speed when cutting out the noodle strings. Meanwhile, adjacent noodle strings or overlapping noodle strings that have been cut out may stick together during the gelatinization process or when transported. This is particularly noticeable when gelatinizing noodle strings by steaming.

When noodle strands stick together, they do not come apart during cooking or eating, and can form clumps, or if you try to forcefully separate them, the noodle strands can break into short pieces. There can also be the inconvenience of the stuck-together parts not being fully gelatinized. Furthermore, in the case of instant noodles, cut noodles are usually steamed and then dried, but if they are fried or dried with hot air while still stuck together, the stuck parts will not dry sufficiently and will remain raw, resulting in a defective product.

In order to prevent this sticking, particularly in the case of steamed noodles, the noodle strands cut by a pair of opposing cutting blade rolls are passed through a conduit or the like immediately after cutting to give them waves (usually fine, strong waves are given in the vertical direction) so that the noodle strands do not stick together in a linear or flat shape as much as possible. In other words, the contact area between the noodle strands is reduced to prevent them from sticking together.

However, when wavy noodle strings are steamed in this way, the noodle strings are gelatinized while still in a wavy state on the conveyor, so the noodle strings become fixed with a strong wavy shape. Therefore, even if a process of stretching (pulling) the noodle strings is added after steaming, the noodles will become curly with a wavy shape remaining. Here, raw noodles are generally straight, except in special cases. Curly noodles are strange and undesirable, especially in soba, udon, spaghetti, etc.

There is a high demand for non-wavy noodles, but as mentioned above, if the noodles are not wavy, there is an issue that adjacent or overlapping noodle strands stick together.

In addition, each of the multiple first insertion portions 216 and the multiple second insertion portions 226 is a portion into which the sheared noodle band 2 (raw noodle strings 3) is pressed and inserted by a multiple second pushing portions 232 formed on the second cutting blade roll 230.

Each of the multiple first pressing portions 212 is a convex portion formed in an annular shape along the circumferential direction on the outer surface of the first cutting blade roll 210. Each of the multiple first pressing portions 212 is formed at predetermined intervals in the direction of the first rotation axis C1.
The first pressing portions 212 include a first narrow pressing portion 213A and a first wide pressing portion 213B having a width, which is a length in the first rotation axis C1 direction, wider than the first narrow pressing portion 213A. The widths, included ratios, and arrangements of the first narrow pressing portion 213A and the first wide pressing portion 213B are formed to correspond to the widths, included ratios, and arrangements of a third insertion portion 236 and a fourth insertion portion 246 of the second cutting blade roll 230 described later.
The first fitting portions 216 or the second fitting portions 226 are disposed between the multiple first pushing portions 212 .

Each of the first and second insertion portions 216 and 226 is a concave portion formed in a ring shape along the circumferential direction on the outer surface of the first cutting blade roll 210. Each of the first and second insertion portions 216 and 226 is formed between each of the first push-in portions 212.

The first fitting portions 216 and the second fitting portions 226 are arranged alternately in the direction of the first rotation axis C1.
Each of the multiple first fitting portions 216 is a fitting portion into which the fitted raw noodle strings 3 are scraped out by the first scraping portion 251 of the first scraping body 250 at the first scraping-out position T1.
Each of the multiple second fitting portions 226 is a fitting portion into which the fitted raw noodle strings 3 are scraped out at the second scraping position T2 by the second scraping portion 256 of the first scraping body 250.

In detail, each of the first insertion portions 216 is a concave portion into which each of the first scraping teeth 252 in the first scraping portion 251 of the first scraping body 250 is inserted. Each of the first insertion portions 216 is an insertion portion into which the inserted raw noodle strings 3 are scraped out at the first scraping position T1 by each of the first scraping teeth 252 in the first scraping portion 251 of the first scraping body 250.

Each of the second insertion portions 226 is a concave portion into which each of the second scraping teeth 257 in the second scraping portion 256 of the first scraper body 250 is inserted. Each of the second insertion portions 226 is an insertion portion into which the inserted raw noodle strings 3 are scraped out at the second scraping position T2 by each of the second scraping teeth 257 in the second scraper portion 256 of the first scraper body 250.

As shown in Figures 2 and 5, the multiple first insertion portions 216 include multiple first narrow portions 217 and multiple first wide portions 218 that have a width (length in the direction of the first rotation axis C1) wider than the first narrow portions 217.
The width of each of the plurality of first narrow portions 217 is generally set to 1 to 5 mm, for example, 1.15 to 3.3 mm, but is not limited to this.
The width of each of the plurality of first wide portions 218 is generally set to 1 to 5 mm, and is set to be wider than the width of the first narrow portion 217 .
The numerical values and ratio of the width of the first narrow portion 217 and the width of the first wide portion 218 can be adjusted as appropriate based on factors such as the desired texture and suppression of overlapping of the raw noodle strings 3.

In addition, in the first fitting group 216A, which is a group of multiple first fitting portions 216, the first narrow portions 217 and the first wide portions 218 are mixed and arranged in a ratio of 2:1, but this is not limited to this. For example, in the first fitting group 216A, which is a group of multiple first fitting portions 216, the first narrow portions 217 and the first wide portions 218 are preferably mixed and arranged in a ratio of 1:4 to 4:1. In addition, in the first fitting group 216A, at least one of the first narrow portions 217 and the first wide portions 218 is arranged so as not to be continuous in the first rotation axis direction C1.

As shown in Figures 2 and 5, the multiple second insertion portions 226 include multiple second narrow portions 227 and multiple second wide portions 228 that have a width (length in the direction of the first rotation axis C1) wider than the second narrow portions 227.
The width of each of the plurality of second narrow portions 227 is generally set to 1 to 5 mm, for example, 1.15 to 3.3 mm, but is not limited to this.
The width of each of the plurality of second wide portions 228 is generally set to 1 to 5 mm, and is set to be wider than the width of the second narrow portion 227 .
The numerical values and ratio of the width of the second narrow portion 227 and the width of the second wide portion 228 can be adjusted as appropriate based on factors such as the desired texture and suppression of overlapping of the raw noodle strings 3.

In addition, in the second fitting group 226A, which is a group of multiple second fitting portions 226, the second narrow portions 227 and the second wide portions 228 are mixed and arranged in a ratio of 2:1, but this is not limited to this. For example, in the second fitting group 226A, which is a group of multiple second fitting portions 226, the second narrow portions 227 and the second wide portions 228 are preferably mixed and arranged in a ratio of 1:4 to 4:1. In the second fitting group 226A, at least one of the second narrow portions 227 and the second wide portions 228 is arranged so as not to be continuous in the first rotation axis direction C1.

In the first insertion group 216A, the first narrow portion 217 and the first wide portion 218 are preferably arranged so that a predetermined arrangement pattern is repeated in multiple sets in the direction of the first rotation axis C1. For example, in this embodiment, the first narrow portion 217 and the first wide portion 218 are arranged so that a predetermined arrangement pattern of the first narrow portion 217, the first narrow portion 217, and the first wide portion 218 is repeated in multiple sets in the direction of the first rotation axis C1.

Furthermore, in the second insertion group 226A, the second narrow portion 227 and the second wide portion 228 are preferably arranged so that a predetermined arrangement pattern is repeated in multiple sets in succession in the direction of the first rotation axis C1. For example, in this embodiment, the second narrow portion 227 and the second wide portion 228 are arranged so that the arrangement pattern of the second narrow portion 227, the second narrow portion 227, and the second wide portion 228 is repeated in multiple sets in succession in the direction of the first rotation axis C1.

By arranging the multiple first insertion portions 216 (first narrow portion 217, first wide portion 218) and multiple second insertion portions 226 (second narrow portion 227, second wide portion 228) as described above, for example, when the raw noodle strings 3 are separated into multiple lanes divided in the direction of the first rotation axis C1, the types (different thicknesses) of raw noodle strings contained in the group of raw noodle strings separated in each lane are uniform, which is preferable because it contributes to uniform product quality.

In addition, the first depth, which is the length of the first fitting portion 216 in the first diameter direction perpendicular to the first rotation axis C1, is different from the second depth, which is the length of the second fitting portion 226 in the first diameter direction. Specifically, the first depth of the first fitting portion 216 is shallower than the second depth of the second fitting portion 226. In other words, the second depth of the second fitting portion 226 is deeper than the first depth of the first fitting portion 216.

In this embodiment, the raw noodle strings 3 inserted into the first insertion portion 216 are scraped out at the first scraping position T1. The raw noodle strings 3 scraped out at the first scraping position T1 collide with the first scraping portion 251 (first scraping tooth 252) in such a way that a force is applied mainly in the vertically downward direction, and are scraped out so as to flow vertically downward. In contrast, the raw noodle strings 3 inserted into the second insertion portion 226 are scraped out at the second scraping position T2, which is downstream in the first rotation direction R1 from the first scraping position T1. The raw noodle strings 3 scraped out at the second scraping position T2 collide with the second scraping portion 256 (second scraping tooth 258) in such a way that a force is applied vertically downward and horizontally, and are scraped out so as to flow vertically downward.

To deal with this, it is preferable that the second scraping portion 256 (second scraping tooth 258) is inserted deeper into the insertion portion so that it can withstand the (horizontal) force applied by the raw noodle strings 3 and can scrape out the raw noodle strings 3 reliably even if it is deformed by the force from the raw noodle strings 3. Therefore, in this embodiment, the second insertion portion 226 is formed so that the second depth of the second insertion portion 226 is deeper than the first depth of the first insertion portion 216.

In this embodiment, the second depth of the second insertion portion 226 is configured to be deeper than the first depth of the first insertion portion 216, but this is not limited thereto, and the second depth of the second insertion portion 226 and the first depth of the first insertion portion 216 may be configured to be the same depth by adjusting the material, shape, and structure of the first scraping portion 251 (first scraping tooth 252) and the second scraping portion 256 (second scraping tooth 258).

As described above, the first insertion portion 216 and the second insertion portion 226 are arranged alternately in the direction of the first rotation axis C1. Therefore, the insertion portion of the first depth (shallow insertion portion) and the insertion portion of the second depth (deep insertion portion) are arranged alternately in the direction of the first rotation axis C1.

As shown in Figures 1 and 2, the second cutting blade roll 230 has a plurality of convex second pushing portions 232 formed in a ring shape along the circumferential direction, and a plurality of concave third insertion portions 236 and a plurality of concave fourth insertion portions 246 formed in a ring shape along the circumferential direction and respectively formed between the plurality of second pushing portions 232.

In addition, each of the multiple third insertion portions 236 and the multiple fourth insertion portions 246 is a portion into which the sheared noodle band 2 (raw noodle strings 3) is pressed and inserted by the multiple first pushing portions 212 formed on the first cutting blade roll 210.

Each of the second pressing portions 232 is a convex portion formed in an annular shape along the circumferential direction on the outer surface of the second cutting blade roll 230. Each of the second pressing portions 232 is formed at predetermined intervals in the direction of the second rotation axis C2.
The second pressing portions 232 include a second narrow pressing portion 233A and a second wide pressing portion 233B having a width greater than that of the second narrow pressing portion 233A in the second rotation axis C2 direction. The widths, proportions, and arrangements of the second narrow pressing portion 233A and the second wide pressing portion 233B correspond to the widths, proportions, and arrangements of the first insertion portion 216 and the second insertion portion 226 of the first cutting blade roll 210.
The third fitting portion 236 or the fourth fitting portion 246 is disposed between the multiple second pushing portions 232 .

Each of the third insertion portions 236 and the fourth insertion portions 246 is a concave portion formed in a ring shape along the circumferential direction on the outer surface of the second cutting blade roll 230. Each of the third insertion portions 236 and the fourth insertion portions 246 is formed between the second push-in portions 232.

Each of the multiple fourth insertion portions 246 is an insertion portion into which the inserted raw noodle strings 3 are scraped out at the fourth scraping position T4 by the fourth scraping portion 266 of the second scraping body 260.

In detail, each of the multiple third insertion portions 236 is a concave portion into which each of the multiple third scraping teeth in the third scraping portion 261 of the second scraping body 260 is inserted. Each of the multiple third insertion portions is an insertion portion into which the inserted raw noodle strings 3 are scraped out at the third scraping position T3 by each of the multiple third scraping teeth in the third scraping portion 261 of the second scraping body 260.

Each of the multiple fourth insertion portions 246 is a concave portion into which each of the multiple fourth scraping teeth in the fourth scraping portion 266 of the second scraping body 260 is inserted. Each of the multiple fourth insertion portions is an insertion portion into which the inserted raw noodle strings 3 are scraped out at the fourth scraping position T4 by each of the multiple fourth scraping teeth in the fourth scraping portion 266 of the second scraping body 260.

As shown in Figures 2 and 5, the multiple third insertion portions 236 include multiple third narrow portions 237 and multiple third wide portions 238 that have a width (length in the direction of the second rotation axis C2) that is wider than the third narrow portions 237.
The width of each of the third narrow portions 237 is generally set to 1 to 5 mm, for example, 1.15 to 3.3 mm, but is not limited to this range.
The width of each of the plurality of third wide portions 238 is generally set to 1 to 5 mm, and is set to be wider than the width of the third narrow portion 237 .
The numerical values and ratio of the width of the third narrow portion 237 and the width of the third wide portion 238 can be adjusted as appropriate based on factors such as the desired texture and suppression of overlapping of the raw noodle strings 3.

In addition, in the third fitting group 236A, which is a group of the multiple third fitting portions 236, the third narrow portion 237 and the third wide portion 238 are mixed and arranged in a ratio of 2:1, but this is not limited to this. For example, in the third fitting group 236A, which is a group of the multiple third fitting portions 236, the third narrow portion 237 and the third wide portion 238 are preferably mixed and arranged in a ratio of 1:4 to 4:1. In addition, in the third fitting group 236A, at least one of the third narrow portion 237 and the third wide portion 238 is arranged so as not to be continuous in the second rotation axis direction C2.

As shown in Figures 2 and 5, the multiple fourth insertion portions 246 include multiple fourth narrow portions 247 and multiple fourth wide portions 248 that have a width (length in the direction of the second rotation axis C2) that is wider than the fourth narrow portions 247.
The width of each of the plurality of fourth narrow portions 247 is generally set to 1 to 5 mm, for example, 1.15 to 3.3 mm, but is not limited to this.
The width of each of the plurality of fourth wide portions 248 is generally set to 1 to 5 mm, and is set to be wider than the width of the fourth narrow portion 247 .
The numerical values and ratio of the width of the fourth narrow portion 247 and the width of the fourth wide portion 248 can be adjusted as appropriate based on factors such as the desired texture and the prevention of overlapping of the raw noodle strings 3.

In addition, in the fourth fitting group 246A, which is a group of the multiple fourth fitting portions 246, the fourth narrow portion 247 and the fourth wide portion 248 are mixed and arranged in a ratio of 2:1, but this is not limited to this. For example, in the fourth fitting group 246A, which is a group of the multiple fourth fitting portions 246, the fourth narrow portion 247 and the fourth wide portion 248 are preferably mixed and arranged in a ratio of 1:4 to 4:1. In addition, in the fourth fitting group 246A, at least one of the fourth narrow portion 247 and the fourth wide portion 248 is arranged so as not to be continuous in the second rotation axis direction C2.

In the third insertion group 236A, the third narrow portion 237 and the third wide portion 238 are preferably arranged so that a predetermined arrangement pattern is repeated in multiple sets in the direction of the third rotation axis C3. For example, in this embodiment, the third narrow portion 237 and the third wide portion 238 are arranged so that the arrangement pattern of the third narrow portion 237, the third narrow portion 237, and the third wide portion 238 is repeated in multiple sets in the direction of the second rotation axis C2.

Furthermore, in the fourth insertion group 246A, the fourth narrow portion 247 and the fourth wide portion 248 are preferably arranged so that a predetermined arrangement pattern is repeated in multiple sets in the direction of the second rotation axis C2. For example, in this embodiment, the fourth narrow portion 247 and the fourth wide portion 248 are arranged so that a predetermined arrangement pattern of the fourth narrow portion 247, the fourth narrow portion 247, and the fourth wide portion 248 is repeated in multiple sets in the direction of the second rotation axis C2.

By arranging the multiple third insertion portions 236 (third narrow portion 237, third wide portion 238) and multiple fourth insertion portions 246 (fourth narrow portion 247, fourth wide portion 248) as described above, for example, when the raw noodle strings 3 are separated into multiple lanes divided in the direction of the second rotation axis C2, the types (different thicknesses) of raw noodle strings contained in the group of raw noodle strings separated in each lane are uniform, which is preferable because it contributes to uniform product quality.

In addition, the third depth, which is the length of the third fitting portion 236 in the second diameter direction perpendicular to the second rotation axis C2, is different from the third depth, which is the length of the fourth fitting portion 246 in the second diameter direction. Specifically, the third depth of the third fitting portion 236 is shallower than the fourth depth of the fourth fitting portion 246. In other words, the fourth depth of the fourth fitting portion 246 is deeper than the third depth of the third fitting portion 236.

In this embodiment, the raw noodle strings 3 inserted into the third insertion portion 236 are scraped out at the third scraping position T3. The raw noodle strings 3 scraped out at the third scraping position T3 collide with the third scraper 261 (third scraping tooth) in such a way that a force is applied mainly in the vertically downward direction, and are scraped out so as to flow vertically downward. In contrast, the raw noodle strings 3 inserted into the fourth insertion portion 246 are scraped out at the fourth scraping position T4, which is downstream of the third scraping position T3 in the second rotation direction R2. The raw noodle strings 3 scraped out at the fourth scraping position T4 collide with the fourth scraper 266 (fourth scraping tooth) in such a way that a force is applied vertically downward and horizontally, and are scraped out so as to flow vertically downward.

To deal with this, it is preferable that the fourth scraping portion 266 (fourth scraping tooth) is inserted deeper into the insertion portion so that it can withstand the (horizontal) force applied by the raw noodle strings 3 and can scrape out the raw noodle strings 3 reliably even if it is deformed by the force from the raw noodle strings 3. Therefore, in this embodiment, the fourth insertion portion 246 is formed so that the fourth depth of the fourth insertion portion 246 is deeper than the third depth of the third insertion portion 236.

In this embodiment, the fourth depth of the fourth insertion portion 246 is configured to be deeper than the third depth of the third insertion portion 236, but this is not limited thereto, and the fourth depth of the fourth insertion portion 246 and the fourth depth of the third insertion portion 236 may be configured to be the same depth by adjusting the material, shape, and structure of the third scraping portion 261 (third scraping tooth) and the fourth scraping portion 266 (fourth scraping tooth).

As described above, the third insertion portion 236 and the fourth insertion portion 246 are arranged alternately in the direction of the second rotation axis C2. Therefore, the insertion portion of the third depth (shallow insertion portion) and the insertion portion of the fourth depth (deep insertion portion) are arranged alternately in the direction of the second rotation axis C2.

1, the first scraper body 250 is attached to the first roll of cutting blades 210. The first scraper body 250 is attached to the housing below the first roll of cutting blades 210 by an attachment member 291 inserted into an attachment hole 281.
The second scraper body 260 is attached to the second roll of cutting blades 230. The second scraper body 260 is attached to the housing below the second roll of cutting blades 230 by an attachment member 292 inserted into the attachment hole 282.

Each scraper is attached so that the angle that the tips of the scraping teeth make with the tangent line, which is the contact angle with each cutting blade roll, is in the range of, for example, 10° to 60°. It is preferable to adjust the installation position of each scraper so that the contact angle is set in the above-mentioned range, and so that the installation position is such that the raw noodle strings are easily scraped out and the tips of the teeth of the scraper are worn down as little as possible.
Below, we will mainly explain the arrangement and shape of the first scraper body 250 that is attached to the first cutting blade roll 210, but the arrangement and shape of the second scraper body 260 that is attached to the second cutting blade roll 230 are also similar, and the explanation of the first scraper body 250 can be used.

As shown in Figs. 1 and 3, the first scraper body 250 has a first scraper portion 251, a second scraper portion 256, and the above-mentioned mounting hole 281. The first scraper body 250 is a scraper body in which the first scraper portion 251 and the second scraper portion 256 are integrally formed, and scrapes out the raw noodle strings 3 at two scraping positions. The first scraper body 250 is an integrated scraper body having the first scraper portion 251 that scrapes out the raw noodle strings 3 at the first scraping position T1, and the second scraper portion 256 that scrapes out the raw noodle strings 3 at the second scraping position T2.

The first scraping portion 251 is a portion that scrapes out the raw noodle strings 3 at the first scraping position T1 on the upstream side close to the meshing position K. The first scraping portion 251 has a plurality of first scraping teeth 252 that are inserted into a plurality of first insertion portions 216 at the first scraping position T1 on the first cutting blade roll 210.

The multiple first scraping teeth 252 are longer than the second scraping teeth 257 described below. The multiple first scraping teeth 252 extend toward the meshing position K (diagonally upward), and are formed so that their tips are bent toward the first cutting blade roll 210 (upward). The multiple first scraping teeth 252 are adjusted to have a shape suitable for scraping out the raw noodle strings 3 and flowing them vertically.

The multiple first scraping teeth 252 include multiple first narrow scraping teeth 253 and multiple first wide scraping teeth 254 .
The first narrow scraping tooth 253 is a scraping tooth that is inserted into the first narrow portion 217 of the first cutting blade roll 210 .
The first wide scraping tooth 254 is a scraping tooth that is inserted into the first wide portion 218 of the first cutting blade roll 210 .
The widths, arrangement patterns, etc. of the first narrow scraping teeth 253 and the first wide scraping teeth 254 are set corresponding to the first narrow portion 217 and the first wide portion 218 .

The second scraping portion 256 is a portion that scrapes out the raw noodle strings 3 at a second scraping position T2 that is downstream of the first meshing position T1 in the first rotation direction R1. The second scraping portion 256 has a plurality of second scraping teeth 257 that are inserted into a plurality of second insertion portions 226 at a second scraping position T2 that is different from the first scraping position T1 on the first cutting blade roll 210.

The second scraping teeth 257 are shorter than the first scraping teeth 252 described above. The second scraping teeth 257 are formed so that their bases are bent toward the first cutting blade roll 210 (upward). The second scraping teeth 257 are adjusted to have a shape suitable for scraping out the raw noodle strings 3 and flowing them vertically.

The multiple second scraping teeth 257 include multiple second narrow scraping teeth 258 and multiple second wide scraping teeth 259 .
The second narrow scraping tooth 258 is a scraping tooth that is inserted into the second narrow portion 227 of the first cutting blade roll 210.
The second wide scraping tooth 259 is a scraping tooth that is inserted into the second wide portion 228 of the first cutting blade roll 210.
The widths, arrangement patterns, etc. of the second narrow scraping teeth 258 and the second wide scraping teeth 259 are set corresponding to the second narrow portion 227 and the second wide portion 228 .

As shown in Figs. 1 and 3, the second scraper body 260 has a third scraper portion, a fourth scraper portion 266, and an attachment hole. The second scraper body 260, like the first scraper body 250, is a scraper body in which the third scraper portion 261 and the fourth scraper portion 266 are integrally formed, and scrapes out the raw noodle strings 3 at two scraping positions. The second scraper body 260 is an integrated scraper body having the third scraper portion 261 that scrapes out the raw noodle strings 3 at the third scraping position T3, and the fourth scraper portion 266 that scrapes out the raw noodle strings 3 at the fourth scraping position T4.

The third scraping portion 261 is a portion that scrapes out the raw noodle strings 3 at a third scraping position T3 on the upstream side close to the meshing position K. The third scraping portion 261 has a plurality of third scraping teeth that are inserted into a plurality of third insertion portions 236 at the third scraping position T3 on the second cutting blade roll 230.

The fourth scraping portion 266 is a portion that scrapes out the raw noodle strings 3 at a fourth scraping position T4 that is downstream of the third meshing position T3 in the second rotation direction R2. The fourth scraping portion 266 has a plurality of fourth scraping teeth that are inserted into a plurality of fourth insertion portions 246 at the fourth scraping position T4, which is different from the third scraping position T3 on the second cutting blade roll 230.

Here, the shapes and structures of the third scraping tooth and the fourth scraping tooth refer to the explanation of the first scraping tooth 252 and the second scraping tooth 257 described above.

The noodle-making cutting device 200 in this embodiment can cut out multiple types of noodle strings with different thicknesses and prevent the multiple types of noodle strings from sticking together. The noodle-making cutting device 200 in this embodiment is configured to scrape out multiple types of noodle strings with different thicknesses at two different scraping positions on each cutting blade roll and scrape out noodle strings from every other insertion portion at each scraping position, so it can prevent the multiple types of noodle strings with different thicknesses from sticking together.

Furthermore, the noodle cutting device 200 in this embodiment scrapes out multiple types of noodle strings of different thicknesses at two different scraping positions on each cutting blade roll, which makes it possible to reduce (disperse) the number of noodle strings contained in the scraped out noodle string bundle, and since the behavior of each noodle string bundle scraped out from each scraping position differs, it is possible to prevent the noodle strings from overlapping in a linear or planar shape.
Furthermore, the noodle making cutting device 200 in this embodiment cuts out multiple types of noodle strands of different thicknesses even for the noodle strand bundles at each scraping position, so that the behavior of each noodle strand of each thickness is different, including differences in the direction and degree of curvature, and since the noodle strands are scraped out from every other insertion portion, the distance between adjacent noodle strands can be increased and the noodle strands can be prevented from overlapping in a linear or planar shape.
As a result, the noodle cutting device 200 in this embodiment can prevent multiple types of noodle strings with different thicknesses from sticking together.

Next, the operation of the noodle-making cutting device 200 and the state of the raw noodle strings 3 cut by the noodle-making cutting device 200 during the manufacturing process will be described with reference to FIG. 5 to FIG.
10 , the noodle sheet forming unit 100 (rolling rolls 101, 102, 103) sequentially rolls out thin noodle sheets formed from noodle dough produced by a multifunction machine (not shown) or the like. The thin noodle sheet 2 produced by the noodle sheet forming unit 100 is fed into the noodle cutting device 200.

The noodle-making cutting device 200 cuts out the noodle band 2 to form a plurality of raw noodle strings 3. The operation of the noodle-making cutting device 200 will be described in detail below.
5, the first cutting blade roll 210 and the second cutting blade roll 230 are disposed so as to mesh with each other at a meshing position K. In this embodiment, the meshing position K is formed on a plane including the first rotation axis C1 and the second rotation axis C2.

At the meshing position K, each of the multiple first pushing portions 212 of the first cutting blade roll 210 is meshed with each of the multiple third fitting portions 236 and the multiple fourth fitting portions 246 of the second cutting blade roll 230 .
Similarly, at the meshing position K, each of the second pushing-in portions 232 of the second cutting blade roll 230 is in a meshed state with each of the first fitting portions 216 and the second fitting portions 226 of the first cutting blade roll 210. By forming the meshed state as described above, the noodle band 2 is sheared into a plurality of raw noodle strands 3.

The noodle band 2 fed into the meshing position K between the first cutting blade roll 210 and the second cutting blade roll 230 in the noodle cutting device 200 is sheared (cut) into multiple raw noodle strings 3 at the meshing position K. The noodle band 2 is then sheared and pushed into the multiple third insertion portions 236 and the multiple fourth insertion portions 246 of the second cutting blade roll 230 by the multiple first pushing portions 212 of the first cutting blade roll 210. Similarly, the noodle band 2 is sheared and pushed into the multiple first insertion portions 216 and the multiple second insertion portions 226 of the first cutting blade roll 210 by the multiple second pushing portions 232 of the second cutting blade roll 230.

The raw noodle strings 3 pressed into each insertion portion are scraped out by each scraping body (scraping portion, scraping teeth) which will be described later.
1 and 10 , the first cutting blade roll 210, with the multiple raw noodle strings 3 fitted into the first fitting portion 216 and the second fitting portion 226, is rotated in a first rotation direction R1 about a first rotation axis C1. Of the raw noodle strings 3 that are rotationally moved in conjunction with the rotation of the first cutting blade roll 210, the raw noodle strings 3 that are fitted into the first fitting portion 216 are scraped out by a first scraping portion 251 of the first scraping body 250 at a first scraping-out position T1.
Next, the remaining raw noodle strings 3 that have been rotated and moved in conjunction with the rotation of the first cutting blade roll 210 and that have entered the second insertion portion 226 are scraped out by the second scraping portion 256 of the first scraping body 250 at the second scraping-out position T2.

6 to 8, each of the raw noodle strings 3 fitted into the first fitting portions 216 is scraped out at the first scraping position T1 by the first scraping teeth 252 (first scraping tooth group 252A) of the first scraping portion 251. In detail, each of the raw noodle strings 3 fitted into the first fitting portions 216 is scraped out at the first scraping position T1 by the first narrow scraping tooth 253 and the first wide scraping tooth 254 included in the first scraping tooth group 252A of the first scraping portion 251.
The raw noodle strings 3 scraped out by the first scraping unit 251 hang down vertically downward due to their own weight.

6 to 8, each of the raw noodle strings 3 fitted into the second fitting portions 226 is scraped out at the second scraping position T2 by the second scraping teeth 257 (second scraping tooth group 257A) of the second scraping portion 256. In detail, each of the raw noodle strings 3 fitted into the second fitting portions 226 is scraped out at the second scraping position T2 by the second narrow scraping tooth 258 and the second wide scraping tooth 259 included in the second scraping tooth group 257A of the second scraping portion 256.
The raw noodle strings 3 scraped out by the second scraping unit 256 hang down vertically downward due to their own weight.

The second cutting blade roll 230, with the multiple raw noodle strings 3 fitted into the third fitting portion 236 and the fourth fitting portion 246, is rotated in a second rotation direction R2 about the second rotation axis C2. Of the raw noodle strings 3 that are rotationally moved in conjunction with the rotation of the second cutting blade roll 230, the raw noodle strings 3 that are fitted into the third fitting portion 236 are scraped out by the third scraping portion 261 of the second scraping body 260 at the third scraping-out position T3.
Next, of the raw noodle strings 3 that have been rotationally moved in conjunction with the rotation of the second cutting blade roll 230, the remaining raw noodle strings 3 that have entered the fourth insertion portion 246 are scraped out by the fourth scraping portion 266 of the second scraper body 260 at the fourth scraping position T4. Here, the positional relationship between the second cutting blade roll 230 and the scraping teeth of the second scraper body 260 and the behavior of the raw noodle strings 3 are similar to the positional relationship and behavior between the first cutting blade roll 210 and the scraping teeth of the first scraper body 250, and therefore will not be described here.

As shown in FIG. 10, the cut raw noodle strings 3 are stacked in four layers downward from the raw noodle strings 3 whose scraping position is on the upstream side of the belt 410. Since the raw noodle strings 3 in each layer are scraped out at two different scraping positions on each cutting blade roll, the number of noodle strings contained in each scraped out noodle string bundle (each layer) can be reduced (dispersed), the behavior of each noodle string bundle (each layer) scraped out from each scraping position is different, since multiple types of noodle strings with different thicknesses are cut out, the behavior of each noodle string with each thickness is different, including differences in the direction and degree of curvature, and since the noodle strings are scraped out from every other insertion portion, the distance between adjacent noodle strings can be increased, etc., which prevents the raw noodle strings 3 from overlapping linearly or planarly. In the horizontal direction, the raw noodle strings 3 adjacent to each other are prevented from overlapping linearly, and in the vertical direction, the raw noodle strings 3 constituting each layer are prevented from overlapping planarly.

For example, as shown in FIG. 9, the raw noodle strings 3 cut out from the noodle-making cutting device 200 in this embodiment are not synchronized with each other and are stacked on the belt 410 of the transport conveyor 400 in a state in which they draw arcs roughly randomly. In contrast, the raw noodle strings 3 cut out from a conventional noodle-making cutting device are stacked on the belt 410 in synchronization with each other. In this case, adjacent raw noodle strings 3 overlap (stick together) in a linear or planar manner, and many of the layers in the vertical direction also overlap in a planar manner.

10 , the raw noodle strands 3 of different thicknesses cut out by the noodle-making cutter 200 in this embodiment are carried into the internal space 330 of the steaming device 300 as the belt 410 rotates. The raw noodle strands 3 of different thicknesses brought into the internal space 330 of the steaming device 300 are gelatinized by the high-temperature steam that fills the internal space 330.
Here, the noodle-making cutting device 200 of this embodiment prevents the raw noodle strings 3 from overlapping in a linear or planar shape, so they are less likely to stick together even when steamed (gelatinization treatment) in the steaming device 300 (even if they do stick together, it is in a dot-like state).

The multiple types of steamed noodle strands 4 of different thicknesses, which are formed by pregelatinizing the raw noodle strands 3, are cooled as necessary with cooling water sprayed from shower device 350, and then stretched in the downstream portion of the transport conveyor 400 while being transported by a tension conveyor 500 serving as a stretching section. Here, the cooling water sprayed from the shower device 350 prevents the noodle strands 4 from drying and sticking together. In addition to spraying cooling water from the shower device 350, the same effect can be obtained by immersing the noodle strands 4 in a specified immersion device.
As described above, in this embodiment, the steamed noodle strands 4 are prevented from sticking together, or even if they do stick together, they are only stuck together in dots, and therefore the steamed noodle strands 4 are suitably loosened in the stretching step.

The noodles are then passed through a cutting device that cuts them to a specified length to produce steamed noodles.
In addition, after cutting, the noodles can be passed through a predetermined drying device (e.g., a fryer, a hot air dryer, etc.) to produce instant noodles.

According to this embodiment, the noodle making cutting device 200 can cut out multiple types of noodle strings with different thicknesses and prevent the multiple types of noodle strings from sticking together. The noodle making cutting device 200 in this embodiment is configured to scrape out multiple types of noodle strings with different thicknesses at two different scraping positions on each cutting blade roll and scrape out noodle strings from every other insertion portion at each scraping position, so it is possible to prevent the multiple types of noodle strings with different thicknesses from sticking together.

In addition, according to this embodiment, the noodle cutting device 200 scrapes out multiple types of noodle strings with different thicknesses at two different scraping positions on each cutting blade roll, so the number of noodle strings contained in the scraped noodle string bundle can be reduced (dispersed), and since the behavior of each noodle string bundle scraped out from each scraping position is different, the noodle strings can be prevented from overlapping in a linear or planar shape.

In addition, according to this embodiment, the noodle making cutting device 200 cuts out multiple types of noodle strands with different thicknesses from the bundle of noodle strands at each scraping position, so that the behavior of each noodle strand is different, including differences in the direction and degree of curvature, and because the noodle strands are scraped out from every other insertion section, the distance between adjacent noodle strands can be increased, and the noodle strands can be prevented from overlapping in a linear or planar shape.

In addition, this embodiment makes it possible to obtain noodles that are easy to separate and prevent the noodle strings from sticking together without using a conduit or the like.

In addition, according to this embodiment, it is possible to obtain steamed noodles, instant noodles, buckwheat noodles, etc. that contain multiple types of linear noodle strands with different thicknesses. This makes it possible to obtain noodles that are easy to cook and have a texture and smooth throat feel that is similar to that of hand-cut noodles.

In addition, according to this embodiment, the noodle-making cutting device 200 can suppress linear or planar overlap (sticking) between the cut raw noodle strands 3. And because there is little linear or planar overlap, even if the noodle strands are subjected to a process such as steaming, which makes the noodle strands stick more firmly, the stuck parts can be easily peeled off by pulling the noodle strands, etc. Moreover, since no device that forms strong waves such as a conduit is attached, the noodle strands are relatively straight. According to this embodiment, it is possible to obtain noodles that are easy to cook and have a texture and smooth throat feel like those of hand-cut noodles.

Furthermore, as a method for cutting out noodle strings of different thicknesses, for example, all noodle strings scraped out at the first scraping position can be made thin (the fitting portion into which the scraping teeth of the first scraping part are inserted is made only the narrow portion) and all noodle strings scraped out at the second scraping position can be made thick (the fitting portion into which the scraping teeth of the second scraping part are inserted is made only the wide portion), but in this case, the state of the layered surface (the behavior of the noodle strings, for example, the shape of the curves (loops) and the spacing pattern) differs between layers, making them more likely to stick together. If the thickness of the noodle strings scraped out at each scraping position is the same, this is not preferable as they are more likely to stick together.
In contrast, in this embodiment, noodle strings of different thicknesses are scraped out at each scraping position, so the layered surface becomes uniform in each layer and sticking is less likely to occur. The noodle-making cutting device 200 in this embodiment scrapes out multiple types of noodle strings of different thicknesses in a mixed state at each scraping position, so it is possible to prevent the noodle strings from sticking together.

The present invention is not limited to the above-described embodiment, and modifications and improvements within the scope of the present invention that can achieve the object of the present invention are included in the present invention.
In this embodiment, the multiple insertion portions (group of insertion portions) in each cutting blade roll include two types of insertion portions with different widths, a narrow portion and a wide portion, but are not limited thereto, and may include one or more types of insertion portions with widths different from each narrow portion and each wide portion. All or some of the groups from the multiple first insertion portion groups to the multiple fourth insertion portion groups may include one or more types of insertion portions with widths different from each narrow portion and each wide portion. In this case, it is preferable that each narrow portion, each wide portion, and one or more types of insertion portions with different widths are arranged so that a predetermined arrangement pattern is repeated in each rotation axis direction in multiple sets.

For example, as shown in Fig. 11, in another embodiment of the noodle cutting device, the multiple fitting portions (fitting portion group) in each cutting blade roll may include three or more types of fitting portions with different widths. Fig. 11 is a diagram illustrating the meshing state between the first cutting blade roll and the second cutting blade roll in another embodiment.
11, the first cutting blade roll 210a has a first narrow portion 219a, a first wide portion 218a, and a first intermediate width portion 217a whose width is intermediate between the first narrow portion 219a and the first wide portion 218a. The first cutting blade roll 210a also has a second narrow portion 229a, a second wide portion 228a, and a second intermediate width portion 227a whose width is intermediate between the second narrow portion 229a and the second wide portion 228a.

The second cutting blade roll 230a also has a third narrow portion 339a, a third wide portion 338a, and a third intermediate width portion 337a whose width is intermediate between the third narrow portion 339a and the third wide portion 338a. The second cutting blade roll 230a also has a fourth narrow portion 349a, a fourth wide portion 348a, and a fourth intermediate width portion 347a whose width is intermediate between the fourth narrow portion 349a and the fourth wide portion 348a.

In addition, in this embodiment, the number of scraping positions for each cutting blade roll is two, but this is not limited to two and may be three or more. In this case, the number of scraping portions in each scraping body is three or more.

In addition, in this embodiment, the scraper that scrapes out the raw noodle strings is an integrated type in which the first scraper section and the second scraper section are integrated, but this is not limited to this, and for example, as shown in Figure 12, the first scraper section and the second scraper section may be independent. Figure 12 is a front view explaining the structure of a noodle cutting device in another embodiment.

For example, as shown in FIG. 12, another embodiment of a noodle cutting device 200A has a first scraper 250A arranged relative to a first cutting blade roll 212a, and a second scraper 250B independent of the first scraper 250A.
In addition, the noodle cutting device 200A has a third scraper 260A arranged relative to the second cutting blade roll 232a, and a fourth scraper 260B independent of the third scraper 260A.

The first scraping portion 250A is arranged such that the tip of the scraping tooth (scraping position) is positioned at a position 5° to 90°, preferably 30° to 90°, more preferably 45° to 90°, and particularly preferably 60° to 70° from the meshing position K in the first rotation direction R1 around the first rotation axis C1 (α).
In addition, the second scraping portion 250B is positioned at a position (12a) where the tip of the scraping tooth (scraping position) is 120° to 210°, and particularly preferably 150° to 180°, from the meshing position K in the first rotation direction R1 around the first rotation axis C1 (β).
In addition, it is preferable that the tip of the scraping tooth (scraping position) of the first scraping portion 250A and the tip of the scraping tooth (scraping position) of the second scraping portion 250B are positioned so as to be spaced apart by more than 90° in the first rotation direction R1 around the first rotation axis C1.
As a result, the raw noodle strings 3 scraped out at each scraping position are scraped out in behaviors that are significantly different from each other, and are prevented from overlapping in a linear or planar shape.

In addition, in this embodiment, in each group of insertion parts, the narrow and wide parts are arranged so that a predetermined arrangement pattern is repeated in multiple sets in each rotation axis direction, for example, the arrangement pattern of narrow parts, narrow parts, and wide parts is repeated in multiple sets in succession. In this embodiment, the narrow parts are arranged in succession, but if the narrow parts are arranged so that they are not continuous, sticking and the like are more suppressed. In the noodle cutting device, in each of the multiple first insertion part groups to the multiple fourth insertion part groups, the narrow parts are arranged so that they are not continuous in each rotation axis direction, and the wide parts are arranged so that they are not continuous in each rotation axis direction, which is preferable in terms of suppressing sticking and the like. Here, when there are two types of insertion parts with different widths, only an alternating arrangement pattern is available, and in some cases, it may not be optimal from the product perspective in terms of the desired texture and the like. When there are three or more types of insertion parts with different widths, the number of arrangement patterns increases, and a preferable mode can be selected in terms of both sticking and texture and the like.
