Description

Technical Field

[0001] The present invention relates to a noodle cutting device for cutting a noodle band into noodle strands by a cutting blade roll in noodle production, and a noodle production method using the noodle cutting device.

Background Art

[0002] Conventionally, the mainstream method for cutting noodle strands by a machine is to pass a noodle dough that has been rolled and thinned into a noodle band between a pair of opposing rotating cutting blade rolls and cut it into a linear shape. Each of this pair of cutting blade rolls has a plurality of annular convex portions formed in the circumferential direction and a plurality of annular concave portions (grooves) formed between the convex portions.

[0003] For example, in a square blade type cutting blade roll, a convex pushing portion (also called a peak) formed on one cutting blade roll is inserted into a concave fitting portion (also called a groove) of the other cutting blade roll to cut the noodle band. The cut noodle strands are pushed into the fitting portion side in a plurality of spaces formed by the meshing of the opposing cutting blade rolls, that is, the space formed by the pushing portion and the fitting portion.

[0004] The noodle strands pushed into the fitting portion (groove) rotate and move as the cutting blade roll rotates because they are in close contact with the side surface of the groove. The noodle strands in close contact with the side surface of the groove are scraped out of the groove by a serrated scraper (scraping portion, scraper) having comb-shaped teeth. Specifically, by inserting the tips of a plurality of teeth (scraping teeth) formed on the scraper into the groove, the noodle strands that rotate and move due to the rotation of the cutting blade roll are scraped out of the groove.

[0005] Normally, the thickness of the noodle strands is the same, but there is also so-called "irregularly cut noodles" that include noodle strands of different thicknesses. "Irregularly cut noodles" can give a feeling of difference in texture by including noodle strands of different thicknesses. "Irregularly cut noodles" can give a texture similar to hand-cut noodles.

[0006] As an apparatus for cutting out noodle strands of different thicknesses, an apparatus is disclosed that cuts out noodle strands so that the thickness of the noodle strands is different for each section in the longitudinal direction of a cutting blade roller (cutting blade roll) (for each fixed number of noodle strands) (see, for example, Patent Documents 1 and 2). Also, an apparatus is disclosed that makes the interval between cutting blades and / or the depth of recesses formed between cutting blades non-uniform, together with an apparatus that cuts out noodle strands so that the thickness of the noodle strands is different for each section in the longitudinal direction of a cutting blade roller (cutting blade roll) (for each fixed number of noodle strands) (see, for example, Patent Document 3).

[0007] Here, for fresh noodles, the noodle strands cut out in this way may be cut to a fixed length and dusted with flour so that the noodle strands do not stick together. However, in the case of mass-produced chilled noodles, frozen noodles, or instant noodles, it is necessary to convey the noodle strands cut out in this way by a conveyor and continuously steam or boil them to subject the noodle strands to gelatinization treatment.

[0008] However, when subjecting noodle strands to gelatinization treatment by steaming or boiling, since it takes a certain amount of time, the speed of the conveyor passing through a steam chamber for steaming or a boiling tank for boiling must be made considerably slower than the cutting speed when cutting out the noodle strands. On the other hand, in the cut-out noodle strands, adjacent or overlapping noodle strands may stick together during the gelatinization treatment or conveyance. Particularly, when gelatinizing noodle strands by steaming, the noodle strands significantly stick together.

[0009] When noodle strands stick together, the noodles may become dumpling-shaped without loosening during cooking or eating, or if forced to loosen, the noodle strands may be cut short. Also, there may be a disadvantage that the stuck-together part is not sufficiently gelatinized. Furthermore, in the case of instant noodles, the usually cut noodles are steamed and then dried for production. However, if the drying treatment such as deep-frying or hot-air drying is performed in the stuck-together state, the drying of that part is not sufficient and it remains raw, resulting in defective products.

[0010] In order to suppress such sticking, especially in the case of steamed noodles, the noodle strands cut out by a pair of opposing cutting blade rolls are waved (usually with fine and strong waves in the vertical direction) by passing them through a conduit or the like immediately after cutting, so as to prevent the noodle strands from sticking to each other linearly or in a planar manner as much as possible. That is, the contact area between the noodle strands is reduced so that they do not stick to each other.

[0011] However, when the waved noodle strands are steamed, the noodle strands are gelatinized in the waved state on the conveyor, so the noodle strands are fixed while having a strong wave shape. Therefore, even if a step of stretching (pulling) the noodle strands after steaming is added, the noodles will be in a shrunk state with the wave shape remaining. Here, raw noodles are generally straight except in special cases. In particular, in the case of buckwheat noodles, udon noodles, spaghetti, etc., shrunk noodles are strange and undesirable.

[0012] Although the demand for non-waved noodles is large, if the noodles are not waved, there is a problem that adjacent or overlapping noodle strands stick to each other as described above.

The widths, included ratios, and arrangements of the first narrow-width pressing portion 213A and the first wide-width pressing portion 213B are formed to correspond to the widths, included ratios, and arrangements of the third fitting portion 236 and the fourth fitting portion 246 in the second cutting blade roll 230 described later. A first fitting portion 216 or a second fitting portion 226 is arranged between the plurality of first pressing portions 212.

[0033] Each of the plurality of first fitting portions 216 and each of the plurality of second fitting portions 226 are concave portions formed in an annular shape along the circumferential direction on the outer surface of the first cutting blade roll 210. The plurality of first fitting portions 216 and the plurality of second fitting portions 226 are respectively formed between the plurality of first pressing portions 212.

[0034] The first fitting portion 216 and the second fitting portion 226 are alternately arranged in the direction of the first rotation axis C1. Each of the plurality of first fitting portions 216 is a fitting portion into which the raw noodle line 3 being fitted is scraped out at the first scraping position T1 by the first scraping portion 251 of the first scraping body 250. Each of the plurality of second fitting portions 226 is a fitting portion into which the raw noodle line 3 being fitted is scraped out at the second scraping position T2 by the second scraping portion 256 of the first scraping body 250.

[0035] Specifically, each of the plurality of first fitting portions 216 is a concave portion into which each of the plurality of first scraping teeth 252 in the first scraping portion 251 of the first scraping body 250 is inserted and arranged. Each of the plurality of first fitting portions 216 is a fitting portion into which the raw noodle line 3 being fitted is scraped out at the first scraping position T1 by each of the plurality of first scraping teeth 252 in the first scraping portion 251 of the first scraping body 250.

[0036] Each of the plurality of second insertion portions 226 is a concave portion into which each of the plurality of second scraping teeth 257 in the second scraping portion 256 of the first scraping body 250 is inserted and arranged. Each of the plurality of second insertion portions 226 is an insertion portion into which the raw noodle line 3 being inserted is scraped at the second scraping position T2 by each of the plurality of second scraping teeth 257 in the second scraping portion 256 of the first scraping body 250.

[0037] As shown in FIGS. 2 and 5, the plurality of first insertion portions 216 include a plurality of first narrow-width portions 217 and a plurality of first wide-width portions 218 that are wider in width than the first narrow-width portions 217 in the direction of the first rotation axis C1. The width of each of the plurality of first narrow-width portions 217 is generally set to 1 to 5 mm, for example, set to 1.15 to 3.3 mm, but is not limited thereto. The width of each of the plurality of first wide-width portions 218 is generally set to 1 to 5 mm and is set wider than the width of the first narrow-width portion 217. The numerical values and ratios of the width of the first narrow-width portion 217 and the width of the first wide-width portion 218 can be appropriately adjusted from viewpoints such as the required texture and suppression of the overlapping of the raw noodle line 3.

[0038] Also, in the first insertion portion group 216A which is a group of the plurality of first insertion portions 216, the first narrow-width portion 217 and the first wide-width portion 218 are arranged in a mixed manner at a ratio of 2:1, but are not limited thereto. For example, in the first insertion portion group 216A which is a group of the plurality of first insertion portions 216, the first narrow-width portion 217 and the first wide-width portion 218 are preferably arranged in a mixture at a ratio of 1:4 to 4:1. Also, in the first insertion portion group 216A, at least one of the first narrow-width portion 217 and the first wide-width portion 218 is arranged so as not to be continuous in the direction of the first rotation axis C1.

[0039] As shown in FIGS. 2 and 5, the plurality of second insertion portions 226 include a plurality of second narrow-width portions 227 and a plurality of second wide-width portions 228 that are wider in width than the second narrow-width portions 227 in the direction of the first rotation axis C1. The width of each of the plurality of second narrow portions 227 is generally set to 1 to 5 mm, for example, set to 1.15 to 3.3 mm, but is not limited thereto. The width of each of the plurality of second wide portions 228 is generally set to 1 to 5 mm, and is set wider than the width of the second narrow portion 227. The numerical values and ratios of the width of the second narrow portion 227 and the width of the second wide portion 228 can be appropriately adjusted from the viewpoints of the required texture and suppression of overlapping of the fresh noodle strands 3, etc.

[0040] Further, in the second fitting portion group 226A which is a group of the plurality of second fitting portions 226, the second narrow portion 227 and the second wide portion 228 are arranged in a mixed manner at a ratio of 2:1, but are not limited thereto. For example, in the second fitting portion group 226A which is a group of the plurality of second fitting portions 226, it is preferable that the second narrow portion 227 and the second wide portion 228 are arranged in a mixed manner at a ratio of 1:4 to 4:1. Also, in the second fitting portion group 226A, at least one of the second narrow portion 227 and the second wide portion 228 is arranged so as not to be continuous in the first rotation axis direction C1.

[0041] In the first fitting portion group 216A, it is preferable that the first narrow portion 217 and the first wide portion 218 are arranged so as to continuously repeat a plurality of sets of a predetermined arrangement pattern in the first rotation axis C1 direction. For example, in the present embodiment, the first narrow portion 217 and the first wide portion 218 are arranged so as to continuously repeat a plurality of sets of the arrangement pattern of the first narrow portion 217, the first narrow portion 217, and the first wide portion 218 in the first rotation axis C1 direction.

[0042] Further, in the second fitting portion group 226A, it is preferable that the second narrow portion 227 and the second wide portion 228 are arranged so as to continuously repeat a plurality of sets of a predetermined arrangement pattern in the first rotation axis C1 direction. For example, in the present embodiment, the second narrow portion 227 and the second wide portion 228 are arranged so as to continuously repeat a plurality of sets of the arrangement pattern of the second narrow portion 227, the second narrow portion 227, and the second wide portion 228 in the first rotation axis C1 direction.

[0043] By arranging the plurality of first fitting portions 216 (first narrow-width portions 217, first wide-width portions 218) and the plurality of second fitting portions 226 (second narrow-width portions 227, second wide-width portions 228) as described above, for example, when the raw noodle line 3 is distributed to each of a plurality of lanes divided in the direction of the first rotation axis C1, the types (different thicknesses) of the raw noodle lines included in the group of raw noodle lines distributed in each lane become uniform, which is preferable because it contributes to the uniformity of the quality in the product.

[0044] Also, a first depth, which is the length in a first diameter direction orthogonal to the first rotation axis C1 of the first fitting portion 216, is different from a second depth, which is the length in the first diameter direction of the second fitting portion 226. 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.

[0045] In the present embodiment, the raw noodle line 3 fitted in the first fitting portion 216 is scraped out at the first scraping position T1. The raw noodle line 3 scraped out at the first scraping position T1 collides with the first scraping portion 251 (first scraping teeth 252) so as to apply a force mainly in the vertically downward direction, and is scraped out so as to flow in the vertically downward direction. On the other hand, the raw noodle line 3 fitted in the second fitting portion 226 is scraped out at a second scraping position T2 on the downstream side in the first rotation direction R1 from the first scraping position T1. The raw noodle line 3 scraped out at the second scraping position T2 collides with the second scraping portion 256 (second scraping teeth 258) so as to apply forces in the vertically downward direction and the horizontal direction, and is scraped out so as to flow in the vertically downward direction.

[0046] To correspond to this, the second scraping portion 256 (second scraping teeth 258) is preferably inserted and arranged deeper into the fitting portion so as to resist the force (in the horizontal direction) applied by the raw noodle line 3 and to be able to firmly scrape out the raw noodle line 3 even when deformed by the force from the raw noodle line 3. Therefore, in the present embodiment, the second fitting portion 226 is formed such that the second depth of the second fitting portion 226 is deeper than the first depth of the first fitting portion 216.

[0047] Here, in the present embodiment, the second depth of the second fitting portion 226 is configured to be deeper than the first depth of the first fitting portion 216, but it is not limited thereto. By adjusting the material, shape, and structure of the first grooving portion 251 (first scraping teeth 252) and the second grooving portion 256 (second scraping teeth 258), the second depth of the second fitting portion 226 and the first depth of the first fitting portion 216 may be configured to be the same depth.

[0048] Also, as described above, the first fitting portion 216 and the second fitting portion 226 are alternately arranged in the direction of the first rotation axis C1. Therefore, in the direction of the first rotation axis C1, the fitting portions with the first depth (shallow fitting portions) and the fitting portions with the second depth (deep fitting portions) are alternately arranged.

Each of the plurality of second pressing portions 232 is a portion that shears the noodle strip 2 and pushes the sheared noodle strip 2 (raw noodle line 3) into each of the plurality of first fitting portions 216 and the plurality of second fitting portions 226 formed in the first cutting blade roll 210. Also, each of the plurality of third fitting portions 236 and the plurality of fourth fitting portions 246 is a portion into which the sheared noodle strip 2 (raw noodle line 3) is pushed and fitted by the plurality of first pressing portions 212 formed in the first cutting blade roll 210.

[0050] Each of the plurality of 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 plurality of second pressing portions 232 is formed at a predetermined interval in the direction of the second rotation axis C2. The plurality of second pressing portions 232 includes a second narrow-width pressing portion 233A and a second wide-width pressing portion 233B that is wider than the second narrow-width pressing portion 233A in the length in the direction of the second rotation axis C2. The widths, included ratios, and arrangements in the second narrow-width pressing portion 233A and the second wide-width pressing portion 233B are formed to correspond to the widths, included ratios, and arrangements in the first fitting portion 216 and the second fitting portion 226 in the first cutting-edge roll 210. A third fitting portion 236 or a fourth fitting portion 246 is arranged between the plurality of second pressing portions 232.

[0051] Each of the plurality of third fitting portions 236 and each of the plurality of fourth fitting portions 246 is a concave portion formed annularly along the circumferential direction on the outer surface of the second cutting-edge roll 230. The plurality of third fitting portions 236 and the plurality of fourth fitting portions 246 are respectively formed between the plurality of second pressing portions 232.

[0052] The third fitting portion 236 and the fourth fitting portion 246 are alternately arranged in the direction of the second rotation axis C2. Each of the plurality of third fitting portions 236 is a fitting portion into which the raw noodle line 3 being fitted is scraped out at the third scraping position T3 by the third scraping portion 261 of the second scraping body 260. Each of the plurality of fourth fitting portions 246 is a fitting portion into which the raw noodle line 3 being fitted is scraped out at the fourth scraping position T4 by the fourth scraping portion 266 of the second scraping body 260.

[0053] Specifically, each of the plurality of third fitting portions 236 is a concave portion into which each of the plurality of third scraping teeth in the third scraping portion 261 of the second scraping body 260 is inserted and arranged. Each of the plurality of third fitting portions is a fitting portion into which the raw noodle line 3 being fitted is scraped out at the third scraping position T3 by each of the plurality of third scraping teeth in the third scraping portion 261 of the second scraping body 260.

[0054] Each of the plurality of fourth insertion portions 246 is a concave portion into which each of the plurality of fourth scraping teeth in the fourth scraping portion 266 of the second serrated body 260 is inserted and arranged. Each of the plurality of fourth insertion portions is an insertion portion into which the raw noodle line 3 being inserted is scraped at the fourth scraping position T4 by each of the plurality of fourth scraping teeth in the fourth scraping portion 266 of the second serrated body 260.

[0055] As shown in FIGS. 2 and 5, the plurality of third insertion portions 236 include a plurality of third narrow portions 237 and a plurality of third wide portions 238 that are wider in width than the third narrow portions 237 in the direction of the second rotation axis C2. The width of each of the plurality of third narrow portions 237 is generally set to 1 to 5 mm, for example, 1.15 to 3.3 mm, but is not limited thereto. The width of each of the plurality of third wide portions 238 is generally set to 1 to 5 mm and is set wider than the width of the third narrow portion 237. The numerical values and ratios of the width of the third narrow portion 237 and the width of the third wide portion 238 can be appropriately adjusted from the viewpoints of the required texture and suppression of the overlap of the raw noodle line 3.

[0056] Also, in the third insertion portion group 236A which is a group of the plurality of third insertion portions 236, the third narrow portion 237 and the third wide portion 238 are arranged in a mixed manner at a ratio of 2:1, but are not limited thereto. For example, in the third insertion portion group 236A which is a group of the plurality of third insertion portions 236, the third narrow portion 237 and the third wide portion 238 are preferably arranged in a mixture at a ratio of 1:4 to 4:1. Also, in the third insertion portion 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 direction of the second rotation axis C2.

[0057] As shown in FIGS. 2 and 5, the plurality of fourth insertion portions 246 include a plurality of fourth narrow portions 247 and a plurality of fourth wide portions 248 that are wider in width than the fourth narrow portions 247 in the direction of the second rotation axis C2. The width of each of the plurality of fourth narrow portions 247 is generally set to 1 to 5 mm, for example, set to 1.15 to 3.3 mm, but is not limited thereto. The width of each of the plurality of fourth wide portions 248 is generally set to 1 to 5 mm, and is set wider than the width of the fourth narrow portion 247. The numerical values and ratios of the width of the fourth narrow portion 247 and the width of the fourth wide portion 248 can be appropriately adjusted from the viewpoints of the required texture, suppression of overlap of the fresh noodle strands 3, and the like.

[0058] Further, in the fourth insertion portion group 246A which is a group of the plurality of fourth insertion portions 246, the fourth narrow portion 247 and the fourth wide portion 248 are mixed and arranged at a ratio of 2:1, but are not limited thereto. For example, in the fourth insertion portion group 246A which is a group of the plurality of fourth insertion portions 246, it is preferable that the fourth narrow portion 247 and the fourth wide portion 248 are mixed and arranged at a ratio of 1:4 to 4:1. Further, in the fourth insertion portion 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 direction.

[0059] In the third insertion portion group 236A, it is preferable that the third narrow portion 237 and the third wide portion 238 are arranged so as to continuously repeat a plurality of sets of a predetermined arrangement pattern in the third rotation axis C3 direction. For example, in the present embodiment, the third narrow portion 237 and the third wide portion 238 are arranged so as to continuously repeat a plurality of sets of the arrangement pattern of the third narrow portion 237, the third narrow portion 237, and the third wide portion 238 in the second rotation axis C2 direction.

[0060] Further, in the fourth insertion portion group 246A, it is preferable that the fourth narrow portion 247 and the fourth wide portion 248 are arranged so as to continuously repeat a plurality of sets of a predetermined arrangement pattern in the second rotation axis C2 direction. For example, in the present embodiment, the fourth narrow portion 247 and the fourth wide portion 248 are arranged so as to continuously repeat a plurality of sets of the arrangement pattern of the fourth narrow portion 247, the fourth narrow portion 247, and the fourth wide portion 248 in the second rotation axis C2 direction.

[0061] By arranging the plurality of third fitting portions 236 (third narrow portions 237, third wide portions 238) and the plurality of fourth fitting portions 246 (fourth narrow portions 247, fourth wide portions 248) as described above, for example, when the raw noodle line 3 is distributed to each of a plurality of lanes divided in the direction of the second rotation axis C2, the types (different thicknesses) of the raw noodle lines included in the group of raw noodle lines distributed in each lane become uniform, which is preferable because it contributes to the uniformity of the quality in the product.

[0062] Also, the third depth, which is the length in the second diameter direction orthogonal to the second rotation axis C2 of the third fitting portion 236, is different from the third depth, which is the length in the second diameter direction of the fourth fitting portion 246. 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.

[0063] In the present embodiment, the raw noodle line 3 fitted into the third fitting portion 236 is scraped out at the third scraping position T3. The raw noodle line 3 scraped out at the third scraping position T3 hits against the third scraping portion 261 (third scraping teeth) so as to mainly apply a force in the vertically downward direction, and is scraped out so as to flow in the vertically downward direction. On the other hand, the raw noodle line 3 fitted into the fourth fitting portion 246 is scraped out at the fourth scraping position T4 on the downstream side in the second rotation direction R2 from the third scraping position T3. The raw noodle line 3 scraped out at the fourth scraping position T4 hits against the fourth scraping portion 266 (fourth scraping teeth) so as to apply forces in the vertically downward direction and the horizontal direction, and is scraped out so as to flow in the vertically downward direction.

[0064] To correspond to this, the fourth scraping portion 266 (fourth scraping teeth) resists the force (in the horizontal direction) applied by the raw noodle line 3, and is preferably inserted and arranged in the fitting portion to a deeper position so that the raw noodle line 3 can be firmly scraped out even when deformed by the force from the raw noodle line 3. Therefore, in the present embodiment, the fourth fitting portion 246 is formed such that the fourth depth of the fourth fitting portion 246 is deeper than the third depth of the third fitting portion 236.

[0065] Here, in the present embodiment, the fourth depth of the fourth fitting portion 246 is configured to be deeper than the third depth of the third fitting portion 236. However, the present invention is not limited to this. By adjusting the material, shape, and structure of the third grooving portion 261 (third scraping teeth) and the fourth grooving portion 266 (fourth scraping teeth), the fourth depth of the fourth fitting portion 246 and the fourth depth of the third fitting portion 236 may be configured to be the same depth.

[0066] Also, as described above, the third fitting portion 236 and the fourth fitting portion 246 are alternately arranged in the direction of the second rotation axis C2. Therefore, in the direction of the second rotation axis C2, the fitting portions with the third depth (shallow fitting portions) and the fitting portions with the fourth depth (deep fitting portions) are alternately arranged.

[0067] As shown in FIG. 1, the first grooving body 250 is attached to the first cutting blade roll 210. The first grooving body 250 is attached to the housing by a mounting member 291 inserted through a mounting hole 281 on the lower side of the first cutting blade roll 210. The second grooving body 260 is attached to the second cutting blade roll 230. The second grooving body 260 is attached to the housing by a mounting member 292 inserted through a mounting hole 282 on the lower side of the second cutting blade roll 230.

[0068] Each grooving body is attached such that the angle formed by the tip of the scraping teeth and the tangent, which is the contact angle with respect to each cutting blade roll, is in the range of, for example, 10° to 60°. The installation position of each grooving body is preferably adjusted so that the contact angle is set within the above range, the raw noodle line can be easily scraped out, and the tip of the grooving body is less likely to be worn. Hereinafter, the arrangement, shape, etc. of the first grooving body 250 attached to the first cutting blade roll 210 will be mainly described. However, the arrangement, shape, etc. of the second grooving body 260 attached to the second cutting blade roll 230 are the same, and the description of the first grooving body 250 can be applied.

[0069] As shown in FIGS. 1 and 3, the first serrated body 250 has a first serrated portion 251, a second serrated portion 256, and the above-described mounting hole 281. The first serrated body 250 is a serrated body in which the first serrated portion 251 and the second serrated portion 256 are integrally formed, and the raw noodle line 3 is scraped out at two scraping positions.

[0072] The plurality of first scraping teeth 252 include a plurality of first narrow scraping teeth 253 and a plurality of first wide scraping teeth 254. The first narrow scraping tooth 253 is a scraping tooth that is inserted into the first narrow portion 217 on 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 on 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.

[0073] The second scraping portion 256 is a portion that scrapes the raw noodle line 3 at a second scraping position T2 on the downstream side 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 and arranged in a plurality of second insertion portions 226 at a second scraping position T2 different from the first scraping position T1 on the first cutting blade roll 210.

[0074] The plurality of second scraping teeth 257 are scraping teeth that are shorter than the above-described first scraping teeth 252. The plurality of second scraping teeth 257 are formed such that their roots are bent toward the first cutting blade roll 210 side (upward). The plurality of second scraping teeth 257 are adjusted to have a shape suitable for scraping the raw noodle line 3 and flowing it in the vertical direction.

[0075] The plurality of second scraping teeth 257 include a plurality of second narrow scraping teeth 258 and a plurality of second wide scraping teeth 259. The second narrow scraping tooth 258 is a scraping tooth that is inserted into the second narrow portion 227 on 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 on 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.

[0076] As shown in FIGS. 1 and 3, the second scraping body 260 has a third scraping portion, a fourth scraping portion 266, and a mounting hole. Similar to the first scraping body 250, the second scraping body 260 is a scraping body in which the third scraping portion 261 and the fourth scraping portion 266 are integrally formed and scrape the raw noodle line 3 at two scraping positions. The second scraping body 260 is an integral scraping body having a third scraping portion 261 that scrapes the raw noodle line 3 at a third scraping position T3 and a fourth scraping portion 266 that scrapes the raw noodle line 3 at a fourth scraping position T4.

[0077] The third scraping portion 261 is a portion that scrapes the raw noodle line 3 at the 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 and arranged in a plurality of third insertion portions 236 at the third scraping position T3 on the second cutting blade roll 230.

[0078] The fourth scraping portion 266 is a portion that scrapes the raw noodle line 3 at the fourth scraping position T4 on the downstream side 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 and arranged in a plurality of fourth insertion portions 246 at a fourth scraping position T4 different from the third scraping position T3 on the second cutting blade roll 230.

[0079] Here, for the shapes, structures, etc. of the third scraping teeth and the fourth scraping teeth, the descriptions of the above-mentioned first scraping teeth 252 and second scraping teeth 257 are incorporated by reference.

[0080] The noodle cutting device 200 for noodle making in the present embodiment can cut out a plurality of types of noodle lines with different thicknesses and can suppress the binding between the plurality of types of noodle lines with different thicknesses. The noodle cutting device 200 for noodle making in the present embodiment is configured to scrape out a plurality of types of noodle lines with different thicknesses at two different scraping positions on each cutting blade roll, and to scrape out the noodle lines from every other insertion portion at each scraping position. Therefore, it is possible to suppress the binding between the plurality of types of noodle lines with different thicknesses.

[0081] In addition, since the noodle cutting device 200 for noodle making in the present embodiment scrapes out a plurality of types of noodle lines with different thicknesses at two different scraping positions on each cutting blade roll, the number of noodle lines included in the scraped noodle line bundle can be reduced (dispersed). Moreover, since the behaviors of the noodle line bundles scraped out from each scraping position are different, it is possible to suppress the noodle lines from overlapping linearly or in a planar shape. In addition, since the noodle cutting device 200 for noodle production in the present embodiment cuts out a plurality of types of noodle strands having different thicknesses even in the noodle strand bundles at each scraping position, the behavior including differences in the direction and degree of curvature, etc. is different for each noodle strand of each thickness. Also, since the noodle strands are scraped out from every other fitting portion, the distance between adjacent noodle strands can be increased, and it is possible to suppress the noodle strands from overlapping linearly or in a planar manner. As a result, the noodle cutting device 200 for noodle production in the present embodiment can suppress the binding of a plurality of types of noodle strands having different thicknesses.

[0082] Subsequently, with reference to FIGS. 5 to 10, the operation of the noodle cutting device 200 for noodle production and the state during the manufacturing process of the raw noodle strands 3 cut out by the noodle cutting device 200 for noodle production will be described. First, as shown in FIG. 10, the noodle belt generating unit 100 (rolling rolls 101, 102, 103) sequentially performs a thinning rolling process on the noodle dough that has been formed into a noodle belt by a composite machine (not shown) or the like. The thin noodle belt 2 generated by the noodle belt generating unit 100 is fed into the noodle cutting device 200 for noodle production.

[0083] The noodle cutting device 200 for noodle production cuts out the noodle belt 2 to form a plurality of raw noodle strands 3. Hereinafter, the operation of the noodle cutting device 200 for noodle production will be described in detail. As shown in FIG. 5, the first cutting blade roll 210 and the second cutting blade roll 230 are arranged to mesh at the meshing position K. In the present embodiment, the meshing position K is formed on a plane including the first rotation axis C1 and the second rotation axis C2.

[0084] At the meshing position K, each of the plurality of first pushing portions 212 on the first cutting blade roll 210 and each of the plurality of third fitting portions 236 and the plurality of fourth fitting portions 246 on the second cutting blade roll 230 are in a meshed state. Similarly, at the meshing position K, each of the plurality of second pushing portions 232 on the second cutting blade roll 230 and each of the plurality of first fitting portions 216 and the plurality of second fitting portions 226 on the first cutting blade roll 210 are in a meshed state. By forming the meshing state as described above, the noodle belt 2 is sheared into a plurality of raw noodle strands 3.

[0085] The noodle strip 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 for noodle making is sheared (cut) into a plurality of raw noodle strands 3 at the meshing position K. Then, while the noodle strip 2 is being sheared, it is pushed into a plurality of third fitting portions 236 and a plurality of fourth fitting portions 246 in the second cutting blade roll 230 by the respective plurality of first pushing portions 212 in the first cutting blade roll 210. Similarly, while the noodle strip 2 is being sheared, it is pushed into a plurality of first fitting portions 216 and a plurality of second fitting portions 226 in the first cutting blade roll 210 by the respective plurality of second pushing portions 232 in the second cutting blade roll 230.

[0086] The raw noodle strands 3 pushed into each fitting portion are scraped out by respective scraping members (scraping portions, scraping teeth) described later. As shown in FIGS. 1 and 10, the first cutting blade roll 210 into which a plurality of raw noodle strands 3 are fitted in the first fitting portions 216 and the second fitting portions 226 is rotated in a first rotation direction R1 about a first rotation axis C1. Among the raw noodle strands 3 rotationally moved with the rotation of the first cutting blade roll 210, the raw noodle strands 3 fitted in the first fitting portions 216 are scraped out by a first scraping portion 251 in a first scraping member 250 at a first scraping position T1. Subsequently, among the raw noodle strands 3 rotationally moved with the rotation of the first cutting blade roll 210, the remaining raw noodle strands 3 fitted in the second fitting portions 226 are scraped out by a second scraping portion 256 in the first scraping member 250 at a second scraping position T2.

[0087] Specifically, as shown in FIGS. 6 to 8, each of the plurality of raw noodle strands 3 fitted in the plurality of first fitting portions 216 is scraped out at the first scraping position T1 by a plurality of first scraping teeth 252 (first scraping tooth group 252A) in the first scraping portion 251. In detail, each of the plurality of raw noodle strands 3 fitted in the plurality of first fitting portions 216 is scraped out at the first scraping position T1 by a first narrow-width scraping tooth 253 and a first wide-width scraping tooth 254 included in the first scraping tooth group 252A in the first scraping portion 251. The raw noodle strands 3 scraped out by the first scraping part 251 hang vertically downward due to their own weight.

[0088] Similarly, as shown in FIGS. 6 to 8, each of the plurality of raw noodle strands 3 fitted into the plurality of second fitting parts 226 is scraped out at the second scraping position T2 by a plurality of second scraping teeth 257 (second scraping tooth group 257A) in the second scraping part 256. Specifically, each of the plurality of raw noodle strands 3 fitted into the plurality of second fitting parts 226 is scraped out at the second scraping position T2 by the second narrow-width scraping teeth 258 and the second wide-width scraping teeth 259 included in the second scraping tooth group 257A in the second scraping part 256. The raw noodle strands 3 scraped out by the second scraping part 256 hang vertically downward due to their own weight.

[0089] The second cutting blade roll 230 into which the plurality of raw noodle strands 3 are fitted into the third fitting part 236 and the fourth fitting part 246 is rotated in the second rotation direction R2 about the second rotation axis C2. Among the raw noodle strands 3 that are rotationally moved along with the rotation of the second cutting blade roll 230 and are fitted into the third fitting part 236, the raw noodle strands 3 are scraped out at the third scraping position T3 by a third scraping part 261 in the second scraping body 260. Subsequently, among the raw noodle strands 3 that are rotationally moved along with the rotation of the second cutting blade roll 230 and are fitted into the remaining fourth fitting part 246, the raw noodle strands 3 are scraped out at the fourth scraping position T4 by a fourth scraping part 266 in the second scraping body 260. Here, the positional relationship between the second cutting blade roll 230 and the scraping teeth in the second scraping body 260 and the behavior of the raw noodle strands 3 are the same as the positional relationship and behavior, etc. between the first cutting blade roll 210 and the scraping teeth in the first scraping body 250, so the description is omitted.

[0090] As shown in FIG. 10, the cut fresh noodle strands 3 are stacked in four layers downward from the fresh noodle strands 3 whose scraping position is on the upstream side of the belt 410. Since a plurality of types of noodle strands with different thicknesses are scraped out at two different scraping positions on each cutting blade roll in each layer, it is possible to reduce (disperse) the number of noodle strands included in each scraped noodle strand bundle (each layer). The behavior of each noodle strand bundle (each layer) scraped out from each scraping position is different. Since a plurality of types of noodle strands with different thicknesses are cut out, the behavior including differences in the direction and degree of curvature, etc. is different for each thickness of noodle strand. Since the noodle strands are scraped out from every other fitting portion, the distance between adjacent noodle strands can be increased, etc., so that overlapping in a linear or planar shape is suppressed. Horizontally, overlapping with adjacent fresh noodle strands 3 in a linear shape is suppressed, and vertically, overlapping of the fresh noodle strands 3 constituting each layer in a planar shape is suppressed.

[0091] For example, as shown in FIG. 9, the fresh noodle strands 3 cut out from the noodle cutting device 200 in the present embodiment are not synchronized with each other and are stacked on the belt 410 of the conveyor 400 in a state of generally drawing arcs separately. On the other hand, the fresh noodle strands 3 cut out from a conventional noodle cutting device are stacked on the belt 410 in synchronization with each other. In this case, adjacent fresh noodle strands 3 overlap (stick together) in a linear or planar shape, and most of the layers in the vertical direction also overlap in a planar shape.

[0092] Also, as shown in FIG. 10, a plurality of types of fresh noodle strands 3 with different thicknesses cut out from the noodle cutting device 200 in the present embodiment are carried into the internal space 330 of the steaming device 300 as the belt 410 rotates. The plurality of types of fresh noodle strands 3 with different thicknesses carried into the internal space 330 of the steaming device 300 are gelatinized by the high-temperature steam filling the internal space 330. Here, since the fresh noodle strands 3 are suppressed from overlapping in a linear or planar shape by the noodle cutting device 200 of the present embodiment, binding is also less likely to occur (even if bound, it is in a dot-like state) during steaming (gelatinization treatment) in the steaming device 300.

[0093] Then, the plurality of types of steamed noodle strands 4 with different thicknesses after the raw noodle strands 3 are gelatinized are cooled by the cooling water radiated from the shower device 350 if necessary, and then stretched in the downstream part of the conveyor 400 while being conveyed by the tension conveyor 500 as the stretching part. Here, the cooling water radiated from the shower device 350 suppresses the drying and binding of the noodle strands 4. In addition to radiating the cooling water from the shower device 350, a similar effect can also be obtained by immersing the noodle strands 4 with a predetermined immersion device. As described above, in this embodiment, since the binding in the steamed noodle strands 4 is suppressed, or even if they are bound, they are only point-bonded, the steamed noodle strands 4 are preferably loosened in the stretching process.

[0094] After that, steamed noodles can be produced by passing through a cutting device that cuts to a predetermined length. In addition, instant noodles can be produced by passing through a predetermined drying device (for example, a fryer, a hot air dryer, etc.) after cutting.

[0095] According to this embodiment, the noodle cutting device 200 for noodle making can cut out a plurality of types of noodle strands with different thicknesses and can suppress the binding between the plurality of types of noodle strands with different thicknesses. The noodle cutting device 200 in this embodiment is configured to scrape out a plurality of types of noodle strands with different thicknesses at two different scraping positions on each cutting blade roll, and to scrape out the noodle strands from every other fitting part at each scraping position. Therefore, it is possible to suppress the binding between the plurality of types of noodle strands with different thicknesses.

[0096] Further, according to this embodiment, since the noodle cutting device 200 for noodle making scrapes out a plurality of types of noodle strands with different thicknesses at two different scraping positions on each cutting blade roll, the number of noodle strands included in the scraped noodle strand bundle can be reduced (dispersed), and since the behaviors of the noodle strand bundles scraped out from each scraping position are different, it is possible to suppress the overlapping of the noodle strands in a linear or planar shape.

[0097] Moreover, according to the present embodiment, since the noodle cutting device 200 for noodle making cuts out a plurality of types of noodle strands with different thicknesses even in the noodle strand bundle for each scraping position, the behavior including differences in the direction and degree of curvature, etc. is different for each noodle strand of each thickness, and since the noodle strands are scraped out from every other insertion portion, the distance between adjacent noodle strands can be increased, and it is possible to suppress the noodle strands from overlapping linearly or in a planar manner.

[0098] Moreover, according to the present embodiment, it is possible to obtain loose noodles with suppressed binding between noodle strands without using conduits or the like.

[0099] Moreover, according to the present embodiment, it is possible to obtain steamed noodles, instant noodles, soba noodles, etc. that include a plurality of types of noodle strands with different linear thicknesses. As a result, it is possible to obtain noodles that are easy to cook, have a texture like hand-cut noodles, and are easy to swallow.

[0100] Moreover, according to the present embodiment, the noodle cutting device 200 for noodle making can suppress the linear or planar overlap (sticking) of the cut raw noodle strands 3. And because there is little linear or planar overlap, even if a treatment such as steaming is performed to make the binding stronger, the binding portion can be easily peeled off by pulling the noodle strands. Moreover, since no device for forming a strong wave like a conduit is attached, the noodle strands are relatively straight. According to the present embodiment, it is possible to obtain noodles that are easy to cook, have a texture like hand-cut noodles, and are easy to swallow.

[0101] As a method of cutting out noodle strands with different thicknesses, for example, all the noodle strands scraped out at the first scraping position can be made thinner (the insertion portion into which the scraping teeth of the first scraping portion are inserted is only the narrow portion), and all the noodle strands scraped out at the second scraping position can be made thicker (the insertion portion into which the scraping teeth of the second scraping portion are inserted is only the wide portion). However, in this case, since the state of the laminated surface (the behavior of the noodle strands, for example, the shape of the curve (loop) and the pattern of the intervals) is different for each layer, binding is likely to occur. When the thickness of the noodle strands scraped out for each scraping position is the same, binding is likely to occur, which is not preferable. In contrast, in the present embodiment, since noodle strands with different thicknesses are mixed and scraped out at each scraping position, the laminated surface becomes homogeneous in each layer, making it difficult for binding to occur. The noodle cutting device 200 for noodle production in the present embodiment scrapes out a plurality of types of noodle strands with different thicknesses in a mixed state at each scraping position, so that binding between the noodle strands can be suppressed.

[0102] The present invention is not limited to the above-described embodiments, and modifications, improvements, etc. within the scope that can achieve the object of the present invention are included in the present invention. In the present embodiment, the plurality of fitting portions (fitting portion groups) in each cutting blade roll include a narrow-width portion and a wide-width portion, which are two types of fitting portions with different widths, but are not limited thereto. Each narrow-width portion and each wide-width portion may include one or a plurality of fitting portions with different widths. All or part of the groups from the group of the plurality of first fitting portions to the group of the plurality of fourth fitting portions may include one or a plurality of fitting portions with different widths from each narrow-width portion and each wide-width portion. Further, in this case, it is preferable that each narrow-width portion, each wide-width portion, and one or a plurality of fitting portions with different widths are arranged so as to continuously repeat a plurality of sets of a predetermined arrangement pattern in each rotation axis direction.

[0103] For example, as shown in FIG. 11, in a noodle cutting device according to another embodiment, the plurality of fitting portions (fitting portion groups) in each cutting blade roll may include three or more types of fitting portions with different widths. FIG. 11 is a diagram for explaining the meshing state between the first cutting blade roll and the second cutting blade roll in another embodiment. As shown in FIG. 11, the first cutting blade roll 210a has a first narrow-width portion 219a, a first wide-width portion 218a, and a first medium-width portion 217a whose width is intermediate between the first narrow-width portion 219a and the first wide-width portion 218a. Further, the first cutting blade roll 210a has a second narrow-width portion 229a, a second wide-width portion 228a, and a second medium-width portion 227a whose width is intermediate between the second narrow-width portion 229a and the second wide-width portion 228a.

[0104] Further, the second cutting blade roll 230a has a third narrow portion 339a, a third wide portion 338a, and a third middle 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 middle portion 347a whose width is intermediate between the fourth narrow portion 349a and the fourth wide portion 348a.

[0105] Also, in this embodiment, the number of scraping positions for each cutting blade roll is two for each, but it is not limited to this, and it may be three or more. In this case, the number of each scraping portion in each shaving body is three or more.

[0106] Also, in this embodiment, the shaving for scraping the fresh noodle strand is of an integrated type in which the first shaving portion and the second shaving portion are integrated, but it is not limited to this. For example, as shown in FIG. 12, the first shaving portion and the second shaving portion may be of an independent type. FIG. 12 is a front view for explaining the structure of a noodle cutting device for noodle making in another embodiment.

[0107] For example, as shown in FIG. 12, a noodle cutting device 200A for noodle making according to another embodiment has a first shaving portion 250A arranged opposite to the first cutting blade roll 212a and a second shaving portion 250B independent of the first shaving portion 250A. The noodle cutting device 200A for noodle making also has a third shaving portion 260A arranged opposite to the second cutting blade roll 232a and a fourth shaving portion 260B independent of the third shaving portion 260A.

[0108] The tip of the scraping tooth (scraping position) of the first shaving portion 250A is arranged at a position of 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). Also, the tip of the scraping tooth (scraping position) of the second shaving portion 250B is arranged at a position of 120° to 210°, particularly preferably 150° to 180° from the meshing position K in the first rotation direction R1 around the first rotation axis C1 (12a) (β). Further, the tip of the scraping teeth (scraping position) in the first scraping portion 250A and the tip of the scraping teeth (scraping position) in the second scraping portion 250B are preferably arranged to be separated from each other by 90° or more in the first rotation direction R1 about the first rotation axis C1. As a result, the raw noodle strands 3 scraped out at each scraping position are scraped out with significantly different behaviors from each other, and it is suppressed that they overlap linearly or in a planar shape.

[0109] Also, in the present embodiment, in each fitting portion group, the narrow-width portion and the wide-width portion are arranged so as to continuously repeat a plurality of sets of a predetermined arrangement pattern in each rotation axis direction. For example, they are arranged so as to continuously repeat a plurality of sets of an arrangement pattern of a narrow-width portion, a narrow-width portion, and a wide-width portion. In the present embodiment, the narrow-width portions are arranged continuously, but when they are arranged so that the narrow-width portions are not continuous, binding and the like are more suppressed. In the noodle-making cutting device, in each of the groups of a plurality of first fitting portions and the groups of a plurality of fourth fitting portions, each narrow-width portion is arranged so as not to be continuous in each rotation axis direction, and each wide-width portion is arranged so as not to be continuous in each rotation axis direction, which is preferable from the viewpoint of suppressing binding and the like. Here, when there are two types of fitting portions with different widths, there is only an alternating arrangement pattern, and it may not be optimal from the product surface in relation to the required texture and the like. When there are three or more types of fitting portions with different widths, the arrangement patterns also increase, and it is possible to select a preferable aspect from both sides of binding properties and the like and texture and the like.
