JP6217973B2 - Mixed cutting blade for noodles and its shredding method - Google Patents

Description

  The present invention relates to a cutting blade for forming a noodle band from a dough that has been added to a raw material and kneaded in a noodle manufacturing process, and then chopping the noodle band adjusted in thickness into a large number of noodle strings at the same time.

  Conventionally, cutting blades for square noodles and round noodles have been used to chop a noodle strip adjusted to a predetermined thickness into noodle strings. Since the noodle strings cut with a single groove width of these cutting blades have a uniform cross section and no handmade feeling, use a mixed count cutting blade (for example, FIG. 13) mixed with different groove widths, Mixing noodle strings with different thicknesses in a single ball gives a change to make it feel handmade.

  However, the noodle strings by the cutting blade of the mixed count are different in the width of the noodle strings, but the cross-section of the noodle strings is limited to a rectangle (for example, FIG. 14) if it is for square noodles, and is oval if it is for round noodles. Due to the limited shape and poor change in cross-sectional shape, there was a big gap from hand-made noodles and hand-rolled noodles.

  The inventors of the present application have disclosed Patent Document 1 as one of the cutting blades that can change the shape of the cross section of the noodle strings. In this cutting blade, the blade edge of each blade portion of each rotating roller is formed on one annular inclined surface inclined with respect to the axis of the rotation shaft of the rotating roller, and the inclined surfaces of each blade edge are opposed to each other. The noodle strip was deformed in a diamond shape when the noodle strip was chopped into groove widths, and it was possible to cut the noodle strip into an unprecedented handmade noodle strip.

  Moreover, there is Patent Document 2 as a cutting blade that cuts a cross section of a noodle string into a diamond shape. However, according to Patent Document 2, since the step of the abdomen is formed at an obtuse angle by the cutting by sliding contact between the cutting edge of the blade and the step of the abdomen, there is a problem that it is difficult to sharply cut.

JP-A-8-38027 JP-A-10-262539

  For the purpose of further enhancing the handmade feeling of noodles obtained with the cutting blade of Patent Document 1, when a mixed count cutting blade is configured, the noodle wire obtained from the wide groove is poor in rhombus-like deformation and the narrow groove The noodle strings obtained from No. 1 are excessively rhombus-like deformed, and it is difficult to obtain desirable rhombus-like deformation aimed at all grooves having different widths.

  The present invention solves such a problem, and it is a cutting blade of a type in which the cross section of the noodle strings is deformed in a rhombus shape at the same time as chopping, and is optimal for any groove width when mixed counts with different groove widths are used. The object is to provide a cutting blade from which noodle strings having a rhombus-like cross section can be obtained.

  In order to solve the above-mentioned problems, the cutting blade of Patent Document 1 was searched for conditions for obtaining an optimal rhombus-like deformation with a wide groove and a narrow groove. On the other hand, in a count with a narrow groove, by inserting a thin noodle band, it was possible to adjust to a rhombus-like cross section suitable for each groove width. However, in order to change the thickness of the noodle strip to be inserted, it is necessary to perform rolling before chopping with an uneven roller according to the groove width, which is unreasonable in that the apparatus is not limited to a cutting blade and requires a large apparatus.

  Again, the cutting blade of Patent Document 1 was examined without changing the thickness of the noodle strip. The process of chopping a noodle strip with a rhombus-like cross section aiming at the noodle band can be divided into a process 1 for cutting into a groove width and a process 2 for deforming into a rhombus. At the level at which the blade portions are pushed into contact with each other in the process 1, the resilience of the noodles trying to return from the rhombus to the rectangle works greatly, and the rhombus-like deformation of the cross-section of the noodle strings is almost canceled. Therefore, in the process 2, it was necessary to push it past the level where the blade portions contact each other, and to deform it more greatly than the rhombus aiming at the noodle strings by the opposed inclined surfaces of the blade portions.

  However, if the thickness of the noodle strips to be inserted is the same, the larger the groove width, the farther the inclined surface facing the blade portion is, and the ratio of the area where the inclined surface of the blade portion contacts the periphery of the noodle wire is reduced. It was found that the cross section was difficult to deform like a rhombus.

  In addition, when the thickness of the noodle strip to be inserted is thin relative to the groove width of the cutting blade roller, when the noodle strip is pressed to the deep level in the opposite direction, the noodle strip slides in the groove and changes its direction. It turned out that it becomes difficult to deform.

  That is, the problem solving means 1 is a cutting blade in which a pair of cutting blade rollers rotate in a direction to sandwich the noodle band, and the cutting blade roller has a large number of annular blade portions and grooves in the rotation axis direction. Is formed of a surface that is inclined with respect to the rotation axis and a surface that is perpendicular to the rotation axis, and the inclined surfaces of one cutting blade roller are in the same direction, and the inclined surfaces are made to face each other by sliding and engaging the vertical surfaces from the respective blade edges, It is a mixed count composed of different groove widths, and is characterized in that the outer peripheral diameter of the blade portion of the inclined surface facing with a large groove width is larger than the outer peripheral diameter of the blade portion of the inclined surface facing with a small groove width. Therefore, the side surface of the cutting blade roller is uneven in the rotational axis direction.

  According to the means 1 for solving the problem, when the large groove width is compared with the small groove width, the opposed inclined blades are deeply engaged with each other, so that the cut faces of the noodle strings are pushed into a deep level in the opposite direction. This has the effect of preventing a reduction in the ratio of contact of the inclined surface around the cross section of the noodle strings. As a result, even in the case of a groove having a large width, a rhombus-like cross section deformed to a preferable degree can be obtained after restoration to return from a rhombus to a rectangle.

  Problem solving means 2 is characterized in that, in addition to problem solving means 1, the interval between the inclined surfaces facing each other with a large groove width is smaller than the interval between the inclined surfaces facing each other with a small groove width.

  According to the means 2 for solving the problem, by reducing the interval between the inclined surfaces facing each other with a large groove width, the deformed noodle strings are pressed by the opposing inclined surfaces, and the diagonal forming the obtuse angle of the rhombus cross section is flat. Due to the extended action, it is possible to eliminate the resilience itself of returning to the rectangle from the diamond shape. At the same time, the width of the cut noodles can be increased to obtain a difference in thickness more than the difference in groove width.

  The means 3 for solving the problem is a method using the cutting blade according to any one of claims 1 and 2, and is limited to a noodle strip having a thickness of 80 to 140%, preferably 90 to 120% of the average groove width. The actions of the means 1 and 2 can be further enhanced.

  According to the mixed cutting blade of the present invention, an optimal rhombus-like deformation is given to the noodle strings for each groove width of the cutting blade roll, and by making the difference in width more conspicuous than the conventional mixed count cutting blade, The noodles can be made to have a rhombus-like cross section that is optimally deformed for each thickness, and the noodle strings can have a variety of thicknesses.

  With such a variety of noodle strings, it is possible to impart an unprecedented handmade feeling to the noodles, improve the taste and increase the commercial value of the noodle products.

(Example of the present invention)
The features of the present invention will be illustrated below with reference to FIGS. 1 to 8, but are not limited to these examples.

  1 to 3 show the outer shape of the cutting blade of the present invention. A rotary shaft 1a (axis line is 1al) and a rotary shaft 2a (axis line is 2al) of the cutting blade rollers 1 and 2 are supported in parallel by frames 3 and 4. The rotation shaft 1a of the cutting blade roller 1 receives rotational driving at 1c and transmits it to the cutting blade roller 2 through gears 1b and 2b, and rotates the cutting blade rollers 1 and 2 in the opposing direction of 1r and 2r, respectively. The stays 5a and 5b connect the frames 3 and 4 in parallel to prevent twisting of the cutting blade roller and at the same time serve as attachment seats for the scrapers 6a and 6b (plan view omitted). The adjusting screws 3a and 4a finely adjust the distance between the cutting blade rollers 1 and 2.

  As described above, the arrangement and position adjustment of the cutting blade roller, the structure for transmitting the power, etc. are not different from the conventional general cutting blade.

  FIG. 4 shows an enlarged part of the outer shape of the cutting blade roller 1, and FIG. 5 shows a cross section of the position where the cutting blade roller 1 engages with the cutting blade roller 2 most deeply.

Three kinds of groove widths are mixed in the cutting blade rollers 1 and 2, and the groove ratio of 2.5 mm: 2.2 mm: 1.9 mm = 6: 6: 5, and the groove width of 2.5 mm is 11a and 12a, The groove width of 2.2 mm is 11b and 12b, and the groove width of 1.9 mm is arranged in a section of 11c and 12c. In addition, the groove width of this invention refers to the space | interval of the blade edge | tip of an adjacent blade part, and an average groove width will be 2.22 mm.

  The blade portion of the inclined surface facing, for example, 11at, in the section having a groove width of 2.5 mm, is formed by a surface 11as perpendicular to the rotation axis and an inclined surface 11au that faces all rightward, and is continuously provided via the bottom portion 11d. The outer peripheral diameter of these blade portions 11at is 40 mm. Similarly, the inclined blades, for example 11bt, facing each other in the section having a groove width of 2.2 mm are formed of a surface 11bs perpendicular to the rotation axis and an inclined surface 11bu all rightward, and are connected via the bottom 11d. These blade portions 11bt have an outer peripheral diameter of 39.2 mm, and the inclined blade portions, for example, 11ct, which face each other in the section having a groove width of 1.9 mm, are all inclined rightward with respect to the surface 11cs perpendicular to the rotation axis. It is formed with the surface 11cu and is continuously provided through the bottom part 11d, and the outer peripheral diameter of these blade parts 11ct is 38.4 mm. In addition, the blade edge | tip of this invention points out the outer periphery end of the blade part formed in an acute angle by the perpendicular surface and sloping surface which are in sliding contact.

  Since the cutting blade roller 1 includes outer peripheral diameters of 40 mm, 39.2 mm, and 38.4 mm, the side surface has irregularities in the rotational axis direction, and the cutting blade roller 2 similarly has an outer peripheral diameter of 40 mm, 39.2 mm, 38. Since it includes 4 mm, the side surface of the cutting edge roller is uneven in the rotational axis direction.

  FIG. 6 shows an AA cross section in which the blade portion 11at and the blade portion 12at are in sliding contact, a BB cross section in which the blade portion 11bt and the blade portion 12bt are in sliding contact, and a CC cross section in which the blade portion 11ct and the blade portion 12ct are in sliding contact. showed that.

  The maximum width 12ato of the overlap (sliding contact portion) of the blade portions 11at and 12at having a groove width of 2.5mm is 2.2mm, and the maximum width 12bt of the overlap of the blade portions 11bt and 12bt having a groove width of 2.2mm is 1.4mm. The maximum width 12 cto of the overlap between the blade portions 11 ct and 12 ct having a width of 1.9 mm is 0.6 mm, and the groove width 2.5 mm is deepest.

  Next, FIG. 7 shows a cross-section in a state where the noodle strip of udon having a thickness of 2.2 mm is shredded at the deepest engaging position (FIG. 5), and FIG. 8 is extracted from FIG. The noodle strip cross section and the noodle strip cross section after being cut out are shown side by side. The noodle band thickness of 2.2 mm corresponds to 99% of the average groove width of the cutting blade roller.

  The noodle strip section extracted from FIG. 7 is the shape 14a, 14b, 14c of the moment when the noodle strip is cut into the respective groove widths of the cutting blade roller and then deformed to a diamond shape at the maximum, and has both plasticity and elasticity. The noodle strings were cut out after a certain restoration in response to the temporary deformation, and ideal rhombus-like cross sections 15a, 15b and 15c were obtained from the respective groove widths.

  At that time, the interval between the inclined surfaces facing each other is 1.2 mm for 13a with a groove width of 2.5 mm, 1.4 mm for both 13b and 13c, and the noodle strings with a groove width of 2.5 mm are pressed by the opposing inclined surfaces, It was cut into a 15a noodle strip. This cross section 15a approximated 14a, and the cut noodle string width 16a was larger than the difference in groove width compared to 16b and 16c.

(Comparative example of the present invention)
Next, comparative examples of flat cutting blades whose side surfaces are not uneven in the direction of the rotation axis are shown in FIGS. 9 to 11, and a cross section of the noodle strings cut out by the cutting blades is shown in FIG. The arrangement and position adjustment of the cutting edge roller and the structure for transmitting power are the same as those of the embodiment of the present invention shown in FIGS.

  FIG. 9 shows an enlarged part of the outer shape of the cutting blade roller 3, and FIG. 10 shows a cross section of the position where the cutting blade roller 3 engages with the cutting blade roller 4 most deeply.

  Three types of groove widths of 2.5 mm, 2.2 mm, and 1.9 mm are mixed in the cutting blade rollers 3 and 4, the groove width of 2.5 mm is 23a and 24a, the groove width of 2.2 mm is 23b, The groove widths of 24b and 1.9 mm are collectively arranged in the sections 23c and 34c.

  In the section having a groove width of 2.5 mm, for example, the blade portion 23at is formed by a surface 23as perpendicular to the rotation axis and a surface 23au that is inclined rightward, and is continuously provided via a bottom portion 23d. Similarly, in a section having a groove width of 2.2 mm, for example, the blade portion 23bt is formed by a surface 23bs perpendicular to the rotation axis and a surface 23bu that is inclined rightward, and is continuously provided via a bottom portion 23d. Even in the section of 23c having a width of 1.9 mm, the blade portion 23ct is formed by a surface 23cs perpendicular to the rotation axis and a surface 23cu that is inclined rightward, and is continuously provided via the bottom 23d. The above points are the same as those of the cutting blade rollers 1 and 2.

  The cutting rollers 3 and 4 have the blades 23at, 23bt, 23ct, 24at, 24bt, and 24ct all having an outer diameter of 39.2mm, and the maximum overlapping width of the blades is 1.4mm. The side surfaces of the rollers 3 and 4 are different from the cutting blade rollers 1 and 2 in that the side surfaces of the rollers 3 and 4 are flat in the rotation axis direction and are not flat.

  FIG. 11 shows a cross section where the same noodle strip as in the embodiment of the present invention is shredded at the deepest meshing position (FIG. 10), and FIG. 12 shows a cross section of the noodle strip extracted from FIG. The cross-sections of the noodle strings are shown side by side.

  The noodle strip section extracted from FIG. 12 is the shape 26a, 26b, 26c of the instant when the noodle strip is shredded to the respective groove widths of the cutting blade rollers and then deformed to a diamond shape at the maximum. The noodle strings possessed together were cut out after a certain restoration by repulsion against this temporary deformation, and the noodle strings of the cross section 27a lacked rhombus-like deformation, whereas the noodle strings of the cross section 27c had excessively rhombus-like deformation.

  The intervals between the inclined surfaces facing each other were 1.6 mm for 25a having a groove width of 2.5 mm, 1.3 mm for 25b having a groove width of 2.2 mm, and 1.1 mm for 25c having a groove width of 1.9 mm. Since the noodle strings having a groove width of 2.5 mm were insufficiently deformed in the state of 26a, the shape of the noodle strings 27a was not sufficiently deformed. On the other hand, the noodle strings having a groove width of 1.9 mm were pressed by the opposing slopes, and the restoration was slight, and the wide section 27c was cut out instead of the narrow groove width. As a result, the noodles were not greatly different in the noodle line widths 28a, 28b and 28c.

(Summary of Examples)
According to the present invention in which the outer peripheral diameter of the blade portion is differentiated according to the groove width, a noodle string having a rhombus-like cross section is optimally obtained for each different groove width as compared with the comparative example having no difference in the outer peripheral diameter, and the thickness. Also got sharpness. Then, when the same number of these noodle strings were mixed and boiled, the texture was different and the handmade feeling that was not found in the past was obtained.
