Description

  The present invention relates to an apparatus for reducing the diameter of a noodle string, which narrows noodle strings such as raw noodles, udon and soba so as to have a predetermined shape and cross-sectional area.

  Traditionally, noodles such as raw noodles, udon, and soba are produced by kneading while adding water to the main raw material to form a lump noodle dough, and forming the noodle dough into noodle strings of a predetermined thickness. For example, in the case of raw noodles, first, knead uniformly with a kneader while adding a small amount of salt and water to the flour as the main raw material. A lump dough is made by this kneading operation (Ode operation), and the noodle dough is aged for several hours. This aged noodle dough is pressed and extended by a spreader, and then cut into a predetermined width to form a rod shape. And what was formed in this rod shape is rolled with an Itagi machine, and the rolled thing is wound up in a storage tank in the shape of a spiral. In this state, the noodle strings wound in the storage tank are formed into a round bar shape having a diameter of about 40 to 50 mm, for example. Then, in this state, it is aged for several hours, and the gluten structure of the flour is strengthened to increase the elasticity and viscosity.

  And the comparatively thick noodle string wound in this storage tank is shape | molded into a thin string-like noodle string by twisting with a noodle string winding machine. The noodle strings are reduced in diameter by a device for reducing the diameter of the noodle strings provided in the noodle string winding machine. The diameter of the noodle strings is reduced by, for example, two stages or three stages, and the noodle strings can be formed into a predetermined diameter of, for example, about 20 to 6 mm. And this noodle string thinned is wound in a storage tank in the shape of a spiral (for example, refer to patent documents 1).

  In the middle of the diameter reduction performed stepwise, a predetermined aging time is secured and aging is also performed. Further, during the diameter reduction operation, the noodle strings are twisted, and this twist also strengthens the gluten structure, and the noodle strings are tightened more precisely.

When reducing the diameter of the noodle strings using the apparatus for reducing the diameter of the noodle strings, for example, as shown in FIG. It is conceivable that the pair of upper and lower processing rolls 60 and 61 are set so that the shape of the opening 62 formed between the pair of upper and lower processing rolls 60 and 61 is circular.
No. 7-18298

  However, as shown in FIG. 9 (b), even if the shape of the mouth portion 62 is set to be circular, the noodle string n after molding may bulge up and down depending on the properties of the noodle string n. It may become a vertically long, oval shape.

  Therefore, as shown in FIG. 9 (c), the noodle string n after molding is bulged in the vertical direction to become a vertically long substantially oval shape. It is conceivable to set the mounting positions of the upper and lower processing rolls 60 and 61 so as to be flat only.

  However, the cross-sectional shape of the processing grooves 60a and 61a formed on the outer periphery of the conventional pair of upper and lower processing rolls 60 and 61 shown in FIGS. 9A, 9B, and 9C is semicircular. The cross-sectional shape of the noodle strings n after the diameter reduction shown in FIG. 9C does not become a circle, and the upper surface portion and the lower surface portion become a substantially rectangular shape having a roundness.

  In addition, as shown in FIGS. 9B and 9C, the noodle strings n after forming are swelled in the vertical direction to have a vertically long substantially oval shape or the like. The noodle strings n are a pair of processing rolls 60, After passing through the opening 62 between 61, the pressing force of the upper and lower processing rolls 60, 61 is released, and at this time, it bulges in the vertical direction by the restoring force present in the noodle strings n. is there.

  The properties that cause a restoring force to the noodle strings n after the diameter reduction are, for example, the length of the aging time before the diameter reduction work or during the diameter reduction work, the temperature and humidity during the work, etc. Every n is different. Furthermore, the property that causes the restoring force to be generated in the noodle strings n varies depending on the noodle strings n depending on conditions such as the main component of the noodle strings n, the water content, the thickness before the diameter reduction. For example, when ripening progresses or when the temperature is high or humidity is high, the noodle string n becomes soft and the restoring force is small, and when aging is delayed or the temperature is low or humidity is low, the noodle string n is It becomes hard and has great restoring force.

  Furthermore, also in the noodle strings n accommodated in the accommodating tank, the restoring force is different between the portion near the bottom of the accommodating tank and the upper portion away from the bottom. Because, for example, if noodle strings n are passed through the processing roll twice, the portion near the bottom of the storage tank of the noodle strings n passed through the processing roll for the first time until the processing roll is passed for the second time The time is relatively longer than the time until the upper part of the noodle strings n passed through the processing roll first from the bottom of the storage tank is passed through the processing roll for the second time. This is because the ripening degree of the noodle strings n is different. Thereby, also in the noodle strings n accommodated in the same accommodating tank, the restoring force of the noodle strings n is different in the upper part, the middle part and the lower part of the accommodating tank.

  Therefore, when passing the noodle strings n through the apparatus for reducing the diameter, for each storage tank in which the noodle strings n are stored, and among the noodle strings n stored in the same storage tank, the upper portion of the storage tank, It is necessary to adjust the interval between the pair of machining grooves 60a and 61a to an appropriate interval according to the intermediate portion and the lower portion, and it is desired to be able to make the adjustment easily and accurately.

  The present invention has been made to solve the above-described problems, and it is possible to easily and accurately adjust the interval between the processing grooves formed in the paired processing rolls to an appropriate interval. An object of the present invention is to provide a device for reducing the diameter of noodle strings.

  According to the apparatus for reducing the diameter of noodle strings according to the present invention, the noodle strings are formed in a predetermined cross-sectional shape and thickness by passing the noodle strings between a pair of opposed processing grooves of a pair of processing rolls. Can do. And the space | interval of a pair of process groove | channel can be adjusted by operating or operating a groove | channel space | interval adjustment mechanism. Thereby, the noodle strings can be formed in a desired cross-sectional shape and thickness at a desired timing. Moreover, since both are mutually connected via a power transmission mechanism so that each peripheral speed of a pair of processing rolls may become substantially the same, without causing a slip between each processing roll and noodle strings. The noodle strings can be thinned. Therefore, the surface of the noodle strings can be formed smoothly and with a uniform thickness.

  And in the apparatus for reducing the diameter of the noodle strings according to the present invention, the groove interval adjusting mechanism includes a bearing portion that rotatably supports one of the paired processing rolls, and the bearing. It is good to provide the guide part which guides a part to the direction which approaches a part with respect to the other process roll, and the direction which leaves | separates, and the feed mechanism part which moves the said bearing part along the said guide part. According to this groove interval adjusting mechanism, the bearing portion can be moved along the guide portion by operating or operating the feed mechanism portion.

It is good to provide the latching | locking part for stopping the movement of the said bearing part urged | biased in a predetermined position.

  According to this feed mechanism portion, for example, when the feed screw portion is rotated in one direction, the swinging portion swings in a direction away from the frame body, whereby the locking portion provided in the swinging portion is Move away from the bearing. At this time, since the bearing portion is urged by the urging means in the direction toward the locking portion, the bearing portion moves in the same direction following the locking portion. In this way, for example, one processing roll can be moved in a direction to separate it from the other processing roll. Then, contrary to the above, when the feed screw portion is rotated in the other direction, an operation opposite to the above is performed, and one processing roll is resisted against the urging force of the urging means, and the other processing roll is applied to the other processing roll. It can be moved in the approaching direction. In this way, the pair of processed grooves can be enlarged / reduced to have a desired interval.

It is good to do. In this way, when the cross-sectional shape of each machining groove that is paired is a semi-elliptical shape or a substantially semi-elliptical shape that is formed by cutting the ellipse along the long axis, the noodle strings are paired with this. By passing between the processed grooves, the noodle strings can be formed so that the cross section thereof is elliptical or substantially elliptical. When the noodle strings are formed in this way, when the noodle strings bulge in the minor axis direction of the ellipse due to the restoring force present in the noodle strings, the cross-section of the noodle strings becomes circular or nearly circular be able to. As a result, the appearance and texture of the noodle strings can be improved.

  According to the apparatus for reducing the diameter of the noodle strings according to the present invention, the gap between the paired machining grooves can be adjusted by operating or operating the groove interval adjusting mechanism. For each of the storage tanks stored, and among the noodle strings stored in the same storage tank, according to the upper part, the middle part and the lower part of the storage tank, the interval between the paired processing grooves is set. Therefore, it is possible to adjust to an appropriate interval easily and accurately at a desired timing. Thereby, for example, the thickness and density can be made uniform over the entire length of the noodle strings, and as a result, the texture and appearance of the noodles made with the noodle strings can be improved.

Then, the noodle strings n having a reduced diameter can be automatically wound in a multistage manner in the downstream storage tank 12.

  Next, after the aging time of about 1 hour has passed, for example, the noodle strings n thinned by using the first processing rolls 27 and 28 are each subjected to the rolls 3 and 4 and a pair of upper and lower portions in the same manner as described above. The second processing rolls 29 and 30 and the guide rod 11 are hung or passed. And by driving the drive unit 19, the noodle strings n that have been reduced in diameter by the first processing rolls 27 and 28 in the upstream storage tank 12 are twisted and the diameter reduction device 9 The pair of second processing rolls 29 and 30 can reduce the diameter of the noodle strings n to a predetermined thickness. Then, the noodle strings n having a reduced diameter can be automatically wound in a multistage manner in the downstream storage tank 12. The noodle strings n thus formed and reduced in diameter are further processed and processed to produce, for example, raw noodles.

  Next, the operation of the noodle string thinning device 9 will be described with reference to FIGS. According to the noodle string thinning device 9, as shown in FIGS. 6 and 7, the upper and lower pair of first processing rolls (or the upper and lower pair of second processing rolls 29 and 30) 27 and 28 are opposed to each other. By passing the noodle strings n through the openings 44, 44 between the pair of processed grooves (27a, 28a), (29a, 30a), the noodle strings n can be formed into a predetermined cross-sectional shape and thickness. .

  And according to the groove | interval space | interval adjustment mechanism 38 shown in FIG. 4, when an operator operates the feed screw part 54, a pair of process groove 27a formed in a pair of upper and lower process rolls 27, 28, ... 28a,... Can be adjusted, whereby the noodle strings n can be formed in a desired cross-sectional shape and thickness at a desired timing.

  Further, according to the groove interval adjusting mechanism 38 shown in FIG. 4, when the operator operates the feed screw portion 54, the bearing portions 40, 40 to which the upper first and second processing rolls 27, 29 are attached are provided. It is the structure which can be moved only the desired distance to the up-down direction along the guide parts 50 and .... Thereby, the distance between the pair of upper and lower first and second processing rolls 27, 28,..., That is, the vertical distance between each pair of processing grooves 27a, 28a,. Moreover, it can be narrowed or expanded accurately.

  Further, as shown in FIG. 5, the upper and lower pairs of first processing rolls (and the upper and lower pair of second processing rolls 29 and 30) 27 and 28 have their upper and lower respective processings so that their peripheral speeds are substantially the same. Since the rolls 27, 28,... Are connected to each other via the upper and lower spur gears 37a, 37b of the power transmission mechanism 37, the upper and lower processing rolls 27, 28,. The noodle strings n can be reduced in diameter without causing any slippage between them. Therefore, the surface of the noodle strings n can be formed smoothly and with a uniform thickness.

  Next, with reference to FIG. 8, the distance between the pair of upper and lower second processing rolls (and first processing rolls 27 and 28) 29 and 30, that is, each pair of processing grooves (29a and 30a) and (27a and 28a). A procedure for adjusting the interval will be described. FIG. 8 shows a procedure for reducing the diameter of the noodle strings n that have been reduced in diameter through, for example, the first processing rolls 27 and 28 through the second processing rolls 29 and 30 after a predetermined aging time has elapsed. ing.

  In the storage tank 12 shown in FIG. 8, noodle strings n that have been reduced in diameter through the first processing rolls 27 and 28 are spirally wound in order from the bottom of the storage tank 12 and stacked in a plurality of stages. Yes. Accordingly, the noodle strings n accommodated in the accommodating tank 12 are processed in the order of the lower part C, the intermediate part B, and the upper part A in order from the time when the diameter is reduced by the first processing rolls 27 and 28. It is getting longer. The elapsed time of the lower part C is the longest.

  Moreover, since the order in which the noodle strings n are subsequently reduced by the second processing rolls 29 and 30 is the order of the upper part A, the intermediate part B, and the lower part C, the noodles stored in the storage tank 12 The time required for the line n to be reduced in diameter by the second processing rolls 29 and 30 becomes longer in the order of the lower part C, the intermediate part B, and the upper part A. Also in this case, the time of the lower part C becomes the longest.

  Therefore, the time required for the noodle strings n that have been reduced in diameter by the first processing rolls 27 and 28 and accommodated in the storage tank 12 to be reduced in diameter by the second processing rolls 29 and 30 is lower. C, the middle part B, and the upper part A become longer in this order, and therefore the aging time of the lower part C of the noodle strings n is the longest.

  As a result, as shown in FIG. 8, the cross-sectional area of the noodle strings n just before passing through the second processing rolls 29 and 30 is relatively large in the upper part A, medium in the middle part B, and small in the lower part C. It has become. The reason why the cross-sectional areas are different is that the aging time is short in this order. The upper part A has a short aging time and a large cross-sectional shape close to the shape of the opening 44 of the first processing rolls 27 and 28. And as the aging time is longer, the aging degree is higher and the noodle strings n become thinner. The lower part C has the longest aging time and has a small cross-sectional shape that is substantially circular.

  Further, the vertical distance (the shape of the opening 44) of the processing grooves 27a and 28a of the pair of upper and lower first processing rolls 27 and 28 is such that the noodle strings n that have been reduced in diameter by the first processing rolls 27 and 28 are aged. In such a state, for example, the cross-sectional shape of the noodle strings n is set to be circular. That is, the opening 44 of the first processing rolls 27 and 28 is set to have a substantially elliptical shape that is long horizontally.

  The upper and lower intervals (shape of the opening portion 44) of the processing grooves 27a and 28a are set so that the shape after ripening becomes a circle in this way, and the diameter is reduced by the first processing rolls 27 and 28. This is because when the noodle strings n are reduced in diameter by the second processing rolls 29 and 30 and the noodle strings n are aged, the cross-sectional shape is surely circular.

  Next, as shown in FIG. 8, when the noodle strings n in the upper part A are passed through the second processing rolls 29, 30 among the noodle strings n stored in the storage tank 12, the upper and lower processing grooves 29a, 30a are used. Is set to a1 which is relatively narrow. When passing the noodle strings n of the intermediate part B through the second processing rolls 29, 30, the interval between the upper and lower processing grooves 29a, 30a is set to a medium a2, and the noodle strings n of the lower part C are set to the second processing rolls 29. , 30, the distance between the upper and lower machining grooves 29a, 30a is set to a relatively large a3. When the noodle strings n that have been reduced in diameter by the second processing rolls 29 and 30 in this way are aged, as shown in FIG.

  As described above, according to the upper part A, the middle part B, and the lower part C of the noodle strings n accommodated in the accommodating tank 12, the interval between the upper and lower processed grooves 29a, 30a is changed to the upper part with a low aging degree. The noodle strings n in the lower part C having a high degree of maturation are large in the extent that the noodle strings n of A bulge in the vertical direction by the restoring force in the vertical direction after passing through the second machining rolls 29 and 30. This is because the degree of bulging in the vertical direction by the restoring force in the vertical direction after passing through 29 and 30 is small.

  Therefore, according to the upper part A, the middle part B, and the lower part C of the noodle strings n accommodated in the same accommodating tank 12 so that the cross-section of the noodle strings n after aging becomes a circle having substantially the same size. When the respective parts pass through the second processing rolls 29 and 30, the intervals between the upper and lower processing grooves 29a and 30a are changed.

  In addition, in FIG. 8, among the noodle strings n accommodated in the same accommodating tank 12, it is necessary to change the interval between the upper and lower processing grooves 29a and 30a according to the upper part A, the intermediate part B, and the lower part C. As described above, since the maturity and properties of the noodle strings n are different for each storage tank 12 in which the noodle strings n are stored, the noodle strings n are also formed in the second processing roll 29 for each storage tank 12. , 30 and when passing through the first processing rolls 27, 28, it is necessary to adjust the interval between the upper and lower processing grooves (29a, 30a), (27a, 28a).

  Therefore, according to the noodle string thinning device 9 of the present invention, as shown in FIG. 4 and the like, the operator operates the feed screw portion 54 to allow the interval between the upper and lower machining grooves 27a, 28a,. Can be adjusted easily and accurately at a predetermined timing. Thereby, for example, the thickness and density can be made uniform over the entire length of the noodle strings n, and as a result, the texture and appearance of the noodles made with the noodle strings n can be improved.

  Further, as shown in FIG. 8 and the like, the cross-sectional shape of each pair of processed grooves 27a, 28a,... Is a semi-elliptical shape (or substantially semi-circular shape) formed by cutting an elliptical shape along the major axis. So that the cross-section of the noodle strings n becomes elliptical (or substantially elliptical) by passing the noodle strings n between the pair of processed grooves 27a, 28a,... can do. When the noodle strings n are formed in this way, when the noodle strings n bulge in the minor axis direction of the ellipse due to the restoring force existing in the noodle strings n, the cross section of the noodle strings n is circular or nearly circular Can be. Thereby, the appearance, texture, etc. of the noodle strings n can be improved.

  However, the noodle string thinning device 9 of the above embodiment is configured to include two sets of first and second processing rolls (27, 28), (29, 30) as shown in FIG. Instead of this, a configuration including one set or three or more sets of processing rolls may be employed.

  In the noodle string thinning device 9 of the above embodiment, the noodles are described as an example. However, the noodle strings n such as udon other than the noodles, the buckwheat noodles, and the like can be thinned. Can do.

  In addition, as shown in FIG. 4, the groove interval adjusting mechanism 38 of the above embodiment is configured such that the operator manually operates the feed screw portion 54, but instead of this, the operation is performed using an electric motor, for example. You may make it do.

  Moreover, although the power transmission mechanism of the said embodiment was set as the structure which connects an upper side axis | shaft and a lower side axis | shaft with an up-and-down spur gear, as shown in FIG. 5, it is good also as structures other than this. For example, the upper shaft and the lower shaft may be coupled to each other via a flexible cable that can transmit a rotational force.

  Furthermore, although the processing groove of the said embodiment was made into the semi-elliptical shape as shown in FIG. 6, it is good also as shapes other than this. For example, when the cross-sectional shape of the noodle strings is rectangular or oval, it can be a shape corresponding to the cross-sectional shape.

  As described above, the apparatus for reducing the diameter of the noodle strings according to the present invention makes it possible to easily and accurately set the interval between the processing grooves formed on each pair of processing rolls at a desired timing. It is suitable for application to such a device for reducing the diameter of noodle strings.
