Description

Coarse noodle strip forming roll device

The present invention relates to a noodle making machine for producing noodles such as udon, ramen, soba and pasta. In particular, the present invention relates to a rough noodle strip forming roll device that forms a large number of small pieces of dough into a continuous rough noodle strip.

In general, in a noodle making machine, a continuous noodle strip is formed into a noodle strip having a desired thickness and width by a number of rolling rolls. Noodle strings are formed by cutting the noodle strip in the longitudinal direction. Such a noodle making machine mainly includes a kneading mixer, a rough noodle strip forming roll device, a plurality of rolling roll devices, a noodle strip cutting machine, and a noodle strip cutting machine. In a kneading mixer, flour such as wheat flour or buckwheat flour is kneaded while salt water is added to the flour. When buckwheat is produced, the wheat flour is evenly mixed with the buckwheat flour as a “tie”. Numerous spherical pieces of dough (hereinafter “dough grains”) grow in a kneading mixer. A large number of dough grains are sent to a coarse noodle strip forming roll device.

The coarse noodle strip forming roll apparatus has a pair of rolls, and a gap (hereinafter referred to as “roll gap”) is formed between the pair of rolls. The coarse noodle strip forming roll device collects the dough grains in the roll gap and presses and solidifies the dough grains to form a dough lump. The coarse noodle strip forming roll device rolls a lump of dough to form a continuous coarse noodle strip having a thickness of about 7 mm to 15 mm. The rough noodle strip is thinned in stages by a plurality of rolling roll devices, and a noodle strip having a required thickness and width is formed. The noodle strip cutting machine generates a noodle strip having a desired thickness by cutting the noodle strip vertically with a pair of cutting blade rolls. The noodle string cutting machine cuts a continuous noodle string into a predetermined length by a cutter.

Since the surface of the dough is smooth and highly elastic, a rolling roll with a smooth surface cannot sufficiently hold the dough. Therefore, such a rolling roll may not be able to feed out the dough. Patent document 1 is disclosing the rolling roll which has the outer peripheral surface formed in the unevenness | corrugation. Since the surface layer of the dough containing moisture is highly sticky, a part of the dough may stick to the roll. When time elapses, a part of the fabric is peeled off from the outer peripheral surface of the roll and becomes unnecessary waste. If scraps are mixed in the dough, the quality of the coarse noodle strip will deteriorate.

In particular, more dough remains in the dough grains for producing noodles. Since such dough grains are not sufficiently compressed and are sent to the coarse noodle strip forming roll device, a part of the dough tends to stick to the outer peripheral surface of the roll. Moreover, if scrap enters into the irregularities formed on the outer peripheral surface of the roll, the gripping force of the roll is lost in a short time. As a result, the rough noodle strip may be broken. The generation of debris requires frequent cleaning of the rolls, reducing productivity.

Patent document 2 is disclosing the rolling roll by which the fluororesin coating was given to the outer peripheral surface formed in the unevenness | corrugation in order to prevent adhesion to the roll of refuse. The rolling roll of patent document 2 is improving the releasability of dough. However, the rolling roll cannot obtain a sufficient gripping force due to the fluororesin coating. Therefore, the rolling roll cannot gather the dough grains well into the roll gap. As a result, an undesired void called “nest” is easily formed in the rough noodle band, and the rough noodle band may be interrupted.

Patent Document 3 discloses a rough noodle strip forming roll device in which a metal sprayed layer having fine irregularities is formed on the outer peripheral surface of a roll, and the layer is coated with a fluororesin coating. A number of dimples are also formed on the outer peripheral surface of the roll. This rough noodle strip forming roll device improves the releasability of the noodle dough while reducing the slippage of the dough.

However, there is a demand for a coarse noodle strip forming roll device that has a small area where the roll contacts the spherical dough grain and has a sufficient gripping force. In view of the above-described problems, an object of the present invention is to provide a rough noodle strip forming roll device that can reliably capture and collect dough grains in a roll gap. Another object of the present invention is to provide a coarse noodle strip forming roll device that is less likely to generate scrap and that can stably supply the coarse noodle strip.

The present invention includes a drive roll (41), a driven roll (42) having the same diameter as the drive roll, a motor (46) for rotating the drive roll, and a transmission for rotating the driven roll in synchronization with the drive roll. A rough noodle strip forming roll for collecting and rolling the dough grains (82) in a roll gap (G) formed between a driving roll and a driven roll to form a rough noodle strip (84). It relates to the device (10). A number of V-grooves (56) having a depth of 0.6 to 1.0 mm extend in the longitudinal direction on the outer peripheral surfaces of the driving roll and the driven roll, and the driving roll and the driven roll are one of the two rolls. Are rotated at the same speed so as not to face the V groove of the other roll in the roll gap.

In other words, the driving roll and the driven roll are rotated at the same speed so that the V groove of one of the two rolls faces the flat surface of the other roll in the roll gap.

The opening angle (θ) of the V groove is 90 degrees, and the depth (δ) of the V groove is preferably smaller than the size of the roll gap. The V grooves are preferably formed at a predetermined pitch (p), and the predetermined pitch is preferably smaller than the size of the roll gap.

In the rough noodle strip forming roll device of the present invention, the area where the dough contacts the roll is increased by the V groove. In addition, since the V groove of one roll and the flat surface of the other roll are opposed to each other in the roll gap, a highly elastic dough easily bites into the V groove and is easily pulled out. Other effects are described in part in the description that follows.

FIG. 1 is a side view showing a noodle making machine provided with the rough noodle band forming roll device of the present invention. FIG. 2 is a plan view showing an example of the rough noodle strip forming roll device in FIG. 1. FIG. 3 is a side view of the rough noodle strip forming roll device in FIG. 2. FIG. 4 is a perspective view of a driven roll of the rough noodle strip forming roll device in FIG. 2. FIG. 5 is a sectional view partially showing the drive roll and the driven roll in FIG. 6 is an enlarged cross-sectional view of the drive roll and the driven roll in FIG.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an example of a noodle making machine to which the rough noodle band forming roll device of the present invention can be applied. The noodle making machine includes a kneading mixer 1, two coarse noodle strip forming roll devices 10, a plurality of rolling roll devices 30, a noodle strip cutter 4, and a noodle strip cutter 5 in order to produce udon.

The kneading mixer 1 is provided for kneading wheat flour with water and salt to produce a dough. The kneading mixer 1 has a large number of stirring rods 16 attached to a rotating shaft 14. A large number of dough grains 82 are produced by kneading for an appropriate time. When the outlet of the kneading mixer 1 is opened, the dough grain 82 falls and is sent to the two hoppers 6 by the chute 18. The size of the dough grain 82 is 1 to 20 mm depending on the moisture content of the dough.

The two coarse noodle strip forming roll devices 10 are respectively provided immediately below the hopper 6. Although two rough noodle strip forming roll devices 10 are shown in FIG. 1, three or more rough noodle strip forming roll devices 10 may be provided. Each rough noodle strip forming roll device 10 includes a pair of rolls, and a roll gap G is formed between the pair of rolls. The size of the roll gap G is 7 mm to 15 mm, which is the same as the plate thickness of the formed rough noodle strip 84. The dough grain 82 is crushed by the pushing plate 7 and pushed into the roll gap G. The pushing plate 7 is attached to a swingable arm.

The rough noodle strip forming roll device 10 gathers the dough grains 82 in the roll gap G by rotating the pair of rolls. The coarse noodle strip forming roll device 10 presses and hardens the dough grains 82 to form dough chunks, and rolls the dough chunks to form continuous coarse noodle strips 84. The plurality of coarse noodle strips 84 sent out by the coarse noodle strip forming roll device 10 are sent to the aligning roll device 20 by the conveyor 22. The laminating roll device 20 forms a single continuous noodle strip 84 by superposing a plurality of coarse noodle strips 84. The overlapping of the plurality of coarse noodle strips 84 reduces the probability that a defective coarse noodle strip 84 is formed.

The coarse noodle strip 84 is further sent to a plurality of rolling roll devices 30. 1 indicates the direction in which the rough noodle strip 84 is conveyed. The plurality of rolling roll devices 30 are provided to make the rough noodle strip 84 flat and thin step by step. Each rolling roll device 30 includes a pair of rolls consisting of a female roll 32 and a male roll 34. The female roll 32 and the male roll 34 face each other with a predetermined gap. The rolling roll apparatus 30 is provided along with the conveyance direction F. As shown in FIG. The rolling roll device 30 rolls the coarse noodle strip 84 and sends the coarse noodle strip 84 to the next rolling roll device 30.

The knife roll 32 can be rotated by a motor. The male roll 34 rotates following the rotation of the female roll 32. A flange 36 is provided on the female roll 32, and the female roll 32 and the male roll 34 stretch the sandwiched noodle strip 84 only in a direction perpendicular to the rotation axis of the pair of rolls. In this way, the last rolling roll device 30 feeds the noodle strip 86 having a desired thickness and width as the noodle dough to the noodle strip cutting machine 4.

The noodle strip cutting machine 4 has a pair of cutting blade rolls. The noodle strip cutting machine 4 cuts the noodle strip 86 in the length direction by the rotation of the cutting blade roll, and a continuous noodle strip 88 having a desired thickness is formed. The noodle strings 88 are sent to the noodle string cutting machine 5. The noodle string cutting machine 5 cuts the noodle string 88 into a predetermined length.

An example of the coarse noodle strip forming roll device 10 will be described in detail with reference to FIGS. For the sake of simplicity, bearings and the like for supporting the rotating shaft of the roll are omitted in the drawing. As shown well in FIG. 2, the rough noodle strip forming roll device 10 includes a pair of parallel rolls including a drive roll 41 and a driven roll 42. A roll gap G whose size can be adjusted is formed between the pair of rolls. The

rolls

41 and 42 have the same diameter and are arranged side by side.

The rough noodle strip forming roll device 10 further includes a motor 46 and a transmission device 48. The motor 46 rotates the drive roll 41 at a predetermined rotation speed. The drive shaft of the motor 46 is connected to one end of the rotation shaft of the drive roll 41 by a bevel gear. The transmission device 48 synchronizes the driven roll 42 with the drive roll 41 and rotates it at the same rotational speed as the drive roll 41.

The transmission device 48 includes a drive gear 51 and a driven gear 52 that can mesh with the drive gear 51. The drive gear 51 and the driven gear 52 are arranged in parallel and have the same diameter and the same number of teeth. The drive gear 51 is coaxially attached to the other end of the rotation shaft of the drive roll 41. The driven gear 52 is coaxially attached to one end of the rotating shaft of the driven roll 42. Since the gear ratio between the drive gear 51 and the driven gear 52 is 1: 1, the driven roll 42 rotates at the same speed as the drive roll 41. The transmission device 48 may be a sprocket and an endless belt instead of the gear.

The

rolls

41 and 42 are cylindrical metal rotating bodies each having a length l and a diameter d. For example, the

rolls

41 and 42 are made of stainless steel and have a length l of about 400 mm and a diameter d of about 205 mm. Flange 43 is provided at both ends of the rotating body of drive roll 41. The flange 43 restricts the cloth so that it does not protrude in the longitudinal direction of the

rolls

41, 42. Preferably, the diameter of the flange 43 is larger than the value obtained by adding the size of the roll gap G to the diameter d of the drive roll 41. For example, when the size of the roll gap G is less than 15 mm, the diameter of the flange 43 is about 30 mm larger than the diameter d of the drive roll 41. The driven roll 42 is disposed so as to fit between the flanges 43.

The

rolls

41 and 42 have a large number of V grooves 56 extending in the longitudinal direction on the outer peripheral surface. The depth of the V groove 56 is 0.6 mm to 1.0 mm. When the depth of the V-groove 56 is less than about 0.5 mm, the coarse noodle strip forming roll device 10 cannot obtain a sufficient force for pulling the dough in the feeding direction Z. If the depth of the V-groove 56 is somewhat larger than 1 mm, a part of the cloth sticks to the V-groove 56 and remains in it. Such inconvenience occurs particularly when the moisture content of the dough is high.

The depth of the V groove 56 is preferably the same. The same number of V-grooves 56 are formed on the outer peripheral surfaces of the

rolls

41 and 42 at the same pitch. The outer peripheral surface where the V-groove 56 is not formed is a flat surface 58. As well shown in FIG. 5, the

rolls

41 and 42 are rotated so that the V groove 56 of one roll faces the flat surface 58 of the other roll in the roll gap G. In other words, the V groove of one of the

rolls

41 and 42 is rotated so as not to face the V groove of the other roll in the roll gap.

Reference signs θ, δ, and p in FIG. 6 indicate the opening angle, depth, and pitch of the V groove 56. For convenience of explanation, the outer peripheral surfaces of the

rolls

41 and 42 in FIG. 6 are shown by straight lines. The opening angle θ of the V groove 56 is preferably 90 degrees. The pitch p is smaller than the size of the roll gap G. Further, the depth δ is smaller than the pitch p. For example, when the diameter d of the

rolls

41 and 42 is 205 mm and the roll gap G is 10 mm, the depth δ is 0.6 mm and the pitch p is 2.0 mm. Since the drive roll 41 and the driven roll 42 rotate at the same speed, the V-groove 56 of one roll always faces the flat surface 58 of the other roll in the roll gap G.

The broken line in FIG. 6 shows the movement of the dough in the roll gap G. The dough is pushed toward the V-groove 56 of the other roll by the reaction force ν of the flat surface 58 of one roll. In this way, the fabric is smoothly fed out along the tapered surface of the V groove 56. Since the

rolls

41 and 42 are rotating in the delivery direction Z of the rough noodle strip 84, the lump of dough is pulled in the delivery direction Z and rolled. As a result, the dough is formed into a coarse noodle strip 84. The dough that has entered the V-groove 56 slips out along the tapered surface of the V-groove 56 so as to be drawn out to the rough noodle band 84.

Therefore, the

rolls

41 and 42 reliably hold the dough grain 82, gather it in the roll gap G, and press and harden it. A part of the dough does not remain in the V-groove 56 and a lump of dough is formed, and a part of the dough does not peel off from the surface layer of the dough. The lump of dough is rolled to form a coarse noodle strip 84 and fed out. As a result, voids called “nests” are not formed in the rough noodle band 84.

The flat surfaces 58 of the

rolls

41 and 42 have a surface roughness of several μmRa to several tens of μmRa. The entire outer peripheral surface of the

rolls

41 and 42 may be uniformly coated with fluororesin. Since the fluororesin coating improves the releasability of the cloth, even if the

rolls

41 and 42 are used for a long time, the cloth does not fill minute concave portions on the outer peripheral surface. Therefore, the gripping force of the

rolls

41 and 42 does not decrease.

The rough noodle strip forming roll device 10 of the present invention is not intended to be limited to the disclosed form. Many modifications and variations are possible with reference to the above description. The present invention can be used for the production of noodles such as udon, ramen, soba and pasta.
