Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for continuously kneading dough for noodles, confectionery, etc., and in particular, to a method and apparatus for continuously kneading dough for noodles, confectionery, etc. While the fabric is passing through, the circumferential speed of the rollers forming at least a part of the set is changed periodically, and the fabric passing through this set is stopped when the rollers are at a low circumferential speed, and when the rollers are at a high circumferential speed, the fabric is stopped at the next roller speed. By feeding the dough into a set of rollers, the cross-sectional area has substantially increased when it is stagnant, and as it passes through this set, it is rolled to knead the dough, and the dough is continuously fed from the last set of rollers to the next process. .

Dough kneading was done to form a gluten network structure with sufficient fineness and uniformity to make dough with excellent extensibility and texture. , is done by kneading with hands and feet. Traditionally, the method for kneading noodle dough is to put raw flour, water, and optional additives into a large container, and then use rotary blades to stir these ingredients to form dough, which is then continued to be stirred. The practice was to knead the dough. However, when it comes to kneading dough like this,
There is a problem in that gluten activation tends to be insufficient because sufficient pressure is not applied to the dough and, therefore, the action of kneading the dough is poor. In addition, since the dough is kneaded in a large container and then taken out from the container and fed to the next process, there is a problem that it is difficult to continuously feed the dough to the next process. It was hot.

Therefore, this invention was made to solve the above-mentioned conventional problems, and the purpose of this invention is to improve the network structure of gluten by kneading the dough sufficiently and promoting the activation of gluten. It is an object of the present invention to obtain a dough that is sufficiently fine and uniform and has excellent extensibility and texture, and an object of the present invention is to continuously supply the kneaded dough to the next step.

That is, this application discloses a set of rollers 1 and 1 consisting of a pair of parallel rollers A and B, as shown in the figure.
A plurality of rollers 2, 3... are lined up, and the fabric 6 is sequentially passed between the rollers A and B of each set 1, 2, 3..., and at least some of the sets 2, 3... are formed during the passage. By periodically changing the circumferential speed of rollers A and B, the fabric 6 passing through the sets 2, 3, etc. is made to stagnate when rollers A and B have a low circumferential speed, and to stop when rollers A and B have a high circumferential speed. By sending the dough to the group of 6, the cross-sectional area has substantially increased due to polymerization, adhesion, etc.
The specified invention is a continuous dough kneading method characterized in that the dough is rolled and fed while passing through the sets 2, 3, etc. while kneading the dough 6, and furthermore, a pair of parallel rollers A are provided. A plurality of roller sets 1, 2, 3... consisting of rollers A and B are arranged in the vertical direction, and at least some of the roller sets 2, 3... of the plurality of roller sets 1, 2, 3... , B is a continuous dough kneading device characterized by being provided with a peripheral speed changing device 7 that periodically changes the peripheral speed of the dough.

The present invention will be explained below based on the drawings.
FIG. 1 is a diagram showing the principle of the invention. A,
B is a pair of rollers, which constitute a set of rollers. Five sets are used as shown by symbols 1 to 5, and the first set 1 to the fifth set 5
are arranged sequentially in the vertical direction. Each group 1-5
The axes of rollers A and B are horizontal and parallel to each other, and the axes of rollers A and B are oriented in the same direction in each set 1 to 5.
The horizontality and parallelism of the axes do not need to be exact.

2nd, 3rd, 4th set 2, 3, 4 rollers A, B
The circumferential speed changes periodically,
Moreover, the timing of peripheral speed change is different between upper and lower sets 2 and 3 and sets 3 and 4. That is, in the illustrated case, the third set 3 has a long arrow indicating the rotational direction of the rollers A and B, and the second and fourth sets 2 and 4 have a fast circumferential speed of the rollers A and B and have short arrows. shows a state in which the circumferential speeds of rollers A and B are slow.

When the dough 6 made by stirring raw flour, water, and additives if necessary is supplied from above to the first set 1, the dough 6 is transferred to the second set 2 by the rotation of the rollers A and B. supplied to In the second set 2, the circumferential speed of rollers A and B is slow, so the third set
The amount of dough supplied to the second set 3 decreases, and the dough 6 stagnates and accumulates above the second set 2. Here, the fabric 6 polymerizes or sticks, so that the cross-sectional area of the fabric 6 increases substantially. next,
When the circumferential speed of rollers A and B of the second set 2 increases,
Since the amount of dough 6 supplied to the third group 3 increases,
On the upper side of the second set 2, the fabric 6 is
The stagnation is resolved, the circumferential speed of the rollers A and B of the third set 3 is reduced, and the fabric 6 is stagnated and accumulated on the upper side of the third set 3, as shown by the chain line.

When the circumferential speed of the rollers A and B of the second set 2 increases, the fabric 6 that had been accumulated on the upper side of the second set 2 is drawn between the rollers A and B and compressed, but the Since the cross-sectional area between A and B is smaller than the cross-sectional area of the fabric 6 that was accumulated on the upper side, all of the fabric 6 that was accumulated on the upper side of the second set 2 is transferred to rollers A and B at the same time. Don't be drawn in,
A part of it is sequentially drawn between rollers A and B,
The others remain above the second set 2, and this remainder takes the form of a gradual decrease. At this time, there is a space inside the fabric 6 between the fabric 6 that remains on the upper side of the second set 2 and is subsequently drawn between rollers A and B, and the fabric 6 that is first drawn between rollers A and B. Internal friction acts on the fabric 6, and a compression effect between rollers A and B is added to give a kneading effect to the fabric 6.

When the circumferential speed of the rollers A and B of the second set 2 becomes faster, the circumferential speed of the rollers A and B of the third set 3 becomes slower, and similarly to the above, the fabric 6 is placed on the upper side of the third set 3 as shown in chain lines. It accumulates as shown in . Then, as the circumferential speed of rollers A and B of the third set 3 increases, these rollers A,
The dough 6 is kneaded by B in the same manner as above, and the fourth set 4
supplied to In the fourth set of rollers A and B, the dough 6 is kneaded in the same manner as described above, and
From there, it is supplied to the next process, for example, the rolling process in the noodle making process. Thus, dough 6
During the period from the first group 1 to the fifth group 5, the ingredients are kneaded and thoroughly kneaded, especially in the second, third, and fourth groups 2, 3, and 4.

2 to 6 show a first embodiment of the invention. FIG. 2 shows the first to fifth sets 1, 2, 3, 4, and 5 used in this first embodiment and the respective rollers A and B. The axes of the rollers A and B are The sets 1, 3, and 5 of the sets 1, 3, and 5 face the same direction, and the sets 2 and 4 of the 2nd and 4 faces the sets 1, 3, and 5 of the 1st, 3, and 5 when viewed from above. and facing at right angles. As a result, the first to fifth sets 1, 2, 3,
4 and 5 alternately intersect at right angles from above. The rollers A, B of each set 1, 2, 3, 4, 5 are connected to the machine frame 10, as shown in FIGS. 3 to 6.
will be installed in

A frame plate 12 is installed between the pillars 11 of the machine frame 10,
A rotating shaft 13 fixed to each roller A, B is supported between the frame plates 12. In each set, gears 14a, 14b that mesh with each other are fixed to each rotating shaft 13 of both rollers A, B, and these gears 14a, 1
4b allows both rollers A and B of the same set to rotate synchronously. Further, a chain sprocket 15 is fixed to the rotating shaft 13 of each set of rollers B, respectively. The chain sprocket 15 of the first set 1 is connected to the output shaft 16 of the first gearbox 16.
To the chain sprocket 17 fixed concentrically to a,
The chain sprockets 15 of the second set 2 are connected by a chain 18, and the chain sprockets 20 of the third set 3 are connected by a chain 21 to a chain sprocket 20 eccentrically fixed to the output shaft 19a of the second gear box 19. The chain sprocket 15 is connected to a chain sprocket 22 eccentrically fixed to another output shaft 19b of the second gear box 19.
Connected by 3. Furthermore, the chain sprocket 15 of the fourth set 4 is connected to the third gear box 2.
The chain sprocket 15 of the fifth set 5 is connected by a chain 26 to a chain sprocket 25 eccentrically fixed to the output shaft 24 a of the third gear box 24 . It is connected to a chain sprocket 27 by a chain 28.

Since the chains 21, 23, 26 are engaged with the eccentric chain sprockets 20, 22, 25, the tensions of the chains 21, 23, 26 change. The chain tensioner 29 engages. As shown in FIGS. 3 and 5, the chain tensioner 29 has an arm 29b whose base end is pivotally attached to the machine frame 10 and an idler sprocket 29a attached to its tip, which is biased by a tension spring 29c. It consists of

A chain sprocket 31 is attached to the input shaft 16b of the first gearbox 16, and a second gearbox 19 is attached to the input shaft 16b of the first gearbox 16.
Chain sprockets 32, 3 are attached to the input shaft 19c of
3. Chain sprockets 34 and 35 are each fixed to the input shaft 24c of the third gear box 24,
Chain 3 is between chain sprocket 31 and 33.
6. A chain 37 is stretched between the chain sprockets 32 and 34, and a chain 41 is stretched between the chain sprocket 35 and a chain sprocket 39 fixed to the output shaft 38a of the motor 38. passed on. Therefore, from the motor 38 to the gear 14
In a series of driving force transmission systems leading to a and 14b,
The chain sprockets 20, 22, 25 are eccentric, so that the second, third, fourth sets 2,
The circumferential speeds of rollers A and B of rollers 3 and 4 are changed periodically, and this configuration constitutes the circumferential speed changing device 7 of the present invention.

Further, a cover 42 fixed to the machine frame 10 is installed on the rollers A and B of each of the sets 1 to 5, and the dough 6 is kneaded inside this cover 42. A cover 42 is in sliding contact with the upper and lower parts of the outer periphery of the rollers A and B, and the outer circumferential surface of each set of rollers A and B on the opposite side from the opposing portion is exposed from the cover 42, and the roller On the lower side of A, B, the cover 42 comes into sliding contact with the rollers A, B at a position directly below the rotating shaft 13, and scrapes off the fabric adhering to the surfaces of the rollers A, B. 42a is the scraper, and the cover 4
Forms part of 2.

The driving force of the motor 38 is transmitted to the third gear box 24 via its output shaft 38a, chain sprocket 39, chain 41, and chain sprocket 35.
is transmitted to the input shaft 24c and its chain sprocket 34. As a result, the third gearbox 2
The two output shafts 24a and 24b of No. 4 rotate to rotate the chain sprockets 25 and 27, respectively. Then, the chains 26 and 28 are driven, the rotating shaft 13 of the rollers B of the fifth set 5 is rotated by the chain sprocket 15, and the rollers B of the fourth set 4 are rotated.
A rotating shaft 13 of the rotating shaft 13 is rotated by a chain sprocket 15. When the rotating shafts 13 of the rollers B of the fourth set 4 and the fifth set 5 rotate, the rollers B of both sets 4 and 5 rotate, and this rotational force is applied to the gear 14.
b, the rotation shaft 13 of each roller A via the gear 14a
The rollers A of both sets 4 and 5 are also rotated via. Here, since the chain sprocket 27 is concentric with the output shaft 24b, the rollers A and B of the fifth set 5 always rotate at a constant circumferential speed, while the rollers A and B of the fifth set 5 always rotate at a constant circumferential speed.
The rollers A and B are connected to the chain sprocket 25.
is eccentric with respect to the output shaft 24a, so the circumferential speed changes periodically.

When the input shaft 24c of the third gearbox 24 rotates, the chain sprocket 34 rotates, and the chain 37 is driven to connect the input shaft 19c of the second gearbox 19 and the chain sprocket via the chain sprocket 32. 33. As a result, the output shafts 19a and 19b of the second gearbox 19 rotate, causing the chain sprockets 20 and 22 to rotate, thereby rotating the chain sprockets 20 and 22.
1 and 23, the rotating shaft 13 of the roller B of the third set 3 is rotated by the chain sprocket 15, and the rotating shaft 13 of the roller B of the second set 2 is rotated by the chain sprocket 15. Ru. When the rotating shafts 13 of the rollers B of the second set 2 and the third set 3 rotate, the rollers B of both sets 2 and 3 rotate, and this rotational force is applied to the respective rollers A through gears 14a and 14b. Both sets 2 and 3 are connected via the rotating shaft 13 of
Also rotate roller A. Here, the rollers A and B of both sets 2 and 3 are connected to chain sprockets 22 and 20.
are eccentric with respect to the output shafts 19b and 19a, so the circumferential speed changes periodically. Therefore, the second
The circumferential speeds of the rollers A and B of the third and fourth sets 2, 3 and 4 change periodically, but the rollers A and B of the second and fourth sets 20 and 4 have chain sprockets 20 and 25. Since the eccentric phases of the rollers A and B of the third set 3 are the same, the circumferential speed changes synchronously.
Since the eccentric phase of the chain sprocket 22 is opposite to that of the chain sprockets 20 and 25, the timing of peripheral speed change is opposite to that of the rollers A and B of the second and fourth sets 2 and 4. It appears.

When the chain sprocket 33 rotates due to the rotation of the input shaft 19c of the second gear box 19, the input shaft 16b of the first gear box 16 rotates via the chain 36 and the chain sprocket 31, and its output shaft 16a rotates. and sprocket 17
rotates. This drives the chain 18, rotates the chain sprocket 15 of the first set 1, and rotates the rotating shaft 13 of the roller B thereof. When this rotating shaft 13 rotates, the rollers B of the first set 1 rotate, and the rollers A also rotate via the gears 14b, 14a and the rotating shaft 13. The rotation of the rollers A and B of the first set 1 is controlled by the chain sprocket 17.
Since it is arranged concentrically with respect to the output shaft 16a, it always rotates at the same circumferential speed.

Thus, the driving force of the motor 38 causes the first to
Each roller A, B of five sets 1, 2, 3, 4, and 5 rotates. Therefore, the fabric is fed between the rollers A and B of the first set 1 from above. This dough is made by stirring raw flour, water, and necessary additives in advance. The supplied dough is kneaded and kneaded while passing between rollers A and B of sets 1 to 5, 1, 2, 3, 4, and 5, similar to the principle diagram shown in FIG. However, in this embodiment, the rollers A and B of the second group 2 and below are the rollers A and B of the upper group.
Because the fabric is oriented in a direction perpendicular to the upper group, the dough that has been kneaded and pressed in the upper group becomes flat, but in the lower group, the flat state is broken and the dough is kneaded again from a different direction. Rare and pressurized. The dough that is repeatedly kneaded and pressurized from different directions in this way is sufficiently kneaded to form a network structure of gluten in multiple directions, and the network structure has sufficient fineness and uniformity. It is formed.

In this example, the rollers A and B used had the same diameter from one end to the other, but one roller A of the same set was used that was thicker in the center. The other roller B may be tapered at the center, and the number of roller sets 1 to 5 may be six or more. Also, chain sprockets 20, 22,
If you change the eccentricity and eccentricity phase of 25, the second, third,
It is possible to change the circumferential speed change rate and the timing of circumferential speed change of the rollers A and B of the four sets 2, 3, and 4. Further, the space surrounded by the cover 42 above the second, third, and fourth sets 2, 3, and 4 is filled with fabric, and the fabric is further fed from the rollers A and B above the cover 42. For example, since the dough is pressurized between the upper and lower pairs, the kneading effect of the dough is further enhanced. Furthermore, if all or some of the rollers A and B of the second, third, and fourth sets 2, 3, and 4 are eccentrically set so that the distance between the rollers A and B varies widely,
The kneading action on the dough also increases, and the kneading effect on the dough becomes higher. In this case, the scraper 42a that is in sliding contact with the rollers A and B is movable so as to follow the movement of the circumferential surfaces of the rollers A and B, and is always biased so that the scraper 42a is in sliding contact with the circumferential surfaces of the rollers A and B. I'll keep it.

FIG. 7 shows a second embodiment of the present invention, in which the timings at which the circumferential speeds of rollers A and B of the second group 2 change are different, and This is an example in which the 3rd and 4th groups 4 are configured in the same way, but the 2nd, 3rd, and 4th groups 2, 3, 4
It is also possible to configure some of the sets in this way. That is, a total of two chain sprockets 15 fixed to the rotation shafts 13 of both rollers A and B, and each chain sprocket 45 of two rotation output shafts 44 connected to the same drive source are connected by a chain 46. Both chain sprockets 45 are connected individually and eccentrically in the same direction with respect to each rotating output shaft 44.
Therefore, in the illustrated state, the circumferential speed of roller A is high and the circumferential speed of roller B is small, and both rollers A and B
Since the circumferential speeds of the rollers A and B are different, the internal friction of the fabric passing between the rollers A and B increases. As a result, the kneading effect on the dough is increased, so that the dough is kneaded even more thoroughly. The circumferential speed between rollers A and B can be changed by eccentrically setting rollers A and B themselves, or by connecting motors to rollers A and B individually and changing the rotation speed of the motors. It can also be done by In addition,
In the case of FIG. 7, the positions of the chain sprocket 45 and the rotating output shaft 44 are set so that they do not interfere with other sets of rollers, such as in the lateral direction of rollers A and B. , may not necessarily be in the illustrated position. The other structure and operation are the same as the first embodiment.

8 and 9 show a third embodiment of the present invention, in which motors M1, M2, M3, M4, and M5 are individually connected to roller sets 1, 2, 3, 4, and 5, respectively. This is an example in which the circumferential speeds of each set of rollers A and B are controlled by individually controlling each motor, as in the first embodiment. That is, a motor M1 is connected to the rollers of the first set 1, and a rotation speed controller C1 connected to a command circuit D1 is connected to the motor M1. T1 is a tacho generator, which feeds back the rotational speed of rollers A and B to a rotational speed controller C1. This circuit is connected to another motor M2.
~M5 is also provided individually, and the command circuits D1 to D5 include a control for sequentially changing the rotation speed of the motors M2, M3, and M4, and changing the rotation speed of the motors M1 and M5 as necessary. Connect device G. Thus, the control device G also serves as the circumferential speed changing device 7 of the present invention. The fifth set 5 is provided with a detector S for detecting the amount of dough supplied to the next process, and feeds back the signal to the rotation speed controller C5 to keep the amount of dough supplied to the next process constant. As a result, as shown in FIG.
As shown by the broken line, the circumferential speed is basically constant, and the amount of fabric entering the first group and the amount of fabric coming out of the fifth group are constant. Also, by changing the phase of change in circumferential speed between the second and fourth sets 2 and 4 and the third set 3, when the circumferential speed of the second and fourth sets 2 and 4 shown by the solid line is large, the chain line The circumferential speed of the third set 3 shown by is made small,
Moreover, the magnitudes of these circumferential velocities are reversed. The transition time between large and small circumferential speeds is also set in advance in the control device G, so that it can be changed as necessary.

Thus, according to this embodiment, by separately providing motors M1 to M5 for each set 1 to 5 and controlling each motor individually, it is possible to freely change the rotational speed and circumferential speed of each roller A and B. Can be set.

As is clear from the above, according to this invention,
While the dough passes through the set of rollers, the rollers repeatedly apply a kneading action and a pressure action to thoroughly knead the dough. Therefore, it is possible to promote the activation of gluten and form a sufficiently fine and uniform gluten network structure in multiple directions, making it possible to obtain dough with excellent extensibility and texture. . Further, according to this invention, since the dough passes through the set of rollers continuously, it is possible to continuously supply the kneaded dough to the subsequent process, for example during the noodle making process. This makes it suitable for supplying dough to continuous rolling processes, etc.
