Akita

Background art

As this kind of kneading element, Japanese Patent Publication No. 5-388828 discloses a pair of long and short semi-elliptical blades connected in series, and a side surface from a bottom edge to an upper surface of both blades. Is a parabolic inclined surface that becomes gradually steeper from the front to the rear in the rotation direction, and a deep cliff-shaped erected surface is formed on the back in the rotation direction behind one of the blades in the rotation direction. A kneading element is disclosed in which a side end is continuous with the bottom of an erecting surface of one of the blades, and a shallow cliff-shaped erecting surface is formed on the back side in the rotational direction on the other side. When the kneading element is rotated in the container, the material and the dough are moved upward by the long inclined surface of the blade while moving to the peripheral wall of the container, and are dropped from the standing surface to perform mixing and kneading. A vacuum air layer is formed between the dough mass and the kneading element during kneading on the back of the standing surface of the kneading element, so that the force for rotating the dough element acts and the dough adheres to the container bottom wall and the kneading element. Even when kneading a large mass of dough with a diameter equal to or greater than the radius of the bottom wall of the container, the dough rotates together with the kneading element due to the adhesion of the dough to the kneading element, and kneading is performed. The trouble of being lost is prevented. Generally, rolling of the dough mass is performed by centrifugal force and rolling friction received by the rotation of the kneading element, and the rolling friction increases with the progress of hydration of the dough. When kneading a large mass of dough with a diameter equal to or greater than the radius of the bottom wall, if the rolling friction exceeds the centrifugal force acting on the mass of dough, the dough adheres to the kneading element and rotates with the kneading element. Will not be performed. The technology disclosed in the above-mentioned publication reduces the rolling friction by creating the above-mentioned depressurized air layer, and prevents the dough from adhering to the kneading element by maintaining the centrifugal force larger than the rolling friction. It is possible to knead large masses of dough with a diameter larger than the radius of the dough.

However, when kneading a larger mass of dough, the weight and surface area of the mass of dough increase, making it difficult to prevent the dough from adhering to the kneading element even with the technique disclosed in the above publication. .

The kneading of the dough mass is performed by compressing, rotating, folding, etc. of the dough mass. The essence of the kneading operation is to compress the dough, so that the dough mass is continuously compressed. However, it is desirable to knead the dough mass promptly, Disclosure of the invention

The present invention has been made in view of such a point, and the object thereof is that the distance from one point on the side surface of the kneading element to the rotation center axis is constantly increased as one rotation is performed. In this way, the centrifugal force acting on the dough is always promoted, so that even a large dough mass having a diameter much larger than the radius of the container bottom wall can adhere to the kneading element. In addition to kneading the dough satisfactorily, the dough is continuously compressed to knead the dough mass quickly.

In order to achieve the above object, a kneading element of a kneading apparatus of the present invention includes a container of a kneading apparatus including a container having a bottom wall and a peripheral wall rising from a peripheral edge of the bottom wall. A kneading element which is arranged so as to stand up from the container and rotates relative to the container, comprising a side surface formed over the entire periphery, and a top surface having a peripheral edge connected to an upper edge of the side surface. , Including rotation center axis When cross-sectioned in a plane, the distance from one point on the side surface to the center axis of rotation is formed so as to decrease or be constant from the bottom to the top surface.The side surface is a plane perpendicular to the center axis of rotation. It is formed so that the distance from one point on the side surface to the center axis of rotation always increases during one rotation.

When the kneading element is rotated in the container, the material and the dough are lifted while moving to the peripheral wall of the container by the side surface, dropped by gravity, and the movement is repeated to repeat mixing and mixing. Kneading is performed. In addition, the kneading element rushes into the lower part of the dough so as to drive the dough into the wedge, thereby exerting a force to rotate the dough in the dough mass. Kneading proceeds. In that case, the distance from one point on the side of the kneading element to the rotation center axis is

Since it is formed so as to always increase during one rotation, the centrifugal force constantly acting on the fabric is promoted, and this centrifugal force easily overcomes rolling friction. As a result, the dough is prevented from adhering to the kneading element, and even a large dough mass having a diameter greatly exceeding the radius of the bottom wall of the container can be kneaded well without adhering to the kneading element. You. In addition, since the dough is continuously compressed, kneading is promoted, and the dough mass is quickly kneaded.

The kneading element of the kneading apparatus of the present invention is formed such that the distance from one point on the side surface of the kneading element to the rotation center axis is always increased in one rotation, so that the centrifugal element always acting on the dough The centrifugal force helps to overcome the rolling friction. Therefore, the dough is prevented from adhering to the kneading element. Even a large dough piece having a diameter greatly exceeding the radius of the container bottom wall can be satisfactorily kneaded without adhering to the kneading element. In addition, since the dough is continuously compressed, the kneading is promoted, and the dough can be kneaded quickly. BRIEF DESCRIPTION OF THE FIGURES

Hereinafter, embodiments of a kneading element and a kneading device of the present invention will be described with reference to the drawings. FIG. 1 shows a kneading apparatus 100 of the first embodiment. This kneading apparatus 100 comprises a container 110, a kneading element 120 arranged in the container 110, and a kneading device. Rotating motor that rotates at least one of the child 120 and the container 110 ' Moving means (not shown). The kneading apparatus 100 includes an apparatus main body (not shown), and the apparatus main body is provided with a container 110 and a rotary drive pot. The container 110 includes a bottom wall 111 and a peripheral wall 112 rising from the periphery of the bottom wall 111. The shape of the container 110 is not limited, but it is preferable that the bottom wall 111 is formed in a circular shape and the peripheral wall 112 is formed in a cylindrical shape, so that kneading can be performed evenly. The kneading element 1 20 has a virtually provided rotation center axis 1 2 1, and the kneading element 1 2 0 has the rotation center axis 1 2 1 in the container 1 1 0 and the bottom wall 1 1 1. It is arranged to stand up from the center. It is preferable to raise the rotation center axis 1 2 1 from the center of the bottom wall 1 1 1, so that kneading can be performed evenly. In this embodiment, the kneading element 120 is rotated by the rotation driving means. The rotation drive means is a motor and a deceleration mechanism provided as necessary.The output shaft coincides with the rotation center axis 1 2 1 of the kneading element 1 2 0 from the center of the bottom wall 1 1 1 of the container 1 1 0. And it is connected to the kneading element 120. The present invention includes an embodiment in which the container is rotated by the rotary drive means, and an embodiment in which the kneading element and the container are rotated by the rotary drive means, in the latter case. In both cases, the ratio of the number of rotations is not limited. Further, the rotation speed may be constant or may be varied.

As shown in FIGS. 2 to 5, the kneading element 120 has a side surface 122 formed over the entire circumference and a top surface 123 having a peripheral edge connected to an upper edge of the side surface 122. It has. As shown in FIGS. 4 and 6, when the side surface 122 is cross-sectioned along a plane including the rotation center axis 121, the side surface 122 extends from a point on the side surface 122 to the rotation center axis 121. The distance R 1 is configured to decrease or be constant from the bottom toward the top surface 123. As shown in Fig. 5 and Fig. 7, when the side surface 1 2 2 is cut along a plane orthogonal to the rotation center axis 1 2 1, the point from one point on the side surface 1 2 2 to the rotation center axis 1 2 1 Distance R 2 is one rotation It is formed so as to always increase in the future. Top surface 123 may be flat or curved.

As shown in FIGS. 5 and 7, in the first embodiment, the side surface 122 is formed so as to form a logarithmic spiral when cross-sectioned in a plane perpendicular to the rotation center axis 121. FIG. 7 shows a continuous part 124 described later, and a part of the logarithmic spiral is represented by a dotted line to facilitate understanding. Here, the logarithmic spiral is a line represented by 1 o g r = a S (a is a constant) in polar coordinates. In this case, if polar coordinates are taken with the rotation center axis 1 2 1 as the origin, the side surface 1 2 2 is expressed as 1 ogr = a θ when cross-sectioned with a plane orthogonal to the rotation center axis 1 2 1 It is formed by a logarithmic spiral. Here, the logarithmic spiral is also called a conformal spiral, and when the constant a = l. 6 18 = (V ~ 5 + 1) Z2, it is called a golden spiral.

As shown in FIGS. 4 and 6, the side surface 122 is formed so as to be a straight line, a curved line, or a broken line connecting these when sectioned along a plane including the rotation center axis 121.

The kneading element 120 of the first embodiment is further rotated. When a cross section is taken along a plane perpendicular to the central axis 122, the distance R from a point on the side surface 122 to the rotational central axis 122 is A continuous portion 124 that fills the angled portion formed between the portion where the value 2 is maximum and the portion where the value 2 is minimum is provided to reduce the variation of the distance R 2.

In the kneading element 120 of the first embodiment, a fluororesin is coated on the surface to make the surface uniform and smooth, thereby reducing the rolling friction. I have. The surface may be polished. The present invention includes an embodiment of a kneading element which does not perform fluorine resin coating or puff polishing.

Therefore, in the case of the first embodiment described above, for example, in the case of manufacturing bread dough, for example, flour, yeast, sugar, salt, water, butter, etc. are placed in the container 110. The kneading element 120 is placed inside the container 110, and the distance from one point on the side surface of the kneading element 120 to the rotation center axis 122 in the container 110 is constantly increasing in one rotation (white). (In the direction indicated by the arrow in the drawing)), these materials are moved upward by the side wall 122 while moving to the peripheral wall 112 of the container 110, and dropped by gravity. The materials are mixed by repeating the above steps. As the mixing of the ingredients progresses, a dough mass is formed, and the dough mass is raised while moving to the peripheral wall 1 12 of the container 110, dropped by gravity, and this movement is repeated. The dough mass is kneaded. In addition, the kneading element 120 rushes into the lower part of the dough so as to drive a wedge into the lower part, so that the force for rotating the base of the dough acts (for example, the direction indicated by the arrow in FIG. 6). This causes the dough to move up and down and convection, and kneading proceeds. In that case, the distance from one point on the side surface 1 2 2 of the kneading element 1 2 0 to the rotation center axis 1 2 1 is formed so as to always increase in one rotation, so it always acts on the dough The centrifugal force is promoted, and this centrifugal force can easily overcome the rolling friction. As a result, the dough is prevented from adhering to the kneading element 120, and even if a large dough mass having a diameter greatly exceeding the radius of the bottom wall 111 of the container 110, the kneading element 1 can be prevented. Good kneading without adhering to 20. In addition, since the dough is continuously compressed, the kneading is promoted, and the green mass is quickly kneaded.

The present invention is directed to an embodiment in which, when the side surface is sectioned by a plane perpendicular to the rotation center axis, the distance from one point on the side surface to the rotation center axis always increases in one rotation. Includes all. Among them, in the above embodiment, the side surface 122 is formed so as to form a logarithmic spiral when sectioned along a plane orthogonal to the rotation center axis 121. By doing so, the distance R 2 from one point on the side surface 1 2 2 of the kneading element 1 2 0 to the rotation center axis 1 2 1 smoothly increases without any discontinuity during one rotation. The present invention The side shape of the kneading element is preferable.

The present invention is formed such that when the side surface is cross-sectioned at a plane including the rotation center axis, a distance from a point on the side surface to the rotation center axis decreases or is constant from the bottom to the top surface. Including all the embodiments described. Among them, in the above embodiment, the side surface 122 is formed so as to be a straight line, a curved line, or a polygonal line connecting these when the cross section is taken along the plane including the rotation center axis 121, as described above. Then, since the side 1 2 2 does not have a discontinuity or a step in the height direction, the side 1 2 2 moves the material or the dough to the peripheral wall 1 1 2 of the container 1 1 0. When moving up, the material and dough move smoothly.

The present invention includes an embodiment in which a continuous portion is not provided at an angled portion. On the other hand, in the above embodiment, the distance R 2 from one point on the side surface 122 to the rotation center axis 121 when the section is taken along a plane perpendicular to the rotation center axis 121 is also maximum. A continuous portion 124 that fills the angled portion formed between the portion that becomes the minimum portion and the portion that becomes the minimum and reduces the variation in the distance R2 is provided. In this way, the material and the cloth do not easily adhere to the corner, which facilitates cleaning and is preferable in terms of hygiene.

Hereinafter, other embodiments will be described. In each embodiment, the explanation of the first embodiment is basically cited together with the reference numerals attached to the respective members, and only the points different from those of the first embodiment will be described. FIG. 8 shows a cross section of the kneading element 120 of the second embodiment.

(The hatched area corresponds to the cross section). The side surface 1 2 2 of the kneading element 1 2 0 has a distance R 2 from a point on the side surface 1 2 2 to the rotation center axis 1 2 1 when the cross section is taken along a plane perpendicular to the rotation center axis 1 2 1. Is formed by the first and second rounds of a circle consisting of a series of circles whose radii increase in accordance with the Fibonacci sequence and are connected by tangential tangents. ing. The Fibonacci sequence is a number that starts at 1, 1 and is the sum of the previous two numbers. In the sequence, represented by F _n = F n-i + F n-2. Specifically, 1, 1, 2, 3

5, 8, 13, 13, 21, 34, 55, 89, and so on. Therefore, a line corresponding to the first and second rounds of a plurality of circles, which are formed by sequentially tangently connecting the quarter circles of a plurality of circles whose radius increases in accordance with the Fibonacci sequence, The radii are lc, 1c, 2c, 3c, 5c, 8c, 13c, 21c, 34c, 55c, 89c- c is a constant), and connect one-quarter of each circle continuously so that there is no step, and connect any one of the second and subsequent rounds of the line It is a line. In this way, the ratios of adjacent radii are 1, 2, 1.5, 1.67, 1.6, 1..

As we approach 1618, such as 625, 1.615, we can approximate the golden spiral. In this case, the reason for excluding the first lap is that the deviation is large compared to 1.618.

With the kneading element 120 of the second embodiment, a line approximating a conformal spiral having a spiral orbit using the golden ratio of the logarithmic spiral is obtained. Therefore, the distance R 2 from one point on the side surface 1 2 2 of the kneading element 1 2 0 to the rotation center axis 1 2 1 increases smoothly without any discontinuity in one rotation, The side shape of the kneading element of the present invention is preferable. In this case, a spiral approximation line can be obtained by combining the circles, so that the kneading element 120 can be easily manufactured. Other functions and effects are the same as those of the kneading element 120 of the first embodiment, and thus the description is omitted.

FIG. 9 shows a cross section of the kneading element 120 of the third embodiment. The side surface 122 is formed so as to have a step shape when sectioned along a plane including the rotation center axis 122. In this way, the kneading element 120 can be manufactured by stacking the member elements 120a to 120f having a constant cross-sectional shape in the height direction, so that the manufacturing is easy. is there. The height of each step of the stairs may be equal, but unevenness may cause irregular movement of the fabric. Wear. Other functions and effects are the same as those of the kneading element 120 of the first embodiment, and thus the description is omitted.

FIG. 10 shows the kneading element 120 of the fourth embodiment, and FIG. 11 shows the kneading element 120 of the fifth embodiment. Irregularities are formed on at least one of the side surface 122 and the top surface 123 of the kneading element 120. That is, the kneading element 120 of the fourth embodiment is provided with dimple-shaped dimples 125 in the form of scattered points, and the kneading element 120 of the fifth embodiment is provided with grooves 12 6 are provided, thereby forming irregularities. By doing so, the area of the kneading element 120 that contacts the dough is reduced, so that the rolling friction of the dough mass is reduced, and the centrifugal force can easily overcome the rolling friction. This prevents the dough from adhering to the kneading element 120, and enables the kneading element to be used even with a large dough mass having a diameter that greatly exceeds the radius of the bottom wall 111 of the container 110. Kneaded well without adhering to 120. Other functions and effects are the same as those of the kneading element 120 of the first embodiment, and thus the description is omitted.

FIG. 12 shows a kneading element 120 of the sixth embodiment. In the kneading element 120, a projection 127 is provided on at least one of the top surface 123 and the side surface 122. The projections 127 may be fixed to the kneading element 120, or may be detachably provided to the kneading element 120 by screwing or the like. The protrusions 127 may be formed of a material having high rigidity, or may be formed of a material which is easily elastically deformed. The function of the projection 127 will be described.

The dough mass rises and descends due to the rotating kneading element 120, and the dough in the dough mass rises and sinks and convects. In this case, for example, when the viscosity of the dough is low due to the fact that it contains a large amount of fats and oils, the dough is sagged, and the dough mass is substantially umbrellad around the rotation center axis 122 of the kneading element 120. Although the dough mass rotates almost around the center axis of rotation 1 2 1, the dough mass does not rise and fall, and the convection of the dough mass does not occur, which may make kneading difficult. . with this Does not expect the effect of kneading, and it takes too long to finally knead the dough mass. With the use of the kneading element 120 of the sixth embodiment, when the dough mass tries to enter such a state, the protrusion 127 catches the dough mass and exists between the dough mass and the protrusion 127. Using the difference in rotational speed around the rotation center axis 1 2 1, the dough is given an opportunity to start moving up and down along the side surface 1 2 2 of the kneading element 1 20, To give them the opportunity to rotate. As a result, the lifting and lowering of the dough mass and the convection of the dough in the dough mass continue without enduring, and kneading proceeds.

When the dough is slippery, for example, because it contains a large amount of fats and oils, the dough mass slides on the side surface 122 or the top surface 123 of the kneading element 120 to escape. In this case, the kneading action by compression cannot be expected, and it takes too much time to finally knead the dough mass. When the kneading element 120 of the sixth embodiment is used, when the dough mass is about to enter such a state, the projections 127 catch the dough mass and stop slipping, and the kneading material 1 2 Gives a trigger to start the ascending and descending movement along the side 1 2 2 of 0 and to rotate the dough in the dough mass. As a result, the lifting and lowering of the dough mass and the convection of the dough in the dough mass continue without withstanding, and kneading proceeds. Other functions and effects are the same as those of the kneading element 120 of the first embodiment, and thus the description is omitted.

The projections 127 may be provided on either the top surface 123 or the side surface 122 of the kneading element 120, or may be provided on both. The number of projections is not limited. For example, in the modified example shown in FIG. 13, three protrusions 127 are provided. A member having a protrusion 127 may be provided on at least one of the top surface 123 and the side surface 122. In the modification shown in FIG. 14, a member having a projection 127 on the side surface 122 is provided. Such a member may be provided on either the top surface 123 or the side surface 122, or may be provided on both. In this case, it is preferable to form the member into a shape that forms a part of the kneading element 120. FIG. 15 shows a kneading element 120 of the seventh embodiment. The kneading element 120 is further provided with a stripping member 128 extending from the side surface 122 toward the peripheral wall 112 of the container 110. The stripping member 128 may be fixed to the kneading element 120, or may be detachably provided to the kneading element 120 by screwing or the like. The stripping member 128 may be formed of a material having high rigidity, or may be formed of a material which is easily elastically deformed. Further, in this embodiment, the front surface 128a, which is the front surface in the rotational direction of the cutting member 128, is higher than the virtual surface rising perpendicular to the bottom wall 111 of the container 110. It is falling backward and has a rake. However, the present invention also includes an embodiment in which the front face 128a rises perpendicularly to the bottom wall 111 so that no rake angle is provided, as shown in a modified example of FIG. In. The function of the projection 127 will be described.

When the kneading element 120 rotates in the container 110, the material and the dough are moved upward by the side surface 122 while moving to the container peripheral wall 112, and dropped by gravity. The material may remain between the portion of the side face 122 of the child 120 that is farthest from the rotation center axis 121 and the peripheral wall 112 of the container, and may not easily be taken into the dough mass. This takes too long to finish kneading the dough mass. This is likely to occur, for example, when using materials with low moisture. Moreover, when the container 110 and the kneading element 120 are variously combined, it is likely to occur when the kneading element 120 having a smaller radius than the peripheral wall 112 of the container is combined. With the use of the kneading element 120 of the seventh embodiment, the stripping member 1 28 closes the gap between the side wall 122 of the kneading element 120 and the peripheral wall 112 of the container 110. The material between the kneading element 1 20 and the container peripheral wall 1 1 2 is removed to give an opportunity to be taken into the dough mass. As a result, even if the material is difficult to be incorporated into the dough mass, the material can be smoothly incorporated into the dough mass and kneading can be completed quickly. In addition, container 110 and kneading element 120 are assigned. Even if a relatively large gap is created between the kneading element 120 and the container peripheral wall 112, the kneading can be performed well by attaching the removing member 128. And the common use of parts is progressing. Other functions and effects are the same as those of the kneading element 120 of the first embodiment, and thus the description thereof is omitted. The present invention includes all embodiments in which the features of each embodiment described above are combined. To give a few examples, in the kneading element 120 of the second embodiment, the side face is formed so as to be stepped when sectioned along a plane including the rotation center axis. At least one of the embodiments includes an uneven surface. Further, in the kneading element 120 of the third embodiment, when the side face is cross-sectioned at a plane perpendicular to the rotation center axis, the distance from one point on the side face to the rotation center axis corresponds to the Fibonacci sequence. Example in which the first and second rounds of a line formed by connecting the quarter circles of a plurality of circles in tangent to each other in tangent order, the side, and the top surface At least one of them includes an embodiment in which irregularities are formed. Further, in the kneading element 120 of the fourth embodiment or the fifth embodiment, when the side face is cross-sectioned at a plane perpendicular to the rotation center axis, the distance from one point on the side face to the rotation center axis is smaller. It is formed by a line of one round after the second round of the line that connects the quarter circles of multiple circles whose radius increases in accordance with the Fibonacci sequence in tangent order. The embodiments include an embodiment in which the side surface is formed to have a stepped shape when sectioned along a plane including the rotation center axis. Further, these embodiments include an embodiment in which a protrusion is further provided, and an embodiment in which a stripping member is further provided in these embodiments. According to the above description of the embodiment, the first embodiment in which the container having the bottom wall and the peripheral wall rising from the peripheral edge of the bottom wall and the rotation center axis is arranged to rise from the center of the bottom wall in the container. A kneading device including the kneading element of Example 7 and a rotation driving means for rotating at least one of the kneading element and the container is also fully disclosed, By the description of these examples, the kneading element of the first kneading device of the present invention described in the section of “Disclosure of the invention” above can be sufficiently disclosed. Further, according to the description of these examples, the kneading elements of the second to ninth kneading apparatuses described below and the kneading apparatus including these kneading elements have been sufficiently described.

That is, in the kneading element of the first kneading apparatus, the side face of the kneading element of the second kneading apparatus is formed so as to form a logarithmic spiral when cross-sectioned along a plane perpendicular to the rotation center axis. ing.

By doing so, the distance from one point on the side surface of the kneading element to the rotation center axis increases smoothly without any discontinuity in one rotation, so the kneading of the first kneading device The kneading element of the third kneading apparatus is preferable as the side shape of the kneading element that obtains the action of the element. The side face of the kneading element of the first kneading apparatus is a cross section at a plane perpendicular to the rotation center axis. Then, the distance from one point on the side surface to the center axis of rotation is two laps of a line that connects the quarter laps of multiple circles whose radius increases in accordance with the Fibonacci sequence in tangent order. It is formed by a line for one round after the eye.

In this way, a line approximating a conformal spiral having a spiral orbit using the golden ratio of the logarithmic spiral is obtained. As a result, the distance from one point on the side surface of the kneading element to the rotation center axis increases smoothly without any discontinuity during one rotation, and the kneading element of the first kneading device is used. It is preferable for the side shape of the kneading element to obtain the effect of the above. In this case, a spiral approximation line can be obtained by combining the circles, so that the kneading element can be easily manufactured.
