Description

The present invention relates to a stirring and crushing treatment device.

Rice is a very nutritious food. In Japan, where the food self-sufficiency rate is low, the self-sufficiency rate is virtually 100%. On the other hand, the spread of foods made mainly of wheat such as bread and noodles has caused a surplus of rice. Therefore, for the purpose of further expanding the use of rice, it has been attempted to produce bread, noodles, etc., which are mainly made of rice raw materials such as rice flour, as an alternative raw material for wheat flour (for example, see Patent Document 1).

JP, 2013-236693, A

Patent Document 1 describes a crushing container (“container” in Patent Document 1) capable of containing an object to be processed (“raw rice” in Patent Document 1), and an object to be processed provided in an internal space of the crushing container. An agitating and pulverizing apparatus (Patent Document 1), which includes a blade portion (a "cutting and kneading means" in Patent Document 1) for agitating and pulverizing, and a pulverizing rotary shaft (a "rotating shaft" in Patent Document 1) for rotationally driving the blade portion. 1 discloses the configuration of an "automatic bread maker").

In the stirring and crushing treatment device described in Patent Document 1, the crushing container is formed in a bowl shape that opens upward. The crushing rotary shaft is provided so as to penetrate the bottom of the crushing container and extend upward. The blade part is fixed to the crushing rotary shaft and is located near the bottom of the crushing container in the internal space of the crushing container.

The stirring and pulverizing apparatus described in Patent Document 1 does not include a scraper that removes the object to be treated attached to the inner wall of the pulverizing container. Here, in the case of adding a scraper to the stirring and pulverizing apparatus described in Patent Document 1, by extending the crushing rotary shaft upward and fixing the scraper to the extended part by using the extended part as the scraper rotary shaft. It is conceivable to adopt a configuration in which the blade portion and the scraper rotate integrally. With this configuration, by appropriately designing the shape of the scraper, the object to be treated attached to the inner wall of the crushing container can be removed by the rotating scraper.

However, since the crushing rotary shaft is cantilevered, when the crushing rotary shaft is extended, the vibration generated when the crushing rotary shaft rotates increases, and a large noise may occur.

It is an object of the present invention to provide an agitating and pulverizing treatment apparatus which is equipped with a scraper and which can avoid a situation in which vibration generated when the pulverizing rotary shaft rotates becomes large.

The features of the stirring and pulverizing apparatus according to the present invention are:
A crushing container capable of containing an object to be processed,
A blade part provided in the internal space of the crushing container and stirring and crushing the object to be treated,
A crushing rotary shaft that drives the blade to rotate,
A scraper that is provided in the internal space of the crushing container and removes the object to be processed attached to the inner wall of the crushing container;
A scraper rotating shaft for rotating the scraper,
It said pulverizing rotary shaft, and said scraper rotary shaft, the Ri separate der,
A blade drive motor for supplying rotational power to the crushing rotary shaft,
A motor connecting member is separably connected to the bottom of the crushing container, and the blade drive motor is separably connected to a lower portion of the motor connecting member,
The output shaft of the blade drive motor and the crushing rotary shaft are separate bodies, and the output shaft of the blade drive motor projects upward from the blade drive motor into the internal space of the motor connecting member, and A rotating shaft projects downward from the bottom of the crushing container into the internal space of the motor connecting member, and in the internal space of the motor connecting member, the output shaft of the blade drive motor and the crushing rotating shaft are coupled by a coupling mechanism. It is connected to each other .

According to the present invention, the crushing rotary shaft and the scraper rotary shaft are separate bodies. Then, the scraper can be attached to the scraper rotating shaft. Therefore, it is not necessary to extend the crushing rotary shaft to attach the scraper. As a result, the crushing rotary shaft can be formed shorter than the configuration in which the scraper is fixed to the extension of the crushing rotary shaft.

Therefore, according to the present invention, it is possible to avoid a situation in which the vibration generated when the crushing rotary shaft rotates becomes large even though the scraper is provided.

Furthermore, in the present invention,
The crushing container has a bowl-shaped container body that opens upward, and a lid portion that covers an opening portion of the container body,
The crushing rotary shaft is provided in a state of being supported by the container body and extending upward.
It is preferable that the scraper rotation shaft is provided in a state of being supported by the lid and extending downward.

With this configuration, when the user puts the object to be processed into the crushing container, the user can open the lid and put the object into the bowl-shaped container body. As a result, the object to be treated is accumulated at the bottom of the bowl-shaped container body. Further, according to this configuration, the scraper is located above the internal space of the crushing container, and the blade portion is located below the internal space of the crushing container.

Therefore, the blade portion easily comes into contact with the object to be treated accumulated on the bottom portion of the bowl-shaped container body. Further, the object to be treated removed from the inner wall of the crushing container by the scraper falls and is agitated and pulverized by the blade portion located on the lower side. Therefore, the object to be processed can be efficiently stirred and pulverized.

Furthermore, in the present invention,
It is preferable that the dividing line between the container body and the lid is located between the upper end of the crushing rotary shaft and the lower end of the scraper rotary shaft in the vertical direction.

According to this configuration, the crushing rotary shaft becomes shorter than when the upper end of the crushing rotary shaft is located above the dividing line. Further, the scraper rotation shaft becomes shorter than in the case where the lower end of the scraper rotation shaft is located below the dividing line.

Therefore, according to this configuration, it becomes easy to avoid a situation in which vibration generated when the crushing rotary shaft and the scraper rotary shaft rotate becomes large.

Furthermore, in the present invention,
A bearing holder is formed inside the motor connecting member between the bottom portion of the crushing container and the coupling mechanism, and a blade bearing rotatably supporting the crushing rotary shaft is held by the bearing holder. Is preferable.

According to this structure, the crushing rotary shaft is supported by the blade bearing, so that the crushing rotary shaft is stabilized. Therefore, as compared with the case where the blade bearing is not provided, it is possible to suppress the vibration generated when the crushing rotary shaft rotates.

Furthermore, in the present invention,
The crushing container has a bowl-shaped container body that opens upward, and a lid portion that covers an opening portion of the container body,
The crushing rotary shaft is supported on the bottom of the container body,
It is preferable to include a stirring blade that is located between the bottom portion of the container body and the blade portion in the vertical direction and that rotates integrally with the grinding rotation shaft.

There is a possibility that the object to be treated may stay between the blade portion and the bottom portion. Then, when the object to be processed stays, the object to be processed staying is unlikely to come into contact with the blade portion, so it is assumed that the stirring and pulverizing process becomes insufficient.

Here, according to the above configuration, since the stirring blade is provided between the blade portion and the bottom portion, it becomes difficult for the object to be treated to stay. Therefore, it is possible to avoid the situation where the stirring and pulverizing process becomes insufficient.

Further, the features of the attachment/detachment jig for attaching/detaching the blade portion in the stirring and pulverizing apparatus according to the present invention are:
The crushing container has a bowl-shaped container body that opens upward, and a lid portion that covers an opening portion of the container body,
On one end side in the longitudinal direction, a fitting portion that fits into a fitted portion of a mounting member for mounting the blade portion on the crushing rotary shaft is provided,
The length from the other end in the longitudinal direction to the fitting portion is longer than the depth from the dividing line between the container body and the lid portion to the fitted portion.

In the attachment/detachment jig, the fitting part is provided on one end side in the longitudinal direction, and if the length from the other end in the longitudinal direction to the fitting part is relatively short, the fitting part is set as the fitted part. When fitted, the position of the end of the attachment/detachment jig on the side opposite to the fitting portion is likely to be lower than the opening of the container body. As a result, the user has to reach into the opening of the container body to hold the end. Then, since the attachment/detachment work is performed with the hand in the opening of the container body, the attachment/detachment work tends to be difficult.

According to the above configuration, when the fitting portion is fitted to the fitted portion, the end of the attachment/detachment jig on the side opposite to the fitting portion is located above the opening of the container body. It will be in a state of protruding. Therefore, the user does not need to put his/her hand into the opening of the container body, and the attachment/detachment work can be easily performed.

It is a front view which shows the whole stirring pulverization processing apparatus. It is a side view which shows the whole stirring pulverization processing apparatus. It is a top view which shows the whole stirring pulverization processing apparatus. It is sectional drawing which shows the structure of a scraper and a blade part periphery. It is a figure which shows the structure of the attachment/detachment jig. It is a figure which shows the attachment/detachment jig in the state which the 1st fitting part fitted in the 1st fitted part, and the 2nd fitting part was fitted in the 2nd fitted part.

These may be used alone or in combination. Furthermore, the material to be treated is not particularly limited, but may include, for example, water, salt, saccharides, a thickener, an oil and fat component, and the like.

Further, as shown in FIG. 1, the processing apparatus main body 5 includes a container swinging mechanism 7. The container swinging mechanism 7 includes a container swinging shaft 71, a pair of left and right swinging shaft support members 72, a container swinging motor 73, a container swinging switch 74, and a container returning switch 75. .. The container swing switch 74 and the container return switch 75 are electrically connected to the container swing motor 73. The container swinging motor 73 has a speed reducing mechanism inside and is configured to rotate the container swinging shaft 71 at a low speed.

The container swing shaft 71 is provided so as to extend in the left-right direction. The pair of left and right swing shaft support members 72 are provided so as to extend in the vertical direction, and their lower ends are supported by the base frame 2. The container swing shaft 71 is supported by the upper ends of the pair of left and right swing shaft support members 72.

Further, as shown in FIG. 1, a motor connecting member 81 is attached to the lower end of the container body 61. A blade drive motor 82 is attached to the lower end of the motor connection member 81.

The motor connection member 81 is fixed to the container swing shaft 71. When the user steps on the container swing switch 74, the container swing motor 73 causes the container swing shaft 71 to rotate at a low speed. As a result, as shown by the phantom line in FIG. 2, the crushing container 6, the motor connecting member 81, and the blade drive motor 82 integrally swing with the container swing shaft 71 as the swing axis. As a result, the posture of the crushing container 6 changes from the vertical posture shown by the solid line in FIG. 2 to the sideways posture shown by the phantom line. That is, with this configuration, the user can tilt the crushing container 6 toward you. As a result, the user can easily insert and remove the object to be processed.

Further, when the user steps on the container return switch 75, the container swinging motor 73 causes the container swinging shaft 71 to rotate at a low speed. At this time, the container swing shaft 71 rotates the crushing container 6 in a direction to return the crushing container 6 from the sideways tilted posture to the vertical posture. As a result, the user can easily return the posture of the crushing container 6 to the vertical posture.

Further, as shown in FIGS. 1 to 3, the lid 62 is provided with an additive injection device 10. The additive injection device 10 has an additive tank 11 and an additive valve 12. The additive tank 11 is configured to be able to store the additive. The additive valve 12 is electrically connected to the control panel 3.

The user can put the additive in the additive tank 11. Then, the additive feeding device 10 feeds the additive stored in the additive tank 11 into the internal space of the crushing container 6. The additive amount of the additive is adjusted by the additive valve 12. The user can control the operation of the additive valve 12 by operating the control panel 3.

Further, as shown in FIG. 1, a blade portion 21 and a scraper 31 are provided in the internal space of the crushing container 6. By rotating, the blade part 21 stirs and grinds the object to be treated put into the internal space of the grinding container 6. The scraper 31 rotates to scrape off the object to be processed attached to the inner wall of the crushing container 6. Thereby, the scraper 31 removes the object to be processed attached to the inner wall of the crushing container 6.

As described above, the stirring and crushing processing apparatus 1 is provided in the inner space of the crushing container 6 and is provided with the blade portion 21 for stirring and crushing the object to be processed and the inner wall of the crushing container 6 provided in the inner space of the crushing container 6. And a scraper 31 for removing the processed object.

Further, as shown in FIGS. 1 to 3, the vacuum pump 4 is connected to the lid portion 62 via the suction pipe 41. Then, the vacuum pump 4 sucks the air in the internal space of the crushing container 6 via the suction pipe 41. With this configuration, the vacuum pump 4 can reduce the pressure inside the crushing container 6.

The vacuum pump 4 may be directly attached to the lid 62 without providing the suction pipe 41. However, as shown in FIG. 1 to FIG. 3, the vacuum pump 4 and the lid portion 62 are separately arranged and separated from each other, and the vacuum pump 4 and the lid portion 62 are connected via the suction pipe 41. With such a configuration, even if the object to be processed is scattered by the rotation of the blade portion 21 in the internal space of the crushing container 6, the suction pipe 41 is interposed between the crushing container 6 and the vacuum pump 4. Therefore, it becomes difficult for the object to be processed to reach the vacuum pump 4. Therefore, it becomes easy to avoid the situation where the object to be processed enters the vacuum pump 4.

Further, the stirring and pulverizing apparatus 1 is equipped with a vacuum valve (not shown) and an open valve (not shown). Both the vacuum valve and the release valve are electrically connected to the control panel 3.

The vacuum valve is connected to the vacuum pump 4 and the crushing container 6. This vacuum valve is an automatic valve for transmitting the vacuum created by the vacuum pump 4 to the internal space of the crushing container 6.

The open valve is connected to the crushing container 6. This open valve is an automatic valve for returning the internal space of the crushing container 6 from the vacuum state to the atmospheric pressure. When this open valve is opened, the internal space of the crushing container 6 communicates with the atmosphere.

That is, the blade portion 21 is attached to the crushing rotary shaft 22 by the second bolt 23.

As shown in FIG. 4, a dividing line 64 between the container body 61 and the lid 62 is located between the upper end of the crushing rotary shaft 22 and the lower end of the scraper rotary shaft 32 in the vertical direction.

Further, the output shaft 82a of the blade drive motor 82 is provided so as to extend upward. The output shaft 82a is located in the internal space of the motor connecting member 81.

The output shaft 82a is a separate body from the crushing rotary shaft 22. The output shaft 82a and the crushing rotary shaft 22 are connected to each other by the coupling mechanism 83.

With this configuration, the rotational power of the blade drive motor 82 is transmitted to the crushing rotary shaft 22 via the output shaft 82a. Then, the blade portion 21 is rotationally driven by the rotational power transmitted to the crushing rotary shaft 22. That is, the crushing rotary shaft 22 drives the blade portion 21 to rotate.

As described above, the stirring and pulverizing apparatus 1 includes the pulverizing rotary shaft 22 that rotationally drives the blade portion 21. The stirring and crushing processing apparatus 1 also includes a blade drive motor 82 that supplies rotary power to the crushing rotary shaft 22. The output shaft 82a of the blade drive motor 82 and the crushing rotary shaft 22 are separate bodies and are connected to each other by a coupling mechanism 83.

A stirring blade 25 is fixed to the blade supporting portion 24. The stirring blade 25 is located between the bottom portion 61a of the container body 61 and the blade portion 21 in the vertical direction. Then, the stirring blade 25 rotates integrally with the crushing rotary shaft 22. The stirring blade 25 rotates to stir the object to be treated put into the internal space of the crushing container 6.

As described above, the stirring and pulverizing apparatus 1 includes the stirring blade 25 that is positioned between the bottom portion 61a of the container body 61 and the blade portion 21 in the vertical direction and that rotates integrally with the pulverizing rotary shaft 22.

The blade bearing 85 is located between the blade portion 21 and the coupling mechanism 83 in the vertical direction. Further, the blade bearing 85 rotatably supports the crushing rotary shaft 22.

As described above, the stirring and pulverizing apparatus 1 is provided with the blade bearing 85 that rotatably supports the pulverizing rotary shaft 22 between the blade portion 21 and the coupling mechanism 83 in the vertical direction.

With this configuration, the crushing rotary shaft 22 is supported by the bottom portion 61a of the container body 61 via the blade bearing 85, the bearing holding portion 84, and the motor connecting member 81. That is, the crushing rotary shaft 22 is supported by the bottom portion 61 a of the container body 61. The crushing rotary shaft 22 is supported by the container body 61 and is provided so as to extend upward.

The blade drive motor 82 is electrically connected to the control panel 3 shown in FIG. Then, the user can control the rotation of the blade portion 21 and the stirring blade 25 by operating the control panel 3.

According to the configuration described above, the crushing rotary shaft 22 and the scraper rotary shaft 32 are separate bodies. The scraper 31 is attached to the scraper rotation shaft 32. Therefore, it is not necessary to extend the crushing rotary shaft 22 in order to attach the scraper 31. As a result, the crushing rotary shaft 22 can be formed shorter than the configuration in which the scraper 31 is fixed to the extension of the crushing rotary shaft 22.

Therefore, according to the configuration described above, it is possible to avoid the situation in which the vibration generated when the crushing rotary shaft 22 rotates becomes large even though the scraper 31 is provided.

[Operation of stirring and crushing processing device]
Next, the operation of the stirring and pulverizing apparatus 1 will be described. In the following, as an example, description will be given according to the procedure of the operation of making brown rice into a paste. The operation of the stirring and crushing processing apparatus 1 described below is merely an example, and is not particularly limited to the following operation.

First, the user opens the lid portion 62 and puts the object to be treated containing brown rice and water after the water immersion treatment into the internal space of the crushing container 6. At this time, the user may oscillate the crushing container 6 with the container oscillating shaft 71 as the oscillating axis, and insert the object to be processed in a state in which the crushing container 6 is inclined toward you.

After loading the object to be processed, the user closes the lid portion 62, operates the lock tool 66 to fix the lid portion 62 in the closed state, and loads the additive into the additive tank 11. Then, the user operates the control panel 3 to set operating conditions. The operating conditions include the rotational speed and the rotational time of the blade portion 21 and the scraper 31, and the addition timing of the additive.

After setting the operating conditions, the user operates the control panel 3 to start the stirring and crushing process. When the stirring and crushing process is started, the internal space of the crushing container 6 is depressurized by the vacuum pump 4, and the blade portion 21, the stirring blade 25, and the scraper 31 are rotated, and the object to be processed is stirred and crushed. In addition, during the stirring and pulverizing process, the additive is introduced into the internal space of the crushing container 6 from the additive introducing device 10.

When the stirring and crushing process is completed, the pressure in the internal space of the crushing container 6 is automatically returned to the atmospheric pressure. Then, the user can open the lid 62 and take out the object to be processed that has been subjected to the stirring and crushing processing.

Through the above steps, brown rice is made into a paste.

A first fitting portion 16 a (corresponding to a “fitting portion” according to the present invention) is formed on the inner wall of the first holding portion 16.

The second member 17 has a second handle portion 17a, a second shaft portion 17b, and a second holding portion 18. The second handle portion 17a is a rod-shaped member. The second shaft portion 17b is a tubular member. The second handle portion 17a and the second shaft portion 17b have their longitudinal directions orthogonal to each other.

The central portion in the longitudinal direction of the second handle portion 17a is connected to one end of the second shaft portion 17b. Further, the second holding portion 18 is connected to the other end of the second shaft portion 17b.

The second holding portion 18 is a cup-shaped member. Then, the second holding portion 18 opens toward the side opposite to the side where the second shaft portion 17b is located with respect to the second holding portion 18. A second fitting portion 18 a is formed on the inner wall of the second holding portion 18.

Then, as shown in FIG. 5, in the attachment/detachment jig 14, the first shaft portion 15b is in a state of being inserted into the second shaft portion 17b. Then, the first member 15 and the second member 17 are relatively rotatable about the axis P of the first shaft portion 15b and the second shaft portion 17b.

As shown in FIG. 6, the second bolt 23 of the stirring and pulverizing apparatus 1 has a first fitted portion 23a (corresponding to the “fitted portion” according to the present invention). A second fitted portion 24a is formed on the upper end portion of the blade supporting portion 24 of the stirring and pulverizing apparatus 1. Then, the first fitting portion 16a fits into the first fitted portion 23a. Further, the second fitting portion 18a fits into the second fitted portion 24a.

Further, as shown in FIG. 6, the length X from the end on the side where the first handle portion 15a is located to the first fitting portion 16a in the longitudinal direction of the attachment/detachment jig 14 is determined by the container body 61 and the lid. It is longer than the depth Y from the dividing line 64 with the portion 62 to the first fitted portion 23a.

As described above, the attachment/detachment jig 14 has a first fitting portion that is fitted to the first fitted portion 23 a of the second bolt 23 for attaching the blade portion 21 to the crushing rotary shaft 22 at one end side in the longitudinal direction. The part 16a is provided. In addition, the attachment/detachment jig 14 has a length X from the other end in the longitudinal direction to the first fitting portion 16a from the dividing line 64 between the container body 61 and the lid portion 62 to the first fitted portion 23a. It is formed to be longer than the depth Y.

[How to use the attachment/detachment jig]
Hereinafter, a method of using the attachment/detachment jig 14 will be described. First, the user holds the first holding portion 15a with one of the two hands and holds the second holding portion 17a with the other hand. In this state, the user inserts the first holding portion 16 and the second holding portion 18 of the attachment/detachment jig 14 into the internal space of the crushing container 6 through the opening of the container body 61.

Then, as shown in FIG. 6, the user fits the first fitting portion 16a into the first fitted portion 23a and fits the second fitting portion 18a into the second fitted portion 24a. Let In this state, the user relatively rotates the first member 15 and the second member 17 about the axis P, so that the second bolt 23 receives a force in a direction of rotating about the axis P. At this time, since the blade support portion 24 is prevented from rotating by the second holding portion 18, the blade support portion 24 is prevented from rotating together.

At this time, the user can turn the first member 15 with respect to the second member 17 either clockwise or counterclockwise when viewed from above.
