2. Description of the Related Art In a domestic rice mill, an apparatus main body having a built-in drive mechanism for rotating a rotating shaft, a container integrally provided with the apparatus main body and having an open upper end, and a large number of separation machines are provided. With a hole, a bran chamber is formed between the inner surface of the container and a separation basket which is housed so as to be able to be taken in and out of the container, and is detachably attachable to the rotating shaft arranged at a central portion in the container. And a rotating tool mounted in the separating cage and rotated in the separating cage. According to this rice milling machine, the brown rice housed in the separation basket is stirred in the separation basket by rotation of the stirring tool, and the rice bran generated from the brown rice is passed through the separation hole of the separation basket while rubbing the rice together with the rice. It can be separated into rooms and brown rice can be polished. In this milling machine, the milling time is set by operating a push button in accordance with a milling degree table indicating the relationship between the amount of brown rice and the milling time described on the outer surface of the apparatus body or in an instruction manual.

[0003]

By the way, even with the same milling time, the amount of bran and the degree of milling vary depending on various conditions such as the location, type, storage period, and dryness of brown rice to be milled. The milling degree table is only a guide. For this reason, it is difficult to expect an appropriate rice milling according to the user's preference only by specifying the milling time depending only on the table, and the conventional rice milling machine is required to reduce the rice milling condition such as the condition of rice bran accumulation. Since the configuration cannot be easily known, there is a problem that it is difficult to finely adjust the milled rice according to the variation.

[0004] Further, as described above, the conventional rice milling machine cannot know the condition of rice bran accumulation and the like. Therefore, when a rice milling demonstration is performed at a store, the rice milling state cannot be visually recognized accurately. There is a problem.

An object of the present invention is to provide a grain processing apparatus capable of accurately knowing the condition of milled rice or the like.

In this grain processing apparatus, the separating basket is set in a container, and a bran chamber is formed between the separating basket and the container, and is located at the center of the set separating basket. A stirring tool is attached to the rotating shaft. When the container is integral with the apparatus main body, a suitable amount of grains such as brown rice is put into a separation basket, the container is closed with a lid, and then the drive mechanism of the apparatus main body is operated and used. If the container is separate from the device main body, attach this container to the device main body, put a suitable amount of grains such as brown rice into a separating basket before and after the container, close the container with a lid,
It is used by operating the drive mechanism of the apparatus main body. In this use, by the operation of the drive mechanism, the rotating shaft disposed in the center of the separating car and the stirring tool attached to this shaft,
It rotates in the stationary separation basket and stirs the grains such as brown rice already put in the separation basket, so that the bran of the grains passes through the many separation holes opened in the separation basket and the container. The rice bran is collected from the bottom side in the bran chamber between the and the separating basket, and the grains such as rice from which the bran has been removed remain in the separating basket.

According to a first aspect of the present invention, at least a part of the container is formed of a transparent material through which the lower part of the bran chamber can be seen.
At least a part of the lid is formed of a transparent material through which the inside of the separation cage can be seen.

According to the first aspect of the present invention, the bran chamber can be seen through the portion formed of the transparent material of the container as needed in the cereal grains such as the milled rice. In addition to being able to see the amount, and also to see the inside of the separation basket through the transparent material of the lid if necessary in the grain, the color of the grains in this basket,
That is, the degree of whitening can be visually recognized. In particular, since the amount of accumulated bran can be visually checked, even when the amount of refined rice is small, for example, 1 go or less, it is estimated from the amount of accumulated bran, 3 minutes, 5 minutes, and 7 minutes. It is also possible to know the situation of classification, such as spelling. Therefore, it is possible to accurately know the condition of the cereal grain by visually checking both the amount of the bran and the degree of milling, and also to use the condition of the cereal grain in the demonstration of the sale of the grain processing apparatus. It can be surely visually recognized.

[0010] In order to solve the same problem, the invention of claim 2 is characterized in that the entire container and the entire lid are formed of a transparent material.

According to the second aspect of the present invention, the amount of the bran accumulated in the bran chamber can be visually recognized through an optional portion of a container formed of a transparent material as required in the milled rice or the like. If necessary, the color of the grains in the separated basket, that is, the degree of milling, can be visually recognized through the portion of the lid formed of a transparent material that faces the inside of the separated basket. In particular, since the amount of accumulated bran can be visually checked, even when the amount of refined rice is small, for example, 1 go or less, it is estimated from the amount of accumulated bran, 3 minutes, 5 minutes, and 7 minutes. It is also possible to know the situation of classification, such as spelling. Therefore, it is possible to accurately know the condition of the cereal grain by visually checking both the amount of the bran and the degree of milling, and also to use the condition of the cereal grain in the demonstration of the sale of the grain processing apparatus. It can be surely visually recognized. Moreover, in the present invention, the position of the visual recognition is rarely limited at the time of the visual recognition. In particular, the visual recognition of the amount of bran does not have a direction, so that the grain condition can be more easily known.

And the back side of this part 53a (the center part side of the lid 51) is open.

The entire lid 51 is made of a material having high transparency, for example, AS (acrylonitrile / styrene resin) among synthetic resins, but transparent glass may be used instead. Note that the resin material having excellent transparency has extremely low elasticity due to its physical properties, and when used for applications that repeatedly undergo elastic deformation, has a high possibility of causing cracks in the elastically deformed portion and has low durability. Therefore, it is not suitable as a transparent material for forming the lid 51 integrally with the handle engaging body described below.

As shown in FIGS. 3, 7, and 8, a handle engaging body 52 is attached to the outer periphery of the lid 51 that is 180 ° away from the spout catching portion 53. This engagement body 5
Reference numeral 2 denotes a molded article made of a material having a high elasticity formed separately from the lid 51, for example, a synthetic resin such as POM (polyacetal), which is an opaque material because of exhibiting durable elasticity.

Further, the switch operation convex portion 54 of the lid 51 enters the opening 17a of the switch convex portion 17 of the apparatus main body 1 as shown in FIG. 2, and the safety switch (not shown) is held in the ON state.

After the above setting is completed, the rice milling switch, that is, the timer time of the timer switch 14 is set in accordance with the amount of brown rice put into the separating basket 31, so that the bran having a dry structure as described below is obtained. , Ie, milled rice (milled) or polished rice (milled).

That is, the drive mechanism 10 in the apparatus main body 1 is operated, and the rotation of the output shaft 8 is controlled by the couplings 9, 28.
Is transmitted to the rotation shaft 27 via the shaft 27, and the stirring tool 41 is rotated in the separation car 31 together with the shaft 27. The arrow in FIG. 6 indicates the rotation direction. Therefore, this stirring tool 41
By the material pushing surfaces 44a of the pair of blades 44, the rice in the separation basket 31 is extruded toward the cage peripheral wall 32a while receiving the rotational force. The brown rice in the separating basket 31 is stirred by the high-speed rotation of the stirring tool 41 in the separating basket 31, so that the brown rice in the separating basket 31 cannot pass through due to the centrifugal force caused by the rotating motion of the rice. Car peripheral wall 32 having a large number of separation holes 35
It rotates while being pressed against the inner peripheral surface of a.

In this case, the blade 44 is
1 has a shape, for example, an arc shape, which retreats in the rotation direction so as to gradually approach the inner peripheral surface of the car peripheral wall 32a of the separating cage 31 from the central portion to the outer peripheral portion. The rice can easily escape along the arcuate outer surface of the rice. Therefore, while the rice is in contact with the material extruding surface 44a of the blade 44 facing the car peripheral wall 32a of the separating car 31 to reduce the impact force of the rice and reduce the damage of the rice, the blade 44 causes the rice to be moved to the inner periphery of the car peripheral wall 32a. The rice is smoothly extruded toward the surface, whereby the rice can be stirred in the separating basket 31 while pressing the rice against the inner peripheral surface of the car peripheral wall 32a.

As described above, the rice which is rotated at a high speed with the rotation of the stirring tool 41 rotates while being pressed against the inner peripheral surface of the cage peripheral wall 32a of the stationary separation cage 31 by the action of the centrifugal force. After moving toward the upper side of the inner peripheral surface of the car peripheral wall 32a, the rice is moved toward the car bottom wall 32b at the center of the separation car 31 by gravity, so that the rice in the separation car 31 is vertically convected ( (Indicated by an arrow in FIG. 3).

By the rubbing of the brown rice with the stirring and the rubbing of the brown rice with the separating basket 31 and the stirring tool 41, the rice is first removed from which the bran layer of the brown rice is removed, followed by the subsequent polishing. The rice removal (polished rice) is performed on rice (white rice). At the same time, the centrifugal action on the generated bran acts in each of the separation holes 35 provided in the car peripheral wall 32a, and the bran passes through the separation hole 35 and is transferred to the bran chamber C between the basket peripheral wall 32a and the container 21. From this portion, the water is stored in the bran chamber C at the bottom of the container 21. Similarly, with regard to brown rice pushed and moved along the basket bottom wall 32b by the blade 44, bran can be separated from rice in a large number of separation holes 36 provided in the basket bottom wall 32b that prevent passage of rice. The bran separated through is stored in the bran chamber C at the bottom of the container 21. Then, with the separation of the rice bran, the rice from which the bran has been removed remains in the separation basket 31. In this case, in the rubbing between the brown rice and each of the surfaces 44a to 44c of the blade 44, the small convex portion provided on each of the surfaces 44a to 44c can efficiently rub the skin layer of the brown rice. As a result, the time required for dry processing of grains from polishing to completion of polishing can be shortened.

During the above-mentioned rice polishing, the condition of the rice polishing can be known if necessary. That is, since the entire container 21 in which the bran is stored is made of transparent glass, the amount of the bran stored in the bran chamber C can be visually recognized through an arbitrary portion of the container 21.
Similarly, the lid 51 facing the upper opening of the separation car 31 is entirely made of a transparent synthetic resin.
You can see the color of the rice inside, that is, the degree of whitening. In addition, since the accumulated amount of the bran separated as described above can be visually checked, even when the amount of milled rice is small, for example, 1 go or less, it is estimated from the accumulated amount of the bran, every 3 minutes, every 5 minutes. , 7 minutes and so on. In this case, for example, a bran amount mark corresponding to the above-mentioned division may be provided on the inner surface or the outer surface of the container 21 so that the state of the division or the like can be grasped more easily. or. In the present embodiment, the visual recognition position is rarely limited at the time of the visual recognition. In particular, the visual recognition of the amount of bran has no directionality, so that the visibility is excellent.

By visually checking both the amount of rice bran and the degree of milling, the user can accurately know the condition of the milled rice. By grasping such rice milling conditions, the user determines the rice milling time for variations in the amount of bran and the milling degree due to various conditions such as the production site, type, storage period, and dryness of the brown rice to be milled. By dialing the timer switch 14, the rice polishing time can be finely adjusted.

Moreover, since both the amount of rice bran and the degree of milling can be visually recognized as described above, even if a demonstration is conducted at a store in the sale of this rice milling machine, the prospective purchaser can accurately visually recognize the state of the milled rice. Therefore, the demonstration effect can be improved.

In addition, the milled or polished rice is separated into baskets 31.
The removal of the bran in the rice bran chamber C left inside may be performed by the following procedure. First, in a state where the lid 51 is removed from the upper end of the container 21 in the above-described procedure, the separating basket 31 is removed from the container 21 upward, and then the stirring tool 41 in the basket 31 is removed. An operation such as inverting 31 can be easily performed without being restricted to the container 21 and the apparatus main body 1 in a state unrelated to the container 21 and the apparatus main body 1, whereby the white rice in the separation basket 31 can be taken out. it can.

As described above, the separation basket 31 from the container 21
Is carried out in a state in which the stirring tool 41 is accommodated in the separation car 31. Therefore, since the center cylinder 33 of the separation car 31 is covered by the stirring tool 41,
Even if rice is abundant, the separation basket 31 is passed through the cylindrical portion 33.
The rice inside does not leak. In addition, the bran stored in the container 21 can be easily taken out of the container 21 without being disturbed by the separation cage 31 due to the removal of the separation cage 31 described above. Moreover, in the present embodiment, the container 2
Since the container 1 can be detached from the apparatus main body 1, the container 21 can be carried to the sink in an independent state without being restricted by the apparatus main body 1, and the removal of bran, the cleaning of the container 21 and the like can be easily performed.

In addition, in the rice mill of the present embodiment,
After the rice polishing with the removal of the bran, the rice can be washed (grain-washed) after the removal of the bran as described above. This washed rice is in container 2
1 After the white rice in the detached separating basket 31 is lightly wetted with water and drained, the separating basket 31 is set in the container 21 again, and the grain processing attachment is assembled by the above-described assembling procedure. The setting is performed on the apparatus main body 1.
In the operation in this case, the timer switch 14 is not used, and the rice washing switch 15 is momentarily pressed several times in accordance with the amount of white rice in the separation basket 31, and the drive motor 4 is intermittently operated. Thereby, the stirring tool 41 is stirred without excessively shaving the white rice, and the rice is washed. Then, after this, according to the removal procedure described above, the separation basket 31 is taken out together with the white rice, and the stirring basket 41 is removed from the inside of the separation basket 31 while the separation basket 31 is immersed in water in the sink, and the white rice is gently lightened. The rice washing operation is completed by rinsing.

According to the rice treatment as described above, the bran is separated from the rice in the polished or polished rice. Therefore, even when the rice is washed manually without using the rice washing operation using the rice mill, Also, when performing the rice washing operation using the rice milling machine, since the amount of bran contained in the rinsing water is extremely small, the rice absorbs the water containing the bran dissolved in the rice washing so that the rice becomes a rice bran odor. Can be suppressed. Therefore, rice can be cooked deliciously by the subsequent rice cooking.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the entire container and the lid are each formed of a transparent material, but instead, only a part may be formed of a transparent material, and the other portions may be formed of an opaque material. In this case, the lower part of the bran chamber may be made of a transparent material so that the lower part of the bran chamber can be seen through. And a transparent material extending vertically or obliquely from the lower end to the upper end of the peripheral wall. In addition, the lid may be implemented by providing a transparent material only on the entire portion facing the upper end opening of the separating car or only a part of the portion so that the inside of the separating car can be seen through.

Further, even if the grain processing attachment having the above configuration is attached to an existing food processor or a new food processor having a switch capable of switching the number of rotations of the drive motor between cooking and polishing, the above-described rice polishing and rice bran removal can be performed. In this case, the versatility of the food processor can be improved. In addition, the present invention is not limited to rice milling, and it is possible to carry out grain milling or grain milling in which grains other than rice are treated in the same manner as rice milling.

Further, the present invention can be applied to the following. That is, on the upper side of the container that is removably mounted on the container mounting portion of the apparatus main body, a rotation shaft that is rotated by the drive mechanism of the apparatus main body and that can move up and down is provided downward,
A stirring device is connected to this shaft, and a rotating shaft and a stirring device are inserted from above into a separating basket housed in a container so as to be freely taken in and out, and the container and the device main body are connected, and the driving mechanism is operated in this state. By doing so, the present invention can be applied to a grain processing apparatus that simultaneously removes grain and bran such as brown rice. In this case, it is not necessary to provide a rotating shaft in the container, and a structure in which the rotating shaft passes through the bottom wall of the separating cage is not required.

In the present invention, the container is not separate from the apparatus main body as in the above-described embodiment, and may be provided integrally so as not to be detached from the apparatus main body. Further, in the present invention, the stirring tool is only required to be able to stir the grains in the separation basket by convection in the vertical direction or the like, and the blade is not necessarily required. In the present invention, the rice washing switch employed in the above embodiment may be omitted.
