DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing wireless rice for polishing rice polished by a pressure type rice mill or commercially available rice to obtain non-washed rice and a small household non-washed rice machine.

[0002]

2. Description of the Related Art Brown rice obtained by dehulling rice hulls as a hull with a huller is polished by a rice mill to remove germ and bran layers, and is then polished and used for food. The brown rice is shown in FIG.
As shown in the figure, the sample consists of endosperm a, surrounding aleurone layer (sticky bran layer) b, germ c and bran layer d. By the way, a home-use circulating rice mill (see Japanese Patent Application Laid-Open No. 5-253501).
A paste layer remains on the surface of rice milled through a pressure-type rice mill or a commercially available milled rice such as a rice mill with a single pass or a rice mill (see JP-A-4-74539 and JP-A-5-49038). This lowers the taste and causes the smell of bran. Further, after several days from the milling, the aleurone layer is oxidized, deteriorating the quality of the rice from the surface. It is difficult to remove all of the aleurone layer without damaging the endosperm (starch layer) inside it with current rice milling technology. Therefore, immediately before cooking the rice, the rice is ground with water and the aleurone layer and oxide film are removed. Has been removed. However, sharpening rice is quite time-consuming,
It is difficult to adjust the sharpness, and there is a problem of polluting the sewage environment by discarding starch that is easily soluble in water as sharpening juice. This sharpening juice is a major source of pollution in domestic wastewater.

[0003] On the other hand, a stirred rice mill is known as a kind of household rice mill. As shown in FIG. 7, for example, as shown in FIG. 7, a rice bran container 2, a rice milling basket 3 inside the case 1, and a stirring blade member 4 inside the rice mill 2 are arranged on the rice milling machine. And these can be separated as shown in FIG. The milled rice basket 3 has a net cage shape (net basket-shaped portion 3a) except for the central portion of the bottom surface and the upper end portion of the side surface, and the rotating shaft 3c is rotatable at the central portion of the bottom surface via a bearing portion 3b. Supported, the rotating shaft 3c
Below the joint 3d which receives the driving force of the motor described later
Has been fixed. In addition, 3e is a handle for suspension. The blade member 4 includes a rotating blade 4a and a supporting member 4b thereof, and a hole formed at the center of the supporting member 4b is
c and rotates together with the rotating shaft 3c. A motor 6 is installed at the bottom of the case 1,
A joint 7 detachably engaged with the coupling 3d is fixed to the tip of the rotating shaft.

In this stirring type rice mill, a bran container 2, a rice mill 3 and a blade member 4 are set in a case 1 as shown in FIG. 7, a required amount of brown rice is put in, and the opening is covered with a cover member 5. After that, when the motor 6 is driven, the blade member 4 rotates at a high speed, the rice is vigorously stirred by the rotating blades 4a, and the germ and the bran layer are mainly scraped off by the friction between the rice due to the high speed stirring, thereby polishing the rice. The bran produced by the above-mentioned process passes through the mesh of the mesh basket-shaped portion 3a and falls into the bran container 2. The degree of rice polishing can be set in advance by a timer, but if the lid member 5 is made of a transparent material, the state of the rice polishing can be seen from above, so that the motor may be stopped at the stage of appropriately polishing. When the rice polishing is completed, the lid member 5 is removed, the bran container 2 is extracted from the case 1, the rice mill 3 is extracted therefrom, the blade member 4 is extracted from the rotating shaft 3c, and the rice milled from the rice mill 3 is removed. And throw away the bran from the bran container 2 or open it in another container. Incidentally, such a stirring rice mill is disclosed in Japanese Patent Application Laid-Open No. 11-1975.
No. 21.

SUMMARY OF THE INVENTION This stirring type rice mill is
Compared to a conventional pressure-type rice mill, it has the advantage of being small in size and suitable for a small amount of rice, and can be used to mill any type of rice. However, when brown rice is polished using this agitated rice mill, the following problems have been found. That is,
In brown rice, paddy, immature rice, discolored rice, etc. are often mixed (a certain percentage is allowed by regulations), and when this is polished with a circulation rice mill or a single pass rice mill, the rice is removed. Then, the rice husks are discharged together with the bran, and the unripe rice and the colored rice are fragile and are also discharged together with the bran. However, if brown rice is polished with a stirring rice mill, the paddy will remain as it is, and unripe rice and discolored rice will remain in the polished rice basket without shattering, so that paddy, immature rice, discolored rice will be mixed in the polished rice . Such rice cannot be favored by consumers, and therefore, as a practical matter, it has to be said that this stirred rice mill is not suitable as a rice mill.

On the other hand, in the process of studying the performance of the stirring rice milling machine, the stirring rice milling machine, in addition to the above-mentioned advantages, has a good quality of cutting rice bran (branches separated from rice are well discharged,
It is possible to obtain rice with less adhesion of rice bran powder), and it is also possible to remove the aleurone layer and to make the rice grain surface glossy and smooth. Utilizing this characteristic of a stirring rice mill, it is possible to produce so-called non-washed rice in which rice can be cooked without grinding with water. In addition, this characteristic does not exist in the conventional pressure type rice mill. However, since agitated rice mills are not suitable as rice mills, after all, ordinary consumers have to use rice milled through a pressure rice mill or commercially available rice mills and have to grind with water before cooking rice. Also, a large amount of sharpening juice is continuously discharged. In addition, by this work to sharpen with water,
About 4% of the milled rice weight is lost.

SUMMARY OF THE INVENTION The present invention has been made to solve this problem, and it is possible to grind water at home by using a home-use circulating rice mill, a rice mill passed through a single-pass rice mill, or a purchased commercial rice mill. To remove the remaining adhering starch layer to provide delicious rice without reducing the labor and promote the modernization of kitchen life, and at the same time to eliminate the discharge of sharpening juice. Aim.

[0008]

Means for Solving the Problems Now, the stirring type rice mill has a fatal drawback that paddy, immature rice and discolored rice cannot be eliminated. However, a pressure-type circulation type rice mill or a single-pass rice mill is required. Passed and commercially available rice does not include paddy, immature rice, or discolored rice. Therefore, when limited to the use of removing the size layer of such milled rice, that is, when used as a rice-free rice washing machine, the above-mentioned drawback does not become a problem at all, and it is possible to take advantage of only the above-mentioned advantages of the stirring rice milling machine. it can. The present invention has been made focusing on this point.

[0009] The method for producing non-washed rice according to the present invention comprises a hopper having a bran removing portion formed in a part or all of the circumference in a porous direction, and a rotator which is rotated horizontally at the bottom to agitate the polished rice. A method for producing non-washed rice using a stirring type rice-free rice washing machine provided with members, put rice milled or commercially available rice milled with a pressure rice milling machine into the hopper, agitate with the stirring member to grind rice, It is characterized by obtaining unwashed rice. Further, the household stirring type rice-free rice washing machine according to the present invention is a rice-free rice washing machine that obtains rice-free washing by polishing rice milled by a pressure rice milling machine or commercially available rice-milling, and a hopper and a bottom portion for storing the rice polishing. With a stirring member that rotates in the horizontal direction and stirs the milled rice,
The hopper is characterized in that it comprises a bran removing part formed in a part or the whole in the circumferential direction. Alternatively, the household stirring type rice-free rice washing machine according to the present invention is a rice-free rice washing machine that obtains non-washed rice by polishing milled rice or commercially available milled rice with a pressure rice mill, and a hopper and a bottom portion for storing the milled rice. The hopper is provided with a stirring member that rotates in the horizontal direction to stir the milled rice, and the hopper includes a bran removing portion formed in a part in the circumferential direction, a white rice discharge opening, and an openable and closable white rice discharge door. Features.

[0010] In the above home-use stirring-type rice-free rice washing machine, a bran container is detachably provided outside the bran removing section of the hopper. If necessary, a storage device (so-called measuring rice bin) capable of storing and weighing and discharging a desired amount of milled rice is installed on the upper portion of the hopper, the rotation speed of the stirring member is made variable, and A white rice container can be detachably provided outside the white rice discharge door. Further, in the rice-free rice washing machine, the inside of the bran container may be depressurized, and the bran may be sucked from the hopper into the bran container and forcibly discharged.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to FIGS. FIG. 1 and FIG. 2 show an example of a stirring type non-washing rice machine according to the present invention, in which a hopper 12 for accommodating milled rice in a case 11 and a blade member 13 for stirring are arranged inside thereof. A lid member 14 covers the top,
The hopper 12 includes a bran removing portion 12a formed in a part in the circumferential direction, and a white rice discharge opening 12b and an openable and closable white rice discharge door 12c in another part in the circumferential direction.
A rice bran container 15 having an opening covering the rice bran removing portion 12a is provided on the outside of the rice removing portion 12a of the hopper 12 in a detachable (removable and retrievable manner from a lateral direction (see arrow)). A white rice container 16 having an opening covering the white rice discharge opening 12b is detachably provided (can be taken in and out from the lateral direction (see arrow)). Furthermore, case 11
A motor 17 is installed at the lower part of the
Bearing 1 is installed at the center of the bottom of hopper 12
The blade member 13 is supported by 2d and protrudes into the hopper 12, into which the blade member 13 is detachably attached, and rotates together with the rotating shaft 17a.

The bran removing portion 12a of the hopper 12 is provided from the outer peripheral portion of the bottom surface to the lower half portion of the side surface in a part of the hopper in the circumferential direction (range indicated by an arrow in FIG. 2). The bran removing portion 12a has, for example, a long hole (for example, 1 mm ×
(Approximately 12 mm). The polished rice discharge opening 12b is provided at the bottom of the hopper (from the bottom to the side in this example) at a position circumferentially separated from the bran removing portion 12a, and the polished rice discharge door 12c is provided inside the polished rice discharge opening 12b. The opening and closing mechanism (not shown) using, for example, an electromagnet allows the shutter to open and close in the direction of the arrow (see the solid line and the virtual line in FIG. 1).

In this agitated rice-free rice washing machine, a required amount of rice is put into a hopper 12, and the opening is covered with a lid member 14.
When the motor 17 is driven, the blade member 13 rotates at high speed, and the rotary blade 13a stirs rice at high speed. This high-speed stirring causes the rice to collide with each other and remove the aleurone layer from the polished rice, and the generated bran falls into the bran container 15 below through the holes in the bran removing section 12a. The rice polishing time is preset by a timer, for example, and if the opening and closing mechanism of the white rice discharge door 12b is activated shortly before the set time is reached,
White rice discharge door 12c while blade member 13 is still rotating
Automatically opens, the white rice falls into the white rice container 16 through the white rice discharge opening 12b by the stirring force of the rotating blades 13a,
When the set time has been reached, the opening / closing mechanism operates in reverse to close the white rice discharge door 12c.

After the polishing, the white rice container 16 is removed from the case 11 sideways, the white rice in the container is transferred to another container, and then the rice is simply returned. On the other hand, when the rice bran 15 is full of rice bran after a plurality of times of polishing rice, or at an appropriate time, the rice bran may be extracted laterally from the case 11 to discharge the rice bran. Thus, in the above-mentioned stirring type rice-free rice washing machine, the hopper 1
There is no need to touch or remove the blade 2 or the blade member 13, and the operation of removing the bran from the bran container 15 does not necessarily need to be performed every time. Moreover, the rice-free rice washing machine itself can be made compact.

In this rice washing machine, the blade member 1
It is desirable that the rotation speed of No. 3 be variable. Specifically, it is conceivable that the rotation speed can be selected, or that the rotation speed is automatically reduced in the middle of the set time.
In the latter case, for example, it is preferable that the rotation speed is initially high, and after a certain period of time, the rotation speed is automatically switched to low speed.
At this time, the rotation speed may be changed twice or more, or may be changed continuously. The reason why the rotation speed is made variable is that high-speed rotation is desirable in order to quickly remove the aleurone layer, and low-speed rotation is more desirable in order to make the surface of the rice grain glossy and smooth. In addition, low-speed rotation is also advantageous for improving rice bran and obtaining rice with less adhesion of rice flour. In low-speed rotation, the removal of the bran layer becomes sharply slow, so if, for example, it is switched from high-speed rotation to low-speed rotation when approaching the planned polishing level, the rice grain surface is smoothed after switching, Further, since the bran can be discharged from the holes of the bran removing portion 12a in the same manner as before without generating new bran, there is almost no adhesion of bran, and white rice having a glossy smooth surface can be obtained. Obtainable.

FIG. 3 shows another example of the stirring type riceless rice washing machine according to the present invention. The major difference from the stirred riceless washing machine shown in FIG. 1 is that the white rice container is not provided in the case 21,
The point is that the pressure inside the bran container 25 is reduced, and the bran is sucked into the bran container 25 from the hopper 22. More specifically, the difference between the structure and the effect is shown.
It looks like this: The white rice discharge door 22c of the hopper 22 is rotated about the upper end by an opening / closing mechanism (not shown) (solid line and virtual line), and a flow plate 26 is installed below the white rice discharge opening 22b. When the white rice discharge door 22c is opened, the white rice flows through the flow plate 26 into the container placed below. Since the white rice container is not provided in the case 21, the structure is simplified, the amount of rice polishing is not limited to the volume of the white rice container, and the bran container 2 is not used.
The space occupied by 5 can be widened.

A number of small holes 24a, 25a are formed in the bottom surface of the lid member 24 and the bran container 25, a fan 28 is disposed below the bran container 25, and a hole 21a is also formed in the case 21. When the fan 28 is operated, the inside of the bran container 25 is decompressed, and the hopper 2 is
2, a hole in the bottom of the bran container 25
a, a flow of air passing through the hole 21a of the fan 21 and the case 21 occurs (see the arrow), and the bran adhering to the hole of the bran removing portion 22a and the inner wall of the hopper 22 is actively sucked into the bran container 25. Therefore, the separation of the white rice and the bran is promoted, and the adhesion of the bran to the holes of the bran removing portion 22a and the inner wall of the hopper 22 is reduced. Although not particularly limited, the fan 28 is preferably set to operate and stop simultaneously with the blade member 23, and the power can be taken from the motor 27. In addition, in order to prevent the scattering of the bran, as illustrated in FIG.
It is desirable to install the filter 29 so as to cover at least the hole 25 a, or to install a bag-shaped filter inside the bran container 25 for use, for example, in a vacuum cleaner.

A pulley 31 is provided near the upper end of a rotating shaft 27a of the motor 27, and a pulley 33 is provided at a lower end of the rotating shaft 32 of the blade member 23, and these are connected by a belt 34 to transfer the power of the motor 27 to the blade member 23. To communicate. This structure is to take up space for the fan 28 and is merely ancillary.

Another example of the stirring type riceless rice washing machine according to the present invention is shown in FIGS. The major difference from the stirred riceless rice washing machine shown in FIG. 1 is that the white rice container is not disposed in the case 41 and the white rice discharge opening 42b of the hopper 42 overlaps with the bran removing portion 42a in the circumferential direction of the hopper. This is a point provided at the position. More specifically, the difference between the structure and the difference in operation and effect will be described below. The white rice discharge door 42c of the hopper 42 is rotated about the upper end by an opening / closing mechanism (not shown) (solid line and virtual line), and a flow plate 46 is installed below the white rice discharge opening 42b. When the white rice discharge door 42c is opened, the white rice flows through the flow plate 46 into the container placed below.

A porcelain removing portion 42a is formed in a part of the hopper 42 in the circumferential direction, and a white rice discharge opening 42b is formed in an overlapping position in the circumferential direction.
Outside the bran removing section 42a of the hopper 42, the bran removing section 42a
A bran container 45 having an opening for covering the bran is provided in a horizontally detachable manner. The bran container 45 is cut into circumferentially inner and outer side walls so as to be detachable without interfering with the flow plate 46. Notches 46a and 46b are formed. Bran removal part 4
By setting the 2a and the white rice discharge opening 42b at positions overlapping in the circumferential direction, the white rice and the bran can be taken out in the same direction (forward).

FIG. 6 shows another example of the stirring type riceless rice washing machine according to the present invention. The difference from the conventional agitated rice-free rice washing machine (particularly those shown in FIGS. 4 and 5) is that a storage device 53 for storing and measuring and discharging the polished rice above the hopper 52 is provided. The storage device 53 includes a rice storage hopper 54 and a measuring chamber 55 connected to a lower end thereof. In the measuring chamber 56, a measuring rotating body 56 in which three radial fins 56b are formed at equal angles around an axis 56a is arranged, and by rotating the knob 57, a fixed amount is turned every １ ／ rotation. The rice is released downward. By arranging such a milled rice storage device 53 above the hopper 52, for example, commercially available milled rice can be stored in the storage device 53.
It is convenient to measure the required amount at the same time as grinding rice at the same time.

In the above-mentioned stirring type non-rice washing machine, the bran removing section is provided only in a part of the hopper in the circumferential direction, and the hopper is provided with the white rice discharge opening and the openable and closable white rice discharge door. Following the structure of the conventional rice milling machine shown in FIGS. 7 and 8, a bran removing section may be provided in the entire circumferential direction of the hopper, and the hopper is not provided with a white rice discharge opening and a white rice discharge door, and the hopper is attached to the machine. It may be detachable. In the above example, the shape of many holes drilled in the bran removing portion is a long hole, but various shapes such as the circular hole and the square hole shown in the conventional example can be used as long as the bran can be discharged outside. Is available. For example, a wire mesh or expanded metal can be used as the bran removing portion.

[0023]

According to the method for producing non-washed rice and the stirring type non-washed rice machine of the present invention, the aleurone layer and the oxide film are efficiently removed from the polished rice, the taste is good, and rice, immature rice, discolored rice, etc. It is possible to obtain white rice which is free from contamination. In addition, according to the stirred riceless rice washing machine of the present invention, since the rice grain surface is a glossy and smooth surface, and the rice bran is well cut and there is almost no adhesion of the bran powder to the white rice after the polishing, the white rice after the polishing is used. It can be cooked as it is without sharpening or washing with water as in the past (it can be used as so-called non-washed rice). Therefore, it is not necessary to wash and grind the rice so far, and since the sharpening juice, which is a polluting source of large water pollution, does not need to be discharged as domestic wastewater, it is possible to contribute to the conservation of water quality at the household level.
