Description

[Detailed Description of the Invention] [Industrial Application Field] Generally, a small amount of bran layer (aleurone layer) remains on the surface of rice grains made by polishing brown rice with a rice milling machine, and the rice grains produced during the rice milling process are It is mixed with so-called sugar, which consists of aleurone, endosperm, and germ flour. The bran layer left on the polished rice grains is polished off by ``rice polishing'' using ordinary household tap water, and the rice is washed away with water along with any sugars and other substances that may be present. The polished rice is transferred from the rice washing container to the rice cooker and cooked. Since washed rice grains contain water, they tend to be more brittle and more likely to break than dry rice grains.

The present invention relates to a dry rice polishing device for polishing rice in a dry state using water.

[Prior art] Conventional rice polishing devices of this type include, for example, Japanese Patent Application Laid-Open No. 58-672.
There is an apparatus described in Publication No. 17. The configuration of the device described in this publication is shown in FIG.

In FIG. 12, (a) is a rice washer, and (b) is a rice cooker located below it. (c) is the rice washer itself, (d)
is the hopper, (e) is the water level adjustment pipe, (f') is the discharge hole, (
g) is a valve, (h) is a rod, and (i) is a solenoid. (j) is the water supply pipe, (k) is the solenoid valve, (
)) is a trough. Moreover, (m) is a drainage ditch, and (n) is a drainage pipe.

In a device with such a configuration, after putting a predetermined amount of rice into the rice washer main body (c) from the hopper (d), when a switch (not shown) is turned on, a timer is activated and the solenoid valve (k) opens, and water is supplied. Water is fed from the pipe (j) as shown by the arrow, and flows from the lower end of the trough (1). Due to this inflow, the rice in the rice washer body (c) is also drawn into the trough (1), discharged from the upper part of the trough (+), and drawn in again, thereby being circulated and washed. Excess water in the main body (C) overflows and enters the drain (+n), and is discharged from the drain pipe (n).

After water is supplied for a specified period of time and rice is washed, the solenoid valve (k)
is closed by the operation of the timer. Then, the solenoid (i
) is actuated and opens the valve (g) by pulling up the rod (h). When the valve (g) is opened, the discharge hole (f
) through the rice washing machine body (c) and the water level adjustment pipe (e
), the amount of water is adjusted and the water falls into the rice cooker (b).

[Problems to be Solved by the Invention] Conventional automatic rice polishing devices are configured to wash rice using water as described above. Therefore, supply/drainage work and associated equipment are required to connect piping for supplying and discharging water for washing rice to the device. In addition, hygienic measures such as measures to prevent the growth of mold based on the use of water that is prone to mold growth are also essential, which increases the size of the entire device.

In particular, unlike rice polishing, where rice is polished while visually observing the rice, the rice is polished mechanically, which causes the rice grains to become brittle due to moisture content and break up, reducing the quality of the cooked rice. This had the fatal problem of reducing the accuracy of rice polishing.

The present invention was made in order to solve the problems of the conventional apparatus as described above. It grinds rice while the rice grains are hard without using water, and there is no need for special supply and drainage equipment for grinding rice. In addition, the present invention aims to realize a dry rice polishing device that is compact, hygienic, and highly accurate in polishing rice without breaking the rice grains of cooked rice.

[Means for Solving the Problems] A first means of the present invention includes a rotatable outer cylinder provided with an intake port in the lower part and an outlet in the upper part, and a rotatable outer cylinder arranged coaxially within the outer cylinder and rotated around the outer cylinder. A ring-shaped rice polishing chamber with varying gap spacing is formed, and the cylinder part has multiple slits.It has a fixed inner cylinder with a separation chamber to separate the sugar mixed inside, and a fixed inner cylinder with a separation chamber to separate the sugar mixed inside, and a rice polishing chamber provided on the outside of the outer cylinder. The main body consists of an outer case provided with a storage chamber for storing the rice, a regulating plate for regulating the direction of movement of the rice in the storage chamber, taking it in from the intake port and transporting it to the rice polishing chamber, and a drive source for rotating the outer cylinder. This dry rice polishing device is equipped with a bran removing means for removing sugar adhering to the gaps between the slits, and/or a bran collecting means for collecting the dropped sugar.

In the second means, the bran removing means is constituted by a brush that moves inside the inner cylinder.

Furthermore, the third means comprises a bran collecting means for collecting bran by passing air into the inner cylinder.

[Function] In the first means of the present invention, the rice in the storage chamber is taken into the rice polishing chamber one after another from the bottom of the rotating outer cylinder. The rice grains taken into the rice grinding chamber move in irregular directions and are pushed upwards while being stirred. On the way up, the bran layer and germ on the surface of the rice grains are scraped off and polished by the slits provided in the rice polishing room and the rice grains coming into contact with each other. The polished rice thus pushed up to the upper part of the rice polishing chamber while being subjected to the rice polishing action is sent through the delivery port. When the rice polishing operation is interrupted or completed, the bran removing mechanism is driven by the electric motor, and the bran removing brush moves up and down in the inner cylinder. The bran adhering to the gaps between the slits and the inner wall of the inner cylinder is then swept off and collected in the tray.

In addition, in synchronization with the driving of the bran removing mechanism, airflow for collecting bran is generated in the ventilation passage inside the inner cylinder, and is mixed into the bran and rice that are swept away by the bran removing brush. Bran and garbage are collected in a rice bran collection bag attached to the downstream side.

The maximum value Lm and minimum value Ln of the gap in the direction orthogonal to -X are Lm, respectively, when the length of an ordinary rice grain is Lr.
It is selected such that it falls within the range of ≦2Lr and Lr≧Ln [FIG. 8].

The rice polishing operation of the apparatus of the present invention having such a configuration will be described below with reference to FIG. 7 and subsequent drawings.

Polished rice (12) is charged into the storage chamber (R1) from the input path (56) of the upper case (21), accumulated from the bottom inclined surface, and stored. A part of the polished rice (12) put into the storage chamber (R1) enters the vicinity of the bottom of the rice polishing chamber (R2) through the gap between the intake port (63) and the regulation plate (46).

Here, when the electric motor (2) is driven at a constant speed, its rotational force is transmitted to the output shaft (3), drive pulley (4), and belt (
5) to the driven pulley (6) on the main body (1) side. The rotational force transmitted to the driven pulley (6) is further transmitted to the drive shaft (33) and driven wheel (44), and the outer cylinder (6o) is supported at the bottom and top by surface bearings (42) and (52). ) begins to rotate in the direction of the arrow in Figure 7. When the outer cylinder (6o) rotates and faces the intake port (63) or the regulation plate (46) as shown in Fig. 2, the regulation plate (46) removes the polished rice (12) near the entrance of the intake port (63). Spring pressure is applied in the centripetal direction. As a result, the rice is forced into the milling room (12) or the rice polishing room (R2) through the three intake ports (63). The pushed-in polished rice (12) receives the pushing force of the subsequently pushed-in polished rice (I2), and is pushed up into the rice polishing room (R2) together with the polished rice (12) that has already entered. At the same time, the rice grains (14) that were pushed through the intake port (63) and came into contact with the spiral (76) were exposed to the grains shown in FIG. 8(A).

As shown in (B), a force F having horizontal and vertical components Fv and Fh is applied by the rotating outer cylinder (60). The force F inclined at the helical angle α works together with the pushing force of the regulating plate (4B) to push the polished rice (12) up into the rice polishing chamber (R2). The individual rice grains (14) that have been pushed up are moved between a rotating hexagonal outer cylinder (60) and a fixed circular inner cylinder (70).
) due to the difference in cross-sectional shape from (L+)-(
Due to the change in Ln)-δ, the polished rice (12) as an aggregate rises in the rice polishing room (R2) while being moved and stirred in irregular directions.

In this case, the rice grains (
14), the negative part fits into the slit (71) and the sharp opening edge (7) of the slit (71)
In step 3), the bran layer on the surface is scraped off. In addition, the rice research room (R2
) The bran layer is also peeled off due to the rubbing motion of the rice grains (14) due to the weight from the upper layer and the pushing up of the lower layer. In addition, the rice grain (14) that has ascended near the germ removal slit (7I) so that the germinal hole (16) faces the germ removal type (72) is removed from the germs remaining in the germinal hole (16) and The germ powder is scraped off. Furthermore, the rice grains (14) that have reached the upper part of the rice polishing chamber (R2) are rubbed and polished by the mesh having an arcuate surface of the mesh (72). Furthermore, the surface of each rice grain (14) is polished by the friction between the rice grains. Then, the shaved bran powder, germ powder, and mixed small debris are removed as sugar (15) through the slit (71).
) and the mesh (72) to the separation chamber (R3), where it is separated from the polished rice (12), falls through the separation chamber (R8), and is collected in the tray (2B). The polished rice (13), which has been pushed up to the top of the rice grinding chamber (R2) while undergoing grinding and polishing in a dry state, is transferred to the delivery port (57).
sent from. Thereafter, the rice is transferred from the rice polishing process to the rice cooking process, where it is put into a rice cooker, where an appropriate amount of water is added, and then heated and cooked.

Here, polished rice (12) is taken into the rice polishing room (R2).
The delivery amount is (Q), the polishing degree is (K), and the outer cylinder (60)
When the number of rotations is (N), there is a relationship as shown in FIG. As shown by the curve (q), the feed rate (Q) of milled rice (12) increases as the speed increases from low speed, reaches a constant value when it exceeds R2), and reaches a constant value when it exceeds (R3). Decrease rapidly. On the other hand, the degree of polishing (K) shown by the curve (k) shows a very high value at low speeds near (nl) where the delivery ji (Q) is small, and is almost inversely proportional to the increase in the number of revolutions (N). and decreases. Therefore, the rotational speed of the outer cylinder (60) (
Rice polishing efficiency can be kept high by selecting N) near the rotational speed (na) corresponding to the point (p) where the two curves (q) and (k) intersect. In addition, by utilizing the relationship that the characteristic of the curve (k) is almost inversely proportional to the number of rotations (N), we can respond to customer requests within a wide range of rice, from brown rice to white rice, including germ rice, based on the number of rotations (N). It is also possible to set the degree of polishing (K).

When the rice polishing operation is completed, the output of the electric motor (2) is switched to the bran removing mechanism (80), and the drive roller (81) is rotated. The wire (83) is pulled by the rotation of the drive roller (81), and the brush (84) begins to move within the endless path. Move the brush (84) and guide roller (82)
When it comes into contact with the drive roller (81), it passes in a linear shape while brushing or lying down. When the brush (84) reaches the inner cylinder (70), the electric motor (2) rotates intermittently in forward and reverse directions.

As a result, the tip of the brush (84) moves up and down and enters the slit (71) and mesh (72), and the sugar (15 ) are swept away. Sweeped sugar (1
5) is placed in the tray (28) along with the sugar (15) that has already passed through the gap between the slits (71) and fallen from the separation chamber (R3).
). After the bran removal operation has been carried out for a certain period of time, the wire (83) without the brush (84) is sent into the separation chamber (R3), and the electric motor (2)
The power is turned off, the driving of the bran removing mechanism (80) is stopped, and the bran removing operation is completed.

FIG. 11 is an explanatory diagram of the main part of another embodiment of the present invention. (90) in FIG. 11 is a bran collecting mechanism, which is provided at the bottom of the main body (10) of the rice polishing device. (91) is a blower of the rice bran collecting mechanism (90), and (92) is a fan. The blower (91) is removably provided at the lower end of the drive shaft (33), and is connected to the electric motor (2) via the driven pulley (6). In addition, in this embodiment, the outer case (20) is made to have a substantially airtight structure, and the holding frame (27) is also formed in the shape of a ventilated bottomed cylinder. A filter or a bran collecting bag (93) is provided on the inner peripheral surface of the holding frame (27).

In the embodiment shown in FIG. 11, the outer cylinder (
60) rotates, the polished rice (12) is pushed up into the rice polishing chamber (R2) as described above. The rice grains (14) that have been pushed up are passed through the slit (
71) etc., the bran layer on the surface is scraped off or polished. On the other hand, due to the rotation of the electric motor (2), the driven pulley (
6) and rotates together with the blower (91) or the drive shaft (33). When the blower (91) rotates, air is sucked in from above the inner cylinder (70), passes through the separation chamber (R3), and then exits to the side of the holding frame (27), as shown by the hollow arrow. It is formed. As a result, the bran, germ flour, or polished rice (
Sugar content (15) consisting of bran and garbage mixed in J2),
It is sucked along this ventilation path and captured by the filter or bran collection bag (93) on the side of the holding frame (27). Then, the filter or bran collecting bag (93) in the holding frame (27) is periodically removed.
sugars removed or exchanged and collected (15)
or be disposed of or collected.

In the above-mentioned embodiment, the case where the outer cylinder (60) or the plate material is formed into a hexagonal shape is illustrated and explained, but it is also possible to integrally mold the outside into a circular shape and the inside into a hexagonal shape. It is not limited to a rectangular shape, as long as the gap between the rice polishing chambers (R2) changes. Further, the germ removal mold (72) may be provided on the upstream side of the slit (71), on the tributary side, or on both sides, and the position, number, etc. of the slit (71) are not necessarily limited to each embodiment. In addition, although the example has been described in which the inner cylinder (70) and the outer cylinder (60) are arranged concentrically with the axis X-X being vertical, the axis
-X may be inclined at an angle of about 0 to 60 degrees with respect to the vertical. Additionally, an annular storage chamber (R1) is provided around the rice polishing chamber (R2), with three or four intake ports (63).
The case where the polished rice (12) is taken into the rice polishing room (R2) is shown, but the polished rice (12) is taken into the rice polishing room (R2) from the separate storage room in the main body (20) through a single intake port. You may also import it into In addition, although we have explained the case in which the rice that has risen in the rice polishing chamber (R2) is directly sent out from the delivery port (57), there is a delivery port (57) and a storage chamber (R1) near the top of the rice processing room (R2). A switching valve may be provided to switch the flow.

In the reflux method, if the rice is polished at the rotational speed N of 01 in Figure 10 and sent out at the rotational speed of 02, the selection of the rotational speed N is appropriate and there is no waste, and the degree of polishing (K) increases within the layer. You can grind rice efficiently while using it. In addition, milled rice (12) is mixed with white rice (
13) As explained in the operation of rice polishing, the inner cylinder (70
) and the outer cylinder (60) made of a wear-resistant metal material or the like, it can also be used for polishing rice to directly turn brown rice into white rice. Furthermore, although the case has been described in which the rice bran collecting mechanism (90) is driven during the rice polishing operation to collect the rice bran, the rice bran collecting mechanism (90) may be driven after the rice polishing operation is interrupted or completed, and the rice bran removal mechanism (80) You may also collect rice bran at the same time. If the bran removing mechanism (80) and the bran collecting mechanism (90) are driven synchronously, the bran removing and bran collecting actions are carried out in cooperation with each other, so that the accuracy of rice polishing can be greatly improved.

[Effects of the Invention] As explained above, the present invention has a rotatable outer cylinder provided with an intake port at the lower part and an outlet port at the upper part, and a rotatable outer cylinder arranged coaxially within the outer cylinder so that the gap interval changes around the circumference. A fixed inner cylinder that forms a ring-shaped rice polishing chamber and has a separation chamber that separates sugar mixed inside, a storage chamber provided outside the outer cylinder to store rice, and a direction in which rice moves within the storage chamber. A dry rice polishing device is constructed, which includes an outer case provided with a regulating plate that regulates the rice intake through the intake port and transports the rice to the polishing chamber, and a main body that includes a drive source that rotates the outer cylinder.

As a result, there is no need for supply/drainage work or associated equipment for a water supply/drainage system for washing rice. In addition, sanitary measures such as measures to prevent the growth of mold and rot due to the use of water are not required, and there are fewer measures to take against corrosion, and the entire device can be configured to be small and compact.

Moreover, since the rice grains are ground in a dry state, there is no breakage of the rice grains, and there is no problem that the quality of the cooked rice deteriorates and the accuracy of rice grinding is reduced.

In particular, the present invention constitutes a dry rice polishing device in which the main body is provided with a bran removing mechanism and/or a bran collecting mechanism. Then, the brush of the bran removal mechanism was driven to sweep away the bran, germ powder, etc. adhering to the slit and the surface of the inner cylinder. In addition, the airflow of the bran collecting mechanism sucks and collects the bran etc. in the slit. For this reason, it is possible to deliver highly pure white rice that contains almost no sugar. In addition, the occurrence of failure due to clogging due to sugar in slits and rotating outer cylinder bearings, etc.
It can also be prevented.

Therefore, according to the present invention, it is possible to provide a dry rice polishing device having various features such as a compact and sanitary overall structure and high rice polishing accuracy.
