The grain transfer section 2 has a cylindrical grain transfer tube 21 and a screw roll 22 arranged inside the grain transfer tube 21, and a grain transfer chamber 23 for transferring rice grains is formed between the grain transfer tube 21 and the screw roll 22.

[0042] The grain feeding tube 21 has a raw material supply port 24 formed at the top of one end, and a raw material supply tube 25 is disposed in the raw material supply port 24, while the other end is open. The screw roll 22 is mounted on a main shaft 26 that is rotated by a drive motor (not shown).

[0043] A raw material supply hopper 27 is connected to the raw material supply tube 25. A shutter 28 is provided on the raw material supply hopper 27, and the amount of raw material brown rice supplied from the raw material supply hopper 27 to the grain sending tube 21 is adjusted by the opening degree of the shutter 28.

[0044] The polishing section 3 comprises a cylindrical or polygonal polishing tube made of a porous wall such as wire mesh, in this case a rice polishing screen 31 with slits provided throughout the screen, and a polishing roll 32 disposed within the rice polishing screen 31 and coaxially with the screw roll 22, and a polishing chamber 33 for polishing rice grains is formed between the rice polishing screen 31 and the polishing roll 32.

[0045] The polishing chamber 33 communicates with the grain transfer chamber 23 at one end, and polishes the rice grains transferred from the grain transfer chamber 23 within the polishing chamber 33, while the other end is provided with a discharge port 34 for discharging the polished rice grains, and the discharge port 34 is closed by a pressure lid 35 whose compression strength can be adjusted. Further, at the other end of the polishing chamber 33, a whiteness meter 4 is provided for detecting the whiteness of the rice grains polished in the polishing section 3. The whiteness meter 4 can be provided at any location where it can detect the whiteness of the rice grains polished in the polishing unit 3, such as below the discharge outlet 34.

[0046] The whitening roll 32 is formed with a plurality of air blast holes 36, and air is supplied from an air blower fan (not shown) through a hollow portion (not shown) in the main shaft 26 and blasted from the air blast holes 36. A dust collection chamber 37 is provided around the polishing chamber 33 between the rice polishing screen 31 and the rice polishing machine body, and the dust collection chamber 37 communicates with a dust collection duct 38 provided below.

[0047] In the rice polishing machine 1 according to an embodiment of the present invention, the raw brown rice supplied to the raw material supply hopper 27 is sent to the raw material supply port 24 via the raw material supply tube 25, and is then supplied from the raw material supply port 24 into the grain transfer chamber 23. The raw material brown rice supplied to the grain sending chamber 23 is then transferred to the polishing chamber 33 side by the screw roll 22.

[0048] The raw material brown rice transferred to the polishing chamber 33 is agitated by the polishing rolls 32, and is polished by friction between the rice grains while moving toward the discharge outlet 34, where it pushes open the pressure lid 35 and is discharged. At this time, the whiteness of the polished rice grains is detected by the whiteness meter 4 provided at the other end of the polishing chamber 33.

[0049] In the polishing chamber 33, bran is generated by polishing the raw brown rice. The bran is discharged from the slits in the rice polishing screen 31 through the dust collection chamber 37 and into the dust collection duct 38 by air blown from the blower holes 36 formed in the polishing roll 32.

[0050] Figure 2 shows a control block diagram of a rice polishing machine. Figure 3 shows an explanatory diagram of an example of the operation section of a rice polishing machine. The rice polishing machine 1 in the embodiment of the present invention is equipped with a control unit 5 that performs feedback control of the milling precision adjustment means 39, such as the pressure lid 35, the milling roll 32, and the shutter 28 provided in the raw material supply hopper 27, based on the whiteness of the rice grains obtained by milling raw material brown rice detected by the whiteness meter 4.

[0051] The control unit 5 is equipped with an operation unit 6 that can set a target whiteness, and controls the pressure of the pressure lid 35 in the milling accuracy adjustment means 39, the rotation speed of the milling roll 32, the opening degree of the shutter 28 provided on the raw material supply hopper 27, etc. so that the whiteness of the rice grains after milling detected by the whiteness meter 4 matches the target whiteness.

[0052] The operation unit 6 is, for example, an operation panel provided on a control panel, and as shown in Fig. 3, has an adjustment button 61 that allows adjustment of the whiteness of rice grains after polishing. It also has a setting button 62 for setting the target whiteness.

[0053] For example, in the whiteness adjustment operation, the operator inspects the whiteness of the polished rice grains visually or with a handheld whiteness meter, adjusts the whiteness of the polished rice grains by operating the adjustment button 61, and then turns the setting button 62 to "ON." Then, the whiteness of the rice grains detected by the whiteness meter 4 at the time the setting button 62 is turned "ON" and displayed on the product whiteness display unit 63 is stored and set in the control unit 5 as the target whiteness, and the target whiteness is displayed on the target whiteness display unit 64.

[0054] The rice polishing machine 1 in the embodiment of the present invention stores and sets the whiteness of the rice grains after polishing, detected by the whiteness meter 4 included in the rice polishing machine 1 itself, as the target whiteness, in the control unit 5, and can polish the rice while controlling the pressure of the pressure lid 35 in the polishing accuracy adjustment means 39, the rotation speed of the polishing roll 32, the opening of the shutter 28 provided in the material supply hopper 27, etc., so that the whiteness of the rice grains after polishing, detected by the whiteness meter 4, matches the target whiteness, thereby enabling auto-cruise-like control.

[0055] Furthermore, the rice polishing machine 1 in the embodiment of the present invention is equipped with input means 7 for inputting raw material information including the place of origin, variety, and year of production of the raw material brown rice; storage means 8 for registering and saving, as control information, operating conditions such as the pressure of the pressure lid 35 in the milling precision adjusting means 39, the rotation speed of the milling roll 32, and the opening of the shutter 28 provided on the raw material supply hopper 27 when the target whiteness is stored and set in the control unit 5 by operating the setting button 62 to "ON," together with the raw material information and the target whiteness, and for creating a database; and selection means 9 for identifying the raw material information and the target whiteness of the raw material brown rice from the database stored and registered in the storage means 8, and for reading out the control information.

[0056] In the rice polishing machine 1 according to the embodiment of the present invention, when raw brown rice is made by mixing brown rice of different origins, varieties, or years of production, the input means 7 can be used to input raw material information including the origin, variety, year of production, and usage ratio of each piece of brown rice.

[0057] Furthermore, the rice polishing machine 1 in the embodiment of the present invention can store and register the control information together with the target whiteness in association with the raw material information of the raw brown rice in the memory means 8 when adjusting the whiteness of the rice grains, during the rice grain polishing process, or after the rice grain polishing process is completed.

[0058] Here, the input means 7 and the selection means 9 can be an operation terminal such as a personal computer or a smartphone, the operation unit 6, or the like. The storage means 8 may be a storage unit of a personal computer or a server.

[0059] When a server is used as the storage means 8, the storage means 8 can be provided separately and independently from the rice polishing machine main body that performs the polishing process by making the storage means 8 capable of communicating with the control unit 5 of the rice polishing machine 1 via a communication means.

[0060] The rice polishing machine 1 in the embodiment of the present invention uses the selection means 9 to identify the raw material information and the target whiteness of the raw brown rice, reads out the control information stored and registered in the memory means 8, and starts the milling process of the raw brown rice based on the control information. This improves the production reproducibility of the whiteness quality of rice grains and prevents variations in the whiteness quality of rice grains obtained when the same raw brown rice is milled.

[0061] Furthermore, when milling the same raw brown rice, the rice milling machine 1 in the embodiment of the present invention eliminates the time required for an operator to inspect the whiteness of the rice grains visually or with a handheld whiteness meter or the like at the start of operation and adjust the whiteness, thereby shortening the preparation time for operation and improving product productivity.

[0063] The rice polishing machine 1 according to the embodiment of the present invention uses the "whiteness" as an index representing the polishing state of rice grains. 」 By using this, the whiteness of rice grains can be improved. quality It is possible to carry out milling processing so that the

[0064] In the above-described embodiment of the present invention, the "increase in whiteness" of rice grains can also be used as an index representing the polishing state of rice grains. In this case, by measuring the whiteness of the raw material brown rice in advance, the increase in whiteness of the rice grains after polishing can be determined from the difference between the whiteness of the raw material brown rice measured by the whiteness meter 4 and the whiteness of the rice grains after polishing.

[0065] Furthermore, in the above embodiment of the present invention, a pre-polishing whiteness meter for detecting the whiteness of the raw material brown rice before polishing can be provided above the raw material supply hopper 27, and the increase in whiteness of the rice grains after polishing can be determined from the difference between the whiteness of the brown rice detected by the pre-polishing whiteness meter and the whiteness of the rice grains after polishing detected by the whiteness meter 4.

[0066] The rice polishing machine 1 in the embodiment of the present invention described above can polish rice grains so that the product yield of the rice grains is constant in addition to the whiteness quality of the rice grains by using "increase in whiteness" as an index representing the polishing state of the rice grains.

[0067] Figure 4 shows an explanatory diagram of an example of a rice milling facility. The rice polishing machine 1 in the embodiment of the present invention can be used, for example, in a rice polishing facility equipped with a plurality of rice polishing machines with the same specifications. In the example shown in Figure 4, rice polisher No. 1 is the rice polisher 1 and the main rice polisher 11, and the database stored and registered in the storage means 8 of the main rice polisher 11 can be shared with other rice polishers No. 2 to No. 4 via wireless or wired communication means.

[0068] The other rice polishers No. 2 to No. 4 are then able to identify the raw material information and the target whiteness of the raw brown rice from the database stored and registered in the storage means 8, read out the control information, and start polishing the raw brown rice based on the control information.

[0069] In the rice milling facility according to the embodiment of the present invention, for example, when the same raw brown rice is milled in a rice milling facility equipped with multiple rice millers of the same specifications, the other rice millers No. 2 to No. 4 can start milling the raw brown rice based on the control information stored and registered in the memory means 8 of the main rice miller 11, thereby improving the production reproducibility of the whiteness quality of the rice grains in the rice milling facility and preventing variation in the whiteness quality of the rice grains.

[0070] Furthermore, in the rice milling facility according to the embodiment of the present invention, when the same raw brown rice is milled using multiple rice milling machines with the same specifications, it is possible to eliminate the time required for an operator to inspect the whiteness quality of the rice grains in each rice milling machine at the start of operation and adjust the whiteness, etc., and it is also possible to start milling using multiple rice milling machines simultaneously, thereby improving product productivity.

[0071] In the example shown in Figure 4, one rice polisher 1 is provided in the facility as the main rice polisher 11, but this is not limited to this. For example, all rice polishers in the facility can be the rice polisher 1, and each storage means 8 can be made available to each other via communication means.

[0072] FIG. 5 shows an explanatory diagram of an example of an operation management system for a rice mill. The rice polishing machine 1 in the embodiment of the present invention described above can be used, for example, in a rice polishing machine operation management system that manages the operation of a plurality of rice polishing machines with the same specifications.

[0073] The other rice polishers No. 2 to No. 4 can be remotely controlled from the central control room 10 to identify the raw material information and the target whiteness of the raw brown rice from the database stored and registered in the memory means 8, read out the control information, and start polishing processing of the raw brown rice based on the control information.

[0074] In an embodiment of the present invention, when the same raw brown rice is milled using multiple rice mills of the same specifications that are installed in different remote locations, the rice milling machine operation management system can remotely control from the central control room 10 and start milling the raw brown rice in each rice mill based on the control information stored and registered in the memory means 8 located in the central control room 10. This allows the operation of multiple rice mills to be remotely controlled from the central control room 10, improves production reproducibility of the whiteness quality of the rice grains in the multiple rice mills, and prevents variation in the whiteness quality of the rice grains.

[0075] Furthermore, when the same raw brown rice is milled using multiple rice mills of the same specifications that are installed in separate remote locations, the rice milling machine operation management system in an embodiment of the present invention can eliminate the time required for each operator to inspect the whiteness quality of the rice grains in each rice milling machine at the start of operation and adjust the whiteness, etc., and can also start milling processing simultaneously in multiple rice milling machines, thereby improving product productivity.

[0076] In the example shown in FIG. 5, one rice polishing machine 1 is provided as the main rice polishing machine 11, but this is not limited to this. For example, all rice polishing machines can be the rice polishing machine 1, and the storage means 8 of each rice polishing machine 1 can be managed together in a single server or the like, allowing them to be used interchangeably.

[0077] In the rice polishing machine according to the embodiment of the present invention, the polishing roll 32 is described as a friction type roll, but is not limited to this and may be, for example, a grinding type roll. Furthermore, in the embodiment of the present invention, the rice polisher 1 has been described as being a horizontal rice polisher, but it may also be a vertical rice polisher.

[0078] The present invention is not limited to the above-described embodiment, and it goes without saying that the configuration can be appropriately modified without departing from the scope of the invention. [Industrial Applicability]
