Reference numeral 12 is a blower port provided in the friction polishing trochanter 8 and forms a gap formed by the porous wall bran removal whitening cylinder 4 and the cylindrical body 13 in the bran removal chamber 14. The bran removal chamber 14 communicates with the bran-collecting passage 15 through the waste bran chamber 16 and the blower pipe 17 to the suction port 19 of the bran collecting device 18. Bran collecting device 18
A bran-excluding filter plate 62 is mounted on the upper part of the above, and an upper part thereof is formed as an air exhaust chamber 20 and a lower part thereof is formed as a bran collecting chamber 21. Reference numeral 22 denotes an air exhauster, the air exhauster 22 communicates with the air exhaust chamber 20 through an air passage 23, and 24 denotes a through hole for exhausting the cleaning air after the bran removal.

Then, the impeller 25 for scraping bran is provided on the main shaft 5 below the spiral rotator 6.
And a pulley 26 provided at the lower end of the main shaft 5 and a pulley (not shown) of an electric motor are connected via a V belt 27. A rice discharge valve 29 is fitted to a refined product discharge port 28 provided at the bottom of the rice grain container 2, and the purified product discharge port 28 communicates with a discharge gutter 29.

Reference numeral 30 is a whiteness adjusting device, and a rotating rod 32 is rotatably connected to a fixed base 31 attached to one side wall of the machine frame 3 via a shaft 33. A stopper for mounting the weight 34 on the tip of the rotating rod 32.
A shaft 36 to which 35 is attached is provided, and a ball 37 at the lower end of the shaft 36 is loosely fitted to a resistor 38. A large number of ventilation holes are provided in the resistor 38, and the resistor 38 is slidably fitted to the air suction pipe 39 at the upper end of the friction whitening rotor 8.

Next, the operation of the above configuration will be described. When an electric motor (not shown) is driven, the rice grains in the rice grain container 2 are sent from the rice grain supply port 10 to the spiral rotator 6 and are lifted by the spiral rotator to remove the rice bran on the porous wall 4 and the friction whitening. The trochanter 8 and the whitening chamber 9 which is the main part are refined. The grain of rice that has been refined is
While the outflow is suppressed by the resistor 38 of the whitening degree adjusting device 30, it is discharged from the rice grain discharge port 11 and returned to the rice grain container 2.

Then, by operating the blower 22, the rice bran is sucked from the vent holes of the resistor 38 and blown out from the air outlet 12 through the air suction pipe 39 to reduce the rise in the rice temperature and the rice bran action. Can be promoted. Dust such as bran generated by the polishing action in the whitening chamber 9 is discharged into the bran chamber 14 from the through hole of the porous wall bran removal whitening cylinder 4. Dust such as bran discharged to the bran removing chamber 14 is sent from the bran collecting passage 15 to the draining bran chamber 16, is scraped by the impeller 25, and is sent from the blower pipe 17 to the bran collecting chamber 21 through the suction port 19. To be Dust such as bran separated by the debranching filter plate 62 is accumulated in the bran collecting chamber 21, and the purified air is discharged from the air exhaust chamber 20 through the air passage 23 to the outside of the machine through the through hole 24.

The white rice that has been circulated in the polishing chamber 9 several times and refined to a predetermined polishing accuracy is discharged from the refined product discharge port 28 through the discharge gutter 29 to the outside of the machine by rotating the discharge valve 29.

The whiteness of rice grains is adjusted by the number of weights 34 of the whiteness adjusting device 30. That is, for example, when the lapping accuracy is not so high, one weight 34A is used for polishing, the weight 34B is added when the lapping accuracy is increased, and the weight 34C is added when the lapping accuracy is further increased.

As described above, the method of adjusting the hammering accuracy by placing the weight on the vertical shaft is simpler in structure and easy to attach and detach than the method of adjusting the hammering accuracy by sliding the weight fitted to the horizontal axis. It has the advantage of being easy and not requiring positioning.

Next, when exchanging the friction polishing trochanter 8 and the porous wall bran-removing polishing cylinder 4 and cleaning the rice grain container 2, it is very easy to rotate the polishing degree adjusting device 30. it can. In other words, first, the weight 34 is removed from the shaft 36, and then the rotating rod 32 is rotated about the shaft 33 as a fulcrum to the position indicated by the chain double-dashed line (see FIG. 2). Then, the resistor 38 disengages from the air suction pipe 39, so that the upper surface of the rice grain container 2 is opened, and it is very easy and short-time to replace the friction whitening trochanter 8 or the like and to clean the rice grain container 2. You can

If the polishing work is not performed, the weight 34 can be stored in the weight storage shaft 40 as shown in FIG. 3 to prevent loss.

It is a transmitted light receiving element for capturing light. 44 is a light source lamp, 45 is a reflecting mirror, and 46
Is a reflected light receiving element that catches reflected light from rice grains.

Next, the operation of the above configuration will be described. During the polishing process, the rice grains flowing down along the machine wall of the machine frame 3 are
Light is emitted from a light source lamp 44 at 42. Then, the reflected light from the rice grain is received by the reflected light receiving element 46 via the reflecting mirror 45, amplified by an amplifier (not shown), and the amount of reflection is measured. Next, the transmitted light from the rice grain is received by the transmitted light receiving element 43, amplified by an amplifier (not shown), and the amount of transmission is measured. Further, the reflection amount and the transmission amount are calculated by an arithmetic element (not shown), and the whiteness is represented as the sum of the light reflectance and the light transmittance.

When the above small rice mill is used as a test rice mill, since it is a ventilated type, the bran does not remain in the rice grain container and the yield can be accurately measured. Further, by providing a whiteness degree digital display or the like in the whiteness degree measuring device, the whiteness degree can always be known accurately.
