That is, the fine grains stored in the storage tank 3 under the control of the control unit 8 are cleaned in the polishing unit 2 and then sent to the full stone unit 5. The grains separated from the rice bran in the barn section 5 are raised to the inlet of the storage tank 3 by the grain section 6. The fine grain repeats this circulation cycle, and is finished into desired sake and rice.

2, enlarged sectional views of mainly the polishing part 2, the flow rate adjusting part 4, and the full stone part 5 are shown. Between the polishing unit 2 and the storage tank 3, a flow rate adjusting unit 4 for adjusting the flow rate of fine grains from the storage tank 3 to the polishing unit 2 is provided. The lower part of the storage tank 3 is molded into an inverted cone shape, and a cylindrical valve cylinder 44 is molded below it. And, the flow rate adjusting part 4 is equipped with the valve body 41 formed in the substantially conical shape which can move up and down in the inside of the said inverted cone cylinder.

One end side of the valve lever 42 responsible for raising and lowering the valve body 41 is engaged with the shaft portion 41a extending downward of the valve body 41 and protrudes outward from the valve cylinder 44. The other end side of the valve lever 42 is engaged with the lower end of the electric jack 43 supported by the support arm 45 so as to be able to rotate freely. With this configuration, the jack 43 is controlled by a control signal from the control unit 8, and the flow rate of fine grains flowing into the polishing unit 2 is adjusted.

The polishing unit 2 includes a grinding assembly 21, a polishing cylinder 22, and a discharge cylinder 23. The upper part of the polishing container 22 serves as a container for fine grains 24, and the base is fixed to the polishing part base 9. A part of the base is cut off to become the feed port 25. The grinding assembly 21 includes a constrictor 26, a pressing member 27, a grinding roll 28, and a roll stand 29, and is assembled around the constrictor 26. The grinding roll 28, the pressing member 27 and the roll rest 29 are all circular in plan view, and have a boss for the constriction 26 at the center. The constriction 26 is shaft-supported in the longitudinal direction with respect to the base portion base 9, and is held in the thrust direction (axial direction) by the two-point bearing mechanism 30, and also in the radial direction (axial direction). rotational direction) is rotatably supported.

The opening degree of the pressure regulating valve 38 is changed according to the pressure of the fine grains in the polishing chamber 35, and according to the air pressure of the pressure regulating valve 38 and the flow rate of the fine grains to the polishing cylinder 22, the following The fullness rate of the whitening room 35 is adjusted and controlled.

The grinding roll 28 is integrally formed by stacking a plurality of annular partial rolls vertically.

Each partial roll in this embodiment is made of aluminum alloy, and CBN abrasive grains are fixed to the outer peripheral surface of each partial roll by electrodeposition. In conventional GC grindstones (fired grindstones), it was difficult to remove irregularities in millimeters or to process a grindstone into a perfect circle, but the above-described electrodeposited grindstone of CBN abrasive grains is a machined product where the cost of the grinding roll 28 is Because of this, the roll main body is a perfect circle, and it is suitable for milling while aligning the fine grains with the surface of the grinding roll 28 in a state facing the side surface. In this way, in particular, circular polishing and flat polishing can be preferably carried out. Then, when the motor M is driven, the shrinkage 26 is driven via the manual pulley 37, and the grinding roll 28 rotates within the polishing cylinder 22.

In the polishing section 2, fine grains are transferred from the storage tank 3 through the receiving port 24 to the polishing chamber 35, and the fine grains are ground between the polishing cylinder 22 and the grinding rolls 28 (polishing). do. The fine grains passing through the polishing chamber 35 are taken in by the outer circumferential portion 36 of the roll stand 29, and then sent out from the transfer port 25 to the discharge cylinder 23.

The mixture of grains and rice bran sent to the discharge pipe 23 is separated into grains and rice bran while flowing through the bay part 5, and the separated grains are stored by the grain part 6 installed on the grain base 10 The grain is grained into the top of the tank (3). The fine grain repeats this circulation cycle, and is finished into desired sake and rice.

The control unit 8 in the present embodiment is capable of various setting operations in the rice milling apparatus 1 for casting, and the setting conditions by the operation manager and the quality state of polished rice by the grain discriminator not shown Based on the like, the rice milling device 1 for casting is controlled. Further, as shown in Fig. 1, the control unit 8 has an operation display unit 80 capable of displaying various setting operations, quality, and the like. The operation display unit 80 is constituted by a liquid crystal display having a touch panel. For example, an example of a display mode of a setting operation screen in the operation display unit 80 is shown in FIG. 3 .

On the display screen of the operation display unit 80 shown in FIG. 3 , a circular rice polishing icon 84, a flat rice polishing icon 85, and a spherical rice polishing icon 86 allowing selection of the polished rice shape of polished rice are displayed. . Then, the rice polishing shape is determined by touching the type of rice polishing desired by the operation manager with a finger, and the grinding roll selection mechanism 7 selects a spherical polishing roll 28A, a circular polishing roll 28B, and a flat polishing roll. One of the rolls 28C is configured to be automatically installed in the polishing unit 2 .

In addition, it is possible to set the rice polishing degree of polished rice in the operation display unit 80, and by touching the rice polishing degree DOWN icon 81 and the rice polishing degree UP icon 82 as appropriate, the rice polishing degree display unit 87 It is configured so that the degree of polishing to be set is displayed. And by touching the determination icon 83, setting conditions are fixed, and it is comprised so that the rice milling apparatus 1 for casting may operate.

Then, based on the table|surface described in FIG. 4, the control aspect of the rice milling apparatus 1 for casting in this embodiment is demonstrated.

As described above, in the present embodiment, the three types of milling shapes shown in the figure can be selected based on the conditions set by the operation manager, and the grinding roll selection mechanism 7 is selected according to the type of the set milling shape. As a result, any one of the spherical polishing roll 28A, the circular polishing roll 28B, and the flat polishing roll 28C is installed in the polishing section 2. The grain size of the roll abrasive grain of each grinding roll 28 is 40 mesh for spherical polishing roll 28A, 60 mesh for circular polishing roll 28B, and 80 mesh for flat polishing roll 28C. In addition, according to each rice polishing shape, the current value corresponding to the polishing load, the rotational speed of the grinding roll 28, and the flow rate of the fine grains to the polishing chamber 35 are controlled as shown in the figure, thereby producing polished rice having a desired polished rice shape. it is possible to do

In addition, as described above, in this embodiment, it is possible to set a desired degree of rice polishing. By presetting the parameters as shown in FIG. 4 in the controller 8, the current value corresponding to the polishing load, the rotation speed of the grinding roll 28, and the flow rate of the fine grains to the polishing chamber 35 can be adjusted and controlled more minutely. This makes it possible to produce polished rice having a desired degree of polishing. "80% polishing" corresponds to 20% polishing degree, "60% polishing" corresponds to 40% polishing degree, and "40% polishing" corresponds to 60% polishing degree, respectively. When rice polishing is set in the operation display unit 80, the current value corresponding to the above-described polishing load, the rotational speed of the grinding roll 28, and the flow rate of fine grains to the polishing chamber 35 are controlled as shown in FIG. It is controlled so that the fullness rate of the fine grains in the whitening room 35 is 33 to 50%.
