And the grain used as a raw material is thrown into the inlet of the raw material charging tank 5. Then, when one of the whiteness selection buttons 63 is selected and the whiteness is set, the whiteness adjustment motor 73 is activated to set the position of the compression plate 12f. When these setting preparations are completed, the control unit 66 reads the number of inserted coins, calculates the operation time, and each unit of the rice mill facility starts operation over the calculated time.
[0026]
The grain put into the raw material feeding tank 5 is supplied to the stone lifter lift 6 by the rotary valve 13, cerealed by the stone lifter lift 6, and dropped into the stone remover 7. The grains dropped into the stone extraction device 7 are supplied to the rocking side of the swing sorting plate 7a. In the meantime, pebbles, foreign matter, etc. in the grains are sorted and conveyed to the rocking side by the rocking action of the rocking sorting plate 7a and the air blown from the blower fan 7b, and discharged from the stone discharge shunt 7d. On the other hand, the grain flows down to the swaying side of the swing sorting plate 7a and is supplied from the grain discharge port 7c to the supply unit 8a of the foreign matter removing device 8.
[0027]
The grain supplied to the supply part 8a of the foreign material removal apparatus 8 is supplied to the area | region n in the receiving plate part 20a of the sorting plate 20 shown in FIG. And the grain is diffused throughout the sorting plate 57, the grain falls into the drifting grain board 21 through the hole p, flows down as it is, falls from the grain dropping cylinder 24, the grain discharging cylinder 25, the transport ho -It is supplied to the hopper part 8a of the elevator 9 for rice milling apparatus through the sewing machine 27, and then dropped and supplied to the brown rice tank 30.
[0028]
On the other hand, swarf and the like that cannot pass through the hole p are transported through the porous surface 20c of the sorting plate 20 and the transport plate 20d, and are not mixed into the grain discharge tube 25 by the partition plate 20e. (Not shown). The grain supplied to the brown rice tank 11 is supplied to the whitening chamber 31 and is subjected to whitening so as to achieve a whitening degree set between the whitening roll 10b and the fine platinum net 10a. Then, the polished white rice is conveyed to the white rice tank 4 through the grain outlet 10e and appropriately collected in the operation room A.
[0029]
The soot generated during the whitening operation is stored in the soot storage hopper 33, and the soot processing is performed through the soot conveying path 40, the soot branch case 41, and the machine room side soot conveying path 42 by the suction and blowing action of the soot fan 34. It is conveyed by air to the section 11 and is collected in the bag 18a and 18b through the cyclone 15, the helix 16 and the hail discharge port 17a.空 気 The air conveyance by the fan is set to be strong, or when the operation room side culling extraction button 74 provided on the operation room side A is pressed, the inner branch cylinder of the 糠 branch case 41 is switched and the operation with the conveyance path 40 is performed. The chamber-side soot conveyance path 43 communicates, and soot is taken out by the soot take-out hopper 46 through the operation room-side cyclone 44.
[0030]
Here, with the progress of the rice milling work, when the culm stored in the culm bag 18b on the conveyance end side overflows from the culm discharge port 17b, the culm detection plate 19a is pressed by the culm and rotates toward the terminal side of the culm transport. To do. And if it rotates more than a predetermined angle, the limit switch 19c will detect by pushing the push rod 19d. When the limit switch 19c detects, the spiral drive motor 16a stops. Or you may make it alert | report.
[0031]
When the time set by the input amount elapses or when there is no more grain to be polished, the milling pressure in the milling chamber 31 decreases, and the load current value of the milling roll drive motor 32 detects a predetermined value or less. The elevators 6 and 9, the stone removing device 7, the foreign substance removing device 8, etc. are stopped, and the whitening roll drive motor 32 is stopped after a predetermined time has elapsed, and the whitening processing operation is completed.
[0032]
At that time, even after the whitening roll drive motor 32 stops, the soot fan drive motor 35 is driven for a predetermined time, thereby sucking the soot adhering to the inside of the whitening chamber 31 and the soot dropping cylinder 33. Then, when the above steps are completed, the rice milling facility ends all the steps. Next, the operation in the case of using the twice button 64 when whitening the grain once whitened will be described.
[0033]
A coin or a prepaid card that can secure an operation time commensurate with the grain amount is inserted into the coin mech 60 and the prepaid card slot 61. And the grain used as a raw material is thrown into the inlet of the raw material charging tank 5. Then, when the button for twice is pressed to select one of the whiteness selection buttons 63 and the whiteness is set, the whiteness adjustment motor 73 is activated to set the position of the compression plate 12f. When these setting preparations are completed, the control unit 66 reads the number of inserted coins, calculates the operation time, and each unit of the rice mill facility starts operation over the calculated time.
[0034]
While undergoing the same milling process as the one-time standard work process, the milling apparatus receives the milling process. At that time, the load current value of the milling roll drive motor 32 that detects the absence of grains in the milling chamber 31 is detected. The setting reference value is set low. And when it falls below the set reference value that has been lowered, it is determined that there is no grain, and thereafter, the same process as in the standard one-time pass is performed, and all the processes of the rice milling facility are terminated.
[0035]
Alternatively, a sensor for detecting the presence or absence of grain may be provided in the raw material charging tank 5 or the brown rice tank 30, and the whitening roll 10b may be stopped when a predetermined time elapses after the sensor detects the absence of grain. Next, the case where the high quality rice button 65 is used will be described. A coin or a prepaid card that can secure an operation time commensurate with the grain amount is inserted into the coin mech 25 and the prepaid card slot 61. And the grain used as a raw material is thrown into the inlet of the raw material charging tank 5. Next, when the high-quality rice button 65 is pressed and, for example, the whiteness selection button 17 (for example, upper white) is selected and the whiteness is set (step 3), the whiteness adjustment motor 36 is activated and compressed. The position of the plate 12f is set. At this time, the compression plate 12f sets a lower degree of whitening (for example, 5 minutes). When these setting preparations are completed, the control unit 66 reads the number of inserted coins, calculates the operation time, and starts operation of each unit of the rice milling facility over the calculated time (step 4).
[0036]
After the same process as the one-time operation process described above, the milling process is performed by the rice milling apparatus, but the grain that has been milled and discharged from the grain outlet 12e is opened by the reduction shutter 36 and the grain discharge trajectory is opened. By cutting off, the refined grains are stored in the reduction chute 37 that is reduced to the machine room B side. And after the grain detection sensor 80 determines that there is no grain in the raw material charging tank 5, when a predetermined time has elapsed, that is, when the last grain in the raw material charging tank 5 reaches the rice mill lifting machine 9. In addition, the grain in the reduction chute 37 is supplied to the lift 9 for the rice milling apparatus. Then, immediately after the grain, the refined grain is continuously supplied to the milling chamber 31, and the grain in the reduction chute 37 is subjected to finishing milling again in the milling chamber 31. Then, after finishing the whitening process of the second finish, when it becomes the polished rice of the set whitening degree, it is sequentially discharged into the white rice tank 4 from the grain outlet 12e.
[0037]
In this embodiment, the whitening process is described twice, but it goes without saying that it may be performed three times or more. By using the soot detection plate 19a as in the present embodiment, it is possible to detect that the soot overflows through the soot detection plate 19a, so that the soot adheres directly to the sensor when the soot is wet. Therefore, it is possible to prevent erroneous detection caused by sticking to the sensor, and to improve the detection accuracy of overflow of the bag 18b.
[0038]
Further, even when the air flow of the kite fan 34 is slightly strong, the kite can be prevented from being discharged out of the kite transfer kit 17 through the overflow hole 17c, so that a clean operation can be performed and the operator can There is little trouble with air volume adjustment. Further, when the overflow is detected, the hook 16 is configured to be stopped, so that it is possible to prevent a failure of the hook 16 caused by operating the hook processing unit 11 in an overflow state.
[0039]
Furthermore, by providing the limit switch 19c on the outside of the soot transfer soot, it is possible to prevent the soot that overflows from adhering directly to the limit switch 19c. improves.
