The driving is executed a plurality of times every predetermined time, and the driving of the rotary valve 16 is stopped when the predetermined time elapses thereafter.

  The user of the automatic rice milling apparatus may gradually add brown rice to the charging hopper 4 after starting the rice polishing drive, and the driving of the rotary valve 16 corresponding to the charging fee does not end the feeding of the brown rice. There was a problem that brown rice remained in the charging hopper 4. In addition, when brown rice is fed out for a long time so that no brown rice remains in the input hopper 4, the brown rice is fed out more than the number of coins to be inserted, and the unpolished brown rice is discharged into the milled tank 13. There is. Therefore, in this embodiment, it is intended to solve such a problem.

  Next, the control flow shown in FIG. 15 will be described. When the drive switch RVS of the rotary valve drive motor 41 is turned on for the first time, the rotary valve 16 is driven for a predetermined time by a command from the control unit. Next, the second and third drive switches RVS are turned ON at predetermined time intervals by the output of the control unit, and the rotary valve 16 is continuously driven for a predetermined time (step S1). Is turned on (step S2), and a charging prohibition measure for the charging hopper 4 is taken (step S3).

  Next, the stop timer for ending the driving of the rotary valve 16 is started (step S4), and then the rotary valve 16 driving switch RVS is determined ON / OFF every predetermined time (steps S5 to S7). When the timing of the stop timer is ended due to the OFF state of the drive switch RVS, the drive of the rotary valve 16 is stopped (step S8).

  As described above, since the drive of the rotary valve 16 is stopped when a predetermined time has elapsed after the brown rice feeding drive switch of the feeding hopper 4 is turned on a plurality of times every predetermined time only during the operation of the first unit price. Even if brown rice is additionally added to the charging hopper 4, the brown rice can be prevented from remaining and the above-mentioned problems can be solved.

The rice mill drive motor 45 has a rice mill load current sensor (not shown). And configured to detect the load current value during the rice milling operation.

  Thus, when the rice milling operation is started, the lower limit sensor (not shown) of the feeding hopper 4 is turned on to detect the fed brown rice, and the load current detection value of the rice mill load current sensor (not shown) is higher than a predetermined value. Determines that the rice milling machine 10 has polished brown rice, and if the detected value of the load current sensor (not shown) of the rice milling machine is lower than a predetermined value, the rice milling machine 10 is polishing white rice. judge. Accordingly, it is possible to detect the white rice thrown into the throwing hopper 4 while reducing the cost.

  In addition, when it is detected that the rice milling operation is white rice as described above, it may be configured to polish white rice at a lower price than brown rice. That is, when white rice is polished, for example, 50% of the brown rice polished rice amount is returned at the end of the milling operation. In this way, the rice price can be rationalized.

  Thus, the white rice in the charge tank 68 is returned to the rice mill lift 8 as the valve motor 76 is fed out. Accordingly, the milled rice once passed through the milling machine 10 and made into a milled rice state waits until the first milling process for one loading port is completed by the charge tank 68, and the rice mill lifting machine 8 again from the charge tank 68. It is the structure which isolate | separates and removes the moss adhering to the white rice surface layer by the rice milling machine 10 by returning and circulating. In addition, as mentioned above, in order to allow cooling air to act on the milled rice in the charge tank 68 and the circulation guide chute 67 portion provided to supply the charge tank 68, the rice polishing process in the rice milling machine 10 set for the rice polishing process is performed. At this time, by receiving cooled white rice from the charge tank 68, the rice polishing can be performed without excessively increasing the temperature. Therefore, the automatic rice milling apparatus with a rice polishing function can suppress quality deterioration due to an excessive temperature rise while continuously and rapidly processing from rice polishing to rice polishing.

Next, the operation of the above configuration will be described.
When raw brown rice is put into the feeding hopper 4 and the polishing switch 34 is pushed, the drive motor 41 of the rotary valve 16, the stone remover 6, the rice mill 10 and the like are driven to rotate. At this time, the compression plate 17 of the rice mill 10 is automatically set to the upper white setting state.

  The raw brown rice is sent from the input hopper 4 to the stone lifter lift 5 as the rotary valve 16 rotates, and is cerealed, and the stone remover 6 moves foreign matter such as stones to the upper side of the slanted net surface. It is separated and sorted from brown rice flowing down. Next, the sorted brown rice is supplied to the foreign matter removing device 7 and the sawdust is supplemented and separated on a rough net surface, and the sorted brown rice is supplied to the rice mill lift 8 and cerealed and supplied to the rice milling tank 9 of the rice mill 10. The

  The brown rice in the milled rice tank 9 is sequentially supplied into the main body of the rice mill 10 and is subjected to the whitening treatment by the resistance action of the compression plate 17 set to white. When the amount of subsequent brown rice increases, the compression plate 17 is pushed open. It is sent to the guide chute 65. At the beginning of the milling, since the unmilled state is discharged, the open / close valve 66 of the guide chute 65 is in a standing state, and the milled rice is fed to the charge tank 68 through the circulation guide chute 67 for a while and then further passed through the rotary valve 75. It is returned to the machine elevator 8 and supplied to the rice mill 10 together with the subsequent brown rice (initial rice milling).

  When the initial milling process for a predetermined time is completed, the circulation rotary valve 75 is stopped, the milling process by the milling machine 10 is continued, the open / close valve 66 is switched, and the milled rice is stored in the charge tank 68 (milling process). . Here, if the number of coins to be inserted is 300 yen or less, the whole whitened portion of the introduced brown rice can be supplied to the charge tank 68, so that the whitening process is performed until a predetermined operation time corresponding to the number of coins to be inserted has elapsed. The entire amount of polished rice that has undergone the polishing process is stored in the charge tank 68.

  After the predetermined time has elapsed after the rotary valve 16 of the charging hopper 4 has been stopped and output, the milled rice stored in the charge tank 68 is activated and supplied to the lifting machine 8 for the milling machine when the circulating rotary valve 75 on the charge tank 68 side is activated. Grain milled rice is supplied again from the milled rice tank 9 to the milling machine 10 and undergoes a polishing action. Thus, the pressing plate 17 waits in the above white state and removes the moss adhering to the surface layer of the polished white rice supplied, and is taken out to the whitening tank 13 through the guide chute 65.

  The polished rice at the initial stage of polishing is unpolished, and the initial polishing cycle is set in the same manner as the initial polishing process, and the unpolished portion at the initial stage of polishing is stored in the charge tank 68 and waited. When this initial polishing cycle is performed for a predetermined time, the on-off valve 66 is raised to discharge the polished rice to the circulation guide chute 67 side.

  When the initial polishing process of the rice polishing is completed, the guide chute 65 on the discharge side of the rice milling machine 10 is switched so that the on-off valve 66 falls from the standing state and closes the bottom opening 66b, and the polished rice is subjected to the polishing process. 13 is taken out. It should be noted that at the end of the process, the initially polished polished rice stored in the charge tank 68 is returned to the rice mill 10 and finally the polishing operation is completed.

  Further, it is preferable to set the polished rice that has been stored in the charge tank 68 to be polished by the rice mill 10 at the following timing. That is, as shown in FIGS. 24 and 25, the open and closed valve 66 provided in the guide chute 65 on the discharge side of the rice milling machine 10 is laid down in advance, the bottom opening 66b is closed and the polished rice is taken out. At the same time, the driving of the circulating rotary valve 75 is started first, and the charged milled rice is supplied to the milling machine 10 in a circulating manner. Next, the milling machine 10 is driven for a predetermined time corresponding to the amount of milled rice charged, the milled milled rice is taken out into the milling tank 13.

  When the rice milling machine 10 is driven and the milled rice in the charge tank 68 is supplied to the rice milling machine 10 after a predetermined time, the efficiency of the rice milling machine 10 is reduced. Causes a problem that the whole amount of polished rice stored in the charge tank 68 cannot be polished.

  However, with the above-described configuration, the rice milling machine 10 is driven for a predetermined time after the milled rice stored in the charge tank 68 is started to be supplied to the rice milling machine 10. And the above problems can be solved. FIG. 24 is a time chart showing the operational relationship, and FIG. 25 is a control flowchart.
