When the automatic switching condition from the circulation side to the discharge side of the circulation / discharge switching valve 36 is not established even though the sorting state of the rice is stable, the sorted brown rice is operated by operating the discharge circulation switching switch SW6 at the operator's discretion. It is possible to perform efficient hulling work by shifting to the discharge hull sorting work.

  Further, when the circulation / discharge switching valve 36 is switched to the discharge side, the circulation / discharge switching valve 36 can be switched from the discharge side to the circulation side by operating the discharge circulation switching switch SW6 at the operator's discretion. It is possible to quickly prevent the rice cake from being mixed into the finished brown rice due to the sudden change in the sorting state of the sliding sorter.

  In addition, a discharge circulation changeover switch SW6 is disposed near a work position 44b provided in a portion near the mixed rice sorting unit 3 of the operation guide guide body 44c that is long in the left and right to form the operation guide groove 44. Therefore, the operator can operate the discharge circulation switching switch SW6 while checking the sorting state of the swing sorting plate 15 of the mixed rice sorting unit 3 nearby, and can quickly and easily cope with the sorting state.

  The discharge circulation switching switch SW6 can be switched when the operation lever 32 is operated to the work position 44b. That is, if it is configured so that it can be switched when it is in the initial position, the rice hull sorting operation can be started with the circulation / discharge switching valve 36 on the discharge side, and the mixed rice tank 24 is set without the operator's intention. This is because the finishing discharge process becomes possible without waiting for detection of the amount or more.

  When the main motor M1 is stopped when a power failure or an operator operates the operation switch SW1 during the finish discharge process and the main motor M1 is restarted, the circulation / discharge switching valve 36 is temporarily switched from the discharge side to the circulation side. . When the mixed rice upper limit sensor SE3 detects that the mixed rice tank 24 has a mixed rice amount greater than or equal to a predetermined amount after a predetermined time has elapsed (for example, 30 seconds later), the circulation / discharge switching valve 36 is changed from the circulation side to the discharge side. Switch to. Thereby, when interrupting and restarting during the sorting operation, the rice cake can be smoothly sorted while preventing the rice cake from being mixed into the finished brown rice.
