Then, as shown in FIG. 2A, among the beans B to be sorted, cracked or deformed beans Bb, garbage D, etc. rise along the rotation of the sorting conveyor 2 and the higher side end of the sorting conveyor 2 Fall from the part. The dropped beans Bb are collected in the defective product collection container 8 through the high-order chute 4. Beans Bb, dust D, etc. that have been cracked or deformed in this way are eliminated, and beans with a good shape (including defective beans Bb such as fine scratches and soiled beans in addition to good beans B) are sorted and conveyed. As shown in FIG. 5B, the shutter 5 at the lower end of the lower side of the shutter 5 is spread over the width of the shutter 5 and stays while rolling (does not move in the horizontal direction in plan view). Among them, defective beans Bb such as fine scratches and soiled beans are taken out by hand-sorting by visual inspection and collected in a collection container 6 for hand-sorting. At the time of the collection, the opening 3a is narrowed by the shutter 5 in the closed position so that the defective beans Bb being manually selected do not enter the opening 3a of the lower chute 3, so that the defective beans Bb Is not accepted by the lower chute 3 by mistake. As a mode of taking out at this time, a mode of picking up by picking with an instrument, chopsticks, tweezers or fingers, taking in with an instrument, or sucking is exemplified. Next, when the visual hand sorting is finished, the shutter 5 is switched to the open position as shown in FIG. Then, the non-defective beans remaining on the sorting conveyor 2 are collected together in the non-defective product collection container 7 via the lower chute 3.

  According to the bean sorter 1 of the present example configured as described above, when the shutter 5 is placed in the closed position and the bean B to be sorted is put into the sorting conveyor 2, the bean B is broken or deformed. The beans Bb and the trash D that have risen along with the rotation of the sorting conveyor 2 fall from the higher end of the sorting conveyor 2. Beans Bb, dust D and the like that have been cracked or deformed in this way are eliminated, and beans with good shape (including defective beans Bb such as fine scratches and soiled beans in addition to good beans B) are sorted and conveyed. Because it stays while rolling at the shutter 5 at the lower end of the above (it does not move horizontally in plan view), it does not cause a sense of car sickness and is efficient at your own pace It has the advantage that it can be visually selected. Then, when the visual sorting is completed and only the good beans Ba remain on the sorting conveyor 2, the good beans Ba are gathered from the lower end by switching the shutter 5 to the open position. It can be recovered.

  Further, the lower side end portion is provided with a lower side chute 3 for receiving the beans Ba falling from the lower side end portion, and the lower side chute 3 is formed in a cylindrical shape having an opening 3a for receiving the beans B. The shutter 5 is configured to narrow the opening 3a so that the beans B do not enter the opening 3a of the lower chute 3 when in the closed position.
