However, it was difficult to remove these foreign substances only with the above-mentioned stone crusher.

In view of the above, the present invention aims to eliminate the drawbacks of the conventional apparatus by providing a specially configured net for removing foreign substances in the process of raising brown rice to the rice milling machine.

[Means for solving the problem]

The present invention seeks to solve the above-mentioned drawbacks, and in a throwing frame 31 of an elevator 9 or 11 for frying brown rice to be subjected to whitening treatment, a receiving net 33 for receiving brown foreign matters and receiving foreign substances having a large diameter is provided. A receiving position in which the end of the receiving net 33 on the side of the brown rice throwing away from the throwing position is pivotally supported by a lateral support shaft 34, and the receiving surface of the receiving net 33 is inclined upward as the distance from the brown rice throwing position increases. The net 33 is configured to be switchable between a standing throwing position in which the free end side is upward and a throwing position between the receiving surface in the standing throwing position of the receiving net 33 and the discharge port 36 to the outside of the machine. A foreign matter removing device such as a rice milling machine having the space 35 is configured.

[Functions and Effects of the Invention]

Brown rice and foreign substances mixed into it are lifted by the elevator 9 or 11
Is supplied to the next processing unit through the throwing frame 31. At this time, the receiving surface of the receiving net 33 is in a receiving position with an upward inclination as the distance from the throwing position of the brown rice increases, and the brown rice thrown from the bucket of the elevator 11 is received by the receiving surface of the receiving net 33 and the brown rice leaks. At this time, the foreign matter remains on the receiving surface and gradually accumulates on the side away from the throwing direction of the brown rice on the lower slope side.

After the milling operation is completed, or in the middle of the operation, a handle or the like is operated to switch the receiving net 33 from the receiving position to the standing position for throwing up foreign matter. Then, the foreign matter deposited on the free end side of the receiving surface of the receiving net 33 on the lower side of the inclination is thrown into the foreign matter throwing space 35 by the reversing action, and is collected in the receiving box 38 through the discharge port 36.

When receiving foreign matter to the receiving net 33, the foreign matter received on the receiving surface of the receiving net 33 flows down and accumulates along the inclined surface in a direction away from the throwing direction of brown rice, so that the main stream of brown rice collides Foreign matter accumulates in the lower part of the slope away from the position, and does not hinder the passage of brown rice continuously thrown.
