PROBLEM TO BE SOLVED: To automatically reduce the amount of broken rice generated during a rice-polishing operation. SOLUTION: This apparatus consists of a sampling- and weighing-device 5 of rice during polishing, a detecting-device 8a of the amount of broken rice contained in sampling rice, a computing-device 8b of the changing amount of the broken rice, a comparing- and evaluating-device 8c of computed result in comparison with a broken rice standard, and a changing-device 8e by which the compared and evaluated result is transferred to an automatic control device 9 so that just the desired command variables such as the speed of roll-rotation, the load current of a roll-driving motor and the flow rate of the rice, of the polishing rice apparatus can be momentarily changed. Since such a process becomes unnecessary that the generating state of the broken rice is checked by the eye and that the target data is manually changed, unmanned operation can be carried out, and further, since the generation of the broken rice can be reduced, improving the quality of sake (Japanese rise wire), and saving the time and the electric power for polishing rice will be expected.
