On the other hand, the sample brown rice distributed to the rice milling line 14 is first sent to the measuring device 21 through the measuring line 20,
After the initial weight is measured, the rice is milled by the milling means 18. The sample rice of the polished rice (referred to as “sample polished rice”) is measured by the measuring device 21 and the yield of polished rice is calculated as described above. If the milling yield has not reached the target value, the sampled white rice is returned to the milling means 18 and milled again.

Then, the white rice which has reached the target milling yield is sent from the transport system 28 to the measuring system 13. Thereafter, in the same manner as in the case of the sample brown rice, the quality of the sampled white rice is measured by the appearance quality measuring means 16 and the internal quality measuring means 17, respectively, and the measured data and the comprehensive evaluation value are displayed on the display means 31. It is stored in the storage means 30.

Therefore, at the time when all the measurements are completed, as shown in FIG. 1, the measurement data of the sample brown rice, the measurement data of the sample white rice, and the comprehensive evaluation value regarding the appearance quality and the internal quality are simply displayed on the display means 31. It is displayed on one screen or a continuous screen (a screen that can be continuously viewed by scroll processing).

More specifically, the sample number, brand, year of production, place of production, and grade are displayed at the upper end of the display screen of the display means 31, and at the upper left side of the display screen, the white rice after milling is used as a milling measurement column. Weight, yield (weight of white rice after milling / weight of brown rice before milling), number of milling times, intrinsic yield (weight of complete grain of white rice / weight of milled brown rice) are shown by numerical data, and the yield is circled. It is displayed as a graph, and in the upper center of the display screen, the moisture, protein, amylose, fatty acid content and quality evaluation value of brown rice are shown as numerical data as the internal quality column of the sample brown rice, and the moisture, protein, amylose, and internal The quality evaluation values are displayed graphically in association with each other as a radar chart.

In this case, the comprehensive evaluation value is a sample polished rice quality evaluation value, a difficulty level of milling calculated from a final milling frequency of the milling unit 18 for the same sample until a predetermined milling yield is reached, and an excellent grain described later. It is calculated from the ratio by the following formula.

Overall evaluation value = (quality evaluation value of sample white rice +
Difficulty of milling) × Excellent grain ratio The difficulty of milling is calculated by subtracting the standard number of milling times from the final number of milling times and multiplying by a constant coefficient so that the value increases as the milling becomes easier. And
If the standard number of times of rice polishing is preset to three times, and the final number of times of rice polishing is six, the difficulty of milling is (3
−6) × 2 = −6 is calculated.

The excellent grain ratio is defined as the milling yield obtained by dividing the weight of the 1,000 sampled white rice by the weight of the 1000 sampled brown rice, and the weight of the complete grain selected from the 1000 sampled white rice as the sampled rice. It is calculated from the ratio to the intrinsic yield divided by the weight of the sized rice sorted from the brown rice (that is, the excellent grain ratio = (weight of the complete grain / weight of the sized rice) / (weight of the sample white rice / weight of the sample brown rice)). . As shown in FIG. 1, the sample white rice has a weight of 19.5 g, the sample brown rice has a weight of 22.3 g, and the weight of complete grains is 17.5 g.
When the weight of the sized granules is 19.0 g, the following calculation formula (17.5 / 19.0) {(19.5 / 22.3)}
An excellent grain rate of 1.05 is calculated from 1.05.

Based on these data, 72 points of the total evaluation value are calculated from the following formula (75-6) × 1.05 ≒ 72.

As described above, not only various measurement results are displayed, but also a comprehensive and single comprehensive evaluation value is displayed. It is easy for a person to recognize the comprehensive evaluation of sample rice. And, as a comprehensive evaluation value, the sample rice taste evaluation value, the stickiness value, the sample white rice quality evaluation value having a correlation with the hardness value, and the like, it is calculated from the product of the difficulty of milling and the excellent grain rate. In addition to the data on the taste evaluation and the like of the sample rice, the added value of the sample rice can be obtained comprehensively while taking into account the ease of milling and the degree of obtaining more excellent white rice in the rice polishing process. It will be.

Further, since the total evaluation value, the brown rice measurement result, and the white rice quality measurement result can be compared at a glance, not only can the overall evaluation value be easily recognized, but also the overall evaluation value is good. The measurement result that is the basis for the bad or bad condition can be recognized at the same time, and useful information can be obtained even for inexperienced rice handlers and skilled workers.
