[0002]

2. Description of the Related Art In recent years, it has been gradually performed to measure the quality of brown rice and white rice samples and to refer to the measured data. For example, in places where paddy and brown rice are purchased from producers, such as agricultural cooperatives, the quality of brown rice is relatively important, while in stores that sell directly to consumers, the quality of white rice is important. Often watch.

[0003] As quality measuring means for measuring the quality of these rice, there are appearance quality measuring means for measuring appearance quality,
There is an internal quality measuring means for measuring the internal quality. As the appearance quality measuring means, the sample rice is irradiated with visible light to measure the transmitted light and the reflected light, and color tone analysis is performed by calculation based on these measured values. Quality measurement such as grain sizing, bluish immature grain, blackish damaged grain due to insect eating, brownish colored grain, dead rice without transparency, etc., if the sample rice is white rice , Quality measurement of complete grains that are not deformed, powdery material that is in the form of powder, crushed grains that are crushed and small, damaged grains that are blackened by insect eating, brown colored grains, etc. A configuration for performing this is known. Further, as the internal quality measuring means, there is known a configuration in which a sample rice is irradiated with near-infrared rays to calculate the content of various chemical components and a quality evaluation value inside the sample rice to perform internal quality evaluation. ing.

[0004]

However, conventionally, the quality of a sample of brown rice or white rice is measured to recognize the measured data of the quality of any sample rice, or the quality of a sample of brown rice or white rice is measured. However, while emphasizing the measurement data of one of the brown rice and the white rice, the measurement data is merely referred to the other measurement data, and the measurement data is only displayed on separate display screens.

[0005] Therefore, even if the measured data is viewed, only one aspect of the quality of the brown rice or white rice sample can be known, and the idea of comparing the quality measured data of the brown rice sample with the quality measured data of the white rice sample is obtained. There was no such thing, and a lot of trouble was required, such as printing both measurement data, when comparing.

An object of the present invention is to provide a display system of a rice quality evaluation device which can easily compare measured data relating to the quality of brown rice and white rice samples. .

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a display screen of a display system of a rice quality evaluation device according to an embodiment of the present invention;
FIG. 2 is a diagram schematically showing a rice quality evaluation device according to the embodiment of the present invention.

As shown in FIG. 2, sample rice to be measured is put into a hopper 11 and distributed by a distribution device 12 into two systems, a measurement system 13 and a rice mill system 14. 2
One measuring line 13 of the systems is further divided into two systems by another distribution device 15, one of which is connected to the appearance quality measuring means 16 and the other of which is connected to the internal quality measuring means 17. The other milling line 14 of the two systems is connected to milling means 18, and a three-way valve 19 is interposed in the middle of the milling line 14 to divide the metering line 20. 20 is connected to the measuring device 21.

The appearance quality measuring means 16 is provided with a transport section 22, a detecting section 23, and a sorting section 24. The sample rice supplied to the external quality measuring means 16 is detected by the transport section 22 one by one. 23, the sample rice is irradiated with visible light to measure transmitted light and reflected light, and color tone analysis is performed by calculation based on these measured values. The appearance grades of the sampled rice are classified into six ranks: sized, unripe, damaged, colored, dead, and cracked in the case of brown rice, and complete grain and powdery in the case of white rice. 5 of quality, crushed grain, damaged grain, colored grain
The sort is determined according to the type of rank, and the sorting unit 24 sorts each rank. At this time, the number of grains for each rank is measured by a counter in the sorting unit 24, and the grain weight for each rank is measured by the measuring device 25. From the measured values, the ratio for each rank including the sizing ratio is calculated.

In the internal quality measuring means 17,
Irradiate the sample rice with near-infrared light and perform spectroscopic analysis in a non-pulverized state.
Measure fatty acid content and internal quality evaluation value. The internal quality evaluation value is determined based on the sensory test and the physicochemical test standard of the Japan Grain Inspection Association, and is determined from the taste evaluation value, stickiness value, hardness value, etc. of the sampled rice.

On the other hand, the rice milling means 18 is provided with a rice milling intensity changing device 26 capable of changing the milling load or lengthening or shortening milling time. By adjusting the device 26, the yield of milled rice (“milling accuracy”) can be changed and controlled.
The sample rice milled by the milling means 18 is weighed by the measuring device 21 and then sent to the measuring system 13 by the transport system 28. A three-way valve 29 is interposed in the middle of the transport system 28. By switching the three-way valve 29, the sample rice weighed by the measuring device 21 can be measured by the measuring system 1.
3 or return to the rice polishing means 18 again to perform the rice polishing step a plurality of times.

Here, the control means 27 reads the measurement data of the appearance quality measuring means 16 and the measurement data of the internal quality measuring means 17, respectively, stores the data in the storage means 30, and displays the data on the display means 31 as needed. Also,
The milled rice yield is calculated from the ratio of the initial weight of the sampled rice weighed by the scale 21 to the weight of the milled rice, and the milled rice yield changing device 26 is adjusted to control the change of the milled rice yield. The weighing data of the weighing machine 21, the polished rice yield in the polished rice means 18, the control output of the polished rice intensity changing device 26, etc. are stored in the storage means 30 and displayed on the display means 31 as needed.

When measuring the quality of rice, a sample of brown rice is put into the hopper 11 and the distribution device 1
In step 2, the sample rice of the brown rice (referred to as sample brown rice) is distributed to the measuring system 13 and the milling system 14. Brown rice distributed to the measurement path 13 is further distributed by the distribution device 15 for two more times.
It is distributed to the system, sent to the appearance quality measuring means 16 and the internal quality measuring means 17, and the appearance quality and the internal quality are measured as described above, and each measurement data of the sample brown rice is displayed on the display means 31. And stored in the storage means 30.

On the other hand, the sample brown rice distributed to the rice milling line 14 is first sent to the measuring device 21 via the measuring line 20.
After the initial weight is measured, the rice is milled by the milling means 18. The sample rice after milling is weighed by the scale 21,
The rice yield is calculated as described above. If the milled rice yield has not reached the target value, the sampled rice is returned to the milling means 18 and milled again.

Then, the white rice (referred to as “sample white rice”) that has reached the target milled rice yield is transferred from the transport system 28 to the measurement system 1.
Sent to 3. 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 each measurement data is displayed on the display means 31 and the storage means 3 is displayed.
0 is stored.

In this case, as shown in FIG. 1, on the display means 31, the measurement data of the sample brown rice and the measurement data of the sample white rice are simultaneously displayed on a single screen. Specifically, a sample number, a brand, a production year, a production area, and a grade are displayed at an upper end portion of the display screen of the display means 31, and a weight and a yield of the polished rice as a milling measurement column are displayed at an upper left side of the display screen. (Weight of polished rice after polished rice / weight of brown rice before polished rice), the number of times of rice polishing, and intrinsic yield (weight of completely polished rice / weight of polished rice) are shown as numerical data, and the yield is displayed as a pie chart. 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 in the column of internal quality of sample brown rice, and the moisture, protein, amylose, and internal quality evaluation values are respectively shown. Are displayed in association with each other as a radar chart, and further, on the upper right side of the display screen, the appearance quality column of sample brown rice and Te, sizing of sample brown rice, immature grains,
The percentages of body split, damaged, colored and dead rice are shown numerically and in a pie chart.

In the center of the lower part of the display screen of the display means 31, the moisture, protein, amylose, fatty acid content and quality evaluation value of the white rice are shown as numerical data in the column of the internal quality of the sampled white rice.
The amylose and the internal quality evaluation values are displayed as a graph in association with each other as a radar chart, and further, on the right side at the bottom of the display screen, as the appearance quality column of the sampled white rice, the sized, immature, broken and damaged grains of the sampled white rice are displayed. ,
The percentages of colored grains and dead rice are indicated by numerical values and pie charts.

As described above, since the measurement data of both the brown rice sample and the white rice sample are displayed on the screen, the quality measurement data of the brown rice sample and the quality measurement data of the white rice sample can be easily compared. From these comparison results, it is possible to recognize the properties of sample rice that cannot be determined from only one of the measured data.

For example, as shown in FIG. 1, in a state where the yield is constant, if the ratio of broken grains of a white rice sample is large, despite the small percentage of broken grains of a brown rice sample, the rice milling process is performed. It can be inferred that the material is easily broken. In addition, although the protein is relatively high in the portion near the outer periphery of rice, if the percentage of protein in the white rice sample is very small compared to the protein in the brown rice sample, it can be determined that the degree of rice polishing is too high, It can be guessed that setting the rice milling strength to a lower value can make the rice milling more appropriate and produce large white rice. Similarly, when the ratio of protein in the white rice sample is smaller than that in the brown rice sample, it can be determined that a large amount of protein is contained in the bran generated in the rice polishing process.

In addition, the unripe grains of brown rice are those that have stopped growing and remain small, and those that have grown generally despite their bluish tinge, and when they are polished, they have good perfect grains. For example, if the percentage of whole grains in the white rice sample is larger than the percentage of sized grains in the brown rice sample, and the percentage of immature grains in the brown rice sample is large, but the powdery quality of the white rice sample is small, then milling complete grains In this case, it can be determined that even if there are many unripe grains of the brown rice sample, it is highly likely to be obtained as complete grains after milling and has high added value.

As described above, it is possible to newly recognize the properties of the sample rice, which can be obtained only by comparing the quality measurement data of the brown rice sample with the quality measurement data of the white rice sample.

Further, a standard value of a predetermined brand may be stored in the storage means 30 and displayed as a comparison value.
According to this, it can be easily determined that the quality of the sample rice is close to that of the brand in any quality item.

Further, in the above-described embodiment, the case where numerical data and figures are displayed at one time in one screen is shown, but the present invention is not limited to this, and the display screen is displayed on a continuous screen. By scrolling, both the quality measurement data of the brown rice sample and the quality measurement data of the white rice sample can be displayed, and the screen can be divided into left, right, up, down, etc., and the quality measurement data of the brown rice sample, the quality of the white rice sample Even if the measurement data, the quality measurement data of the brown rice sample of the specified brand rice, and the quality measurement data of the white rice sample can be easily switched, the quality measurement data can be easily compared with each other, and the properties based on the comparison result and other properties Similarities and differences with the brands.

Further, in the above embodiment, the case where the quality of both brown rice and white rice is measured by the appearance quality measuring means 16 and the internal quality measuring means 17 has been described. Means 17
Needless to say, the same operation and effect can be obtained even if only one of them is provided.

[0027]

As described above, according to the present invention, the brown rice quality measurement result and the white rice quality measurement result are edited and displayed on the screen and displayed, so that the brown rice quality measurement result and the white rice quality measurement result can be easily obtained. Comparisons can be made, and from these comparison results, it is also possible to recognize various properties of the sampled rice that cannot be determined from only one measurement result.
