Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display system of a rice quality evaluation device for measuring the quality of sample rice and displaying the measured data.

[0002]

2. Description of the Related Art The handling of rice becomes very convenient if the taste can be expressed by a single evaluation value. However, since the taste is evaluated differently depending on the taste of the person, the taste value calculated based on the predetermined criterion is useful, but in a society where personal tastes and values are regarded as important as in the present, no one is expected. However, it is difficult to obtain a single acceptable taste value.

[0003] In response to such a problem,
It is conceivable to measure and display various data indicating the quality of rice, for example, by irradiating near-infrared rays to sample rice such as brown rice to calculate various chemical component contents and taste evaluation values indicating the internal quality of sample rice. Obtaining as numerical data is already known.

[0004]

However, even if a large number of numerical data of various measurement results are obtained and displayed as described above, it is necessary for an expert to recognize the characteristics of rice from only these numerical data. It was difficult and could not be easily recognized. For example, if the measurement item has little fluctuation, the situation may not be recognized even if the data value is high or low. Further, it has not been possible to easily determine whether the numerical data of the measurement result is a standard item or a good value or a bad value as the item. Therefore, it was not easy for an inexperienced handler to evaluate the rice.

An object of the present invention is to provide a display system of a rice quality evaluation device that enables even a person with little experience to easily recognize and evaluate the characteristics of rice. It is.

[0006]

In order to solve the above-mentioned problems, the present invention provides a quality measuring means for measuring the quality of a sample rice, and a method of displaying a plurality of measurement results of the quality measuring means in numerical values. Display means for enabling graphic display in association with measurement results.

[0007] In the above arrangement, by displaying a plurality of measurement results of the quality measuring means in association with each other and graphically displaying the results, it is possible to remarkably display quality characteristics of the sample rice which cannot be easily discriminated only by numerical display. Thus, the characteristics of the quality of the sampled rice that the measurement result data means can be easily recognized.

Further, the display means can display the corresponding position of the measured value within the numerical range between the maximum value and the minimum value based on each known measured data, so that the data of the measured result can be displayed as an actual maximum. Within the range between the value and the minimum value,
It can be easily determined what value the value indicates. That is, even if the data has a small fluctuation range, it can be easily recognized whether the data is a standard value, a good value, or a bad value.

In addition, the measured value and the comparison value can be superimposed and displayed by a graphic. More specifically, the comparison value is represented by a standard value which is an average value and an excellent value which is a delicious rice value. , It is possible to easily recognize whether or not the measurement result data of each measurement item of the rice is close to a standard value or an excellent value.

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 partially enlarged view of the display screen, and FIG. 3 is a view schematically showing a rice quality evaluation device according to an embodiment of the present invention.

As shown in FIG. 3, 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 milling 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 section 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. Then, the appearance grades of the sampled rice are determined into six types of ranks, ie, sized, immature, damaged, colored, dead rice, and broken rice, and sorted by the sorting unit 24 for 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 milling means 18 is provided with a milling intensity changing device 26 capable of changing the milling load or lengthening or shortening the 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
2, the sample rice is supplied to the measuring system 13 and the milling system 1
4 and distribute. The brown rice distributed to the measurement path 13 is further distributed to two systems by the distribution device 15 and sent to the appearance quality measuring means 16 and the internal quality measuring means 17 to measure the appearance quality and the internal quality as described above. Then, each measurement data of the brown rice is displayed on the display means 31 and stored in the storage means 30.

On the other hand, the sampled rice distributed to the rice milling line 14 is first sent to a measuring device 21 via a measuring line 20 and its initial weight is measured, and then the rice is milled by the rice milling means 18. The sample rice after milling is weighed by the measuring device 21 and the yield of milled rice 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 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 brown rice, the quality of the white rice sample is measured by the appearance quality measuring means 16 and the internal quality measuring means 17, and the measured data are displayed on the display means 31 and stored in the storage means 30. It is memorized.

In this case, as shown in FIGS. 1 and 2, the numerical value of each measurement data is displayed on the display means 31, and a plurality of measurement results are displayed in a graphic form in association with each other. That is, in the display screen of the display means 31, the yield (weight of white rice after milling / weight of brown rice before milling) is displayed in a pie chart in the column of rice measurement at the upper left, or brown rice and white rice at the upper and lower right. In addition to displaying the percentage of sized, immature, split, and other (damaged, colored, dead rice, etc.) in a pie chart, the appearance quality column in Fig. As shown, in the columns of brown rice and white rice internal quality at the upper center and lower part of the display screen of the display means 31, the moisture, protein, amylose, and internal quality evaluation values are graphically displayed in association with each other as a radar chart. I have.

At the origin of the radar chart, the minimum value or the maximum value (for example, when the water content of white rice is 10.0%) in each of the known measurement data in which the evaluation of the moisture, protein, amylose, and internal quality evaluation values is the worst. , The protein is 12.0%, the amylose is 25.0%, and the internal quality evaluation value is 30 points). At each end point of the radar chart, the maximum value or the minimum value in each of the known measurement data having the best evaluation is set. (For example, the moisture of white rice is 16.0
%, Protein is 4.0%, amylose is 15.0%, and the internal quality evaluation value is 100 points). The corresponding position of each measured value within these numerical ranges is pointed and connected by a line segment. The figure is displayed.

In addition to the measured values (shown by solid lines),
Standard value which is an average value (indicated by a dotted line: for example, moisture in brown rice is 14.5%, protein is 7.3%, amylose is 20.0%, and internal quality evaluation value is 70 points. 14.0%, protein 7.0%, amylose 20.0%, internal quality evaluation value 70 points)
And excellent value which is a value of delicious rice (indicated by a phantom line: for example, moisture in brown rice is 16.0%, protein is 6.5)
%, Amylose 18.0%, internal quality evaluation value 90 points, moisture in white rice 15.5%, protein 6.0%, amylose 18.0%, internal quality evaluation value 90 points) And are superimposed on the same radar chart as comparison values. Note that these values are stored in the storage unit 30 in advance, but these values may be set to be inputtable by an input unit (not shown).

With this configuration, it is possible to easily determine the value of the measurement result data within a practical numerical range. In other words, even for an item with a small fluctuation range such as a protein, even a person with little experience can easily recognize whether the measured data is an intermediate value, a good value, or a bad value. Can be. In addition, the measurement result can be easily compared with the standard value and the excellent value just by looking at the superimposed radar chart, so whether the measurement result data for each measurement item of the rice is close to the standard value or the excellent value, etc. For example, in the case shown in FIG. 2, it can be easily recognized that the softness of the rice is better than that of the standard rice because the protein is close to an excellent value.

In addition, by displaying the numerical value of the measurement result together with a figure such as a radar chart, the measurement result can be recognized more finely and accurately.
The relationship between the numerical value of the measurement result and the corresponding position within the numerical value range of the known measurement data indicated by the numerical value can be associated and recognized, and the viewpoint of the numerical value can be confirmed.

In the above embodiment, the case where the data of the moisture, protein, amylose, and internal quality evaluation value of the sample rice are displayed in association with each other on the radar chart has been described. However, the present invention is not limited to this. Needless to say, various data relating to the sample rice may be displayed in association with each other, and may be displayed not only in the radar chart but also in other figures such as a line graph.
Further, instead of the excellent value, a standard value of a predetermined brand may be stored in the storage means 30 and displayed as a comparative value. It can also be easily determined that it has properties close to the above brands.

Further, in the above-described embodiment, the case where numerical data and graphics are displayed at one time in one screen is shown, but the present invention is not limited to this. By scrolling the display screen, Both numerical data and figures can be displayed, the numerical data display screen and the figure display screen can be easily switched, and numerical data can be displayed directly near the designated position on the figure screen. When the display is performed in combination with the above, the movement of the viewpoint is further reduced, and the visibility is improved.

[0026]

As described above, according to the present invention, a plurality of measurement results relating to the quality of sample rice measured by the quality measuring means can be displayed not only numerically but also in graphic form in association with the measurement results. The characteristics of the quality of sample rice that cannot be easily discriminated by numerical display alone can be displayed in a prominent manner, so that even those with little experience can easily understand the characteristics of the quality of sample rice that the data of the measurement results mean Can be recognized.

The display means can display the corresponding position of the measured value within the range of the maximum value and the minimum value based on each known measured data, so that the data of the measured result can be displayed as the actual maximum value. Within the range between the value and the minimum value,
It is easy to judge what value it indicates, and even if the data has a small fluctuation range, even if you are a person with little experience, you can determine whether the data is a standard value or a good value or a bad value It can be easily recognized.

Further, the measured value and the comparison value can be superimposed and displayed in a graphic form. For example, the comparison value is constituted by a standard value which is an average value and an excellent value which is a delicious rice value. Thus, even a person with little experience can easily recognize whether or not the measurement result data of each measurement item of the rice is close to the standard value or the excellent value.
