Description

  The present invention relates to a grain determination device, a grain determination method, and a grain determination system, and more specifically, objectively and comprehensively recognizes the difference between grains such as brown rice, polished rice, non-washed rice, and cooked rice grains, pH value, etc. The present invention relates to a grain judgment device, a grain judgment method, and a grain judgment system.

  Conventionally, when determining the properties of grains such as brown rice, polished rice, etc., in order to examine the difference in color reaction for each grain, it is almost the case that draining the dyed grains in advance. This is because the color reaction proceeds if the grains are immersed in the dyeing solution, and the color fades if the grains are immersed in water. In addition, rice grains soaked in a liquid having a low osmotic pressure such as water swell with time and change in color and shape.

  However, even though the grains soaked in water or reaction reagent are drained, exposure of the dyed grains to the air will result in a “turtle-shaped crack” on the surface and a change in the “view”. I hated it.

  There was also a method of examining the color tone characteristics by reacting the colorant with the leachate, but this did not give a stable result unless the reaction time was strictly defined. Furthermore, when determining the pH value of a grain, many of the conventional pH dyeing methods have been captured by a square, but when dyed with a square, if there are grains with different pH values, they will affect each other, Therefore, there is a problem that an accurate measurement value cannot be obtained.

  In Patent Document 1, white rice is immersed in a tray in which water is stored, the white rice is imaged by a scanner after being left for a predetermined time, and the presence or absence of soaking broken grains is determined based on the imaging data. An inspection object state discriminating apparatus has been proposed.

However, in this cereal inspection object state discriminating device, since the rice is imaged with a scanner while the grain is immersed in water with low osmotic pressure, the white rice swells with time, and the shape There is a possibility that an accurate property determination cannot be obtained due to a change or the like. The present invention solves the problems of the invention according to Patent Document 1.

(1) (When determining the grain properties using hypertonic solution)
As shown in FIG. 5, first, for example, a required number of polished rice is prepared, and dyeing is performed on the polished rice using a coloring solution (step S1). As a dyeing method in this case, a method in which polished rice is put into a tester and a colored solution is added and left for a predetermined time, 72 grains of polished rice are put in each hole 2c of the compartment 2A, and the petri dish 2B filled with the colored solution is filled. Examples include a method of storing the compartment 2A and leaving it for a predetermined time.

  Next, the grain after finishing the dyeing process, that is, 72 dyed grains, is put in each hole 2c of the compartment 2A, and the compartment 2A is accommodated in the petri dish 2B filled with the hypertonic solution (step S2).

  Next, the petri dish 2B filled with the hypertonic solution and the compartment 2A containing the stained particles are set on the glass plate 25 of the imaging unit 3 (step S3), the lid 3a is closed, the light source 21, the mirror 23, the color The CCD sensor 22 is driven in the direction of the arrow as shown in FIG. 4 to perform image reading scanning on the stained particles, and the output signal of the color CCD sensor 22, that is, image data of the stained particles is transmitted to the computer main body 8 (step) S4).

  Next, in the computer main body 8, image analysis processing such as property determination such as dyed grain area, grain length, grain width, body split, and color tone histogram based on the dyed grain image data by the analysis judgment processing means 4 is performed. This is performed (step S5). Further, based on the determination result, the dyed grain image and its property information are associated with each other and visually displayed on the liquid crystal display 5 or printed out by the printer 7 (step S6).

  The above grain analysis method can be similarly applied to brown rice, non-washed rice, cooked rice grains, etc. in addition to milled rice, especially in the case of cooked rice grains, the complete grain for each rice grain from the color and shape imaging results. It is also easy to determine the quality of the cooked rice grains by determining whether the grains are crushed or quantified.

  According to the method for determining the properties of grains such as polished rice using such a hypertonic solution, the stained particles are imaged while the compartment 2A containing the stained particles is put in the petri dish 2B filled with the hypertonic solution. Image data is obtained.

  Therefore, it is not necessary to dry the dyed grains, the shape and color tone of the grains treated with the coloring reagent can be maintained for several tens of minutes to several hours, excellent effects such as preventing changes with time due to the swelling of the grains, The effect can be exhibited, and thereby the accuracy of the analysis result can be expected.

(2) (When determining the grain properties while using the coloring solution)
As shown in FIG. 6, first, for example, 72 grains of polished rice are put in each hole 2c of the compartment 2A (step S11), and the compartment 2A is accommodated in the petri dish 2B filled with the coloring solution and left for a predetermined time (step). S12).

  Next, the petri dish 2B filled with the coloring solution and the compartment 2A containing the stained particles are set on the glass plate 25 of the imaging unit 3 (step S13), the lid 3a is closed, the light source 21, the mirror 23, The color CCD sensor 22 is driven in the direction of the arrow as shown in FIG. 4 to perform image reading scanning on the stained particles (step S14), and the output signal of the color CCD sensor 22, that is, the image data of the stained particles is used as the computer main body 8. (Step S15).

  Next, in the computer main body 8, image analysis processing such as property determination such as dyed grain area, grain length, grain width, torso, and color tone histogram based on the grain image data by the analysis judgment processing means 4 is performed. This is performed (step S16). Further, based on the determination result, the dyed grain image and its property information are associated with each other and displayed visually on the liquid crystal display 5 or printed out by the printer 7 (step S17).

The above-described grain determination method can be similarly performed for brown rice, non-washed rice, cooked rice grains, and the like in addition to polished rice.
Further, in the above grain determination method, as an advantage when imaging using the color solution as it is, the presence of the color solution has little influence on the imaging of the coloration of the sample surface and can be ignored, and If the color reaction on the surface of the sample is relatively fast and stable, and there is little difference due to the time difference before and after the specified measurement time, it can be measured without draining for ease of operation. It can be mentioned that there is little color mixing for each grain since it is stored in the compartment 2A to cause a color reaction.

(3) (When judging the pH value of a grain)
In this case, as shown in FIG. 7, 72 holes 31 for grain alignment accommodation and dropping are provided in the main body portion corresponding to the compartment 2A and petri dish 2B, and the hole 2c of the compartment 2A. And a reagent bottle 33 containing a pH indicator. The grains accommodated in the 72 holes 31 are configured so as to be able to be dropped downward at a stroke by a one-touch operation of a slide plate with holes, for example, although not shown.

  First, as shown in FIG. 8, for example, 72 grains of polished rice are arranged in each hole 31 of the grain aligner 30 (step S21). Next, a pH indicator is put into the petri dish 2B, and the compartment 2A is set (step S22). Furthermore, the grain aligner 30 is mounted and dropped from the grain aligner 30 into each hole 31 of the compartment 2A one by one (step S23). Thereby, it is possible to simultaneously execute the dyeing process on 72 grains to be subjected to the determination process without time lag.

  After the grain of the milled rice falls into the pH indicator, a predetermined time, for example, 10 minutes later, the dyed grain remaining on the pH indicator is imaged by the imaging unit 3 in the same manner as described above (step S24), Image data of 72 polished rice grains is acquired and transmitted to the computer main body 8 (step S25).

  Next, in the computer main body 8, the analysis determination processing means 4 determines an average pH value for 72 dyed grains, a pH value for each grain, a pH value histogram for the entire 72 grains, etc. (step S26). The determination result is visually displayed on the liquid crystal display 5 or printed out by the printer 7 (step S27).

  According to such a method for determining the pH value of a grain, a dyeing process is performed for each required number of grains, and a determination result for each grain regarding the pH value, determination of an average value of the entire 72 grains, and the like. There is an advantage that the result can be obtained simultaneously.

  In addition, as in the case described above, it is not necessary to dry the dyed grains, the shape and color tone of the grains treated with the coloring reagent can be maintained for several tens of minutes, the change with time due to the swelling of the grains can be prevented, etc. For this reason, the accuracy of the analysis result regarding the pH value can be expected.
