Description

Automatic milled rice recovery rate checker

The present invention is a mechanical device for determining the milling yield of rice, and more specifically, by selecting only once a small amount of threshed rice samples, sorting, jehyun, brown rice screening, rice milling, white rice screening The present invention relates to a rice milling yield automatic determiner which automatically determines rice extraction rate, brown rice whiteness, and overall rice milling yield by simultaneously processing a series of milling processes and weighing the output of each process.

Rice is one of the main food resources, and methods for producing high quality rice have been sought from various angles. For this, quality control of rice is the first priority. The quality of rice depends on growing rice control, climatic condition, threshing and drying method after harvesting. If these conditions are not suitable, the quality of rice is unsatisfactory, snowy rice, and crayfish. The term 'bad taste' is abundantly generated so that the yield of perfect rice is greatly reduced.

Therefore, in the purchase of rice, it is objectively determined between the rice producer and the buyer to determine the purchase price according to the degree of rice production relative to rice production by accurately measuring and comparing the road yield, that is, the amount of perfect rice and bad rice, of the rice to be purchased. It is a preferred method of imparting fairness. On the other hand, if the determination of rice yield in rice is inaccurate, rice yield per rice yield is reduced due to management failure after harvesting. Decisions are urgently needed.

However, it is common to judge the quality of rice to be inspected manually by the visual inspection of the inspector at the time of rice purchase.In addition, the determination of low-grade rice having a large amount of bad taste cannot be judged objectively and accurately. , Grade 3,… Because of the fact that it is not possible to make a differential purchase according to the grade, the person who produced high-quality rice with a relatively high yield of rice is damaged. This problem has serious consequences for rice producers.

In addition, it is possible to determine rice milling yield step by step by using several manually operated machinery when purchasing rice. However, in this case, it takes much time and effort, and it is still subject to the subjectivity of the inspector. There is concern that it will occur.

On the other hand, government agencies collect rice samples from all over the country every year, and measure and notify the yield of rice produced by region.In this case, large scale rice plant facilities are used, which consumes a lot of rice samples and requires much time and effort. Will be. Moreover, since this is a sampling of a part of the area and it is measured, it cannot be used as a quality criterion for purchasing rice produced by individual farmers.

Accordingly, the present applicant has filed several test unit devices that can automatically determine the yield of each cutting step at the time of purchase of rice, and re-threats and selects only by injecting rice of threshed quantity using them once. The rice rice automatic determination machine (Application No. 96-33580) and brown rice are used for automatically and objectively and accurately determining the quality of rice by separately weighing complete and snowy brown rice. The 'whiteness automatic determination device (Application No. 99-30792)' which can automatically determine the whiteness by weighing each weight after separating it into perfect rice and loaves by processing them.

By the way, the rice grade automatic determiner and the automatic rate determiner can precisely determine the manifestation rate and the white rate respectively, but since they are separated from each other, there are some obstacles in the precision of the overall rice yield yield determination. In other words, the brown rice obtained from the rice quality automatic determination machine must be transported by hand and put into the automatic determination rate of the browning rate. Therefore, the brown rice rate obtained automatically from the first rice sample can be spilled. It is difficult to guarantee the transparency to be input to the determiner, which causes an obstacle to the precision of the rice yield determination. In addition, there is a problem that not only has to take the burden of manually transporting brown rice, but also calculates the rice yield of rice from the evaluating rate and the whitening rate obtained from each judging machine.

In addition, in order to organize the judgment results or issue a report, it is difficult to input the calculation results manually into the computer, and it is difficult to guarantee the transparency in the calculation or data input process by such a manual operation, which is bad for the reliability of the inspection results. Will be affected.

In view of the above-mentioned conventional problems, the present invention continuously performs a series of milling processes such as sorting, milling, brown rice sorting, rice milling, and white rice sorting by simply injecting a small amount of rice sample once. The purpose of the present invention is to provide a rice milling yield automatic determiner that can determine rice extraction rate, brown rice browning rate and milling yield automatically, accurately and objectively by weighing the weight of each output.

Another object of the present invention is to provide a rice milling yield automatic determiner capable of selectively determining only the rice brewing rate or the brown rice bran rate as necessary.

Still another object of the present invention is a small-scale rice milling automatic determination device that can be installed directly in a unit agricultural cooperative, etc., and can efficiently and efficiently purchase rice by quickly and accurately determining the expression rate, whiteness and milling yield of rice at the time of rice purchase.

Initially, the bucket 630 of each of the bucket elevators 600, 600 ', 600 &quot; is located at the lowest loading position of the frame 610, and the sedimentary rice discharged oil of the bucket conveyor 800 is The guide 850 and the sliding bucket 840 are located under the brown rice discharge chute 440 of the brown rice sorting unit 400 and the white rice discharge hopper 571 of the rice mill 500.

In this state, when the power switch is turned ON, the solenoid 539 of the metropolitan 530 is operated so that the white rice discharge damper 537 closes the white rice discharge port 535, and the balance 510 is driven at the upper portion thereof. 520 and the gross weight of the metropolitan part 530 and the caliber adjustment part 550 are zero-adjusted in the state which excluded the gross weight.

Subsequently, an arbitrary induction rate is input through the keyboard K of the computer C, together with the biographical information of the farmer and the rice varieties of the determination target, and a sample input signal is displayed on the monitor M as shown in FIG. 6. 200 to 500 g of the determination target rice sample is introduced into the rice inlet 111 of the front door 110. Then, the injected rice sample is loaded on the selected rice discharge chute 250 of the selection unit 200. When the rice sample is loaded in this way, the meter 260 coupled thereto measures the weight of the rice sample and outputs the weighing signal. Done. Accordingly, the weight value of the introduced rice sample is displayed on the display panel 151 installed in the front door 110 and transmitted to the computer C and displayed on the monitor M.

At this time, a portion of the rice sample introduced by the rice sample distribution means 130 mounted on the rice inlet 111 is distributed to the moisture measuring unit 120 and introduced. That is, when the rice sample is inserted into the rice inlet 111, the solenoid 134 of the distribution means 130 opens the opening and closing plate 132 for several seconds by a sensor (not shown), and thus the distribution hole of the rice inlet 111. The 111a is instantaneously opened so that a portion of the rice sample is introduced into the moisture meter 120 through the distribution pipe 131. Then, the moisture meter 120 measures the moisture content of the introduced rice sample and outputs the measured value, which is displayed on the display panel 151 and the monitor M, respectively. The rice sample of which the water measurement is completed is collected by the rice sample container 140 under the moisture meter 120.

Next, as shown in FIG. 5B, the solenoid 253 of the selected rice discharge chute 250 is operated in accordance with the instruction of the PLC and the computer C to open the chute door 255. Then, as shown in the virtual ship, the guide chute 252 is rotated toward the bucket 630 of the first bucket elevator 600 and at the same time the rice sample is located adjacent to the bucket through the outlet 254 of the Jeongseon rice discharge chute 250 630 is injected into.

When the rice sample is completely discharged into the bucket 630 and the weight of the rice sample in the selected rice discharge chute 250 becomes '0', the measured value '0' of the meter 260 is transmitted to the computer C. Accordingly, the motor 621 of the first bucket elevator 600 is driven in the forward direction to drive the chain 620 in the upward direction. Then, the bucket 630 mounted on the chain 620 is raised along the guide rail 611 of the frame 610.

When the bucket 630 reaches its first feeding position, that is, the fixed dog 641 installation position as shown in FIG. 14, the motor 621 is stopped by the position sensor 653. The roller 642 of 641 contacts the contact piece 638 formed in the slide plate 634 of the bucket 630. Accordingly, the slide plate 634 is moved downwardly inclined so that the chute 632 is opened to discharge the loaded rice sample into the hopper 211a of the selection unit 200.

After the discharge of the rice sample is completed as described above, the motor 621 is driven in the reverse direction and the chain 620 is rotated downward so that the bucket 630 is lowered, and thus the bucket 630 reaches its loading position. When the position sensor 651 detects this and transmits it to the computer C, the motor 621 is stopped so that the bucket 630 is positioned at the initial loading position.

The rice sample introduced into the input hopper 211a is introduced into the fixed threshing drum 212, and then the threshing protrusion 212a (alternatively arranged) is rotated by the threshing motor 214 by rotating the threshing drum 213. 213a) the rethrow is made. In this process, the diameter attached to the rice sample falls, and foreign matters such as straw are crushed into small particles.

The Jeongseon rice, which has fallen in diameter, exits to the Jeongseon rice collection space 218 formed between the threshing casing 211 and the rotation threshing drum 213 through the regular rice passing hole 212b formed on the main surface of the fixed threshing drum 212. Then, it falls into the selection casing 220 through the selection rice fall hole 215 of the lower end. On the other hand, fine foreign matter such as straw separated from the Jeongseon rice will not pass through the Jeongseon rice passage hole (212b) will remain in the foreign matter collection space 219.

At this time, the stone or sand of the size that can pass through the Jeongseon rice passing hole (212b) falls with the Jeongseon rice, this Jeongseon rice and stones and / or sand is gravity separation means 240 installed at the lower end of the Jeongseon casing 220 Will be collected separately at different locations. That is, compared to the stone or sand by the sorting wind supplied from the sorting wind supply fan 241 of the specific gravity separation means 240 installed in the lower end of the Jeongseon casing 220 in the process of falling of the rice and stone and / or sand A small specific gravity rice is pushed away beyond the separation guide plate 242, while a stone or sand with a larger specific gravity than the fine selection rice fall not close to the separation guide plate 242 but falls closer to the stone or sand It is to be separated. The separated and dropped rice in this way is discharged to the Jeongseon rice discharge chute 250 of the lower portion through the Jeongseon rice discharge port 221, the stone and / or sand is discharged to the foreign matter container 270 through the foreign matter discharge port (222). do.

On the other hand, when the separate collection of the Jeongseon rice is completed, the opening and closing cone 217 is opened to open the fine foreign matter dropping hole 216, whereby the fine foreign matter remaining in the foreign matter collection space 219 falls. At this time, since the fine foreign matters are very small in specific gravity, they are suspended in the sorting casing 220, and are sucked by the suction fan 231 of the fine foreign matter separating means 230 connected to the upper part of the sorting casing 220. Is collected. The collected fine foreign matter is collected into the foreign matter container 224 through the fine foreign matter discharge port 234 at the bottom of the cyclone dust collector 232, and the air is discharged to the outside through the air outlet 233 at the upper end thereof.

The collection action of the fine foreign matter separating means 230 is the same as for the fine foreign matters such as dust in the course of dropping the rice and stone and / or sand during threshing.

On the other hand, when the Jeongseon rice is loaded on the Jeongseon rice discharge chute 250, the meter 260 coupled to this will measure the weight of Jeongseon rice again and output the measurement signal, the weighing value of the front door 110 It is displayed on the display panel 151 and the monitor M, respectively. Subsequently, the solenoid 253 of the Jeongseon rice discharge chute 250 is operated according to the instruction of the computer C, and the chute door 254 is opened so that the Jeongseon rice is returned into the bucket 630 of the first bucket elevator 600. It is loaded and loaded.

When the selected rice in the selected rice discharge chute 250 is completely loaded in the bucket 630, the weight of the selected rice in the selected rice discharge chute 250 becomes '0', and the weight value is measured by the meter 260. The value is sent to computer C. Accordingly, the motor 621 of the first bucket elevator 600 is driven by the command of the computer C to rotate the chain 620 in the upward direction, so that the bucket 630 is the guide rail 611 of the frame 610. Will rise along.

When the rising bucket 630 reaches the second input position, that is, the installation position of the variable dog 644, the position detection sensor 652 detects this, and this detection signal is transmitted to the computer C to generate the bucket 630. The opening order of is given. Then, the solenoid 648 of the variable dog 644 is operated to rotate the dog levers 646 toward the chain 620 as shown in solid line in FIG. 16. At the same time, as the ¼ motor 621 is stopped according to the detection signal of the position detecting sensor 652, the rising bucket 630 stops at the corresponding position. 15A and 15B, the contact piece 638 formed at one end of the slide plate 634 of the bucket 630 is brought into rolling contact with the rollers 647 of the two dog levers 646. The slide plate 634 is moved downward and inclined to open the chute door 632. Then, the regular rice in the bucket 630 is introduced into the hopper 720 of the conveying means 700 located in the adjacent lower part through the outlet 631.

After the selected rice is discharged, the motor 621 is driven in the reverse direction and the bucket 630 is lowered. Accordingly, when the initial loading position is reached, the position sensor 651 detects this and stops the motor 621. As a result, the bucket 630 returns to its stowed position.

As described above, the jeongseon rice introduced into the hopper 720 of the transfer means 700 is transferred to the chute 730 at the lower end thereof through the transfer duct 710, and then the chute 730 is opened by the command of the computer C. As a result, it is introduced into the bucket 630 of the second bucket elevator 600 ′.

When the rice is completely loaded in the bucket 630 of the second bucket elevator 600 ', the bucket 630 is raised by driving the motor 621 according to the command of the computer C. When the rising bucket 630 reaches the variable dog 644 which is its first feeding position, the two dog levers 646 of the variable dog 644 are rotated by the position sensor 652 toward the chain 620, respectively. At the same time, as the motor 621 is stopped, the rising bucket 630 stops at the corresponding position. Then, the chute door 632 of the bucket 630 is opened by the rolling contact with the rollers 647 of the two dog levers 646 so that the selected rice is introduced into the input hopper 311 of the presenting unit 300.

After the selected rice is discharged, the motor 621 is driven in the reverse direction and the bucket 630 is lowered. Accordingly, when the initial loading position is reached, the position sensor 651 detects this and stops the motor 621. As a result, the bucket 630 returns to its stowed position.

Jeongseon rice introduced into the input hopper 311 is supplied to the pair of the present rollers 331, 332 of the lower portion through the feed roller 320 of the upper end of the casing casing 310, the chaff is removed and passed through them. The separated chaff is sucked by the suction fan 341 of the chaff discharge mechanism 340 and then collected by the cyclone dust collector 232 and collected into the foreign matter container 270, and brown rice discharged through the brown rice discharge port 312 It is loaded into the chute 350. And the immature is discharged through the immature discharge port 313, and is collected to the immature container 317 along the immature discharge hopper 316.

When the brown rice is completely discharged and loaded into the brown rice discharge chute 350, the brown rice discharge chute 350 is opened according to the command of the compute C to discharge brown rice into the bucket 630 of the second bucket elevator 600 ′. Let's go.

When the loading of the brown rice is completed, the second bucket elevator 600 'is operated so that the bucket 630 is lifted up to the fixed dog 641 installation position and stopped. As a result, the bucket 630 is in contact with the fixed dog 641. By opening the rice into the hopper 411 of the brown rice sorting unit 400. When the discharge of brown rice is completed, the bucket 630 is lowered to wait in the next loading position.

The brown rice introduced into the hopper 411 of the brown rice sorting unit 400 is introduced into the selected drum 420 to be separated and discharged into complete brown rice and snow brown rice by the forward and reverse rotation of the selected drum 420. That is, when brown rice is injected, the motor 430 is driven in the forward direction by the command of the computer C, and the selection drum 420 is rotated counterclockwise as shown in FIG. 9A. Then, the seolhyun rice in brown rice is discharged to the outside through the sorting hole 421 formed on the main surface of the selection drum 420 by centrifugal force, and the seolhyun rice thus removed is formed at the lower end of the casing 410. 412). At this time, since the full rice discharge port 422 of the overlapping portion is rotated in the preceding direction, the full rice does not exit to the full rice discharge port 422 but remains in the selection line 420.

The brown rice sorting process proceeds for a set time, and when the time elapses, the selection drum 420 pauses. Then, the discharge damper 414 is opened by the solenoid, and the separated snow brown rice is discharged into the lower selective discharge chute 440 through the discharge port 412.

When the snowy brown rice is completely discharged, the meter 450 coupled to the selective discharge chute 440 measures the weight of the snowy brown rice, and the measured value is displayed on the display panel 151 installed in the front door 110. It is transmitted to the computer C and displayed and stored on the monitor M. Subsequently, as shown in FIG. 18, the selective discharge chute 440 is opened by the command of the computer C, and the front door is opened through the seolhyun rice discharge guide guide 850 of the bucket conveyor 800 located below the seolhyun rice. Discharged to the brown rice discharge port 112 of the 110 is collected by the brown rice container 160. The brown rice container 160 is placed back in place after processing the brown rice.

After discharging of the brown rice is completed, the selected drum 420 which has been paused is rotated in the reverse direction (clockwise in the figure) as shown in FIG. 9B, in which case the complete brown rice discharge port 422 of the overlapping portion is Since the rotating in the trailing direction, the complete brown rice is discharged to the outside through the full brown rice outlet 422.

The complete brown rice discharge process is carried out for a set time, and when the time passes, the selected drum 420 is completely stopped, and the full brown rice is discharged through the outlet 412 by opening the discharge damper 414 at the solenoid (not shown). Is discharged into the selective discharge chute 440.

Next, the meter 450 coupled to the selective discharge chute 440 measures the weight of the whole brown rice, and the weighed value is displayed on the display panel 151 installed in the front door 110 and the computer C is used. Is transmitted to the monitor M for display.

At the same time, the motor 840 of the bucket conveyor 800 is driven in the forward direction so that the chain 833 is rotated in the counterclockwise direction, as shown in FIG. 17B, the bracket 847 is the guide rail 821 of the frame 820. To the left. Accordingly, when the sliding bucket 840 reaches the bottom of the brown rice discharge chute 440 of the brown rice sorting unit 400, the position detecting sensor 824 detects this, and the motor 834 is stopped according to the detection signal, thereby sliding the bucket. 840 is located at the bottom of the brown rice discharge chute 440.

When the sliding bucket 840 of the bucket conveyor 800 is positioned below the brown rice discharge chute 440, the selective discharge chute 440 is opened by the command of the computer C, so that the whole brown rice is discharged and the sliding bucket ( 840 is loaded and loaded.

When the complete browning of the sliding bucket 840 is completed, the motor 834 is driven in the reverse direction to rotate the chain 833 clockwise, so that the bracket 847 has a frame as shown in Fig. 17A. It is moved to the right along the guide rail 821 of 820. Subsequently, when the sliding bucket 840 reaches its discharge position, the position detection sensor 823 detects this, and the motor 834 is stopped according to the detection signal, so that the sliding bucket 840 stops the third bucket elevator 600 ″. In addition to being positioned to correspond to the bucket 630 position of the seolhyeonmi discharge guide 850 is located under the brown rice discharge chute 440.

Next, when the sliding bucket 840 is loaded with full brown rice and stopped at its discharge position, the sliding bucket 840 is opened in accordance with the instruction of the computer C, and thus the fully loaded stack as shown in FIG.

Screws 546 and 547 work with the cutting protrusions 541 on the inner surface of the cutting cylinder 540 to transfer upwards while inverting the complete brown rice. At this time, since the brown rice discharge port 544 of the upper end of the cutting cylinder 540 is pressurized by a constant pressure by the pressure adjusting damper 551 and the rate adjusting part 550, the first and second cutting screws of the cutting shaft 545 ( When the conveying pressure of the brown rice conveyed upward by 546 and 547 is lower than the pressure of the pressure adjusting damper 551, the brown rice does not escape to the brown rice discharge port 544 and is continuously inverted in the cutting cylinder 540. .

In such a state, when the conveying pressure of the brown rice by the first and second bite screws 546 and 547 of the bite shaft 545 becomes greater than the pressure of the bite pressure regulating damper 551, the brown rice is the bite pressure regulating damper. While pushing 551, it exits to the brown rice circulation space 532 through the sample outlet 544. Brown rice exited into the brown rice circulation space 532 is introduced into the milling cylinder 540 again through the brown rice inlet 543 at the bottom of the milling cylinder 540 to be inverted into white rice by repeating the above-described milling and circulation processes several times. At this time, the generated rice bran is discharged into the rice bran discharge space 533 of the casing 531 through the bran discharge holes 542 of the milling cylinder 540, and the rice bran discharge port 536 and the rice bran discharge hopper ( 572) to the rice bran 580.

Here, the cutting rate is determined by the pressure blocking the brown rice discharge port 544 of the cutting cylinder 540, it can be determined by changing the elastic force acting on the pressure adjusting damper 551.

In this case, the adjustment of the cutting rate is performed by the action of the solenoid for automatic adjustment of the first stage pressure adjustment solenoid 558a and the corresponding distance adjustment bolt 560a according to the instruction of the computer C. After applying the intermediate adjustment pressure by the action of the automatic adjustment solenoid 558b and the corresponding distance adjustment bolt 560b, finally the action of the distance adjustment bolt 560c corresponding to the three-stage adjustment of the automatic adjustment solenoid 558c To give the set pressure.

In more detail, the first stage automatic pressure solenoid 558a is operated to raise the plunger 559a, and the plunger 559a and the corresponding distance adjusting bolt 560a have a large distance. At the end of the rising of 559a, the distance adjusting bolt 560a is slightly pushed, and thus the pressure adjusting lever 555 is rotated at a small angle to press the elastic lever 553 to the pressure adjusting damper 551. The elastic force acting is set the smallest. Next, in the middle, the two-stage automatic pressure adjustment solenoid 558b is operated to rotate the plunger pressure adjusting lever 555 by raising the plunger 559b, which is the plunger 559b and the corresponding distance adjusting bolt 560b. Since a relatively small gap is formed in the liver, a larger elastic force than the initial one is set. And finally, the three-stage automatic pressure adjustment solenoid 558c is operated so that the plunger 559c is raised to rotate the pressure adjustment lever 555. Between the plunger 559c and the corresponding distance adjustment bolt 560c, Since there is almost no gap, the elastic pressure acting on the static pressure control damper 551 is set to be the largest since the static pressure control lever 555 is rotated from the beginning of the ascension.

On the other hand, in addition to the above method, the distance between each distance adjusting bolt 560a, 560b, 560c with respect to each solenoid 558a, 558b, 558c is changed or the protrusion position of the pressure adjusting bolt 557 is changed. It is also possible to adjust the cutting pressure.

As described above, the balance 510 continuously measures the weight change and transmits the weight change to the computer C. Accordingly, the computer C determines the progress of the cutting process by the weight change transmitted. On the basis of this, the step-by-step adjustment signal of the above-mentioned turning pressure is output. When the measured weight value reaches the set drawing rate, the motor is stopped by the signal of the computer C to complete the drawing. Then, the milled rice is gathered at the lower end of the brown rice circulation space 532. At this time, the computer C compares the weight value of the white rice measured by the balance 510 with the weight value of the first fully loaded rice, and monitors the cutting rate. M) and display panel 151 are respectively displayed.

Next, the power of the solenoid 539 is cut off by the computer C, and thus the white rice discharge damper 537 is opened by the restoring elasticity of the tension spring 538, so that the white rice outlet 535 of the white rice casing 531 is opened. ) Is discharged through the white rice discharge hopper 571 and re-introduced into the sliding bucket 840 of the bucket conveyor 800.

When the loading of the white rice on the sliding bucket 840 is completed, the white rice loaded by the sliding bucket 840 is opened by the instruction of the computer C to be reloaded into the bucket 630 of the third bucket elevator 600 ″. Let's go. Then, the third bucket elevator 600 ″ is operated to lift and stop the bucket 630 to the fixed dog 641 installation position. Accordingly, the bucket 630 is brought into rolling contact with the fixed dog 641 to open the white rice. It discharges into the hopper 411 of the white rice sorting unit 400 '.

Brown rice introduced into the hopper 411 of the white rice sorting unit 400 'is introduced into the selected drum 420' and is separated and discharged into complete white rice and waste by the forward and reverse rotation of the selected drum 420 '. The operation of the white rice sorting unit 400 'is performed in the same manner as the above-described brown rice sorting unit 400, and the waste and the complete white rice are sequentially discharged to the white rice discharge chute 440'.

As shown in FIG. 13, the waste and the complete white rice discharged and stacked on the white rice discharge chute 440 'are weighed by the weighing meter 450' coupled thereto, and then transferred to the computer C. And displayed on the monitor (M), it is discharged to the white rice outlet 114 of the front door 110 through the white rice discharge induction guide 460 of the lower is collected in the white rice container 170, respectively.

Next, the drawing is completed by outputting to the printer P a determination table in which the percentage of rice to be determined, the whiteness and the cutting yield, etc. are recorded according to the measured and stored data for each of the cutting steps.

In the above, the present invention has been described as collectively processing a series of milling processes through a rice sample to determine the extraction rate, the whiteness rate and the milling yield at once, but the present invention is not limited thereto, and the present invention is not limited thereto. Only bays can be determined separately.

As described above, according to the present invention, it is possible to collectively process a series of milling processes, such as net selection, rice flour, rice milling, rice milling and rice milling, by simply adding a small amount of the rice sample to be judged once. Since rice, brown rice, whole brown rice and snow brown rice, white rice, white rice and brown rice are weighed separately, the determination process can be performed automatically. The work enables you to make objective, quick and accurate decisions. In addition, since only the rice extraction rate and the whiteness rate can be determined separately as necessary, it is not necessary to separately provide the rice seeding rate and the whiteness rate determiner.

In addition, since the cutting rate can be arbitrarily selected, the cutting rate of brown rice can be determined according to the quality of the rice, and accordingly, the rice production rate can be reduced by preventing the over-cutting caused by uniform milling by adjusting the plant's rice production according to the cutting rate. Indirect production can also be planned.

In addition, the entire size of the judging machine can be miniaturized, eliminating the need for the use of large-scale milling equipment installed in the National Agricultural Products Laboratories. By judging, rice purchase can also be performed very efficiently.
