Rice quality automatic detection system

The invention relates to the quality analysis of rice, in particular to an automatic rice quality detection system which can quickly obtain the ratio of white rice in rice to provide quantitative indicators of rice quality.

After the harvest, the rice needs to be exposed to the sun or dried to remove the water before the farmers sell it to the rice purchaser.

For rice buyers, the rice may be mixed with unwanted materials such as sand, stone, and broken leaves, and he also needs to go through the rice milling process to convert the rice into white rice, which can be further sold to the end market. Therefore, when acquiring rice, the rice channel supplier must further evaluate the proportion of white rice that can be obtained to determine the purchase price.

As far as the existing rice milling equipment and rice acquisition model are concerned, the rice purchasers have placed the purchased rice in a large storage tank of the rice milling equipment, and only once milled all the white rice, it is difficult for the rice purchaser to confirm successively. The quality of the rice for each acquisition.

The traditional pre-assessment method is usually based on the finished product conversion table provided by the agricultural unit, and the white rice ratio is first evaluated. However, as mentioned above, rice may be mixed with unwanted substances such as sand, stone, and broken leaves, and the rice may vary greatly depending on the origin, climate, and irrigation conditions, resulting in a significant difference between the results obtained from the finished product conversion table and the actual conditions. Therefore, the rice purchaser must rely on personal experience to correct the results of the finished product conversion table, but this also caused the divergence of the purchase price at the time of the acquisition, resulting in a conflict between the buyer and the farmer. Therefore, for rice buyers or rural economic units, it is necessary to have a device that can quickly and correctly analyze the quality of rice to solve the bargaining problem during rice purchase.

In view of the above problems, the present invention provides an automatic detection system for rice quality, which can quickly analyze the proportion of first-class white rice that can be obtained in rice, and form a quantitative index to quickly confirm the quality of rice and solve the problem that rice quality is difficult to confirm.

In order to achieve the above object, the present invention provides an automatic rice quality detection system for analyzing the amount of white rice produced by rice, including: a volumetric weight measuring device for taking a certain amount of rice, and measuring the basis weight thereof. In order to obtain the weight of rice; a glutinous rice machine for separating rough rice and rice bran from rice to obtain white rice; a first weight measuring device for measuring coarse weight; a second weighing device, It is used to measure the weight of rice bran; a vibrating sieve rice machine is used to screen white rice as first-class white rice, large broken rice and small broken rice; a third weight measuring device is used to measure first-class white rice weight; a heavy device for measuring the weight of the large broken rice; a fifth weighing device for measuring the weight of the small broken rice; a controller for controlling the operation and stopping of the Shimijing rice machine, and receiving the first weight measuring device, The weight data measured by the second weight measuring device, the third weight measuring device, the fourth weight measuring device and the fifth weight measuring device; the weight of the brown rice is obtained by subtracting the weight from the basis weight; the weight of the brown rice is reduced by the weight of the rice Obtain white rice weight; and analyze the weight, coarse weight, brown rice weight, rice bran weight A large proportion of broken rice, broken rice and small weight of the first-class rice, rice made quantitative indicators of quality.

The effect of the invention is that, through the detection procedure of the invention, various quantitative indicators can be quickly obtained for the operator to quickly analyze the quality of the rice and solve the problem of rice quality assessment.

Please refer to FIG. 1 and FIG. 2 for a top view of the rice quality automatic detection system according to the first embodiment of the present invention for analyzing the white rice weight produced by the rice. The rice quality automatic detection system of the present invention comprises a controller 10, a volumetric weight measuring device 11, a glutinous rice machine 80, a first buffer device 31, a second buffer device 32, and a first weight measuring device 51.

The weight measuring device 11, the first weight measuring device 51, and the second weighing device 52 are also electrically connected to the controller 10 to transmit the measured weight data to the controller 10.

As shown in Fig. 1, the volumetric measuring device 11 is used to take a certain amount of rice and measure its basis weight to obtain the weight of the rice. The volumetric weight measuring device 11 includes a container 11a and a base weight measuring device 11b. The container 11a has a fixed capacity; the rice is filled with the container 11a, or is fixed to a certain scale of the container 11a to obtain a certain volume (volume) of rice before each test, for example, a paddle having a capacity of 3 liters per take. The base weight measuring device 11b is used to measure the basis weight W _total of rice having a certain volume (volume). This basis weight W _total (for example, 3 kg) is divided by the aforementioned certain volume (volume), that is, the volume of the rice per unit volume.

As shown in Figure 2, the Shibuya Rice Mill 80 is used to inject rice and separate the rough rice and rice bran from the rice with white rice. The Shibuya rice machine 80 includes a glutinous rice machine 20 and a rice machine 40.

As shown in "Fig. 2", the top mask of the Shibuya machine 20 has a rice injection port 21 for injecting rice into the Shibuya machine 20. The glutinous rice machine 20 is used to separate the rough husk (rice husk) from the rice to obtain brown rice. Before the rice is injected into the glutinous rice machine 20, the rice is first weighed by the capacity measuring device 11 to obtain its basis weight and measure its capacity. The rough enthalpy separated by the smashing machine 20 is obtained by measuring the weight through the first weight measuring device 51 to obtain the rough weight W _coarse .

By subtracting the coarse weight W _{coarse from the} basis weight W _total , the brown rice weight W1 at this stage can be obtained, and the weight of the brown rice is not separately required to simplify the internal structure of the automatic rice quality detection system.

As shown in "Fig. 2", the side of the grain dryer 20 has a brown rice outlet 22 for allowing the brown rice to leave the basket machine 20. The blower 81 is connected to the squaring machine 20 to inject a flow of air into the squaring machine 20 to generate wind power to take the rough or poorly growing empty rice husk in the gluten machine 20 from the gluten machine 20 and send it to the first A weight measuring device 51 measures the weight to separate the brown rice and the rough, and obtains the coarse weight W _coarse and reversely pushes to obtain the brown rice weight W1.

As shown in Fig. 2, the first cushioning device 31 is provided corresponding to the brown rice outlet 22 for temporarily holding the brown rice, and waiting for the operation of the grain dryer 20 to end, the first cushioning device 31 may be substantially a container.

As shown in "Fig. 2", the top mask of the polished rice machine 40 has a brown rice injection port 41 for injecting brown rice into the rice mill 40. The rice mill 40 is used to further finish the brown rice to separate the rice bran from the brown rice to obtain white rice. The rice mill 40 is also connected to a blower 82 for injecting air into the rice mill 40 to generate wind to carry the rice bran away from the rice mill 40. The rice bran is taken to the second weight measuring device 52 to measure the weight of the _{rice bran} . The weight of the brown rice W1 minus the rice bran weight W _{m 糠} , you can get the white rice weight W2 at this stage, do not need to take the weight of the individual white rice to simplify the internal structure of the automatic detection system of rice quality.

As shown in "Fig. 2", the side of the polished rice machine 40 has a white rice output port 42. When the white rice is separated from the rice bran, the rice bran is taken away by the airflow and sent to the second weighing device 52 to take the weight, and then Get the rice bran weight W _{m 糠} while pushing the white rice weight W2. The white rice then moves to the white rice outlet 42 and leaves the rice mill 40.

The second buffer device 32 is disposed corresponding to the white rice output port 42 for temporarily holding the white rice, waiting for the complete operation of the rice mill 40, and the second buffer device 32 may be substantially a container.

The white rice obtained in the second buffer device 32 includes white rice having a substantially complete shape, large broken rice having a slightly larger particle size, and small white rice, large broken rice and small broken rice having a small particle size. The biggest difference is the difference in average particle size. Therefore, first-class white rice, large broken rice and small broken rice can be screened by the mesh size change of the screen 71.

After the white rice weight is obtained, the controller 10 issues a control command to the conveying device 60, causes the conveying device 60 to move the second buffer device 32 to the vibrating screen rice machine 70, and injects the white rice into the vibrating screen rice machine 70.

Referring to the "Fig. 3", the vibrating screen rice machine 70 includes at least one screen 71, and continuously generates vibration by a vibrating source 72, so that the white rice continues to move on the screen 71 to screen the white rice as a first-class white rice. Large broken rice and small broken rice.

In order to understand the broken state of the rice grains, the number of the screens 71 may be plural, for example, two screens 71. The mesh size of the screen 71 located at the uppermost layer is slightly smaller than the particle size of the first white rice, and the mesh of the lower mesh 71 is larger than the mesh 71 of the upper layer. The vibrating screen rice machine 70 is placed obliquely to the ground, and the white rice is placed at the higher end. After the vibration source 72 continues to vibrate, the white rice continues to move on the uppermost screen 71. At this time, the large broken rice and the small broken rice will pass through the uppermost screen 71 and fall to the lower screen 71. The small broken rice which is more severely broken is further passed through the sieve hole of the lower sieve 71, falls to the bottom, and the large broken rice is left on the lower sieve 71.

Finally, with the vibration generated by the vibration source 72, the first white rice, the large broken rice, and the small broken rice respectively leave the vibrating screen rice machine 70, and fall into the third buffer device 33 (contains a white rice) and the fourth buffer. The device 34 (contains large broken rice) and the fifth buffer device 35 (supports small broken rice). After the third weight measuring device 53, the fourth weight measuring device 54, and the fifth weight measuring device 55 measure the total weight of the third buffering device 33, the fourth buffering device 34, and the fifth buffering device 35, the data can be transmitted. To the controller 10, for the controller 10 to deduct the empty weight of each buffer device, the first white rice weight W is _completed , the large broken rice weight W is _large , and the small broken rice weight W is _small .

Finally, based on the weight data measured by the first weight measuring device 51, the second weight measuring device 52, the third weight measuring device 53, the fourth weight measuring device 54, and the fifth weight measuring device 55, the controller 10 calculates according to the following formula The proportion of each parameter is used as a data indicator of rice quality:

The basis weight W _total = weight W _Ends First rice Cardamine large weight W + + small _{large small} Cardamine weight W + W heavy _bran rice hull + W heavy _crude

Referring to "Fig. 2", "Fig. 4" and "Fig. 5", the operation mode of the rice quality automatic detection system of the present invention and the automatic detection method of the rice quality proposed by the present invention will be described.

Step Step 1, firstly, a certain volume (volume) of rice is taken in a container 11a having a fixed capacity, and the basis weight W _{total of the} rice is measured by the base weight measuring device 11b, and the controller 10 is input to the controller 10 to make the controller 10 according to the rice.

Take away from the Shibuya machine 20.

Step Step 4, in order to ensure that the rice can completely pass the rice milling process and avoid the idling of the glutinous rice machine 20, the controller 10 can set the glutinous rice running time according to the amount of rice. For example, in 30 seconds, after the controller 10 starts the operation of the masher machine 20 for 30 seconds, the operation of the hopper machine 20 and the blower 81 is stopped. During the timekeeping process, the controller 10 can continuously display the countdown time of the operation time of the glutinous rice machine 20 through the human machine interface 90, so that the user can understand whether the operation time of the Shibuya is sufficient.

Step 5: After the operation time of the Shibuya, the brown rice is also separated from the rice machine 20 by the brown rice outlet 22 and enters the first buffer device 31. At this time, the controller 10 sends a repeat request signal to a first measurement means 51, a weight data is read by the first weighing device 51 as the weight W _crude hull 10 back to the controller.

Step Step 51, the controller 10 W _total basis weight minus the weight W _thick hull, made of brown rice weight W1. The weight of brown rice is reduced by rice to obtain coarse and heavy weight. After obtaining the aforementioned data, the controller 10 can display the brown rice weight and the rough weight through the human machine interface 90.

Step Step 8, in order to ensure that the brown rice can be completely subjected to the finishing process and the rice mill 40 is prevented from idling, the controller 10 sets the running time of the polished rice according to the weight of the rice or the weight of the brown rice. For example, in 30 seconds, after the controller 10 starts the operation of the rice mill 40 for 30 seconds, the operation of the rice mill 40 and the blower 82 is stopped. During the timekeeping process, the controller 10 program displays the countdown of the running time of the rice miller 40 through the human machine interface 90, so that the user can understand whether the running time of the polished rice is sufficient or too long.

Step Step 9, after the polished rice running time is over, the white rice leaves the polished rice machine 40 from the white rice output port 42 and enters the second weighing device 52. At this time, the controller 10 sends a request signal to the second weighing device 52, and the second weighing device 52 reads the amount of the _{meter and transfers it} back to the controller 10.

Step Step 91, the controller 10 brown rice bran heavy weight W1 minus W _bran, you can get this phase W2 heavy rice, the controller 10 may display the weight W2 rice _bran and rice bran weight W through the man-machine interface 90.

Step Step 10. The controller 10 then outputs a control command to the transfer device 60, which controls the transfer device 60 to move the second buffer device 32 to the shake screen rice machine 70 and inject the white rice into the shake screen rice machine 70.

Step Step 11, the controller 10 outputs a control command again, starts the vibrating screen rice machine 70, and causes the vibrating screen rice machine 70 to screen the white rice, and screens the white rice into a first-class white rice, a large broken rice, and a small broken rice. The three buffering device 33 and the fourth buffering device 34 are provided with one white rice, large broken rice and small broken rice.

In fact, in order to understand the broken state of the rice grains, the broken rice can be further screened into large broken rice having a larger particle size and small broken rice having a smaller particle diameter, and are respectively supported by the fourth buffer device 34 and the fifth buffer device 35. Large broken rice and small broken rice.

Step 12, the controller 10 then outputs the request signal to the third weight measuring device 53 and the fourth weight measuring device 54 to obtain the first white rice weight and the broken rice weight. After obtaining the foregoing data, the controller 10 can display the first white rice weight and the broken rice weight through the human machine interface 90.

As described above, when the broken rice is further screened into large broken rice and small broken rice, the controller 10 outputs the request signal to the third weighing device 53, the fourth weighing device 54, and the fifth weighing device 55 respectively. First rice heavy _finish W, W _large heavy large broken rice, broken rice small _little weight W, and displayed in human-machine interface 90 first-class rice weight W _End, large heavy broken rice W _large and small broken weight W _smaller.
