Abstract

This invention discloses a low-GI selenium-enriched rice processing equipment and process for food preparation, relating to the field of rice milling technology. The equipment includes a workbench with a milling mechanism inside for milling selenium-enriched rice of different lengths. A camera captures images of the selenium-enriched rice, allowing for real-time identification of the rice type and adjustment of milling pressure accordingly. This prevents excessive milling pressure from causing long-grain rice to break more easily. Simultaneously, while adjusting the milling pressure, a first milling roller moves a first baffle and an I-beam plate, opening a first and second water outlet. Water flows out to moisten the milled selenium-enriched rice, reducing its breakage rate. The water flow rate can be adaptively adjusted based on the milling pressure to meet the required moisture levels for different varieties of selenium-enriched rice, thus reducing the amount of broken rice.

Description

Technical Field

[0001] This invention relates to the field of rice processing technology, specifically to a low-GI selenium-enriched rice processing equipment and process for preparing food. Background Technology

[0002] Low-GI selenium-enriched rice is a functional rice variety that combines a low glycemic index with selenium enrichment. Selenium-enriched rice is produced when rice absorbs and accumulates selenium from selenium-rich soil or fertilizers during the cultivation process. Based on the source of selenium, it is divided into naturally selenium-enriched rice and artificially selenium-enriched rice. Naturally selenium-enriched rice is grown in naturally selenium-rich soil, where the selenium is primarily organic selenium, which is easily absorbed and utilized by the human body. Artificially selenium-enriched rice, on the other hand, is grown in ordinary soil by artificially increasing the selenium content through methods such as spraying selenium fertilizer or adding selenium compounds to irrigation water, allowing the rice to absorb selenium through its leaves or roots.

[0003] Low-GI selenium-enriched rice includes long-grain rice and short-grain rice. Long-grain rice is characterized by its long and thin grains, which are typically three to five times longer than it is wide. Short-grain rice is typically less than twice as long as it is wide.

[0004] To remove the husk from rice, the rice must first undergo a milling process. Existing rice milling and hulling processes typically involve two opposing rotating rubber rollers. When the rice grains enter the gap between the two rollers, they are subjected to squeezing and rubbing forces, which break the connection between the rice husk and the endosperm, causing the husk to crack and detach from the endosperm. The fallen husks and rice grains are then sieved and collected for further food processing.

[0005] Because short-grain rice grains are short and round, with a length not exceeding twice its width, they have a relatively large surface area exposed to force, allowing them to withstand relatively high milling pressure. Furthermore, they are more likely to separate the bran from the endosperm during milling. Long-grain rice grains, on the other hand, are long and thin, typically three to five times their width in length. During milling, their surface area exposed to force is relatively small. If the same milling pressure is applied as to short-grain rice, the grains may easily break during milling, affecting the integrity of the finished rice. This results in broken rice that tends to gelatinize during cooking, becoming sticky and lacking the elasticity and resilience of whole rice, leading to a poorer taste.

[0006] Therefore, it is necessary to design a low-GI selenium-enriched rice processing equipment that prevents excessive broken rice from being produced during processing. Summary of the Invention

[0018] A processing technology for a low-GI selenium-enriched rice processing device for food preparation, comprising the following steps:

[0019] S1: Pour the unhulled selenium-enriched rice into the milling mechanism and determine the length of the rice grains.

[0020] S2: Based on the length of the rice grains, the pressure regulating mechanism adjusts the appropriate pressure to grind and remove the husks from the rice. While adjusting the pressure, it also adaptively adjusts the water output to moisten the surface of the selenium-enriched rice of different lengths being ground with an appropriate amount of water.

[0021] S3: The feeding mechanism is driven by the grinding mechanism to evenly distribute the ground selenium-enriched rice above the shaking mechanism.

[0022] S4: The shaking mechanism screens the rice grains, husks, and unhulled selenium-enriched rice, and guides the unhulled selenium-enriched rice into the circulation conveyor mechanism. The circulation conveyor mechanism then transports the unhulled selenium-enriched rice back into the grinding mechanism for re-grinding.

[0023] S5: The staff pours in water and rinses the rice grains sieved by the shaking mechanism and drains the dirty water. The heating mechanism filters the dirty water and uses it. The rinsed rice grains enter the heating mechanism. At the same time, the output end of the storage tank is opened, and the fish meat pieces are transported into the heating mechanism through the spray pipe. The fish meat pieces and rice are cooked and made into seafood rice.

[0024] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0025] 1. By capturing images of selenium-enriched rice with a camera, the type of selenium-enriched rice can be determined in real time. This allows for the adjustment of appropriate grinding pressure to prevent excessive grinding pressure from causing long-grain rice to break more easily. This effectively prevents broken rice from becoming sticky and losing the elasticity and toughness of whole rice during cooking, resulting in a poor taste. Simultaneously, while adjusting the grinding pressure, the first grinding roller moves the first baffle and the I-beam plate, opening the first and second water outlets. Water flows out to moisten the milled selenium-enriched rice, reducing its breakage rate. The water flow rate can be adaptively adjusted according to the grinding pressure to meet the moisture requirements of different varieties of selenium-enriched rice, thus reducing the amount of broken rice.

[0026] 2. The rotation of the second drum not only drives the second grinding roller to grind the selenium-enriched rice, but also drives the first connecting rod to swing simultaneously. The swinging of the first connecting rod causes the sliding block to slide back and forth along the guide rod, thereby causing the discharge box to move back and forth above the perforated sieve plate. This evenly distributes the ground selenium-enriched rice above the perforated sieve plate, effectively preventing the rice from piling up in the same area and achieving a uniform distribution of the rice above the perforated sieve plate. Furthermore, this feeding mechanism requires no other drive, achieving energy savings. Attached Figure Description

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example 1, please refer to Figure 1-13 This invention provides a technical solution: a low-GI selenium-enriched rice processing device for food preparation, comprising a workbench 1, a storage tank 7 for storing fish meat scraps fixedly connected to the upper side of the workbench 1, a grinding mechanism 2 for grinding selenium-enriched rice of different lengths inside the workbench 1, a pressure regulating mechanism 3 for adjusting the grinding pressure and adaptively adjusting the water output according to the grinding pressure on one side of the grinding mechanism 2, and a device for evenly distributing the ground selenium-enriched rice onto a screening area on one side of the pressure regulating mechanism 3. The feeding mechanism 4 has a shaking mechanism 5 on its lower side for screening rice grains, husks and rice grains with husks. The grinding mechanism 2 has a circulating conveying mechanism 6 on one side for collecting unhulled selenium-enriched rice and feeding it back into the grinding mechanism 2 for grinding. The shaking mechanism 5 has a heating mechanism 8 on its lower side for heating and cooking fish meat pieces and rice. The output pipe of the heating mechanism 8 is connected to a spray pipe 9 for feeding fish meat pieces into the heating mechanism 8 and the spray pipe 9 is fixedly connected to the worktable 1.

[0050] The grinding mechanism 2 includes two first motors 22 fixedly connected to the bottom of the workbench 1. The output end of each first motor 22 is fixedly connected to a first rotating drum 21. A grinding box 27 is fixedly connected inside the workbench 1. A second rotating drum 23 is provided on both sides of the grinding box 27. The second rotating drum 23 is connected to the first rotating drum 21 by a tape. A feeding platform 25 is fixedly connected to the upper side of the grinding box 27. A guide plate 24 and a camera 26 are fixedly connected to the upper two sides of the feeding platform 25, respectively. A first pressing roller 28 and a second pressing roller 29 are provided inside the grinding box 27. Both ends of the second pressing roller 29 penetrate the grinding box 27 and are fixedly connected to the two second rotating drums 23, respectively.

[0051] The following is a supplementary explanation based on the above structure: Camera 26 is used to take pictures of the fallen selenium-enriched rice. Camera 26 has a database and a judgment module inside. The database contains identification photos of selenium-enriched rice of different lengths. After camera 26 takes an image of the surface of selenium-enriched rice, it compares it with the identification photos of selenium-enriched rice of different lengths in the internal database, identifies the length of selenium-enriched rice in advance, and classifies the length of selenium-enriched rice into two different types of selenium-enriched rice: long-grain rice and short-grain rice, based on the obtained image of the surface of selenium-enriched rice.

[0052] Selenium-enriched rice is poured into the feeding platform 25 and enters the grinding box 27. The rotation of the output end of the first motor 22 drives the first rotating drum 21 to rotate. The rotation of the first rotating drum 21 drives the second rotating drum 23 to rotate, thereby driving the second grinding roller 29 to rotate. When the selenium-enriched rice passes through the gap between the second grinding roller 29 and the first grinding roller 28, the second grinding roller 29 and the first grinding roller 28 grind the passing selenium-enriched rice. The smaller the gap, the greater the grinding pressure of the second grinding roller 29 and the first grinding roller 28 on the selenium-enriched rice.

[0053] The pressure regulating mechanism 3 includes two first hydraulic cylinders 33 fixedly connected to the upper side of the workbench 1. Each first hydraulic cylinder 33 has a slider 34 fixedly connected to its output end. One side of the slider 34 is fixedly connected to the first rolling roller 28. A U-shaped block 35 is fixedly connected to the upper side of the slider 34. The two ends of the U-shaped block 35 are the first connecting end and the second connecting end, respectively. A first guide block 31 and a second guide block 32 are respectively provided above the first rolling roller 28 and the second rolling roller 29. The first guide block 31 and the second guide block 32 are both fixedly connected to the inner wall of the grinding box 27.

[0054] The following is a supplementary explanation based on the above structure: the extension and retraction of the output end of the first hydraulic cylinder 33 is used to drive the slider 34 to move left and right, thereby driving the first crushing roller 28 to move left and right, and then driving the first crushing roller 28 to move closer to or away from the second crushing roller 29, so as to increase or decrease the crushing pressure of the second crushing roller 29 and the first crushing roller 28 on the selenium-rich rice. At the same time as the first crushing roller 28 moves, the U-shaped block 35 will also be driven to slide synchronously.

[0055] The first guide block 31 has a first cavity inside, and a first guide groove 313 is provided on the lower side of the first cavity. Several first water outlet grooves 312 are evenly provided on the lower side of the first guide groove 313. A first baffle 311 is slidably connected inside the first guide groove 313. A first clearance groove is provided on both sides of the first guide block 31. The first connecting end of the U-shaped block 35 passes through the first clearance groove and is fixedly connected to the first baffle 311.

[0056] The following is a supplementary explanation based on the above structure: the first cavity is used to place the water source. In the initial state, the output end of the first hydraulic cylinder 33 is fully extended, the second rolling roller 29 and the first rolling roller 28 are pressed against each other, and the first water outlet 312 is blocked by the first baffle 311. Therefore, the water source cannot flow out of the first water outlet 312. When the first baffle 311 slides, it blocks the first clearance groove. Therefore, the first clearance groove will not leak water.

[0057] The second guide block 32 has a second cavity inside, and a second guide groove 321 is provided on the lower side of the second cavity. Several second water outlet grooves 324 are evenly provided on the lower side of the second guide groove 321. An I-shaped plate 323 is slidably connected inside the second guide groove 321. A second clearance groove is provided on both sides of the second guide block 32. The second connecting end of the U-shaped block 35 passes through the second clearance groove and is fixedly connected to the I-shaped plate 323.

[0058] The following is a supplementary explanation based on the above structure: The second cavity is used to place the water source. In the initial state, the output end of the first hydraulic cylinder 33 is fully extended, the second rolling roller 29 and the first rolling roller 28 are pressed tightly against each other, and the I-shaped plate 323 blocks the second water outlet 324. Therefore, the water source cannot flow out of the second water outlet 324. When the I-shaped plate 323 slides, it blocks the second clearance groove. Therefore, the second clearance groove will not leak water.

[0059] When the judgment module determines that the selenium-enriched rice being fed is short-grain rice, because short-grain rice particles are shorter and rounder with higher sphericity, their contact area is relatively larger when subjected to force. The distribution of force points between rice grains and when in contact with the milling equipment is more complex, requiring greater pressure to keep the rice grains moving stably in the milling equipment to remove the bran. Therefore, the output end of the first hydraulic cylinder 33 retracts to half its stroke, and the first grinding roller 28 is driven to move to the left. At this time, the gap between the second grinding roller 29 and the first grinding roller 28 is too small, indicating that the grinding pressure is too high to accurately grind the short-grain rice. At the same time, the retraction of the output end of the first hydraulic cylinder 33 to half its stroke drives the first grinding roller 28 to move, increasing the grinding pressure. Simultaneously, the U-shaped block 35 is driven to move to the left, thereby driving the first baffle 311 and the I-shaped plate 323 to move to the left. At this time, the first water outlet 312 and the second water outlet 324 are opened halfway. A small amount of water from the first cavity and the second cavity flows out from the first water outlet 312 and the second water outlet 324 respectively, flowing into the space above the first grinding roller 28 and the second grinding roller 29. It flows downward by gravity, and in the process of flowing, it initially moistens the accumulated rice. A small amount of water that does not touch the rice will flow into the gap between the first grinding roller 28 and the second grinding roller 29. Since there is rice inside the gap for grinding, when the rice is being ground, a small amount of water just flows into the surface of the rice and moistens it a second time. Since short-grain rice has relatively weak water absorption, too much water may make it too wet and affect the grinding effect. Therefore, only a small amount of water is needed to moisten it to prevent it from breaking.

[0060] When the judgment module determines that the selenium-enriched rice being fed is long-grain rice, because long-grain rice particles are slender, they are more easily broken during milling compared to short-grain rice. If the pressure is too high, the rice grains will be subjected to excessive squeezing force during the peeling process, causing them to break, increasing the broken rice rate, and reducing the whole rice rate and the yield. Therefore, the output end of the first hydraulic cylinder 33 is completely retracted, and the first grinding roller 28 is driven to move to the left. At this time, the gap between the second grinding roller 29 and the first grinding roller 28 is too large, indicating that the milling pressure can be appropriately reduced to accurately mill the long-grain rice. At the same time as the output end of the first hydraulic cylinder 33 is completely retracted, driving the first grinding roller 28 to move and reducing the milling pressure, the U-shaped block 35 is simultaneously driven to move to the left, thereby driving the first baffle 311 and the I-shaped plate 323 to move to the left. At this time, the first water outlet trough 312 and the second water outlet trough 324 are completely closed. When the first and second cavities are opened, a large amount of water flows out from the first water outlet 312 and the second water outlet 324, respectively, and flows into the space above the first grinding roller 28 and the second grinding roller 29. It flows downward by gravity, and in the process of flowing, it initially and fully moistens the accumulated rice. Most of the water that does not touch the rice will flow into the gap between the first grinding roller 28 and the second grinding roller 29. Since the gap contains rice for grinding, most of the water just flows into the surface of the rice and fully moistens it a second time when the rice is being ground. Because long-grain rice is long and thin with a relatively large surface area and a relatively loose endosperm structure, it is easier to break during the grinding process. An appropriate amount of water can increase the toughness of the rice grains and reduce the breakage rate. Therefore, long-grain rice needs more water to be moistened.

[0061] The shaking mechanism 5 includes a support frame 51 located below the workbench 1. A second motor 52 is fixedly connected inside the support frame 51. A third rotating drum 53 is fixedly connected to the output end of the second motor 52. A connecting shaft 55 is rotatably connected to the upper side of the support frame 51. A fourth rotating drum 56 is fixedly connected to the outer side of the connecting shaft 55. The fourth rotating drum 56 and the third rotating drum 53 are connected by a tape. Turntables 54 are connected to both ends of the connecting shaft 55. A second connecting rod 57 is hinged to one side of each turntable 54. A sliding column 58 is hinged to the other end of the second connecting rod 57. A limiting groove is provided on the upper side of the support frame 51. The sliding column 58 is slidably connected to the limiting groove.

[0062] The following is a supplementary explanation based on the above structure: the rotation of the output end of the second motor 52 is used to drive the third rotating drum 53 to rotate, thereby driving the fourth rotating drum 56 to rotate, which in turn drives the turntable 54 to rotate, causing the second connecting rod 57 to move, and the sliding column 58 to slide along the limiting groove, causing the screening component 59 to sway left and right.

[0063] The upper side of the support frame 51 is provided with a screening component 59. The screening component 59 includes a U-shaped fixing plate 598 fixedly connected to the other end of the sliding column 58. A round hole screening plate 597 and a fish scale screening plate 596 are fixedly connected from top to bottom in the middle of the U-shaped fixing plate 598. A triangular slide table 595 is fixedly connected to one side of the round hole screening plate 597. A first discharge port and a second discharge port are provided on both sides of the triangular slide table 595. A rice guiding channel 593 is provided below the first discharge port, and a shell guiding channel 594 is provided below the second discharge port. A collection box 591 is fixedly connected inside the support frame 51. A partition plate 592 is fixedly connected inside the collection box 591. The rice guiding channel 593 and the shell guiding channel 594 are both fixedly connected to the inner wall of the collection box 591.

[0064] The following is a supplementary explanation based on the above structure: the round hole screening plate 597 and the fish scale screening plate 596 will be driven by the sliding column 58 to sway left and right. The round holes inside the round hole screening plate 597 can only pass through rice grains and husks. Unhulled rice grains cannot pass through because their diameter is too large.

[0065] As the round hole screening plate 597 and the fish scale screening plate 596 sway left and right, the selenium-enriched rice is crushed into rice grains, husks, and unhulled rice grains, which fall above the round hole screening plate 597. Because the round hole screening plate 597 and the fish scale screening plate 596 are evenly tilted and sway left and right, the rice grains and husks jump above the round hole screening plate 597 and fall through the screening holes to the fish scale screening plate 596. The unhulled rice grains slide down by gravity until they fall into the interior of the feed platform 63.

[0066] When the fish-scale sieve plate 596 sways left and right, the rice grains experience an inertial force related to the direction of swaying. Assuming the sieve plate 596 sways to the left, due to inertia, the rice grains will tend to move to the right relative to the sieve plate 596. Simultaneously, due to the friction between the rice grains and the sieve plate 596, there will be a frictional force (direction to the left) that opposes the rice grains' rightward movement. However, since the sieve plate 596 is tilted, the component of this frictional force perpendicular to the sieve plate 596 will affect the movement of the rice grains. Under certain conditions, this component of friction can counteract the downward component of the rice grains' gravity along the sieve plate 596, and may even cause the rice grains to tend to move upwards. Simply put, the component of friction helps the rice grains overcome the downward component of gravity along the sieve plate 596, allowing the rice grains to move upwards.

[0067] When the fish-scale sieve plate 596 shakes, the interaction between the inertial force and frictional force on the rice husk results in limited upward movement of the rice husk due to the frictional force. The downward component of gravity along the fish-scale sieve plate 596 dominates, causing the rice husk to move downward mainly under the influence of gravity. For example, assuming the coefficient of kinetic friction between the rice grain and the fish-scale sieve plate 596 is μ1 and the coefficient of kinetic friction between the rice husk and the fish-scale sieve plate 596 is μ2 (μ1>μ2), when the fish-scale sieve plate 596 shakes, the frictional force on the rice grain can generate a large upward component to overcome the component of gravity, while the upward component of friction on the rice husk is insufficient to overcome its component of gravity, so the rice husk will move downward.

[0068] The heating mechanism 8 includes an inverted cone plate 86 that runs through the bottom of the collection box 591. The inverted cone plate 86 has a water inlet and a rice inlet inside. A filter screen 87 is fixedly connected to the input end of the water inlet, a solenoid valve 84 is fixedly connected to the output end of the rice inlet, and a purifier 85 is fixedly connected to the output end of the water inlet. An electric slide rail 81 is provided on the lower side of the support frame 51. An electromagnetic heating pot 83 is fixedly connected to the sliding end of the electric slide rail 81. A pot lid 82 is provided on one side of the electromagnetic heating pot 83 and the pot lid 82 is fixedly connected to the support frame 51.

[0069] The following is a supplementary explanation based on the above structure: When a batch of rice grains has entered the inverted cone plate 86, the staff pours water into the inverted cone plate 86 to rinse the rice grains. The total amount of water poured in is the amount needed to cook a batch of rice and a batch of fish meat scraps together. After one batch of rice has finished rinsing, the input end of the purifier 85 is opened to purify the rinsing water. The filter screen 87 is used to prevent rice grains from entering the purifier 85. The purifier 85 is equipped with gauze and activated carbon. The gauze filters the rice washing water, and the activated carbon adsorbs odors, pigments, and some organic matter in the rice washing water. After the water source is purified, the purifier 85 delivers the purified water to the electromagnetic heating pot 83. The solenoid valve 84 is opened, and the washed rice grains fall down into the electromagnetic heating pot 83 in sequence. At the same time, the output end of the storage tank 7 is opened, allowing the rice grains to flow into the electromagnetic heating pot 83. The fish meat scraps inside are sequentially fed into the electromagnetic heating pot 83 through the spray pipe 9 until the rice grains are completely conveyed. The output end of the storage tank 7 is then turned off to stop the conveying. The electric slide rail 81 transports the electromagnetic heating pot 83 to the bottom of the pot lid 82. The electromagnetic heating pot 83 starts to heat the rice grains and fish meat scraps inside. Once the rice grains and fish meat scraps are cooked into seafood rice, the electric slide rail 81 transports the electromagnetic heating pot 83 to the staff. The staff then sends the cooked seafood rice to the next process for vacuum packaging. Once all the seafood rice inside the electromagnetic heating pot 83 has been conveyed, the electric slide rail 81 drives the electromagnetic heating pot 83 back to its original position, ready to heat and cook the next batch of rice grains and fish meat scraps. The sieved rice can be processed by the heating mechanism 8 to prepare it into seafood food.

[0070] The circulating conveying mechanism 6 includes an electric lifting platform 61 located on one side of the workbench 1. The lifting end of the electric lifting platform 61 is fixedly connected to a support platform 64. A second hydraulic cylinder 65 is hinged to the upper side of the support platform 64. A material discharge box 66 is hinged to the output end of the second hydraulic cylinder 65. Bearing seats 62 are provided on both sides of the material discharge box 66, and the bearing seats 62 are fixedly connected to the support platform 64. The two sides of the material discharge box 66 are rotatably connected to the bearing seats 62 through a rotating shaft. A guide platform 63 is fixedly connected to one side of the material discharge box 66, and the guide platform 63 is at an inclined angle.

[0071] The following is a supplementary explanation based on the above structure: The electric lifting platform 61 is used to move the pouring box 66 up and down. When the pouring box 66 is at the bottom, the unhulled rice grains will fall above the guide platform 63. Since the guide platform 63 is in an inclined state, the unhulled rice grains inside will slide into the pouring box 66. After all the selenium-enriched rice in a batch has been milled, the electric lifting platform 61 moves the pouring box 66 upward until the pouring box 66 reaches the top. The output end of the second hydraulic cylinder 65 extends, driving the pouring box 66 to rotate along the shaft, thereby pouring the unhulled rice grains inside the pouring box 66 back into the milling mechanism 2 for milling. After all the unhulled rice grains have been poured out, the output end of the second hydraulic cylinder 65 retracts, and the electric lifting platform 61 controls the pouring box 66 to move downward to return to its original position.

[0072] The camera 26 captures images of the selenium-enriched rice, allowing for real-time identification of the rice type. This enables the adjustment of the milling pressure to prevent excessive pressure from causing long-grain rice to break more easily. This effectively prevents broken rice from becoming sticky and losing the elasticity and resilience of whole rice during cooking, resulting in a poor taste. Simultaneously, while adjusting the milling pressure, the first milling roller 28 moves the first baffle 311 and the I-beam plate 323, opening the first and second water outlets 312 and 324. Water flows out to moisten the milled selenium-enriched rice, reducing its breakage rate. The water flow rate can be adaptively adjusted based on the milling pressure to meet the moisture requirements of different varieties of selenium-enriched rice, thus reducing the amount of broken rice.

[0073] In Example 2, after milling, most of the existing selenium-enriched rice falls into the area aligned with the conveyor for sieving, while only a small amount falls into other areas. When an area accumulates too many rice grains, husks, and unhulled rice grains, this difference in friction is masked. The lighter husks should be more easily carried to the upper area during shaking, but due to the disordered state of the accumulation, the husks may be covered by rice grains and cannot float smoothly. Alternatively, unhulled rice grains, which should be in a specific position due to frictional characteristics, are incorrectly classified into other areas due to the accumulation, resulting in a decrease in the purity of the rice grains after sieving and a poorer separation effect between unhulled rice grains and husks. Therefore, the following structure is designed to solve the above technical problems.

[0074] The feeding mechanism 4 includes second fixed blocks 45 fixedly connected to both sides of the workbench 1. A connecting block 44 is fixedly connected to one side of each second fixed block 45, and a first fixed block 42 is fixedly connected to one side of the connecting block 44. A guide rod 46 is fixedly connected between the first fixed block 42 and the second fixed block 45. A sliding block 43 is slidably connected to the outer side of the guide rod 46. A first connecting rod 41 is hinged to one side of the sliding block 43, and the other end of the first connecting rod 41 is hinged to the second rotating drum 23. The two sliding blocks 4... A discharge box 47 is fixedly connected in the middle of 3. Three discharge slots 471 are provided on the lower side of the discharge box 47, and a baffle plate 472 is fixedly connected to one side of the discharge box 47. A first feeding plate 48 is provided on the upper side of the discharge box 47, and the two sides of the first feeding plate 48 are respectively hinged to two sliding blocks 43. A second feeding plate 49 is slidably connected to the inner side wall of the first feeding plate 48. The two inner side walls of the second feeding plate 49 are hinged to the grinding box 27. The length of the first feeding plate 48 is twice the length of the second feeding plate 49.

[0075] The following is a supplementary explanation of the above structure: the baffle plate 472 is used to block the sliding selenium-enriched rice and prevent it from rushing out of the discharge box 47. When the second rotating drum 23 rotates, it drives the second grinding roller 29 to rotate, and at the same time, it also drives the first connecting rod 41 to swing. When the first connecting rod 41 swings, it drives the sliding block 43 to slide back and forth along the guide rod 46, thereby driving the discharge box 47 to move back and forth above the round hole sieve plate 597. The ground selenium-enriched rice falls from the discharge trough 471 inside the discharge box 47, and then evenly sprinkles the ground selenium-enriched rice above the round hole sieve plate 597. While the discharge box 47 moves back and forth, the first feeding plate 48 slides on the outside of the second feeding plate 49 to adaptively extend and retract, thereby conveying the ground selenium-enriched rice into the discharge box 47.

[0076] The rotation of the second drum 23 not only drives the second grinding roller 29 to grind the selenium-enriched rice, but also drives the first connecting rod 41 to swing simultaneously. As the first connecting rod 41 swings, it drives the sliding block 43 to slide back and forth along the guide rod 46, thereby causing the discharge box 47 to move back and forth above the perforated sieve plate 597. This evenly distributes the ground selenium-enriched rice above the perforated sieve plate 597, effectively preventing the selenium-enriched rice from accumulating in the same area. This achieves the effect of evenly distributing the selenium-enriched rice above the perforated sieve plate 597. Moreover, this feeding mechanism can be operated without other drives, achieving an energy-saving effect.

[0077] Example 3: A processing technology for a low-GI selenium-enriched rice processing device for food preparation. The low-GI selenium-enriched rice processing device described above includes the following steps:

[0078] S1: Pour the unhulled selenium-enriched rice into the milling mechanism 2 and determine the length of the rice grains.

[0079] S11: Camera 26 is used to take pictures of the fallen selenium-enriched rice. Camera 26 has a database and a judgment module inside. The database contains identification photos of selenium-enriched rice of different lengths. After the camera 26 takes an image of the surface of the selenium-enriched rice, it compares it with the identification photos of selenium-enriched rice of different lengths in the internal database, identifies the length of the selenium-enriched rice in advance, and classifies the length of the selenium-enriched rice into two different types of selenium-enriched rice: long-grain rice and short-grain rice, based on the obtained photos of the surface of the selenium-enriched rice.

[0080] S2: Based on the length of the rice grains, the pressure regulating mechanism 3 adjusts the appropriate pressure to grind and remove the husks from the rice. While adjusting the pressure, it also adaptively adjusts the water output to moisten the surface of the selenium-enriched rice of different lengths being ground with an appropriate amount of water.

[0081] S21: When the judgment module determines that the selenium-enriched rice being fed is short-grain rice, the output end of the first hydraulic cylinder 33 retracts to half its stroke, and the first grinding roller 28 is driven to move to the left. At this time, the gap between the second grinding roller 29 and the first grinding roller 28 is too small, indicating that the grinding pressure is too high to accurately grind the short-grain rice. Simultaneously, the retraction of the first hydraulic cylinder 33 to half its stroke moves the first grinding roller 28, increasing the grinding pressure. At the same time, the U-shaped block 35 is synchronously driven to move to the left, thereby driving the first baffle 311 and the I-beam plate 323 to move to the left. At this time, the first water outlet 3... 12 and the second water outlet 324 are opened halfway. A small amount of water from the first cavity and the second cavity flows out from the first water outlet 312 and the second water outlet 324 respectively, flowing into the space above the first grinding roller 28 and the second grinding roller 29. It flows downward by gravity, and in the process of flowing, it initially moistens the accumulated rice. A small amount of water that does not touch the rice will flow into the gap between the first grinding roller 28 and the second grinding roller 29. Since there is rice inside the gap for grinding, when the rice is being ground, a small amount of water just flows into the surface of the rice and moistens it a second time.

[0082] S22: When the judgment module determines that the selenium-enriched rice being fed is long-grain rice, the output end of the first hydraulic cylinder 33 retracts completely, and the first grinding roller 28 is driven to move to the left. At this time, the gap between the second grinding roller 29 and the first grinding roller 28 is too large, indicating that the grinding pressure can be appropriately reduced to accurately grind the long-grain rice. Simultaneously, the retraction of the output end of the first hydraulic cylinder 33 drives the first grinding roller 28 to move, reducing the grinding pressure. At the same time, the U-shaped block 35 is synchronously driven to move to the left, thereby driving the first baffle 311 and the I-beam plate 323 to move to the left. At this time, the first water outlet 312 and the second water outlet... With the water tank 324 fully opened, a large amount of water from the first cavity and the second cavity flows out from the first water outlet 312 and the second water outlet 324 respectively, flowing into the area above the first grinding roller 28 and the second grinding roller 29. The water flows downward by gravity, initially and thoroughly wetting the accumulated rice during the flow. Most of the water that does not touch the rice flows into the gap between the first grinding roller 28 and the second grinding roller 29. Since the gap contains rice for grinding, most of the water flows into the surface of the rice and thoroughly wets it a second time during the grinding process.

[0083] The shaking mechanism 5 includes a support frame 51 located below the workbench 1. A second motor 52 is fixedly connected inside the support frame 51. A third rotating drum 53 is fixedly connected to the output end of the second motor 52. A connecting shaft 55 is rotatably connected to the upper side of the support frame 51. A fourth rotating drum 56 is fixedly connected to the outer side of the connecting shaft 55. The fourth rotating drum 56 and the third rotating drum 53 are connected by a tape. Turntables 54 are connected to both ends of the connecting shaft 55. A second connecting rod 57 is hinged to one side of each turntable 54. A sliding column 58 is hinged to the other end of the second connecting rod 57. A limiting groove is provided on the upper side of the support frame 51. The sliding column 58 is slidably connected to the limiting groove.

[0084] S3: The feeding mechanism 4 is driven by the transmission of the grinding mechanism 2 to evenly scatter the ground selenium-enriched rice above the shaking mechanism 5.

[0085] S31: As the second rotating drum 23 rotates, it drives the second grinding roller 29 to rotate, and at the same time, it drives the first connecting rod 41 to swing. As the first connecting rod 41 swings, it drives the sliding block 43 to slide back and forth along the guide rod 46, thereby driving the discharge box 47 to move back and forth above the round hole sieve plate 597. The ground selenium-enriched rice falls from the discharge trough 471 inside the discharge box 47, and then evenly sprinkles the ground selenium-enriched rice above the round hole sieve plate 597. While the discharge box 47 moves back and forth, the first feeding plate 48 slides on the outside of the second feeding plate 49 to adaptively extend and retract, thereby conveying the ground selenium-enriched rice into the interior of the discharge box 47.

[0086] S4: The shaking mechanism 5 screens the rice grains, husks and unhulled selenium-enriched rice, and guides the unhulled selenium-enriched rice into the circulation conveying mechanism 6. The circulation conveying mechanism 6 then transports the unhulled selenium-enriched rice back into the grinding mechanism 2 for re-grinding.

[0087] S41: During the left-right shaking of the round hole screening plate 597 and the fish scale screening plate 596, the selenium-enriched rice is crushed into rice grains, husks and unhulled rice grains, which fall above the round hole screening plate 597. Due to the uniform tilt and left-right shaking of the round hole screening plate 597 and the fish scale screening plate 596, the rice grains and husks jump above the round hole screening plate 597 and fall through the screening holes to the top of the fish scale screening plate 596, while the unhulled rice grains slide down by gravity until they fall into the interior of the guide platform 63.

[0088] S42: When the fish-scale sieve plate 596 sways left and right, the rice grains will be subjected to an inertial force related to the direction of swaying. Assuming the fish-scale sieve plate 596 sways to the left, due to inertia, the rice grains will tend to move to the right relative to the fish-scale sieve plate 596. At the same time, due to the friction between the rice grains and the fish-scale sieve plate 596, there will be a frictional force (direction to the left) that opposes the rightward movement of the rice grains. However, since the fish-scale sieve plate 596 is inclined, the component of this frictional force perpendicular to the fish-scale sieve plate 596 will affect the movement of the rice grains. Under certain conditions, this component of the frictional force can counteract the downward component of the rice grains' gravity along the fish-scale sieve plate 596, and may even cause the rice grains to tend to move upward. Simply put, the component of the frictional force helps the rice grains overcome the downward component of gravity along the fish-scale sieve plate 596, allowing the rice grains to move upward.

[0089] S43: When the fish-scale sieve plate 596 shakes, under the interaction of the inertial force and friction force on the rice husk, the friction force has a limited effect on the upward movement of the rice husk. The downward component of gravity along the fish-scale sieve plate 596 is dominant, so the rice husk is mainly affected by gravity and moves downward. For example, assuming that the coefficient of kinetic friction between the rice grain and the fish-scale sieve plate 596 is μ1 and the coefficient of kinetic friction between the rice husk and the fish-scale sieve plate 596 is μ2 (μ1>μ2), when the fish-scale sieve plate 596 shakes, the friction force on the rice grain can generate a large upward component force to overcome the component force of gravity, while the upward component force generated by the friction force on the rice husk is insufficient to overcome its component force of gravity, so the rice husk will move downward.

[0090] S5: The staff pours in water and washes the rice grains sieved by the shaking mechanism (5) and drains the dirty water. The heating mechanism (8) filters the dirty water and uses it. The washed rice grains enter the heating mechanism (8). At the same time, the output end of the storage tank (7) is opened and the fish meat pieces are transported into the heating mechanism (8) through the spray pipe (9). The fish meat pieces and rice are cooked to make seafood rice.

7. A processing method for a low-GI selenium-enriched rice processing device for food preparation, using the low-GI selenium-enriched rice processing device for food preparation as described in any one of claims 1-6, characterized in that, Includes the following steps: S1: Pour the unhulled selenium-enriched rice into the milling mechanism (2) and determine the length of the rice grains; S2: According to the length of the rice grains, the pressure regulating mechanism (3) adjusts the appropriate pressure to grind and remove the husks from the rice, and while adjusting the pressure, it adaptively adjusts the water output to wet the surface of the selenium-rich rice of different lengths being ground with an appropriate amount of water. S3: The feeding mechanism (4) is driven by the transmission of the grinding mechanism (2) to evenly spread the ground selenium-enriched rice above the shaking mechanism (5). S4: The shaking mechanism (5) screens the rice grains, husks and unhulled selenium-enriched rice, and introduces the unhulled selenium-enriched rice into the circulation conveying mechanism (6). The circulation conveying mechanism (6) then transports the unhulled selenium-enriched rice back into the grinding mechanism (2) for grinding again. S5: The staff pours in water and washes the rice grains sieved by the shaking mechanism (5) and drains the dirty water. The heating mechanism (8) filters the dirty water and uses it. The washed rice grains enter the heating mechanism (8). At the same time, the output end of the storage tank (7) is opened and the fish meat pieces are transported into the heating mechanism (8) through the spray pipe (9). The fish meat pieces and rice are cooked and made into seafood rice.
