Description

Technical Field

[0001] This invention relates to the field of legume seed processing technology, specifically to a device for separating the outer layer and cotyledons of legume seeds. Background Technology

[0002] Legumes refer to the seeds of leguminous plants, including soybeans, broad beans, peas, mung beans, kidney beans, and adzuki beans. Soybeans are classified by color into yellow soybeans, black soybeans, and green soybeans. Kidney beans can be further divided into flat beans, green beans, sword beans, string beans, and cowpeas. Adzuki beans come in colors such as red, yellow, light green, gray, white, and brown. During soybean production and processing, soybeans contain approximately 8% skin, which is rich in cellulose, pigments, pectin, and waxes. Separating the soybean skin from the cotyledons can increase the protein content of soybean meal and the throughput of the extractor, thereby improving the utilization rate and yield of soybean protein. Soybean skin can be developed and utilized separately; selling soybean skin can offset the electricity consumption during skinning, increase the throughput of subsequent equipment by 6%-7%, reduce energy consumption during soybean product processing, and reduce equipment wear.

[0003] In existing technologies, common dehulling methods for legumes include hot dehulling, warm dehulling, and cold dehulling. Warm dehulling of common soybeans results in incomplete dehulling. While low-temperature methods for black soybeans can protect anthocyanins in the skin, they are unsuitable for soybeans due to high production costs. Hot dehulling for soybeans is cheaper than warm dehulling and improves the dehulling rate, but it leads to higher bean breakage and significant loss of soybean protein during soy product production. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for separating the outer layer and cotyledons of legume seeds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for separating the outer layer and cotyledons of legume seeds includes a microwave heating device and a mounting frame. The microwave heating device is mounted on the top of the mounting frame, and sealing plates are slidably mounted on both ends of the microwave heating device. A conveyor belt is mounted inside the mounting frame via multiple support shafts. Multiple placement boxes for placing legume seeds are mounted on the surface of the conveyor belts. Each placement box is equipped with a turning mechanism to drive the legume seeds to turn. Two fixed frames are mounted on the top of the mounting frame, and a drive mechanism for driving the turning mechanism is mounted at the bottom of the two fixed frames. A separation box for separating the outer layer and cotyledons of legume seeds is mounted at one end of the mounting frame, and an automatic separation mechanism is installed inside the separation box.

[0007] Optionally, the flipping mechanism includes a rotating plate rotatably installed inside the placement box, with elastic plates installed at the four bottom corners of the rotating plate, and multiple first through slots opened inside the rotating plate.

[0008] Optionally, rectangular slots are provided at both ends of the rotating plate, and telescopic plates are installed inside the two rectangular slots. The two telescopic plates are connected to the inner wall of one side of the rectangular slot through multiple elastic elements.

[0009] Optionally, a cover plate is rotatably mounted on the top of the placement box, a limiting plate for limiting the rotation angle of the cover plate is mounted on one side of the outer wall of the placement box, and a discharge port is opened on the side of the outer wall of the placement box near the limiting plate, and a sealing plate is rotatably mounted inside the discharge port.

[0010] Optionally, the cover plate has multiple second through slots inside, and three of the second through slots are slidably installed with moving rods inside, with the bottom ends of the multiple moving rods passing through the second through slots and fitted with flipping frames.

[0011] Optionally, a connecting plate is installed at the top of the multiple movable rods, and a connecting groove is provided on the top of the connecting plate.

[0012] Optionally, the drive mechanism includes slide grooves opened at the bottom of two fixed frames, two sliders installed inside each slide groove, a first electric telescopic rod installed at the bottom end of each slider, a pressing plate installed at the telescopic ends of the two cooperating first electric telescopic rods, and multiple connecting blocks installed at the bottom of the pressing plate.

[0013] Optionally, two second electric telescopic rods are installed on both outer walls of the mounting frame, and the telescopic ends of the two second electric telescopic rods are connected to the outer wall of the separation box.

[0014] Optionally, the automatic separation mechanism includes two rubber rollers rotatably installed inside the separation box. A drive motor is installed on one outer wall of the separation box. The output end of the drive motor is connected to the rotating part of one of the rubber rollers. A first gear is rotatably installed on the outer wall of the separation box near the drive motor. The outer wall of the output end of the drive motor is rotatably engaged with the rotating part of the first gear via a belt. A second gear is installed on one rotating part of the other rubber roller. The first gear and the second gear mesh.

[0015] Optionally, the separation box is installed at an angle below the two rubber rollers with a filter plate. A collection box is installed at the higher end of the separation box near the filter plate, and a collection bag is installed at the bottom of the collection box. A blower is installed at the lower end of the separation box near the filter plate, and a gap is left between the lower end of the filter plate and the separation box.

[0016] The beneficial effects of this invention are:

[0017] 1. In this invention, by using a microwave heating device and a separation box, the outer skin and cotyledons of bean seeds can be automatically separated by microwave peeling. The bean seeds are heated in a short time with extremely high efficiency, and the outer skin of the bean seeds can be broken quickly. Furthermore, by using a turning mechanism, the bean seeds can be turned over during the intermittent heating process of the microwave heating device, so that the microwave heating device can heat the bean seeds more evenly, further improving the efficiency of bean seed heating and subsequent separation of outer skin and cotyledons.

[0018] 2. In this invention, to improve the turning effect of the bean seeds on the top of the rotating plate, the extension ends of multiple first electric telescopic rods are controlled to drive two pressing plates to press down, while the multiple connecting blocks at the bottom of the two pressing plates are respectively inserted and engaged with the corresponding connecting slots. As the two sliders are controlled to move, the two pressing plates and multiple connecting plates move together in the direction of approaching and moving away from each other, thereby driving the two turning frames to turn the bean seeds back and forth on the top of the corresponding rotating plate, further improving the turning effect of the bean seeds, ensuring that the subsequent microwave heating equipment can uniformly heat the bean seeds inside the placement box, and ensuring the automatic separation effect of the bean seed skin and cotyledons.

[0019] 3. In this invention, after the microwave heating device heats the beans inside the placement box, as the conveyor belt continues to rotate, it drives the placement box from above to below the conveyor belt. At this time, the end of the cover plate away from the placement box comes into contact with the top opening of the separation box. The heated beans inside the rotating plate will slide down to the surface of the cover plate and enter the interior of the separation box. While the beans are moving on the surface of the cover plate, some of the skin layer on the surface of the beans will automatically rub off and fall down from multiple second channels, so that the skin layer is automatically removed, avoiding further processing.

Detailed Implementation

[0033] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0034] Reference Figures 1-11A device for separating the outer layer and cotyledons of legume seeds includes a microwave heating device 1 and a mounting frame 3. The microwave heating device 1 is mounted on top of the mounting frame 3. Sealing plates 2 are slidably mounted at both ends of the microwave heating device 1. A conveyor belt 4 is mounted inside the mounting frame 3 via multiple support shafts. Multiple placement boxes 5 for placing legume seeds are mounted on the surface of the conveyor belt 4. Each placement box 5 has a turning mechanism inside to drive the legume seeds to turn. Two fixed frames 6 are mounted on the top of the mounting frame 3. A drive mechanism for operating the turning mechanism is located at the bottom of the two fixed frames 6. A separation box 9 for separating the outer layer and cotyledons of legume seeds is located at one end of the mounting frame 3. An automatic separation mechanism is installed inside the separation box 9. By setting sealing plates 2 at the inlet and outlet of the microwave heating device 1 at both ends, after the conveyor belt 4 carries the multiple placement boxes 5 into the microwave heating device 1, the two sealing plates 2 are controlled to slide downwards to seal the inlet and outlet, preventing microwave leakage from inside the microwave heating device 1.

[0035] As a technical optimization of the present invention, the flipping mechanism includes a rotating plate 26 rotatably installed inside the placement box 5. Elastic plates 27 are installed at the four corners of the bottom of the rotating plate 26, and multiple first through slots 25 are formed inside the rotating plate 26. The elastic plates 27 are made of elastic plastic or other non-metallic materials, providing support and fixing the rotating plate 26 in a horizontal state inside the placement box 5. After pressing down on one end of the rotating plate 26, deformation occurs through the corresponding two elastic plates 27 below, allowing one end of the rotating plate 26 to rotate downwards, thus causing the bean seeds on the top of the rotating plate 26 to move synchronously.

[0036] As a technical optimization of the present invention, rectangular slots are provided at both ends of the rotating plate 26, and telescopic plates 28 are installed inside the two rectangular slots. The two telescopic plates 28 are connected to the inner wall of one side of the rectangular slot through multiple elastic elements 29. Since there will be a gap between one end of the rotating plate 26 and the inner wall of the placement box 5 after it rotates downward, the telescopic plates 28 provided at both ends of the rotating plate 26 can be used to retract the telescopic plates 28 when the rotating plate 26 is in a horizontal state. When the rotating plate 26 rotates, the telescopic plates 28 can extend outward a certain distance to fill the gap generated by the rotation, preventing the bean seeds on the top of the rotating plate 26 from falling down through the gap.

[0037] As a technical optimization of the present invention, a cover plate 19 is rotatably installed on the top of the placement box 5, and a limiting plate 20 for limiting the rotation angle of the cover plate 19 is installed on one side of the outer wall of the placement box 5. A discharge port is opened on the side of the outer wall of the placement box 5 near the limiting plate 20, and a sealing plate 18 is rotatably installed inside the discharge port. Since multiple first through grooves 25 are opened inside the rotating plate 26, after the bean seeds are heated by the microwave heating device 1, there will be gaps between the skin layer on the surface of the seeds and the cotyledons, so that some of the skin layer will automatically fall off and pass down through the first through grooves 25 to fall into the inner bottom surface of the placement box 5 for temporary storage. As the conveyor belt 4 continues to rotate, it can drive the placement box 5 to rotate downward, so that the sealing plate 18 will automatically rotate downward and open, pouring out the small amount of skin layer collected inside.

[0038] As a technical optimization of the present invention, the cover plate 19 has multiple second through slots inside, and a moving rod 23 is slidably installed inside three of the second through slots. The bottom ends of the multiple moving rods 23 pass through the second through slots and are fitted with a flipping frame 24. By moving the moving rods 23 back and forth inside three of the second through slots, the flipping frame 24 can be driven to simultaneously flip the beans on the top of the rotating plate 26, so as to facilitate the microwave heating device 1 to fully heat them.

[0039] As a technical optimization of the present invention, a connecting plate 21 is installed on the top of multiple moving rods 23, and a connecting groove 22 is opened on the top of the connecting plate 21. By controlling the connecting plate 21 to move back and forth on the top of the cover plate 19, the multiple moving rods 23 and the flipping frame 24 can be moved synchronously.

[0040] As a technical optimization of the present invention, the driving mechanism includes slide grooves 14 opened at the bottom of two fixed frames 6. Two sliders 17 are installed inside each of the two slide grooves 14. A first electric telescopic rod 15 is installed at the bottom end of each slider 17. A pressing plate 7 is installed at the telescopic ends of the two cooperating first electric telescopic rods 15. Multiple connecting blocks 16 are installed at the bottom of the pressing plate 7. Double-ended screws are pre-installed inside each of the two slide grooves 14. The two sliders 17 respectively cooperate with the outer walls of their corresponding double-ended screws. A driving device is installed at one end of each double-ended screw. While the driving device rotates the double-ended screws, it also drives the two sliders 17 to move back and forth within their respective slide grooves 14; thereby driving the first electric telescopic rods 15 and the pressing plate 7 below to move and adjust.

[0041] As a technical optimization of the present invention, two second electric telescopic rods 8 are installed on both outer walls of the mounting frame 3, and the telescopic ends of the two second electric telescopic rods 8 are connected to the outer wall of the separation box 9. By controlling the extension and retraction of the telescopic ends of the multiple second electric telescopic rods 8, the distance between the separation box 9 and the conveyor belt 4 is automatically adjusted to ensure that the bean seeds after heat treatment inside the placement box 5 can fall smoothly into the separation box 9.

[0042] As an optimized technical solution of the present invention, the automatic separation mechanism includes two rubber rollers 30 rotatably installed inside a separation box 9. A drive motor 13 is installed on one outer wall of the separation box 9, and the output end of the drive motor 13 is connected to the rotating part of one of the rubber rollers 30. A first gear 33 is rotatably installed on the outer wall of the separation box 9 near the drive motor 13. The outer wall of the output end of the drive motor 13 is rotatably engaged with the rotating part of the first gear 33 via a belt 32. A second gear 34 is installed on one rotating part of the other rubber roller 30, and the first gear 33 and the second gear 34 mesh. The drive motor 13 can directly drive one of the rubber rollers 30 to rotate, and with the help of the belt 32, the first gear 33 and the second gear 34, the other rubber roller 30 can be driven to rotate synchronously in the opposite direction. This allows the two cooperating rubber rollers 30 to squeeze and rub the heated bean kernels, causing the outer skin and cotyledons of the bean kernels to be automatically separated.

[0043] As a technical optimization of the present invention, a filter plate 31 is installed at an angle below the two rubber rollers 30 in a separation box 9. A collection box 10 is installed at the higher end of the separation box 9 near the filter plate 31, and a collection bag 11 is installed at the bottom of the collection box 10. A blower head 12 is installed at the lower end of the separation box 9 near the filter plate 31, and a gap is left between the lower end of the filter plate 31 and the separation box 9. In actual use, the blower head 12 is connected to the output end of an externally preset fan, so that the blower head 12 can blow air onto the surface of the filter plate 31 to separate the skin layer and cotyledons that have fallen on the top of the filter plate 31 after being rubbed. The lighter skin layer is blown into the interior of the collection box 10 and enters the collection bag 11 for collection and storage, while the heavier cotyledons are discharged downward through the gap at the lower end of the filter plate 31 into the preset collection container below for collection.

[0044] In this invention, when the user uses the device, such as Figure 1As shown, the surface of the conveyor belt 4 is provided with two sets of placement boxes 5, four in each set, located on the upper and lower sides of the conveyor belt 4 respectively. After one set of placement boxes 5 rotates to the bottom of the two fixed frames 6, the cover plate 19 is opened upwards, and an appropriate amount of bean seeds are placed into the four placement boxes 5 in sequence, so that the bean seeds inside the placement boxes 5 are located at the top of the horizontal rotating plate 26. Then the cover plate 19 is rotated downwards to reset. As the conveyor belt 4 continues to rotate, the four placement boxes 5 are driven into the microwave heating device 1, and the two sealing plates 2 are controlled to slide downwards to seal the inlet and outlet of the microwave heating device 1 at both ends. This allows the microwaves generated inside the microwave heating device 1 to heat and expand the skin of the bean seeds, creating tiny gaps between the skin and the cotyledons.

[0045] Because the top of the placement box 5 is provided with a cover plate 19, it can prevent some of the bean seeds from expanding due to heat after being microwaved and splashing out into the microwave heating device 1. Furthermore, multiple second through slots are provided inside the cover plate 19, so that the cover plate 19 does not seal the inside of the placement box 5. This prevents the water vapor generated by the bean seeds inside the placement box 5 after heating from being unable to escape, which would have an adverse effect on the efficiency of subsequent separation of the bean seed coat and cotyledons.

[0046] After the beans inside the four placement boxes 5 are heated by the microwave heating device for a period of time, the left-end feed port sealing plate 2 can be controlled to slide upward and open, and the conveyor belt 4 can be controlled to reverse, thus driving the four placement boxes 5 back to below the two fixed frames 6. This makes the two pressing plates 7 correspond to the positions of the multiple connecting plates 21. At this time, the telescopic ends of the two first electric telescopic rods 15 can be controlled to extend downward, causing one of the pressing plates 7 to press down on the tops of the multiple connecting plates 21. Under pressure, the multiple connecting plates 21 drive the multiple moving rods 23 and the flipping frame 24 to move downward together, applying downward force to one end of the rotating plate 26, causing one end of the rotating plate 26 to rotate downward, so that the top of the rotating plate 26... The bean seeds slide to the lower end. After the telescopic ends of the two first electric telescopic rods 15 retract downwards to return to their original positions, they can be elastically reset by the elastic plate 27 at the bottom of the rotating plate 26, causing the rotating plate 26 to rotate upwards and reset inside the placement box 5. The above steps are repeated, so that the other two first electric telescopic rods 15 drive another pressing plate 7 to press and reset the other multiple connecting plates 21, so that the rotating plate 26 can rotate up and down inside the placement box 5, so that the bean seeds on the top of the rotating plate 26 can be automatically turned over. Then, the conveyor belt 4 is controlled to drive the four placement boxes 5 back into the microwave heating device 1 for heating treatment, which can ensure that the bean seeds inside the four placement boxes 5 can be heated evenly.

[0047] Furthermore, to improve the turning effect of the bean seeds on the top of the rotating plate 26, after the above steps, the telescopic ends of multiple first electric telescopic rods 15 can be extended downwards, driving the two pressing plates 7 to press down on the multiple connecting plates 21 below. At the same time, the multiple connecting blocks 16 at the bottom of the two pressing plates 7 are respectively inserted and engaged with the corresponding connecting grooves 22. As the two sliders 17 move towards each other and away from each other inside the corresponding sliding grooves 14, the two pressing plates 7 and the multiple connecting plates 21 move towards each other and away from each other. This allows the two turning frames 24 to turn the bean seeds back and forth on the top of the corresponding rotating plate 26, further improving the turning effect of the bean seeds. This ensures that the subsequent microwave heating equipment 1 can uniformly heat the bean seeds inside the four placement boxes 5, ensuring the automatic separation of the bean seed skin and cotyledons.

[0048] Furthermore, while the beans are being turned over, the outer skin of some of the beans will automatically separate from the cotyledons. Smaller outer skins will pass through the first groove 25 inside the rotating plate 26 and accumulate on the inner bottom surface of the placement box 5, thereby achieving the effect of pre-separating the outer skin of some beans and improving the separation efficiency of the outer skin and cotyledons of beans.

[0049] After the microwave heating device 1 heats the beans inside the four placement boxes 5, the sealing plate 2 on the right end is opened upwards. As the conveyor belt 4 continues to rotate, the four placement boxes 5 rotate sequentially to the right end of the conveyor belt 4. During the rotation of the placement boxes 5 from above to below the conveyor belt 4, the cover plate 19 on the top of the placement box 5 will automatically rotate downwards by 90 degrees. The rotation of the cover plate 19 is limited by the limiting plate 20, so that the end of the cover plate 19 away from the placement box 5 abuts against the top opening of the separation box 9. Figure 7 As shown, since two baffles are installed on the side of the cover plate 19 near the placement box 5, after the cover plate 19 is rotated downwards by 90 degrees, the heated bean seeds inside the rotating plate 26 will slide downwards to the surface of the cover plate 19. With the help of the two baffles, the bean seeds will be guided into the interior of the separation box 9 along the cover plate 19. While the bean seeds are moving on the surface of the cover plate 19, some of the skin layer on the surface of the bean seeds will automatically rub off and fall down from multiple second channels, so that the skin layer is automatically removed, avoiding further processing.

[0050] As the bean seeds from the four placement boxes 5 enter the separation box 9 in sequence, the drive motor 13 drives the two rubber rollers 30 to rotate, thereby automatically rubbing the bean seeds inside the separation box 9 to separate the skin and cotyledons. The separated skin and cotyledons fall downwards to the top of the filter plate 31. With the help of the blower head 12, the lighter skin is blown into the collection box 10 and enters the collection bag 11 for collection and storage. The heavier cotyledons are discharged downwards through the gap at the lower end of the filter plate 31 into the preset collection container below for collection.

Clearly, many modifications and variations can be made based on the content of this specification.
