Description

Technical Field

[0001] The invention relates to the technical field of bean seed processing, and in particular to a device for separating the cortex and cotyledon of bean seeds. Background Art

[0002] Bean seeds refer to the seeds of leguminous plants, including soybeans, broad beans, peas, mung beans, kidney beans, adzuki beans, etc. Soybeans are divided into yellow beans, black beans, green beans, etc. according to their colors. Kidney beans can be divided into lentils, kidney beans, sword beans, French beans, cowpeas, etc. The colors of adzuki beans are red, yellow, light green, gray, white, tea, etc. During the production and processing of soybeans, soybeans contain about 8% of the skin, and the skin contains a large amount of cellulose, pigments, colloids and waxes. Separating the cortex and cotyledons of soybeans can increase the protein content of soybean meal and increase the processing capacity of the extractor, thereby improving the utilization rate and output rate of soybean protein. Soybean skins can be developed and utilized separately; selling soybean skins can offset the power consumption during peeling, increase the processing capacity of subsequent equipment by 6%-7%, reduce energy consumption during bean product processing and reduce equipment wear.

[0003] In the prior art, when peeling bean seeds, commonly used peeling methods include hot peeling, warm peeling, frozen peeling, etc. When ordinary soybeans are peeled by warm peeling, there is a problem of incomplete peeling; while the low temperature method is used for black bean peeling, which can protect the anthocyanin in the bean skin, but it is not suitable for soybean peeling due to the high production cost; and the hot peeling method is used for soybean peeling, the cost is lower than warm peeling, and the bean skin removal rate can be improved, but the bean kernel is highly broken, and the soybean protein loss is large when producing bean products.

[0017] 1. In the present invention, by means of the microwave heating device and the separation box, the cortex and cotyledons of bean grains can be automatically separated by the microwave peeling method, the bean grains are heated in a short time, the efficiency is extremely high, and the bean grains can be quickly peeled; and by means of the turning mechanism, during the heating process of the bean grains, the bean grains can be turned over conveniently with the help of the gaps of intermittent heating of the bean grains by the microwave heating device, so that the microwave heating device can heat the bean grains more evenly, further improving the efficiency of bean seed heating and subsequent separation of the cortex and cotyledons.

[0019] 3. In the invention, after the microwave heating device heats the bean seeds in the placement box, as the conveyor belt continues to rotate, the placement box is driven to rotate from the top to the bottom of the conveyor belt, so that the end of the cover away from the placement box is in contact with the top opening of the separation box, and the heated bean seeds inside the rotating plate will slide down to the surface of the cover and enter the interior of the separation box. While the bean seeds fall on the surface of the cover and move, part of the cortex on the surface of the bean seeds will automatically fall off due to friction and fall down from the multiple second through grooves, so that this part of the fallen cortex is automatically removed to avoid subsequent processing.

DETAILED DESCRIPTION

[0033] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Reference Figure 1-Figure 11, a bean seed cortex and cotyledon separation device, comprising a microwave heating device 1 and a mounting frame 3, the microwave heating device 1 is mounted on the top of the mounting frame 3, and blocking plates 2 are slidably mounted on both ends of the microwave heating device 1, a conveyor belt 4 is mounted inside the mounting frame 3 through multiple supporting shafts, a plurality of placement boxes 5 for placing bean seeds are mounted on the surface of the conveyor belt 4, and a turning mechanism for driving the bean seeds to turn is arranged inside the plurality of placement boxes 5, two fixed frames 6 are mounted on the top of the mounting frame 3, and a driving mechanism for driving the turning mechanism is arranged at the bottom of the two fixed frames 6, and a separation box 9 for separating the bean seed cortex and cotyledon is arranged at one end of the mounting frame 3, and an automatic separation mechanism is installed inside the separation box 9. By arranging blocking plates 2 at the feed inlet and the discharge port at both ends of the microwave heating device 1, after the conveyor belt 4 drives the plurality of placement boxes 5 to enter the interior of the microwave heating device 1, the feed inlet and the discharge port are blocked by controlling the two blocking plates 2 to slide downward, so as to prevent the microwave inside the microwave heating device 1 from leaking outward.

[0035] As a technical optimization solution of the present invention, the flipping mechanism includes a rotating plate 26 rotatably mounted inside the placement box 5, and elastic plates 27 are installed at the four corners of the bottom of the rotating plate 26. A plurality of first through slots 25 are provided inside the rotating plate 26. The elastic plate 27 is made of elastic plastic or other non-metallic materials, and can provide support and fixation for the rotating plate 26 in a horizontal state inside the placement box 5, and after pressing down one end of the rotating plate 26, the two corresponding elastic plates 27 below are deformed, so that one end of the rotating plate 26 can rotate downward, driving the bean seeds on the top of the rotating plate 26 to move synchronously.

[0036] As a technical optimization solution of the present invention, rectangular grooves are provided at both ends of the rotating plate 26, and telescopic plates 28 are installed inside the two rectangular grooves. The two telescopic plates 28 are connected to the inner wall of one side of the rectangular groove through multiple elastic members 29. Since one end of the rotating plate 26 will have a gap with the inner wall of the placement box 5 after rotating downward, with the help of the telescopic plates 28 arranged at both ends of the rotating plate 26, when the rotating plate 26 is in a horizontal state, the multiple elastic members 29 drive the telescopic plates 28 to be in a contracted state. When the rotating plate 26 rotates, the telescopic plates 28 can extend outward for a distance to fill the gap caused by the rotation, so as to prevent the bean grains on the top of the rotating plate 26 from falling down from the gap.

[0037] As a technical optimization solution of the present invention, a cover plate 19 is rotatably installed on the top of the placement box 5, a limit 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, and a discharge port is provided on the outer wall of one side of the placement box 5 close to the limit plate 20, and a sealing plate 18 is rotatably installed inside the discharge port. Since a plurality of first through grooves 25 are provided inside the rotating plate 26, after the bean seeds are heated by the microwave heating device 1, there will be a gap between the cortex on the surface and the cotyledons, so that part of the cortex automatically falls off, passes downward through the first through grooves 25 and falls on 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 at this time automatically rotates downward and opens, and pours out the small amount of cortex collected inside.

[0038] As a technical optimization solution of the present invention, a plurality of second through slots are provided inside the cover plate 19, wherein a moving rod 23 is slidably installed inside three of the second through slots, and a turning rack 24 is installed at the bottom ends of the plurality of moving rods 23 through the second through slots. By moving the moving rod 23 back and forth inside the three second through slots, the turning rack 24 can be driven to synchronously turn over the bean seeds on the top of the rotating plate 26, so that the microwave heating device 1 can fully heat them.

[0039] As a technical optimization solution of the present invention, a connecting plate 21 is installed on the top of the plurality of moving rods 23, and a connecting groove 22 is provided 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 plurality of moving rods 23 and the flip frame 24 can be driven to move synchronously.

[0040] As a technical optimization solution of the present invention, the driving mechanism includes a slide 14 opened at the bottom of the two fixed frames 6, two sliders 17 are installed inside the two slides 14, the bottom ends of the two sliders 17 are installed with a first electric telescopic rod 15, and the two matching first electric telescopic rods 15 are jointly installed with a pressing plate 7 at the telescopic ends, and a plurality of connecting blocks 16 are installed at the bottom of the pressing plate 7. Double-headed screws are preset inside the two slides 14, and the two sliders 17 are respectively matched with the outer walls of the corresponding double-headed screws, and a driving device is installed at one end of the two double-headed screws. While the driving device drives the double-headed screws to rotate, it can drive the two sliders 17 to move back and forth inside the corresponding slide 14; and then drive the first electric telescopic rod 15 and the pressing plate 7 below to move and adjust.

[0041] As a technical optimization solution of the present invention, two second electric telescopic rods 8 are installed on the outer walls of both sides 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 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 grains after heating in the placement box 5 can fall smoothly into the separation box 9.

[0042] As a technical optimization scheme of the present invention, the automatic separation mechanism includes two rubber rollers 30 rotatably installed inside the separation box 9, a driving motor 13 is installed on one side of the outer wall of the separation box 9, the output end of the driving 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 one side of the separation box 9 close to the driving motor 13, the outer wall of the output end of the driving motor 13 is rotatably matched with the rotating part of the first gear 33 through a belt 32, and a second gear 34 is installed on one end of the rotating part of the other rubber roller 30, and the first gear 33 is meshed with the second gear 34. The driving motor 13 can directly drive one of the rubber rollers 30 to rotate, and with the mutual cooperation between 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, so that the two matched rubber rollers 30 can squeeze and rub the heated bean grains, and promote the automatic separation of the cortex and cotyledons of the bean grains.

[0043] As a technical optimization scheme of the present invention, the separation box 9 is located below the two rubber rollers 30 and is installed with a filter plate 31 in an inclined state. A collection box 10 is installed at the end of the separation box 9 close to the high end of the filter plate 31. A collection bag 11 is installed at the bottom end of the collection box 10. A blow head 12 is installed at the end of the separation box 9 close to the low end of the filter plate 31. A gap is left between the low end of the filter plate 31 and the separation box 9. In actual use, the blow head 12 is connected to the external preset fan output end, so that the blow head 12 can blow wind to the surface of the filter plate 31, and separate the cortex and cotyledons that have fallen on the top of the filter plate 31 and have been rubbed, so that the lighter cortex is blown to the inside of the collection box 10 and enters the collection bag 11 for collection and storage, and the heavier cotyledons are discharged downward along the gap at the low end of the filter plate 31 to the inside of the preset collection container below for collection.

[0044] In the present invention, when the user uses the device, Figure 1As shown, two groups of placement boxes 5 are provided on the surface of the conveyor belt 4, each group consists of four, and are respectively located on the upper and lower sides of the conveyor belt 4. After one group of placement boxes 5 rotates to the bottom of the two fixing frames 6, the cover plate 19 is opened upwards, and an appropriate amount of bean grains are placed in the four placement boxes 5 in sequence, so that the bean grains entering the placement boxes 5 are located on the top of the rotating plate 26 in a horizontal state, and then the cover plate 19 is rotated downward to reset. As the conveyor belt 4 continues to rotate, the four placement boxes 5 are driven to enter the interior of the microwave heating equipment 1, and the two blocking plates 2 are controlled to slide downward to block the feed port and the discharge port at both ends of the microwave heating equipment 1, so that the microwaves generated inside the microwave heating equipment 1 can cause the cortex on the surface of the bean grains to expand due to heat, so that a tiny gap is generated between the cortex and the cotyledons.

[0045] Since a cover plate 19 is provided on the top of the placement box 5, it is possible to prevent some of the bean seeds from expanding due to the microwave heating and splashing outwards into the microwave heating device 1, and a plurality of second through grooves are provided inside the cover plate 19, so that the cover plate 19 is not sealed to the inside of the placement box 5, thereby preventing the water vapor generated by the bean seeds inside the placement box 5 after heating from being unable to dissipate outwards, which would have an adverse effect on the subsequent separation efficiency of the bean seed cortex and cotyledons.

[0046] After the bean seeds in the four placement boxes 5 are heated by the microwave heating device for a period of time, the feed port sealing plate 2 at the left end can be controlled to slide upward and open, and the conveyor belt 4 can be controlled to reverse, thereby driving the four placement boxes 5 to return to the bottom of the two fixed frames 6 again, so that the two pressing plates 7 correspond to the positions of the multiple connecting plates 21 respectively. At this time, the telescopic ends of two of the first electric telescopic rods 15 can be controlled to extend downward, driving one of the pressing plates 7 to press the tops of the multiple connecting plates 21 downward, so that the multiple connecting plates 21, after being subjected to pressure, drive the multiple moving rods 23 and the flipping frame 24 to move downward together, and apply force downward to press one end of the rotating plate 26, so that one end of the rotating plate 26 will rotate downward, so that the top of the rotating plate 26 The bean seeds slide to the lower end, and after the telescopic ends of the two first electric telescopic rods 15 are retracted downward and reset, they can be reset by means of the elasticity of the elastic plate 27 at the bottom of the rotating plate 26, driving the rotating plate 26 to rotate upward and reset inside the placement box 5, and repeat the above steps, 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, and then the conveyor belt 4 is controlled to drive the four placement boxes 5 to enter the interior of the microwave heating device 1 again for heating treatment, which can ensure that the bean seeds in the four placement boxes 5 can be heated evenly.

[0047] Moreover, in order to improve the turning effect of the bean grains on the top of the rotating plate 26, after performing the above steps, the telescopic ends of the multiple first electric telescopic rods 15 are controlled to extend downward, driving the two pressing plates 7 to press the multiple connecting plates 21 below downward, while driving the multiple connecting blocks 16 at the bottom of the two pressing plates 7 to be respectively inserted and matched with the corresponding connecting grooves 22. While controlling the two sliding blocks 17 to move in the directions of approaching and moving away from each other inside the corresponding sliding grooves 14, the two pressing plates 7 and the multiple connecting plates 21 are driven to move in the directions of approaching and moving away from each other, so that the two turning frames 24 can be driven to turn the bean grains back and forth on the top of the corresponding rotating plate 26, further improving the turning effect of the bean grains, ensuring that the subsequent microwave heating equipment 1 can evenly heat the bean grains in the four placement boxes 5, and ensuring the subsequent automatic separation effect of the cortex and cotyledons of the bean grains.

[0048] Moreover, while the bean seeds are being turned over, part of the cortex on the surface of the bean seeds will automatically separate from the cotyledons, and the cortex with a smaller volume will pass through the first through groove 25 inside the rotating plate 26 and fall on the inner bottom surface of the placement box 5 for accumulation, thereby achieving the effect of pre-separating part of the cortex of the bean seeds, thereby improving the separation efficiency of the cortex of the bean seeds and the cotyledons.

[0049] After the microwave heating device 1 heats the bean seeds in the four placement boxes 5, the sealing plate 2 at the right end is controlled to open upwards. As the conveyor belt 4 continues to rotate, the four placement boxes 5 are driven to rotate to the right end of the conveyor belt 4 in sequence. During the rotation of the placement boxes 5 from the top to the bottom of the conveyor belt 4, the cover plate 19 on the top of the placement boxes 5 will be automatically rotated downward by 90 degrees. The rotation of the cover plate 19 is limited by the limiting plate 20, so that at this time, the end of the cover plate 19 away from the placement box 5 is abutted against the top opening of the separation box 9. Figure 7 As shown, since two baffles are installed on the side of the cover 19 close to the placement box 5, after the cover 19 is rotated downward by 90 degrees, the bean grains that have been heated inside the rotating plate 26 will slide downward to the surface of the cover 19, and with the help of the two baffles, the bean grains will follow the guidance of the cover 19 into the interior of the separation box 9. While the bean grains fall on the surface of the cover 19 and move, part of the surface cortex of the bean grains will automatically fall off due to friction and fall downward from multiple second through grooves, so that this part of the fallen cortex is automatically removed to avoid subsequent processing.

[0050] As the bean seeds in the four placement boxes 5 enter the separation box 9 in turn, the two rubber rollers 30 are driven to rotate by the driving motor 13, so that the bean seeds entering the separation box 9 can be automatically rubbed to automatically separate the cortex and cotyledons of the bean seeds. The separated cortex and cotyledons fall downward on the top of the filter plate 31. With the help of the blowing head 12, the lighter cortex is blown into the collection box 10 and enters the collection bag 11 for collection and storage. The heavier cotyledons are discharged downward through the gap at the lower end of the filter plate 31 to the preset collection container below for collection.

[0051] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
