Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a soybean seed coat and embryo separation device and a soybean processing production line. Background Technology

[0002] In the soybean processing industry, to obtain high-value-added soybean meal products, soybeans typically require pretreatment, including crushing, dehulling (i.e., separating the seed coat from the germ), and puffing. Among these processes, efficient separation of the seed coat and germ is crucial, as the seed coat is primarily composed of cellulose, while the germ is rich in protein and oil. Incomplete separation results in residual seed coat in the germ reducing the final protein content of the soybean meal, while germ embedded in the seed coat leads to a waste of oil and protein, directly impacting the yield and quality of the high-protein meal.

[0003] However, existing soybean processing lines can only transport, crush, and sort soybeans, and cannot effectively separate the seed coat and embryo. In the crushed soybean particles, some seed coats and embryos adhere tightly due to moisture, oil, or mechanical rolling effects, forming "adherent composite particles." These adherent composite particles are directly fed into subsequent sorting equipment. This prevents the sorting equipment from effectively separating the seed coat and embryo, ultimately affecting the yield and quality of high-protein soybean meal. Utility Model Content In view of this, the present invention provides a soybean seed coat and embryo separation device and a soybean processing production line to solve the problem that the existing soybean seed coat and embryo cannot be effectively separated, resulting in poor yield and quality of high-protein soybean meal.

[0004] In a first aspect, this utility model provides a device for separating soybean seed coat and embryo kernel, comprising: The shell has a receiving cavity; A drive motor is mounted on the housing. A drive shaft is connected to the drive motor and is rotatably disposed in the receiving cavity. The drive shaft is provided with multiple separation plates at intervals along the circumference. Each separation plate is provided with multiple grooves at intervals along the axial direction of the drive shaft to form multiple blades. The side of each blade is a working end face and the working end face is a plane.

[0005] Beneficial effects: This utility model's soybean seed coat and embryo separation device feeds crushed soybeans into the housing cavity, where they come into contact with the separation plate. A drive motor rotates the transmission shaft, and the blades of the separation plate on the transmission shaft beat the crushed soybeans. The beaten soybeans can even pass through grooves and be beaten again by the blades of the next separation plate. Furthermore, the working end face of the blades is flat, forming surface contact with the crushed soybeans, which effectively separates the seed coat and embryo adhering to the surface of the crushed soybeans, preventing embryo breakage and thus improving the yield and quality of high-protein soybean meal.

[0006] In one alternative embodiment, the blades on adjacent separation plates are offset along the axial direction of the drive shaft.

[0007] Beneficial effects: The staggered leaf distribution ensures that broken beans are continued to be beaten by the leaves of the next separating plate after passing through the groove, forming an efficient and uniform reciprocating continuous beating, which further breaks the adhesion between the seed coat and the kernel, thus improving the separation efficiency.

[0008] In one alternative embodiment, multiple separation plates are symmetrically distributed about the axis of the drive shaft.

[0009] Beneficial effects: Distributing multiple separation plates symmetrically around the axis of the drive shaft helps to ensure dynamic balance and further improve separation efficiency.

[0010] In one optional embodiment, the drive shaft is provided with end plates at its opposite ends, and the two end plates are respectively connected to the opposite ends of each of the separation plates. An accommodating space is formed between adjacent separation plates. At least one partition is provided between the two end plates. The partition is sleeved on the outside of the drive shaft and is used to divide the accommodating space into multiple subspaces.

[0011] Beneficial effects: Setting a partition on the drive shaft can improve the structural strength of the drive shaft and divide the accommodating space into multiple sub-spaces. Each sub-space can be used to individually beat the broken material, effectively preventing the broken beans from moving laterally. It is also suitable for separating different quantities of broken beans, making it widely applicable.

[0012] In one alternative embodiment, the partition is integrally formed with the drive shaft.

[0013] Beneficial effects: The partition and drive shaft are integrally molded, which facilitates processing and use.

[0014] In one alternative embodiment, the partition is detachably disposed on the separation plate.

[0015] Beneficial effects: The partition can be detachably installed on the separation plate, allowing for selection of whether to install the partition according to actual needs, and also facilitating the disassembly and maintenance of the partition.

[0016] In one alternative embodiment, each of the partitions includes a plurality of sub-plates arranged sequentially along the circumference of the drive shaft, each of the sub-plates being inserted into the groove.

[0017] Beneficial effects: Using grooves to install sub-boards facilitates quick installation and removal of sub-boards without taking up extra space. The installation position is flexible, and the size of each sub-space can be adjusted. There is no need to set up additional installation structures, which helps to simplify the structure and reduce the cost of use.

[0018] In one optional embodiment, the drive motor is a variable frequency motor, used to adjust the speed of the transmission shaft by frequency conversion.

[0019] Beneficial effects: For high-moisture, tightly bound broken beans, increasing the drive motor to raise the rotation speed of the drive shaft increases the frequency and force of beating, achieving effective separation. For dry, brittle broken beans, reducing the drive motor to lower the rotation speed of the drive shaft provides a gentle beating force, achieving separation while preventing the kernel from being crushed, thus further expanding the applicability.

[0020] Secondly, this utility model also provides a soybean processing production line, comprising: A crusher is used to crush soybeans into crushed particles that are a mixture of seed coat and embryo. The crusher is provided with a strip-shaped discharge port at the bottom. The soybean seed coat and kernel separation device described above has a shell with an upward-facing opening, which is correspondingly positioned to the discharge port.

[0021] Beneficial Effects: This soybean processing production line first crushes soybeans into crushed particles containing a mixture of seed coat and embryo using a crusher. The crushed soybeans are then fed from the crusher's outlet into an open cavity above the housing, where they come into contact with the separating plates. A drive motor rotates the transmission shaft, and the blades of the separating plates on the shaft beat the crushed soybeans. The beaten soybeans can even pass through grooves and be further beaten by the blades of the next separating plate. Furthermore, the working surfaces of the blades are flat, forming surface contact with the crushed soybeans, which effectively separates the seed coat and embryo adhering to the surface of the crushed soybeans, preventing embryo breakage and thus improving the yield and quality of high-protein soybean meal.

[0022] In one alternative embodiment, the bottom of the housing is provided with an outlet; The soybean processing production line further includes: a discharge channel, which is located below the shell and connected to the outlet. Multiple buffer rollers are spaced apart in the discharge channel to buffer the falling speed of the soybeans. At least one air separation device is also connected to the side wall of the discharge channel to separate the seed coat and the kernel.

[0023] Beneficial effects: After separation, the seed coat and embryo enter the discharge channel from the outlet at the bottom of the shell. Under their own gravity, they fall and are slowed down by the buffer roller, extending the residence time. The air separation device can effectively separate the seed coat and embryo, thereby further improving the yield and quality of high-protein soybean meal. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0029] According to an embodiment of the present invention, a soybean seed coat and embryo separation device is provided, mainly comprising: a housing 1, a drive motor 2, and a transmission shaft 3. The housing 1 has a receiving cavity 101 and an opening 102 facing upwards. The drive motor 2 is mounted on the housing 1. The transmission shaft 3 is connected to the drive motor 2 and is rotatably disposed within the receiving cavity 101. The transmission shaft 3 has multiple separation plates 4 spaced circumferentially, and each separation plate 4 has multiple grooves 401 spaced axially along the transmission shaft 3 to form multiple blades 402. The side surface of the blades 402 is a working end face, and the working end face is flat.

[0030] Therefore, the soybean seed coat and embryo separation device provided in this embodiment of the invention feeds crushed soybeans into the receiving cavity 101 through the opening 102 on the top of the shell 1, where they come into contact with the separation plate 4. The drive motor 2 drives the transmission shaft 3 to rotate, and the blades 402 of the separation plate 4 on the transmission shaft 3 beat the crushed soybeans. The beaten soybeans can also pass through the groove 401 and be beaten again by the blades 402 of the next separation plate 4. Furthermore, the working end face of the blade 402 is flat, forming surface contact with the crushed soybeans, which facilitates the effective separation of the seed coat and embryo adhering to the surface of the crushed soybeans and avoids embryo breakage, thereby improving the yield and quality of high-protein soybean meal.

[0031] Specifically, the axial direction of the drive shaft 3 is as follows: Figure 1 As shown by the arrow X in the image, the vertical direction is as follows: Figure 1 As indicated by arrow Z in the diagram. The circumferential direction of drive shaft 3 is as follows. Figure 3 As indicated by arrow R in the diagram. Figure 5 As shown, the opening 102 at the top of the shell 1 is used to receive crushed beans, and the bottom of the shell 1 is also provided with an outlet for discharging the seed coat and embryo after being beaten and separated. The drive motor 2 can be directly connected to one end of the drive shaft 3 through the coupling 11 to improve transmission efficiency. The drive shaft 3 is rotatably mounted in the receiving cavity 101 through a bearing seat. The separating plate 4 extends along the axial direction of the drive shaft 3. The depth of the groove 401 can be selected according to actual needs. After the groove 401 is opened on the separating plate 4, the plate surface below the blade 402 can also play the role of beating the crushed beans.

[0032] It should be noted that this embodiment of the invention does not limit the number of separating plates 4, nor the number of blades 402 on the separating plates 4; these can be selected as needed. For example, the number of separating plates 4 can be two, three, or more. For example, as shown... Figure 3 As shown, there are 12 separation plates 4 along the circumference of the drive shaft 3.

[0033] Furthermore, this embodiment of the invention does not limit the connection method between the separation plate 4 and the drive shaft 3; any existing connection method can be selected as needed. For example, the separation plate 4 and the drive shaft 3 can be welded together as a single unit.

[0034] In one embodiment, such as Figure 2 As shown, the blades 402 on adjacent separation plates 4 are staggered along the axial direction of the drive shaft 3. The staggered distribution of the blades 402 ensures that the broken beans are continued to be beaten by the blades 402 of the next separation plate 4 after passing through the groove 401, reducing the beating blind zone and forming an efficient and uniform reciprocating continuous beating, which further breaks the adhesion between the seed coat and the kernel, thus improving the separation efficiency.

[0035] In one embodiment, such as Figure 3 As shown, multiple separation plates 4 are symmetrically distributed around the axis of the drive shaft 3, which helps to ensure dynamic balance under high-speed rotation and further improves separation efficiency. That is, multiple separation plates 4 are distributed at equal intervals along the circumference of the drive shaft 3.

[0036] In one embodiment, such as Figure 1 As shown, end plates 5 are provided at opposite ends of the drive shaft 3, and the two end plates 5 are respectively connected to opposite ends of each separation plate 4. For example, the end plates 5 are fixedly connected to the ends of the separation plates 4 by fasteners, such as bolts. Figure 2 and Figure 4 As shown, adjacent separation plates 4 form an accommodating space, and at least one partition 6 is provided between the two end plates 5. The partition 6 is sleeved outside the drive shaft 3 and is used to divide the accommodating space into multiple sub-spaces. The separation plates 4 are provided with spaces to avoid the partition 6.

[0037] A partition 6 is installed on the drive shaft 3. On the one hand, it serves as a reinforcing rib to improve the structural strength of the drive shaft 3. On the other hand, it divides the accommodating space into multiple sub-spaces, each of which can be used to individually tap the broken material, effectively preventing the broken beans from moving laterally. It is also suitable for separating different quantities of broken beans, making it widely applicable. The end plate 5 and the separation plate 4 together form multiple accommodating spaces, and the partition 6 further divides each accommodating space into multiple sub-spaces.

[0038] It is understandable that when multiple partitions 6 are provided, the multiple partitions 6 are spaced apart on the drive shaft 3, and adjacent partitions 6 and separation plates 4 also form a subspace.

[0039] It should be noted that this embodiment of the utility model does not limit the connection method between the partition 6 and the transmission shaft 3, and any existing connection method can be selected as needed.

[0040] In one embodiment, the partition 6 is integrally formed with the drive shaft 3, which facilitates processing and use. For example, the partition 6 and the drive shaft 3 are welded together as a single unit.

[0041] In one embodiment, the partition 6 is detachably mounted on the separation plate 4. Whether or not to install the partition 6 can be selected according to actual needs, and it also facilitates the disassembly and maintenance of the partition 6.

[0042] Furthermore, in one embodiment, each partition 6 includes a plurality of sub-plates arranged sequentially along the circumference of the drive shaft 3. Each sub-plate is inserted into a groove 401 and detachably connected to the separation plate 4. Using the groove 401 to install the sub-plates facilitates quick installation and removal of the sub-plates without occupying additional space. The installation position is flexible, allowing adjustment of the size of each sub-space, and there is no need to set up additional installation structures, which helps to simplify the structure and reduce the cost of use.

[0043] For example, when the number of broken beans is small, the distance between adjacent partitions 6 or the distance between partition 6 and end plate 5 can be shortened to separate the seed coat and embryo in a smaller subspace.

[0044] Specifically, the sub-plate can be a multi-segment fan-shaped plate, with multiple sub-plates inserted into corresponding grooves 401 and forming a circular partition 6. To improve the installation stability of the sub-plate, the sub-plate is interference-fitted with the groove 401, and the sub-plate can also be provided with lugs for fixed connection to the drive shaft 3 by bolts. For example, threaded holes are provided on the lugs and the drive shaft 3 respectively, and bolts pass through the threaded holes to fix the sub-plate to the drive shaft 3.

[0045] In one embodiment, the drive motor 2 is a variable frequency motor, used to adjust the rotational speed of the transmission shaft 3. For high-moisture, tightly bound broken beans, the drive motor 2 increases the rotational speed of the transmission shaft 3, increasing the beating frequency and force to achieve effective separation. For dry, fragile broken beans, the drive motor 2 reduces the rotational speed of the transmission shaft 3, providing a gentle beating force, achieving separation while preventing the kernels from being crushed, thus further expanding the applicability.

[0046] In some other embodiments, multiple blades 402 can be directly mounted on the drive shaft 3, for example, by welding multiple blades 402 onto the drive shaft 3.

[0047] According to an embodiment of the present invention, on the other hand, as... Figure 5 As shown, a soybean processing production line is also provided, mainly including: a crusher 7 and a soybean seed coat and embryo separation device. The crusher 7 is used to crush soybeans into crushed particles that are a mixture of seed coat and embryo, and a strip-shaped discharge port is provided below the crusher 7. The opening 102 of the shell 1 of the soybean seed coat and embryo separation device is correspondingly arranged with the discharge port.

[0048] Therefore, the soybean processing production line provided in this embodiment first crushes soybeans into crushed particles containing a mixture of seed coat and embryo using a crusher 7. The crushed soybeans are then fed from the discharge port of the crusher 7 into the opening 102 above the housing 1 and into the receiving cavity 101 of the housing 1, allowing the crushed soybeans to contact the separating plate 4. The drive motor 2 drives the transmission shaft 3 to rotate, and the blades 402 of the separating plate 4 on the transmission shaft 3 beat the crushed soybeans. The beaten soybeans can also pass through the groove 401 and be further beaten by the blades 402 of the next separating plate 4. Furthermore, the working end face of the blade 402 is flat, forming surface contact with the crushed soybeans, which facilitates the effective separation of the seed coat and embryo adhering to the surface of the crushed soybeans and avoids embryo breakage, thereby improving the yield and quality of high-protein soybean meal.

[0049] Specifically, such as Figure 5 As shown, the soybean seed coat and embryo separation device is located below the crusher 7. Since the crusher 7 is generally long and narrow, its strip-shaped discharge port can be set to correspond to the opening 102 of the shell 1 to ensure that the crushed soybeans can fall smoothly into the receiving cavity 101.

[0050] In one embodiment, such as Figure 5 As shown, the bottom of the shell 1 is provided with an outlet. The soybean processing production line also includes: a discharge channel 8. The discharge channel 8 is located below the shell 1 and is connected to the outlet. Multiple buffer rollers 9 are spaced apart in the discharge channel 8. The multiple buffer rollers 9 are used to buffer the falling speed of soybeans. The side wall of the discharge channel 8 is also connected to at least one air separation device 10. The air separation device 10 is used to sort seed coats and kernels.

[0051] After separation, the seed coat and embryo enter the discharge channel 8 through the outlet at the bottom of the shell 1. They fall under their own gravity and are slowed down by the buffer roller 9, extending their residence time in the air-separation zone. The air-separation device 10 effectively separates the seed coat and embryo, further improving the yield and quality of high-protein soybean meal. Due to the difference in density and suspension velocity between the seed coat and embryo, the lighter seed coat is blown towards the collection channel under the action of airflow, while the heavier embryo continues to fall, thus achieving efficient and precise air-separation.

[0052] Furthermore, such as Figure 5 As shown, the air separation device 10 can be configured with multiple air ducts along the vertical direction.

[0053] Furthermore, a storage box can be installed at the bottom of the discharge channel 8 to store the sorted kernels that fall down. An observation window 12 can also be installed on the side plate of the discharge channel 8 to observe the interior of the discharge channel 8 in real time.

[0054] It should be noted that in the embodiments of this utility model, the specific structures of the crusher 7 and the air classifier 10 can be directly adopted from existing structures. Therefore, the embodiments of this utility model do not impose too many restrictions on them.

[0055] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
