Description

A soybean ripening device Technical Field

[0001] This utility model relates to the field of soybean processing technology, and in particular to a soybean ripening device. Background Technology

[0002] With global population growth and rising living standards, the demand for soybeans and their products continues to climb. However, the soybean industry currently faces numerous technological bottlenecks. In the planting stage, soybean yields are limited by issues such as variety adaptability, pest and disease infestation, and declining soil fertility, resulting in low yields in some regions. In the processing sector, traditional processing techniques suffer from low resource utilization and significant nutrient loss; for example, soybean oil extraction suffers from low oil yield and high residual oil in the meal, while soybean protein processing faces challenges such as insufficient functionality and severe product homogenization. Therefore, research on soybean variety improvement, efficient planting, and deep processing technologies has become an urgent need for the industry's development and is of great significance for promoting the sustainable development of the soybean industry.

[0003] Soybean ripening is a crucial step in soybean processing, typically involving raw material screening, washing, crushing, and ripening. Raw material screening directly impacts the quality and market competitiveness of subsequent products. In traditional soybean ripening processes, raw material screening relies heavily on manual labor or simple screening equipment, making it difficult to accurately remove impurities such as dirt, stones, and shriveled grains. This compromises the purity of the raw materials, affecting subsequent processing efficiency and potentially leading to inconsistent product quality. Summary of the Invention

[0004] The main purpose of this utility model is to provide a soybean ripening device. By setting a vibration structure and a screen in the screening barrel, the screen generates stable and continuous vibration. By taking advantage of the differences in shape, size and density between soybeans and stones, impurities such as soil, stones and shriveled grains are effectively separated, and high-quality soybean raw materials with full grains and no mold are accurately screened out.

[0005] To achieve the above objectives, this utility model proposes a soybean ripening device, comprising:

[0006] A screening barrel is provided with a screen inside the screening barrel. A vibration structure is provided below the screen. The vibration structure drives the screen to vibrate, causing the material on the screen to jump continuously.

[0007] A washing tank, located on one side of the screening tank, is used to rinse the surface of soybeans and remove surface dust and impurities.

[0008] A crushing barrel, located on one side of the washing barrel, is used to crush the washed soybeans;

[0009] A maturation tank, located on one side of the crushing tank, is used to heat-treat soybeans.

[0010] Optionally, the vibration structure includes a driving component, an impacting component, and a first elastic component. The driving component is installed outside the screening barrel, the impacting component is installed inside the screening barrel, the output end of the driving component extends into the screening barrel and abuts against the impacting component, and one end of the first elastic component is fixedly connected inside the screening barrel, and the other end is connected to the impacting component.

[0011] Optionally, the screening barrel is provided with a first positioning post, and the striking element is installed on the first positioning post and can rotate on the first positioning post.

[0012] Optionally, the screening barrel is provided with a second positioning post, which is located below the first positioning post.

[0013] Optionally, the striking member is provided with a column, one end of the first elastic member is fixedly connected to the second positioning column, and the other end is connected to the column.

[0014] Optionally, limiting grooves are respectively formed on the opposite side walls of the screening barrel, and the two ends of the screen are respectively located in the limiting grooves.

[0015] Optionally, the limiting groove is provided with a limiting post, and both ends of the screen pass through the limiting post and are connected to it, and can move along the limiting post.

[0016] Optionally, a second elastic element is sleeved on the limiting post, with one end of the second elastic element abutting the top of the limiting groove and the other end abutting the screen.

[0017] Optionally, the screening barrel is equipped with a rotating component, and the output end of the rotating component is equipped with a stirring roller, which is located above the screen.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention utilizes a screen and vibration structure within a screening chamber. The ingenious combination of the screen and vibration structure, along with the synergistic effect of impact and elastic components, generates stable and continuous vibration in the screen. By exploiting the differences in shape, size, and density between soybeans and pebbles, it effectively separates impurities such as soil, pebbles, and shriveled grains, precisely selecting plump, mold-free, high-quality soybean raw materials. This lays a solid foundation for subsequent processing and significantly improves product quality. The design of the screen ends with limiting grooves, limiting posts, and a second elastic component further increases the screen amplitude, significantly enhancing screening efficiency. Simultaneously, the rotating components within the screening chamber drive the stirring rollers, preventing soybean accumulation and accelerating the screening process between soybeans and pebbles, saving screening time and costs.

[0030] This utility model proposes a soybean ripening device 100.

[0031] Please refer to Figures 1-3. In one embodiment of this utility model, the soybean ripening device 100 includes a screening tank 10, a washing tank 60, a crushing tank 70, and a ripening tank 80. The screening tank 10 is equipped with a screen 20, and a vibration structure 30 is provided below the screen 20. The vibration structure 30 drives the screen 20 to vibrate, causing the material on the screen 20 to jump continuously. The washing tank 60 is located on one side of the screening tank 10 and is used to wash the surface of the soybeans to remove surface dust and impurities. The crushing tank 70 is located on one side of the washing tank 60 and crushes the washed soybeans. The ripening tank 80 is located on one side of the crushing tank 70 and heat-treats the soybeans.

[0032] In this embodiment, the screening barrel 10, through the cooperation of the screen 20 and the vibration structure 30, screens plump, impurity-free, and mold-free soybean raw materials by vibration, removing impurities such as mud, stones, and shriveled grains from the soybeans to ensure the purity of the raw materials, which is beneficial for subsequent processing and product quality. After the raw materials are screened, the screened soybeans enter the washing barrel 60 for washing. The washing barrel 60 is equipped with a spray pipe 61, which is connected to an external water source, to spray and rinse the soybeans in the washing barrel 60 to remove surface dust and impurities. The moisture content of the washed soybeans should be controlled within an appropriate range, generally 12%-14%. The washed soybeans enter the crushing barrel 70 for crushing into 2-4 pieces. The purpose of crushing is to increase the contact area between the soybeans and the heat source, improve the ripening efficiency, and facilitate the subsequent peeling operation.

[0033] The crushed soybeans are then placed in a softening pot for softening treatment. Under specific temperature and humidity conditions, the moisture content of the soybeans is evenly distributed, and the texture softens. The softening temperature is generally controlled at 70-80℃ for 20-30 minutes. The softened soybeans are then placed in a ripening tank 80 for steaming and roasting, which denatures the proteins in the soybeans, destroys anti-nutritional factors, and improves the quality and oil yield of the oil. The steaming and roasting process is divided into two stages: moistening the soybeans and roasting them. In the moistening and steaming stage, the temperature is controlled at 100-110℃, so that the moisture content of the soybean slices reaches 15%-20%, and the time is 30-40 minutes. In the roasting stage, the temperature is gradually increased to 120-130℃, and the moisture content is reduced to 2%-3%, and the time is 20-30 minutes.

[0034] After ripening, soybeans need to be cooled promptly to prevent overheating and subsequent quality degradation. Air cooling or water cooling can be used to lower the soybean temperature to room temperature or slightly above room temperature, generally 30-40℃. Once cooled and inspected, the soybeans are ready for packaging. Different packaging methods, such as woven bags, plastic bags, or ton bags, can be used depending on the intended use and sales requirements. Packaged soybeans should be stored in a dry, well-ventilated warehouse to prevent moisture and mold growth.

[0035] It should be noted that the crushing barrel 70 can be a crusher, the maturation barrel 80 can be a steaming and frying pan, and the washing barrel 60 can be an ordinary storage basin. All of the above are existing technologies and will not be described in detail here.

[0036] In one embodiment of the present invention, the vibration structure 30 includes a driving member 31, an impact member 32, and a first elastic member 33. The driving member 31 is installed outside the screening barrel 10, the impact member 32 is installed inside the screening barrel 10, the output end of the driving member 31 extends into the screening barrel 10 and abuts against the impact member 32, one end of the first elastic member 33 is fixedly connected inside the screening barrel 10, and the other end is connected to the impact member 32.

[0037] The screening barrel 10 is provided with a first positioning post 11. The striking member 32 is installed on the first positioning post 11 and can rotate on the first positioning post 11. The screening barrel 10 is provided with a second positioning post 12, which is located below the first positioning post 11. The striking member 32 is provided with a column 34. One end of the first elastic member 33 is fixedly connected to the second positioning post 12, and the other end is connected to the column 34.

[0038] In this embodiment, the striking element 32 is L-shaped, the driving element 31 can be an electric push rod, and the first elastic element 33 can be a tension spring, but is not limited to these. The output end of the driving element 31 is provided with a push block 35. The longer end of the striking element 32 abuts against the screen 20, and the shorter end abuts against the push block 35. The column 34 is disposed on the shorter end of the striking element 32.

[0039] Under normal circumstances, when the push block 35 is not abutting against the shorter end of the striking member 32, the longer end of the striking member 32 remains against the screen 20 under the tension of the first elastic member 33. When the driving member 31 is activated to drive the push block 35 to extend and abut against the shorter end of the striking member 32, the striking member 32 rotates around the first positioning post 11, causing the longer end of the striking member 32 to disengage from the screen 20. 5. When the striking member 32 retracts and disengages, under the tension of the first elastic member 33, the striking member 32 rotates by pulling the column 34, causing the longer end of the striking member 32 to rebound and press against the screen 20 again. This process is repeated. With the cooperation of the driving member 31 and the first elastic member 33, the striking member 32 repeatedly strikes the screen 20, generating vibration, which causes the material on the screen 20 to jump continuously, removing impurities such as mud, stones, and shriveled grains from the soybeans.

[0040] In one embodiment of this utility model, limiting grooves 13 are respectively opened on the opposite side walls of the screening barrel 10, and the two ends of the screen 20 are respectively located in the limiting grooves 13; a limiting post 14 is provided in the limiting groove 13, and the two ends of the screen 20 pass through the limiting post 14 and are connected to it, and can move along the limiting post 14; a second elastic member 50 is sleeved on the limiting post 14, one end of the second elastic member 50 abuts against the top of the limiting groove 13, and the other end abuts against the screen 20.

[0041] In this embodiment, the height of the limiting groove 13 is greater than the width of the screen 20, allowing the screen 20 to move longitudinally within the limiting groove 13. The second elastic element 50 can be a spring, but is not limited to this. It is understood that, with the cooperation of the driving member 31 and the first elastic element 33, the striking member 32 strikes the screen 20 upwards, causing the screen 20 to move upwards. When the striking member 32 disengages from the screen 20, under the elastic force of the first elastic element 33, the screen 20 returns to its initial position, increasing the amplitude and improving the screening efficiency.

[0042] It should be noted that soybeans are typically near-spherical or elliptical particles with relatively uniform size. Stones, on the other hand, are irregularly shaped and may differ in size from soybeans. The screen 20 has sieve holes of a specific size. When the screen 20 vibrates, soybean particles can pass through the sieve holes that match their size, while stones, due to their irregular shape or larger size, have difficulty passing through, thus achieving initial separation. Stones are generally denser than soybeans. During the vibration of the screen 20, the denser stones experience greater gravitational force, resulting in a different motion than soybeans. Stones tend to move downwards in the material layer, closer to the screen surface, while soybeans are more easily thrown up by the vibration or remain on the upper layer of the material. This difference in motion due to density helps to separate stones and soybeans on the screen surface, making it easier for stones to remain on the screen while soybeans fall through the sieve holes.

[0043] In one embodiment of the present invention, a rotating component 40 is provided inside the screening barrel 10, and a stirring roller 41 is provided at the output end of the rotating component 40. The stirring roller 41 is located above the screen 20.

[0044] In this invention, the rotating component 40 can be a common geared motor, which can directly drive the stirring roller 41 to rotate. The screening barrel 10 has a feed inlet 15 at the top and a discharge outlet 16 at the bottom. It can be understood that soybeans enter the screening barrel 10 through the feed inlet 15. The rotating component 40 drives the stirring roller 41 to rotate, which can prevent the soybeans from accumulating and disperse them. In conjunction with the vibration structure 30, it accelerates the screening of soybeans and stones. The soybeans fall from the screen 20 and are discharged from the discharge outlet, while the stones remain on the screen 20.

[0045] Working principle: Soybeans are placed into the screening barrel 10 through the feed inlet 15. The rotating component 40 is activated to drive the stirring roller 41 to rotate, preventing soybean accumulation. Simultaneously, the driving component 31 is activated to push the pusher block 35 into contact with the striking component 32. With the cooperation of the driving component 31 and the first elastic component 33, the striking component 32 repeatedly strikes the screen 20, generating vibration. This causes the material on the screen 20 to continuously bounce, removing impurities such as mud, stones, and shriveled soybeans. The screened soybeans then proceed to subsequent processes such as washing, crushing, and maturation.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
