Description

Technical Field

[0001] The invention relates to the technical field of soybean pretreatment, and in particular to a soaking pretreatment device and a pretreatment method before soybean refining. Background Art

[0002] There are several important reasons for soaking soybeans before grinding, mainly related to the structure, taste, nutrition and optimization of subsequent processing of soybeans. The specific reasons are as follows: soybeans themselves contain high cellulose and hard structure, and direct grinding will make it difficult for soybean particles to be completely broken. Through soaking, soybeans absorb water, become soft, and the cell walls swell and crack, which makes it easier to break during grinding, thereby increasing the yield and reducing residue. Soaking can make soybeans fully absorb water and swell, so that nutrients (such as protein and fat) can be better released during grinding, thereby improving the quality and yield of soy milk. Soybeans contain enzyme substances such as lipoxygenase that are easy to produce fishy smell. Soaking can dissolve these substances in the soaking water, reduce the bean smell, and thus improve the flavor of soy milk. Soybeans contain some anti-nutritional ingredients, such as phytic acid, trypsin inhibitors, etc. These ingredients will affect the body's absorption of protein and minerals. Through soaking, some anti-nutritional substances can be dissolved in water or partially decomposed, which helps to improve the nutrient absorption efficiency of soy milk. After soaking, the size and hardness of soybean particles tend to be consistent, which can make the particles more uniform during grinding, and the texture of the final soy milk is more delicate and smooth. If you grind soybeans directly without soaking, it may cause uneven grinding, affecting the taste and quality.

[0003] The soybean soaking pretreatment device is a device specially used for large-scale processing of soybeans. It aims to improve the soaking efficiency and processing effect. It is suitable for mass production occasions such as soybean milk factories and soybean product processing plants. A typical soybean soaking pretreatment device can include the following parts: Bean feeding system: used to transport dry beans into the soaking device. Soaking tank: soak soybeans to make them absorb water and swell. Water circulation system: provide fresh water and discharge waste water to ensure that soybeans are always in a clean water environment during the soaking process. Temperature control system: can adjust the water temperature to keep it at around 20-25°C suitable for soaking, which helps to shorten the soaking time and is especially suitable for processing needs in different seasons.

[0004] The existing soaking pretreatment devices and pretreatment methods before soybean refining are relatively complex, and mostly use large-scale single devices for processing. On the one hand, the work efficiency is low. On the other hand, if the device fails or processes a large amount of soybeans at a time, it is easy to delay the work progress, resulting in subsequent work not being carried out on time.

[0005] In view of the above situation, in order to overcome the above technical problems, the present invention designs a soaking pretreatment device and pretreatment method before soybean refining, which solves the above technical problems. Summary of the invention

[0006] The technical purpose to be achieved by the present invention is to design a soaking pretreatment device and pretreatment method before soybean refining, change the existing pretreatment method of individual large-scale devices, adopt multiple devices to work continuously, ensure the qualified rate of processed soybeans, improve work efficiency, reduce the impact of failures and save energy loss.

[0007] In order to achieve the above technical objectives, the present invention provides the following technical solutions: A soaking pretreatment device before soybean refining has a reasonable structural design, can improve the pretreatment efficiency of soybeans, and ensure the uniformity and cleanliness of the soaking process. The device consists of multiple important components, mainly including a soaking mechanism, a flushing mechanism, a cleaning component, a stirring component and an aeration component. The coordinated work of each component greatly improves the overall performance of the device.

[0008] The soaking mechanism is the core part of the device, which is responsible for soaking and pre-treating soybeans. There are multiple soaking mechanisms, which are installed together continuously to achieve continuous soybean processing. Through reasonable design, soybeans can fully absorb water and swell, ensuring that soybeans are easier to process in the subsequent pulping process, improving the pulping rate and the quality of soybean milk. The soaking mechanism can automatically control the water temperature and soaking time, so that the soybeans can be processed under the most suitable conditions, further improving efficiency.

[0009] A flushing mechanism is installed above the device to separate soybeans from impurities generated during the processing. During the soaking process of soybeans, some impurities, scum and sediment may be released. The flushing mechanism separates these impurities from the soybeans by timed water injection or circulating water flow to ensure the cleanliness of the soybean soaking process. The flushing mechanism not only improves the cleanliness of the soybeans, but also effectively reduces secondary pollution after soaking, providing higher quality raw materials for the subsequent refining step.

[0010] In order to further ensure the removal of impurities, the device is also equipped with a cleaning component. The cleaning component is installed in the flushing mechanism and removes the washed impurities through automatic movement. The impurities can be discharged smoothly from the soaking area to avoid the backflow or deposition of impurities affecting the soaking effect of soybeans. The role of this component is to reduce the need for manual cleaning and improve the automation level and production efficiency of the equipment.

[0011] Inside the soaking mechanism, the stirring assembly is rotated by a pneumatic device. The function of the stirring assembly is to ensure that the soybeans will not accumulate during the soaking process, so that each soybean can fully contact the water and achieve complete soaking. Stirring also helps impurities float up and be discharged in time through the flushing mechanism. The design of the stirring assembly takes into account the fragility of soybeans, ensuring that the soybeans will not be damaged during the stirring process, while effectively improving the uniformity of soaking.

[0012] The aeration component is installed in the middle of the stirring component, which helps stir the soaked soybeans by releasing compressed gas. During the aeration process, the bubbles can generate a rising force, pushing the impurities attached to the surface of the soybeans to the water surface and taking them away through the flushing mechanism. This design not only further improves the soaking effect, but also enhances the cleaning effect, making it easier to remove impurities on the surface of the soybeans, ensuring the cleanliness of the soybeans and the smooth progress of subsequent processing.

[0013] The soaking mechanism is mainly composed of a soaking cylinder, a bottom plate, an air inlet pipe, a power chamber, a collecting channel and a transition chamber. The soaking cylinder is installed on the ground and provides the main space for soaking soybeans. The bottom plate is located inside the soaking cylinder, which plays a supporting and separating role to ensure that the soybeans can be evenly distributed. The air inlet pipe is installed on the outer surface of the soaking cylinder, through which air or other gases are supplied to assist in stirring and cleaning the soybeans during the soaking process. The power chamber is arranged inside the soaking cylinder to provide stirring and mixing effects. The collecting channel is located between the power chamber and the transition chamber, and is responsible for connecting and transmitting gas. The transition chamber is opened in the center of the power chamber to ensure that the various parts can work together smoothly to achieve efficient soaking and pretreatment.

[0014] The power chamber is arranged in a circular array around the transition chamber to form a uniform layout design. The outer end of the power chamber is connected to the air inlet pipe to ensure that the gas can smoothly enter the power chamber. The inner end of the power chamber is connected to the transition chamber through a collecting channel, so that the gas can flow between the transition chamber and the power chamber, thereby achieving uniform airflow distribution and effective stirring and mixing functions, and improving the effect of soybean soaking pretreatment.

[0015] The flushing mechanism consists of a sealing cover plate, a mounting protrusion, a mounting groove, a baffle, a limiting groove and a through hole, and is designed to improve the cleaning efficiency during the soybean soaking process. The sealing cover plate is installed on the top of the soaking mechanism to ensure the sealing of the soaking environment and prevent external contaminants from entering. Mounting protrusions and mounting grooves are set on both sides of the cover plate, so that the cover plate can be firmly fixed on the equipment and convenient for disassembly and assembly. Baffles are installed on the other two sides of the cover plate to further prevent water from splashing or impurities from entering. The inner side of the baffle is provided with a limiting groove, which can play a positioning and limiting role during cleaning or operation, ensuring precise control of the flushing process. A number of through holes are also designed on the cover plate, through which water can be injected or impurity water can be discharged, effectively completing the functions of flushing and impurity separation. This structural design allows the soybeans to be fully rinsed during the soaking process to ensure the cleaning effect.

[0016] The cross-sectional shape of the limit groove is designed to be trapezoidal, which helps to improve the stability and sealing of the structure, so that the cover plate can be more closely connected to the soaking mechanism during the flushing process, thereby effectively preventing water leakage or cover plate displacement. The trapezoidal design of the limit groove also enhances the precise positioning function during operation, ensuring that the device can operate efficiently for a long time.

[0017] In addition, the holes are located directly above the soaking mechanism, and the aperture is cleverly designed. The aperture value is smaller than the minimum diameter of qualified soybeans, ensuring that soybeans will not overflow through these holes during the rinsing process. Only tiny impurities and wastewater can be discharged through these holes, thus ensuring the integrity and cleanliness of the soybeans. This design can effectively prevent the loss of soybeans, while improving the efficiency of impurity discharge, making the soaking and rinsing process more efficient and reliable. Through the precise control of the aperture, soybeans and impurities can be separated, further improving the processing quality of the product.

[0018] The cleaning assembly consists of a cleaning push plate, a drainage groove, a fixed plate and a limit block, which is designed to improve the removal efficiency of impurities during the flushing process. The cleaning push plate is installed in the middle of the flushing mechanism. As the core cleaning component, it is responsible for pushing impurities out of the soybean soaking area. The design of the push plate can ensure that impurities are smoothly removed from the soaking area, effectively prevent impurities from remaining, and ensure the cleanliness of the soybeans.

[0019] A drainage groove is provided on the side of the cleaning push plate. When the cleaning push plate is reset, water can flow upward with the help of the drainage groove to reduce the reset resistance and improve the cleaning effect and efficiency.

[0020] The fixed plate is also installed on the side of the cleaning push plate. Its function is to provide support and stability for the cleaning push plate, ensuring that the push plate will not shift or loosen during operation. At the same time, the limit block is installed on the side of the fixed plate to play a positioning role, so that the cleaning push plate always remains in the predetermined track during operation, ensuring that impurities can be accurately pushed away to avoid interfering with the normal processing flow of soybeans.

[0021] The stirring assembly consists of a rotating shaft, a power fan blade and a stirring fan blade, and is designed to improve the uniformity and efficiency of stirring the soybeans during the soaking process. The rotating shaft is installed inside the soaking mechanism and serves as the core support structure of the stirring system, responsible for driving the entire stirring process. Through the operation of the rotating shaft, the stirring assembly can achieve continuous rotational motion, ensuring that the soybeans remain in a dynamic state during the soaking process to avoid soybean accumulation or precipitation.

[0022] The power fan blades are installed on the lower surface of the rotating shaft and are mainly responsible for providing power support for the stirring process. The design of the power fan blades can effectively convert the pressure of the compressed air provided by the power chamber into rotational energy to drive the flow of soybeans and soaking liquid. As the power fan blades rotate, the soybeans are constantly stirred in the soaking liquid, ensuring that each soybean can fully contact the water and achieve a uniform soaking effect.

[0023] The stirring blades located above the power blades further enhance the stirring effect. The stirring blades are used to stir the soaking liquid and soybeans more evenly, avoiding incomplete or over-soaking of soybeans in some areas. The two-layer blade design makes the stirring process more efficient and stable, which helps to improve the overall quality of soaking.

[0024] The inflation assembly is composed of a control assembly, an inflation rod and an inflation hole, and is intended to improve the gas circulation and cleaning effect during the soybean soaking process. The control assembly is installed inside the soaking mechanism and is responsible for managing the inflation process, ensuring the release and flow adjustment of gas to meet different soaking requirements. The control assembly is designed to enable unidirectional flow of gas.

[0025] The inflation rod is installed on the side of the control component as a gas transmission channel, which can effectively transport gas to the soybean soaking area. Its structural design takes into account the smoothness of gas flow to ensure that the inflation process will not be hindered.

[0026] The aeration holes located above the aeration rod are responsible for releasing gas into the soaking liquid. The location and diameter of the aeration holes are precisely designed to release gas evenly, helping the soybeans to fully absorb water during the soaking process and promoting the rise of impurities, thereby improving the overall cleaning effect.

[0027] The control assembly consists of a control sleeve, a mounting bracket, a return spring and a control ball, and is primarily responsible for managing the operation and regulation of the inflation assembly. The control sleeve is mounted inside the immersion mechanism, providing a solid support and protection for the entire control system. Its design ensures that the internal components can operate smoothly and avoid external interference.

[0028] Inside the control sleeve, the mounting bracket supports and fixes the return spring and control ball, providing a stable platform. The structural design of the mounting bracket takes into account space utilization and functionality to ensure smooth integration of other components.

[0029] The reset spring is installed under the mounting bracket and plays an important role in elastic support. The reset spring can respond quickly to help the control component reset and ensure the sensitivity and reliability of the system. The control ball is installed under the reset spring and acts as a regulating valve for the gas flow. It can control the gas to enter the immersion cylinder only through the transition chamber, ensuring the stability and accuracy of the inflation process.

[0030] A soaking pretreatment method for soybeans before refining, the method is used in conjunction with the above-mentioned soaking pretreatment device for soybeans before refining; the steps of the method are as follows: S1: Select clean, pest-free and mildew-free soybeans and pour them into multiple soaking cylinders. Add sufficient water (20-25°C) into the soaking cylinders, close the sealing covers one by one, and start the device. S2: Compressed gas enters the power chamber through the air inlet pipe to drive the stirring assembly to rotate, so that the soybeans are kept rolling in the soaking cylinder to achieve full soaking; S3: The gas passes through the control assembly and the inflation rod, and a large number of bubbles emerge in the water to clean the soybeans. The soaking process lasts for 1-2 hours; S4: The cleaning component slides back and forth every 5 minutes or so to push away the rising impurities to ensure the soaking of the soybeans.

[0031] The beneficial effects of the present invention are as follows: 1. The present invention brings many significant benefits by changing the existing individual large-scale device pretreatment method and adopting multiple devices to operate continuously. The continuous operation of multiple devices ensures that soybeans are always in the best state during the treatment process. This method can better control the soaking, rinsing and cleaning process of each batch, reduce unqualified soybeans caused by improper treatment, and improve the overall qualification rate. The parallel operation of multiple devices can greatly shorten the processing time and improve production efficiency. Compared with the traditional single device processing method, the continuous operation mode can achieve higher processing capacity, meet the needs of large-scale production, and help to cope with the pressure of market changes and increased orders. The use of multiple devices makes the production process more flexible. If one of the devices fails, the other devices can still operate normally, avoiding the stagnation of the entire production line. This redundant design can effectively reduce the risks in the production process and improve the stability of the system. The reasonable configuration and scheduling of multiple devices can optimize the efficiency of energy use and avoid the energy waste caused by excessive processing or repeated operations in traditional methods. By accurately controlling the operation of each device, the overall energy consumption can be reduced, which helps enterprises achieve a more sustainable production model.

[0032] 2. The present invention can achieve more uniform processing in the soaking, washing and other links through a continuous operation mode, thereby improving the quality of soy milk and soy products. This consistency not only enhances consumer satisfaction, but also establishes a good brand image for the company. The combination of multiple devices makes the production line more flexible and can quickly adjust the production plan according to different market demands. This flexibility enables the company to better cope with seasonal fluctuations and market changes, and enhances its market competitiveness. By optimizing the soybean pretreatment method, the present invention significantly improves production efficiency and product quality, reduces production risks and energy consumption, and brings sustainable development advantages to the company.

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] like Figure 1-9As shown, a soaking pretreatment device before soybean refining has a reasonable structural design, can improve the pretreatment efficiency of soybeans, and ensure the uniformity and cleanliness of the soaking process. The device is composed of multiple important components, mainly including a soaking mechanism 1, a flushing mechanism 2, a cleaning component 3, a stirring component 4 and an aeration component 5. The coordinated work of each component greatly improves the overall performance of the device.

[0038] The soaking mechanism 1 is the core part of the device, which is responsible for soaking and pre-treating the soybeans. There are multiple soaking mechanisms 1, which are installed together continuously to achieve continuous soybean processing. Through reasonable design, the soybeans can fully absorb water and swell, ensuring that the soybeans are easier to process in the subsequent refining process, improving the pulping rate and the quality of the soy milk. The soaking mechanism 1 can automatically control the water temperature and soaking time, so that the soybeans are processed under the most suitable conditions, further improving efficiency.

[0039] A flushing mechanism 2 is installed above the device to separate soybeans from impurities generated during the processing. During the soaking process of soybeans, some impurities, scum and sediment may be released. The flushing mechanism 2 separates these impurities from the soybeans by means of timed water injection or circulating water flow to ensure the cleanliness of the soybean soaking process. The flushing mechanism 2 not only improves the cleanliness of the soybeans, but also effectively reduces secondary pollution after soaking, providing higher quality raw materials for the subsequent refining step.

[0040] In order to further ensure the removal of impurities, the device is also provided with a cleaning component 3. The cleaning component 3 is installed in the flushing mechanism 2, and removes the washed impurities by automatic movement. The impurities can be smoothly discharged from the soaking area to prevent the impurities from flowing back or depositing and affecting the soaking effect of soybeans. The function of this component is to reduce the need for manual cleaning and improve the automation level and production efficiency of the equipment.

[0041] Inside the soaking mechanism 1, the stirring component 4 is rotated by a pneumatic device. The function of the stirring component 4 is to ensure that the soybeans will not accumulate during the soaking process, so that each soybean can fully contact the water and achieve complete soaking. Stirring also helps the impurities to float up and be discharged in time through the flushing mechanism 2. The design of the stirring component 4 takes into account the fragility of soybeans, ensuring that the soybeans will not be damaged during the stirring process, while effectively improving the uniformity of soaking.

[0042] The aeration component 5 is installed in the middle of the stirring component 4, and helps to stir the soaked soybeans by releasing compressed gas. During the aeration process, the bubbles can generate a rising force, pushing the impurities attached to the surface of the soybeans to the water surface and taking them away through the flushing mechanism 2. This design not only further improves the soaking effect, but also enhances the cleaning effect, making it easier to remove impurities on the surface of the soybeans, ensuring the cleanliness of the soybeans and the smooth progress of subsequent processing.

[0043] like Figure 3-4 As shown, the soaking mechanism 1 is mainly composed of a soaking cylinder 11, a bottom plate 12, an air inlet pipe 13, a power chamber 14, a collecting channel 15 and a transition chamber 16. The soaking cylinder 11 is installed on the ground and provides the main space for soaking soybeans. The bottom plate 12 is located inside the soaking cylinder 11, and plays a supporting and separating role to ensure that the soybeans can be evenly distributed. The air inlet pipe 13 is installed on the outer surface of the soaking cylinder 11, through which air or other gases are supplied to assist in stirring and cleaning the soybeans during the soaking process. The power chamber 14 is arranged inside the soaking cylinder 11 to provide stirring and mixing effects. The collecting channel 15 is located between the power chamber 14 and the transition chamber 16, and is responsible for connecting and transmitting gas. The transition chamber 16 is opened in the center of the power chamber 14 to ensure that the various parts can work together smoothly to achieve efficient soaking and pretreatment.

[0044] The power chamber 14 is arranged in a circular array around the transition chamber 16 to form a uniform layout design. The outer end of the power chamber 14 is connected to the air inlet pipe 13 to ensure that the gas can smoothly enter the power chamber 14. The inner end of the power chamber 14 is connected to the transition chamber 16 through the collecting channel 15, so that the gas can flow between the transition chamber 16 and the power chamber 14, thereby achieving uniform airflow distribution and effective stirring and mixing functions, and improving the effect of soybean soaking pretreatment.

[0045] like Figure 5 As shown, the flushing mechanism 2 is composed of a sealing cover plate 21, a mounting protrusion 22, a mounting groove 23, a baffle 24, a limiting groove 25 and a through hole 26, and is designed to improve the cleaning efficiency during the soybean soaking process. The sealing cover plate 21 is installed on the top of the soaking mechanism 1 to ensure the sealing of the soaking environment and prevent external pollutants from entering. Mounting protrusions 22 and mounting grooves 23 are provided on both sides of the cover plate, so that the cover plate can be firmly fixed on the equipment and convenient for disassembly and assembly. Baffles 24 are installed on the other two sides of the cover plate to further prevent water from splashing or impurities from entering. The inner side of the baffle 24 is provided with a limiting groove 25, which can play a positioning and limiting role during cleaning or operation to ensure accurate control of the flushing process. A number of through holes 26 are also designed on the cover plate, through which water can be injected or impurity water can be discharged, effectively completing the functions of flushing and impurity separation. This structural design allows the soybeans to be fully rinsed during the soaking process to ensure the cleaning effect.

[0046] The cross-sectional shape of the limiting groove 25 is designed to be trapezoidal, which helps to improve the stability and sealing of the structure, so that the cover plate can be more closely connected to the soaking mechanism 1 during the flushing process, thereby effectively preventing water leakage or cover plate displacement. The trapezoidal design of the limiting groove 25 also enhances the precise positioning function during operation, ensuring that the device can operate efficiently for a long time.

[0047] In addition, the holes 26 are opened in the area just above the soaking mechanism 1, and the aperture design is ingenious, and the aperture value is smaller than the minimum diameter of qualified soybeans, ensuring that soybeans will not overflow through these holes during the flushing process. Only tiny impurities and wastewater can be discharged through these holes, thereby ensuring the integrity and cleanliness of the soybeans. This design can effectively avoid the loss of soybeans, while improving the efficiency of impurity discharge, making the soaking and flushing process more efficient and reliable. Through the precise control of the diameter of the hole 26, soybeans and impurities can be separated, further improving the processing quality of the product.

[0048] like Figure 6 As shown, the cleaning assembly 3 is composed of a cleaning push plate 31, a drainage groove 32, a fixing plate 33 and a stopper 34, which is intended to improve the efficiency of removing impurities during the flushing process. The cleaning push plate 31 is installed in the middle position of the flushing mechanism 2. As the core cleaning component, it is responsible for pushing impurities out of the soybean soaking area. The design of the push plate can ensure that impurities are smoothly removed from the soaking area, effectively prevent impurities from remaining, and ensure the cleanliness of the soybeans.

[0049] A drainage groove 32 is provided on the side of the cleaning push plate 31. The function of the drainage groove 32 is that when the cleaning push plate 31 is reset, water can flow upward with the help of the drainage groove 32 to reduce the reset resistance and improve the cleaning effect and efficiency.

[0050] The fixed plate 33 is also installed on the side of the cleaning push plate 31, and its function is to provide support and stability for the cleaning push plate 31, ensuring that the push plate will not shift or loosen during operation. At the same time, the limit block 34 is installed on the side of the fixed plate 33, which plays a positioning role, so that the cleaning push plate 31 always remains in the predetermined track during operation, ensuring that impurities can be accurately pushed away, and avoiding interference with the normal processing flow of soybeans.

[0051] like Figure 7 As shown, the stirring assembly 4 is composed of a rotating shaft 41, a power blade 42 and a stirring blade 43, and is designed to improve the uniformity and efficiency of stirring the soybeans during the soaking process. The rotating shaft 41 is installed inside the soaking mechanism 1, and serves as the core support structure of the stirring system, which is responsible for driving the entire stirring process. Through the operation of the rotating shaft 41, the stirring assembly 4 can achieve continuous rotational motion, ensuring that the soybeans remain in a dynamic state during the soaking process to avoid soybean accumulation or precipitation.

[0052] The power blades 42 are installed on the lower surface of the rotating shaft 41 and are mainly responsible for providing power support for the stirring process. The design of the power blades 42 can effectively convert the pressure of the compressed air provided by the power chamber 14 into rotational energy to drive the flow of soybeans and soaking liquid. As the power blades 42 rotate, the soybeans are constantly stirred in the soaking liquid, ensuring that each soybean can fully contact the water and achieve a uniform soaking effect.

[0053] The stirring blades 43 located above the power blades 42 further enhance the stirring effect. The stirring blades 43 are used to stir the soaking liquid and soybeans more evenly to avoid incomplete or over-soaking of soybeans in some areas. The design of two layers of blades makes the stirring process more efficient and stable, which helps to improve the overall quality of soaking.

[0054] like Figure 8 As shown, the inflation component 5 is composed of a control component 51, an inflation rod 52 and an inflation hole 53, which is intended to improve the gas circulation and cleaning effect during the soybean soaking process. The control component 51 is installed inside the soaking mechanism 1, responsible for managing the inflation process, ensuring the release and flow adjustment of gas to meet different soaking requirements. The design of the control component 51 enables the unidirectional flow of gas.

[0055] The inflation rod 52 is installed on the side of the control assembly 51, and as a gas transmission channel, it can effectively transport the gas to the soybean soaking area. Its structural design takes into account the smoothness of gas flow to ensure that the inflation process will not be hindered.

[0056] The inflation hole 53 located above the inflation rod 52 is responsible for releasing gas into the soaking liquid. The opening position and aperture of the inflation hole 53 are precisely designed to facilitate uniform release of gas, help the soybeans fully absorb water during the soaking process and promote the rise of impurities, thereby improving the overall cleaning effect.

[0057] like Fig. 9 As shown, the control assembly 51 is composed of a control sleeve 511, a mounting frame 512, a return spring 513 and a control ball 514, and is mainly responsible for managing the operation and adjustment of the inflation assembly 5. The control sleeve 511 is installed inside the immersion mechanism 1 to provide stable support and protection for the entire control system. Its design ensures that the internal components can operate smoothly and avoid external interference.

[0058] Inside the control sleeve 511, the mounting frame 512 plays a supporting and fixing role, providing a stable platform for the return spring 513 and the control ball 514. The structural design of the mounting frame 512 takes space utilization and functionality into consideration to ensure that other components can be smoothly integrated.

[0059] The reset spring 513 is installed below the mounting frame 512 and plays an important role in elastic support. The reset spring 513 can respond quickly to help the control assembly 51 reset, ensuring the sensitivity and reliability of the system. The control ball 514 is installed below the reset spring 513 and acts as a regulating valve for the gas flow. It can control the gas to enter the soaking cylinder 11 only through the transition chamber 16, ensuring the stability and accuracy of the inflation process.

[0060] A soaking pretreatment method for soybeans before refining, the method is used in conjunction with the above-mentioned soaking pretreatment device for soybeans before refining; the steps of the method are as follows: S1: Select clean soybeans without insect pests or mildew and pour them into multiple soaking cylinders 11, add sufficient water (20-25°C) into the soaking cylinders 11, close the sealing cover plates 21 in turn, and start the device; S2: The compressed gas enters the power chamber 14 through the air inlet pipe 13 to drive the stirring assembly 4 to rotate, so that the soybeans are kept rolling in the soaking cylinder 11 to achieve full soaking; S3: The gas passes through the control component 51 and the inflation rod 52, and a large number of bubbles emerge in the water to clean the soybeans. The soaking process lasts for 1-2 hours; S4: The cleaning component 3 performs reciprocating sliding every 5 minutes or so to push away the rising impurities to ensure the soaking of the soybeans.

[0061] During the working process of the present invention, the staff selects clean, pest-free and mildew-free soybeans and pours them into a plurality of soaking cylinders 11, adds sufficient clean water (20-25°C) into the soaking cylinders 11, closes the sealing cover plates 21 in sequence, and starts the device; The compressed gas is pumped into the power chamber 14 through the air inlet pipe 13, thereby driving the power blades 42 to rotate, so that the stirring blades 43 on the upper part of the stirring component 4 rotate, and the soybeans are kept rolling in the soaking cylinder 11 to achieve full soaking; the gas enters the transition chamber 16 through the collecting channel 15, passes through the control component 51 into the inflation rod 52, and rushes out of the inflation port to generate a large number of bubbles, so as to clean the soybeans. The soaking process lasts for 1-2 hours; The cleaning push plate 31 in the cleaning component 3 slides under the drive of the external cylinder, and reciprocates every 5 minutes or so to push away the impurities that rise onto the sealing cover plate 21. During this process, a water source is used to perform a unidirectional water flow flushing on the sealing cover plate 21, which helps to clean impurities on the one hand, and replenishes water in the soaking cylinder 11 on the other hand, thereby ensuring the soaking treatment of the soybeans.
