Description

Technical Field

[0001] This utility model relates to the field of food machinery technology, specifically to a drum-type soybean product filter. Background Technology

[0002] In the food processing industry, especially in the production of soy products, the importance of pulp-residue separation is self-evident. Currently, the two most common pulp-residue separation methods on the market are vibrating screens and centrifugal separation technology.

[0003] Centrifugal separators use high-speed rotation to generate powerful centrifugal force, thereby separating pulp from residue. However, this equipment faces numerous challenges in practical applications. Its extremely high rotational speed makes commissioning incredibly complex and tedious, requiring specialized technicians with deep expertise and extensive practical experience to ensure its proper operation. Although centrifugal force can separate pulp from residue to some extent, the instability of rotational speed and the inherent properties of the materials themselves inevitably result in a significant amount of residue remaining in the soy milk. This residue severely negatively impacts the quality of soy products, making the final product coarse in texture, significantly reducing its smoothness and creaminess, thus greatly affecting its market competitiveness and lowering consumer acceptance.

[0004] Vibratory separators use vibration to separate the pulp from the residue. However, this method has inherent flaws; its separation effect is far from ideal and is extremely incomplete. During the separation process, a large amount of soy milk remains in the residue. This not only results in significant waste of raw materials, directly causing production targets to fall short, but also, from an economic perspective, the low raw material utilization rate means that companies need to invest more raw materials to produce the same quantity of qualified products, significantly increasing production costs. Simultaneously, limited production capacity prevents effective increases in sales revenue. Under the dual pressure of increased costs and stagnant revenue, the overall economic efficiency of the company is severely reduced, hindering its further development.

[0005] Furthermore, the patented technologies previously proposed by the applicant (application numbers 201120190510.1 and 202120128139X) have also revealed a series of problems that cannot be ignored in practical applications. For example, the technical solution lacks a key component, the filter roller, and the filter screen is designed to be too small, failing to effectively cover and process large flow rates of material. In actual filtration processes, due to the lack of an effective filter roller for preliminary screening and separation of materials, and the fact that the undersized filter screen cannot provide sufficient filtration area and precision, a large amount of soybean residue cannot be fully intercepted and separated, resulting in a consistently low soybean residue separation efficiency. This seriously affects overall production efficiency, and the quality of the produced products is also difficult to guarantee, falling far short of meeting the ever-growing market demand.

[0006] In conclusion, the various shortcomings of existing technologies in residue filtration have become key factors restricting the development of the soybean product manufacturing industry. Utility Model Content

[0007] The purpose of this utility model is to provide a drum-type soybean product filter machine. The device consists of a frame and a filter device. The filter device can be tilted at multiple angles via a lifting component, which facilitates loading and unloading and subsequent cleaning. The drum and the filter screen assembly are fitted inside the rotating drum and rotate synchronously. During rotation, soybean milk flows out from the filter screen assembly. At the same time, the scraper assembly scrapes off the soybean residue remaining in the filter screen assembly, preventing the soybean residue from clogging the filter screen assembly. This achieves high-efficiency separation of soybean milk and soybean residue, which not only improves the taste of soybean milk and the quality of soybean products, but also increases production and economic benefits.

[0008] This utility model is achieved through the following technical solution:

[0009] A drum-type soybean product filter machine, comprising:

[0010] The frame has lifting components on both sides of its bottom.

[0011] A slurry filtering device, comprising a tilting drum, a rotating drum, a filter screen assembly, and a scraper assembly;

[0012] The tilting cylinder is connected to the top of the frame via a bearing seat, and the output end of the lifting assembly is connected to the tilting cylinder, so that the tilting cylinder rotates around the bearing seat;

[0013] The filter assembly and the rotating drum are fitted inside the flipping cylinder and arranged sequentially from the inside to the outside. The rotating drum can drive the filter assembly to rotate in the same direction along its own axis through a drive assembly.

[0014] One end of the scraper assembly is mounted at the opening of the flipping cylinder, and the other end of the scraper assembly extends into the filter assembly and slides against the inner wall surface of the filter assembly.

[0015] In this solution, the frame and filtration device together form a complete and efficient pulp-residue separation system, achieving effective separation of soy milk and soy residue. The frame and bottom lifting assembly provide stable support for the entire filtration machine and enable the tilting drum to tilt at multiple angles, facilitating loading, unloading, and cleaning. The tilting drum is connected to the frame via a bearing seat and its rotation is controlled by the lifting assembly. The rotating drum and filter screen assembly are fitted inside the tilting drum and rotate synchronously under the drive assembly, causing the soy milk to flow out of the filter screen assembly under centrifugal force. At the same time, the scraper assembly is mounted at the opening of the tilting drum, and its part extending into the filter screen assembly slides against the inner wall surface to scrape off residual soy residue in time, preventing the filter screen from clogging. This ensures that the pulp-residue separation process is continuously and efficiently carried out, improving the taste of soy milk, the quality of soy products, and increasing production and economic benefits.

[0016] As a further technical solution for the slurry filter, the open end of the rotating drum is evenly distributed with multiple sets of rollers along its own axis, and the outer wall surface of the rotating drum is tangent to the outer wall surface of all the rollers.

[0017] In this design, the rollers provide stable support for the rotating drum, ensuring smooth operation and reducing swaying and deviation. This guarantees that the soy milk is evenly subjected to centrifugal force within the filter assembly, improving the separation efficiency and stability of the pulp and residue. Furthermore, the tangential design effectively reduces friction between the rotating and tipping drums, minimizing component wear, extending equipment lifespan, reducing energy consumption, improving overall operating efficiency, and ensuring the filter machine operates stably and efficiently for extended periods.

[0018] As a further technical solution for the slurry filter, the scraper assembly includes a scraper body and a scraper. The open end of the tilting cylinder is provided with a mounting post that matches and connects to the scraper body. One end of the scraper is connected to the scraper body, and the other end of the scraper extends into the filter assembly and abuts against the inner wall surface of the filter assembly.

[0019] In this design, a mounting post is installed at the opening end of the rotating drum to match and connect the scraper body, providing a stable mounting foundation for the scraper assembly and ensuring its positional stability during the operation of the filter press. The connection structure between the scraper body and the scraper allows the scraper to effectively extend into the filter assembly and contact the inner wall surface. During filter press operation, as the filter assembly and rotating drum rotate, the scraper promptly scrapes off the soybean residue adhering to the inner wall of the filter assembly, preventing residue buildup and clogging of the filter screen. This ensures the filter screen's filtration efficiency, maintaining a stable and efficient pulp-residue separation process. This contributes to the continuous production of pure soy milk, improves the quality of soy products, and avoids downtime for cleaning due to filter screen clogging. It also increases production efficiency, reduces equipment maintenance costs, and brings better economic benefits to soy product manufacturers.

[0020] As a further technical solution for the slurry filter, a soft brush is also provided on the side of the scraper that contacts the filter screen assembly.

[0021] In this solution, the soft brush allows for more thorough cleaning of residual soybean residue on the inner wall of the filter assembly. Compared to relying solely on scraping with a scraper, it can penetrate deep into the mesh openings of the filter, brushing away small, easily adhered soybean residue particles that are difficult to remove by the scraper. This further improves the cleaning effect of the filter, effectively preventing clogging, ensuring its permeability, and maintaining stable and efficient filtration performance. This not only helps improve the quality of pulp-residue separation, resulting in purer soy milk and thus enhancing the taste and quality of soy products, but also extends the lifespan of the filter, reducing the frequency of filter replacement due to frequent clogging, lowering production costs, increasing production efficiency, and ensuring that the filter machine maintains good working condition during long-term operation, bringing better economic benefits and production stability to soy product manufacturers.

[0022] As a further technical solution for the pulp filter, the filter assembly includes a filter screen, and an mounting ring is connected to the bottom end of the inner cavity of the rotating drum;

[0023] The filter screen is connected to a first support ring and a fourth support ring at both ends. The first support ring is connected to the rotating drum through a connecting assembly, and the fourth support ring is connected to the mounting ring.

[0024] In this design, the filter screen is connected to a first support ring and a fourth support ring at both ends. The first support ring is connected to the rotating drum via a connecting assembly, allowing the filter screen to rotate with the drum. During rotation, centrifugal force is used to separate the pulp and residue. The fourth support ring is connected to the mounting ring at the bottom of the rotating drum's inner cavity. This design provides a stable bottom support for the filter screen, ensuring that it will not deform or shift when rotating at high speed and subjected to the impact of soy milk, thus ensuring the stability and reliability of the filtration process. Simultaneously, this structure helps to evenly distribute the force on the filter screen, extending its service life and ensuring continuous and efficient pulp-residue separation. This, in turn, improves the quality and yield of soy milk, bringing better economic benefits to soy product production.

[0025] As a further technical solution for the slurry filter, the connecting assembly includes multiple sets of fixed columns, a third ear plate, and a nut. The multiple sets of fixed columns are evenly distributed and connected to the open end of the rotating drum. The third ear plate is connected to the fixed columns and locked by the nut thread. The outer edge of the first support ring is clamped to the third ear plate.

[0026] In this design, multiple sets of fixed posts evenly distributed at the open end of the rotating drum provide multiple connection points for the first support ring, making the connection more stable and the force evenly distributed. The third ear plate on the outer edge of the first support ring matches the fixed post, and a nut is then threadedly connected to the fixed post and tightened against the third ear plate, achieving a reliable connection between the rotating drum and the first support ring in the filter assembly. This connection method not only facilitates installation and disassembly, making equipment maintenance and filter replacement easier, but also ensures that the filter assembly and the rotating drum maintain a close synchronous rotation relationship during the operation of the slurry filter. This allows the filter to work stably under centrifugal force, effectively preventing problems such as filter shaking and displacement caused by loose connections, thereby ensuring the high efficiency and stability of slurry separation and improving the overall performance of the slurry filter.

[0027] As a further technical solution for the slurry filter, the filter screen is made of a flexible material, and the connecting assembly also includes a spring;

[0028] The spring and the nut are sequentially sleeved on the fixed post, and the third ear plate is connected between the spring and the nut. When the spring is not subjected to external force, the filter screen is in a taut state.

[0029] In this design, the flexible filter screen better adapts to filtration needs under different working conditions. It deforms under the impact of soy milk and centrifugal force, preventing damage from rigid collisions and extending its lifespan. The spring design cleverly solves the installation and tension maintenance issues of the flexible filter screen during use. When no external force is applied, the filter screen remains taut, ensuring it stays flat and evenly stressed during filter press operation. This effectively prevents localized dents, blockages, or uneven filtration caused by slack, guaranteeing stable and efficient pulp-slag separation. Furthermore, the connection between the spring and nut on the fixed column allows for easy adjustment of the filter screen tension according to actual needs, adapting to different material characteristics and production process requirements. This further enhances the versatility and reliability of the filter press, contributing to improved product quality and production efficiency while reducing production costs.

[0030] As a further technical solution for the slurry filter, the filter assembly further includes a second support ring and a third support ring, the second support ring and the third support ring being spaced apart and connected to the outer edge of the filter screen, and located between the first support ring and the fourth support ring.

[0031] In this design, the second and third support rings provide additional intermediate support points for the filter screen, effectively enhancing its structural strength and stability as it rotates with the drum. Especially when the filter screen is subjected to the impact of soy milk and centrifugal force, the second and third support rings prevent excessive deformation, wrinkling, or damage, ensuring the filter screen maintains its optimal filtration shape. This multi-support-point design further optimizes the stress distribution on the filter screen, making it more reliable during long-term operation, reducing downtime for maintenance due to filter screen damage, improving the overall efficiency of the pulp filter, and ensuring the continuity and stability of the pulp-residue separation process.

[0032] As a further technical solution for the slurry filter, the slurry filter device also includes a connecting plate, and the bearing seats are arranged in pairs and connected to the frame;

[0033] The middle part of the connecting plate is connected to the outer bottom wall of the tipping cylinder, and the two ends of the connecting plate are rotatably connected to the bearing seat.

[0034] In this design, paired bearing seats are connected to the frame, providing a stable fulcrum for the tilting drum and ensuring its accuracy and stability when rotating around the bearing seats under the action of the lifting assembly. The middle part of the connecting plate is connected to the outer bottom wall of the tilting drum, and both ends are rotatably connected to the bearing seats, making the rotation of the tilting drum smoother and the force more even, effectively dispersing the force during the rotation of the tilting drum and preventing damage to components due to excessive local stress. At the same time, this connection structure strengthens the connection between the tilting drum and the frame, ensuring that even under the influence of large centrifugal forces, material impacts, and other external forces during the operation of the slurry filter, the tilting drum can be stably maintained in the correct position, maintaining the integrity and stability of the overall structure of the slurry filter, ensuring the reliable operation of slurry-sludge separation, and improving the durability of the slurry filter.

[0035] As a further technical solution for the slurry filter, the drive assembly is connected to the connecting plate, and the rotating shaft of the drive assembly extends into the tilting drum and is connected to the connecting seat on the rotating drum.

[0036] In this design, the drive assembly is connected to the connecting plate, which serves as a stable mounting base, ensuring the positional stability of the drive assembly during the operation of the pulp filter and reducing displacement caused by vibration and other factors. This ensures the stability and reliability of its output power. The rotating shaft of the drive assembly extends into the tilting drum and connects to the connecting seat on the drum, achieving efficient power transmission to the drum. This allows the drum to rotate synchronously and stably along its own axis under the drive of the drive assembly, along with the filter assembly. During rotation, the soybean milk flows out of the filter assembly under centrifugal force, achieving pulp and residue separation.

[0037] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0038] 1. The lifting components on both sides of the bottom of the frame of this utility model cooperate with the tilting cylinder connected to the top of the frame via bearing seats, allowing the tilting cylinder to rotate around the bearing seats and tilt at multiple angles. This facilitates the loading and unloading operations of the pulp filter. During feeding, the tilting cylinder can be adjusted to a suitable angle to facilitate the addition of the mixture of soybean milk and soybean residue. During discharge, the separated soybean milk and soybean residue can be easily discharged separately. Simultaneously, adjusting the tilt angle helps to ensure complete drainage of wastewater during cleaning, facilitating subsequent cleaning and maintenance of the equipment.

[0039] 2. The pulp filter of this utility model adopts a unique filter screen assembly, including a rotating drum, a filter screen and related support ring structures arranged sequentially from the inside to the outside. The filter screen is stably connected and supported by multiple sets of support rings and connecting components, ensuring that the filter screen is always in a taut state during operation and can be evenly stressed. At the same time, when the rotating drum rotates synchronously with the filter screen under the drive component, the soy milk can flow out through the filter screen more efficiently under the action of centrifugal force. Compared with the existing technology where the filter screen is easy to clog and the filtration is insufficient, the efficiency of pulp and residue separation is greatly improved.

[0040] 3. In this utility model, the scraper assembly has a scraper that contacts the inner wall of the filter screen assembly, and the soft brush further cleans the soybean residue remaining in the filter screen mesh. During the rotation of the filter screen assembly, the scraper assembly can promptly scrape off the soybean residue adhering to the filter screen, preventing the soybean residue from accumulating and clogging the filter screen, ensuring the continuous and good filtration performance of the filter screen, and making the pulp-residue separation process uninterrupted and efficient.

Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0054] Example 1

[0055] This embodiment 1 provides a drum-type soybean product filter, such as... Figures 1-2 As shown, the machine includes a frame 1 and a slurry filtering device. Lifting components 3 are provided on both sides of the bottom of the frame 1. Here, the lifting components 3 are motor devices that can realize linear reciprocating motion (telescopic action), such as telescopic motors or electric push rods. The slurry filtering device includes a tilting drum 5, a rotating drum 6, a filter screen assembly 7, and a scraper assembly 8.

[0056] Please refer to Figures 1-7 As shown, bearing seats 17 are connected to both sides of the middle part of the frame 1. The outer bottom wall of the tilting cylinder 5 is connected to the middle part of the connecting plate 23. The two ends of the connecting plate 23 are rotatably connected to the bearing seats 17 through bearings. The output end of the lifting assembly 3 is hinged to the first ear plate 4 near the opening end of the tilting cylinder 5. During the extension and retraction of the lifting assembly 3, the tilting cylinder 5 rotates around the bearing seat 17, thereby adjusting its tilt angle. A pulp inlet pipe 13 is provided at the upper opening of the tilting cylinder 5. The pulp inlet pipe 13 draws soy milk into the filter screen assembly 7 through the pulp supply pump 14. A pulp outlet pipe 15 is connected to the bottom wall of the tilting cylinder 5 to discharge the filtered soy milk. Here, since the tilting cylinder 5 is tilted when working, the pulp outlet pipe 15 is located at the lowest surface of the tilting cylinder 5 to ensure that the filtered pulp can be completely discharged.

[0057] Meanwhile, the filter assembly 7 and the rotating drum 6 are fitted into the tilting drum 5 and arranged sequentially from the inside to the outside. Filter holes are opened on both the filter assembly 7 and the rotating drum 6. The original soy milk in the filter assembly 7 enters the tilting drum 5 after being filtered twice and is collected and discharged from the soy milk outlet pipe 15.

[0058] The rotating drum 6 can drive the filter screen assembly 7 to rotate synchronously along its own axis through the drive assembly 16. At the same time, multiple sets of rollers 12 are evenly distributed along its own axis at the open end of the rotating drum 5. The outer wall of the rotating drum 6 is tangent to the outer wall of all the rollers 12. The rollers 12 provide stable support points for the rotating drum 6, so that the rotating drum 6 can maintain a stable operating state during rotation.

[0059] In this embodiment, the drive assembly 16 is connected to the connecting plate 23. The rotating shaft 21 of the drive assembly 16 extends into the tilting cylinder 5 and is connected to the connecting seat 25 on the rotating cylinder 6. The rotating shaft 21 and the connecting seat 25 can transmit power through a key or threaded connection. One end of the scraper assembly 8 is mounted at the opening of the tilting cylinder 5, and the other end of the scraper assembly 8 extends into the filter screen assembly 7 and slides against the inner wall of the filter screen assembly 7 to scrape off residual soybean residue in time, avoid clogging the filter screen 32, and thus ensure that the pulp and residue separation process continues to be carried out efficiently.

[0060] Please refer to Figure 3 As shown, the scraper assembly 8 includes a scraper body 18 and a scraper 19. The open end of the rotating drum 5 is provided with mounting posts 20 that match the scraper body 18. One end of the scraper 19 is connected to the scraper body 19, and the other end of the scraper 19 extends into the filter screen assembly 7 and abuts against the inner wall of the filter screen assembly 7. When the pulp filter is working, as the filter screen assembly 7 and the rotating drum 6 rotate, the scraper 19 can promptly scrape off the soybean residue adhering to the inner wall of the filter screen assembly 7, preventing the soybean residue from accumulating and clogging the filter screen 32, thus ensuring the filtration efficiency of the filter screen 32. Meanwhile, in some embodiments, such as... Figure 4 As shown, in order to further improve the cleaning effect of the filter screen 32, a soft brush is also provided on the side of the scraper 19 that contacts the filter screen assembly 7. The presence of the soft brush can more thoroughly clean the soybean residue remaining on the inner wall of the filter screen assembly 7.

[0061] Please refer to Figures 5-8 As shown, the filter assembly 7 includes a filter 32. The bottom of the inner cavity of the rotating cylinder 6 is connected to an installation ring 24. Correspondingly, the two ends of the filter 32 are respectively connected to a first support ring 27 and a fourth support ring 30. The first support ring 27 is connected to the rotating cylinder 6 through a connecting component. The fourth support ring 30 has a plurality of fourth ear plates 31 evenly distributed on it. The fourth ear plates 31 are connected to the installation ring 24 through fasteners. Of course, in order to quickly disassemble the filter assembly 7, the fourth support ring 30 and the installation ring 24 can also be connected by a quick-release connector.

[0062] Please also refer to Figures 1-2As shown, the above-mentioned connecting assembly includes multiple sets of fixing posts 9, a third ear plate 26, and a nut 10. The multiple sets of fixing posts 9 are evenly distributed and connected to the open end of the rotating drum 6. The third ear plate 26 is an annular support plate. The third ear plate 26 is connected to the fixing posts 9 and locked by the nut 10. The outer edge of the first support ring 27 is clamped to the third ear plate 26. The nut 10 is threadedly connected to the fixing posts 9 and presses against the third ear plate 26. This connection method is not only convenient for installation and disassembly, but also facilitates equipment maintenance and filter screen 32 replacement.

[0063] Example 2

[0064] This embodiment 2 provides another type of drum-type soybean product filter based on the technical solution of embodiment 1, such as... Figures 1-8 As shown, in order to enable this device to better adapt to the filtration requirements under different working conditions, in this embodiment, the filter screen 32 is a component made of flexible material. The filter screen 32 can be a polyester fiber mesh, a nylon mesh, or a polytetrafluoroethylene mesh. The above-mentioned connecting assembly also includes a spring 11. The spring 11 and the nut 10 are sequentially sleeved on the fixed post 9. The third ear plate 26 is connected between the spring 11 and the nut 10. In use, the spring 11 applies elastic force to the filter screen 32 to keep the filter screen 32 in a taut state.

[0065] Since the filter screen 32 is made of a flexible material, in order to enhance the structural strength and stability of the filter screen 32, the filter screen assembly 7 also includes a second support ring 28 and a third support ring 29. The second support ring 28 and the third support ring 29 are connected at intervals to the outer edge of the filter screen 32 and are located between the first support ring 27 and the fourth support ring 30, so as to prevent the filter screen 32 from being excessively deformed, wrinkled or damaged.

[0066] The usage process of this utility model:

[0067] 1. By activating the lifting components 3 on both sides of the bottom of the frame 1 via the control component 2 installed on the frame 1, the tilting cylinder 5 rotates around the bearing seat 17, adjusting the tilting cylinder 5 to a suitable tilt angle, generally a lower angle, to facilitate the flow of the mixture of soy milk and soy residue from the inlet pipe into the filtration device. For example, tilting the tilting cylinder 5 to 30°-45° with the horizontal plane ensures that the material can flow in smoothly without overflowing.

[0068] 2. Then, the control component 2 starts the slurry pump 14 to transport the mixture of soybean milk and soybean residue to the turning drum 5 through the slurry inlet pipe 13.

[0069] 3. Once the material inside the tipping drum 5 reaches a certain amount, the drive assembly 16 is activated. The rotating shaft 21 of the drive assembly 16 drives the rotating drum 6 to rotate. Since the rotating drum 6 and the filter screen assembly 7 are tightly connected through the connecting assembly, the filter screen assembly 7 also rotates synchronously. The outer wall of the rotating drum 6 is tangent to the roller 12 at the opening end of the tipping drum 5. The roller 12 provides stable support for the rotating drum 6, ensuring its smooth rotation.

[0070] 4. As the rotating drum 6 and filter assembly 7 rotate at high speed, the soy milk, under centrifugal force, flows through the mesh of the filter assembly 7 to the tilting drum 5 and is discharged and collected through the discharge pipe 15. The soy residue, due to its larger particle size, is blocked and retained inside the filter assembly 7 by the filter screen 32. The filter screen 32 in the filter assembly 7 is made of flexible material and is kept taut by the spring 11 and connecting components, ensuring even force distribution and effectively preventing deformation or clogging of the filter screen 32 due to uneven local force, thus ensuring a stable and efficient soy milk-residue separation process.

[0071] 5. During the rotation of the rotating drum 6 and the filter assembly 7, the scraper assembly 8 plays a role. The scraper body 18 is fixed to the open end of the rotating drum 5 by the mounting post 20. One end of the scraper 19 is connected to the scraper body 18, and the other end extends into the filter assembly 7 to abut against the inner wall. The soft brush on the contact surface between the scraper 19 and the filter 32 further penetrates into the filter mesh to clean the residual soybean residue. When the filter assembly 7 rotates, the scraper assembly 8 is relatively stationary, and the relative movement between the two causes the scraper 19 to scrape off the soybean residue adhering to the inner wall of the filter 32, preventing the soybean residue from accumulating and clogging the filter, and ensuring the filtration performance of the filter 32.

[0072] 6. The separated soy milk is continuously discharged through the discharge pipe 15 to the designated collection container. The operator can control the discharge speed of the soy milk according to actual production needs, for example, by adjusting the valve size on the discharge pipe 15 to control the flow rate.

[0073] 7. After the slurry filtering process is completed, stop the drive assembly 16 and adjust the tilting cylinder 5 to a lower angle (e.g., below the horizontal plane at a 30° or 60° angle) using the lifting assembly 3. Figure 9 As shown, the soybean residue is discharged from the opening of the tipping cylinder 5 into the soybean residue collection container under the action of gravity. During the discharge process, the tipping cylinder 5 can be rotated appropriately to ensure that the soybean residue is completely discharged.

[0074] 8. After feeding and discharging, use clean water to preliminarily rinse the inside of the slurry filter device through the slurry inlet pipe 13 to wash away any residual soybean milk and soybean residue. During the rinsing process, the tilting drum 5 and the filter screen assembly 7 can be rotated appropriately to make the cleaning more thorough.

[0075] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
