The centrifugation assembly is set inside the centrifuge 3 to improve the sedimentation rate of rice bran dietary fiber. The rinsing assembly is set inside the second fixing block 32 to rinse the centrifugation assembly. The filter press assembly is set inside the centrifuge 3 to facilitate the separation of dietary fiber and waste liquid. The collection assembly is set on the upper surface of the workbench 1 to collect dietary fiber and waste liquid separately.

[0035] In one embodiment, such as Figure 1 and Figure 2 As shown, the centrifugal assembly includes a first motor 8, a first rotating shaft 9, a first synchronous pulley 10, and a second synchronous pulley 11. The first motor 8 is fixedly connected to the upper surface of the workbench 1 via a bracket. The output end of the first motor 8 is fixedly connected to the first rotating shaft 9. The first synchronous pulley 10 is fixedly connected to the first rotating shaft 9. The second synchronous pulley 11 is fixedly connected to the circumferential side wall of the discharge pipe 36. The second synchronous pulley 11 and the first synchronous pulley 10 are driven by a synchronous belt. First, open the lid 4 and pour the pretreated rice bran solution, amylase, and alkali solution into the centrifuge cylinder 38. Close the lid 4, and the rotating ring 31 of the lid 4 contacts the upper surface of the centrifuge cylinder 38 to prevent the solution in the centrifuge cylinder 38 from splashing out during centrifugation and wasting some solution. Start the first motor 8, which drives the first rotating shaft 9 to rotate. The first rotating shaft 9 drives the first synchronous pulley 10 to rotate. The first synchronous pulley 10 drives the discharge pipe 36 to rotate through the synchronous belt. The discharge pipe 36 drives the filter press 19 to rotate. The filter press 19 drives the centrifuge cylinder 38 to rotate, thus performing the centrifugation operation, accelerating the precipitation of dietary fiber in the solution, and improving the precipitation rate and precipitation speed of dietary fiber.

[0036] In one embodiment, such as Figure 5As shown, the rinsing assembly includes a spray ring 29, a water tank 30, spray pipes 34, and an inlet pipe 40. A spray ring groove is formed on the lower surface of the second fixing block 32. A spray ring 29 is installed on the inner wall of the spray ring groove, and a water tank groove is formed on the inner wall of the spray ring groove. A water tank 30 is fixedly connected to the inner wall of the water tank groove. The water tank 30 is an annular box with an open lower surface. The water tank 30 is slidably connected to the upper surface of the spray ring 29. Several spray pipes 34 are fixedly connected through the spray ring 29. An inlet pipe 40 is fixedly connected through the inner top wall of the water tank 30, extending through to the outside of the tank cover 4.

A second rotating shaft 18 is rotatably connected to the top wall of the toothed ring cavity via a bearing. A third gear 33 is fixedly connected to one end of the second rotating shaft 18 located within the toothed ring cavity. The third gear 33 meshes with the toothed ring 35. The second rotating shaft 18 extends through the outer surface of the cover 4. A second motor 17 is fixedly connected to the upper surface of the cover 4 via a bracket. The output end of the second motor 17 is fixedly connected to the second rotating shaft 18. When the second motor 17 is started, it drives the second rotating shaft 18 to rotate, which in turn drives the third gear 33 to rotate. The third gear 33 then drives the toothed ring 35 to rotate, which in turn drives the water spray ring 29 to rotate. This causes the inner wall of the centrifuge cylinder 38 to be cleaned by rotating water spray, improving the cleaning effect and preventing residual dietary fiber from adhering to the inner wall of the centrifuge cylinder 38, thus avoiding waste.

[0038] In one embodiment, such as Figure 7 and Figure 8As shown, the filter press assembly includes a threaded rod 13, a threaded sleeve 14, a third synchronous pulley 15, a second baffle 24, a filter screen 28, and a filter press block 37. The threaded sleeve 14 is rotatably connected to the upper surface of the housing cover 4 via bearings. The third synchronous pulley 15 is fixedly connected to the circumferential side wall of the threaded sleeve 14. A fourth synchronous pulley 16 is fixedly connected to a section of the second rotating shaft 18 located outside the housing cover 4. The third synchronous pulley 15 and the fourth synchronous pulley 16 are driven by a synchronous belt. The threaded sleeve 14 is threaded with threaded... The rod 13 has a filter block groove on its lower surface. A filter block 37 is slidably connected to the inner wall of the filter block groove. The size of the filter block 37 is the same as the size of the hole in the filter press box 19.

The fourth synchronous pulley 16 drives the third synchronous pulley 15 to rotate through the synchronous belt. The third synchronous pulley 15 drives the threaded sleeve 14 to rotate. The threaded sleeve 14 drives the threaded rod 13 to descend. The threaded rod 13 drives the filter block 37 to descend. The filter block 37 filters the dietary fiber on the filter screen 28, thereby increasing the filtration speed of the dietary fiber.

[0039] In one embodiment, such as Figure 2 and Figure 3 As shown, a first fixing block 5 is fixedly connected to the upper surface of the box cover 4, and a limiting block 12 is fixedly connected to the upper surface of the threaded rod 13. A limiting block groove is formed on the side wall of the first fixing block 5, and the limiting block 12 is slidably connected to the inner side wall of the limiting block groove. A limiting block 12 is provided at the top of the threaded rod 13. The first fixing block 5 limits the limiting block 12, so that it can only slide up and down, preventing the threaded rod 13 from rotating during the descent process, which would affect the descent of the threaded rod 13.

[0040] In one embodiment, such as Figure 8 and Figure 9As shown, a fourth motor slot is provided inside the filter press 19. A fourth motor 26 is fixedly connected to the inner side wall of the fourth motor slot. A fourth rotating shaft 27 is rotatably connected to the bottom wall of the fourth motor slot through a bearing. The second baffle 24 is slidably connected to the inner side wall of the second baffle slot. The output end of the fourth motor 26 is fixedly connected to the fourth rotating shaft 27. The fourth rotating shaft 27 extends through into the second baffle slot. A second gear 25 is fixedly connected to one end of the fourth rotating shaft 27 located in the second baffle slot. A second rack 42 is fixedly connected to the side wall of the second baffle 24. The second gear 25 meshes with the second rack 42. When the fourth motor 26 is started, the fourth motor 26 drives the fourth rotating shaft 27 to rotate. The fourth rotating shaft 27 drives the second gear 25 to rotate. The second gear 25 drives the second baffle 24 to move through its interaction with the second rack 42. During the movement of the second baffle 24 into the second baffle slot, the side wall of the second baffle slot scrapes off the dietary fiber on the filter screen 28.

[0041] In one embodiment, such as Figure 8 and Figure 9 As shown, a first baffle groove is provided inside the filter press 19. A first baffle 20 is slidably connected to the inner side wall of the first baffle groove. A first rack 41 is fixedly connected to the side wall of the first baffle 20. The first baffle 20 is located at the hole position of the filter press 19. A third motor groove is provided inside the filter press 19. A third motor 21 is fixedly connected to the inner side wall of the third motor groove. A third rotating shaft 22 is fixedly connected to the output end of the third motor 21. The third rotating shaft 22 is rotatably connected to the top wall of the third motor groove through a bearing. The third rotating shaft 22 extends through into the first baffle groove. A first gear 23 is fixedly connected to one end of the third rotating shaft 22 located in the first baffle groove. The first gear 23 meshes with the first rack 41. After sedimentation is complete, the third motor 21 is started. The third motor 21 drives the third rotating shaft 22 to rotate. The third rotating shaft 22 drives the first gear 23 to rotate. The first gear 23 drives the first baffle 20 to move, so that the first baffle 20 no longer blocks the hole of the filter press 19.

[0042] In one embodiment, such as Figure 2 and Figure 3 As shown, the collection assembly includes an electric push rod 6 and a dispensing box 7. The electric push rod 6 is fixedly connected to the upper surface of the workbench 1, and the dispensing box 7 is fixedly connected to the output end of the electric push rod 6. A slider 39 is fixedly connected to the lower surface of the dispensing box 7. A slider groove is provided on the upper surface of the workbench 1, and the slider 39 is slidably connected to the inner wall of the slider groove. The dispensing box 7 is a box with an open top wall, and two collection boxes with open top walls are detachably installed inside the dispensing box 7. Waste liquid falls into one of the collection boxes of the dispensing box 7, and dietary fiber falls into the other collection box.

[0043] In one embodiment, such as Figure 5As shown, a rotating ring groove is formed on the lower surface of the second fixing block 32. A rotating ring 31 is rotatably connected to the inner wall of the rotating ring groove via a bearing. The rotating ring 31 abuts against the upper surface of the centrifuge cylinder 38. When the lid 4 is closed, the rotating ring 31 of the lid 4 contacts the upper surface of the centrifuge cylinder 38 to prevent the solution inside the centrifuge cylinder 38 from splashing out during centrifugation and causing some solution waste.

[0044] The above embodiment discloses a rice bran dietary fiber screening device. First, open the box cover 4, pour the pretreated rice bran solution, amylase, and alkali solution into the centrifuge cylinder 38, close the box cover 4, and the rotating ring 31 of the box cover 4 contacts the upper surface of the centrifuge cylinder 38 to prevent the solution in the centrifuge cylinder 38 from splashing out during centrifugation and wasting some solution. Start the first motor 8, the first motor 8 drives the first rotating shaft 9 to rotate, the first rotating shaft 9 drives the first synchronous pulley 10 to rotate, the first synchronous pulley 10 drives the discharge pipe 36 to rotate through the synchronous belt, the discharge pipe 36 drives the filter press 19 to rotate, the filter press 19 drives the centrifuge cylinder 38 to rotate, and perform centrifugation operation to accelerate the precipitation of dietary fiber in the solution and improve the precipitation rate and precipitation speed of dietary fiber.

[0045] After complete sedimentation, the third motor 21 is started. The third motor 21 drives the third rotating shaft 22 to rotate, which in turn drives the first gear 23 to rotate. The first gear 23 drives the first baffle 20 to move, so that the first baffle 20 no longer blocks the holes of the filter press 19, allowing the solution to enter the holes of the filter press 19. The filter screen 28 filters the dietary fiber in the solution. The waste liquid flows out from the discharge pipe 36 and into one of the collection boxes in the distribution box 7. Water is poured into the water tank 30 from the water inlet pipe 40, and water is sprayed out from the water spray pipe 34 to clean the inner wall of the centrifuge cylinder 38. The second motor 17 is started. The second motor 17 drives the second rotating shaft 18 to rotate, which in turn drives the third gear 33 to rotate. The third gear 33 drives the gear ring 35 to rotate, which in turn drives the water spray ring 29 to rotate. This causes the inner wall of the centrifuge drum 38 to be cleaned by rotating water spray, improving the cleaning effect and preventing residual dietary fiber from adhering to the inner wall of the centrifuge drum 38 and causing waste. Simultaneously, the second rotating shaft 18 drives the fourth synchronous pulley 16 to rotate, which in turn drives the third synchronous pulley 15 to rotate via a synchronous belt. The third synchronous pulley 15 drives the threaded sleeve 14 to rotate, which in turn causes the threaded rod 13 to descend. The top of the threaded rod 13 is equipped with... Limiting block 12 and first fixing block 5 limit the limiting block 12, allowing it to slide only up and down, preventing the threaded rod 13 from rotating during descent and affecting its descent. The threaded rod 13 drives the filter press block 37 to descend, and the filter press block 37 filters the dietary fiber on the filter screen 28, increasing the filtration speed of the dietary fiber. During this process, the water spray pipe 34 sprays water for only a short time, cleaning the filter press block 37 before it enters the hole of the filter press box 19. After filtration is completed, the electric push rod 6 is activated, which moves the material distribution box 7, moving another collection box directly below the discharge pipe 36. The fourth motor 26 drives the fourth rotating shaft 27 to rotate, which in turn drives the second gear 25 to rotate. The second gear 25, in conjunction with the second rack 42, drives the second baffle 24 to move. As the second baffle 24 moves into the second baffle groove, the side wall of the second baffle groove scrapes off the dietary fiber on the filter screen 28, which falls through the holes of the discharge pipe 36 into another collection box of the distribution box 7, thus completing the screening of dietary fiber. After centrifugation, the fiber is directly filtered, eliminating the need to transport the precipitate solution after centrifugation to other places for filtration, and avoiding the waste of dietary fiber caused by changing containers during transportation.

[0046] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
