[0002] In the food processing industry, especially in the production of oat products, purification and separation are key steps. Traditional separation methods, such as centrifugation or filtration, are widely used in routine operations, but they have many shortcomings, such as limited processing capacity, high energy consumption, and potential loss of valuable active ingredients. In particular, when preparing oat peptides, it is necessary to retain their biological activity and functionality, and traditional separation methods are difficult to meet this requirement.

[0003] Nanofiltration membrane technology, as a highly efficient separation and purification method, has shown significant advantages in liquid separation and concentration. It can retain substances of specific molecular weights through a semi-permeable membrane, and is particularly effective for the separation and purification of proteins and peptides. The nanofiltration process is characterized by low energy consumption and environmental friendliness, and can effectively remove impurities such as inorganic salts while maintaining a large flux, which is extremely important for high value-added products such as oat peptides.

[0004] The existing fully automated nanofiltration membrane system for oat peptide production requires multiple drive structures to operate simultaneously. These drive structures generate vibrations during simultaneous operation, which necessitates frequent inspection and maintenance of the device's connection points by staff. This increases the operating cost of the device and reduces its stability during use. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0034] Example 1

[0035] This invention provides a fully automated nanofiltration membrane system for oat peptide production, such as... Figures 1 to 5As shown, the assembly includes: a bottom frame 1, a fixing component, and a transmission component. The fixing component includes a mounting frame 2, a mounting plate 3, and a shelf 8. The mounting frame 2 is connected to the bottom frame 1 and houses a filtration device. The mounting frame 2 is located inside the frame. The mounting plate 3 is connected to the mounting frame 2, and a drive structure is located above the mounting plate 3. The drive structure consists of a high-pressure feed pump, a circulation pump, and an electric regulating valve, and all three drive structures are connected to the connecting pipe 7. The shelf 8 is connected to the bottom frame 1. The transmission component includes a filter element 4, a connecting pipe 7, and a control component 10. The filter element 4 is connected to the shelf 8, and the shelf 8 has three separate placement areas. There are three filter elements 4, each installed in one of the three separate placement areas. All three filter elements 4 are nanofiltration membrane elements of spiral wound membrane type. The connecting pipe 7 is connected to the filter element 4, and the control component 10 is connected to the filter element 4. The control component 10 is a valve, and the valve can be equipped with a discharge pipe. The system includes a collection tank for collecting liquid; the transmission assembly also includes a pressure gauge 5 connected to a connecting pipe 7, the pressure gauge 5 being connected to the connecting pipe 7 and passing through the interior of the connecting pipe 7, and both the pressure gauge 5 and the connecting pipe 7 are equipped with a sealing structure to avoid inaccurate pressure detection by the pressure gauge 5 in the connecting pipe 7; a mounting base 6 is connected to the connecting pipe 7 and the shelf 8, and the mounting base 6 is located above the shelf 8; a mounting block 9 is connected to the connecting pipe 7 and the shelf 8, and the mounting block 9 is located on one side of the shelf 8; the mounting base 6 and the mounting block 9 are used to position the connecting pipe 7 to make it more stable; the connecting pipe 7 also includes the same number of branch pipes as the filter element 4, the branch pipes are L-shaped, and the number is set to three, the three different branch pipes are respectively embedded and connected to different filter elements 4, and the other pipe of each of the three branch pipes is embedded and connected to the same connecting pipe 7; the fully automatic nanofiltration membrane filtration system for oat peptide production also includes a PLC control cabinet, which controls the filter element 4 and the drive structure to operate according to the set state during use.

[0036] By mounting the drive structure on the top of the mounting plate 3 and positioning the connecting pipe 7 on the surface of the shelf 8, the device becomes more stable during use. Furthermore, the connection strength between the mounting plate 3, the mounting frame 2, and the bottom frame 1 minimizes the impact of vibrations generated during the operation of the drive structure on these components, thus preventing wobbling during operation and improving the stability of the drive structure during use.

[0037] In use, the bottom frame 1, mounting bracket 2, mounting plate 3, and drive structure are assembled together with screws. Then, by activating the control unit 10, the drive structure draws the material to be filtered into the connecting pipe 7, causing the liquid to flow along the inside of the connecting pipe 7 under the drive of the drive structure. At this time, because the liquid is flowing inside the connecting pipe 7, the flow process is more stable due to the restriction of the connecting pipe 7 by the mounting seat 6 and the mounting block 9. Subsequently, the operator observes the pressure value inside the connecting pipe 7 by observing the pressure gauge 5. This liquid enters the filter element 4 for filtration along the connecting pipe 7. The flow process is more stable due to the restriction of the connecting pipe 7 by the mounting seat 6 and the mounting block 9. Subsequently, the operator observes the pressure value inside the connecting pipe 7 by observing the pressure gauge 5, which makes it easy for the operator to observe.

[0038] In the above example, specifically, the mounting bracket 2 is installed on the top of the bottom frame 1 with screws, the mounting plate 3 is installed on the top of the mounting bracket 2 with screws, the drive structure is installed on the top of the mounting plate 3 with screws, the shelf 8 is fixedly connected to the top edge of the bottom frame 1, the filter element 4 is installed inside the shelf 8 with screws, the mounting base 6 is fixedly connected to the top of the shelf 8, the mounting block 9 is fixedly connected to the side of the shelf 8, the pressure gauge 5 is embedded in the connecting pipe 7, and the control element 10 is fixedly connected to the surface of the filter element 4.

[0039] In the above examples, both the filter element 4 and the drive structure are existing technologies in this field, and will not be described in detail here.

[0040] like Figures 3 to 5 As shown, the transmission assembly also includes a cleaning assembly, which includes a positioning frame 11, a rotating shaft 12, a baffle 13, a ring 14, and a cleaning component 15. The positioning frame 11 is connected to the connecting pipe 7. The rotating shaft 12 is connected to the positioning frame 11. The positioning frame 11 is cross-shaped, and a groove is provided at the junction of the cross-shaped positioning frame 11. A bearing is fitted into the groove. The positioning frame 11 is located on both sides of the rotating shaft 12. The edges of both sides of the rotating shaft 12 are fitted into the bearing. The baffle 13 is connected to the rotating shaft 12, and a gap is left between the baffle 13 and the positioning frame 11. The ring 14 is connected to the baffle 13 and the connecting pipe 7. The ring 14 is in contact with the inner wall of the connecting pipe 7. The cleaning component 15 is connected to the ring 14 and is located between two opposing rings 14. The cleaning component 15 can be a wear-resistant structure such as a scraper or scraper that can remove residue from the inner wall. Both the baffle 13 and the cleaning component 15 are arranged in a circumferential array with the center of the side of the rotating shaft 12. Both ends of the rotating shaft 12 are connected to conical blocks, which limit the rotation of the rotating shaft 12 to make it more stable. The baffle 13 is spiral in shape so that the flowing liquid can drive the spiral baffle 13 to rotate. The surface of the cleaning component 15 is in contact with the inner wall of the connecting pipe 7.

[0041] During use, the liquid flows inside the connecting pipe 7 and rotates along the spiral shape of the baffle 13. At this time, the baffle 13 will rotate, which drives the rotating shaft 12 and the ring 14 to rotate. During the rotation of the rotating shaft 12, the positioning frame 11 restricts its rotation to make it more stable. The ring 14 drives the cleaning component 15 to rotate. During the rotation of the cleaning component 15, the impurities remaining on the inner wall of the connecting pipe 7 are cleaned, thereby making the inner wall of the connecting pipe 7 cleaner and avoiding the problem of residual liquid clumping on the inner wall of the connecting pipe 7.

[0042] By using this device to clean the inner wall of the connecting pipe 7, the cleanliness of the device is improved, preventing the presence of uncleaned impurities inside the connecting pipe 7 when the device is not in use. This also prevents these residual impurities from caking on the inner wall of the connecting pipe 7, thus ensuring that the connecting pipe 7 is always in good working condition.

[0043] As in the specific example above, the positioning frame 11 is fixedly connected to the inner wall of the connecting pipe 7, the rotating shaft 12 is rotatably connected to the inside of the positioning frame 11, the baffle 13 is fixedly connected to the outer surface of the rotating shaft 12, the ring 14 is fixedly connected to both sides of the baffle 13, and the two cleaning parts 15 are respectively fixedly connected to two different rings 14 at both ends.

[0044] Working principle: When using this device, the operator first activates the drive structure, which draws the material to be filtered into the connecting pipe 7. The liquid flows along the connecting pipe 7 under the drive of the drive structure. The flow is stabilized by the mounting base 6 and mounting block 9. The operator then monitors the pressure inside the connecting pipe 7 using pressure gauge 5. The filtered liquid then enters the filter element 4 for filtration. The operator installs the discharge pipe on the control element 10 and opens it to discharge the filtered liquid from the filter element 4. The reinforced bottom frame 1, mounting bracket 2, and mounting plate 3 ensure stable operation of the drive structure. The pressure gauge 5 monitors the pressure inside the connecting pipe 7, allowing the operator to monitor the device's status in real time, thus improving its stable operation.

[0045] As the liquid flows inside the connecting pipe 7, it rotates along the spiral shape of the baffle 13. At this time, the baffle 13 will rotate, which drives the rotating shaft 12 and the ring 14 to rotate. During the rotation of the rotating shaft 12, the positioning frame 11 restricts its rotation, making it more stable. The ring 14 drives the cleaning component 15 to rotate. During the rotation of the cleaning component 15, the impurities remaining on the inner wall of the connecting pipe 7 are cleaned, making the inner wall of the connecting pipe 7 cleaner and thus avoiding the problem of residual liquid clumping on the inner wall of the connecting pipe 7.

[0046] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
