Description

Technical Field

[0001] This utility model relates to the field of flavonoid extract precipitation technology, specifically to a stepwise precipitation device for bitter bean flavonoid extract. Background Technology

[0002] Bitter bean flavonoid extract is a type of natural plant extract with flavonoids as its core active ingredient, refined from the dried aerial parts of the legume bitter bean through modern extraction and separation technology. Compared with traditional bitter bean extract, which mainly contains alkaloids, flavonoid extract focuses on another major class of active ingredients, with different physiological activities and application characteristics, relatively lower toxicity, and higher safety.

[0003] Currently, the extraction of flavonoids from bitter bean seeds mostly employs the alkaline extraction and acid precipitation method. This involves extraction under alkaline conditions, followed by gradual adjustment of the pH value to acidity, causing the flavonoid compounds to precipitate out in steps. In the traditional stepwise precipitation process, each pH adjustment requires precise control of the pH value, followed by filtration in another container to separate the precipitate. This process is repeated multiple times, involving changing containers and filter membranes to separate flavonoid components with different solubilities. This process is cumbersome, time-consuming, and labor-intensive, and can easily lead to sample loss or cross-contamination, affecting not only extraction efficiency and product purity but also resulting in low extraction efficiency.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] See attached document Figures 1-4 A stepwise precipitation device for bitter bean flavonoid extract includes a mounting base 1, a support rod 2 mounted on the top of the mounting base 1, a first support plate 3 and a second support plate 4 respectively fitted onto the surface and bottom of the support rod 2, a first beaker 5 and a second beaker 6 respectively mounted on the top of the first support plate 3 and the second support plate 4, a filter mechanism mounted on the top of the second beaker 6, and a pipette 7 mounted on the top of the second beaker 6. By adjusting the positions of the first support plate 3 and the second support plate 4, a height difference exists between the first beaker 5 and the second beaker 6 after placement, allowing for the filtration of the extract through a siphon. Using the siphon principle, the liquid in the first beaker 5 is transferred to the second beaker 6 through the pipette 7. The liquid can then be filtered by the filtration mechanism. It is worth noting that the tops of the first support plate 3 and the second support plate 4 are equipped with restraints to limit the first beaker 5 and the second beaker 6, preventing them from being misaligned or falling during use. Through the siphon principle and the design of containers with different heights, the automatic transfer and filtration of precipitates under different pH conditions is achieved, avoiding repeated container switching, simplifying the operation process, and improving the efficiency and purity of precipitation separation.

[0026] The filtration mechanism includes a mounting frame 8, which is installed on the top of the second beaker 6. A filter membrane 9 is installed on the inner wall of the mounting frame 8, and an interface 10 is connected to the side of the mounting frame 8. The solution that produces precipitate can be introduced into the second beaker 6 with the filter membrane 9 installed through a pipette 7. After filtration, the filter membrane 9 can be removed to separate the precipitate.

[0027] See attached document Figure 1 The surface of the support rod 2 is fitted with a movable ring 11, and an extension frame 12 is installed on the surface of the movable ring 11. A notch 13 is opened on the front of the extension frame 12, and the pipette 7 is located inside the notch 13. The pipette 7 can be restricted in the notch 13. The extension frame 12 restricts the pipette 7 to prevent it from deviating during use.

[0028] See attached document Figure 1The surface of the support rod 2 is fitted with a first mounting sleeve 14, a second mounting sleeve 15, and a third mounting sleeve 16 from top to bottom. The second mounting sleeve 15 and the third mounting sleeve 16 are located at the bottom of the first support plate 3 and the second support plate 4, respectively. A connecting block 17 is installed on the surface of the first mounting sleeve 14. A snap-fit ​​bracket 18 is installed at the end of the connecting block 17. A pH meter 19 is snapped into the inner wall of the snap-fit ​​bracket 18. The pH meter 19 is located at the top of the first beaker 5. The snap-fit ​​bracket 18 can be installed through the connecting block 17, and the pH meter 19 can be installed through the snap-fit ​​bracket 18, so that the pH meter 19 can be inserted into the first beaker 5. The pH meter 19 can be used to detect the acidity or alkalinity of the liquid in the first beaker 5.

[0029] See attached document Figures 1-2 The first mounting sleeve 14, the second mounting sleeve 15, and the third mounting sleeve 16 are all equipped with a first connecting bracket 20 on their sides. A limiting rod 21 is inserted into the side of the first connecting bracket 20, and a fitting block 22 is installed at the end of the limiting rod 21. The sides of the first mounting sleeve 14, the second mounting sleeve 15, and the third mounting sleeve 16 are all provided with through grooves 23, and the fitting block 22 extends into the interior of the through groove 23. A fixing block 24 is installed on the inner wall of the first connecting bracket 20, and an installation groove 25 is installed inside the fixing block 24. A first spring is installed on the inner wall of the installation groove 25. Spring 26, the end of the first spring 26 is equipped with a limiting block 27, the surface of the limiting rod 21 is provided with a limiting groove 28, the limiting block 27 is engaged with the limiting groove 28, by moving the fitting block 22 to the position of fitting with the surface of the frame rod 2, the first spring 26 squeezes the limiting block 27, pushes the limiting block 27 into the limiting groove 28 to limit the limiting rod 21, so that the fitting block 22 can stably fit with the surface of the frame rod 2, thereby limiting the first mounting sleeve 14, the second mounting sleeve 15 and the third mounting sleeve 16.

[0030] See attached document Figures 1-4A second connecting frame 29 is provided on the top of the first beaker 5. A limiting ring 30 is fixedly installed at the end of the second connecting frame 29. Fitting rings 31 are installed at both the top and bottom of the limiting ring 30. A moving rod 32 is inserted into the inside of the second connecting frame 29. A pressing block 33 is installed on the surface of the moving rod 32. A fitting plate 34 is slidably installed on the inner wall of the second connecting frame 29, located at the bottom of the pressing block 33. This allows the side of the second connecting frame 29 with the limiting ring 30 to be placed inside the first beaker 5, so that the fitting rings 31 can... The moving rod 32 is able to fit against the inner wall of the first beaker 5, and when it is squeezed downward, it drives the squeezing block 33 to move and squeeze the fitting plate 34. This allows the fitting plate 34 to be inserted into the pipette 7 inside the limiting ring 30 and the fitting ring 31, thus preventing the pipette 7 from falling off when the liquid is aspirated. An extension plate is installed on the side of the fitting plate 34, and a second spring is installed on the side of the extension plate. When the second spring squeezes the extension plate, it causes the extension plate to move the fitting plate 34 back to its original position, thus releasing the restriction on the pipette 7.

[0031] In addition, a movable block 35 is inserted into the side of the second connecting frame 29, and a plug-in rod 36 is installed at the bottom of the inner wall of the second connecting frame 29. The plug-in rod 36 is inserted into the movable rod 32. A rotating block 37 is installed at the bottom of the movable rod 32. When the movable rod 32 is moved downward, the rotating block 37 and the movable block 35 are kept on the same horizontal plane. When the movable rod 32 is rotated, the rotating block 37 squeezes the movable block 35, so that the side of the movable block 35 is in contact with the surface of the first beaker 5, thereby restricting the second connecting frame 29 and thus restricting the pipette 7.

[0032] Working principle: The limiting rod 21 at the second mounting sleeve 15 is moved away from the support rod 2, releasing the restriction on the second mounting sleeve 15. This allows the height of the first support plate 3 to be adjusted, enabling the pH meter 19 to be inserted into the first beaker 5 for pH measurement. Then, by pressing the limiting rod 21 on the side of the second mounting sleeve 15, the fitting block 22 at the end of the limiting rod 21 is brought into contact with the surface of the support rod 2. When the fitting block 22 is in contact with the support rod 2, the limiting block 27 is inserted into the limiting groove 28 to restrict the limiting rod 21, thus limiting the angle and height of the first support plate 3. Similarly, the limiting rod 21 at the third mounting sleeve 16 is pulled out, adjusting the distance between the second support plate 4 and the first support plate 3 to maintain a distance of 50 cm. This allows the first beaker 5 and the second... Beaker 6 is placed above the first support plate 3 and the second support plate 4 respectively. Then, the lower end of pipette 7 is connected to the mounting bracket 8, and the upper end of pipette 7 passes through the limiting ring 30 and the fitting ring 31, extending the upper end of pipette 7 into the interior of the first beaker 5. After inserting pipette 7 into the first beaker 5, the moving rod 32 is pressed down and rotated, so that the moving rod 32 moves downward, causing the squeezing block 33 and the rotating block 37 to move downward. When the squeezing block 33 moves downward, it can squeeze the fitting plate 34, so that the fitting plate 34 restricts the pipette 7 in the limiting ring 30. When the moving rod 32 is rotated, it can drive the rotating block 37 to squeeze the moving block 35, so that the moving block 35 is in contact with the surface of the first beaker 5, thereby restricting the second connecting bracket 29 and restricting the pipette 7 to prevent it from falling.

[0033] After the pipette 7 is inserted into the first beaker 5, the pipette rod can use the siphon principle and the misalignment of the first beaker 5 and the second beaker 6 to draw the liquid in the first beaker 5 into the filter membrane 9 in the second beaker 6. The filter membrane 9 then filters the liquid. After filtration, the filter membrane 9 is removed and separated for precipitation. Then, the acid adjustment and precipitation are carried out in a new container. This process is repeated until no precipitate is formed in the alkaline waste liquid.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
