It can be used as an immune enhancer or regulator, and has antiviral, anti-tumor, anti-aging, anti-radiation, anti-stress and antioxidant effects. At present, the extraction of Astragalus polysaccharide mostly uses water boiling and alcohol precipitation, alcohol alkali, microwave, ultrafiltration, cellulase and other extraction methods; among them, compared with other extraction methods, the water boiling and alcohol precipitation method has lower cost and is therefore more widely used.

The structure is simple, the cleaning of the filter plate 303 is convenient, and the practicability is high.

[0026] like Figure 1 , Figure 2 and Figure 5As shown, a connecting frame 304 is fixedly connected to the top of the filter housing 301 near the middle position, a rotating frame 305 is fixedly connected to the top center of the connecting frame 304, a connecting rod 306 is rotatably connected between the inner surface walls of the rotating frame 305, a connecting shaft 308 is rotatably connected to the top of the connecting rod 306, a rotating disk 307 is fixedly connected to the right end of the connecting shaft 308 and the connecting shaft 308 is located at the surface edge of the rotating disk 307, a first rotating shaft 309 is fixedly connected to the center of the right surface of the rotating disk 307, a first bevel gear 310 is fixedly connected to the right end of the first rotating shaft 309, the first bevel gear 310 is meshed with the second bevel gear 605, and the outer surface of the first rotating shaft 309 rotates and penetrates the L-shaped frame 601 When the second bevel gear 605 rotates, it will drive the first bevel gear 310 to rotate.

Finally, the valve on the discharge pipe 504 can be opened to discharge and collect it. In the whole process, only one motor 606 is needed to provide power for the filtering mechanism 3, the stirring mechanism 4 and the centrifugal mechanism 5, which can effectively reduce the overall complexity and cost of the device, and the difficulty of later maintenance is low, and the overall practicality is high.

[0029] The method of use and working principle of the device are as follows: when in use, the boiled astragalus solution is poured into the interior of the feed channel 2, and the astragalus solution will enter the internal filter shell 301, and the three-layer filter plate 303 in the second slot 302 on the inner wall of the filter shell 301 will filter the impurities in the astragalus solution multiple times according to their size, and the filtered astragalus solution will pass through the discharge shell 22 below and enter the subsequent stirring barrel 401.

The filter shell 301 at the bottom of the connecting frame 304 can only move up and down inside the feed channel 2. Therefore, it will drive the internal filter plate 303 to reciprocate up and down under the action of the driving mechanism 6, thereby preventing impurities from being stationary in the filter The plate 303 is blocked, which improves the filtering effect. After the filtered astragalus solution enters the stirring barrel 401, the second rotating shaft 404 will follow the bottom end of the fourth rotating shaft 603 inside the driving mechanism 6 to rotate at a high speed, so that the astragalus solution is evenly stirred through the stirring blades 405 on the surface, which helps the mass transfer process in the solution, so that the astragalus polysaccharide molecules, solvents, additives, etc. can be quickly distributed in the solution, which is convenient for subsequent separation operations. When the astragalus solution is stirred, the valve on the surface of the discharge pipe 403 is opened, and the solution inside the stirring barrel 401 will be concentrated to the position of the discharge pipe 403 through the conical bottom 402 and enter the filter cartridge 502 below through the discharge pipe 403. When the evenly stirred astragalus solution enters After reaching the filter cartridge 502, the rotation of the second rotating shaft 404 will synchronously drive the third rotating shaft 503 to rotate.

Finally, the valve on the discharge pipe 504 can be opened to discharge and collect it. In the whole process, only one motor 606 is needed to provide power for the filtering mechanism 3, the stirring mechanism 4 and the centrifugal mechanism 5, which can effectively reduce the overall complexity and cost of the device, and the difficulty of later maintenance is low, and the overall practicality is high.
