Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] By using an input pipe 2 to respectively arrange a liquid inlet 3 and a feed inlet 4, the organic solvent and the plant raw material can be mixed when injected into the inside of the stirring barrel 1, reducing the later stirring and mixing time. By setting the stirring assembly 5, the stirring efficiency can be increased and the stirring time can be reduced. By the filtering assembly 9, the residue in the liquid containing lutein can be quickly filtered, and it is convenient to clean the filtering assembly 9.

[0026] Please refer to Figure 2 , Figure 3, the stirring assembly 5 includes a first motor 501, the first motor 501 is fixedly connected to the upper surface of the stirring barrel 1, the output end of the first motor 501 penetrates into the interior of the stirring barrel 1 and is fixedly connected with a square rod 502, a fixed tube 503 is sleeved on the surface of the square rod 502, the upper surface of the fixed tube 503 is fixedly connected to the upper inner wall of the stirring barrel 1, a first extrusion block 504 is fixedly connected to the lower end of the square rod 502, a second extrusion block 505 is movably connected below the first extrusion block 504, a stirring rod 506 is fixedly connected to the lower surface of the second extrusion block 505, a square hole 507 is formed in the upper part inside the upper part of the stirring rod 506, the square rod 502 sequentially passes through the first extrusion block 504, the second extrusion block 505 and the square hole 507 and is movably connected, the square rod 502 is movably connected with the first extrusion block 504 and the second extrusion block 505, two extrusion plates 508 are fixedly connected to the lower part of the surface of the stirring rod 506, and stirring blades 512 are fixedly connected to the surface of the stirring rod 506 above the extrusion plates 508.

When the surfaces of the first extrusion block 504 and the second extrusion block 505 that are close to each other coincide, under the action of the spring 511, the connecting plate 509 is squeezed to move upward, and the upper extrusion plate 508 is pushed to move upward, thereby driving the stirring rod 506 to move upward, and then driving the stirring blades 512 to move upward, realizing the simultaneous up and down movement while the stirring blades 512 are stirring, greatly shortening the mixing time of the plant raw materials and the organic solvents, and enabling lutein to be quickly dissolved into the organic solvents.

[0029] Please refer to Figure 4 , Figure 5 , Figure 6 , Figure 7, the filtering component 9 includes a support frame 901. In the middle of the rear side of the upper surface of the support frame 901, a transmission box 902 is fixedly connected. On the upper surface of the transmission box 902, a second motor 903 is fixedly connected. The output end of the second motor 903 penetrates into the interior of the transmission box 902 and is fixedly connected to a lead screw 904. The lower end of the lead screw 904 is rotatably connected to the transmission box 902. Inside the transmission box 902, a reinforcing rod 905 is fixedly connected at the rear side of the lead screw 904. A connecting block 906 is threadedly connected to the surface of the lead screw 904. The rear side of the connecting block 906 is slidably connected to the reinforcing rod 905. The outer wall of the connecting block 906 is movably connected to the inner wall of the transmission box 902. At the front side of the connecting block 906, a third motor 907 is fixedly connected.

[0030] The output end of the third motor 907 is fixedly connected with a plurality of connecting feet 909 in an annular array. Inside the lower part of each of the plurality of connecting feet 909, a mounting bolt 913 is rotatably connected. Below the connecting feet 909, a filter hopper 908 is provided. The filter hopper 908 is located below the second drain pipe 8. Above the outer surface of the filter hopper 908, a rotating frame 910 is rotatably connected. On the opposite sides of the surface of the rotating frame 910, limiting blocks 911 are fixedly connected. Above the interior of the filter hopper 908, a fixing plate 912 is fixedly connected. The fixing plate 912 is threadedly connected to the plurality of mounting bolts 913.

[0031] In the middle of the lower surface of the filter hopper 908, a limiting rod 914 is fixedly connected.

[0032] On the upper surface of the support frame 901, in front of the transmission box 902, a liquid storage bucket 919 is fixedly connected. The inner wall of the liquid storage bucket 919 is in contact with the outer wall of the rotating frame 910. Inside the liquid storage bucket 919, a support plate 915 is fixedly connected. In the middle of the support plate 915, a rotating hole 916 penetrating the upper and lower surfaces is provided. The rotating hole 916 is rotatably connected to the limiting rod 914. On the surface of the liquid storage bucket 919, below the filter hopper 908, a liquid outlet pipe 917 is connected through. On the opposite sides inside the liquid storage bucket 919, limiting grooves 918 are provided. The two limiting grooves 918 are respectively slidably connected to the two limiting blocks 911.

[0033] When the mixture containing lutein to be filtered is discharged into the interior of the filter hopper 908, the connecting feet 909 below are driven to rotate by the third motor 907, and then the fixing plate 912 is driven to rotate. When the fixing plate 912 rotates, it will drive the filter hopper 908 to rotate inside the rotating frame 910. When the filter hopper 908 rotates, the mixed liquid inside quickly passes through the filter hopper 908 under high-speed rotation and enters the interior of the liquid storage bucket 919, and the filtered organic solution containing lutein is discharged through the liquid outlet pipe 917.

[0034] When there is a large amount of residue accumulated inside the filter hopper 908, the motor two 903 drives the lead screw 904 to rotate, and drives the connecting block 906 to move upward along the reinforcing rod 905. (The reinforcing rod 905 can keep the connecting block 906 in a horizontal state to extend the service life of the lead screw 904), thereby driving the motor three 907 to move upward, and driving the fixing plate 912 to move upward under the action of the connecting foot 909, thereby driving the filter hopper 908 to move upward, so that the filter hopper 908 moves outside the liquid storage barrel 919. Then, the filter hopper 908 can be removed by rotating the mounting bolt 913 to clean the residue inside the filter hopper 908. When the residue cleaning is completed, the filter hopper 908 is installed through the mounting bolt 913, and then the filter hopper 908 is lowered into the liquid storage barrel 919 by reversing the motor two 903. Before the filter hopper 908 enters the liquid storage barrel 919, it is necessary to rotate the rotating frame 910 so that the limiting blocks 911 on both sides coincide with the limiting grooves 918 on both sides inside the liquid storage barrel 919. When the filter hopper 908 enters the liquid storage barrel 919, the limiting rod 914 will insert into the rotating hole 916 inside the support plate 915, and the support plate 915 can play a supporting role for the filter hopper 908.

[0035] Working principle: When using this device, first, simultaneously inject organic solvents into the inside of the stirring barrel 1 through the liquid inlet 3, and inject plant raw materials into the inside of the stirring barrel 1 through the feeding port 4, so that the organic solvents and plant raw materials are mixed when injected into the inside of the stirring barrel 1, reducing the later stirring and mixing time. During this process, the water stop valve 7 should be in a closed state. After the injection of the organic solvents and plant raw materials is completed, drive the square rod 502 to rotate inside the fixed tube 503 by the first motor 501. When the square rod 502 rotates, it will drive the stirring rod 506 to rotate through the set square hole 507. When the stirring rod 506 rotates, it will drive the stirring blade 512 to rotate, and will also drive the second extrusion block 505 to rotate. When the second extrusion block 505 rotates, under the action of the first extrusion block 504, the second extrusion block 505 will move downward, thereby driving the stirring rod 506 to move downward, and under the action of the extrusion plate 508, it will squeeze the connecting plate 509 downward and squeeze the spring 511. When the mutually approaching surfaces of the first extrusion block 504 and the second extrusion block 505 coincide, under the action of the spring 511, it will squeeze the connecting plate 509 to move upward and push the upper extrusion plate 508 to move upward, thereby driving the stirring rod 506 to move upward, and then driving the stirring blade 512 to move upward, realizing the simultaneous up and down movement while the stirring blade 512 is stirring, greatly shortening the mixing time of the plant raw materials and the organic solvents, enabling lutein to quickly dissolve into the organic solvents. When the plant materials and the organic solvents are fully mixed, open the water stop valve 7. At this time, the fully mixed liquid will sequentially pass through the first drain pipe 6, the water stop valve 7, and the second drain pipe 8 and enter above the filter hopper 908 inside the storage barrel 919. Then drive the lower connecting foot 909 to rotate by the third motor 907, thereby driving the fixed plate 912 to rotate. When the fixed plate 912 rotates, it will drive the filter hopper 908 to rotate inside the rotating frame 910. When the filter hopper 908 rotates, the mixed liquid inside will quickly pass through the filter hopper 908 under high-speed rotation and enter the inside of the storage barrel 919, and the filtered organic solution containing lutein will be discharged through the liquid outlet pipe 917. When there is a lot of residue accumulated inside the filter hopper 908, drive the lead screw 904 to rotate by the second motor 903, and drive the connecting block 906 to move upward along the reinforcing rod 905 (the service life of the lead screw 904 can be extended by making the connecting block 906 in a horizontal state through the reinforcing rod 905), thereby driving the third motor 907 to move upward, and under the action of the connecting foot 909, driving the fixed plate 912 to move upward, and then driving the filter hopper 908 to move upward, so that the filter hopper 908 moves outside the storage barrel 919. Then, remove the filter hopper 908 by rotating the mounting bolt 913 to clean the residue inside the filter hopper 908. After the residue is cleaned, install the filter hopper 908 through the mounting bolt 913, and then reverse the second motor 903 to lower the filter hopper 908 into the inside of the storage barrel 919.Before the filter hopper 908 enters the interior of the liquid storage barrel 919, it is necessary to rotate the rotating frame 910 so that the limiting blocks 911 on both sides coincide with the limiting grooves 918 on both sides inside the liquid storage barrel 919. When the filter hopper 908 enters the interior of the liquid storage barrel 919, the limiting rod 914 will insert into the rotating hole 916 inside the support plate 915, and the support plate 915 can play a supporting role for the filter hopper 908.,
