[0056] When extracting lily polysaccharides, the cover plate 10 is against the extraction tank body 15, and hot water and lily are added into the extraction tank body 15 through the water adding pipe 13 and the feeding pipe 11 respectively. The stepping motor 30 drives the rotating shaft 7 to rotate, and then drives the plurality of stirring blades 9 to rotate. During the rotation of the stirring blades 9, the lily and hot water in the extraction tank body 15 can be stirred and mixed, thereby improving the extraction effect of lily polysaccharides.

[0057] After the lily polysaccharide extraction is completed, the servo motor 32 drives the single-thread screw 34 to rotate, and then drives the lifting bracket 31 to slide upward. Driven by the lifting bracket 31, the cover plate 10, the rotating shaft 7 and the filter plate 4 move upward. During the upward sliding of the filter plate 4, the extract passes through the filter hole 3 through the filter plate 4, and the lily waste is retained on the surface of the filter plate 4.

[0058] After the extraction liquid is collected, the stepper motor 30 drives the rotating shaft 7 to rotate, and then drives the stirring blade 9 and the scraper 5 to rotate. During the rotation of the scraper 5, the lily waste on the surface of the filter plate 4 is cleaned, and the water valve is opened. The cleaning water enters into the fixed pipes 19 through the water pipe 12 and is sprayed out by the flushing nozzles 17. The flushing nozzles 17 spray the cleaning water downward to flush the stirring blade 9, the scraper 5 and the filter plate 4. The cleaned lily waste enters the collecting tube 23, and the solid waste gathers at the top of the hollow circular plate 25. During the flushing process, part of the sewage flows to the collecting tube 23 through the drainage hole 24 on the hollow circular plate 25. The bottom of the hollow circular plate 25 is connected to the bottom of the hollow circular plate 25 and is discharged from the drain pipe 21. The remaining sewage flows into the extraction tank body 15 through the filter holes 3 on the filter plate 4 and is discharged from the discharge pipe 2. The pull-out plate 28 is pulled outward, the waste discharge trough 27 is opened, and the staff pushes the cleaning plate 22 to rotate. During the rotation of the cleaning plate 22, the solid waste on the top of the hollow circular plate 25 is pushed to move. When passing through the waste discharge trough 27, the solid waste enters the waste discharge pipe 29 through the waste discharge trough 27 and is discharged to the outside for collection by the waste discharge pipe 29, thereby realizing the function of quickly cleaning and collecting the separated lily waste.
