The method for using the extraction and purification device for liver-protecting blue lonicera caerulea polysaccharide according to claim 6, characterized in that: The following steps are involved: The collected blue indigo fruit is fed into the top of the box (1), and the surface of the blue indigo fruit is cleaned and dried; The blue indigo fruit after cleaning and surface drying enters the crushing and cleaning mechanism (5) for crushing treatment. The blue indigo fruit is located on the extrusion filter plate (5-2). The rotating extrusion cleaning arm (5-1) arranged on the extrusion filter plate (5-2) is rotated to squeeze and crush the blue indigo fruit. During the rotation and extrusion process, the pomace on the extrusion filter plate (5-2) is cleaned. When the flipping and blocking component blocks the through groove of the extrusion filter plate (5-2), the juice flows out through the holes on the extrusion filter plate (5-2) and enters the extraction mechanism (7). When the flipping and blocking component is flipped and the through groove is not blocked, the rotating extrusion cleaning arm (5-1) is rotated to send the pomace out of the through groove, and the pulp of the blue indigo fruit after the extrusion and crushing treatment is separated from the liquid. The separation of the pomace and the juice is achieved in the continuous operation, and then the blue indigo fruit polysaccharide is respectively sent to the extraction mechanism for extraction. The extracted clear liquid containing blue loquat polysaccharide is introduced into the replacement inner tank of the purification mechanism (9), and the freezing component is started to perform freeze drying to obtain purified blue loquat polysaccharide; Regularly replace the replacement liner for freeze-dried blue loquat polysaccharide to ensure continuous operation.
