[0002] Edible fungi are large fungi that are edible to humans. Common ones include shiitake mushrooms, oyster mushrooms, enoki mushrooms, Agaricus blazei and black fungus. They are delicious, high in protein, low in sugar, low in fat and low in cholesterol. They are rich in nutrients, rich in high-quality protein, carbohydrates, multiple vitamins, mineral elements and other ingredients. Edible fungus polysaccharides are metabolites separated from fungal fruiting bodies, mycelium and their fermentation broth. Edible fungus polysaccharides have a wide range of effects, and have certain effects in anti-cancer, antibacterial, lowering blood sugar, lowering blood lipids, protecting the liver, anti-aging and immune regulation.

4. A method for using an edible fungus polysaccharide extraction and separation device, characterized in that: The edible fungus polysaccharide extraction and separation device according to claim 3 comprises the following steps: S1: When in use, an operator adds diced mushrooms and deionized water into the interior of the mixing barrel (3) from the feed port, then covers the upper cover plate (4) to seal the interior of the mixing barrel (3), and drives the first pulley (14) to rotate by means of the dual-axis drive motor (13) in forward rotation. The first pulley (14) drives the second pulley (16) to rotate via the belt (15), so that the second pulley (16) drives the rotating shaft (17) to rotate, and the rotating shaft (17) drives the two partitions (18) to rotate. The two partitions (18) drive the roller (21) to move around the rotating shaft (17). S2: The roller (21) drives the gear (29) to move, and the gear (29) drives the roller (21) to rotate by meshing with the annular gear (28), so that the roller (21) rotates while moving. When the opening on the outer surface of the roller (21) leaves the sealing plate (22), the mixture of diced mushrooms and deionized water enters the mixing chamber of the roller (21); S3: The square slide bar (30) is driven to move by the partition (18), and the square slide bar (30) is driven to reciprocate by the guide column (31) and the contoured groove (20). The square slide bar (30) drives the pistons (32) to move away from or towards each other. When the pistons (32) move away from each other, the air pressure inside the mixing chamber is negative, and the air inside the diced mushrooms is released. When the pistons (32) move towards each other, the air pressure inside the mixing chamber returns to normal. At this time, the diced mushrooms will absorb a large amount of deionized water into the tissue to restore the normal shape. Through multiple reciprocating movements, the tissue inside the diced mushrooms is fully infiltrated by the deionized water, and the deionized water dissolves the polysaccharides inside the tissue. S4: The reciprocating motion of the square slide bar (30) drives the connecting rod (27) to reciprocate, so that the connecting rod (27) drives the slide plate (26) to reciprocate along the slide groove (25), and the slide plate (26) drives the second shear plate (24) and the first shear plate (23) to shear each other. Through this device, the diced mushrooms in the mixture can be sheared into smaller pieces, which is convenient for deionizing the polysaccharides inside the mushrooms; S5: The transmission shaft (10) is driven to rotate by the reverse rotation of the dual-axis driving motor (13), and the transmission shaft (10) drives the driving plate (11) to move eccentrically. The driving plate (11) drives the filter plate (9) to move up and down through the connecting rod (12), so as to screen and filter the mixed liquid of mushroom scraps and deionized water that falls on the surface of the filter plate. The filtered mixed liquid of deionized water flows into the collection box through the liquid outlet pipe (8).
