[0002] In the market, there are various forms of Polygonatum health food, including capsules, tablets, oral liquids, granules, etc. When producing Polygonatum health food, it is necessary to first add the Polygonatum raw material to the corresponding auxiliary materials for mixing and stirring.

[0003] After searching, the Chinese patent with publication number CN219663415U discloses a Huangjing food processing and mixing device, including a base, including a fixed platform; a mixing mechanism, which is arranged on the base, including a storage component arranged on the fixed platform and a mixing component arranged in the storage component, the storage component includes a mixing barrel arranged on the fixed platform and a feeding pipeline arranged on the mixing barrel, the mixing component includes a mixing shaft arranged in the mixing barrel and a plurality of mixing rods installed outside the mixing shaft; a collecting mechanism, which is arranged on the base, includes a collecting box arranged on the fixed platform. The patent adds Huangjing and other auxiliary materials to the mixing barrel through the feeding pipeline, uses a mixing motor to drive the mixing shaft to rotate, and the mixing rod on the mixing shaft continuously stirs and mixes the Huangjing and the auxiliary materials, and the scraper can hang down the auxiliary materials adhering to the mixing barrel to increase the utilization rate of the auxiliary materials.

When the piston rod 132 moves toward the hopper 11, the air at one end of the bottom tube 12 is blown out through the one-way valve 122, and the small particle ingredients dropped from the hopper 11 in the bottom tube 12 are blown into the mixing tank 3 through the end bucket 121. The feeding process continues with the stirring operation to avoid the concentrated addition of small particle ingredients affecting the stirring effect; when the piston rod 132 moves away from the hopper 11, air is evacuated through the one-way valve 123.

When the piston rod 132 moves toward the hopper 11, the air at one end of the bottom tube 12 is blown out through the one-way valve 122, and the small particle ingredients dropped from the hopper 11 in the bottom tube 12 are blown into the mixing tank 3 through the end bucket 121. The feeding process continues with the stirring operation to avoid the concentrated addition of small particle ingredients affecting the stirring effect. When the piston rod 132 moves away from the hopper 11, air is evacuated through the one-way valve 123.
