Description

Technical Field

[0001] The utility model relates to a stirring device, in particular to a mixing and stirring device for plant yeast raw materials, belonging to the technical field of yeast preparation. Background Art

[0002] In the process of making plant koji, people mainly use common plants such as Polygonum hydropiper, Verbena, and Bamboo Leaf. These plants are not only easy to obtain, but also rich in nutrients suitable for the growth of microorganisms. These plants are crushed and mixed according to traditional methods, and fermented under certain conditions to form active koji. In the process of making plant koji, the above plants need to be dried and ground into powder, mixed with koji mother and rice powder in a certain proportion, and then water is added to fully stir until it can be rolled into a ball, and then rolled into a ball for standby use. Mixing and stirring the raw materials is a crucial link. It is necessary to ensure that the koji is uniform, without dry powder and lumps. The traditional stirring method often relies on manual operation, which is inefficient and difficult to ensure mixing uniformity, thus affecting the quality of the koji.

[0003] For example, a "drinking yeast stirring device" disclosed in Chinese patent documents, with the announcement number CN218774692U, includes a bottom plate, a starting motor drives the disc 1 to rotate, and then drives the disc 2 to rotate through a belt, and the rotation of the disc 1 drives the connecting shaft and the short rod 1 to rotate, and then drives the end of the rotating rod away from the short rod 1 to move up and down, and then pushes the end of the long rod away from the rotating rod to move up and down, and then the short rod 2 is slightly rotated near the end of the long rod, and then the stirring rod is pulled up and down, and then the raw materials in the mixing barrel can be stirred. This stirring device can achieve stirring while the mixing barrel rotates and the stirring rod is used to mix the raw materials more evenly.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that the above equipment still has the following defects: 1. The mixed raw materials during the stirring process may adhere to the inner wall and bottom wall of the stirring equipment. On the one hand, the adhered raw materials do not participate in the stirring and mixing, which will cause waste of raw materials. On the other hand, these adhered raw materials are very likely to be in the state of dry powder and lumps. In the later discharging process, this part of the adhered raw materials may be discharged together with the evenly mixed raw materials, affecting the quality of the finished koji; 2. The container of the stirring equipment is generally a vertical cylindrical structure with an open upper end. When the raw materials are stirred and mixed into a mass, the deeper cylinder is not conducive to the removal of the finished product, and the stirring equipment is also inconvenient to clean.

[0005] Therefore, a plant koji raw material mixing and stirring device was designed. Utility Model Content
