The structure is a relatively common and general fermentation tank, but when used for extracting candida utilis protein from corn syrup, the corn syrup liquid is viscous, and due to slow stirring during fermentation, including temperature transmission, some additives and the like in the later stage, the stirring cannot be uniform and fast; and the material is easily adhered to the tank wall, stirring teeth and the like, which is not convenient to clean.

[0004] Application No. 2023223090948 discloses an agricultural biological protein selenium nutrient liquid fermentation tank, comprising a cover body and an outer shell, the cover body and the outer shell are fixedly connected through bolts, the inner side of the first circular plate and the second circular plate is attached with two arc-shaped plates movably connected with the outer wall of the stirring rod, the outer side of the two arc-shaped plates is fixedly connected with a scraper plate attached with the inner wall of the outer shell, the inner side groove of the arc-shaped plate is movably connected with a protrusion, one side of the protrusion is fixedly connected with the outer side of the stirring rod, and the outer side of the two arc-shaped plates is movably connected with a limiting cylinder. The utility model relates to the technical field of protein selenium nutrient liquid production equipment, and through the cooperation between the stirring rod, the baffle and the limiting cylinder, the original liquid is fully mixed and scraped off from the inner wall, the original liquid is uniformly heated, the problem that the original liquid is not uniform when heated is solved, the fermentation time of the original liquid is prolonged, and the working efficiency is reduced.

[0005] The above scheme is provided with an inner wall scraper plate, which can effectively clean the inner wall, but there are still many residues on the stirring shaft and stirring teeth, which are still inconvenient to clean. UTILITY MODEL CONTENTS
