Description

Technical Field

[0001] The utility model relates to the technical field of soy sauce koji turning devices, in particular to a soy sauce koji turning device. Background Art

[0002] In the process of soy sauce production, koji making is one of the key links. Koji making uses koji to capture rich microorganisms in the air and nature, allowing molds for saccharification, yeasts for fermentation, and bacteria for aroma production to grow and reproduce, producing enzymes necessary for brewing. When making koji, traditional koji making methods rely on manual turning of the koji. Manual turning of the koji is not only labor-intensive and inefficient, but also difficult to ensure uniform fermentation and ventilation of the koji, thus affecting the quality and yield of the soy sauce. At present, in order to reduce the workload of the staff and to ensure that the koji is turned more evenly, corresponding koji turning devices are usually used. There are many types of koji turning devices on the market, and most of them use motors to drive the corresponding stirring blades to rotate to achieve the turning operation.

[0003] However, when such a koji turning device is turning the koji, the corresponding blades can only turn the koji material in the horizontal direction, and there is a defect that the koji material at the bottom layer cannot be turned upward, which will cause the koji material at the bottom layer to always be at the bottom, making it difficult to ensure the ventilation effect of the koji material at the bottom layer, affecting the preparation effect and bringing inconvenience to the user. In view of this, we propose a koji turning device for soy sauce koji making. Utility Model Content
