[0001] The utility model relates to the technical field of brewing, in particular to a koji frame for mechanized fermentation of high-temperature Daqu. Background Art

[0002] High-temperature Daqu provides the bacterial system, enzyme system and material system required for the production of Maotai-flavor liquor, and makes an important contribution to the style and quality of Maotai-flavor liquor. The production process of high-temperature Daqu mainly includes: material moistening, crushing, adding mother koji, adding water for mixing, koji block forming, koji airing, stacking fermentation in the workshop, koji turning, cultivation management and koji dismantling and storage, etc. From material moistening to koji block forming, mechanization has been basically realized. The koji stacking of high-temperature Daqu still uses the traditional stacking method and requires a large amount of straw, resulting in that processes such as koji stacking, koji turning and koji dismantling can only be realized through manual operation. During the stacking fermentation process of koji blocks, the fermentation temperatures, moisture contents, etc. of the upper, middle, lower, outer and inner koji blocks are inconsistent. After fermenting for a certain period of time, manual koji turning is required, turning the upper layer to the lower layer and the inner layer to the outer layer to ensure that the fermentation states of each layer of koji blocks are consistent and uniform. Manual koji turning has a large labor intensity, low production efficiency, and the temperature, humidity and dust in the fermentation workshop are high, and the working environment is harsh, which restricts the high-efficiency, mechanized and automated production of high-temperature Daqu. Content of the Utility Model

[0018] It should be noted that if there are directional indication terms in the present utility model, such as the directions and azimuth terms of up, down, left, right, front and back, they are for the convenience of describing the relative position relationship between components. They are not the absolute position specific references for the relevant components and the position relationship between components. They are only used to explain the relative position relationship and movement conditions between components in a certain specific posture. If this specific posture changes, then this directional indication will also change accordingly. If there are quantity terms in the present utility model, such as "many", "multiple", "several", etc., specifically refer to two or more.

[0019] Such as Figure 1 、 Figure 2As shown in the figure, the koji frame for mechanized fermentation of high-temperature Daqu of the present utility model includes at least one koji frame body, and the koji frame body includes a support frame 1 and a bottom plate 2. The support frame 1 is a hollow structure with an open upper end. The bottom plate 2 is arranged on the inner bottom surface of the support frame 1.
