[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0019] See also Figure 1-Figure 2 A typical embodiment of the present application provides a fermentation warehouse for making wine koji, including a fermentation warehouse body 1, a plurality of movable mechanisms arranged on the side wall of the fermentation warehouse body 1, and an exhaust fan 2. Specifically, the fermentation warehouse body 1 is composed of a wall, a herringbone tile roof cover, and a red brick floor. The walls on the left and right sides of the fermentation warehouse body 1 are respectively provided with inlet and outlet doors and three sets of exhaust windows, and the three sets of exhaust windows are arranged in parallel. Bamboo mats parallel to the two inclined surfaces of the herringbone are respectively arranged under the tile roof cover, and straw is laid between the bamboo mat and the tile roof cover.
[0020] The movable mechanism is installed inside the exhaust window. There are three groups of movable mechanisms. The exhaust fan 2 is installed on each movable mechanism. The height of the exhaust fan 2 is adjusted by the movable mechanism. A rectangular frame is arranged outside the exhaust fan. The exhaust fan is an industrial fan.
[0021] Specifically, the movable mechanism includes a retractable baffle 3, a movable track 4, a pulley 5 adapted to the movable track 4, and a driving motor 6. The movable track 4 is vertically arranged on both inner sides of the exhaust window of the fermentation bin body 1. The baffle 3 is connected between the exhaust fan 2 and the movable track 4. One end of the pulley 5 is connected to two opposite sides of the frame of the exhaust fan 2 through a connecting rod and an axle seat. Four groups of pulleys 5 are arranged, which are respectively arranged at the four corners of the frame of the exhaust fan 2 and are symmetrically arranged.
[0022] The driving motor 6 is arranged at the uppermost end of the moving track 4. The driving motor 6 is a straight rod motor. The left and right output ends of the driving motor 6 are connected to the exhaust fan 2 through a chain. In order to ensure the stability of movement, a straight rod is arranged on the top of the frame of the exhaust fan 2. The two ends of the straight rod are respectively arranged corresponding to the output ends of the driving motor 6. The chains at the two ends of the driving motor 6 are correspondingly connected to the two ends of the straight rod of the exhaust fan 2. When the exhaust fan 2 moves up and down, it can maintain good stability.

The controller can control the up and down movement of multiple groups of exhaust fans 2 at the same frequency, and exhaust can be performed at different heights in the fermentation bin, so as to adjust the temperature and humidity inside the fermentation bin, which is beneficial to the fermentation of koji. In other embodiments, the controller can be adjusted so that the exhaust fan moves up and down at a uniform speed to achieve effective exhaust and keep the inside of the bin dry.
[0025] On the whole, the exhaust fan 2 configured inside the fermentation bin body 1 can be moved up and down through a movable mechanism. The height of the exhaust fan 2 can be adjusted according to the temperature and humidity inside the fermentation bin body 1, so that the upper space of the fermentation bin body 1 can be exhausted and the temperature and humidity inside the fermentation bin body 1 can be reasonably adjusted. Exhaust can be performed at positions of different heights in the fermentation bin to adjust the temperature and humidity inside the fermentation bin. During the front fermentation, excess moisture in the bin can be quickly discharged, and the koji blocks can be quickly dried during the post-fermentation, which is beneficial to the quality of the Daqu.
