[0002] The Daqu for Maotai-flavor liquor 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 Daqu for Maotai-flavor liquor mainly includes: wheat moistening, wheat crushing, addition of mother koji, water addition and mixing, koji cake forming, koji airing, koji stacking and culturing in the house, koji turning, koji removing and storage, etc. From wheat moistening to koji cake forming, mechanization or automation has been basically realized, while the stacking and culturing of Daqu for Maotai-flavor liquor still uses the traditional manual koji placing and stacking method, which requires a large amount of rice straw, resulting in that operations such as koji placing, koji turning and koji removing can only be realized manually. During the traditional koji cake stacking and culturing process, the culturing temperatures, moisture contents, etc. of the upper, middle, lower, outer and inner koji cakes are inconsistent. After culturing for a certain period of time, manual koji turning is required, turning the upper part to the lower part and the inner part to the outer part to ensure that the culturing states of each layer of koji cakes are consistent and uniform. Manual koji turning has a large labor intensity, low production efficiency, and the temperature and humidity in the culturing house are high, and the dust is large, the working environment is harsh. At the same time, a large amount of waste rice straw is generated, which limits the high-efficiency, mechanized and automated production of Daqu for Maotai-flavor liquor.

If this specific posture changes, then the directional indication also changes accordingly. If there are terms related to quantity involved in the present utility model, such as "many", "multiple", "several", etc., it specifically refers to two or more.

[0022] As Figure 1 、 Figure 2 and Figure 3 As shown in

[0023] The cylindrical Jiangxiang Daqu stacking and culturing device of the present utility model includes a support frame 1, side plates 2, a top plate 3, a bottom plate 4, a door panel, and multiple porous cylindrical koji baskets 6. The side plates 2 are arranged on the left and right sides of the support frame 1, the door panel is arranged on the front and back sides of the support frame 1 in an openable manner, the top plate 3 is arranged on the upper part of the support frame 1, the bottom plate 4 is arranged on the lower part of the support frame 1. The side plates 2, the top plate 3, the bottom plate 4, and the door panel enclose a receiving cavity. The porous cylindrical koji basket 6 is in a hollow cylindrical shape, and multiple ventilation holes are arranged on the porous cylindrical koji basket 6. All the porous cylindrical koji baskets 6 are connected together in sequence, and all the porous cylindrical koji baskets 6 are arranged in the receiving cavity;

[0023] Support legs 5 are connected and arranged at the upper and lower ends of the support frame 1. The side plates 2, the top plate 3, the bottom plate 4, and the door panel are all porous and hollow structures.

[0024] The koji bricks are installed in the porous cylindrical koji baskets 6 for stacking and culturing. The shape of the koji bricks is also cylindrical. Through a large number of practices and tests, it is found that when the cylindrical koji bricks are installed in the porous cylindrical koji baskets 6, the uniformity of koji brick culturing can be improved, and the Jiangxiang flavor can be enhanced.

[0025] The side plates 2, the top plate 3, the bottom plate 4, and the door panel are all porous and hollow structures, and multiple ventilation holes are arranged on the porous cylindrical koji basket 6, which can facilitate oxygen ventilation and waste discharge, and realize the gas circulation and exchange during the process of koji brick stacking and culturing. According to the space of the culturing room and the requirements of heat preservation, moisture preservation in the early stage of culturing and moisture discharge in the later stage. Since the permeability of this stacking and culturing device is relatively good, as long as the ventilation and moisture discharge effects are ensured, even without turning the koji, a relatively good-cultured Daqu can be obtained. At the same time, this stacking and culturing device can also cooperate with the koji turning equipment for koji turning operations. For example, the koji frame can be grasped by a robotic arm and flipped by 180°, and the support legs 5 at the upper and lower ends of the support frame 1 are used for support, so that the up and down positions can be swapped, avoiding the problem of different culturing degrees of koji bricks caused by uneven temperature and humidity in the culturing room space.

[0026] For the specific structure of the stacking culture device, the present utility model provides the following preferred solutions:

[0027] To ensure the stability of the overall structure of the stacking culture device and not affect the koji block culture, it is preferably that the support frame 1, side plates 2, top plate 3, bottom plate 4, door panels and porous cylindrical koji baskets 6 are all made of stainless steel material, such as 304 stainless steel.

[0028] For convenient stacking, the support frame 1 can adopt a cuboid frame structure, and the frame uses multiple upright columns 11 arranged at intervals around the top plate 3. Specifically, four upright columns 11 can be used, and the four upright columns 11 are located on the four prisms of the cuboid frame.

[0029] After the support frame 1 is installed, the side plates 2 can be installed. The side plates 2 adopt mesh plates and are directly welded to the left and right side surfaces of the support frame 1.

[0030] For the door panels, to ensure the stability of the connection, it is preferably to set one door panel on each of the front and rear sides of the support frame 1. The door panels are also made of mesh plates. The door panels are connected to the upright columns 11 through hinges on the left or right side. Of course, a lock structure needs to be set on the side of the door panel far from the hinge to ensure the stable connection between the door panel and the support frame 1 in the closed state.

[0031] For convenient processing, the structures of the top plate 3 and the bottom plate 4 are the same. The specific structure of the bottom plate 4 is as Figure 4 shown, including an outer frame 41 and multiple support rods 42 arranged vertically and horizontally inside the outer frame 41, and a mesh plate 43 laid on the outer frame 41 and the support rods 42. The specific number of the support rods 42 is reasonably set according to the size of the partition plate 4, and it can ensure that the mesh plate 43 can bear the weight of the koji block without deformation.

[0032] In addition, to prevent the koji block from falling from the through holes of the mesh plate 43 and at the same time meet the temperature and humidity required for koji block culture, heat preservation and humidity preservation layers are provided on the inner side surfaces of the side plates 2 and the door panels, as well as on the inner side surfaces of the top plate 3 and the bottom plate 4. The heat preservation and humidity preservation layers can be curtain layers made of straw curtains or fiber materials. Specifically, they can be fixed by tying or pasting to prevent falling off during the koji turning process.

[0033] To improve the utilization rate of the accommodation cavity, all the porous cylindrical koji baskets 6 are arranged in an array in the accommodation cavity. To improve the connection stability of the porous cylindrical koji baskets 6, the porous cylindrical koji baskets 6 are welded to the side plates 2, top plate 3 and bottom plate 4 together.
