Description

Technical Field

[0001] The utility model relates to the technical field of wine making, in particular to a cylindrical sauce-flavored Daqu stacking fermentation device. Background Art

[0002] Maotai Daqu provides the bacterial, enzyme and material systems required for the production of Maotai-flavor liquor, and has an important contribution to the style and quality of Maotai-flavor liquor. The production process of Maotai Daqu mainly includes: wheat tempering, wheat crushing, mother koji addition, water mixing, koji blank forming, koji drying, koji placement in the room for pile fermentation, koji turning, koji removal and storage. From wheat tempering to koji blank forming, mechanization or automation has been basically achieved, while the Maotai Daqu pile fermentation still uses the traditional manual koji placement and stacking method, which requires the use of a large amount of straw, resulting in the need for manual operation to achieve the processes of koji placement, koji turning and koji removal. In the traditional koji pile fermentation process, the fermentation temperature and moisture content of the koji blanks in the upper, middle and lower layers, as well as the outer and inner layers are inconsistent. After a certain period of fermentation, the koji needs to be turned manually, up and down, inside and outside, to ensure that the fermentation state of each layer of koji blanks is consistent and uniform. Manual turning over of the fermented koji is labor-intensive and has low production efficiency. In addition, the temperature and humidity in the fermentation room are high, the dust is high, and the working environment is poor. At the same time, a large amount of waste straw is produced, which limits the high-efficiency, mechanized and automated production of Maotai-flavor Daqu. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings of the existing stacking fermentation method, the technical problem to be solved by the utility model is to provide a cylindrical Maotai-flavor Daqu stacking fermentation device which is conducive to mechanized turning over of the koji.

[0004] The utility model solves the technical problem by adopting the following technical solution: a cylindrical sauce-flavored Daqu stacking fermentation device, comprising a supporting frame, side panels, a door panel, a partition and a porous cylindrical Qu basket, wherein the side panels are arranged on the left and right sides of the supporting frame, the door panel can be opened and arranged on the front and rear sides of the supporting frame, the partition comprises a plurality of pieces and is arranged in the supporting frame at intervals along the vertical direction, and each partition is provided with a plurality of parallel porous cylindrical Qu baskets;

[0005] The upper and lower ends of the support frame are connected with supporting legs, and the side panels, door panels and partitions are all porous hollow structures.

[0006] Furthermore, the supporting frame includes a plurality of columns spaced around the partition.

[0007] Furthermore, a door panel made of a mesh plate is provided on each of the front and rear sides of the support frame, and the door panel is connected to the column through a hinge on the left or right side.

[0008] Furthermore, the partition includes an outer frame and a plurality of support rods crisscrossedly arranged in the outer frame, and a mesh plate laid on the outer frame and the support rods.

[0009] Furthermore, heat-insulating and moisture-preserving layers are provided on the inner sides of the side plates and the door plate, as well as on the upper and lower surfaces of the partition board.

[0010] Furthermore, the support frame, the side plates, the door plate and the partition board are all made of stainless steel.

[0011] Furthermore, the heat-insulating and moisture-preserving layer is a straw curtain or a fiber curtain.

[0012] Furthermore, the porous cylindrical koji baskets are arranged on the partition board by welding.

[0013] Furthermore, reinforcing ribs are connected around the porous cylindrical koji baskets, and the reinforcing ribs are connected to the support frame or the side plates.

[0014] The beneficial effects of the present utility model are as follows: multiple partition boards are arranged at intervals to set the porous cylindrical koji baskets, and the koji blanks are installed in the porous cylindrical koji baskets for stacking and culturing fermentation, which can improve the space utilization rate of the fermentation room. At the same time, the side plates, the door plate and the partition board with porous hollow structures are beneficial to air flow, which helps to keep warm and moisturize in the early stage of stacking fermentation and discharge moisture in the later stage. Even without turning the koji, the production of soy sauce-flavored Daqu can be realized; an automated transfer robot can also be used to transfer the stacking fermentation device to the fermentation room for dense stacking or turn the koji frame by 180° to realize the koji turning operation, which can significantly reduce the labor intensity of workers and is beneficial to the mechanization, automation, scale and standardization of soy sauce-flavored Daqu production.

[0020] The present utility model will be further described below with reference to the accompanying drawings.

[0021] It should be noted that if there are directional indication terms in the present invention, such as up, down, left, right, front, and back directions and orientation terms, they are for the purpose of facilitating the description of the relative position relationship between components, and are not for the absolute position of the related components or the position relationship between components. They are only used to explain the relative position relationship and movement of the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly. If there are terms related to quantity in the present invention, such as "multiple", "multiple", "several", etc., they specifically refer to two or more.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the cylindrical Maotai-flavor Daqu stacking fermentation device of the utility model comprises a support frame 1, a side panel 2, a door panel, a partition 4 and a porous cylindrical Qu basket 6, the side panel 2 is arranged on the left and right sides of the support frame 1, the door panel can be opened and arranged on the front and rear sides of the support frame 1, the partition 4 includes a plurality of pieces and is arranged in the support frame 1 at intervals along the vertical direction, and each partition 4 is provided with a plurality of side-by-side porous cylindrical Qu baskets 6;

[0023] The upper and lower ends of the support frame 1 are connected with supporting legs 5, and the side panels 2, door panels and partition panels 4 are all porous hollow structures.

[0024] Two adjacent partitions 4, the side panels 2 and the door panels enclose a accommodating cavity, in which a porous cylindrical koji basket 6 is arranged. The porous cylindrical koji basket 6 is cylindrical in shape, and air holes are arranged on the surface of the cylinder. The koji blanks are installed in the porous cylindrical koji basket for stacking and fermenting. The shape of the koji blanks is also cylindrical. Through a lot of practice and experiments, it is found that the cylindrical koji blanks are installed in the porous cylindrical koji basket 6, which can improve the uniformity of the koji fermentation and improve the sauce flavor.

[0025] Since the koji billets produced by automated production are generally pressed and formed by special equipment, the size of the partition 4 and the spacing between adjacent partitions 4 can be designed according to the size of the koji billets. The koji billets should be smaller than the volume of the accommodating cavity to ensure that a certain ventilation space can be reserved between each layer of koji billets. The side panels 2, door panels and partitions 4 are all porous hollow structures, which can facilitate oxygenation and waste discharge, and realize gas circulation and exchange during the koji billet stacking and bacterial fermentation process. According to the space of the fermentation room and the requirements of heat preservation and moisture retention in the early stage of fermentation and moisture removal in the later stage, while taking into account the space utilization rate, six layers of partitions 4 can be set on a stacking fermentation device. Since the stacking fermentation device has good permeability, as long as the ventilation and moisture removal effect is ensured, even if the koji is not turned over, a large koji with a good fermentation degree can be obtained. At the same time, the stacking fermentation device can also cooperate with the koji turning device to turn over the koji, such as grasping the koji frame by a mechanical arm to turn it 180°, and using the legs 5 at the upper and lower ends of the support frame 1 for support, so that the upper and lower positions can be exchanged, avoiding the problem of different fermentation degrees of the koji billets due to uneven temperature and humidity in the fermentation room space.

[0026] Regarding the specific structure of the stacking fermentation device, the utility model provides the following preferred solutions:

[0027] In order to ensure the stability of the overall structure of the stacking fermentation device and not affect the fermentation of the koji, the support frame 1, side panels 2, door panels and partitions 4 are preferably made of stainless steel, such as 304 stainless steel.

[0028] In order to facilitate stacking, the support frame 1 can adopt a rectangular parallelepiped frame structure, and the frame adopts a plurality of columns 11 arranged at intervals around the partition 4. Specifically, four columns 11 can be adopted, and the four columns 11 are located on the four prisms of the rectangular parallelepiped frame.

[0029] After the partition 4 is installed, the side panels 2 can be installed. The side panels 2 are made of mesh panels and are directly laid on the left and right sides of the supporting frame 1.

[0030] For the door panel, in order to ensure the stability of the connection, it is best to set a door panel on each of the front and rear sides of the support frame 1. The door panel is also made of a mesh plate, and the door panel is connected to the column 11 through a hinge on the left or right side. Of course, a lock structure needs to be set on the side of the door panel away from the hinge to ensure the stable connection between the door panel and the support frame 1 in the closed state.

[0031] The specific structure of the partition 4 is as follows Figure 4 As shown, it includes an outer frame 41 and a plurality of support rods 42 crisscrossedly arranged in 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 4, and it can ensure that the mesh plate 43 can bear the weight of the billet without deformation.

[0032] In addition, in order to prevent the koji blank from falling off through the through holes of the mesh plate 43 and to meet the temperature and humidity requirements for koji blank fermentation, heat and moisture insulation layers are provided on the inner sides of the side plates 2 and the door plate, as well as on the upper and lower surfaces of the partition plate 4. The heat and moisture insulation layers can be curtain layers made of straw curtains or fiber materials. Specifically, they can be fixed to the side plates 2, the door plate, and the partition plate 4 by tying or pasting to prevent them from falling off during the koji turning process.

[0033] To improve the connection stability of the porous cylindrical koji baskets 6, the porous cylindrical koji baskets 6 are arranged on the partition plate 4 by welding, and all the porous cylindrical koji baskets 6 are arranged in an array. Further, as shown in Figure 1 、 Figure 2 , reinforcing ribs 3 are connected around the porous cylindrical koji baskets 6, and the reinforcing ribs 3 are connected to the support frame 1 or the side plates 2. The reinforcing ribs 3 further enhance the connection stability of the porous cylindrical koji baskets 6.
