Description

Technical Field

[0001] The utility model relates to the technical field of brewing, in particular to a detachable stacking fermentation koji frame for Jiangxiang Daqu. Background Art

[0002] Jiangxiang Daqu provides the bacterial system, enzyme system and material system required for the production of Jiangxiang-flavor Baijiu, and makes an important contribution to the style and quality of Jiangxiang-flavor Baijiu. The production process of Jiangxiang Daqu mainly includes: wheat moistening, wheat crushing, addition of mother koji, water addition and mixing, koji block forming, koji airing, koji placing and stacking fermentation in the workshop, koji turning, and koji disassembling and storage. From wheat moistening to koji block forming, mechanization or automation has been basically achieved, while the stacking fermentation of Jiangxiang Daqu 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 disassembling can only be realized manually. During the traditional koji block stacking fermentation process, 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 part to the lower part and the inner part to the outer part 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 and humidity in the fermentation workshop are high and the dust is large, with a harsh working environment. At the same time, a large amount of waste rice straw is generated, which restricts the high-efficiency, mechanized and automated production of Jiangxiang Daqu. Summary of the Utility Model

[0003] In order to overcome the above-mentioned deficiencies existing in the existing stacking fermentation method, the technical problem to be solved by the utility model is to provide a detachable stacking fermentation koji frame for Jiangxiang Daqu that is helpful for mechanized koji turning.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] The detachable stacking fermentation koji frame for Jiangxiang Daqu includes a support frame, side plates, a door plate and partition plates. The side plates are arranged on the left and right sides of the support frame. The door plate is movably arranged on the front and rear sides of the support frame. The partition plates include a plurality of them and are arranged at intervals in the vertical direction in the support frame. An accommodating cavity is enclosed by two adjacent partition plates, the side plates and the door plate. Guide positioning blocks and pins that can be inserted into each other are respectively arranged on the outer sides of the partition plates at the upper and lower ends of the support frame. The side plates, the door plate and the partition plates are all of a hollow structure; a plurality of support frames can be overlapped together through the insertion and cooperation of the guide positioning blocks and the pins.

[0006] Further, the support frame includes a plurality of upright columns arranged at intervals around the partition plates.

[0007] Further, the side plate is a mesh plate laid between the upright columns on the side of the support frame and the ends of the partition plates.

[0008] Furthermore, on both the front and rear sides of the support frame, there are multiple door panels made of mesh plates. The door panels are connected to the columns through hinges on the left or right side, or are connected to the side surfaces of the partition through hinges on the upper or lower side.

[0009] Furthermore, the partition includes an outer frame, multiple support rods arranged crisscross within the outer frame, and a mesh plate laid on the outer frame and the support rods.

[0010] Furthermore, each koji fermentation frame has no more than four partitions, and every two koji fermentation frames are overlapped together as a group of koji fermentation frames.

[0011] Furthermore, heat-insulating and moisture-preserving layers are provided on the inner side surfaces of the side plates and door panels, as well as on the upper and lower surfaces of the partition.

[0012] Furthermore, the support frame, side plates, door panels, and partition are all structures made of stainless steel.

[0013] Furthermore, the heat-insulating and moisture-preserving layer is a straw curtain or a fiber curtain.

[0014] The beneficial effects of the present utility model are as follows: By arranging koji blanks through multiple spaced partitions for stacking and culturing fermentation, the space utilization rate of the fermentation room can be improved. At the same time, the side plates, door panels, and partitions with a hollow structure are conducive to air flow, which helps with heat preservation and moisture retention in the early stage of stacking fermentation and moisture discharge in the later stage; these koji fermentation frames can be used overlapped in multiple numbers, and the koji frames can be transferred to the fermentation room for dense stacking by an automated transfer robot, and the positions of the upper and lower koji fermentation frames can also be swapped by a robotic arm to achieve the koji turning operation, which can significantly reduce the labor intensity of workers and is beneficial to the mechanized, automated, large-scale, and standardized production of Jiangxiang Daqu.

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

[0021] It should be noted that if there are directional indication terms involved in the present utility model, such as the directional and azimuth terms of up, down, left, right, front, and back, they are for facilitating the description of the relative positions between components, rather than specifically referring to the absolute positions of relevant components and the positional relationships between components. They are only used to explain the relative positional relationships and movement conditions between components in a specific posture. If this specific posture changes, then the directional indication also changes accordingly. If there are terms related to quantity in the present utility model, such as "many", "multiple", "several", etc., specifically refer to two or more.

[0022] As Figure 1 、 Figure 2 shown, the sauce-flavored Daqu detachable stacking fermentation koji frame of the present utility model includes a support frame 1, side plates 2, a door plate 3, and partition plates 4. The side plates 2 are arranged on the left and right sides of the support frame 1, the door plate 3 is arranged on the front and back sides of the support frame 1 in an openable manner, the partition plates 4 are multiple and are arranged at intervals in the vertical direction within the support frame 1. Adjacent two partition plates 4, the side plates 2, and the door plate 3 enclose a receiving cavity. Guide positioning blocks 5 and pins 6 that can be inserted into each other are respectively provided on the outer sides of the partition plates 4 at the upper and lower ends of the support frame 1. The side plates 2, the door plate 3, and the partition plates 4 are all hollow structures; multiple support frames 1 can be overlapped together through the insertion and cooperation of the guide positioning blocks 5 and the pins 6.

[0023] Since the koji blanks in current automated production are generally formed by special equipment, the size of the partition plates 4 and the distance between adjacent partition plates 4 can be designed according to the size of the koji blanks. The koji blanks should be smaller than the volume of the receiving cavity to ensure that there is a certain ventilation space reserved between each layer of koji blanks. The side plates 2, the door plate 3, and the partition plates 4 are all hollow structures, which can facilitate oxygen ventilation and waste discharge, and realize the gas circulation and exchange during the stacking and culturing fermentation process of the koji blanks. The guide positioning block 5 can adopt a horn-shaped sleeve structure with a larger upper opening and a smaller lower opening, so that the insertion and cooperation of the pin 6 and the guide positioning block 5 can be easily achieved when stacking the fermentation koji frames. This fermentation koji frame is mainly used in cooperation with koji-turning equipment for koji-turning operations. During fermentation, in order to improve the space utilization rate and reduce the koji-turning steps at the same time, two fermentation koji frames can be stacked together for fermentation. As Figure 2 shown, after fermentation for a period of time, because the temperature and humidity of the upper and lower layers are different, the fermentation degrees are different. At this time, the upper fermentation koji frame can be removed by a robotic arm and placed on the ground, and then the original lower fermentation koji frame can be placed above the fermentation koji frame on the ground, so that the upper and lower koji can be exchanged, avoiding the problem of different fermentation degrees of the koji blanks caused by uneven temperature and humidity in the fermentation room space.

[0024] For the specific structure of the fermentation koji frame, the present utility model provides the following preferred solutions:

[0025] To ensure the stability of the overall structure of the fermentation koji frame and not affect the fermentation of the koji blank, it is best that the support frame 1, side plates 2, door panels 3, and partition plates 4 are all made of stainless steel.

[0026] To facilitate the stacking of the support frame 1, a cuboid frame structure can be adopted, and the frame is composed of multiple upright columns 11 spaced around the partition plate 4. Specifically, six upright columns 11 can be used, with four upright columns 11 located on the four prisms of the cuboid frame and the other two upright columns 11 located in the middle of the long sides. During installation, marks can be made on the upright columns 11 first, and then the partition plate 4 can be welded to the upright columns 11 according to the marks.

[0027] After the partition plate 4 is installed, the side plates 2 can be installed. The side plates 2 are made of mesh plates and can be directly laid between the upright columns 11 on the side of the support frame 1 and the ends of the partition plate 4.

[0028] For the door panel 3, since multiple fermentation koji frames are stacked during fermentation, the size of a single fermentation koji frame does not need to be too large. Two door panels 3 can be provided on each of the front and rear sides of the support frame 1, and the door panels 3 are also made of mesh plates. The door panel 3 can be installed in two ways. The first is as shown in Figure 1 , where the door panel 3 is connected to the side of the partition plate 4 through a hinge 31 on the upper or lower side; the second is as shown in Figure 4 , where the door panel 3 is connected to the upright column 11 through a hinge 31 on the left or right side. Of course, a locking structure needs to be provided on the side of the door panel 3 away from the hinge 31 to ensure the stable connection between the door panel 3 and the support frame 1 in the closed state.

[0029] The specific structure of the partition plate 4 is as shown in Figure 3 , including an outer frame 41, 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, as long as it can ensure that the mesh plate 43 can bear the weight of the koji blank without deformation.

[0030] In addition, to prevent the koji blank from falling through the through holes of the mesh plate 43 and to meet the temperature and humidity requirements for the fermentation of the koji blank, heat preservation and humidity preservation layers are provided on the inner sides of the side plates 2 and the door panels 3, as well as on the upper and lower surfaces of the partition 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 on the side plates 2, door panels 3, and partition plates 4 by tying or pasting to prevent them from falling off during the koji turning process.
