Description

Technical Field

[0001] The utility model relates to the technical field of brewing, in particular to a koji frame for the accumulation fermentation of 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 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 accumulation fermentation of Jiangxiang Daqu still uses the traditional manual koji setting and stacking method, which requires a large amount of straw, resulting in that processes such as koji setting, koji turning and koji disassembling can only be realized through manual operation. During the traditional koji block accumulation fermentation process, the fermentation temperatures, moisture contents, etc. of the upper, middle and lower layers and the outer and inner layers of the koji blocks are inconsistent. After fermentation 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. At the same time, a large amount of waste straw is generated, which limits 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 accumulation fermentation method, the technical problem to be solved by the utility model is to provide a koji frame for the accumulation fermentation of Jiangxiang Daqu that is helpful for mechanized koji turning.

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

[0005] The koji frame for the accumulation fermentation of 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. Legs are provided 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.

[0006] Further, the support frame includes a plurality of vertical columns arranged at intervals around the partition plates, and a plurality of cross beams connected between the vertical columns.

[0007] Further, the side plates are mesh plates laid between the vertical columns and the cross beams on the sides of the support frame.

[0008] Further, a plurality of door plates made of mesh plates are provided on each of the front and rear sides of the support frame. The door plates are connected to the vertical columns through hinges on the left or right side, or are connected to the cross beams through hinges on the upper or lower side.

[0009] Furthermore, the partition board includes an outer frame, a plurality of support rods arranged vertically and horizontally within the outer frame, and a perforated plate laid on the outer frame and the support rods.

[0010] Furthermore, heat-insulating and moisture-keeping 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.

[0011] Furthermore, the support frame, the side plates, the door plate and the partition board are all made of stainless steel.

[0012] Furthermore, the heat-insulating and moisture-keeping layer is a straw curtain or a fiber curtain.

[0013] The beneficial effects of the present utility model are as follows: by arranging multiple partition boards at intervals to place the koji blocks for stacking and culturing fermentation, the space utilization rate of the fermentation room can be improved. At the same time, the side plates, the door plate and the partition board with a hollow structure are beneficial 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. Even without turning the koji, the production of sauce-flavored Daqu can be achieved; an automated transfer robot can also be used to transfer the koji frames to the fermentation room for dense stacking or turn the koji frames by 180° to achieve the koji-turning operation, which can significantly reduce the labor intensity of workers and is conducive to the mechanized, automated, large-scale and standardized production of sauce-flavored Daqu.

[0018] The present utility model will be further described below with reference to the drawings.

[0019] 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 position relationship 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 position relationship and movement conditions between various components in a specific posture. If this specific posture changes, the directional indication will also change 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.

[0020] As Figure 1 、 Figure 2 As shown, the sauce-flavored Daqu stacking fermentation koji frame of the present utility model includes a support frame 1, side plates 2, door plates 3, and partition plates 4. The side plates 2 are arranged on the left and right sides of the support frame 1. The door plates 3 are movably arranged on the front and back sides of the support frame 1. There are multiple partition plates 4 which are arranged at intervals in the vertical direction within the support frame 1. Adjacent two partition plates 4, together with the side plates 2 and door plates 3, enclose a containing cavity. Legs 5 are 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, door plates 3, and partition plates 4 are all of a hollow structure.

[0021] 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 containing cavity to ensure that there is a certain ventilation space reserved between each layer of koji blanks. The side plates 2, door plates 3, and partition plates 4 are all of a hollow structure, which can facilitate oxygen ventilation and waste discharge, and realize the gas circulation and exchange during the koji blank stacking and culturing fermentation process. According to the space of the fermentation room and the requirements of heat preservation, moisture retention in the early stage of fermentation and moisture discharge in the later stage, while taking into account the space utilization rate, six layers of partition plates 4 can be provided on one koji frame. Since the permeability of this fermentation koji frame is good, as long as the ventilation and moisture discharge effects are ensured, a better-fermented Daqu can be obtained even without koji turning. At the same time, this fermentation koji frame can also cooperate with koji turning equipment for koji turning operations. For example, the koji frame can be grasped by a robotic arm and rotated 180°, and supported by the legs 5 at the upper and lower ends of the support frame 1, so as to realize the exchange of upper and lower koji, and avoid the problem of different fermentation degrees of koji blanks caused by uneven temperature and humidity in the fermentation room space.

[0022] Regarding the specific structure of the fermentation koji frame, the present utility model provides the following preferred solutions:

[0023] To ensure the stability of the overall structure of the fermentation koji frame and not affect the fermentation of koji blanks, it is preferably that the support frame 1, side plates 2, door plates 3, and partition plates 4 are all made of stainless steel.

[0024] To facilitate the stacking of the support frame 1, a cuboid frame structure can be adopted. The frame consists of multiple uprights 11 spaced around the partition 4 and multiple crossbeams 12 connected between the uprights 11. Specifically, six uprights 11 and four crossbeams 12 can be used. Four of the uprights 11 are located on the four prisms of the cuboid frame, and the other two uprights 11 are located in the middle of the long sides. The four crossbeams 12 are arranged in the middle of the uprights 11 to connect all the uprights 11 together. After installing the support frame 1, the partition 4 is fixed inside the support frame 1.

[0025] After the partition 4 is installed, the side plate 2 can be installed. The side plate 2 is a mesh plate and can be directly laid between the uprights 11 and crossbeams 12 on the side of the support frame 1.

[0026] For the door panel 3, to ensure the stability of the connection, it is best to set multiple door panels 3 on both the front and back sides of the support frame 1. Because the door panel 3 is too large, it is easy to deform and cannot prevent the curved blank from falling through the gap. The door panel 3 is also made of a mesh plate. There are two installation methods for the door panel 3. The first is as Figure 1 shown, the door panel 3 is connected to the crossbeam 12 through the hinge 31 on the upper or lower side; the second is as Figure 3 shown, the door panel 3 is connected to the upright 11 through the hinge 31 on the left or right side. Of course, a lock structure needs to be set on the side of the door panel 3 far from the hinge 31 to ensure the stable connection between the door panel 3 and the support frame 1 in the closed state.

[0027] The specific structure of the partition 4 is as Figure 2 shown, 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 4, as long as it can ensure that the mesh plate 43 can bear the weight of the curved blank without deformation.

[0028] In addition, to prevent the curved 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 curved blank, a heat and moisture preservation layer is provided on the inner sides of the side plate 2 and the door panel 3, as well as on the upper and lower surfaces of the partition 4. The heat and moisture preservation layer can be a curtain layer made of straw curtain or fiber material. Specifically, it can be fixed on the side plate 2, the door panel 3, and the partition 4 by tying or pasting to prevent it from falling off during the process of turning the curved blank.
