[0025] During the production process in the koji-making workshop, in the process of koji making and dismantling, the cover at the entrance of the fermentation chamber tunnel needs to be removed so that the entrance can be opened to discard the koji. The current cover is a single movable iron plate weighing 17.4KG, which is difficult for employees to lift. In addition, during the process of discarding the koji, the koji pieces are prone to rolling onto the wall, thus damaging the wall.

[0026] To solve the above problems, refer to Figures 1-2 , Figure 1 This illustration shows a top view of a fermentation chamber provided in an embodiment of this application. Figure 2 This is a cross-sectional view of a fermentation chamber provided in an embodiment of this application.

[0027] This application provides a fermentation chamber with an opening 1 near a wall 2. The fermentation chamber includes a frame 3, a cover 4, and a fixing assembly 5. The frame 3 is located at the opening 1, and has a first step 31 recessed from the frame 3. The cover 4 is located inside the frame 3 and at the first step 31, so that the cover 4 is flush with the surface of the opening 1. The side of the cover 4 facing the wall 2 is rotatably connected to the frame 3, and the cover 4 is provided with a handle 41. The fixing assembly 5 is located on the wall 2. Component 5 includes a base plate 51, an adjusting component 52, and a fixing component 53. The base plate 51 is fixed to the wall 2, and the adjusting component 52 passes through the fixing component 53 and is threadedly connected to the base plate 51. In the first state, the cover 4 is located at the first step 31, and the opening 1 is closed. In the second state, the cover 4 rotates relative to the frame 3, and the cover 4 abuts against the base plate 51. The adjusting component 52 is rotated so that the cover 4 is located between the base plate 51 and the fixing component 53, so that the opening 1 is opened and the impact of the curved block on the wall 2 is reduced.

[0028] It should be understood that the fermentation chamber is provided with an opening 1. This application does not limit the shape of the opening 1; the opening 1 can be circular, rectangular, or any other arbitrary shape. The curved block is inserted through the opening 1. The opening 1 is close to the wall 2. A frame 3 and a cover 4 are provided at the opening 1, and both the frame 3 and the cover 4 are conformally designed to fit the opening 1. In one example, the opening 1 is rectangular, the frame 3 is also rectangular, and the cover 4 is rectangular. The frame 3 is connected to the opening 1, which can be done by casting or other methods; this application does not impose any restrictions. When the frame 3 is connected to the opening 1, the upper surface of the frame 3 is flush with the upper surface of the opening 1 to avoid creating obstacles. Both the frame 3 and the cover 4 are made of metal to reduce the probability of deformation and improve their service life.

[0029] The inner wall of the frame 3 has a recessed first step 31. The material of the first step 31 is the same as that of the frame 3, and it can be connected by integral molding or welding, etc., which is not limited in this application. The cover 4 is located in the frame 3 and at the first step 31. When the cover 4 closes the opening 1, the upper surface of the cover 4 is flush with the upper surface of the opening 1 to avoid creating a road obstruction. The end of the cover 4 facing the wall 2 is rotatably connected to the frame 3, which can be connected by a hinge. When the cover 4 needs to be opened, it is rotated so that the cover 4 abuts against the wall, thereby opening the opening 1.

[0030] To facilitate the operator in opening the cover 4, a handle 41 is provided on the top of the cover 4, which makes it easier for the operator to hold and improves the convenience of operation.

[0031] A fixing component 5 is also provided at wall 2. The fixing component 5 includes a base plate 51, an adjusting member 52, and a fixing member 53. The base plate 51 is plate-shaped and fits against wall 2. The base plate 51 is connected to wall 2 by bolts. One end of the adjusting member 52 passes through the fixing member 53 and is threadedly connected to the base plate 51. The adjusting member 52 can be a bolt. The fit between the fixing member 53 and the base plate 51 can be controlled by rotating the adjusting member 52. This application does not limit the shape of the fixing member 53. The fixing member 53 can be strip-shaped or plate-shaped. In one example, the fixing member 53 is plate-shaped.

[0032] In the first state, the cover 4 is located at the first step 31, and the opening 1 is closed to facilitate the sealing of the fermentation chamber and also to prevent the operator from falling into the opening 1.

[0033] In the second state, when it is necessary to load koji blocks into the fermentation chamber, the operator holds handle 41 and rotates the cover 4 so that the cover 4 abuts against the wall 2. The operator then rotates the adjusting component 52 so that the fixing component 53 and the base plate 51 clamp the cover 4. The operator then rotates the adjusting component 52 again to improve the stability of the clamping of the cover 4 by the fixing component 53 and the base plate 51, preventing the cover 4 from falling over. At this time, the trolley containing the koji blocks can be moved to the opening, and the trolley can be tilted so that the koji blocks enter the opening 1. Due to inertia, the koji blocks will hit the cover 4 during entry, and the cover 4 can protect the wall 2, thus preventing damage to the wall 2. To more accurately pour the koji blocks and improve the accuracy of the impact of the koji blocks on the cover 4, a positioning groove adapted to the trolley can be provided at the opening 1.

[0034] After the curved block is filled, the adjusting part 52 can be rotated to disengage the fixing part 53 from the cover 4, and the cover 4 will cover the opening 1.

[0035] The cover 4 of this application is designed so that the operator can open the opening 1 by flipping the cover 4 with the handle 41 and fix the cover 4 with the fixing component 5. This eliminates the need for the operator to move the cover 4, reducing the operator's workload. At the same time, the cover 4 can shield the wall 2, reducing the impact of the curved block on the wall 2 during the dropping process, thereby protecting the wall 2.

[0036] In some optional embodiments, the fixing member 53 includes an abutting portion 531 and a engaging portion 532 connected to each other. The abutting portion 531 abuts against the base plate 51, and the adjusting member 52 passes through the abutting portion 531 and is threadedly connected to the base plate 51. The engaging portion 532 is spaced apart from the base plate 51 to engage the cover 4. The abutting portion 531 and the engaging portion 532 are made of the same material and are integrally formed. The abutting portion 531 can improve the fit between the fixing member 53 and the base plate 51 and improve the effect of the adjusting member 52 in controlling the fixing member 53. The engaging portion 532 is spaced apart from the base plate 51 to better clamp the cover 4 and improve the clamping effect on the cover 4.

[0037] In some optional embodiments, the handle 41 is located on the side of the cover 4 away from the wall 2, and the handle 41 is rotatably connected to the cover 4, with the handle 41 fitting against the cover 4. The handle 41 can be located at any position on the upper surface of the cover 4, or it can be located near the wall 2. This application does not impose any restrictions, but when the handle 41 is located on the cover 4 away from the wall 2, it is more convenient for the operator to hold the handle 41 and to rotate the cover 4, improving the convenience of the operator's operation. The handle 41 is rotatably connected to the cover 4. When the handle 41 is not needed, the handle 41 fits against the cover 4, avoiding obstruction and affecting the operator. At the same time, when the operator flips the cover 4, the handle 41 also fits against the cover 4, without affecting the cover 4 being clamped by the fixing member 53 and the base plate 51.

[0038] In some alternative embodiments, the opening 1 is recessed with a second step 11, the frame 3 is located at the second step 11, and the first step 31 is higher than the second step 11. The second step 11 is provided so that the frame 3 is flush with the opening 1, avoiding obstruction. The first step 31 is higher than the second step 11, so that the cover 4 is located above the second step 11.

[0039] In some alternative embodiments, the cross-section of the first step portion 31 is "U" shaped, that is, the first step portion 31 is hollow. Compared with the first step portion 31 being solid, this application reduces the weight of the first step portion 31, making it easier for the operator to handle or install. At the same time, it also reduces the material of the first step portion 31, thereby saving the manufacturing cost of the first step portion 31.

[0040] Reference Figures 2-4 , Figure 3This illustration shows a top view of a grid frame provided in an embodiment of this application. Figure 4 This diagram shows a cross-sectional view of a grid frame provided in an embodiment of this application. In some optional embodiments, a grid frame 6 is also included. The grid frame 6 is located inside the frame 3 and abuts against the second step portion 11. The height of the grid frame 6 is lower than or flush with the first step portion 31. The grid frame 6 is located at the second step portion 11, that is, below the cover 4. The placement of the grid frame 6 does not affect the closing of the cover 4. With the grid frame 6 placed at the second step portion 11, when it is necessary to put koji blocks into the fermentation chamber, the cover 4 is first flipped open, and then the grid frame 6 is removed from the opening 1 to facilitate the placement of koji blocks. When it is necessary to ventilate the fermentation chamber, the cover 4 can be flipped open first, leaving the grid frame 6 at the opening 1. The placement of the grid frame 6 does not affect the ventilation of the fermentation chamber, and at the same time, it can prevent operators or foreign objects from falling into the fermentation chamber, thereby improving safety.

[0041] Reference Figure 3 and Figure 4 In some optional embodiments, the mesh frame 6 includes a support frame 61 and a breathable mesh 62. The support frame 61 includes a horizontal portion 611 and a vertical portion 612 connected to each other. The breathable mesh 62 is located in the support frame 61, below the horizontal portion 611, and its periphery is connected to the horizontal portion 611. The support frame 61 is conformally configured to the opening 1. When the opening 1 is rectangular, the support frame 61 is also rectangular. The support frame 61 includes a horizontal portion 611 and a vertical portion 612. The horizontal portion 611 and the vertical portion 612 are made of the same material and are integrally formed. The vertical portion 612 is located on the outer periphery of the horizontal portion 611. To improve the strength of the mesh frame 6, the mesh frame 6 is made of metal. The breathable mesh 62 has multiple mesh holes. This application does not limit the shape of the mesh holes; the mesh holes can be diamond-shaped, circular, or rectangular, etc. The periphery of the breathable mesh 62 is located below the horizontal portion 611, and the periphery of the breathable mesh 62 is connected to the horizontal portion 611. The horizontal portion 611 increases the contact area between the breathable mesh 62 and the support frame 61, thereby improving the stability of the connection between the breathable mesh 62 and the support frame 61. Furthermore, the horizontal portion 611 is located above the breathable mesh 62, protecting the connection between the breathable mesh 62 and the horizontal portion 611, further enhancing the stability of the connection between the breathable mesh 62 and the support frame 61. The breathable mesh 62 is made of metal to increase its strength and service life.

[0042] In some optional embodiments, the mesh frame 6 further includes reinforcing ribs 63 located below the breathable mesh 62 and connected to the vertical portion 612. The reinforcing ribs 63 are elongated strips, and can be cylindrical or cuboid in shape; this application does not impose any limitation. Located below the breathable mesh 62, the reinforcing ribs 63 provide support and improve the strength of the breathable mesh 62. Both ends of the reinforcing ribs 63 along their length are connected to the vertical portion 612, and the connection method can be welding or integral molding, etc.; this application does not impose any limitation.

[0043] In some optional embodiments, multiple reinforcing ribs 63 are provided, and the multiple reinforcing ribs 63 are spaced apart along the length and / or width direction of the breathable mesh 62. The provision of multiple reinforcing ribs 63 can further improve the strength of the breathable mesh 62.
