Description

Technical Field

[0001] This utility model relates to the field of disc-based koji-making technology, specifically to a disc-based koji-making and turning mechanism. Background Technology

[0002] Currently, disc fermentation is a new type of equipment for soy sauce koji making. Disc fermentation offers significant quality and technological advantages over traditional fixed fermentation chambers. However, during the koji-making process, the koji molds generate heat, releasing moisture from the koji material. This released moisture adheres to the flour-based koji on the surface of the molds, gradually forming clumps. At this point, a turning auger is needed to loosen the koji. Disc fermentation equipment is currently favored by large-scale soy sauce manufacturers in China. This equipment allows for large-scale batch feeding, stable koji quality, automated koji feeding and discharging, and precise computer-controlled temperature and humidity.

[0003] During koji making, the koji material needs to be turned over. While existing koji-turning augers have a good turning effect, they cannot directly contact the bottom wall of the koji-making disc, thus only turning over a shallow layer of koji. The effect deteriorates when the koji layer reaches a certain thickness. Furthermore, because the auger doesn't directly contact the bottom wall of the disc, the koji material often doesn't reach the bottom, leading to clumping and insufficient oxygen and moisture, resulting in abnormal koji growth. Forcing the auger blades to directly contact the bottom wall of the koji-making disc to turn the material over can easily scratch both the blades and the disc. Utility Model Content

[0004] The purpose of this invention is to provide a disc-based bending and turning mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The driven shafts are connected to each other by a transmission belt. Limiting parts are fixedly connected to both the driven shaft and the output shaft of the auger gear reducer to prevent the transmission belt from disengaging.

[0012] Preferably, a lifting guide rail is fixedly connected to the outer wall of the disc koji-making machine, and a support slider is fixedly connected to the left side of the lifting beam, the support slider being connected inside the lifting guide rail.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention, by setting up a lifting beam and using a central shaft and lifting ring to adjust the height of the lifting beam, allows for adjustment of the height of the lifting beam at different stages of koji making, enabling the koji material to be turned over. Furthermore, the lifting groove limits the lifting height of the lifting beam, preventing the turning auger from scratching the rotating disc.

[0019] This invention improves koji-making efficiency and the stability of koji quality by setting first, second and third tumbling blades to turn the bottom layer of koji material upward, increase the contact area between the middle layer of dispersed koji material and air, and break up the top layer of koji material to prevent clumping.

[0020] This invention, by setting up geared motors B, C, and D, achieves layered differentiation in material tumbling and improves the quality of koji making by having the inner auger operate at low speed to avoid excessive material compression, the middle auger operate at medium speed to balance tumbling efficiency and force, and the outer auger rotate at high speed to enhance the mixing intensity of the edge area.

[0021] This invention uses a PLC to control the speed of the geared motor A, which ensures that the tumbling auger maintains a stable and consistent speed at different stages of koji making. The stable speed allows the koji material to be evenly turned over in the disc, avoiding local over-turning or under-turning, thus ensuring the stability of koji making quality.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1:

[0035] Please see Figures 1 to 5 , Figures 9 to 10 This utility model provides a technical solution:

[0036] A disc-based koji-making and koji-turning mechanism includes:

[0037] A disc koji-making machine 1 is provided with a feed inlet 2 and a discharge outlet 3. A central base 5 is provided at the center of the bottom inner side of the disc koji-making machine 1. A continuously rotating rotary disc 4 is provided on the outer side of the central base 5. A fixed support column 6 is fixedly connected to the upper end face of the central base 5.

[0038] A central shaft 7 is rotatably connected inside a fixed support column 6. A lifting ring 802 is threaded onto the central shaft 7. A connecting plate 803 is fixedly connected to the side of the lifting ring 802. The connecting plate 803 passes through a lifting groove 601 opened on the fixed support column 6 and is connected to a lifting beam 8. A turning component is provided at the bottom of the lifting beam 8 for turning the curved material on the rotary disc 4.

[0039] Specifically, the rotary disc 4 is made of stainless steel and has good flatness and roundness to ensure that there is no material leakage during rotation. The bottom of the disc is equipped with a drive device, which is a combination of motor and reducer. The drive device drives the rotary disc 4 to rotate smoothly around the central base 5 through gear or chain transmission 15.

[0040] Specifically, each component of the disc koji-making machine 1 is automatically controlled by an integrated PLC, and in conjunction with the sensors inside the disc koji-making machine 1, it completes functions such as automatic feeding, discharging, koji turning, and temperature control, and starts and stops in an orderly manner, reducing labor intensity and manual operation.

[0041] Specifically, the bending assembly includes a bending auger 10, which is rotatably connected to the lower end face of the lifting beam 8.

[0042] Specifically, the lifting beam 8 is internally fixedly connected to a reduction motor B17, a reduction motor C1701, and a reduction motor D1702. The reduction motor B17 is rotatably connected to the outer ring auger 10 through a transmission gear set 1703. The reduction motor C1701 is rotatably connected to the outer ring auger 10 through a transmission gear set 1703. The reduction motor D1702 is rotatably connected to the outer ring auger 10 through a transmission gear set 1703.

[0043] In this embodiment, as Figure 9 The lifting beam integrates geared motors B17, C1701, and D1702. The motor speeds are precisely controlled by a PLC. Each motor is connected to its corresponding auger 10 via a transmission gear set 1703, achieving precise transmission. The inner auger 10 is driven by geared motor D1702 to maintain a slow speed, suitable for gently turning materials and avoiding excessive compression. The middle auger 10 operates at a medium speed driven by geared motor C1701, balancing turning force and efficiency. The outer auger 10 rotates rapidly driven by geared motor B17, effectively enhancing the turning intensity at the material edges and ensuring uniform mixing of materials.

[0044] Specifically, a drive motor 701 is fixedly connected to the top of the disc koji-making machine 1, and the central shaft 7 is rotatably connected to the output end of the drive motor 701.

[0045] Specifically, a lifting guide rail 9 is fixedly connected to the outer wall of the disc koji-making machine 1, and a support slider 801 is fixedly connected to the left side of the lifting beam 8. The support slider 801 is connected inside the lifting guide rail 9.

[0046] In this embodiment, after the drive motor 701 at the top of the disc maker 1 is started, it drives the central shaft 7 to rotate. Since the central shaft 7 is threadedly connected to the lifting ring 802, the lifting ring 802 will move linearly along the axial direction of the central shaft 7. The connecting plate 803 fixedly connected to its side passes through the lifting groove 601 of the fixed support column 6 and transmits the linear movement of the lifting ring 802 to the lifting beam 8, so that the lifting beam 8 rises or falls in the lifting groove 601 to adjust the height of the auger 10.

[0047] In the early stages of koji making, when the koji material is thick, the tumbling auger 10 is first raised to a high position to loosen the upper layer of koji material significantly, preventing the surface koji from sticking together with moisture and forming clumps. As the koji material ferments and shrinks, the tumbling auger 10 is lowered to close to the bottom wall of the disc by the central shaft 7 and the lifting ring 802, loosening the deeper material and eliminating the risk of clumping. At the same time, the height of the tumbling auger 10 is precisely controlled by the depth limit of the lifting groove 601 and the PLC to prevent the auger from scratching the rotating disc 4.

[0048] Specifically, a material spreading pipe 201 is fixedly connected to the outer surface of the fixed support 6. The material spreading pipe 201 passes through the feed inlet 2 to the outside of the disc koji-making machine 1 and is used to spread koji material on the rotating disc 4.

[0049] Specifically, the material feeding pipe 201 includes a feeding hopper, a feeding pipe and a feeding device. The feeding device generally adopts a mature screw feeder or vibrating feeder, which can accurately control the feeding speed and amount of the material and ensure that the material enters the rotating disc 4 evenly.

[0050] Specifically, a discharge pipe 301 is fixedly connected to the outer surface of the fixed support 6, and the discharge pipe 301 passes through the discharge port 3 to the outside of the disc koji maker 1.

[0051] Specifically, the unloading pipe 301 has horizontally arranged spiral auger blades that gradually push the inner ring of curved material toward the outer unloading port 3 for discharge.

[0052] Specifically, a driven gear 401 is fixedly connected to the outer ring of the rotary disk 4, and a disk gear reducer 16 is fixedly connected to the outer wall of the disk koji maker. The output end of the disk gear reducer 16 is rotatably connected to a driving gear 1601, and the driving gear 1601 meshes with the driven gear 401.

[0053] In this embodiment, as Figure 10 The motor inside the disc gear reducer 16 drives the reducer via a chain. The output end of the reducer drives the rotary disc 4 to rotate continuously via the drive gear 1601, so that the material passes through the auger 10.

[0054] Example 2:

[0055] Please see Figure 5 This utility model provides a technical solution that is basically the same as that in Embodiment 1, with the following slight differences:

[0056] Specifically, a reduction motor A11 is fixedly connected inside the lifting beam 8, and the output end of the reduction motor A11 is rotatably connected to the auger 10.

[0057] In this embodiment, the auger 10 can be selected from another structure (such as...). Figure 5 The lifting beam 8 has multiple geared motors A11 fixedly connected inside. The output end of the geared motor A11 is rotatably connected to the tumbling auger 10. The number of geared motors A11 is the same as the number of tumbling augers 10. The geared motors A11 are precisely controlled by the PLC control system, which can ensure that the tumbling auger 10 maintains a stable and consistent speed at different stages of koji making. The stable speed can make the koji material be turned evenly in the disc, avoiding local over-turning or under-turning, and ensuring the stability of koji making quality.

[0058] Example 3:

[0059] Please see Figure 6 This utility model provides a technical solution that is basically the same as that in Embodiment 1, with the following slight differences:

[0060] Specifically, a auger gear reducer 12 is fixedly connected inside the lifting beam 8, and a driven shaft 13 is fixedly connected to the upper end face of the auger 10. The driven shafts 13 are connected to each other by a transmission belt 15. Limiting parts 14 are fixedly connected to both the driven shafts 13 and the output shaft of the auger gear reducer 12 to prevent the transmission belt 15 from disengaging.

[0061] In this embodiment, the auger 10 can be selected from another structure (such as...). Figure 6 The motor is connected to the auger gear reducer 12, and the output is transmitted through the auger gear reducer 12. Multiple augers 10 are controlled by one motor, which reduces equipment costs and the number of related electrical control components, reduces the probability of failure, and makes management and maintenance easier. The transmission belt 15 maintains a stable and consistent speed. The stable speed can make the koji material be turned evenly in the disc, avoiding local over-turning or under-turning, and ensuring the stability of koji production quality.

[0062] Example 4:

[0063] Please see Figures 7 to 8 This utility model provides a technical solution:

[0064] Specifically, the folding assembly includes a folding auger 10, which is rotatably connected to the lower end face of the lifting beam 8. The bottom of the folding auger 10 has a spiral first folding blade 1001, a second folding blade 1002 is disposed above the first folding blade 1001, and a third folding blade 1003 is disposed above the second folding blade 1002.

[0065] Specifically, the shape of the third turning blade 1003 is not fixed; different blade models can be selected according to requirements to achieve the effect of crushing the koji material (e.g., Figure 8 ).

[0066] In this embodiment, the lower half of the auger 10 has a first auger blade 1001, which is a continuous spiral blade that generates an upward thrust during rotation, tumbling the bottom layer of material upward. A second auger blade 1002 is located above the first auger blade 1001, and its blade surface has notches (such as...). Figure 7 This allows the rising koji material to disperse in all directions under the action of centrifugal force, and the gaps allow more air to enter the koji material layer, increasing the contact area between the koji material and the air.

[0067] The third folding blade 1003 is located above the second folding blade 1002 and features a serrated edge design (e.g., ...). Figure 7 During operation, the lifting beam 8 drives the auger 10 to insert into the koji material. When the auger 10 rotates at high speed, the larger koji material blocks on the upper layer will be crushed by the shearing and collision action of the edge of the third auger blade 1003, ensuring that the koji material has a uniform particle size. The three auger blades work together to turn the bottom koji material upward, increase the contact area between the middle layer of dispersed koji material and air, and crush the upper layer of koji material to prevent clumping, thereby improving the koji making efficiency and the stability of koji material quality.

[0068] In use, this utility model is controlled by PLC to start the rotary disc 4. The fermented material is evenly spread on the rotary disc 4 through the feed port 2 and the spreading pipe 201. The top drive motor 701 is started, which drives the central shaft 7 to rotate, so that the lifting beam 8 adjusts the tumbling auger 10 to descend and insert into the fermented material to carry out the tumbling work. As the fermented material shrinks during fermentation, the drive motor 701 is controlled to adjust the central shaft 7, so that the lifting beam 8 drives the tumbling auger 10 to descend and loosen the deep material. The descent height of the lifting beam 8 is limited by the lifting groove 601 to avoid scratching the disc. After the fermentation is completed, the spiral auger blades of the discharge pipe 301 discharge the fermented material from the discharge port 3.

[0069] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0070] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
