Description

Technical Field

[0001] This utility model belongs to the field of pressing koji cakes in the winemaking industry, specifically relating to a high-efficiency koji-making machine. Background Technology

[0002] In the brewing industry, koji (fermentation starter) is the core "saccharification and fermentation agent" for brewing fermentation. Its quality and preparation efficiency directly determine the taste, flavor and production scale of the liquor. Therefore, the koji making process is a key preliminary step in the brewing process. The traditional koji making process is mainly based on manual treading. Operators need to be barefoot to tread the mixed loose koji material, which is mostly a mixture of grain raw materials and microorganisms, into the mold. By manually controlling the force and density, the koji material is formed into koji blocks of specific shapes, such as bricks or cakes, and then enters the fermentation process.

[0003] Currently, the brewing industry typically uses manual treading to produce koji (fermentation starter). However, this method relies on manual labor to press each koji individually, with a single worker only able to produce a few dozen pieces per day. In contrast, medium to large-sized breweries often require thousands or even tens of thousands of koji pieces per batch. Furthermore, the koji-making cycle is limited by the fermentation process, requiring intensive pressing within a short period to ensure the activity of the microorganisms. This manual method easily leads to a production contradiction of "high demand and tight schedule," thus restricting the brewery's capacity expansion. Manual treading also demands a high level of skill, ensuring uniform koji density—too loose and it crumbles, too tight and it affects fermentation. Therefore, long-term training is necessary to master the technique. Large-scale koji production requires a significant investment of manpower, with hundreds of people potentially working simultaneously on a single batch. As labor costs continue to rise, the production burden on enterprises increases significantly. During the manual barefoot treading process, human sweat, skin impurities, and external pollutants can easily mix into the koji material, directly affecting the purity of the microbial strain and fermentation stability. The force and density of manual treading depend on individual experience, and differences in operation between different workers, or even the same worker at different times, can lead to uneven koji block density and inconsistent shapes. The density of the koji blocks directly affects the aeration and temperature and humidity distribution during fermentation, ultimately causing fluctuations in the quality of the koji material and making it difficult to meet the standardized requirements of modern brewing materials. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency koji-making machine. This device can improve the outdated process of manually stepping on koji during the brewing process. By automatically pressing the koji into blocks and mechanically clamping and pushing it, it effectively solves the core contradiction of short koji-making time and large koji material demand, greatly improving koji-making efficiency, saving manpower, material resources and koji-making time, and eliminating the hygiene hazards caused by manual barefoot treading of koji. It improves the hygiene of koji-making from the source, while ensuring that the koji blocks are intact and forming, creating a more stable fermentation environment for the koji-making strains, helping the strains to better reproduce and metabolize, thereby improving the quality of the koji and providing high-quality raw materials for subsequent brewing.

A travel support plate is fixedly connected to the bottom end of the two guide rods and located at the bottom of the table panel. A circular hole is formed at the top of the travel support plate. A rectangular groove is formed at the top of the table panel and located at the bottom of the material box cavity. Two sliding holes are formed in the rectangular groove. A first ejector pin is slidably connected to the inner wall of each of the two sliding holes. A finished product top plate is fixedly installed on the top of each of the first ejector pins and inside the rectangular groove. A finished product bottom plate is fixedly connected to the bottom of the two first ejector pins. A second ejector pin is fixedly connected to the bottom of the finished product bottom plate, and the surface of the second ejector pin is slidably connected to the circular hole. A first pulley is rotatably connected to the top of the upper support plate. The surface of the moving screw is slidably connected to the inner wall of the first pulley. A motor is fixedly installed on one side of the upper support plate. A second pulley is fixedly installed at the output end of the motor. A conveyor belt is rotatably connected between the first pulley and the second pulley. A movable limit component is provided on the stroke support plate.

[0007] Preferably, the movable limiting component includes rectangular plates fixedly connected to both sides of the top of the travel support plate, one of the rectangular plates having a rod inserted into one side, the rod having an I-shaped structure, a first spring fixedly connected to the side of the rod that is close to the rectangular plate and the first spring being sleeved on the surface of the rod, and the bottom of the second ejector pin having a hole for cooperating with the rod.

[0008] Preferably, the clamping and pushing assembly includes strip grooves formed on both sides of the top of the table panel. Sliding support plates are slidably connected to each of the two strip grooves. A U-shaped push plate is fixedly connected to the top of each of the two sliding support plates. Strip holes are formed on both sides of each U-shaped push plate. A T-shaped rod is slidably connected to each of the strip holes. Rectangular pressure plates are fixedly connected to opposite sides of each of the two T-shaped rods. A first rack is fixedly connected to the side of each rectangular pressure plate closest to the T-shaped rod. Gears are fixedly connected to both sides of the top of the U-shaped push plate, with the top of one side of the gear meshing with one side of the first rack. An electric push rod is fixedly installed on the top of the table panel. A U-shaped toothed push rod is fixedly connected to the piston rod of the electric push rod. The two sides of the inner wall of the U-shaped toothed push rod mesh with the bottom of one side of the gear.

[0009] Preferably, the top and bottom of the gear are rotatably connected to rotating connecting blocks, and each of the first racks has a first sliding groove on the top side near the gear. The top rotating connecting blocks are slidably connected in the first sliding groove, and the top and bottom rotating connecting blocks are slidably connected in the second sliding groove.

[0010] Preferably, each of the T-shaped rods has a limiting block slidably connected to the surface of the side away from the rectangular pressure plate, and a sliding rod is slidably connected to the bottom of each limiting block. Both ends of the sliding rod are fixedly connected to a strip rod, and the bottom of the strip rod is fixedly connected to the top of the table panel. One side of one of the strip rods has an inverted L-shaped structure, and a second spring is fixedly connected to the side of one of the strip rods that is close to the limiting block, and the second spring is sleeved on the surface of the sliding rod.

[0011] The technical effects achieved by this utility model are as follows: This utility model discloses a high-efficiency koji-making machine. By setting up a koji-forming block assembly and a clamping and pushing assembly, a drive motor drives a second pulley to rotate in the opposite direction, which in turn causes the conveyor belt and the first pulley to rotate counterclockwise. Simultaneously, this drives the moving screw and the pressure head to move upwards. When the finished product bottom plate overlaps with the table panel, the finished product top plate overlaps with the top of the material box, completing the material discharge. This replaces the traditional manual barefoot koji-making process, thus improving koji-making efficiency. After discharge, the control panel drives an electric push rod to move a U-shaped toothed push rod towards a U-shaped push plate. The U-shaped toothed push rod drives the gear meshing with it to rotate. The gear rotation then drives the first rack meshing with it to move. The movement of the first rack then causes the rectangular pressure plates on both sides of the U-shaped push plate to move closer together. The rectangular pressure plates drive T-shaped rods to slide within the strip holes. The relative movement of the two T-shaped rods, through the rectangular pressure plates, presses the koji blocks at the top of the material box. The device employs a clamping mechanism where, while rectangular pressure plates clamp the material, gears drive a U-shaped pusher plate closer to the rectangular pressure plates. This pusher plate, via a U-shaped toothed push rod, moves the entire clamping and pushing assembly, pushing the clamped koji blocks from the top of the material box. This ensures the koji blocks are accurately placed in the designated position, maintaining their integrity during transfer. This device improves upon the outdated manual koji-making process by automating koji pressing and mechanized clamping and pushing, effectively resolving the core contradiction of short production time and large koji demand. It significantly increases koji-making efficiency, saving manpower, resources, and time. Furthermore, it eliminates the hygiene hazards associated with barefoot koji treading, improving hygiene from the source. Simultaneously, it ensures the koji blocks remain intact, creating a more stable fermentation environment for the koji-making microorganisms, promoting better microbial reproduction and metabolism, and ultimately improving the quality of the koji, providing high-quality raw materials for subsequent brewing.

[0014] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0015] like Figure 1 - Figure 5 As shown, a high-efficiency koji-making machine includes a table panel 1, a control panel fixedly installed on one side of the table panel 1, columns 2 fixedly connected around the top of the table panel 1, an upper support plate 3 fixedly connected to the top of the columns 2, a material box 4 fixedly connected to the top of the table panel 1, and a koji-forming component and a clamping and pushing component are provided on the table panel 1.

[0016] The control panel is used to control the operation of the entire device. The platform 1 serves as a basic support component, providing a stable working platform for the entire equipment. The columns 2 are evenly distributed around the top of the platform 1, serving to support the upper support plate 3 and ensuring that the upper support plate 3 can be stably positioned at a certain height above the platform 1. The upper support plate 3 provides support for the pressing and pressing components and the clamping and pushing components. The material box 4 is installed on the top of the platform 1 to hold the raw materials to be processed, facilitating subsequent pressing and pressing into blocks. The pressing and block-forming component allows for precise control of the control panel to apply appropriate pressure to the raw materials in the material box 4, pressing them into blocks of a specific shape and size. During the rising process, the pressed blocks can be pushed upwards for easy retrieval, thus efficiently producing a large number of blocks in a short time. This effectively improves the hygiene issues of the original manual barefoot treading process, saves koji-making time, allows the koji-making bacteria to ferment better, and further enhances the quality of the wine. The clamping and pushing component works in conjunction with the pressing and forming component. After the pressing and forming component presses the raw material into blocks, the clamping and pushing component can stably clamp the blocks from both sides and push them from the top of the material box 4 to the pick-up point. During the pushing process, the clamping and pushing component, with its precise force control and stable clamping performance, ensures that the blocks will not be damaged or deformed due to bottom shaking or uneven force, ensuring that each block can reach the pick-up point completely and accurately. At the same time, the clamping and pushing component also has an automatic reset function. After completing one block pushing task, it can quickly return to the initial position and wait for the next work instruction, further improving the automation and work efficiency of the entire koji making process. This device can press 60 to 100 koji blocks per hour, ensuring that the same batch of koji can be quickly concentrated and put into the fermentation room for fermentation. This is equivalent to the work efficiency of about 200 people, effectively improving the hygiene of the traditional manual koji-making process, and also saving manpower and material resources.

[0017] like Figure 2 and Figure 3 As shown, the compression molding assembly includes a moving screw 5 slidably connected to the top of the upper support plate 3. A connecting plate 6 is rotatably connected to the bottom end of the moving screw 5. Two pressure heads 7 are fixedly connected to the center of the bottom end of the connecting plate 6. Guide rods 8 are fixedly connected to both sides of the bottom of the connecting plate 6. The surfaces of the two guide rods 8 are slidably connected to the table panel 1. A travel support plate 9 is fixedly connected to the bottom end of the two guide rods 8 and located at the bottom of the table panel 1. A round hole 10 is opened at the top of the travel support plate 9. A rectangular groove 11 is opened at the top of the table panel 1 and located at the bottom of the inner cavity of the material box 4. Two sliding holes 12 are opened on the rectangular groove 11. First ejector pins 13 are slidably connected to the inner walls of both sliding holes 12. Each first ejector pin... Finished top plates 14 are fixedly installed on the top of 13 and inside the rectangular groove 11. Finished bottom plates 15 are fixedly connected to the bottom of the two first ejector pins 13. Second ejector pins 16 are fixedly connected to the bottom of the finished bottom plate 15, and the surface of the second ejector pins 16 is slidably connected in the round hole 10. The top of the upper support plate 3 is rotatably connected to the first pulley 17. The surface of the moving screw 5 is slidably connected to the inner wall of the first pulley 17. A motor 18 is fixedly installed on one side of the upper support plate 3. A second pulley 19 is fixedly installed at the output end of the motor 18. A conveyor belt 20 is rotatably connected between the first pulley 17 and the second pulley 19. A movable limit component is provided on the stroke support plate 9.

[0018] Specifically, according to the insert rod 22 and the second ejector rod 16 mentioned below, manually pull the insert rod 22 out from the insertion hole at the bottom of the second ejector rod 16, so that the second ejector rod 16 falls down along the round hole 10 on the travel support plate 9. At this time, the finished product top plate 14 overlaps with the rectangular groove 11. Manually fill the material box 4 with the curved material. Drive the motor 18 through the control panel to drive the second pulley 19 to rotate, thereby causing the conveyor belt 20 and the first pulley 17 to rotate clockwise. At the same time, push the moving screw 5, the connecting plate 6 and the pressure head 7 to move downward, so that the pressure head 7 squeezes the curved material. The downward movement of the connecting plate 6 drives the travel support plate 9 to move to the bottom of the second ejector rod 16. The first spring 23 has a rebound force. When the first spring 23 is close to the insertion hole, the insert rod 22 can slide into the insertion hole at the bottom of the second ejector rod 16. At this time, the downward travel limit switch is triggered, the motor 18 is de-energized, and the pressure head 7 stops moving downward, and the pressing is completed. Subsequently, the control panel drives the motor 18 to rotate the second pulley 19 in the opposite direction, which in turn causes the conveyor belt 20 and the first pulley 17 to rotate counterclockwise. At the same time, the moving screw 5 and the pressure head 7 move upward. When the finished product bottom plate 15 overlaps with the table panel 1, the finished product top plate 14 overlaps with the top of the material box 4. The travel support plate 9 triggers the upward travel limit switch, the motor 18 is de-energized, and the upward movement stops. The material discharge is completed. This device improves the efficiency of koji making and changes the outdated process of manually stepping on the koji during traditional winemaking. It effectively solves the contradiction between short koji making time and large demand for koji materials, reduces human resource input, improves the hygiene of the original manual barefoot koji stepping process, and saves koji making time, allowing the koji-making bacteria to ferment better, thereby further improving the quality of the wine.

[0019] like Figure 2 and Figure 3 As shown, the movable limiting component includes rectangular plates 21 fixedly connected to both sides of the top of the travel support plate 9. One side of one of the rectangular plates 21 is inserted with a rod 22. The rod 22 has an I-shaped structure. A first spring 23 is fixedly connected to the side of the rod 22 that is close to the rectangular plate 21, and the first spring 23 is sleeved on the surface of the rod 22. The bottom of the second ejector rod 16 has a hole for use with the rod 22.

[0020] When it is necessary to fill the material box 4, the insert rod 22 needs to be manually pulled out from the insertion hole at the bottom of the second ejector rod 16 and one side of the insert rod 22 abuts against the surface of the second ejector rod 16, so that the second ejector rod 16 moves down along the round hole 10 under the influence of gravity, so that the finished product top plate 14 can fall into the rectangular groove 11 at the bottom of the material box 4, so that the finished product top plate 14 can be stacked with the table panel 1; The rectangular plate 21 limits the movement range of the finished product top plate 14. When the travel support plate 9 moves the rectangular plate 21 to the bottom end of the second ejector pin 16, the insertion rod 22 can be accurately inserted into the insertion hole at the bottom end of the second ejector pin 16 under the action of the rebound force of the first spring 23, ensuring that the finished product bottom plate 15 and the finished product top plate 14 can be raised when rising, thereby moving the pressed curved material block in the material box 4 to the top of the material box 4, which is convenient for subsequent pushing and collection.

[0021] like Figure 4 and Figure 5 As shown, the clamping and pushing assembly includes strip grooves 24 on both sides of the top of the table panel 1. Sliding support plates 25 are slidably connected in both strip grooves 24. U-shaped push plates 26 are fixedly connected to the top of the two sliding support plates 25. Strip holes 27 are opened on both sides of the U-shaped push plates 26. T-shaped rods 28 are slidably connected in each strip hole 27. Rectangular pressure plates 29 are fixedly connected to the opposite sides of the two T-shaped rods 28. A first rack 30 is fixedly connected to the side of each rectangular pressure plate 29 near the T-shaped rod 28. Gears 31 are fixedly connected to both sides of the top of the U-shaped push plate 26, and the top of one side of the gear 31 meshes with one side of the first rack 30. An electric push rod 32 is fixedly installed on the top of the table panel 1. The piston rod of the electric push rod 32 is fixedly connected to a U-shaped toothed push rod 33. The two sides of the inner wall of the U-shaped toothed push rod 33 mesh with the bottom of one side of the gear 31.

[0022] Specifically, after the material is discharged, the pressed and shaped curved block will be at the top of the material box 4. The electric push rod 32 driven by the control panel will drive the U-shaped toothed push rod 33 to move closer to the U-shaped push plate 26. The U-shaped toothed push rod 33 will drive the gear 31 meshing with it to rotate. The rotation of the gear 31 will drive the first rack 30 meshing with it to move. The movement of the first rack 30 will drive the rectangular pressure plates 29 on both sides of the U-shaped push plate 26 to move closer to each other. The rectangular pressure plates 29 will drive the T-shaped rods 28 to slide in the strip hole 27. The two T-shaped rods 28 move relative to each other, thereby clamping the curved block at the top of the material box 4 through the rectangular pressure plates 29. While the rectangular pressure plates 29 are clamping relative to each other, according to the following text, the gear 31 rotates through the bottom The connecting block 34 slides in the second slide groove 36, and the gear 31 rotates the connecting block 34 at the top to slide in the first slide groove 35. Therefore, the gear 31 can drive the U-shaped push plate 26 to approach the rectangular pressure plate 29, and drive the U-shaped push plate 26 through the U-shaped toothed push rod 33, thereby driving the entire clamping and pushing assembly to move, pushing the clamped curved block out from the top of the material box 4, completing the discharge operation of the curved block. When manually picking up the curved block, due to improper force control or careless operation, it is very easy to cause varying degrees of damage to the curved block, affecting its integrity and use effect. Therefore, this device can avoid manual direct contact with the curved block, and use appropriate tools or equipment to handle and place the curved block, ensuring that the curved block remains intact throughout the entire operation. After the koji block is fully pushed out, the drive electric push rod 32 drives the U-shaped toothed push rod 33 to move in the opposite direction. At this time, the U-shaped toothed push rod 33 drives the gear 31 meshing with it to rotate in the opposite direction. The gear 31 rotates in the opposite direction, which drives the first rack 30 meshing with it to move in the opposite direction. The first rack 30 moves in the opposite direction, which in turn drives the rectangular pressure plates 29 on both sides of the U-shaped push plate 26 to move away from each other. The rectangular pressure plates 29 drive the T-shaped rods 28 to slide in the opposite direction in the strip hole 27. The two T-shaped rods 28 move away from each other, thereby releasing the clamping of the koji block. Then, the gear 31 continues to slide in the opposite direction in the second slide groove 36 through the bottom rotating connecting block 34, and the gear 31 slides in the opposite direction in the first slide groove 35 through the top rotating connecting block 34, which drives the U-shaped push plate 26 back to the initial position. The entire device returns to the standby state so as to carry out the next koji making and material discharge operation, reducing the risk of damage to the koji block caused by manual operation and improving the quality and stability of the koji making process.

[0023] like Figure 5 As shown, the top and bottom of the gear 31 are rotatably connected to rotating connecting blocks 34. Each first rack 30 has a first groove 35 on the top side near the gear 31. The top rotating connecting blocks 34 are slidably connected in the first groove 35. The top and sides of the U-shaped push plate 26 have second grooves 36. The bottom rotating connecting blocks 34 are slidably connected in the second groove 36.

[0024] The gear 31 is slidably connected to the first slide groove 35 and the second slide groove 36 through the rotating connecting blocks 34 at the top and bottom, respectively. This not only does not affect the movement of the rectangular pressure plates 29 on both sides, but also ensures that the gear 31 is always engaged with the first slide groove 35. Furthermore, the gear 31 can pull the rectangular pressure plate 29 closer to the inner wall of the U-shaped push plate 26, thereby achieving the clamping and pushing of the curved material block.

[0025] like Figure 4 and Figure 5 As shown, each T-shaped rod 28 has a limiting block 37 slidably connected to the surface away from the rectangular pressure plate 29. Each limiting block 37 has a sliding rod 38 slidably connected to its bottom. Both ends of the sliding rod 38 are fixedly connected to strip rods 39. The bottom of the strip rods 39 is fixedly connected to the top of the table panel 1. One side of one of the strip rods 39 has an inverted L-shaped structure. A second spring 40 is fixedly connected to the side of one of the strip rods 39 that is close to the limiting block 37, and the second spring 40 is sleeved on the surface of the sliding rod 38.

[0026] Specifically, when each T-shaped rod 28 slides on the inner wall of the limiting block 37, it is limited to horizontal movement within the range specified by the limiting block 37, ensuring that the T-shaped rod 28 does not deviate from the predetermined trajectory during sliding and maintains the supporting effect of the rectangular pressure plate 29. Since the bottom of the strip rod 39 is firmly fixed to the top of the table panel 1, this connection method provides a solid and stable support foundation for the entire sliding structure. The tensile effect of the finished top plate 14 effectively prevents the T-shaped rod 28 from exerting a forward pushing force on the rectangular pressure plate 29 and the U-shaped push plate 26.

[0027] The working principle of this utility model is as follows: During the koji-making process, the insert rod 22 is manually pulled out to release the limit on the second ejector rod 16, causing the second ejector rod 16 to fall down along the circular hole 10 of the travel support plate 9. The finished product top plate 14 overlaps with the rectangular groove 11. After filling the material box 4 with koji material, the drive motor 18 drives the second pulley 19 to rotate. Through the transmission belt 20, the first pulley 17 rotates clockwise, pushing the pressure head 7 down to squeeze the koji material. When the travel support plate 9 moves to the bottom of the second ejector rod 16, the insert rod 22 is inserted into the insertion hole of the second ejector rod 16 under the action of the first spring 23 and triggers the downward limit switch. The motor 18 is de-energized to complete the koji pressing. Subsequently, the motor 18 drives in the reverse direction to make the first pulley 17 rotate counterclockwise, driving the pressure head 7 up. When the finished product bottom plate 14 is filled with koji material, the first pulley 19 rotates counterclockwise, causing the pressure head 7 to move up. 5 overlaps with the tabletop 1, the finished product top plate 14 is flush with the top of the material box 4 and triggers the upward limit switch, the motor 18 is de-energized to complete the material discharge; after discharge, the electric push rod 32 drives the U-shaped toothed push rod 33 to move, the U-shaped toothed push rod 33 meshes with the transmission gear 31, thereby causing the first rack 30 to drive the T-shaped rod 28 and the rectangular pressure plate 29 to slide relative to each other in the strip hole 27 to clamp the koji block, at the same time the gear 31 slides in the first slide groove 35 and the second slide groove 36 with the help of the rotating connecting block 34, driving the U-shaped push plate 26 and the rectangular pressure plate 29 to push the koji block to the block picking position. After the push is completed, the electric push rod 32 drives in the reverse direction, causing the rectangular pressure plate 29 to release the koji block and drive the U-shaped push plate 26 to reset, waiting for the next koji making cycle, thereby completing the automatic pressing, discharge and conveying of koji.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
