Description

Technical Field

[0001] This utility model relates to the field of miso production technology, specifically to a fine screening device for raw materials used in miso production. Background Technology

[0002] As a traditional fermented condiment, the quality of miso is closely related to the selection of raw materials. In particular, the purity and particle size uniformity of the salt directly affect the fermentation process and the flavor of the final product. In miso production, salt not only plays a flavoring role but also inhibits the growth of unwanted bacteria and maintains the osmotic pressure balance of the fermentation system. Its quality affects the fermentation cycle, taste, color, and shelf life of miso. Therefore, precise selection of salt is a crucial step in ensuring the quality of miso.

[0003] Currently, most miso producers still use vibrating machines to screen salt raw materials. Although these machines can perform basic screening, the screening effect is poor, and they lack the ability to effectively separate impurities. Furthermore, they cannot control the speed and quantity of salt raw materials within the screening frame, and excessive input will affect the screening effect.

[0004] According to the description in the patent announcement (CN214766854U) of a salt screening device for miso production, the salt screening device for miso production includes a "conveying device, a vibration device" and the like to perform the screening work.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This salt screening device for miso production uses a conveyor and a vibrating device to perform the screening work. In use, the device uses a vibrating motor and a spring to drive the screen frame to vibrate and perform the screening work. However, there is no protective structure on the top of the screen frame, which causes raw materials to splash during screening. Furthermore, it is impossible to control the amount and speed of raw materials entering the screen frame. If the raw materials are fed manually, it is impossible to ensure that the amount fed each time is consistent. If too much raw material is fed, it will affect the screening effect. Therefore, this device needs to be improved. Utility Model Content

[0010] Preferably, the rotating rod is rotatably connected inside the storage cylinder, the first hydraulic cylinder is fixedly connected to the right side of the support frame, and a guide rod is fixedly connected to the right side of the baffle. The guide rod is slidably connected inside the support frame to facilitate the stability of the baffle movement.

[0011] Preferably, the mounting base is fixedly connected to the rear side of the base, and the second servo motor is fixedly connected to the inner side of the mounting base, so as to facilitate the operation of the rotating shaft by the second servo motor.

[0012] Preferably, the bottom of the sealing ring is in contact with the top of the base, the limiting shaft passes through the inside of the base, the collection frame is located at the bottom of the screening frame, and the screening frame is located at the bottom of the conveying pipe, so that the gap between the top of the base and the bottom of the screening frame can be sealed under the action of the sealing ring, ensuring that the raw materials can smoothly enter the collection frame.

[0013] Preferably, the load-bearing frame is provided in two sets, which are symmetrically distributed on the left and right sides of the storage cylinder. The fixed frame has a limiting groove inside, and the screening frame is rotatably connected to the limiting groove, so as to ensure the stability of the screening frame through the limiting groove.

[0014] Preferably, the protective mechanism includes a second hydraulic cylinder, which is fixedly connected to the right side of the support frame. A protective cover is fixedly connected to the left side of the second hydraulic cylinder. The protective cover is slidably connected to the top of the screening frame.

[0015] Preferably, the bottom of the protective cover is in contact with the top of the screening frame, and the top of the protective cover is slidably connected to the periphery of the conveying pipe. Two sets of the second hydraulic cylinder, slide rod and protective cover are provided and symmetrically distributed on the left and right sides of the conveying pipe, so as to protect and seal the gap between the bottom of the conveying pipe and the top of the screening frame through the protective cover.

[0016] Compared with the prior art, this utility model provides a fine screening device for raw materials in miso production, which has the following beneficial effects:

[0017] 1. This fine screening device for raw materials used in miso production, through its screening mechanism, firstly feeds the salt raw material into a storage cylinder when screening is required. A first servo motor at the top of the storage cylinder drives a rotating rod and a stirring rod to rotate, thoroughly stirring the salt raw material and preventing clumping. This ensures the salt raw material is loose and uniform before entering the screening frame, guaranteeing the accuracy of subsequent screening. The design of the conveying pipe and baffle, in conjunction with a first hydraulic cylinder, allows for precise control of the distance the baffle moves within the conveying pipe by adjusting the range of motion of the first hydraulic cylinder, thus precisely controlling the amount of salt raw material conveyed. With its high conveying speed, the system enables quantitative delivery of salt raw materials, preventing the impact of excessive or insufficient delivery on screening efficiency and production rhythm. The continuous and stable conveying process greatly improves the overall efficiency of salt raw material screening in miso production. After stirring, the salt raw materials are conveyed to the screening frame through the conveying pipe. The screening frame rotates under the drive of the sprocket, chain, and second servo motor, enabling comprehensive and multi-angle screening of the salt raw materials. Compared with the traditional static screening method, it can effectively avoid screening dead corners caused by salt particle accumulation, remove impurities, and provide pure salt raw materials for high-quality miso production.

[0018] 2. This fine screening device for miso production raw materials, through its protective mechanism, allows the protective cover to slide and cover the top of the screening frame under the drive of the second hydraulic cylinder when the salt raw material for miso production is conveyed through the conveying pipe and enters the screening frame for screening. This protects and seals the gap between the bottom of the conveying pipe and the top of the screening frame, further enhancing the device's sealing performance. This not only prevents external dust and debris from entering the screening frame and contaminating the salt raw material, but also reduces excessive contact between the salt raw material and air during the screening process, preventing the salt raw material from absorbing moisture from the air and clumping. This keeps the salt raw material pure and dry, providing stable quality salt raw materials for miso production. Attached Figure Description

[0029] This utility model provides the following technical solution:

[0030] Example 1

[0031] Please see Figure 1-6 This utility model provides a technical solution: a fine screening device for raw materials in miso production, including a base 1, a screening mechanism 2 on the top of the base 1, a protective mechanism 3 on the inner side of the screening mechanism 2, a collection frame 4 slidably connected inside the base 1, and a limit shaft 5 threadedly connected inside the collection frame 4.

[0032] The screening mechanism 2 includes a support frame 21, which is fixedly connected to the top of the base 1. A storage cylinder 22 is fixedly connected to the inner side of the support frame 21. A first servo motor 23 is fixedly connected to the top of the storage cylinder 22. A rotating rod 25 is fixedly connected to the bottom of the first servo motor 23. A stirring rod 26 is fixedly connected to the outer periphery of the rotating rod 25. A conveying pipe 27 is fixedly connected to the bottom of the storage cylinder 22. A baffle 28 is slidably connected inside the conveying pipe 27. A first hydraulic cylinder 291 is fixedly connected to the right side of the baffle 28. A fixed frame 24 is fixedly connected to the inner side of the frame 21. A screening frame 292 is rotatably connected to the inner side of the fixed frame 24. A chain 293 is engaged with the outer side of the screening frame 292. A sprocket 294 is engaged with the inner side of the chain 293. A rotating shaft 295 is fixedly connected inside the sprocket 294. A mounting base 296 is rotatably connected to the outer side of the rotating shaft 295. A second servo motor 297 is fixedly connected to the bottom of the rotating shaft 295. A sealing ring 298 is fixedly connected to the bottom of the screening frame 292. The sealing ring 298 is located on the top of the base 1.

[0033] The rotating rod 25 is rotatably connected to the inside of the storage cylinder 22. The first hydraulic cylinder 291 is fixedly connected to the right side of the support frame 21. The guide rod 29 is fixedly connected to the right side of the baffle 28. The guide rod 29 is slidably connected to the inside of the support frame 21, so as to ensure the stability of the movement of the baffle 28 through the guide rod 29.

[0034] Mounting base 296 is fixedly connected to the rear side of base 1, and second servo motor 297 is fixedly connected to the inside of mounting base 296, so that the rotating shaft 295 can be driven by second servo motor 297.

[0035] The bottom of the sealing ring 298 is in contact with the top of the base 1, the limiting shaft 5 passes through the inside of the base 1, the collection frame 4 is located at the bottom of the screening frame 292, and the screening frame 292 is located at the bottom of the conveying pipe 27, so that the gap between the top of the base 1 and the bottom of the screening frame 292 can be sealed under the action of the sealing ring 298, ensuring that the raw material can smoothly enter the collection frame 4.

[0036] Two sets of load-bearing frames 21 are provided, and the two sets of load-bearing frames 21 are symmetrically distributed on the left and right sides of the storage cylinder 22. The fixed frame 24 has a limit groove inside, and the screening frame 292 is rotatably connected in the limit groove, so as to ensure the stability of the screening frame 292 through the limit groove.

[0037] Example 2

[0038] Please see Figure 1-6Furthermore, based on Embodiment 1, the protective mechanism 3 includes a second hydraulic cylinder 31, which is fixedly connected to the right side of the load-bearing frame 21. A protective cover 33 is fixedly connected to the left side of the second hydraulic cylinder 31. The protective cover 33 is slidably connected to the top of the screening frame 292. A sliding rod 32 is fixedly connected to the right side of the protective cover 33. The sliding rod 32 is slidably connected to the inside of the load-bearing frame 21.

[0039] The bottom of the protective cover 33 is in contact with the top of the screening frame 292. The top of the protective cover 33 is slidably connected to the periphery of the conveying pipe 27. Two sets of the second hydraulic cylinder 31, slide rod 32 and protective cover 33 are provided and symmetrically distributed on the left and right sides of the conveying pipe 27, so as to protect and seal the gap between the bottom of the conveying pipe 27 and the top of the screening frame 292 through the protective cover 33.

[0040] In actual operation, when this device is used and the salt raw material for miso production needs to be screened, the collection frame 4 is first slidably connected to the inside of the base 1 and fixed by the limiting shaft 5. At the same time, the second hydraulic cylinder 31 drives the protective cover 33 to move, and the protective cover 33 drives the slide rod 32 to slide inside the load-bearing frame 21. When the raw material enters the screening frame 292 for screening, the protective cover 33 can slide to cover the top of the screening frame 292 under the drive of the second hydraulic cylinder 31, and protect and seal the gap between the bottom of the conveying pipe 27 and the top of the screening frame 292, further enhancing the sealing performance of the device. This not only prevents external dust and debris from entering the screening frame 292 and contaminating the salt raw material, but also reduces the excessive contact between the salt raw material and the air during the screening process, preventing the salt raw material from becoming damp and clumping due to absorbing moisture from the air.

[0041] At this point, the salt raw material can be fed into the top of the storage cylinder 22. The first servo motor 23 at the top of the storage cylinder 22 drives the rotating rod 25 and the stirring rod 26 to rotate, which can fully stir the salt raw material, prevent the salt particles from clumping, and make the salt raw material in a loose and uniform state before entering the screening frame 292, ensuring the accuracy of subsequent screening. The design of the conveying pipe 27 and the baffle 28 is coordinated with the first hydraulic cylinder 291. The range of movement of the first hydraulic cylinder 291 can control the distance that the baffle 28 moves in the conveying pipe 27, which can accurately control the conveying amount and conveying speed of the salt raw material, realize the quantitative conveying of the salt raw material, and avoid the impact of too much or too little salt raw material on the screening efficiency and production rhythm. The continuous and stable conveying process greatly improves the overall efficiency of salt raw material screening in miso production. By driving the baffle 28 to move through the first hydraulic cylinder 291, and causing the baffle 28 to drive the guide rod 29 to slide inside the load-bearing frame 21, the baffle 28 can be opened, so that the stirred salt raw material is conveyed into the screening frame 292 through the conveying pipe 27.

[0042] The second servo motor 297 drives the sprocket 294 fixedly connected to the outer periphery of the rotating shaft 295 to rotate, so that the sprocket 294 drives the screening frame 292 to rotate inside the fixed frame 24 through the chain 293. This allows for the screening of salt raw materials from all directions and multiple angles. Compared with the traditional static screening method, this can effectively avoid screening dead corners caused by the accumulation of salt particles, remove impurities, and provide pure salt raw materials for the production of high-quality miso. The screened salt raw materials are transported to the collection frame 4 through the bottom of the screening frame 292 for collection. Impurities remain in the screening frame 292. When it is necessary to clean the impurities, the protective cover 33 can be moved away from the top of the screening frame 292 by the action of the second hydraulic cylinder 31.

[0043] The sealing ring 298 at the bottom of the screening frame 292 is in close contact with the top of the base 1, which can effectively prevent the salt raw material powder from overflowing during the screening process, thus avoiding raw material waste and pollution of the production environment.

[0044] In use, the first hydraulic cylinder 291, two sets of second hydraulic cylinders 31, the first servo motor 23 and the second servo motor 297 can be connected to the same PLC control system to ensure the coordinated operation of the equipment. The PLC control system is existing technology, and those skilled in the art are well aware of the specific operating steps and methods of this system. The power supply of these devices is also existing technology, and will not be described in detail in this case.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
