Description

Technical Field

[0001] This utility model belongs to the field of liquor brewing technology, specifically relating to a liquor mash dispersing machine. Background Technology

[0002] The vast majority of China's twelve major aroma types of baijiu (Chinese liquor) employ solid-state fermentation, a process involving solid-state gelatinization, saccharification, fermentation, and distillation. The mash (or fermented mash) refers to the fermented material awaiting addition of other ingredients and distillation. After fermentation, the mash needs to be distilled in a still. For this process, the mash should be loose, evenly spread, and gently distributed. However, fermented mash is prone to clumping, especially in sauce-aroma baijiu which uses glutinous sorghum, a highly viscous material that tends to clump together after repeated distillations. Therefore, before distillation, the mash needs to be loosened and have rice husks added to improve its texture and facilitate distillation, thereby increasing distillation efficiency and yield.

[0003] Currently, the traditional method for dispersing fermented mash is manual. This involves spreading the mash out, using a rake to break it up, adding rice bran, and repeatedly stirring until the mash and bran are evenly mixed before steaming. This method is labor-intensive, and the dispersing and mixing of the mash and bran are uneven, resulting in low distillation efficiency. To address this, existing technologies offer several mash dispersing machines to reduce labor intensity. A common type uses a stirring rod to directly stir and disperse the mash before discharging. However, because many types of fermented mash are highly viscous, especially those used in sauce-flavored baijiu, such machines struggle to guarantee effective dispersing and uniform mixing of the bran. While using a sharper stirring structure, such as the blade-type stirring structure in utility model patent CN219273235U, can improve dispersing, it can damage the surface structure of the mash, affecting its condition and ultimately impacting the final distillation yield. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a mash dispersing machine that can break up mash during the conveying process, and simultaneously add and stir rice bran during the conveying and dispersing process, with good mash dispersing effect and high uniformity of mixing with rice bran.

[0005] This utility model includes a conveying mechanism, a feeding mechanism, a dispersing mechanism, and a rice husk adding mechanism. The feeding mechanism is located above the conveying mechanism and at the beginning of the conveying direction. There are three dispersing mechanisms, which are spaced apart above the conveying mechanism along the conveying direction. Each dispersing mechanism includes a rotating rod and several sets of toothed rods. The rotating rod is parallel to the surface of the conveying mechanism, and its axial direction is along the width of the conveying mechanism. The sets of toothed rods are spaced apart circumferentially on the side of the rotating rod. Each set of toothed rods includes several toothed rods, which are spaced apart along the axial direction of the rotating rod. The spacing between the toothed rods in a single dispersing mechanism along the axial direction of the rotating rod is the same. Along the conveying direction of the conveying mechanism, the spacing between the toothed rods in the three dispersing mechanisms along the axial direction of the rotating rod decreases. The rice husk adding mechanism is located above the conveying mechanism and between the dispersing mechanism near the feeding mechanism and the middle dispersing mechanism.

[0006] Furthermore, it also includes a frame, which is located below the conveying mechanism and has casters with brakes at the bottom.

[0007] Furthermore, the conveying mechanism is provided with handrails on its sides.

[0008] Furthermore, it also includes a scraper, which is disposed above the conveying mechanism and between the husk adding mechanism and the central dispersing mechanism, with the bottom of the scraper spaced apart from the surface of the conveying mechanism to limit the conveying thickness of the mash.

[0009] Furthermore, it also includes a discharge mechanism, which includes a discharge cylinder. The discharge cylinder is located at the end of the conveying direction of the conveying mechanism and is positioned downwards. The mash after being broken up and mixed with chaff enters the discharge cylinder along the end of the conveying mechanism and falls down along the discharge cylinder.

[0010] Furthermore, the discharge mechanism also includes a rotating rod II and several gear sets II. The rotating rod II is rotatably disposed inside the discharge cylinder, and the axial direction of the rotating rod II is arranged along the width direction inside the discharge cylinder. Several gear sets II are circumferentially spaced on the side of the rotating rod II. Each gear set II includes several gears II, and the several gears II are spaced apart along the axial direction of the rotating rod II.

[0011] Furthermore, side baffles are provided on both sides of the surface of the conveying mechanism.

[0012] Furthermore, the conveying mechanism is inclined, with the height of one end of the conveying mechanism being lower than the height of the other end, and the surface of the conveying mechanism is provided with a friction-enhancing structure.

[0013] Furthermore, the feeding mechanism is a feeding hopper, with the bottom of the feeding hopper facing the surface of the conveying mechanism. The bottom of the feeding hopper is spaced apart from the surface of the conveying mechanism on the side near the dispersing mechanism to limit the conveying thickness of the mash. A rear baffle is provided on the bottom of the feeding hopper away from the dispersing mechanism.

[0014] Furthermore, the rice husk adding mechanism is a rice husk adding hopper, the bottom of which faces the surface of the conveying mechanism, and the bottom of the rice husk adding hopper is equipped with a sensing module and a rotatable discharge baffle.

[0015] The beneficial effects of this invention are that it can break up the mash during the conveying process, and simultaneously add and stir the bran husks during conveying and breaking up, thereby improving operational efficiency and reducing manual labor intensity. Because three breaking up mechanisms with progressively decreasing tooth spacing are installed in the conveying direction, the mash can be broken up step by step, gradually dispersing the more viscous mash, improving the breaking up effect, ensuring the looseness of the broken-up mash, and not damaging the surface state of the mash.

[0016] Because the husk addition mechanism is located between the dispersing mechanism near the feeding mechanism and the middle dispersing mechanism, the mash is initially dispersed before the husk is added. The mash with added husk is then dispersed a second time by the middle dispersing mechanism, which simultaneously mixes the mash with the husk. Since the mash has been initially dispersed before mixing with the husk, the mash already has a certain degree of looseness when the husk is mixed with the mash, resulting in better mixing and more uniformity. The dispersing mechanism, located away from the feeding mechanism, further disperses the mash mixed with husk, further improving the looseness of the mash and the uniformity of mixing with the husk. Ultimately, mash with high looseness and high uniformity of husk mixing can be output. Attached Figure Description

[0020] like Figures 1-2As shown, this utility model provides a mash dispersing machine, including a conveying mechanism 1, a feeding mechanism 2, a dispersing mechanism 3, and a husk adding mechanism 4. The conveying direction of the conveying mechanism 1 is the forward direction of the mash when it is conveyed. The feeding mechanism is located above the conveying mechanism 1 and at the beginning of the conveying direction of the conveying mechanism 1, that is, at the end of the conveying mechanism 1. The feeding mechanism 2 is used to feed the mash onto the surface of the conveying mechanism 1. Under the conveying action of the conveying mechanism 1, the mash moves along the surface of the conveying mechanism 1 from the end to the beginning.

[0021] The dispersing mechanism 3 has three parts, all spaced apart above the conveying mechanism 1 along its conveying direction. The three dispersing mechanisms 3 are located in front of the feeding mechanism 2 in the conveying direction of the conveying mechanism 1. The fermented mash passes sequentially through the positions of the three dispersing mechanisms 3 as it is conveyed by the conveying mechanism 1. Each dispersing mechanism 3 includes a rotating rod 31 and several toothed rod sets 32. The rotating rod 31 is parallel to the surface of the conveying mechanism 1, and its axial direction is along the width direction of the conveying mechanism 1, meaning the rotating rod 31 is laterally positioned above the surface of the conveying mechanism 1. Figure 1 As shown, several rack and pinion assemblies 32 are circumferentially spaced on the side of the rotating rod 31. Figure 2 As shown, a single rack assembly 32 includes several racks 321, which are spaced apart along the axial direction of the rotating rod 31. Figure 2 From a visual perspective, several racks 321 located in the same horizontal row form a rack group 32. The racks 321 in a single dispersing mechanism 3 have the same spacing along the axial direction of the rotating rod 31. Along the conveying direction of the conveying mechanism 1, the spacing of the racks 321 in the three dispersing mechanisms 3 decreases along the axial direction of the rotating rod 31.

[0022] by Figure 1 and Figure 2 To explain in detail from a specific perspective. Figure 2 From a visual perspective, the spacing between any two adjacent toothed rods 321 located on the same horizontal row is the axial spacing of several toothed rods 321 along the rotating rod 31. Figure 1From this perspective, the conveying direction of the conveying mechanism 1 is from right to left. Three dispersing mechanisms 3 are arranged sequentially from right to left above the conveying mechanism 1. The spacing between several racks 321 along the axis of the rotating rod 31 in the second dispersing mechanism 3 from the right is smaller than the spacing between several racks 321 along the axis of the rotating rod 31 in the first dispersing mechanism 3 from the right, and the spacing between several racks 321 along the axis of the rotating rod 31 in the third dispersing mechanism 3 from the right is smaller than the spacing between several racks 321 along the axis of the rotating rod 31 in the second dispersing mechanism 3 from the right. For example, the spacing between several racks 321 along the axis of the rotating rod 31 in the first dispersing mechanism 3 from the right is 4-6 cm, the spacing between several racks 321 along the axis of the rotating rod 31 in the second dispersing mechanism 3 from the right is 2-4 cm, and the spacing between several racks 321 along the axis of the rotating rod 31 in the third dispersing mechanism 3 from the right is 1-2 cm.

[0023] The husk adding mechanism 4 is located above the conveying mechanism 1 and between the dispersing mechanism 3 near the feeding mechanism 2 and the middle dispersing mechanism 3, that is, between the first dispersing machine from the right and the second dispersing machine from the right.

[0024] The fermented mash dispersing machine provided by this utility model can disperse the fermented mash during the conveying process, and simultaneously add and stir the bran husks during conveying and dispersing, thereby improving operating efficiency and reducing manual labor intensity. Because three dispersing mechanisms 3 with progressively decreasing toothed rod spacing 321 are set in the conveying direction, the fermented mash can be dispersed step by step, gradually breaking down the more viscous mash, improving the dispersing effect, ensuring the looseness of the dispersed mash, and not damaging the surface state of the fermented mash. Because the husk adding mechanism 4 is located between the dispersing mechanism 3 near the feeding mechanism 2 and the middle dispersing mechanism 3, the mash is initially dispersed before the husk is added. Then, the mash with added husk is dispersed a second time by the middle dispersing mechanism 3, which simultaneously mixes the mash with the husk. Since the mash is initially dispersed before mixing with the husk, the mash already has a certain degree of looseness when the husk is mixed with the mash, resulting in better mixing effect and better uniformity after mixing. The dispersing mechanism 3, which is far from the feeding mechanism 2, disperses the mash mixed with husk again, further improving the looseness of the mash and the uniformity of mixing with the husk. Thus, this invention can ultimately output mash with high looseness and high uniformity of husk mixing.

[0025] In this invention, the dispersing mechanism 3 also includes a rotary drive component, such as a motor, and a rotating rod 31 is connected to the output end of the rotary drive component, which drives the rotation.

[0026] This utility model also includes a frame 6, which is located below the conveying mechanism 1 and is used to support and carry the entire fermented mash dispersing machine. The bottom of the frame 6 is equipped with casters 61 with brakes. Based on this configuration, the entire fermented mash dispersing machine can be moved. By moving the entire fermented mash dispersing machine, fermentation and loading into the still can be carried out simultaneously, thereby improving work efficiency.

[0027] Preferably, the conveying mechanism 1 is provided with a handrail on its side, which makes it easy for the worker to hold it, so that the worker can push the fermentation machine to move as a whole.

[0028] In one embodiment of this invention, the frame 6 extends upward from its side, and the rotating drive component of the feeding mechanism 2, the chaff adding mechanism 4, and one of the three dispersing mechanisms 3 are all disposed on the upwardly extending portion of the frame 6. In other embodiments of this invention, the invention further includes a housing, which covers the conveying mechanism 1, and the bottom of the housing is fixed to the support or the side of the conveying mechanism 1. The rotating drive component of the feeding mechanism 2, the chaff adding mechanism 4, and the three dispersing mechanisms 3 are all disposed on the housing.

[0029] This utility model also includes a scraper, which is disposed above the conveying mechanism 1 and between the husk adding mechanism 4 and the central dispersing mechanism 3. The bottom of the scraper is spaced apart from the surface of the conveying mechanism 1 to limit the conveying thickness of the mash, that is, to limit the amount of mash conveyed to the next dispersing mechanism 3 per unit time. In the aforementioned embodiment in which the frame 6 extends upward from the side, the scraper is fixed on the upwardly extending portion of the frame 6. In the aforementioned embodiment in which a casing is provided, the scraper is fixed on the casing.

[0030] This utility model also includes a discharge mechanism 5, such as Figure 1 As shown, the discharge mechanism 5 includes a discharge cylinder 51, which is located at the end of the conveying mechanism 1 in the conveying direction, i.e., at the end of the conveying mechanism 1 away from the feeding mechanism 2. The discharge cylinder 51 is arranged downwards, and the mash after being broken up and mixed with chaff enters the discharge cylinder 51 along the end of the conveying mechanism 1 and falls down along the discharge cylinder 51. Based on this arrangement, it can be ensured that the mash after being broken up and mixed with chaff falls orderly from the mash breaking machine, reducing the instability of the mash falling, making it easier to use a bucket cart to pick up the mash, and also making it easier for the mash to fall directly towards the still opening.

[0031] In one embodiment of this utility model, the discharge mechanism 5 includes only the discharge cylinder 51. In another embodiment of this utility model, the discharge mechanism 5 further includes a rotating rod 52 and several toothed rod sets 53. The rotating rod 52 is rotatably disposed inside the discharge cylinder 51, and the axial direction of the rotating rod 52 is arranged along the width direction inside the discharge cylinder 51. The several toothed rod sets 53 are circumferentially spaced on the side of the rotating rod 52. Each toothed rod set 53 includes several teeth, and the teeth are spaced along the axial direction of the rotating rod 52. That is, the arrangement of the teeth on the rotating rod 52 is the same as the arrangement of the toothed rod 321 on the rotating rod 31. Based on this arrangement, the mash can be stirred and dispersed to a certain extent during the process of falling along the discharge cylinder 51, ensuring the looseness of the mash during the falling process. The discharge mechanism 5 also includes a second rotary drive component, such as a motor. The second rotating rod 52 is connected to the output end of the second rotary drive component and is driven to rotate by the second rotary drive component. The second rotary drive component is specifically located on the outside of the discharge cylinder 51.

[0032] Side baffles are provided on both sides of the surface of the conveying mechanism 1 to prevent the mash from slipping off the sides of the conveying mechanism 1. Preferably, the height of the side baffles is 15-20cm. In one embodiment of this utility model, such as Figure 1 As shown, the conveying mechanism 1 is inclined, with one end of the conveying mechanism 1 being lower than the other end, which is the end where the discharge mechanism 5 is located. The surface of the conveying mechanism 1 is provided with a friction-enhancing structure, such as a toothed structure, to increase the friction force when conveying the mash and prevent the mash from sliding backward during the conveying process. In other embodiments of this utility model, the conveying mechanism 1 can also be horizontally arranged, depending on the actual needs of the design.

[0033] In this utility model, the conveying mechanism 1 is preferably a plate chain conveyor, which has a large conveying capacity and can bear a large load. The specific structure is existing technology and will not be described in detail here.

[0034] The feeding mechanism 2 is specifically a feeding hopper. The bottom of the feeding hopper is positioned facing the surface of the conveying mechanism 1. The bottom of the feeding hopper is spaced apart from the surface of the conveying mechanism 1 on the side near the dispersing mechanism 3, which is used to allow the mash to pass through and to limit the conveying thickness of the mash. A rear baffle is provided on the bottom of the feeding hopper away from the dispersing mechanism 3 to prevent the mash from sliding backward.

[0035] The rice bran adding mechanism 4 is a rice bran adding hopper, with its bottom facing the surface of the conveying mechanism 1. In one embodiment of this invention, the rice bran adding hopper has a conventional hopper-shaped structure. In another embodiment of this invention, the bottom of the rice bran adding hopper is equipped with a sensing module and a rotatable discharge baffle. The sensing module can be an infrared sensor or other sensing module, which is located at the bottom of the rice bran adding hopper to sense whether there is fermented mash on the area of ​​the surface of the conveying mechanism 1 located at the bottom of the rice bran adding hopper. The discharge baffle is rotatably located at the bottom of the rice bran adding hopper and is driven to rotate by a rotary drive component three located at the bottom or side of the rice bran adding hopper. This rotary drive component three can be a motor or other mechanism. The rotation of the discharge baffle opens or closes the bottom of the rice bran adding hopper. Both the aforementioned sensing module and the rotary drive unit are electrically connected to an external controller. When the sensing module senses that there is mash in the lower area, the rotary drive unit drives the discharge baffle to rotate, opening the bottom of the bran husk adding hopper, allowing the bran husk to fall naturally onto the mash. When the sensing module senses that there is no mash in the lower area, the rotary drive unit drives the discharge baffle to rotate, closing the bottom of the bran husk adding hopper. This process continues until the sensing module senses the presence of mash, at which point the rotary drive unit drives the discharge baffle to rotate and open again.
