Description

Technical Field

[0001] This invention relates to the field of feed fermentation equipment technology, and in particular to a fermented feed spray-type uniform mixing device. Background Technology

[0002] Jasmine flower residue, a major byproduct of jasmine tea processing, is rich in nutrients such as protein, amino acids, and cellulose, possessing high value for feed development. Through microbial fermentation, its crude fiber can be effectively degraded, palatability improved, and protein content increased, transforming it into a high-quality fermented feed ingredient. In the fermentation process, the uniformity of mixing the bacterial solution and the material directly affects fermentation efficiency and product quality; therefore, efficient and stable mixing equipment is one of the key elements in realizing the resource utilization of jasmine flower residue.

[0003] Currently, in the field of biomass feed fermentation, the commonly used methods for mixing bacteria are batch mixing or simple spray mixing. Batch mixing typically involves placing a fixed amount of solid material and liquid inoculant into the same container and mixing them using mechanical agitators. This method has significant drawbacks: Firstly, the inoculant solution is usually added from the top or side of the material, making it difficult for the solution to penetrate deep into the material pile during mixing. This results in a large difference in inoculum concentration between the surface and the interior, leading to poor mixing uniformity and a tendency for localized fermentation delays or even spoilage. Secondly, jasmine flower residue has a high fiber content and is prone to absorbing water and clumping. During mixing, it easily clumps together due to moisture, and conventional mixing structures cannot effectively break it up, further exacerbating the uneven distribution of the inoculant solution. It also easily forms bridging and blockages at container joints or in the material guide channels, affecting the stability of continuous equipment operation.

[0004] Simple spray mixing involves setting up fixed spray pipes along the material conveying path to spray and inoculate the material. While this method allows for a degree of continuous operation, the spray range and depth are limited. The bacterial solution only adheres to the shallow surface of the material, making it difficult for the inoculum to reach the interior, thus failing to achieve deep and uniform inoculation. Furthermore, fixed spraying lacks coordination with stirring, making it difficult to agitate and break up the material during transport. The enclosed spaces within clumps are difficult to be infiltrated by the bacterial solution, limiting the consistency and efficiency of the fermentation process.

[0005] More notably, fibrous materials such as jasmine flower residue exhibit significant variations in their degree of fragmentation, moisture content, and physical state across different batches or from different sources. Existing equipment is mostly of a fixed structure, making it difficult to flexibly adjust operating parameters and process flows, and unable to add or remove processing steps or adjust mixing intensity based on fluctuations in material properties. This lack of adaptability results in significant fluctuations in the quality of mixed microbial culture and processing efficiency when the same equipment is used with materials of different properties, failing to meet the needs of large-scale, diversified production.

[0006] Furthermore, during the mixed culture process, an excessive amount of bacterial solution is often applied to ensure adequate inoculation. Existing equipment often does not consider the recovery and reuse of this excess bacterial solution; the excess solution often enters subsequent processes with the materials or is directly lost, resulting in waste of the bacterial agent, increased production costs, and potential for excessively high local humidity due to liquid accumulation, affecting the precise control of fermentation conditions. For open or semi-closed equipment, the sealing between rotating parts and the liquid supply channel is also a technical challenge. If the seal is unreliable, the continuity of the bacterial solution supply and the operational stability of the rotating parts are affected, leading not only to bacterial solution leakage but also to equipment wear and malfunctions.

[0007] In summary, existing feed fermentation mixing devices still have many shortcomings in terms of deep and uniform spraying of bacterial solution, material dispersion and smooth feeding, adaptability to materials in multiple states, recovery and utilization of excess bacterial solution, and reliability of rotating liquid supply sealing. Therefore, there is an urgent need to develop a fermentation feed spraying and uniform mixing device that can achieve integrated operation of bacterial spraying and mixing, enhance material adaptability, promote deep and uniform adsorption of bacterial solution, and effectively recover excess bacterial solution, in order to meet the actual needs of efficient fermentation production of fibrous materials such as jasmine flower residue.

The hollow stirring columns are all inclined downwards, and one end of the hollow stirring column is connected to the transmission guide cylinder. A plurality of bacterial liquid nozzles are arranged at equal intervals on the upper end of the hollow stirring column.

[0018] As a further embodiment of the present invention: a spiral guide plate is provided on the outside of the conveying guide cylinder and the transmission guide cylinder inside the connecting guide cylinder, and a number of annular protrusions are provided vertically and at equal intervals on the inner walls of the conveying guide cylinder and the connecting guide cylinder.

[0019] As a further embodiment of the present invention: a drive guide cylinder is provided at the middle position of the feed cylinder, a limit transmission ring is provided on the outside of the drive guide cylinder, a limit transmission sleeve is provided in conjunction with the limit transmission ring, a transmission gear ring is provided at the middle position of the limit transmission ring, and a plurality of drive gears are provided at equal angles inside the limit transmission sleeve, all of which mesh with the transmission gear ring.

[0020] As a further embodiment of the present invention: a sealing rotating ring is provided at the upper end of the driving guide cylinder, a sealing rotating sleeve is provided at the upper end of the limiting transmission sleeve in conjunction with the sealing rotating ring, a connecting flange is provided at the upper end of the sealing rotating sleeve, and a plurality of guide rods are provided at equal angles on the outer side of the limiting transmission sleeve, with the outer ends of the guide rods connected to the inner wall of the feeding cylinder.

[0021] As a further embodiment of the present invention: a spiral guide plate is provided on the outside of the transmission guide cylinder in the conveying guide cylinder and the seepage guide cylinder, and a sealing rotating cylinder is provided at the lower end of the transmission guide cylinder in the seepage guide cylinder. A positioning rotating ring is provided at the outer end of both the sealing rotating cylinder and the transmission guide cylinder. A positioning rotating sleeve is provided in conjunction with the positioning rotating ring. A plurality of guide plates are provided at equal angles on the outer side of the positioning rotating sleeve. The positioning rotating ring and the positioning rotating sleeve in the variable diameter stirring cylinder are located on the transmission guide cylinder above the hollow stirring column. The outer end of the guide plate in the variable diameter stirring cylinder is connected to the inner wall.

[0022] As a further embodiment of the present invention: the lower ends of the drive guide cylinder and the transmission guide cylinder are provided with a plurality of positioning and mounting posts at equal angles, and the end faces of the drive guide cylinder and the transmission guide cylinder on both the inner and outer sides of the positioning and mounting posts are provided with extrusion sealing rings.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] Modular design with strong adaptability: By connecting multiple sets of spraying, mixing and guiding mechanisms in series, and using detachable connection structures such as connecting rings, combined rings and positioning columns, the number of processing groups can be flexibly increased or decreased according to the degree of fragmentation and dryness of jasmine flower residue, ensuring the quality and efficiency of mixed bacteria under different material conditions.

[0025] The integrated spraying and mixing process significantly improves the spraying depth and uniformity: The hollow mixing column inside the variable diameter mixing drum serves both as a mixer and as a channel for the bacterial solution. Its downward-sloping arrangement and upward-spraying bacterial solution nozzles ensure that the material is mixed and dispersed during rotation, while the bacterial solution pushes the material upward from bottom to top, achieving deep spraying. The tilting direction also guides the material downward smoothly, preventing it from clumping together and getting stuck, thus ensuring smooth material flow.

[0026] The combination of extrusion feeding and micro-slit diffusion results in better mixing: After spraying, the material is conveyed under compression in the conveying cylinder and connecting cylinder through the spiral guide plate, which reduces the gap between the materials and allows the bacterial solution to diffuse rapidly in the micro-slits. After multiple feedings, the bacterial solution is more easily adsorbed into the material. The multiple annular protrusions vertically set on the cylinder wall cause the material to repeatedly contract and fall, further enhancing the uniformity of mixing between the bacterial solution and the material without damaging the structure of the jasmine flower residue.

[0027] Automatic bacterial liquid recycling saves costs: The bottom is equipped with a seepage guide cylinder and an open annular collection cylinder with extrusion holes, which can collect the excess bacterial liquid that is squeezed out and discharge it to the recycling equipment in a timely manner through the drain pipe and solenoid valve, so as to realize the recycling of bacterial liquid and reduce bacterial liquid waste and environmental pollution.

[0028] The reliable rotation and sealing structure ensures continuous and stable operation: the drive guide cylinder, transmission guide cylinder, and sealing rotation cylinder are connected as a whole through positioning mounting columns, extrusion sealing rings, and sealing grooves. The drive gear drives the transmission gear ring to achieve synchronous rotation, which, together with the positioning rotation ring, positioning rotation sleeve, and guide plate, ensures rotational stability. The sealing rotation ring and sealing rotation sleeve and other structures keep the bacterial liquid supply channel sealed during rotation, achieving continuous supply of bacterial liquid, stable operation of the device, and high production efficiency.

[0048] The open annular liquid collecting cylinder 7 has several bent support feet 8 arranged at equal angles on its outer side.

[0049] Jasmine flower residue is introduced into the device through the feed cylinder 1. The jasmine flower residue falls downward and passes through multiple sets of spraying, stirring and guiding mechanisms connected in series. It is simultaneously sprayed and stirred in the variable diameter stirring cylinder 4. Then it falls to the bottom of the variable diameter stirring cylinder 4 and passes through the conveying guide cylinder 5 and the connecting guide cylinder 6 into the next variable diameter stirring cylinder 4. The above operation is repeated until it is discharged from the seepage guide cylinder 20 to the external collection device. After the jasmine flower residue is sprayed and stirred, it enters the seepage guide cylinder 20. The excess bacterial liquid in the squeezed jasmine flower residue is discharged from the squeeze seepage hole 36 to the open annular collection cylinder 7. The bacterial liquid collected in the open annular collection cylinder 7 for a period of time is discharged from the discharge pipe 9 through the solenoid valve 10 to the external bacterial liquid recovery device.

[0050] The number of spraying, mixing, and guiding mechanisms can be increased or decreased according to the specific state of the jasmine flower residue, including its degree of fragmentation and moisture content, to ensure the quality and efficiency of the mixed bacteria on the jasmine flower residue.

[0051] Example 2, based on Example 1, please refer to... Figures 1 to 11 In this embodiment of the invention, the lower end of the feed cylinder 1 and the lower end of the connecting guide cylinder 6 are both provided with connecting mounting rings 28. The upper end of the variable diameter stirring cylinder 4 at the edge of the connecting guide hole 33 is provided with a plurality of connecting screw holes 32 at equal angles. The connecting mounting ring 28 is provided with a plurality of connecting mounting holes 29 at equal angles. The connecting mounting holes 29 and the connecting screw holes 32 are directly opposite each other and are fixed by externally provided screws.

[0052] The lower end of the conveying guide cylinder 5 and the upper end of the adjacent connecting guide cylinder 6 are both provided with a combined mounting ring 39 facing each other. The lower end of the conveying guide cylinder 5 and the upper end of the seepage guide cylinder 20 are also provided with a combined mounting ring 39 facing each other. The combined mounting rings 39 facing each other are provided with mating mounting holes 37 at equal angles. The mating mounting holes 37 facing each other are fixed by externally provided bolts and nuts. A number of sealing rubber rings 38 are provided between the combined mounting rings 39 facing each other.

[0053] The lower ends of the drive guide cylinder 15 and the transmission guide cylinder 16 are provided with a plurality of positioning and mounting posts 30 at equal angles. On the inner and outer sides of the positioning and mounting posts 30, the end faces of the drive guide cylinder 15 and the transmission guide cylinder 16 are provided with compression sealing rings 31. The upper ends of the transmission guide cylinder 16 and the sealing rotating cylinder 11 are provided with positioning and mounting holes 34 in conjunction with the positioning and mounting posts 30. The end faces of the transmission guide cylinder 16 and the sealing rotating cylinder 11 are provided with compression sealing grooves 35 in conjunction with the compression sealing rings 31.

[0054] The corresponding number of spraying, mixing, and guiding mechanisms are installed in series. Specifically, the combined mounting rings 39 on adjacent conveying guide cylinders 5 and connecting guide cylinders 6 are aligned, as are the combined mounting rings 39 on conveying guide cylinders 5 and permeation guide cylinders 20. The mating mounting holes 37 on the aligned combined mounting rings 39 are also aligned. Bolts and nuts are installed on the aligned mating mounting holes 37 to fix the aligned combined mounting rings 39. At this time, the sealing rings 38 between the combined mounting rings 39 achieve a sealing connection under compression. Then, the connecting mounting holes 29 and connecting screw holes 32 between the feed cylinder 1 and the variable diameter mixing cylinder 4, and between the connecting guide cylinder 6 and the variable diameter mixing cylinder 4 are aligned. At this time, the externally set screws are aligned with the connecting mounting holes 29 and screwed into the connecting screw holes 32 to fix the connecting mounting rings 28.

[0055] While the feed cylinder 1, the variable diameter mixing cylinder 4, the conveying guide cylinder 5, the connecting guide cylinder 6, and the seepage guide cylinder 20 are connected and installed, the drive guide cylinder 15, several transmission guide cylinders 16, and the sealing rotating cylinder 11 are connected synchronously. Specifically, the positioning mounting posts 30 between the drive guide cylinder 15 and the transmission guide cylinder 16, between the transmission guide cylinders 16 and the transmission guide cylinder 16, and between the transmission guide cylinder 16 and the sealing rotating cylinder 11 are inserted into the corresponding positioning mounting holes 34. At this time, the extrusion sealing ring 31 is inserted into the extrusion sealing groove 35.

[0056] Example 3, based on Example 2, please refer to... Figures 2 to 11 In this embodiment of the invention, a transmission guide cylinder 16 is vertically arranged in the middle of the variable diameter stirring cylinder 4, the conveying guide cylinder 5 and the connecting guide cylinder 6 connected in sequence.

[0057] A plurality of hollow stirring columns 18 are evenly arranged at equal angles on the outer side of the transmission guide cylinder 16 inside the variable diameter stirring cylinder 4. All hollow stirring columns 18 are inclined downwards, and one end of the hollow stirring column 18 is connected to the transmission guide cylinder 16. A plurality of bacterial liquid nozzles 19 are evenly arranged at the upper end of the hollow stirring column 18.

[0058] Spiral guide plates 17 are provided on the outer side of the conveying guide cylinder 5 and the transmission guide cylinder 16 inside the connecting guide cylinder 6. Several annular protrusions 26 are vertically and equally spaced on the inner wall of both the conveying guide cylinder 5 and the connecting guide cylinder 6.

[0059] A drive guide cylinder 15 is provided at the middle position of the feed cylinder 1. A limit transmission ring 21 is provided on the outside of the drive guide cylinder 15. A limit transmission sleeve 14 is provided in conjunction with the limit transmission ring 21. A transmission gear ring 22 is provided at the middle position of the limit transmission ring 21. Several drive gears 27 are provided at equal angles inside the limit transmission sleeve 14. All drive gears 27 mesh with the transmission gear ring 22.

[0060] The upper end of the drive guide cylinder 15 is provided with a sealing rotating ring 24, the upper end of the limiting transmission sleeve 14 is provided with a sealing rotating sleeve 2 in conjunction with the sealing rotating ring 24, the upper end of the sealing rotating sleeve 2 is provided with a connecting flange 3, and a plurality of guide rods 25 are provided at equal angles on the outer side of the limiting transmission sleeve 14, and the outer end of the guide rods 25 is connected to the inner wall of the feed cylinder 1.

[0061] Spiral guide plates 17 are provided on the outer side of the transmission guide cylinder 16 inside the conveying guide cylinder 5 and the seepage guide cylinder 20. A sealing rotating cylinder 11 is provided at the lower end of the transmission guide cylinder 16 inside the seepage guide cylinder 20. A positioning rotating ring 23 is provided at the outer end of both the sealing rotating cylinder 11 and the transmission guide cylinder 16. A positioning rotating sleeve 12 is provided in conjunction with the positioning rotating ring 23. A number of guide plates 13 are provided at equal angles on the outer side of the positioning rotating sleeve 12. The positioning rotating ring 23 and the positioning rotating sleeve 12 inside the variable diameter stirring cylinder 4 are located on the transmission guide cylinder 16 above the hollow stirring column 18. The outer end of the guide plate 13 inside the variable diameter stirring cylinder 4 is connected to the inner wall. The outer end of the guide plate 13 outside the sealing rotating cylinder 11 is connected to the cylinder wall of the open annular liquid collecting cylinder 7.

[0062] When multiple sets of spraying, stirring, and guiding mechanisms are installed, the drive guide cylinder 15, several transmission guide cylinders 16, and the sealing rotating cylinder 11 are synchronously connected. At this time, the drive gear 27 meshes with the transmission gear ring 22, causing the limiting transmission ring 21 to rotate within the limiting transmission sleeve 14, which drives the drive guide cylinder 15, transmission guide cylinder 16, and sealing rotating cylinder 11 to rotate synchronously. With the cooperation of the positioning rotating ring 23 and the positioning rotating sleeve 12, the transmission guide cylinder 16 and the sealing rotating cylinder 11 are ensured to rotate stably. At the same time, the sealing rotating ring 24 rotates in cooperation with the sealing rotating sleeve 2, ensuring that the bacterial liquid supply equipment connected to the connecting flange 3 can continuously input bacterial liquid during the rotation process.

[0063] While the transmission guide cylinder 16 rotates, the jasmine flower residue falling from the feed cylinder 1 or each connecting guide cylinder 6 is stirred and dispersed. At the same time, the bacterial liquid is sprayed from bottom to top through each hollow stirring column 18 and the bacterial liquid nozzle 19 on it, pushing the stirred and dispersed jasmine flower residue upward. With the stirring, the spraying depth and uniformity of the bacterial liquid in a single spray can be significantly improved. Since the hollow stirring column 18 is set to tilt downward, the bacterial liquid sprayed upward with the bacterial liquid nozzle 19 can ensure that the jasmine flower residue can be smoothly guided downward during the stirring process, avoiding clumping and getting stuck at the connection.

[0064] While the transmission guide cylinder 16 rotates, the spiral guide plate 17 also rotates synchronously, guiding the sprayed and stirred jasmine flower residue into the conveying guide cylinder 5 and the connecting guide cylinder 6 before exporting it. During this process, the jasmine flower residue is under compression, the gaps become smaller, and the bacterial solution diffuses more easily in the micro gaps, quickly spreading into the gaps between the jasmine flower residue. After multiple feedings by the spiral guide plate 17, the bacterial solution can be absorbed into the interior of the jasmine flower residue. Since the inner walls of the conveying guide cylinder 5 and the connecting guide cylinder 6 are vertically and equally spaced with several annular protrusions 26, the jasmine flower residue and bacterial solution are guided in a continuous contraction, further improving the mixing degree and uniformity of the jasmine flower residue and bacterial solution without damaging the jasmine flower residue.
