Description

Technical Field

[0001] The invention relates to the technical field of material mixing in liquor brewing, and in particular to a method and device for efficiently mixing materials in liquor brewing. Background Art

[0002] In the traditional liquor brewing process, mixing is a crucial link, which directly affects the quality and output of the liquor. The mixing process involves fully mixing the distilled mash with raw materials and auxiliary materials such as cooked grains to ensure the uniformity and efficiency of the fermentation process. Due to the high moisture content of the distilled mash, it is easy to form lumps that are difficult to break up, which directly affects the uniform mixing of the materials. At the same time, the viscosity of the grain increases after gelatinization, and it is easy to form sticky lumps when mixed with the mash. These lumps are not only difficult to effectively disperse through traditional stirring methods, but may also damage the morphology of the mash during the stirring process, thereby affecting the fermentation effect. In addition, the large volume of materials in large-scale production puts higher requirements on the mixing equipment, which requires the equipment to have sufficient stirring force and a wide coverage to achieve fast and uniform mixing.

[0003] The stirring equipment in the prior art often cannot meet these requirements at the same time, resulting in low mixing efficiency and difficulty in adapting to the needs of large-scale production. For example, CN208151332U discloses a stirring device for the production of dry white wine lees, including a mixer with a cylindrical structure, a plurality of feed hoppers are arranged in an array around the upper part of the side wall of the mixer, and a motor cavity and a stirring cavity are separated inside the mixer by a support plate; the motor cavity is located at the upper part of the inner cavity of the mixer, and a driving motor is vertically installed at the center of the motor cavity; the lower end of the driving motor is connected to a stirring shaft; the upper end of the stirring shaft is rotatably mounted in the support plate through a bearing, and the lower end of the stirring shaft is rotatably mounted in the bottom wall of the stirring cavity through a bearing; a plurality of stirring rods are arranged in a radial array around the stirring shaft, and the stirring shaft includes a connecting handle and a rotating sleeve; the inner end of the connecting handle is provided with a connector of a threaded shaft structure, and the stirring rod and the stirring shaft are detachably fixedly threadedly connected through the connector. For another example, CN212504792U discloses an automatic turning device for fermenting white wine lees with brewer's yeast, which turns over and stirs the material inside the material bin by turning on the motor, so that the temperature inside the material bin is balanced and the taste of the brewed wine is improved; it includes a material bin, and a chamber is arranged inside the material bin; it also includes a first base, a first bracket, a second bracket, a third bracket, a fourth bracket, a second base, a motor, a main shaft and multiple groups of stirring blades, the top of the first base is connected to the bottom end of the material bin, the bottom ends of the first bracket, the second bracket, the third bracket and the fourth bracket are all connected to the top of the first base, the top ends of the first bracket, the second bracket, the third bracket and the fourth bracket are all connected to the bottom end of the second base, the top of the motor is connected to the bottom end of the second base, the top of the main shaft is connected to the bottom end of the motor, and the side ends of the multiple groups of stirring blades are all connected to the side ends of the main shaft.

[0004] The existing technologies have not solved the problem of how to achieve efficient and uniform mixing of high-moisture mash and high-viscosity grain. In addition, how to improve the mixing efficiency while avoiding damage to the mash shape and ensure the quality consistency of the final product is also an urgent problem to be solved in this field.

[0005] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making the present invention, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present invention does not have the characteristics of these prior arts. On the contrary, the present invention already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a method and device for efficiently mixing ingredients for liquor brewing, so as to solve at least part of the above-mentioned technical problems.

[0007] The invention discloses a high-efficiency material mixing device for liquor brewing, comprising: a silo unit, comprising a tank body for providing a mixing space; and a power unit, for mixing and breaking up materials entering the mixing space of the silo unit.

[0008] Preferably, the power unit arranged in the inner cavity of the tank body includes a telescopic stirring rod for adjusting the depth and range of stirring, a scattering blade for breaking up and mixing the materials, and an engaging motor for providing power, and the scattering blade is installed at the end of the telescopic stirring rod so that the engaging motor can drive the scattering blade to rotate when driving the telescopic stirring rod to rotate, wherein the scattering blade is a twisted sheet structure, and a plurality of through holes are opened on the scattering blade in a staggered manner, and the connecting line of the geometric structure centers of these holes can be arranged in a manner of being recessed toward the structural center of the closed structure formed by these connecting lines.

[0009] By adopting a twisted sheet-like structure of the breaking blade, arranging multiple cutting edges on its edge and opening through holes on its surface, the mixing device of the present invention can achieve deep breaking up and mixing of the material. This structural design is based on the principle of fluid mechanics, in which the cutting edge generates shear force when rotating, which helps to break up large pieces of material, and the fluid dynamics effects (such as turbulence effect, recirculating flow and shear stress) caused by the hole further enhance the dispersion and mixing of the material. These designs not only improve the mixing efficiency, but also ensure the uniformity of the mixing process, thereby helping to improve the quality and efficiency of material mixing in the liquor brewing process.

[0010] The base length of the specially designed scattering blade of the present invention is L b , the end length is L e , and L e >L b . Define three points on the scattering blade, the first center P1 = (x1, y1, z1), the second center P2 = (x2, y2, z2), and the third center P3 = (x3, y3, z3), which correspond to the relative positions of the base and end of the scattering blade respectively. Their perpendicular distances satisfy the following constraints:

[0011] d(P1,base(A))=d(P2,edge(A))=d(P3,edge(A))(1)

[0012] Among them, d(P i ,S) represents point P i The vertical distance to the edge of the blade.

[0013] Furthermore, the holes formed on the scattering blade may include three through holes, and the positions of the three through holes are defined as H1, H2, and H3, wherein the through hole H1 is located in a region close to the base of the scattering blade and satisfies:

[0014] H1=(x1+f1(L b ),y1+f2(L b ),z1+f3(L b )) (2)

[0015] Among them, f1, f2, f3 are linear or nonlinear functions describing the change of the base length. Similarly, the through holes H2 and H3 are arranged in the area close to the end of the blade, satisfying:

[0016] H2=(x2+f1(L e ),y2+f2(L e ),z2+f3(L e )),

[0017] H3=(x3+f1(L e ),y3+f2(L e ),z3+f3(L e )) (3)

[0018] The three holes H1, H2, and H3 defined in this way can form a quasi-triangle structure. Let the vertices of the quasi-triangle be P1, P2, and P3, and the length of its side satisfies:

[0019] |P1P2|=|P2P3|=|P3P1|=L (4)

[0020] Where L is the side length.

[0021] The concavity degree δ of the above-mentioned triangular closed structure satisfies the following conditions:

[0022]

[0023] Where C is the geometric center of the structure, d i is the distance from each point to the center.

[0024] For each hole H i , define its normal direction as vector According to the geometric design of the hole, the main direction of the normal satisfies:

[0025]

[0026] in, is the unit vector that breaks up the direction of blade motion. i The normal vector of or its component vector and the direction of motion If they are in the same direction, the normal direction is positive; if they are in opposite directions, it is negative; if they are perpendicular, there is no positive or negative direction.

[0027] Furthermore, the normal direction of the first through hole H1 is negative:

[0028]

[0029] The normal of the second through hole H2 has no positive or negative direction:

[0030]

[0031] The normal direction of the third through hole H3 is positive:

[0032]

[0033] Furthermore, for the second through hole H2, its normal direction The vector can point to the axis of the telescopic stirring rod and satisfy:

[0034]

[0035] in, is the axial component of the through-hole normal, is the component of the normal in the radial direction. The symmetry of the components of this vector ensures that its fluid flow characteristics have no obvious tendency. Through the mathematical calculation of the above normal direction and force distribution, the distribution and stress characteristics of the holes on the blade are accurately defined, so that the geometry of the relevant holes can be processed and verified.

[0036] According to a preferred embodiment, the telescopic stirring rod can adjust its length based on the depth of the tank body and the setting position of the engaging motor so that the breaking up blades can be placed in the mixing space, wherein the breaking up blades can be grouped in multiples and arranged in groups on the circumference of the telescopic stirring rod.

[0037] The adjustable length of the telescopic stirring rod allows the scattering blades to be optimally configured according to the specific depth of the tank and the position of the motor. This adjustment capability ensures that the scattering blades can effectively cover the entire mixing space to adapt to tanks of various sizes. As a result, the mixing device can adapt to production needs of different scales, improving the versatility and flexibility of the mixing device. In addition, by arranging the scattering blades in groups, the mixing device can increase the effective area while maintaining a compact structure, further improving the mixing efficiency and uniformity of material mixing.

[0038] According to a preferred embodiment, a group of breaking up blades are arranged at intervals in the same layer in the circumferential direction of the telescopic stirring rod, and the group of breaking up blades arranged in the same layer can be arranged symmetrically about the axis of the telescopic stirring rod, wherein one or more layers of breaking up blades can be arranged on the telescopic stirring rod.

[0039] A set of scattering blades are arranged symmetrically and circumferentially on one layer of the telescopic stirring rod, providing uniform force distribution for the mixing process. This layout reduces dead angles during the mixing process and ensures uniform mixing of materials throughout the mixing space. The torques generated by the symmetrically arranged blades when rotating offset each other, helping to maintain the balance of the stirring rod, reducing wear and energy consumption caused by asymmetrical loads, thereby extending the service life of the equipment and improving energy efficiency.

[0040] According to a preferred embodiment, the scattering blade includes a base for contacting the telescopic stirring rod, wherein the scattering blade can be arranged in a manner that the length direction of its base is not parallel to the axial direction of the telescopic stirring rod to form a preset inclination.

[0041] The tilted setting of the breaking blades not only shears the materials when the blades rotate, but also produces a "lifting-dispersing" effect. This design utilizes the tilt angle of the blades, so that the materials are sheared and dispersed along the tilt direction of the blades, thereby increasing the contact area between the materials and the mixing space and improving the mixing efficiency. In addition, the tilt setting also helps to reduce the direct friction between the blades and the materials, reduce wear, and further improve the durability and reliability of the mixing device.

[0042] According to a preferred embodiment, the overall shape of the breaking up blade is streamlined, expanding outward from the base and then contracting inward until reaching the end, and the two ends of the base and the two ends of the end can be transitioned by one or more arc sections respectively.

[0043] The streamlined design of the breaking blade expands outward from the base and then contracts inward to the end. This shape optimizes the interaction between the blade and the fluid, reduces fluid resistance, and improves mixing efficiency. The streamlined blade can guide the fluid more smoothly when rotating, increase the fluidity of the fluid, and thus promote the mixing of materials. The design of the end length being longer than the base increases the effective area of ​​the blade, allowing the blade to more effectively break up and mix the materials during the mixing process, further improving the mixing effect.

[0044] According to a preferred embodiment, the mixing device is equipped with a feeding unit on the silo unit for conveying temporarily stored materials to the mixing space of the silo unit, the feeding unit includes a temporary storage frame for temporarily storing materials and a feeding valve for regulating the connectivity between the temporary storage frame and the tank body, wherein the opening and closing power of the feeding valve comes from a meshing motor.

[0045] By connecting the opening and closing power of the feed valve to the meshing motor, the present invention achieves precise control of the feed process. This design allows the operator to accurately adjust the feed rate through the motor according to the needs of the mixing process, ensuring uniform addition of materials and avoiding the reduction of the mixing effect due to uneven feeding. In addition, this integrated design simplifies the mechanical structure of the equipment, reduces additional drive components, and reduces the complexity and maintenance cost of the equipment.

[0046] According to a preferred embodiment, the feed valve can be arranged in a relatively central area within the temporary storage frame, and a material slope with a preset inclination is arranged in the temporary storage frame in a manner surrounding the feed valve, wherein the material slope is arranged in a manner that the side close to the feed valve has a lower height than the side far from the feed valve.

[0047] The material slope with a preset inclination is set in the temporary storage frame, and the feed valve is set in a relatively central area. These designs together optimize the flow path of the material from the temporary storage frame to the tank. The inclined design of the material slope allows the material to flow naturally to the feed valve by gravity, reducing the need for additional transportation. At the same time, the central position of the feed valve helps to achieve uniform distribution of the material, avoiding accumulation or uneven distribution of the material when entering the tank, thereby improving the uniformity and efficiency of mixing.

[0048] According to a preferred embodiment, the analysis unit configured for the mixing device includes a detection component for collecting data information in the mixing space and a processing component for analyzing and calculating the collected data information, wherein the detection component can be arranged at the bottom of the telescopic stirring rod and is communicatively connected with the processing component.

[0049] The mixing device of the present invention realizes accurate monitoring and intelligent analysis of materials in the mixing space by configuring an analysis unit, including a flash camera as a detection component and a processing component of a built-in processor. The design of the flash camera can provide clear, high-resolution images in an environment with insufficient or uneven light, ensuring accurate identification of the state of the mash. This design is particularly suitable for poor light conditions commonly found in industrial environments, such as insufficient light caused by high temperature, high humidity or internal shading. The detection component is arranged at the bottom of the telescopic stirring rod, so that it can directly observe and capture images of the materials in the mixing space. This layout enables the camera to capture images instantly when the material is added to the tank body, providing real-time data for the processing component. By taking multiple photos continuously in a short period of time, the processing component can obtain a comprehensive view of the distribution and state of the material, thereby performing a more accurate analysis.

[0050] According to a preferred embodiment, the detection component is capable of collecting image information of materials entering the mixing space and transmitting it to the processing component, so as to utilize the built-in intelligent model of mash identification and mixing strategy for image recognition to distinguish different types of mash, and automatically generate corresponding mixing strategies based on the recognition results, thereby transmitting the mixing strategy to the execution program of the meshing motor in the form of preset values.

[0051] By embedding an intelligent model for identification and mixing strategies of fermented grains in the processing unit, the present invention realizes automatic identification of different types of fermented grains and generation of corresponding mixing strategies. This intelligent design enables the device to automatically adjust the mixing parameters according to the real-time image recognition results to adapt to the characteristics of different materials. This not only improves the flexibility and adaptability of the mixing process, but also reduces manual intervention, improving production efficiency and product quality.

[0052] The present invention also discloses a high-efficiency mixing method for liquor brewing, which comprises one or more of the following steps:

[0053] Start the analysis unit to obtain image information inside the tank and formulate a mixing strategy by visually identifying the mash;

[0054] After the material is transported, the meshing motor is started to execute the corresponding mixing strategy based on the preset execution program, so as to drive the telescopic stirring rod to drive the breaking blade to rotate, so that the breaking blade contacts and collides with the material in the tank, thereby mixing the material in the tank evenly under the action of centrifugal force.

[0055] The efficient mixing method for liquor brewing of the present invention obtains image information in the tank by starting the analysis unit, and formulates a mixing strategy by visually identifying the mash, which enables the mixing process to be optimized according to the actual state of the material. After the material is transported, the device can ensure that the material is evenly mixed under the action of centrifugal force by starting the meshing motor to execute the preset mixing strategy. This method not only improves the uniformity of mixing, but also ensures the continuity and efficiency of the production process, which helps to improve the overall quality and efficiency of liquor brewing.

DETAILED DESCRIPTION

[0066] The following is a detailed description with reference to the accompanying drawings.

[0067] Example 1

[0068] like Figure 1 As shown, the present invention discloses a high-efficiency mixing device for liquor brewing, which comprises: a silo unit 100 for providing a mixing space; a power unit 200 for mixing and breaking up the material entering the mixing space of the silo unit 100 .

[0069] Preferably, the tank unit 100 can be made of food-grade stainless steel to ensure the hygiene and safety of the winemaking process, wherein the tank unit 100 can include a tank body 110. Preferably, the tank body 110 can be of any three-dimensional structure. Considering the requirements for capacity and shape and factors such as floor space, the tank body 110 can generally be configured as a regular geometric three-dimensional structure, such as a conventional tank structure such as a cube or a cylinder. Preferably, the bottom and side walls of the tank body 110 can define an inner cavity, and the top of the tank body 110 can be fully or partially open so that other functional components and / or materials can enter the inner cavity of the tank body 110 from the top. In other words, the top of the tank body 110 can be provided with an opening.

[0070] Preferably, the power unit 200 disposed in the inner cavity of the tank body 110 may include a telescopic stirring rod 210 for adjusting the depth and range of stirring, a scattering blade 220 for scattering and mixing the materials, and a meshing motor 230 for providing power. Preferably, the scattering blade 220 may be installed at the end of the telescopic stirring rod 210 so that the meshing motor 230 can drive the scattering blade 220 to rotate in the same direction when driving the telescopic stirring rod 210 to rotate. Preferably, according to the depth of the tank body 110 and the setting position of the meshing motor 230, the scattering blade 220 can be placed in the mixing space by adjusting the length of the telescopic stirring rod 210, wherein the mixing space is a partial area defined in the inner cavity of the tank body 110 for stirring and scattering the materials, and the mixing space can be set close to the bottom of the tank body 110. Preferably, the bottom surface of the mixing space may be configured with a safety protection member, wherein the bottom of the safety protection member may be spherical in shape protruding toward the bottom of the tank body 110, and the edge of the spherical shape may partially extend in a direction away from the bottom of the tank body 110, thereby providing space for the rotation of the breaking blade 220.

[0071] Preferably, the scattering blades 220 of the present invention can be arranged in groups in the circumference of the telescopic stirring rod 210, wherein a group of scattering blades 220 can be directly connected to the telescopic stirring rod 210, or can be indirectly connected to the telescopic stirring rod 210 by first connecting to a ring member and then sleeved on the telescopic stirring rod 210. Preferably, a group of scattering blades 220 can be arranged at intervals on the same layer in the circumference of the telescopic stirring rod 210, wherein a group of scattering blades 220 arranged on the same layer can be symmetrically arranged about the axis of the telescopic stirring rod 210, and the symmetrical arrangement can be centrally symmetrical. Preferably, one or more layers of scattering blades 220 can be arranged on the telescopic stirring rod 210 according to actual working conditions to meet different production needs, wherein different layers of scattering blades 220 can be connected to different axial positions of the telescopic stirring rod 210. Exemplarily, Figure 2This is a schematic diagram of providing a layer of scattering blades 220 on the telescopic stirring rod 210. For the same telescopic stirring rod 210, at most three layers of scattering blades 220 can be stacked along the axial direction (ie, vertical direction Y) thereof.

[0072] Preferably, due to the high water content of the distilled mash, the strong viscosity of the grain after gelatinization, the large volume of the mixed materials, the uneven mixing, the great damage to the mash bone strength, the low efficiency and other disadvantages in the operation process, in order to achieve efficient mixing of the materials in the bin unit 100, according to the material characteristics of the distilled mash (i.e., lees) and the grain after cooking (i.e., the raw materials and auxiliary materials), the present invention has specially designed the scattering blade 220. Further, the scattering blade 220 adopts a three-dimensional generative streamlined curve shape design, and its edge has a plurality of cutting edges 221, and one or more holes 222 are opened on the scattering blade 220 to achieve efficient scattering and mixing of the materials, wherein the hole 222 can be set in a way of penetrating the scattering blade 220. Preferably, the scattering blade 220 may include a base 223 for contacting the telescopic stirring rod 210, wherein a reinforcing rib may be attached at the connection between the base 223 and the outer wall 211 of the telescopic stirring rod 210. Preferably, the base 223 of the scattering blade 220 is substantially a curved surface having the same curvature as the outer wall 211 of the telescopic stirring rod 210, wherein Figure 1 As shown, the length direction L1 of the base 223 of the scattering blade 220 is not parallel to the axial direction (i.e., the vertical direction Y) of the telescopic stirring rod 210, so that the scattering blade 220 can be arranged in a manner that its base 223 is inclined to the axial direction of the telescopic stirring rod 210, and a group of scattering blades 220 in the same layer can have the same inclination when arranged circumferentially around the telescopic stirring rod 210. This inclination allows the fluid to be pushed and mixed more effectively during rotation, thereby enhancing the scattering effect. Preferably, the overall shape of the scattering blade 220 is streamlined, and its base 223 is narrow and gradually expands outward, and then contracts inward until it reaches the end 224, wherein the length of the end 224 is greater than the length of the base 223, and the end 224 is generally a planar structure. Furthermore, unlike conventional blades of simple planar sheet structures, the scattering blade 220 of the present invention is a twisted sheet structure, and its twisting angle may be, for example, 120 degrees, so as to form a saddle-like structure, wherein the two highest points of the saddle-like structure are the upper endpoints of the base 223 and the end 224 of the scattering blade 220, and the two lowest points are the lower endpoints of the base 223 and the end 224 of the scattering blade 220, and the two upper endpoints are not at the same height, and the two lower endpoints are not at the same height, thereby forming an asymmetric structure. Preferably, as Figure 3As shown, the above-mentioned twisting angle refers to the rotation angle of the base 223 transitioning from the length direction L1 of the scattering blade 220 to the length direction L2 of the end 224 in the process of transitioning from the base 223 of the scattering blade 220 along the twisting direction of the surface 225 of the scattering blade 220 to the end 224 of the scattering blade 220. Preferably, as Figure 4 As shown, the upper end point of the base 223 (i.e., the first upper end point 226) is higher than the lower end point of the base 223 (i.e., the first lower end point 227) in the vertical direction Y; the upper end point of the end 224 (i.e., the second upper end point 228) is higher than the lower end point of the base 223 (i.e., the second lower end point 229) in the vertical direction Y, and the second upper end point 228 is higher than the first upper end point 226 in the vertical direction Y, and the second lower end point 229 is lower than the first lower end point 227 in the vertical direction Y. Further, the first upper end point 226 can be transitioned to the second lower end point 229 through one or more arcs with a downward trend, and the first lower end point 227 can be transitioned to the second upper end point 228 through one or more arcs with an upward trend, wherein, when transitioning through multiple arcs, arcs of different segments can have different degrees of downward or upward change rates, but even if the change rates of two adjacent arcs are different, they can be connected in a smooth transition manner. Preferably, the above transition arc is the structure of the cutting edge. Further preferably, the first upper endpoint 226 can transition to the second lower endpoint 229 through two arcs with different downward trends, and the arc near the second lower endpoint 229 (i.e., the second arc segment 232) has a greater downward trend than the arc near the first upper endpoint 226 (i.e., the first arc segment 231); the first lower endpoint 227 can transition to the second upper endpoint 228 through two arcs with upward trends, and the arc near the second upper endpoint 228 (the fourth arc segment 234) has a greater upward trend than the arc near the first lower endpoint 227 (the third arc segment 233).

[0073] Such a design can produce complex fluid dynamic effects during the mixing process to significantly enhance the ability to break up materials (especially viscous mash). Specifically, the three-dimensional generative streamlined curve shape design of the breaking blade 220 ensures that the fluid can smoothly bypass the breaking blade 220 during the mixing process, thereby reducing fluid resistance and improving mixing efficiency. The streamlined design is not a simple two-dimensional plane shape, but a three-dimensional surface generated by computer-aided design (CAD) and computational fluid dynamics (CFD) simulation, combined with material properties and actual working conditions. Such a design can minimize fluid resistance and enhance the fluid dynamics performance of the breaking blade 220. In addition, the streamlined design can also reduce the wear of the surface 225 of the breaking blade 220 and extend the service life of the breaking blade 220. For materials with high viscosity and easy to agglomerate, such as mash after distillation and grain after cooking, this design is particularly important because it can significantly improve the breaking and mixing effect of the breaking blade 220.

[0074] Preferably, the multiple cutting edges 221 arranged at the edge of the beating blade 220 in a transition arc structure can provide a strong shearing force, so that the mash particles are quickly decomposed under the action of high kinetic energy. The design of the cutting edge 221 not only considers the shape and angle of the cutting edge, but also the number and distribution of the cutting edges. Through reasonable design, the cutting edge 221 can produce a uniform and strong shear force on the material during the mixing process, thereby improving the beating efficiency. The cutting edge 221 can be made of high-strength stainless steel material, and after a special heat treatment process, it has excellent wear resistance and corrosion resistance, and can work stably for a long time under high-strength and high-corrosive working conditions.

[0075] Preferably, one or more holes 222 can be provided on the scattering blade 220 in a manner that induces complex fluid dynamic effects, wherein the fluid dynamic effects include turbulence effects, fluid recirculation, and shear stress. These effects can significantly enhance the scattering and mixing capabilities of the scattering blade 220 and improve the mixing efficiency. According to Bernoulli's principle, during the flow of a fluid, if the flow area is reduced, the flow velocity will increase, while the static pressure will decrease. The fluid will encounter contraction during the process of entering the hole 222, resulting in a reduction in the fluid flow area, thereby accelerating the flow. This acceleration process means that the kinetic energy of the fluid is enhanced, and it can pass through the hole 222 more efficiently.

[0076] Preferably, if Figure 5As shown, for the above-mentioned twisted sheet-like structure of the scattering blade 220, three independent holes 222 can be opened on its surface 225 in a penetrating manner, wherein the independent holes 222 mean that these holes 222 are not interconnected in structure, but it does not mean that the design parameters of the three holes 222 are unrelated to each other. The independently designed holes 222 provide multiple flow channels for the fluid in the stirring process, which helps the fluid to form a more uniform flow pattern during the stirring process. This flow pattern can reduce flow resistance and improve mixing efficiency. By providing a plurality of independent holes 222, it is possible to avoid dead zones in the fluid inside the mixing device, thereby improving the contact and mixing degree of the materials and ensuring that the materials in each area can be fully stirred. The holes 222 opened on the scattering blade 220 can be of various shapes, and preferably have a streamlined structure with no sharp corners on the edge, and in particular can be, for example, circular or quasi-circular. The circular or quasi-circular holes 222 can maintain good fluid dynamics during flow, reduce turbulence and flow resistance, and the streamlined structure can remain relatively smooth when the fluid passes through, reduce the generation of eddies, and avoid material accumulation at sharp corners. The design of the circular or quasi-circular holes 222 can evenly distribute stress, reduce the risk of material fatigue and breakage caused by local stress concentration, and is relatively simple to process, suitable for large-scale production and efficient manufacturing, and can also be applied to a variety of flow and mixing scenarios, and can adapt to different material characteristics.

[0077] Preferably, the three holes 222 opened on the scattering blade 220 of the twisted sheet structure may include a first through hole 235 relatively closer to the base 223 of the scattering blade 220, a second through hole 236 relatively closer to the second upper end 228 of the scattering blade 220, and a third through hole 237 relatively closer to the second lower end 229 of the scattering blade 220, wherein the first through hole 235, the second through hole 236, and the third through hole 237 respectively have respective geometric structure centers, namely, a first center 238, a second center 239, and a third center 240. Preferably, the first center 238 may be arranged on a line connecting the midpoint of the base 223 of the scattering blade 220 to the center of the end 224, and the second center 239 may be arranged in a manner higher than the first center 238 and the third center 240 may be arranged in a manner lower than the first center 238, so that the second center 239 and the third center 240 are respectively located on both sides of the first center 238, thereby forming three holes 222 of different heights. This staggered arrangement of holes 222 can form different flow speeds and pressure gradients when the fluid enters the holes 222. Based on fluid dynamics in physics, when the fluid flows in holes 222 at different heights, the speed will change due to gravity and pressure differences, thereby promoting mixing. Therefore, the multiple holes 222 arranged in a staggered manner can allow the fluid to interact in different channels, thereby promoting the mixing and dispersion of the materials, and further improving the overall stirring efficiency.

[0078] Preferably, the perpendicular distance from the first center 238 to the base 223 of the scattering blade 220 is equal to the perpendicular distance from the second center 239 and the third center 240 to the end 224 of the scattering blade 220, and because the length of the end 224 is greater than the length of the base 223, the second through hole 236 and the third through hole 237 can be arranged in a side-by-side manner in an area close to the end 224, and the first through hole 235 can be arranged alone in an area close to the base 223, so that the three holes 222 can be relatively evenly distributed on the scattering blade 220. Further, the first center 238, the second center 239 and the third center 240 are connected in pairs along the surface 225 of the scattering blade 220 to obtain a triangular closed structure, wherein the three sides of the closed structure are equal in length and are all concave toward the center of the structure. This triangular-shaped structure has high geometric stability and can effectively resist various forces generated during the mixing process, thereby preventing the scattering blade 220 from being deformed during high-speed operation due to the openings, thereby maintaining its working efficiency. In addition, the triangular-shaped design can evenly distribute the force applied to the scattering blade 220 during the mixing process, thereby reducing the phenomenon of local force concentration. The uniformity of this structure helps to improve the durability and service life of the scattering blade 220. In addition, through this design, the positions of the three holes 222 can be quickly located to ensure that the three holes 222 can be evenly distributed on the scattering blade 220, thereby helping to form consistent flow characteristics during the mixing process, avoiding poor flow in certain areas due to uneven layout of the holes 222, thereby ensuring good mixing of the materials.

[0079] Preferably, the three holes 222 on the breaking blade 220 may have different normal directions, and the above-mentioned different normal directions refer to the different main directions of these normals, rather than just that these normals are not parallel. The main direction of the normal of the hole 222 can be determined by judging its relationship with the direction of movement. If its normal or the component vector of the normal is in the same direction as the direction of movement, it is a positive normal direction; if its normal or the component vector of the normal is in the opposite direction to the direction of movement, it is a negative normal direction; in addition, if its normal or the component vector of the normal is perpendicular to the direction of movement, it is a normal direction with no positive or negative direction. In the present invention, the first through hole 235 may have a negative normal direction; the second through hole 236 may have a normal direction with no positive or negative direction, and the third through hole 237 may have a positive normal direction. Such an arrangement is conducive to the flow of fluid between the holes 222, thereby improving fluidity and shear force. Furthermore, for the second through hole 236, its normal can roughly point to the axis of the telescopic stirring rod 210, so that it has a normal direction without positive or negative directions, wherein the second through hole 236 with a normal direction without positive or negative directions mainly has no obvious tendency for forward flow and reverse flow of the fluid compared with the first through hole 235 and the third through hole 237, but it is not strictly limited that its normal must accurately point to the axis of the telescopic stirring rod 210.

[0080] Specifically, during the rotation of the beating blade 220, the holes 222 formed thereon can generate local turbulence when the mash flows through the surface 225 of the beating blade 220, thereby increasing the mixing degree of the fluid. The turbulence effect causes the small groups of mash to be continuously subjected to shear force in a rapidly changing fluid environment, thereby being more easily be broken up. The design of the holes 222 not only considers the shape and size of the holes 222, but also the number and distribution of the holes 222. Through reasonable design, the holes 222 can generate uniform and strong turbulence during the stirring process, thereby improving the beating effect.

[0081] Specifically, during the rotation of the dispersing blade 220, part of the mash can form a local recirculation flow through the hole 222 opened on the dispersing blade 220. This recirculation flow further enhances the effect of shear force and tearing force, so that the small mash clumps can be dispersed in a shorter time. The formation of the recirculation flow depends not only on the design of the hole 222, but also on the rotation speed of the dispersing blade 220 and the physical properties of the fluid. Through reasonable design and adjustment, the hole 222 can form a stable and strong recirculation flow during the stirring process, thereby further improving the dispersing effect.

[0082] Specifically, the presence of the hole 222 changes the pressure distribution on the surface 225 of the dispersing blade 220, and the fluid can generate a large shear stress when passing through the hole 222, which helps to disperse the mash particles that adhere together, thereby improving the dispersing effect. The magnitude of the shear stress depends not only on the design of the hole 222, but also on the rotation speed of the dispersing blade 220 and the physical properties of the fluid. Through reasonable design and adjustment, the hole 222 can generate uniform and strong shear stress during the stirring process, thereby further improving the dispersing effect.

[0083] If the design of the holes 222 causes the fluid flow path to become uneven, the flow rate may be reduced in some areas, thereby reducing the shear force in these areas. Therefore, the arrangement of the holes 222 is particularly critical, which affects the flow path of the fluid. Figure 6 As shown, the two scattering blades 220 adjacently arranged on the telescopic stirring rod 210 may have the same inclination angle. Based on the rotation direction of the stirring telescopic rod 210, Figure 6 The two scattering blades 220 shown in the figure can be divided into blades relatively forward in the rotation sequence (hereinafter referred to as the leading blades 220 - a ) and blades relatively backward in the rotation sequence (hereinafter referred to as the trailing blades 220 - b ). Figure 6The figure shows a partial flow path of the fluid under the action of the scattering blade 220. When the telescopic stirring rod 210 drives the scattering blade 220 to rotate, the fluid in the area before the preceding blade 220-a contacts the cutting edge 221 on the first arc segment 231 and / or the second arc segment 232 of the preceding blade 220-a, and moves roughly outward and backward along the front and back surfaces 225 of the preceding blade 220-a under the action of rotation and centrifugation, so as to reach the first through hole 235 with a negative normal direction and / or reach the third through hole 237 with a positive normal direction. At the first through hole 235, based on its negative normal direction, the fluid can more easily pass through the first through hole 235 from the back of the preceding blade 220-a to reach the front of the preceding blade 220-a. This part of the fluid can be mixed with the fluid flowing along the front of the preceding blade 220-a to reach the A region between the preceding blade 220-a and the succeeding blade 220-b, wherein, based on the structure of the surface 225 of the scattering blade 220, the A region can roughly correspond to the first arc segment 231 of the succeeding blade 220-b, so that the cutting edge 221 on the first arc segment 231 of the succeeding blade 220-b can scatter the fluid in the A region (especially the clumps in the fluid). In addition, most of the fluid in the A region can be located below the first arc segment 231 of the succeeding blade 220-b, and a small part of the fluid can be located above the first arc segment 231 of the succeeding blade 220-b, so that the fluid can circulate between a plurality of scattering blades 220 arranged based on the rotation sequence. At the third through hole 237, based on its positive normal direction, the fluid can more easily pass through the third through hole 237 from the front side of the preceding blade 220-a to reach the back side of the preceding blade 220-a. This part of the fluid can be mixed with the fluid flowing along the back side of the preceding blade 220-a to reach the second through hole 236 of the preceding blade 220-a. Under the centrifugal effect, part of the fluid that passes through the first through hole 235 and reaches the front side of the preceding blade 220-a will also flow along the front side of the preceding blade 220-a to the second through hole 236 of the preceding blade 220-a. Since the normal direction of the second through hole 236 has almost no positive or negative direction, it has no tendency for the forward or reverse passage of the fluid, and the fluid can adaptively switch between forward passage and reverse passage according to the pressure conditions on both sides of the second through hole 236. Exemplarily, Figure 6The flow velocity at the second through hole 236 located on the back side of the preceding blade 220-a is relatively greater, and its pressure is relatively smaller, so that the fluid located on the front side of the preceding blade 220-a can pass through the second through hole 236 and mix with the fluid located on the back side of the preceding blade 220-a. The mixed fluid can be further mixed with the fluid that reaches and turns over the end 224 to reach the back side of the preceding blade 220-a under the centrifugal effect, and the mixed fluid can reach the B area between the preceding blade 220-a and the succeeding blade 220-b, wherein, based on the structure of the surface 225 of the dispersing blade 220, the B area can be made to roughly correspond to the second arc segment 232 of the succeeding blade 220-b, so that the cutting edge 221 on the second arc segment 232 of the succeeding blade 220-b can disperse the fluid in the B area (especially the clumps in the fluid). In addition, most of the fluid in region B may be located above the second arc segment 232 of the subsequent blade 220-b, while a small portion of the fluid may be located below the second arc segment 232 of the subsequent blade 220-b, so that the fluid can circulate between multiple breaking up blades 220 arranged based on the rotation sequence.

[0084] When the distilled mash is mixed with raw materials such as cooked grains, the centrifugal action of the mixing device will have a certain impact on the moisture distribution of the material. This is because the centrifugal force generated by the high-speed rotation of the scattering blades 220 will cause heavier substances (such as solid particles) to move outward, while lighter substances (such as water) may be squeezed to the center. Especially when the viscosity of the mash is high, the centrifugal force will cause the water in the mash to separate from the solid particles, resulting in differences in moisture content in the stirred material, such as some areas being too wet while other areas are relatively dry. This uneven moisture distribution will affect the subsequent fermentation or processing process. The present invention's beating blade 220 with three holes 222 arranged at different heights can effectively alleviate the problem of water in the mash being separated from the solid due to centrifugal action. The three holes 222 arranged at different heights on the beating blade 220 can improve the fluidity of the beating blade 220, allowing water to flow more freely during the stirring process to promote fluids with different flow rates to pass through each hole 222, so that fluids with different flow rates pass through each hole, allowing the fluid to circulate at different heights when passing through the beating blade 220, increasing the contact area of ​​the fluid, which helps to mix water and solid particles more evenly and reduce water separation caused by centrifugal action. The holes 222 allow gas and liquid to pass through the beating blade 220, reducing the phenomenon of liquid being trapped on the outside of the beating blade 220 during stirring, thereby reducing the influence of centrifugal force on the liquid. In addition, the three holes are arranged based on different normal directions, so that the fluid can shuttle between the front and back of the scattering blade 220 based on its current flow state, and because the normal direction of the second through hole 236 has no positive or negative direction, the fluid can flexibly switch between the positive and reverse directions, which helps to quickly respond to the pressure changes of the fluid and form a more dynamic mixing environment. This design helps to evenly distribute the moisture in the material and avoid the situation where the water is too dense or too thin in some areas.

[0085] During the stirring process, the friction of the fluid may cause local overheating, which may cause some materials to react in an uneven temperature environment due to uneven heat distribution, affecting the fermentation speed and quality. In addition, excessively high temperatures may have a negative impact on the activity of yeast, and even cause yeast death, affecting the fermentation effect. In the present invention, the holes 222 are arranged in a staggered manner to increase the flow path of the fluid, promote more uniform dispersion of the fluid during the stirring process, and this dispersion helps to avoid local overheating or overcooling, thereby achieving a more uniform temperature distribution. The multiple holes 222 opened on the scattering blade 220 based on special rules allow the fluid to flow through different flow paths of the preceding blade 220-a respectively, and then merge in the A area and the B area between the preceding blade 220-a and the succeeding blade 220-b respectively, and then be scattered by the succeeding blade 220-b, thereby ensuring that the fluid is fully in contact with fluids of different temperatures during multiple mixing processes, which helps to evenly distribute the temperature. The circulation of the fluid in these areas allows the heat to be redistributed in the entire mixing space, ensuring the uniformity of the overall temperature.

[0086] Based on this, the present invention adopts fermentation engineering and fluid mechanics theory to conduct in-depth analysis and optimization of the particle size, stirring speed, blade thickness, breaking force and pore size of the mash to ensure that the stirring device can achieve the best stirring effect under different conditions.

[0087] Preferably, based on the fluid dynamic characteristics (including the fluid density of the mash, which is usually 1050 kg / m 3 ), combined with the actual stirring effect, the optimal range of stirring speed can be determined to ensure the integrity of the mash particles and the uniformity of stirring, wherein a stirring speed that is too fast may cause the mash particles to be over-grinded, destroying its fermentation activity; a speed that is too slow may cause uneven stirring, affecting the fermentation efficiency. Exemplarily, the rotation speed of the scattering blade 220 of the present invention can be set within the range of 6 to 10 RPM to provide sufficient cutting force and momentum.

[0088] Preferably, since the dynamic viscosity of the mash (usually 100 mPa·s) can affect the shear force and torque of the dispersing blade 220 during the stirring process, the optimal value of the blade thickness can be calculated in combination with the actual stirring effect when determining the blade thickness to ensure the strength and stirring efficiency of the dispersing blade 220. If the blade thickness is too small, it may not be able to withstand the shear force of the high-viscosity fluid, resulting in blade breakage; if the blade thickness is too large, the stirring resistance will be increased and the stirring efficiency will be reduced. Exemplarily, the blade thickness of the dispersing blade 220 of the present invention can be set to 20 cm.

[0089] Preferably, the particle density of the mash (usually 1200-1300 kg / m 3) and particle diameter (usually 0.1-2 mm) can affect the movement and mixing effect of the mash particles during the stirring process, and the friction coefficient between particles (usually 0.3-0.5) can affect the aggregation and dispersion of particles during the stirring process. Therefore, the optimal range of the breaking force can be determined based on the actual stirring effect, and the optimal design of the aperture can be determined accordingly, so that the suction force generated by the breaking blade 220 during rotation can effectively break up the lees agglomeration without destroying the particles, and ensure that the internal suction force during the stirring process can just suck the small lees agglomeration from the hole 222 to break it up. Further, if the breaking force is too small, the lees agglomeration may not be effectively broken up, affecting the fermentation effect; if the breaking force is too large, the mash particles may be destroyed, affecting the fermentation process. Further, the aperture design should take into account the internal suction force of the hole 222 on the breaking blade 220 on the mash particles, so as to ensure that the suction force that can effectively break up the agglomeration without blocking the hole 222 is generated during the stirring process. In addition, the angle of the cutting edge 221 provided on the edge of the scattering blade 220 can be set to, for example, 30 to 45 degrees. Such a design can reduce the wear of the cutting edge while ensuring the shear force.

[0090] The design of the dispersing blade 220 of the present invention fully utilizes the principles of fluid mechanics and mechanical cutting. When the telescopic stirring rod 210 rotates, the centrifugal force generated by the dispersing blade 220 and the shear force of the cutting edge 221 work together to rapidly decompose the small grains of mash under the action of high kinetic energy, and the turbulence effect of the surface 225 of the dispersing blade 220 is increased based on the design of the hole 222, further improving the dispersing efficiency. Furthermore, the design of the dispersing blade 220 is simulated and analyzed using fluid mechanics simulation software, and the simulation results show that within the set speed range, the shear stress and turbulence intensity generated by the surface 225 of the dispersing blade 220 are significantly higher than those of conventional blades without the hole 222 design, thereby improving the efficiency of dispersing the small grains of mash.

[0091] Preferably, the material mixing device of the present invention may be equipped with a feeding unit 400 on the silo unit 100 for conveying the temporarily stored materials to the mixing space of the silo unit 100, wherein Figure 2 and Figure 7 As shown, the feeding unit 400 includes a temporary material storage frame 410 for temporarily storing materials and a feeding valve 420 for regulating the communication state between the temporary material storage frame 410 and the tank body 110. Preferably, the temporary material storage frame 410 can be arranged at the opening of the tank body 110, and can be arranged in a manner that the radial dimension of its side wall is equal to the radial dimension of the opening of the tank body 110, so that the temporary material storage frame 410 and the tank body 110 can be sealed and connected. Further, the bottom of the temporary material storage frame 410 can have a radial dimension slightly larger than its side wall, so as to achieve partial protrusion relative to its side wall, thereby further improving the sealing performance.

[0092] Preferably, the feed valve 420 may be arranged in a relatively central area in the temporary material storage frame 410, so that the surrounding materials can enter the tank body 110 through the feed valve 420 located in the relatively central area. Furthermore, a material reverse slope 430 with a certain inclination may be arranged in the temporary material storage frame 410, wherein the material reverse slope 430 may be arranged around the feed valve 420, and is arranged in a manner that the side close to the feed valve 420 has a lower height than the side far from the feed valve 420, so that the materials in the temporary material storage frame 410 may have a tendency to move toward the feed valve 420 under the action of gravity, and when the feed valve 420 is opened, the materials may automatically pass through the feed valve 420 and enter the tank body 110 without the aid of external force.

[0093] Preferably, the feed valve 420 can be connected to the meshing motor 230 via the telescopic transmission shaft of the power unit 200 , so that the power output by the meshing motor 230 can be transmitted to the feed valve 420 via the telescopic transmission shaft to regulate the opening and closing of the feed valve 420 .

[0094] Preferably, if Figure 8 As shown, the mixing device of the present invention may also be provided with an analysis unit 300, which includes a detection component 310 for collecting data information in the mixing space and a processing component 320 for analyzing and calculating the collected data information, wherein the detection component 310 may be configured as a flash camera, and the processing component 320 may be configured as a processor, and the processing component 320 may be communicatively connected with the detection component 310 to receive the image information acquired thereby.

[0095] Furthermore, a flash camera is a digital camera device with a built-in flash, which can emit strong light instantly when shooting to supplement the lack of ambient light, thereby obtaining high-quality and clear images. In industrial applications, flash cameras usually have the characteristics of high resolution, fast focus and high frame rate, and can work stably in various harsh environments. The reason for using a flash camera is that it can ensure that the captured image is clear and bright by instantaneous fill light in the tank body 110, thereby improving the accuracy of identifying the type of fermented grains. During the stirring process, the light inside the tank body 110 may be uneven or insufficient due to occlusion, reflection and other reasons, and the flash camera can effectively compensate for this defect. In addition, the rotation of the telescopic stirring rod 210 may cause motion blur, but the instantaneous flash of the flash can effectively reduce this blur and ensure that each frame of the image is clear enough. Flash cameras usually have the characteristics of high resolution, fast focus and high frame rate, and can work stably under harsh conditions such as high temperature and high humidity to meet the needs of industrial production.

[0096] Preferably, the detection component 310 can be arranged at the bottom of the telescopic stirring rod 210 to obtain image information in the mixing space, wherein the detection component 310 can continuously take multiple photos in a short time to facilitate the analysis and calculation of the processing component 320. For example, the detection component 310 can continuously take 20 photos within 10 seconds. In addition, the processing chip built into the detection component 310 can process the taken photos to obtain the image information required by the processing component 320.

[0097] Furthermore, the processing component 320 may be equipped with an intelligent model for identification and mixing strategy of mash 320, so as to analyze the image information obtained by the flash camera through the model, and formulate different mixing strategies by identifying different mash 320, thereby improving the mixing efficiency. Preferably, the intelligent model for identification and mixing strategy of mash 320 is composed of a visual recognition layer (convolutional neural network) and a strategy decision layer (decision tree). Furthermore, the visual recognition layer can identify the mash 320 image taken in real time through a convolutional neural network to distinguish different types of mash 320; the strategy decision layer automatically generates the corresponding mixing strategy according to the recognition result based on the CART algorithm (classification and regression tree algorithm). Preferably, the CART algorithm is a decision tree algorithm for classification and regression tasks, which is to recursively divide the data set into smaller subsets to establish a tree model to predict the target variable, wherein, in the present invention, the classification depth of the decision tree is 3, the number of leaf nodes is 4, and each leaf node corresponds to a specific mixing strategy.

[0098] Specifically, when the mash enters the tank body 110, the detection component 310 located at the bottom of the telescopic stirring rod 210 can be started synchronously to complete the shooting task and transmit the acquired image information to the processing component 320, and then the processing component 320 completes the analysis operation. After the processing component 320 inputs the image information acquired by the detection component 310 into the mash identification and mixing strategy intelligent model, the model can automatically identify the type of mash, and then automatically specify the mixing strategy through the CART algorithm, and transmit the mixing strategy to the execution program of the meshing motor 230 in the form of preset values. When the mash is assembled, the meshing motor 230 can execute the corresponding mixing strategy based on the preset execution program.

[0103] The analysis unit 300 is started to obtain image information in the tank 110, and a mixing strategy is formulated by visually identifying the mash;

[0105] After the mixing is completed, the mixing uniformity of the materials in the tank 110 is evaluated to obtain the mash that meets the production process requirements.

[0106] Furthermore, if the evaluation result of the mixing uniformity of the materials in the tank body 110 is that the mixing uniformity does not meet the requirements, the mixing operation is continued until the requirements are met.
