Description

TECHNICAL FIELD

[0001] The present application relates to the field of liquor-making equipment, and provides a steel belt conveying structure and a spreading and airing device. BACKGROUND

[0002] In the process of liquor-making, the spreading and airing step is a crucial one, as it directly affects the quality of the final liquor. Traditional spreading and airing steps often use plate chain conveyors. While this method is simple, it has some obvious drawbacks.

[0003] Firstly, hygiene is a major concern with plate chain conveyors. Because of the gaps in the plate chain, grain debris and fermented grains can easily become trapped at the joints, providing a breeding ground for bacteria and mold, which poses a threat to the safety of the liquor.

[0004] Secondly, traditional plate chain conveyors also have problems in terms of efficiency and adaptability. Their speed is usually fixed, and they cannot adjust the thickness of the spread and the cooling time as needed, which can lead to over-fermentation of the fermented grains in certain areas, affecting the activity of microorganisms.

[0005] Finally, the maintenance cost of plate chain conveyors is relatively high, as the chain and the plate material can easily deteriorate in a humid and acidic environment, and need to be replaced frequently, increasing maintenance costs.

[0006] In summary, traditional plate chain conveyors have obvious shortcomings in terms of hygiene, efficiency, and maintenance costs. SUMMARY

[0007] The embodiments of the present application provide a steel belt conveying structure to solve the defects of easy material leakage and poor cooling effect in related technologies.

[0008] The embodiments of the present application also provide a spreading and airing device.

[0009] The first aspect of the embodiments of the present application provides a steel belt conveying structure for spreading and airing materials in the process of liquor-making, comprising: a chain; a composite steel belt plate connected to the chain through a steel belt clamp assembly; wherein the composite steel belt plate is sequentially stacked from bottom to top in the vertical direction and comprises: a ventilation punched inner layer, a plurality of ventilation holes being formed on the ventilation punched inner layer; an aluminum honeycomb composite heat dissipation layer, the aluminum honeycomb composite heat dissipation layer being fixed above the ventilation punched inner layer and forming a longitudinal air guide channel through itself; a food-grade silica gel anti-slip functional layer, the food-grade silica gel anti-slip functional layer being applied above the aluminum honeycomb composite heat dissipation layer and being used to directly load materials.

[0010] According to one embodiment of the present application, the ventilation punched inner layer is a stainless steel punched plate.

[0011] According to one embodiment of the present application, the aluminum honeycomb composite heat dissipation layer is fixedly connected with the ventilation punched inner layer by welding.

[0012] According to one embodiment of the present application, the longitudinal air guide channels of the aluminum honeycomb composite heat dissipation layer are in one-to-one correspondence with the plurality of ventilation holes formed on the ventilation punched inner layer, so as to form a channel allowing the cooling air flow to vertically penetrate the composite steel belt plate.

[0013] According to one embodiment of the present application, the surface of the food-grade silica gel anti-slip functional layer is pressed with a plurality of anti-slip convex points for increasing friction.

[0014] According to one embodiment of the present application, the anti-slip convex points are rhombic anti-slip convex points.

[0015] According to one embodiment of the present application, the height of the rhombic anti-slip convex points is 3 mm.

[0016] According to one embodiment of the present application, the steel belt conveying structure further comprises an air supply device arranged below the composite steel belt plate, and the air supply device is used to provide a cooling air flow from bottom to top.

[0017] The second aspect embodiment of the present application provides a spreading and airing device, which comprises the steel belt conveying structure as described above.

[0018] According to one embodiment of the present application, the spreading and airing device further comprises an air supply device arranged below the steel belt conveying structure, and the cooling air flow generated by the air supply device sequentially passes through the ventilation punched inner layer and the aluminum honeycomb composite heat dissipation layer of the steel belt conveying structure, so as to cool the material carried on the anti-slip functional layer.

[0019] According to the steel belt conveying structure provided by the embodiment of the first aspect of the present application, the composite steel belt plate is an integrated structure, and the surface is free of the joints and gaps of traditional plate chains. The anti-skid function of the food-grade silica gel anti-skid function layer can effectively prevent the material from falling from the gaps or spilling due to sliding during the conveying process, greatly reduces the material loss, improves the material utilization rate, and solves the defect of material leakage at the joint of the traditional plate chain conveying belt. The ventilation holes of the ventilation punched inner layer and the longitudinal air guide channels of the aluminum honeycomb composite heat dissipation layer form a vertically penetrating air flow path, so that the cooling air flow can uniformly and smoothly penetrate to the bottom of the material and quickly take away the heat of the material. The heat conduction characteristics of the aluminum honeycomb structure accelerate heat transfer, avoid local high temperature of the material, ensure uniform cooling of the material, and are beneficial to maintaining microbial activity and improving subsequent fermentation effect and liquor quality. The integrated composite structure has no residual dead angle, and the surface of the food-grade silica gel material is smooth, which is not easy to adhere to grain debris and fermented grains, and reduces the breeding bed of bacteria and mold. At the same time, the smooth surface and the jointless design are convenient for cleaning, and the surface stains can be quickly removed by wiping or washing, which meets the sanitary requirements of liquor brewing and solves the cleaning difficulty of the traditional plate chain conveying belt. The three-layer composite structure synergistically enhances the overall strength and wear resistance of the steel belt plate, the corrosion-resistant material can adapt to the humid and acidic environment and is not easy to age and deform, and compared with the plate material of the traditional plate chain, the service life is significantly prolonged. The firm connection of the chain and the steel belt plate reduces the probability of part loosening or damage, reduces the maintenance cost of frequent replacement of parts, and improves the operation stability of the equipment. The composite steel belt plate is flat and the stress is balanced, the conveying speed can be flexibly adjusted, and then the material spreading thickness and cooling time can be adjusted, which is suitable for different brewing process requirements, solves the poor process adaptability problem caused by the fixed speed of the traditional plate chain conveying belt, and improves the practicality and flexibility of the equipment.

[0020] According to the second aspect of the present invention, the spreading and drying equipment features a three-layer composite design and continuous conveying mode of the steel belt conveyor structure. This ensures that the material is continuously subjected to airflow during movement. The synergistic use of the aluminum honeycomb composite heat dissipation layer and the ventilated perforated inner layer ensures that the cooling airflow penetrates the material evenly, avoiding the problem of insufficient local cooling in traditional spreading and drying equipment. This significantly improves spreading and drying efficiency, shortens material cooling time, and meets the process rhythm requirements of baijiu brewing. The anti-slip design of the food-grade silicone anti-slip functional layer and the seamless structure of the composite steel belt effectively prevent material from spilling or leaking through gaps during conveying and spreading, reducing material loss, improving material utilization, lowering the production cost of baijiu brewing, and solving the problem of serious material leakage in traditional plate chain conveyors. The equipment has no unsanitary dead corners. The food-grade material and seamless design of the composite steel belt reduce the residue of grain debris and mash, reducing the risk of bacterial or mold growth. At the same time, the equipment is easy to clean, can quickly remove surface stains, meets the hygiene standards of baijiu brewing, and ensures the safety of the liquor quality from the source. The drive unit adjusts the operating speed of the steel belt conveyor structure. Combined with the thickness adjustment of the feeding device, it allows for flexible adjustment of the material spreading thickness and cooling time, adapting to the spreading requirements of different types and batches of materials. This solves the problem of poor process adaptability caused by the fixed speed of traditional plate chain conveyors, improving the flexibility of the production process. The composite steel belt plate of the steel belt conveyor structure is made of corrosion-resistant and wear-resistant materials, capable of adapting to the humid and acidic working environment of liquor brewing, and is not prone to aging or deformation. The robust connection between the chain and the steel belt plate reduces the probability of component loosening or damage, lowers maintenance costs associated with frequent component replacement, and extends the overall service life of the equipment.

[0026] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0027] like Figs. 1-3 As shown, a first aspect of the present invention provides a steel belt conveyor structure for spreading and cooling materials during the brewing process of baijiu (Chinese liquor), comprising: Chain 100; Composite steel strip plate 102 connected to chain 100 via steel strip clamp assembly; Among them, the composite steel strip plate 102 is arranged in layers from bottom to top along the vertical direction: Ventilation perforated inner layer 104, with a plurality of ventilation holes provided on the ventilation perforated inner layer 104; An aluminum honeycomb composite heat dissipation layer is fixed above the inner layer 104 of the ventilation holes, forming a longitudinal air guide channel that runs through it. Food-grade silicone anti-slip functional layer 106 is applied on top of the aluminum honeycomb composite heat dissipation layer and is used to directly support materials.

[0028] According to the steel belt conveying structure provided by the first aspect of the present application, the composite steel belt plate 102 is an integrated structure, and the surface is free of traditional plate chain joints and gaps. In combination with the anti-skid function of the food-grade silica gel anti-skid function layer 106, the material can be effectively prevented from falling from the gap or spilling due to sliding during the conveying process, the material loss is greatly reduced, the material utilization rate is improved, and the defects of material leakage at the joint of the traditional plate chain conveying belt are solved. The ventilation holes of the ventilation and punching inner layer 104 and the longitudinal air guide channels of the aluminum honeycomb composite heat dissipation layer form a vertically penetrating air flow path, so that the cooling air flow can uniformly and smoothly penetrate to the bottom of the material and quickly take away the heat of the material. The heat conduction characteristics of the aluminum honeycomb structure accelerate heat transfer, avoid local overheating of the material, ensure uniform cooling of the material, and are beneficial to maintaining microbial activity and improving subsequent fermentation effect and liquor quality. The integrated composite structure has no residual dead angle, and the surface of the food-grade silica gel material is smooth and not easy to adhere to grain debris and fermented grains, reducing the breeding bed of bacteria and mold. At the same time, the smooth surface and the jointless design facilitate cleaning, and the surface stains can be quickly removed by wiping or washing, which meets the sanitary requirements of liquor brewing and solves the cleaning difficulty of the traditional plate chain conveying belt. The three-layer composite structure synergistically enhances the overall strength and wear resistance of the steel belt plate 102, and the corrosion-resistant material can adapt to a humid and acidic environment and is not prone to aging and deformation, so the service life is significantly prolonged compared with the traditional plate chain plate. The firm connection of the chain 100 and the steel belt plate 102 reduces the probability of part loosening or damage, reduces the maintenance cost of frequent replacement of parts, and improves the operation stability of the equipment. The composite steel belt plate 102 is flat and balanced in stress, can flexibly adjust the conveying speed, and then adjust the material spreading thickness and cooling time, adapt to different brewing process requirements, solve the poor process adaptability problem caused by the fixed speed of the traditional plate chain conveying belt, and improve the practicality and flexibility of the equipment.

[0029] Please continue to see Figs. 1-3 The steel belt conveying structure provided by the first aspect of the present application solves the problems of material leakage and poor cooling effect of the traditional plate chain conveying belt through the synergistic design of the three-layer composite structure.

[0030] The chain 100 is a power transmission component of the conveying structure, and moves circularly along the conveying direction and is firmly connected with the composite steel belt plate 102 through a steel belt clamp assembly. The steel belt clamp assembly includes a clamping plate and a fastener, and the clamping plate is respectively attached to the upper and lower surfaces of the edges of the composite steel belt plate 102 and is locked and fixed through the fastener, so as to ensure that the composite steel belt plate 102 moves synchronously with the chain 100 and does not slide or fall off. The spacing of the clamp assembly is uniformly distributed along the chain 100, which is adapted to the length of the composite steel belt plate 102, so that the steel belt plate 102 is balanced in stress and remains flat during the conveying process without bending deformation.

[0031] The composite steel belt plate 102 is sequentially stacked in an integrated structure along the vertical direction from bottom to top, and each layer is tightly attached without loose gap.

[0032] The ventilation punched inner layer 104 is a flat plate structure, and is made of corrosion-resistant material. A plurality of ventilation holes are uniformly arranged on the surface of the ventilation punched inner layer 104. The ventilation holes are regularly distributed, which not only ensures smooth airflow penetration, but also maintains the structural strength of the plate. The ventilation punched inner layer 104 serves as the foundation support of the entire composite plate, and bears the weight of the two upper layers and transmits the power.

[0033] The aluminum honeycomb composite heat dissipation layer is fixed on the upper surface of the ventilation punched inner layer 104, and has a honeycomb structure. The aluminum honeycomb composite heat dissipation layer has a longitudinal air guide channel formed inside. The aluminum honeycomb composite heat dissipation layer is made of aluminum material, has good heat conduction performance, and can quickly conduct the heat of material transmission. The longitudinal air guide channel corresponds to the position of the ventilation holes of the ventilation punched inner layer 104, and forms an airflow channel.

[0034] The food-grade silica gel anti-slip functional layer 106 is arranged on the upper surface of the aluminum honeycomb composite heat dissipation layer. The food-grade silica gel anti-slip functional layer 106 is made of food-grade silica gel, is non-toxic and odorless, and meets the hygiene requirements of liquor brewing. The food-grade silica gel anti-slip functional layer 106 directly contacts with the material. The surface of the food-grade silica gel anti-slip functional layer 106 is treated to enhance the friction. The silica gel material has a certain flexibility, and can buffer the impact of the material and the conveying belt.

[0035] The ventilation punched inner layer 104 and the aluminum honeycomb composite heat dissipation layer are tightly connected through a fixed manner, and the structural integrity is ensured. The ventilation punched inner layer 104 and the aluminum honeycomb composite heat dissipation layer do not separate from each other under the impact of conveying and airflow. The longitudinal air guide channel of the aluminum honeycomb composite heat dissipation layer is accurately aligned with the ventilation holes of the ventilation punched inner layer 104, and forms a vertical airflow path. The cooling airflow can penetrate the entire composite steel belt plate 102 from the bottom to the top, and acts on the material carried on the upper layer. The food-grade silica gel anti-slip functional layer 106 is fixedly connected with the aluminum honeycomb composite heat dissipation layer. The surface of the food-grade silica gel anti-slip functional layer 106 is flat, and does not affect the airflow passing through the gap between the layers. The food-grade silica gel anti-slip functional layer 106 can effectively carry the material and avoid material leakage.

[0036] The entire composite steel belt plate 102 has no joints and gaps, which avoids the residues of grain debris and fermented grains, and reduces the breeding of bacteria and mold. The edges of the steel belt plate 102 are polished and treated, and have no sharp protrusions, which prevents scratching the material or workers. The thickness of the composite structure is suitable for conveying requirements, which ensures the structural strength and does not excessively increase the conveying resistance. The composite structure is suitable for the humid and acidic working environment in the liquor brewing process.

[0037] The structure of the chain 100, the steel belt clamp assembly, and the composite steel belt plate 102 and the connection mode between them will be introduced and described below.

[0038] The chain 100 is the power transmission core component of the steel belt conveying structure, made of high-strength alloy material, with wear-resistant and corrosion-resistant properties, and can adapt to the humid and acidic working environment in the liquor brewing process. The chain link structure of the chain 100 is optimized and designed, and the connection between adjacent chain links is compact and flexible, ensuring smooth power transmission without jamming or jerk. The chain 100 is arranged horizontally along the conveying direction, and the two ends are tensioned by sprockets. The sprocket is fixedly connected with the output shaft of the driving device, and the driving device drives the sprocket to rotate, thereby driving the chain 100 to move in a cycle. The length of the chain 100 is customized according to the conveying requirements and is distributed along the full length of the rack to provide uniform support and power transmission points for the composite steel belt plate 102, ensuring that the composite steel belt plate 102 is evenly stressed during conveying and does not tilt or deform locally. The surface of the chain 100 is treated to prevent rust, reduce corrosion and aging in a humid environment, prolong the service life, and reduce the frequency of maintenance and replacement.

[0039] The steel belt clamp assembly is a key component connecting the chain 100 and the composite steel belt plate 102. Each set of clamp assembly includes two clamping plates and two or more fasteners. The clamping plate is arc-shaped and fits the chain 100. The inner side fits the upper and lower surfaces of the edge of the composite steel belt plate 102, and the outer side tightly fits the chain link of the chain 100, ensuring the stability of the connection. The clamping plate is made of high-strength stainless steel, which has enough rigidity and toughness to withstand the weight of the composite steel belt plate 102 and the material, and avoids stress deformation. The fastener is designed to prevent loosening. By tightening the fastener, the clamping plate, the composite steel belt plate 102 and the chain 100 are firmly locked to prevent loosening caused by vibration or material impact during conveying. The steel belt clamp assembly is evenly distributed along the chain link of the chain 100, and the spacing between adjacent clamp assemblies is adapted to the length of the composite steel belt plate 102, ensuring that both ends and the middle of the composite steel belt plate 102 are stably supported and remain flat during conveying without bending or warping. The edges of the clamp assembly are polished without sharp protrusions to avoid scratching the composite steel belt plate 102 or the workers.

[0040] The composite steel belt plate 102 is the core load-bearing component of the conveying structure, and is in the shape of a rectangular flat plate. The composite steel belt plate 102 is stacked in the vertical direction from bottom to top to form a ventilation punched inner layer 104, an aluminum honeycomb composite heat dissipation layer, and a food-grade silica gel anti-slip functional layer 106. The three layers are tightly connected to form an integrated structure without loose gaps. The ventilation punched inner layer 104 is a food-grade stainless steel punched plate with a plurality of circular ventilation holes uniformly arranged on the surface. The ventilation holes are uniformly distributed along the plate to ensure smooth airflow penetration and maintain the structural strength of the plate. The aluminum honeycomb composite heat dissipation layer is fixed above the ventilation punched inner layer 104 and has a honeycomb structure with vertical longitudinal air guide channels formed inside. The channels correspond to the ventilation holes and have both heat conduction and air guide functions, which can quickly conduct material heat and guide airflow to vertically penetrate. The food-grade silica gel anti-slip functional layer 106 is laid on the aluminum honeycomb composite heat dissipation layer and is non-toxic and odorless. The surface is pressed with rhombic anti-slip protrusions that are uniformly distributed to enhance the friction with the material and prevent the material from sliding and falling. The edges of the composite steel belt plate 102 are chamfered to avoid scratching the material or the workers, and are adapted to the clamping structure of the steel belt clamp assembly to ensure firm connection.

[0041] The chain 100, the steel belt clamp assembly, and the composite steel belt plate 102 are connected through detachable rigid connection to form a complete conveying unit. During the connection process, the edges of the composite steel belt plate 102 are placed above the chain links of the chain 100 to ensure that the center line of the plate is parallel to the movement direction of the chain 100, avoiding material deviation during conveying. Then, the upper and lower clamping plates of the steel belt clamp assembly are respectively attached to the upper and lower surfaces of the edges of the composite steel belt plate 102, and the outer sides of the clamping plates are tightly attached to the chain links of the chain 100 to ensure uniform distribution of the stress points. Next, the fasteners are passed through the connection holes of the clamping plates and the chain 100, and after being tightened, the three are firmly locked. The tightening torque of the fasteners is optimized to ensure the stability of the connection and avoid excessive tightening that causes deformation of the edges of the composite steel belt plate 102. Each set of composite steel belt plate 102 is connected to the chain 100 through at least two sets of steel belt clamp assemblies and is fixed at both ends of the plate. Additional clamp assemblies are added to the middle region of the large composite steel belt plate 102 to further improve the connection stability. After the connection is completed, the composite steel belt plate 102 and the chain 100 form a synchronous movement relationship. The circular movement of the chain 100 drives the composite steel belt plate 102 to move smoothly along the conveying direction without relative sliding or displacement, ensuring the stability of the material conveying. This connection method is convenient to disassemble, which facilitates the maintenance, cleaning, or replacement of the composite steel belt plate 102, while ensuring the overall rigidity and stability of the conveying structure.

[0042] According to one embodiment of the present application, the ventilation punched inner layer 104 is a stainless steel punched plate.

[0043] In an embodiment of the present application, the ventilation punched inner layer 104 adopts a stainless steel punched plate as the base support and ventilation carrier of the composite steel belt plate 102.

[0044] The ventilation punched inner layer 104 is made of food-grade stainless steel, which has the characteristics of corrosion resistance and rust resistance, and can adapt to the humid and acidic environment in the liquor brewing process. The plate as a whole is flat, with a thickness that meets the support requirements, and a plurality of ventilation holes are uniformly arranged on the surface. The ventilation holes are circular and uniformly distributed along the surface of the plate, ensuring that the airflow can penetrate uniformly.

[0045] The distribution density of the ventilation holes is optimized to ensure sufficient ventilation area without affecting the structural strength of the plate. The spacing between adjacent ventilation holes is uniform, allowing the cooling airflow to penetrate uniformly from below, avoiding local poor ventilation. The diameter of the ventilation holes is adapted to the longitudinal air ducts of the aluminum honeycomb composite heat dissipation layer, ensuring smooth airflow transmission and reducing wind resistance.

[0046] The upper surface of the stainless steel punched plate is tightly attached to the aluminum honeycomb composite heat dissipation layer and fixedly connected by welding. There is no gap at the connection site to ensure the structural integrity. The edges of the plate are adapted to the steel belt clamp assembly, which is firmly connected to the chain 100 through the clamp assembly, driving the composite steel belt plate 102 to move synchronously, maintaining structural stability during material conveying without deformation or loosening.

[0047] The stainless steel material has high strength and corrosion resistance, and can withstand the weight of the material and the tension during conveying, and is not prone to aging and deformation in a humid and acidic environment. Compared with traditional plate chain conveyor belts, the service life is significantly extended, reducing maintenance costs caused by frequent replacement.

[0048] The uniformly distributed ventilation holes allow the cooling airflow to penetrate vertically and uniformly, in combination with the air ducts of the aluminum honeycomb composite heat dissipation layer, forming a stable penetrating airflow and avoiding the problem of insufficient local cooling of the material caused by uneven ventilation in traditional plate chain systems, thereby improving the spreading efficiency.

[0049] The smooth surface of the stainless steel does not easily retain material, reducing the breeding ground for bacteria and mold and reducing the risk of wine contamination. At the same time, it is easy to clean, reducing the cleaning workload and meeting the hygiene standards of liquor brewing, thereby improving product safety.

[0050] According to an embodiment of the present application, the aluminum honeycomb composite heat dissipation layer and the ventilation punched inner layer 104 are fixedly connected by welding.

[0051] In an embodiment of the present application, the aluminum honeycomb composite heat dissipation layer and the ventilation punched inner layer 104 are fixedly connected by welding, forming a stable composite structure.

[0052] The bottom of the aluminum honeycomb composite heat dissipation layer is completely attached to the upper surface of the ventilation punched inner layer 104 without gaps or impurities. The welding adopts spot welding, and the welding spots are uniformly distributed along the edges and the middle of the aluminum honeycomb composite heat dissipation layer, ensuring uniform connection strength and not damaging the integrity of the two-layer structure.

[0053] The welding process is adapted to the characteristics of stainless steel and aluminum honeycomb material, and low-temperature welding technology is selected to avoid deformation of the aluminum honeycomb composite heat dissipation layer or changes in the performance of the stainless steel punched plate caused by high temperature. The size and spacing of the welding spots are optimized to ensure sufficient connection strength without blocking the ventilation holes or longitudinal air guide channels, ensuring smooth airflow.

[0054] After welding, the aluminum honeycomb composite heat dissipation layer and the ventilation punched inner layer 104 form an inseparable whole structure, which will not shift or separate during the transportation of materials, withstand air impact or cleaning process. The edges of the composite structure are polished to avoid scratching materials or workers.

[0055] The upper surface of the composite structure after welding is flat, providing a stable foundation for the laying of the food-grade silicone anti-slip functional layer 106, ensuring that the anti-slip functional layer can be closely attached without falling off or wrinkling, and ensuring the stability of the load-bearing material.

[0056] Welding connection makes the two-layer structure form a stable whole, which is stronger in tensile and impact resistance than bonding and other methods, can withstand the weight of the material and the dynamic load during transportation, avoids structural failure caused by interlayer separation, and prolongs the service life of the composite steel belt plate 102.

[0057] Welding connection has no gap, avoiding air leakage between layers, ensuring that all cooling air passes through the longitudinal air guide channel and penetrates upward, reducing wind resistance loss, improving air utilization rate, and thus enhancing the cooling effect and shortening the spreading time.

[0058] The whole structure does not shift or shift between layers during movement, can stably carry materials, avoids material spilling caused by loose structure, reduces material leakage, and improves the safety and material utilization rate of the transportation process.

[0059] According to one embodiment of the present application, the longitudinal air guide channels of the aluminum honeycomb composite heat dissipation layer and the plurality of ventilation holes opened on the ventilation punched inner layer 104 are one-to-one corresponding and communicated to form a channel allowing cooling air to vertically penetrate the composite steel belt plate 102.

[0060] In one embodiment of the present application, the longitudinal air guide channels of the aluminum honeycomb composite heat dissipation layer and the ventilation holes of the ventilation punched inner layer 104 are one-to-one corresponding and communicated to form a complete air flow channel.

[0061] The longitudinal air guide channel of the aluminum honeycomb composite heat dissipation layer penetrates the entire heat dissipation layer in the vertical direction, the number and position of the channel correspond to the air vents of the ventilation punched inner layer 104, and each air vent corresponds to a longitudinal air guide channel above it. The aperture of the channel is consistent with the aperture of the air vent to ensure that the airflow passes through without obstruction.

[0062] The lower end of the longitudinal air guide channel is precisely aligned with the air vent, and there is no misalignment or gap at the connection, forming a vertical penetrating airflow channel from the bottom of the ventilation punched inner layer 104 to the top of the aluminum honeycomb composite heat dissipation layer. The inner wall of the channel is smooth without burrs or protrusions, reducing the resistance when the airflow passes through and ensuring stable airflow speed.

[0063] The one-to-one correspondence distribution of the longitudinal air guide channel and the air vent allows the cooling airflow to be evenly distributed to each area of the composite steel strip plate 102, avoiding local airflow concentration or poor flow. The honeycomb structure of the aluminum honeycomb composite heat dissipation layer has heat conduction function, which can quickly conduct the heat of the material and cooperate with the airflow to remove heat, realizing the synergy of heat dissipation and ventilation.

[0064] The design of the airflow channel is adapted to the airflow output of the air supply device below, and the cooling airflow generated by the air supply device can completely enter the longitudinal air guide channel through the air vent, penetrate vertically to the food-grade silica gel anti-slip functional layer 106, and directly act on the bottom of the material, improving the cooling efficiency.

[0065] The vertically penetrating airflow channel allows the cooling airflow to directly and evenly act on the material, avoiding cooling delay caused by airflow dispersion or detouring, and significantly improving the cooling efficiency compared to the uneven ventilation of traditional plate chains, effectively shortening the material spreading time and improving the production efficiency.

[0066] The evenly distributed airflow channel allows each part of the material to be evenly affected by the cooling airflow, avoiding local high or low temperature, ensuring consistent material temperature, which is beneficial to the stability of microbial activity and improves the final wine quality.

[0067] The unobstructed airflow channel reduces airflow leakage and resistance loss, and the air supply device does not need to output excessive power to obtain sufficient penetrating airflow, reducing energy consumption and saving production cost.

[0068] Stable airflow transmission can adapt to the spreading of materials of different thicknesses, and even if the material is thick, the airflow can still penetrate to the bottom of the material, ensuring that the deep layer of the material can also be effectively cooled, and enhancing the adaptability of the device to different process requirements.

[0069] According to one embodiment of the present application, the surface of the food-grade silica gel anti-slip functional layer 106 is pressed with a plurality of anti-slip protrusions for increasing friction.

[0070] In one embodiment of the present application, the surface of the food-grade silica gel anti-slip functional layer 106 is pressed with a plurality of anti-slip protrusions to enhance the stability of the material bearing.

[0071] The food-grade silica gel anti-skid functional layer 106 is made of food-grade silica gel material, non-toxic and odorless, and meets the hygiene standards for liquor brewing, and has good flexibility and wear resistance. The anti-skid convex points are integrally formed on the surface of the silica gel layer and are in a convex shape, and the material is consistent with the silica gel layer and is not easy to fall off or wear out.

[0072] The anti-skid convex points are evenly distributed along the surface of the silica gel layer and cover the entire bearing surface. The spacing between adjacent convex points is optimized to ensure sufficient anti-skid effect and not to affect airflow passing and material heat dissipation. The distribution density of the convex points is adapted to the material characteristics to ensure uniform friction between the material and the silica gel layer and avoid local skidding.

[0073] The shape of the anti-skid convex points is designed to increase the contact friction with the material and effectively prevent the material from sliding or spilling due to vibration, inclination or acceleration and deceleration during the conveying process. The gap between the convex points can accommodate a small amount of material debris to avoid the accumulation of debris affecting the anti-skid effect, while facilitating airflow circulation and not hindering cooling.

[0074] The lower surface of the food-grade silica gel anti-skid functional layer 106 is closely attached to the upper surface of the aluminum honeycomb composite heat dissipation layer and is fixed by heat pressing or bonding. The attachment surface is free of bubbles or gaps to ensure that it does not fall off or wrinkle during material loading and cleaning, maintaining a flat structure.

[0075] The anti-skid convex points increase the friction between the material and the silica gel layer, effectively preventing the material from sliding and spilling due to the smoothness of traditional conveying belts, especially during acceleration, deceleration or turning of the conveying belt. The material can still be stably carried, reducing material leakage and improving material utilization.

[0076] The stable anti-skid effect allows the conveying belt to adjust the running speed flexibly, thereby adjusting the material spreading thickness and cooling time, adapting to different brewing process requirements and solving the problem of poor process adaptability caused by the fixed speed of traditional plate chain conveying belts.

[0077] The food-grade silica gel material is soft, and the contact between the anti-skid convex points and the material is flexible, avoiding scratching or breaking the material and protecting the integrity of the material such as fermented grains, reducing impurities and being beneficial to subsequent fermentation and improving wine quality.

[0078] According to one embodiment of the present application, the anti-skid convex points are diamond-shaped anti-skid convex points.

[0079] In one embodiment of the present application, the anti-skid convex points adopt a diamond-shaped structure to further optimize the anti-skid effect and performance.

[0080] The anti-skid convex points are in a whole rhombus shape, and the corners are smoothly treated without sharp edges to avoid scratching the materials or workers. The long axis and short axis of the rhombus convex points are optimized to adapt to the particle characteristics of the materials, maximize the contact area and friction with the materials, and reduce the obstruction of the convex points to the airflow.

[0081] The rhombus anti-skid convex points are regularly arranged along the surface of the food-grade silica gel anti-skid functional layer 106, and the long axes of adjacent convex points are consistent to form a neat grid layout. The gap between the convex points forms a rhombus channel, which not only ensures the anti-skid effect, but also guides the airflow circulation, and facilitates the falling of material debris to avoid accumulation.

[0082] The rhombus structure makes the contact between the convex points and the materials multi-point contact, the contact area is uniform, the friction force is distributed reasonably, and the weight of the materials can be effectively dispersed to avoid deformation or adhesion of the materials caused by excessive local pressure. The smooth corners reduce the extrusion damage to the materials and protect the integrity of the materials.

[0083] The rhombus structure increases the contact area and friction between the convex points and the materials, and compared with other shapes such as circles, the anti-skid effect is better, which can effectively prevent the materials from sliding in various operating states, further reduce the material leakage phenomenon, and improve the stability of the conveying process.

[0084] The channels between the rhombus convex points facilitate the transverse and longitudinal circulation of the airflow, avoid excessive obstruction of the convex points to the airflow penetration, ensure that the cooling airflow can smoothly act on the bottom of the materials, do not affect the cooling efficiency, and realize the synergistic optimization of anti-skid and cooling.

[0085] The regular layout of the rhombus convex points and the smooth corners reduce the residue of the material debris, which is easy to fall from the gap between the convex points or be removed by the cleaning tool, reducing the cleaning difficulty, improving the hygiene and safety, and meeting the hygiene requirements of liquor brewing.

[0086] According to one embodiment of the present application, the height of the rhombus anti-skid convex points is 3mm.

[0087] In one embodiment of the present application, the height of the rhombus anti-skid convex points is precisely designed to balance the anti-skid effect and heat dissipation demand.

[0088] The height of the rhombus anti-skid convex points is optimized through experiments, which can ensure sufficient anti-skid effect without affecting the airflow circulation and material heat dissipation. The height of the convex points is consistent and uniformly distributed along the surface of the silica gel layer, ensuring that the support height between the materials and the silica gel layer is uniform, and avoiding local tilting of the materials.

[0089] The height of the convex points forms a certain gap between the materials and the surface of the silica gel layer, which increases the friction and accommodates the material debris and airflow, avoiding the sliding and poor heat dissipation caused by the direct adhesion of the materials to the silica gel layer. The height design adapts to the particle size of the materials to ensure that the convex points can effectively embed into the material gap and enhance the anti-skid effect.

[0090] The height of the convex points does not excessively obstruct the airflow channel. The gap between the material and the silica gel layer provides a flow space for the airflow. In combination with the longitudinal air guide channel, the cooling airflow can smoothly pass through the bottom of the material, achieving uniform cooling and avoiding airflow obstruction caused by excessively high convex points.

[0091] The height of the convex points can bear the weight of the material, avoiding deformation of the convex points due to excessive height or insufficient anti-slip effect due to insufficient height. The elasticity of the silica gel material cooperates with the height of the convex points, allowing the convex points to compress moderately when bearing the material, further enhancing the adhesion and friction with the material.

[0092] The precisely designed height of the convex points ensures sufficient anti-slip friction, effectively preventing material sliding, while reserving space for airflow, ensuring that the cooling effect is not affected. This solves the problem of poor heat dissipation caused by traditional anti-slip structures, improving the overall performance of the device.

[0093] The appropriate height of the convex points allows the material to be stably supported on the convex points, forming a stable stress state. Even when the conveyor belt is running quickly or frequently starting and stopping, the material is not easily tipped or spilled, reducing material loss and safety risks during transportation.

[0094] The height of the convex points forms a buffer space between the material and the silica gel layer, reducing direct friction and extrusion between the material and the conveyor belt, protecting the integrity of the material particles, avoiding breakage and impurities, which is beneficial to the subsequent fermentation process and improves the quality of the final product.

[0095] According to one embodiment of the present application, the steel belt conveying structure further comprises an air supply device arranged below the composite steel belt plate 102, which is used to provide cooling airflow from bottom to top.

[0096] In one embodiment of the present application, the steel belt conveying structure is additionally provided with an air supply device to provide stable cooling airflow for material airing.

[0097] The air supply device is arranged below the composite steel belt plate 102 and uniformly arranged along the length direction of the conveyor belt, ensuring that the entire conveying area can obtain uniform airflow supply. The air supply device includes a fan and an air guide cover. The air guide cover is in the shape of a horn with an opening facing upwards and aligned with the bottom of the composite steel belt plate 102, so that the airflow can be concentrated upwards, reducing diffusion loss.

[0098] After the air supply device is started, the cooling airflow generated by the fan is guided by the air guide cover and blows vertically upwards to the inner layer 104 of the ventilation punching of the composite steel belt plate 102. The airflow successively passes through the ventilation hole, the longitudinal air guide channel of the aluminum honeycomb composite heat dissipation layer, and finally penetrates the gap between the convex points of the food-grade silica gel anti-slip functional layer 106, acting on the bottom of the loaded material to remove heat from the material and achieve cooling.

[0099] The air supply device is linked with the running speed of the conveying belt, and the fan speed can be adjusted according to the material spreading thickness and cooling requirement to change the air flow intensity. When the material is thick or rapid cooling is required, the fan speed is increased to increase the air flow intensity; when the material is thin or the temperature is cooled to the target temperature, the speed is reduced to save energy consumption.

[0100] The number and layout of the air supply device are optimized according to the width and length of the conveying belt, the air flow coverage of adjacent fans overlaps each other to avoid air flow dead angle. The design of the air guide cover makes the air flow vertically upward, reduces the horizontal diffusion, and ensures that the air flow uniformly penetrates the composite steel belt plate 102 to realize uniform cooling of the material.

[0101] The directional and uniform air flow generated by the air supply device directly acts on the bottom of the material, cooperates with the air flow channel of the composite steel belt plate 102, quickly takes away the heat of the material, compared with natural ventilation or the ventilation mode of the conventional conveying belt, the cooling efficiency is significantly improved, the spreading time is shortened, and the production efficiency is improved.

[0102] The uniform distribution of the air flow enables each part of the material to be cooled with equal intensity, avoids uneven fermentation caused by local temperature difference, ensures uniform material temperature, is beneficial to stable microbial activity, and improves the final wine quality.

[0103] The second aspect embodiment of the present application provides a spreading equipment, which comprises the steel belt conveying structure as described above.

[0104] According to the second aspect of the present application, the three-layer composite design and continuous conveying mode of the steel belt conveying structure enable the material to be continuously subjected to airflow during movement, and the use of the aluminum honeycomb composite heat dissipation layer and the ventilation punched inner layer 104 ensures that the cooling airflow uniformly penetrates the material, avoiding the problem of insufficient local cooling in traditional spreading and airing equipment, greatly improving the spreading and airing efficiency, shortening the material cooling time, and meeting the process rhythm requirements of liquor brewing. The anti-slip design of the food-grade silica gel anti-slip function layer 106 and the jointless structure of the composite steel belt plate 102 effectively prevent the material from spilling or leaking out of the gap during conveying and spreading, reduce material loss, improve material utilization, reduce the production cost of liquor brewing, and solve the defect of serious material leakage of traditional plate chain conveying belts. The overall equipment has no sanitary dead angle, and the food-grade material and jointless design of the composite steel belt plate 102 reduce the residue of grain debris and fermented grains, reducing the risk of bacterial or mold growth. At the same time, the equipment is easy to clean and can quickly remove surface stains, meeting the hygiene standards of liquor brewing and ensuring the safety of the quality of the wine from the source. The driving device can adjust the running speed of the steel belt conveying structure, cooperate with the thickness adjustment of the feeding device, and flexibly adjust the material spreading and airing thickness and cooling time to adapt to the spreading and airing requirements of different types and batches of materials, solve the poor process adaptability problem caused by the fixed speed of traditional plate chain conveying belts, and improve the flexibility of the production process. The composite steel belt plate 102 of the steel belt conveying structure is made of corrosion-resistant and wear-resistant material, which can adapt to the humid and acidic working environment of liquor brewing and is not prone to aging and deformation. The firm connection of the chain 100 and the steel belt plate 102 reduces the probability of component loosening or damage, reduces the maintenance cost of frequent component replacement, and prolongs the overall service life of the equipment.

[0105] The spreading and airing equipment provided by the second aspect of the present application integrates the steel belt conveying structure and the adapted auxiliary components to achieve efficient and sanitary spreading and airing of liquor brewing materials.

The three-layer structure of the composite steel belt plate 102 works cooperatively: the ventilation punched inner layer 104 serves as a basic support, the aluminum honeycomb composite heat dissipation layer transfers heat and guides airflow, and the food-grade silica gel anti-skid functional layer 106 directly bears the material, and the layers are tightly connected to ensure that loosening or deformation does not occur during conveying.

[0108] The material is uniformly laid on the food-grade silica gel anti-skid functional layer 106 of the composite steel belt plate 102 through the feeding device, and the laying thickness can be controlled through the adjusting mechanism of the feeding device. The steel belt conveying structure moves along the length direction of the frame, and the material is cooled during the movement. The feeding end and the discharging end of the equipment are adaptively matched in height to ensure that the material is stably conveyed without accumulation or spilling, and the characteristics of the material such as liquor in the distillery are adapted.

[0109] The support structure of the frame avoids the material conveying area to reduce the sanitary dead angle. The surface of the composite steel belt plate 102 of the steel belt conveying structure is seamless, and the food-grade silica gel anti-skid functional layer 106 is not easy to leave residual material. After the equipment is stopped, the steel belt plate 102 can be directly cleaned without disassembly, and the cleaning method can adopt high-pressure water gun flushing or wiping, which is simple to operate. The bottom of the frame is provided with a sewage outlet to facilitate the discharge of cleaning wastewater and keep the surrounding environment clean.

[0110] According to one embodiment of the present application, the spreading and airing device further comprises an air supply device arranged below the steel belt conveying structure, and the cooling airflow generated by the air supply device sequentially passes through the ventilation punched inner layer 104 and the aluminum honeycomb composite heat dissipation layer of the steel belt conveying structure to cool the material borne on the anti-skid functional layer.

[0112] The air supply device is fixedly installed on the frame of the spreading and airing device and is located directly below the steel belt conveying structure and is arranged along the full length in the conveying direction to ensure that the material on the conveying belt can be continuously affected by the cooling airflow during the entire spreading and airing process. The air outlet of the air supply device is kept at a predetermined distance from the ventilation punched inner layer 104 of the steel belt conveying structure, so that the airflow can uniformly cover the entire width of the conveying belt without missing areas.
