Steaming treatment apparatus

Abstract

The utility model provides a kind of clear steaming treatment equipment, which includes a box, a conveyor belt and a steam passage. The multiple conveyor belts are arranged in a stacked manner inside the box, with the horizontal components of the conveying directions of the adjacent conveyor belts in opposite directions. The steam passage is located inside the conveyor belt, and the surface of the conveyor belt in contact with the material is provided with steam holes. By stacking the multiple conveyor belts, the conveying area is larger under certain floor space length conditions. The single and thick material layer can be divided into multiple thin material layers, which greatly reduces the resistance of the steam penetrating the material layer. The steam can quickly and uniformly act on all materials. This significantly shortens the steaming time, greatly improves the material processing capacity per unit time, and significantly improves the steaming efficiency.

Description

Technical Field

[0001] This utility model relates to the field of brewing, specifically to a steaming processing device. Background Technology

[0002] In the field of baijiu brewing, the main structure of the grain (such as rice husks, bran, etc.) steaming equipment commonly used in the brewing industry generally includes a rectangular steaming box and a horizontal conveyor belt, with steam pipes laid at the bottom or inside. During operation, the material is evenly spread on the horizontal conveyor belt to form a relatively thick layer, and then steam is introduced to complete the steaming within a set time.

[0003] However, existing steaming equipment still has the following two problems: 1. Low steaming efficiency: Due to the single-layer material layer structure, the material layer is relatively thick to meet the processing capacity requirements. This thick layer hinders the effective penetration and uniform distribution of steam, resulting in insufficient heating of the middle and lower layers. To ensure overall steaming effectiveness, the steaming time often needs to be extended, thereby reducing the equipment's processing capacity per unit time and affecting overall steaming efficiency.

[0004] 2. Uneven and incomplete steaming: In thicker layers of material, steam is prone to "short-circuiting," meaning it quickly escapes along areas with lower resistance (such as the edges or upper layers), while the center or bottom of the material layer cannot fully penetrate, easily forming "steaming dead zones." This results in some materials not being adequately cleaned of off-flavors and bacteria, affecting the quality stability of subsequent brewing processes. Utility Model Content

[0005] To address the above problems, this utility model provides a steaming treatment device with high processing capacity, thinner material layer, and more thorough steam penetration.

[0006] This utility model provides a steaming treatment device, which includes a housing, conveyor belts, and a steam channel. Multiple conveyor belts are arranged in a stacked manner inside the housing, with the horizontal components of the conveying directions of adjacent conveyor belts being opposite. The steam channel is located inside the conveyor belts, and steam holes are provided on the surfaces of the conveyor belts that contact the material.

[0007] According to the technical solution of this utility model, by using multi-layer conveyor belts stacked one on top of the other, a larger conveying area can be achieved within a certain floor space. This allows a single, thick material layer to be broken down into multiple thin layers, greatly reducing the resistance of steam penetration into the material layer. Steam can then act quickly and evenly on all materials. This significantly shortens the steaming time, greatly increases the material processing capacity (production capacity) per unit time, and significantly improves steaming efficiency.

[0008] Furthermore, the horizontal components of the conveying directions of adjacent conveyor belts are opposite, and the steam channel is directly located inside the conveyor belt. It directly contacts the material through steam holes opened on the surface of the conveyor belt. Thus, the material on the upper conveyor belt has surface A in contact with the conveyor belt and surface B away from the conveyor belt. When the material reaches the lower layer, it will be conveyed in an up-and-down flipping manner, that is, surface B in contact with the conveyor belt and surface A away from the conveyor belt. This allows the material to be steamed directly from the bottom layer upwards, and each surface of the material can receive sufficient and direct steam contact, avoiding steam dead zones and significantly improving the uniformity and thoroughness of steaming.

[0009] As a preferred technical solution of this utility model, the conveyor belt includes an input end, an output end and a middle section. Along the conveying direction of the conveyor belt, the material is conveyed from the input end of the conveyor belt to the output end of the conveyor belt. The middle section connects the input end and the output end, and the projection of the output end of the conveyor belt and the middle section of the conveyor belt adjacent below it overlaps in the horizontal direction.

[0010] According to this preferred technical solution, the projection of the output end of the conveyor belt onto the middle section of the adjacent conveyor belt below it in the horizontal direction overlaps, which allows the input end of the lower conveyor belt to receive the material from the output end of the upper conveyor belt, making the conveying process simpler and more efficient regardless of the connection structure between different conveyor belts.

[0011] As a preferred technical solution of this utility model, steam nozzles are evenly spaced along the conveying direction of the conveyor belt in the steam channel, and the steam nozzles are arranged facing the surface of the conveyor belt.

[0012] According to the preferred technical solution, the spaced steam nozzles ensure that steam can be discharged evenly from the steam holes, and the steam nozzles release steam upward toward the surface of the conveyor belt, which can further enhance the steam cleaning effect from bottom to top, so that the steam can more effectively and evenly contact the material layer, ensuring more uniform steam cleaning of the material.

[0013] As a preferred technical solution of this utility model, the steam channel is set inside the middle section of the conveyor belt, and the steam is transported in the same direction as the conveyor belt.

[0014] According to this preferred technical solution, the steam flows in the same direction as the conveyor belt within the channel, matching the dynamic distribution of steam release with the material's forward movement. This facilitates the formation of a stable and uniform steam coating layer on the material surface, avoiding localized steam accumulation or uneven distribution caused by intersecting flow directions. This improves heat exchange efficiency. Furthermore, the steam is directionally transported within the middle section of the conveyor belt and ejected upwards from the steam holes. Its flow path highly overlaps with the area of ​​material stably carried by the conveyor belt, maximizing the use of steam for material processing and reducing ineffective loss into the surrounding space, thus contributing to energy conservation and emission reduction.

[0015] As a preferred technical solution of this utility model, the housing has a material inlet and a material outlet. The material inlet is located above the middle section of the conveyor belt, and the material outlet is located below the output end of the conveyor belt. The housing also has a steam inlet and a steam outlet. The end of the steam passage near the input end of the conveyor belt is the steam input end, and the end of the steam passage near the output end of the conveyor belt is the steam output end. The steam inlet is connected to the steam input end, and the steam outlet is connected to the steam output end.

[0016] According to this preferred technical solution, on the one hand, the material inlet corresponds to the middle section of the uppermost conveyor belt, facilitating centralized feeding; the material outlet is located below the output end of the lowermost conveyor belt, allowing the material to fall naturally after multiple layers of conveying, eliminating the need for additional transfer mechanisms, and ensuring a clear and continuous overall material flow path. On the other hand, steam enters from the steam inlet at the input end of the conveyor belt, flows along the conveying direction through the entire steam channel, and exits from the steam outlet at the output end, synchronizing the steam distribution with the material's forward movement, which is beneficial for creating a stable and uniform steam environment on each layer of the conveyor belt.

[0017] As a preferred technical solution of this utility model, the steaming treatment equipment also includes a connecting channel, the first end of which is connected to the steam output end inside the upper conveyor belt, and the second end of which is connected to the steam input end inside the lower conveyor belt.

[0018] According to this preferred technical solution, the connecting channels enable the steam channels within each layer of the conveyor belt to be interconnected end-to-end, forming a complete steam transport loop within the housing and ensuring that the steam transport direction within each conveyor belt is consistent with the belt's transport direction. Thus, steam circulation can be controlled with only one steam inlet and one steam outlet, simplifying the pipeline design and increasing steam transport efficiency, thereby improving steaming efficiency.

[0019] As a preferred technical solution of this utility model, the conveyor belt is a chain plate type conveyor belt, and steam holes are formed between the drive chain plates of the chain plate type conveyor belt.

[0020] According to the preferred technical solution, the chain plate conveyor belt has high strength and good load-bearing capacity. The surface of the metal transmission chain plate is smooth and easy to clean, and it is not easy to breed bacteria. It is not easy to slip or stick to the conveyed wet materials, and it causes minimal physical damage to the materials. It can maintain the integrity and quality of the materials well. Multiple transmission chain plates can also form uniform steam holes, so that steam can pass through the transmission chain plate and come into more uniform and sufficient contact with the materials.

[0021] As a preferred technical solution of this utility model, the chain plate conveyor belt further includes: a drive motor, a drive shaft and a driven shaft. The output shaft of the drive motor is connected to the drive shaft for transmission. The drive shaft is connected to the driven shaft for transmission through the transmission chain plate. One end of the drive shaft passes through the side wall of the box. The drive motor is fixedly installed on the outside of the box.

[0022] According to this preferred technical solution, the drive motor is installed outside the housing, which can avoid the influence of steam on the motor and also prevent oil leakage from the drive motor from affecting the cleanliness of the materials.

[0023] As a preferred technical solution of this utility model, the steaming treatment equipment also includes a steam collection device, which is connected to the top of the box.

[0024] According to this preferred technical solution, by setting a steam collection device at the top of the box, the heat exchange steam can be discharged from the box in a timely manner, avoiding the steam from cooling and liquefying inside the box and causing water accumulation, which would affect the steaming effect of the material.

[0025] As a preferred technical solution of this utility model, the steam collection device includes a steam exhaust hood and a steam exhaust pipe. The steam exhaust hood is located above the housing and is connected to the housing; the steam exhaust pipe is located above the steam exhaust hood and is connected to the steam exhaust hood.

[0026] According to this preferred technical solution, the steam exhaust hood plays a role in collecting steam, and then the steam is discharged through the steam exhaust pipe, which further improves the efficiency of steam discharge from the box. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, "above" and "below" refer to the vertical arrangement relative to the direction of gravity, but do not directly limit the arrangement of two features in a vertically cumulative manner. The "above" or "below" of the first feature to the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "on top of," and "over" the first feature to the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the first feature to the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] First Embodiment Figure 1 This is a structural schematic diagram of a steaming processing device provided in an embodiment of this utility model. (See diagram below.) Figure 1 As shown, the first embodiment of this utility model provides a steaming treatment device, which mainly includes a box body 1, a conveyor belt 2 and a steam channel 3.

[0034] The housing 1 can be formed as a relatively closed hollow container, which is used to contain the conveyor belt 2, steam and materials. The housing 1 can be provided with a material inlet 11 and a material outlet 12 for receiving materials and discharging steamed materials. Furthermore, the housing 1 can also be provided with a steam inlet 13 and a steam outlet 14 for supplying hot steam into the housing 1 and recovering excess hot steam.

[0035] Two or more conveyor belts 2 are stacked vertically inside the housing 1. First, "multiple conveyor belts 2" can refer to two or more belts. The more conveyor belts 2 there are, the greater the material handling capacity of a single housing 1. Therefore, users can choose the number of conveyor belts 2 based on their actual needs. The following embodiment uses two conveyor belts 2 as an example. Using two conveyor belts 2 can increase material handling capacity while avoiding overly complex equipment structures and keeping costs relatively low.

[0036] The upper and lower conveyor belts 2 can be arranged parallel to each other or non-parallel, i.e., at a certain angle. Furthermore, the horizontal components of the conveying directions of adjacent upper and lower conveyor belts 2 are opposite; that is, the horizontal conveying directions of adjacent upper and lower conveyor belts 2 can be completely opposite. Figure 1 The conveying direction of the upper conveyor belt 2 is to the right, and the conveying direction of the lower conveyor belt 2 is to the left, or only the horizontal components are opposite, but the vertical components are not opposite, all of which fall within the protection scope of this utility model. The purpose of this arrangement is to enable the adjacent upper and lower conveyor belts 2 to transport materials back and forth. Thus, the material on the upper conveyor belt 2 has surface A in contact with conveyor belt 2 and surface B away from conveyor belt 2. When the material reaches the lower layer, it will be conveyed again by flipping up and down, that is, the surface in contact with conveyor belt 2 is B and the surface away from conveyor belt 2 is A.

[0037] Steam channel 3 is used for steam circulation. In this embodiment, it is worth mentioning that steam channel 3 is directly set inside conveyor belt 2. Steam in steam channel 3 can directly contact the material through steam holes opened on the surface of conveyor belt 2, so that steam can contact the bottom of the material and pass through the material upward for steaming.

[0038] In this embodiment, during operation, multiple stacked conveyor belts 2 continuously transport materials, breaking down a single, thick material layer into multiple thin layers as is common in existing technologies. Simultaneously, steam channels 3 introduce hot steam into each conveyor belt 2, cleaning the multiple thin material layers at the same time. This steaming equipment employs a method of simultaneously steaming multiple thin material layers, greatly reducing the resistance of steam penetration into the material. The steam can act quickly and evenly on all materials, significantly shortening the steaming time, greatly increasing the material processing capacity (production capacity) per unit time, and significantly improving the steaming efficiency.

[0039] Secondly, by tumbling and conveying the material between multiple conveyor belts 2, every side of the material can directly contact the steam for steaming. Furthermore, since the steam channel 3 is directly set inside the conveyor belt 2 and directly contacts the material through the steam holes opened on the surface of the conveyor belt 2, the steam can directly pass through the material from the bottom layer to steam the material, further avoiding steaming dead zones, and significantly improving the uniformity and thoroughness of steaming.

[0040] Second Embodiment The second embodiment of this utility model provides a more detailed structure of the steaming treatment equipment. Other features not mentioned or described are the same as those in the first embodiment and will not be repeated here.

[0041] Figure 2 This is a structural schematic diagram of a conveyor belt 2 provided by this utility model. Combined with... Figure 1 and Figure 2 As can be seen, the conveyor belt 2 may include an input end 21, an output end 22 and a middle section 23. Along the conveying direction of the conveyor belt 2, the material is conveyed from the input end 21 to the output end 22 of the conveyor belt 2. The middle section 23 is connected between the input end 21 and the output end 22. The output end 22 of the conveyor belt 2 and the middle section 23 of the conveyor belt 2 below it overlap in the horizontal direction.

[0042] According to the position arrangement of the upper and lower conveyor belts 2, the output end 22 of the conveyor belt 2 overlaps with the middle section 23 of the adjacent conveyor belt 2 below it in the horizontal direction. When conveying materials, the input end 21 of the lower conveyor belt 2 extends beyond the output end 22 of the upper conveyor belt 2 in the horizontal direction. The lower conveyor belt 2 can catch the materials conveyed by the upper conveyor belt 2, thereby completing continuous material conveying.

[0043] In some other embodiments, in order to enable the transfer and continuous conveying of materials between the upper and lower conveyor belts 2, a material guiding structure, such as a funnel or chute, can be set between the upper and lower adjacent conveyor belts 2. This allows the material to fall from the upper conveyor belt 2 into the lower conveyor belt 2 to complete the continuous conveying.

[0044] To ensure a more continuous flow of materials within the housing 1, the material inlet 11 of the housing 1 can be positioned above the middle section 23 of the conveyor belt 2 (i.e., above the middle section 23 of the uppermost layer of the conveyor belt 2 in the diagram), and the material outlet 12 can be positioned below the output end 22 of the conveyor belt 2 (i.e., below the middle section 23 of the uppermost layer of the conveyor belt 2). Figure 1(Below the output end 22 of the lowest layer conveyor belt 2). This allows the material to enter the housing 1 from the material inlet 11 and fall directly into the input end 21 of the uppermost conveyor belt 2, and then be continuously conveyed to the output end 22 of the lowest layer conveyor belt 2, finally exiting from the material outlet 12. This allows the material to pass through each conveyor belt 2 in sequence. This maximizes the utilization of the conveying area of ​​the conveyor belt 2 and further increases the material cleaning and steaming capacity per unit time.

[0045] Preferably, the steam channel 3 is located inside the middle section 23 of the conveyor belt 2, and the steam is transported in the same direction as the conveyor belt 2 within the steam channel 3. More preferably, steam nozzles 31 are evenly spaced along the conveyor belt 2 within the steam channel 3, and the steam nozzles 31 are positioned facing the surface of the conveyor belt 2. The spacing between the steam nozzles 31 can be flexibly adjusted according to actual needs to ensure that the material within each conveying distance can come into contact with sufficient steam.

[0046] Through the above methods, since the steam travels along the same direction as the conveyor belt 2 within the steam channel 3, the material can continuously exchange heat with the steam throughout the entire conveying process. This ensures that the material is fully heated throughout the entire conveying process, further improving the heat exchange efficiency between the hot steam and the material. Furthermore, the spaced steam nozzles 31 ensure that the steam can be discharged evenly, and the steam nozzles 31 release steam upwards toward the surface of the conveyor belt 2, which can guide the steam to directly steam the material from bottom to top, allowing the steam to fully and evenly contact the material layer, achieving a better steaming effect, fully removing impurities and bacteria from the material, and ensuring the quality of subsequent brewing.

[0047] In this design, the end of the steam channel 3 closest to the input end 21 of the conveyor belt 2 is the steam input end 21, and the end of the steam channel 3 closest to the output end 22 of the conveyor belt 2 is the steam output end 22. The steam inlet 13 is connected to the steam input end 21, and the steam outlet 14 is connected to the steam output end 22. The steam inlet 13 and the steam outlet 14 can be connected to an external hot steam conveying device via pipelines, allowing steam to continuously enter from the steam inlet 13, be released through the steam channel 3, and then be discharged from the steam outlet 14 to remove any steam that did not enter the housing 1, thus achieving cyclical hot steam conveying. Furthermore, the steam enters from the steam inlet 13 at the input end 21 of the conveyor belt 2, flows along the conveying direction through the entire steam channel 3, and is discharged from the steam outlet 14 at the output end 22, ensuring that the steam distribution is synchronized with the material's forward movement, which is beneficial for creating a stable and uniform steam environment on each layer of the conveyor belt 2.

[0048] Meanwhile, the steam channel 3 may also include a connecting channel 32, the first end of which is connected to the steam output end 22 inside the upper layer conveyor belt 2, and the second end of which is connected to the steam input end 21 inside the lower layer conveyor belt 2.

[0049] Through the above method, the connecting channel 32 connects the steam channels 3 inside each layer of conveyor belt 2, forming a complete steam conveying loop between each layer of conveyor belt 2 inside the housing 1. This ensures that the steam conveying direction within each conveyor belt 2 is consistent with the conveying direction of the conveyor belt 2. Therefore, the steam circulation can be controlled by only one steam inlet 13 and one steam outlet 14, simplifying the pipeline design and increasing steam conveying efficiency, thus improving steaming efficiency.

[0050] Third Embodiment The third embodiment of this utility model provides a more specific conveyor belt 2 structure. Other features not mentioned or described are the same as those in the first and / or second embodiments, and will not be repeated here.

[0051] In this embodiment of the steaming treatment equipment, the conveyor belt 2 is a chain plate type conveyor belt 2, and steam holes are formed between the drive chain plates 24 of the chain plate type conveyor belt 2. Multiple drive chain plates 24 can also directly form uniform steam holes, allowing steam to pass through the drive chain plates 24 and make more even and sufficient contact with the material. Compared with other conveyor belt structures 2, the structure of multiple drive chain plates 24 spliced ​​together in the chain plate type conveyor belt 2 is more conducive to drilling and grooving, and is less prone to steam corrosion and cracking, making it more durable.

[0052] Furthermore, the chain conveyor belt 2 may also include: a drive motor 25, a drive shaft 26, and a driven shaft 27. The output shaft of the drive motor 25 is connected to the drive shaft 26, and the drive shaft 26 is connected to the driven shaft 27 via a transmission chain 24. One end of the drive shaft 26 passes through the side wall of the housing 1, and the drive motor 25 is fixedly installed on the outside of the housing 1. More specifically, as shown... Figure 1 The steaming equipment described above has two chain conveyor belts 2 installed inside the housing 1. The drive motor 25 of one conveyor belt 2 is installed at the top of the housing 1, and the drive motor 25 of the other conveyor belt 2 is installed at the bottom of the housing 1. Installing the drive motor 25 outside the housing 1 can avoid the influence of steam on the motor and also prevent oil leakage from the drive motor 25 from affecting the cleanliness of the materials.

[0053] By adopting the above methods, the chain plate conveyor belt 2 has advantages such as high strength and good load-bearing capacity, making it more suitable for conveying heavier wet materials. In addition, the metal transmission chain plate 24 has a smooth surface that is easy to clean and does not easily breed bacteria. It is not easy for wet materials to slip or stick, and the physical damage to the materials is minimal, which can well maintain the integrity and quality of the materials.

[0054] Of course, the conveyor belt 2 is not limited to the chain plate type conveyor belt 2. In some other embodiments, the conveyor belt 2 can also be other conveying equipment such as belt conveyor belt 2.

[0055] Fourth embodiment The fourth embodiment of this utility model provides a steaming treatment device with a steam collection device 4. Other features not mentioned or described are the same as those in the previous embodiments and will not be repeated here.

[0056] Since the temperature of the steam decreases after heat exchange with the material, if it is not discharged in time, it will affect the continuous entry of new steam into the chamber 1, thus affecting the steaming effect. Therefore, in this embodiment, the steaming treatment equipment also includes a steam collection device 4, which is connected to the top of the chamber 1.

[0057] By setting up a steam collection device 4, the cooled steam after heat exchange can be discharged from the box 1 in a timely manner, avoiding the steam from cooling and liquefying in the box 1 and causing water accumulation, which would affect the steaming effect of the material.

[0058] This embodiment also provides a preferred technical solution for the steam collection device 4. Specifically, the steam collection device 4 includes a steam exhaust hood 41 and a steam exhaust pipe 42. The steam exhaust hood 41 is located above the housing 1 and communicates with the housing 1; the steam exhaust pipe 42 is located above the steam exhaust hood 41 and communicates with the steam exhaust hood 41.

[0059] According to the steam collection device 4, the steam exhaust hood 41 plays the role of collecting steam, and then the steam is discharged through the steam exhaust pipe 42, thereby further improving the efficiency of steam discharge from the box 1.

[0060] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
