Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a bean curd skin processing and drying device. Background Technology

[0002] Soybeans are a common edible legume in daily life, rich in nutrients. Soybeans are widely processed into various soy products, such as tofu, soy milk, bean curd sheets, and dried bean curd sticks. Among these, bean curd sheets are particularly popular due to their unique texture and flavor, especially products like Shiping bean curd sheets and spicy hot pot bean curd sheets.

[0003] The production process of bean curd sheets involves multiple steps, including selecting beans, peeling, soaking, grinding, filtering, boiling, forming a film, peeling, drying, boiling again, coating, drying, cooling, and packaging. Among these steps, the drying process is particularly crucial. The degree and quality of drying directly affect the shelf life of the bean curd sheets. If the bean curd sheets need to be stored for a long time, improper drying can easily lead to mold and spoilage, affecting product quality.

[0004] However, existing drying equipment has certain limitations in practical applications. Due to the limited airflow coverage area, the hot airflow is difficult to evenly cover the surface of the bean curd skin, resulting in poor drying effect. Utility Model Content

[0005] In view of this, the present invention aims to provide a bean curd skin processing and drying device that can improve the drying quality of bean curd skin.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] It includes a housing, as well as a conveying mechanism and a hot air supply mechanism located inside the housing;

[0008] The conveying mechanism includes multiple conveying sections arranged in a staggered manner along the height direction of the box, with adjacent conveying sections having opposite conveying directions;

[0009] The hot air supply mechanism includes a blower assembly disposed inside the housing, an air collecting pipe disposed outside the housing that connects the blower assembly and the air collecting hole, and an exhaust fan and a hot air fan connected in series with the air collecting pipe.

[0010] The air blowing pipe assembly is provided in a one-to-one correspondence with each of the conveying parts, and the air blowing pipe assembly is located above the conveying part.

[0011] Furthermore, the blower assembly includes a plurality of blowers spaced apart along the conveying direction of the conveying section, each blower extending along the depth direction of the housing, and a guide shroud and an air outlet located inside the guide shroud are provided at the bottom of each blower.

[0012] Furthermore, the cross-section of the air guide gradually increases in the direction away from the air blower; and / or, the air outlets are a plurality of those spaced apart along the axial direction of the air blower.

[0013] Furthermore, the outlet end of the flow guide is provided with a flow guide plate assembly, which divides the outlet of the flow guide into multiple ports.

[0014] Furthermore, the deflector assembly includes two deflectors arranged in a figure-eight shape; and / or, the deflector assembly consists of multiple deflectors nested sequentially inside and outside the air guide shroud.

[0015] Furthermore, one side of the box is provided with an outlet communicating with its interior, and the bottommost conveying part has an extension that extends out of the outlet, the extension being used to output the bean curd skin.

[0016] Furthermore, it also includes a cooling mechanism located on the outside of the housing, which is positioned above the extended portion and is used to cool the output bean curd sheets.

[0017] Furthermore, the air-cooling mechanism includes a bracket mounted on the housing and a fan mounted on the bracket; the bracket is arranged across the extended portion, and the fan is located above the extended portion.

[0018] Furthermore, the top of the box is provided with a feed inlet communicating with its interior, and the feed inlet is correspondingly arranged with the topmost conveying section.

[0019] Furthermore, the enclosure includes a main body with a drying chamber and a shielding door located on one side of the main body; the conveying mechanism and the blowing pipe are both located in the drying chamber; and / or, the shielding door is provided with an observation window.

[0020] Compared with the prior art, this utility model has the following advantages:

[0021] The bean curd skin processing and drying device of this utility model has multiple conveying sections arranged staggered along the height of the box and with adjacent conveying directions opposite, and an air blowing pipe assembly corresponding to each conveying section is set above the conveying section, as well as a hot air supply mechanism to provide hot air to the air blowing pipe assembly. In this way, the contact area between the hot air and the bean curd skin can be increased, thereby improving the drying quality of the bean curd skin.

[0022] The air blowing duct assembly includes multiple air blowing ducts spaced apart along the conveying direction of the conveying section, and the air blowing ducts are arranged along the depth direction of the box. A guide hood is set at the bottom of the air blowing duct, and an air outlet is set inside the guide hood. This ensures that the airflow covers the entire width of the conveying section, and can deliver the airflow to the bean skin on the conveying section in a better way, avoiding the problem of insufficient airflow in local areas. At the same time, the design of the guide hood can guide the airflow direction, making it sprayed more evenly. The air outlet is located inside the guide hood, which can prevent the airflow from generating turbulence or dispersion at the outlet of the air blowing duct, thereby improving the stability of the airflow.

[0023] The cross-sectional area of ​​the air guide gradually increases away from the air blowing pipe, and the air blowing pipe assembly includes multiple air blowing pipes spaced apart along the conveying direction of the conveying section. This design can guide the airflow to gradually diffuse, making the airflow coverage wider and avoiding the problem of excessively concentrated airflow causing local over-strength or under-strength, which helps to evenly distribute the airflow to the conveying section. In addition, multiple spaced air outlets can ensure that the airflow is evenly distributed in the entire width direction of the conveying section, avoiding the problem of uneven airflow caused by the limited coverage of a single air blowing pipe.

[0024] A guide plate assembly is installed at the outlet end of the guide hood, dividing the outlet of the guide hood into multiple outlets. This allows the airflow to cover the conveying section more evenly, avoiding the problem of concentrated or uneven airflow caused by a single outlet, reducing dead zones in the conveying section, and ensuring that the bean curd skin in each area is fully dried. The uniform airflow distribution can ensure the stability of the bean curd skin in the conveying section, preventing the bean curd skin on the conveying section from being blown away by excessive local airflow, thereby reducing losses.

[0025] The baffle assembly includes baffles arranged in a figure-eight shape, and multiple baffle assemblies are nested inside and outside the air guide hood. This can evenly distribute the airflow entering the air guide hood to all directions, further increase the coverage area of ​​the airflow, reduce dead corners of the airflow in the conveying section, and thus help improve the drying effect.

[0026] An outlet connected to the interior is opened on one side of the box, and the bottom conveyor section has an extension that goes through the outlet. In this way, the bean curd sheets can be automatically output from the box through the extension of the conveyor section, improving production efficiency. In addition, the extension can be easily connected to other production equipment, so as to flexibly adapt to different production line layouts, thereby improving the automation level of the entire production line.

[0027] An air-cooling mechanism is installed on the outside of the housing to cool the output bean curd sheets. This mechanism can quickly reduce the temperature of the bean curd sheets and shorten the cooling time. At the same time, the air-cooling mechanism works in conjunction with the extended part of the conveying section to achieve automated cooling, reduce manual intervention, and improve the automation level of production, thereby improving the production efficiency of the entire bean curd sheet processing and drying device. In addition, integrating the air-cooling mechanism into the bean curd sheet processing and drying equipment makes the equipment more compact, thereby reducing the equipment footprint and improving the flexibility of equipment layout.

[0028] The air-cooling mechanism includes a bracket mounted on the housing and a fan mounted on the bracket. The bracket spans the extended portion, and the fan is positioned above the extended portion. This spanning of the bracket ensures that the fan's airflow evenly covers the entire width of the extended portion, allowing the airflow generated by the fan to directly act on the bean curd skins on the extended portion, accelerating the heat dissipation process, improving cooling efficiency, and avoiding localized insufficient cooling. Furthermore, the bracket on the housing provides reliable support, enhancing the stability of the air-cooling mechanism. A feed inlet is located at the top of the housing, corresponding to the topmost conveyor section. This facilitates the even and rapid entry of bean curd skins into the conveyor section, and the simple structure helps reduce manufacturing costs.

[0029] A drying chamber is set up, with the conveyor mechanism located inside. A shielded door with an observation window is installed on one side of the drying chamber. This creates a closed space that concentrates heat, ensuring sufficient contact between hot air and the material, thus improving drying efficiency. Furthermore, the shielded door prevents operators from directly contacting the high-temperature drying chamber or air ducts during operation, enhancing equipment safety. The observation window allows operators to monitor the drying process in real time without opening the shielded door, preventing heat loss or affecting drying results due to frequent door opening and closing. The shielded door also facilitates regular maintenance and cleaning of the components inside the drying chamber. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0048] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] Existing drying equipment has certain limitations in practical applications. Due to the limited airflow coverage area, the hot airflow cannot evenly cover the surface of the bean curd sheets during drying, resulting in poor drying effect. In view of this, the present invention aims to propose a bean curd sheet processing and drying device to improve the drying quality of bean curd sheets.

[0050] In terms of overall structure, such as Figures 1 to 3 As shown, the bean curd skin processing and drying equipment of this embodiment includes a housing 1, a conveying mechanism 2 and a hot air supply mechanism 3 disposed within the housing 1. The conveying mechanism 2 includes multiple conveying sections arranged in a staggered manner along the height direction of the housing 1, with adjacent conveying sections conveying in opposite directions. The hot air supply mechanism 3 includes an air blowing pipe assembly disposed within the housing 1, an air collecting pipe 34 disposed outside the housing 1 connecting the air blowing pipe assembly, and an exhaust fan 35 and a hot air fan 36 connected in series on the air collecting pipe 34. The air blowing pipe assembly is arranged one-to-one with each conveying section, and the air blowing pipe assembly is disposed above the conveying section. The advantage of this arrangement is that it allows hot air to evenly cover each conveying section, improving the drying quality of the bean curd skin. The staggered arrangement means that the projections of each conveying section in the height direction of the housing do not completely overlap. Specifically, the rightmost end of the topmost conveying section does not exceed the rightmost end of the middle conveying section, and the leftmost end of the bottommost conveying section exceeds the leftmost end of the middle conveying section. This arrangement allows the conveying units to be arranged in a staggered pattern inside the housing, thereby optimizing space utilization and improving production efficiency.

[0051] In addition, in specific implementation, each conveying unit has a conveyor belt 21 for conveying bean curd sheets. The conveyor belt 21 includes a driving pulley, a driven pulley and a transmission belt body sleeved on the driving pulley and the driven pulley, which are mounted on the housing 1.

[0052] Furthermore, it is worth mentioning that, in this embodiment, an air collection hole 33 is further provided on the top surface of the housing 1. An air collection pipe 34 is connected to the air collection hole 33, and a dehumidifier 38, a mixing chamber 37, and an air filter 39 can be connected in series on the air collection pipe 34. The structures of the dehumidifier 38 and the air filter 39 can refer to existing technologies. In actual operation, after hot air is blown out through the air blower 31, it passes through the air collection hole 33 on the top surface of the housing 1 and the air collection pipe 34 connected to the air collection hole 33. A fan 35 connected in series on the air collection pipe 34 then guides the hot air into the dehumidifier 38. Subsequently, the hot air dried in the dehumidifier 38 mixes with the fresh air entering the mixing chamber 37, thereby increasing the intake air temperature and reducing energy consumption. The mixed air will pass through the air filter 39 to remove impurities. Then, the clean air will be drawn into the hot air blower 36, heated to a predetermined temperature, and then introduced into the blower pipe 31 and sprayed into the housing 1.

[0053] Of course, any related structures not mentioned in the bean curd skin processing and drying device of this embodiment, such as the exhaust fan 35 and the hot air blower 36, can be referred to the structures in related products familiar to those skilled in the art.

[0054] In this embodiment, as a preferred implementation, such as Figure 3 As shown, the air blowing pipe assembly includes multiple air blowing pipes 31 spaced apart along the conveying direction of the conveying section. Each air blowing pipe 31 extends along the depth direction of the housing 1, and a guide shroud 311 and an air outlet 312 located within the guide shroud 311 are provided at the bottom of each air blowing pipe 31. This ensures that the airflow covers the entire width of the conveying section, increases the contact area between the hot air and the bean curd skin, and avoids the problem of insufficient airflow in local areas. At the same time, the guide shroud 311 can guide the airflow direction, making it sprayed more evenly. By placing the air outlet 312 within the guide shroud 311, turbulence or dispersion of the airflow at the outlet 12 of the air blowing pipe 31 can be avoided, thereby improving the stability of the airflow.

[0055] Furthermore, in specific implementation, the air guide 311 and each air blowing pipe 31 are connected by welding. This ensures that the air guide 311 and the air blowing pipe 31 will not loosen or fall off due to vibration, airflow impact or mechanical stress during long-term use, while achieving good sealing performance and preventing airflow leakage. In the specific manufacturing process, both the air guide 311 and the air blowing pipe 31 are made of stainless steel well known to those skilled in the art, such as 304 stainless steel or 316 stainless steel, which will not be elaborated here.

[0056] In this embodiment, as a preferred implementation, such as Figure 5 and Figure 6 As shown, the cross-section of the guide shroud 311 gradually increases in the direction away from the air duct 31, and the air outlets 312 are multiple and spaced apart along the axial direction of the air duct 31. This allows the airflow to cover the conveying section more evenly, avoiding problems of concentrated or uneven airflow caused by a single outlet 12, reducing dead zones in the conveying section, ensuring that the bean curd skin in each area is fully dried, and ensuring the stability of the bean curd skin on the conveying section by the uniform airflow distribution, preventing the bean curd skin on the conveying section from being blown away due to excessively strong local airflow.

[0057] like Figure 5 and Figure 7 As shown, in this embodiment, as a preferred implementation, the outlet 12 end of the flow guide hood 311 is provided with a flow guide plate assembly 32, which divides the outlet 12 of the flow guide hood 311 into multiple openings. This arrangement allows the airflow to cover the conveying section more evenly, avoiding the problem of concentrated or uneven airflow caused by a single outlet 12, reducing dead zones in the conveying section, and ensuring that the bean curd skin in each area is fully dried.

[0058] In specific implementation, to be detailed, such as Figures 5 to 7 As shown, the air guide shroud 311 has a first connecting flange 313 on both sides along the axial direction of the air blower 31. The connecting flange has a first insertion hole 314. The air guide plate assembly 32 has a second connecting flange 322 corresponding to the first connecting flange 313. The second connecting flange 322 has a second insertion hole 323. Both the first insertion hole 314 and the second insertion hole 323 are multiple in number arranged along the axial direction of the air blower 31. Fasteners 315 are inserted into each first insertion hole 314 and the corresponding second insertion hole 323. In this embodiment, the fasteners 315 can be bolts and nuts well known to those skilled in the art.

[0059] In this embodiment, as a preferred implementation, such as Figure 8 As shown, the guide vane assembly 32 includes two guide vanes 321 arranged in a figure-eight shape, and the guide vane assembly 32 consists of multiple vanes nested inside and outside the air guide hood. This arrangement can evenly distribute the airflow entering the air guide hood to all directions, further increasing the coverage area of ​​the airflow, reducing dead zones in the airflow conveying section, and thus improving the drying effect.

[0060] In this embodiment, as a preferred implementation, such as Figure 1 , Figure 3 and Figure 4As shown, one side of the housing 1 has an outlet 12 communicating with its interior. The bottommost conveying section has an extension that extends out of the outlet 12, which is used to output the bean curd sheets. With this configuration, the bean curd sheets can be automatically output from the housing 1 via the extension of the conveying section, improving production efficiency. The extension can also be easily connected to other production equipment, thus flexibly adapting to different production line layouts and improving the overall automation level of the production line. Furthermore, in a specific implementation, the outlet 12 of the housing 1 is located at the bottom of the side wall of the housing 1, corresponding to the bottommost conveying section.

[0061] Similarly, continue as Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, as a preferred implementation, it also includes a cooling mechanism 4 located on the outside of the housing 1. The cooling mechanism 4 is positioned above the extended portion and is used to cool the output bean curd sheets. The advantage of this arrangement is that the cooling mechanism 4 can quickly reduce the temperature of the bean curd sheets, shortening the cooling time. The cooling mechanism 4, in conjunction with the extended portion of the conveying unit, enables automated cooling, reduces manual intervention, and improves the automation level of production, thereby increasing the overall production efficiency of the bean curd sheet processing and drying device. By integrating the cooling mechanism 4 into the bean curd sheet processing and drying equipment, the equipment becomes more compact, reducing the floor space required and increasing the flexibility of equipment layout.

[0062] In this embodiment, as a preferred implementation, such as Figure 4 As shown, the air-cooling mechanism 4 includes a bracket 41 mounted on the housing 1 and a fan 42 mounted on the bracket 41. The bracket 41 spans the extended portion, and the fan 42 is positioned above the extended portion. This arrangement, with the bracket 41 spanning the extended portion, ensures that the airflow from the fan 42 evenly covers the entire width of the extended portion. This allows the airflow generated by the fan 42 to directly act on the bean skin on the extended portion, accelerating the heat dissipation process of the bean skin, improving cooling efficiency, and avoiding the problem of insufficient localized cooling. The bracket 41 also provides additional support for the fan 42, enhancing the stability of the air-cooling mechanism 4.

[0063] In addition, in specific implementation, there can be multiple fans 42 mounted on the support 41. These multiple fans 42 are arranged along the width of the conveyor belt 21. In this way, while ensuring that the airflow evenly covers the entire width of the conveyor belt 21, the total amount of airflow can be increased, thereby improving cooling efficiency and shortening processing time.

[0064] In this embodiment, as a preferred implementation, the top of the housing 1 is provided with a feed inlet 13 communicating with its interior, and the feed inlet 13 is correspondingly arranged with the topmost conveying section. The advantage of this arrangement is that it facilitates the uniform and rapid entry of bean curd sheets into the conveying section, and the structure is simple, which helps to reduce manufacturing costs.

[0065] In this embodiment, as a preferred implementation, such as Figure 1 and Figure 3 As shown, the housing 1 includes a housing body with a drying chamber 11 and a shielding door 14 located on one side of the housing body. The conveying mechanism 2 and the air blowing pipe 31 are both located in the drying chamber 11. The shielding door 14 is provided with an observation window 141. This arrangement creates a closed space, concentrating heat and ensuring sufficient contact between hot air and materials, which is beneficial for improving drying efficiency. In addition, by setting the shielding door 14, operators can be prevented from directly contacting the high-temperature drying chamber 11 or the air blowing pipe 31 during equipment operation, which is beneficial for improving equipment safety. The setting of the observation window 141 allows operators to monitor the drying process in real time without opening the shielding door 14, avoiding heat loss or affecting the drying effect due to frequent opening and closing of the door. The setting of the shielding door 14 also makes the components inside the drying chamber 11, such as the drying mechanism and the air blowing pipe 31, easier to access, facilitating regular maintenance and cleaning.

[0066] In specific implementation, the observation window 141 can be made of quartz glass, which is well known to those skilled in the art, to ensure that the observation window 141 will not generate thermal stress cracks when subjected to a large temperature gradient. At the same time, quartz glass also has high chemical stability to ensure that the bean skin in the box 1 will not be contaminated.

[0067] In detail, in practical implementation, the conveyor belt 21 includes a first conveyor belt 211, a second conveyor belt 212, and a third conveyor belt 213 arranged sequentially from top to bottom. In actual operation, the moist bean curd sheets enter the box 1 through the feed inlet 13 located at the top of the box 1. The bean curd sheets fall onto the first conveyor belt 211, which transports the bean curd sheets from left to right. Hot air blown out from the blower pipe 31 is diffused through the guide hood 311 and the guide plate 321, continuously drying the bean curd sheets. Then, the bean curd sheets on the first conveyor belt 211 fall from the right end of the first conveyor belt 211 to the second conveyor belt 212 under the action of gravity.

[0068] The second conveyor belt 212 operates from right to left. Similarly, the bean curd sheets are continuously dried by hot air blown from the upper air duct 31 during the conveying process. The bean curd sheets on the second conveyor belt 212 also fall from the left end of the second conveyor belt 212 onto the third conveyor belt 213 by gravity. The third conveyor belt 213 operates from left to right. The hot air blown from the upper air duct 31 heats and dries the bean curd sheets on the third conveyor belt 213. The dried bean curd sheets are then conveyed out of the outlet 11 through the extended part of the third conveyor belt 213 and finally cooled by the fan 42 located above the extended part, thus completing the drying process.

[0069] The bean curd skin processing and drying device of this embodiment has multiple conveying sections arranged staggered along the height direction of the box 1 and with adjacent conveying directions opposite, and multiple air blowing pipes 31 corresponding to each conveying section above the conveying section. A guide hood 311 and a guide plate 321 are provided at the bottom of each air blowing pipe 31, and a hot air supply mechanism 3 provides hot air to the air blowing pipe 31. In this way, hot air can be evenly covered on each conveying section, thereby improving the drying quality of the bean curd skin.

[0070] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
