Description

Technical Field

[0001] This utility model relates to the field of vegetable dehydration technology, and in particular to a vegetable dehydration and drying device. Background Technology

[0002] Vegetable dehydration and drying is an important agricultural product processing technology that aims to remove most of the water from vegetables, inhibit microbial activity, extend shelf life, reduce transportation and storage costs, and at the same time preserve their color, nutrition and flavor as much as possible.

[0003] In related technologies, vegetable dehydration commonly employs hot air convection drying. This involves using a heater to raise the air temperature and a fan to force the hot air to circulate over the surface of the material, transferring heat to the vegetables through convection heat transfer while simultaneously removing the released moisture. However, for multi-layered stacked vegetable materials, hot air struggles to penetrate evenly and effectively to the bottom, resulting in inconsistent drying rates between different layers and even different parts of the same vegetable. Often, the surface vegetables are over-dried or even charred, while the bottom or inner vegetables retain a significant amount of moisture, severely impacting the overall quality of the dehydrated vegetable product. Manually turning the vegetables mid-process increases the cost of dehydration and reduces its efficiency.

[0004] Therefore, there is an urgent need for a vegetable dehydration and drying device that can automatically and evenly rotate vegetables to improve the quality and efficiency of dehydrated vegetable products. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a vegetable dehydration and drying device. This device can achieve automatic and uniform turning of vegetables, improving the quality and efficiency of dehydrated vegetable products.

[0006] The vegetable dehydration and drying device according to this utility model includes: case; A storage tube, wherein the storage tube is disposed inside the housing and the storage tube rotates about its axial direction; Multiple vegetable holding frames are disposed inside the storage tube, and the multiple vegetable holding frames are evenly distributed along the circumferential direction of the storage tube; A drive assembly is connected to the storage cylinder to drive the storage cylinder to perform equiangular intermittent indexing rotation; The air supply assembly includes at least an air supply port disposed opposite to one end of the storage cylinder and a return air port disposed opposite to the other end of the storage cylinder, wherein the air supply port and the return air port form a directional through-flow air path from the air supply port to the return air port in the axial direction of the storage cylinder. Each time the storage tube is indexed into position, one of the vegetable holding frames is aligned with the central axis of the air supply port. The different vegetable containers are positioned sequentially according to the index of the storage tube.

[0007] According to the vegetable dehydration and drying device provided in this embodiment, by setting up a shell, the shell can provide a closed working environment for vegetable dehydration, thereby ensuring the stability and safety of vegetable dehydration and simultaneously improving the product quality of dehydrated vegetables; by setting up a storage cylinder, multiple vegetable holding frames in the following embodiments can sequentially enter the optimal drying position aligned with the air supply port, and the vegetables in each vegetable holding frame can receive concentrated drying for the same duration and intensity, ensuring the uniformity of vegetable dehydration; by setting up a vegetable holding frame, all vegetables inside can be dried simultaneously, thereby significantly improving the vegetable dehydration efficiency. Uniformity and consistency are achieved through the design of the drive components. Each vegetable container can remain in the optimal drying position for the same amount of time, receiving stable and uniform hot air penetration. This ensures a high degree of consistency in the dehydration of different batches of vegetables, effectively improving the final quality of the dehydrated vegetable products. Furthermore, the air supply components create a directional airflow path along the axial direction of the storage cylinder, ensuring that the vegetables in the container are subjected to essentially uniform wind and heat. This significantly improves the uniformity of vegetable dehydration, preventing some vegetables from becoming over-dried while others retain moisture, greatly enhancing the quality of the finished dehydrated vegetables, and simultaneously increasing the efficiency of vegetable dehydration.

[0025] The following is for reference. Figures 1-5The vegetable dehydration and drying device according to an embodiment of the present invention includes: a housing 100; a storage cylinder 200 disposed inside the housing 100 and rotating about its axial direction; multiple vegetable receiving frames 300 disposed inside the storage cylinder 200 and evenly distributed along the circumferential direction of the storage cylinder 200; a driving assembly 400 connected to the storage cylinder 200 to drive the storage cylinder 200 to perform equiangular intermittent indexing rotation; and an air supply assembly. 500 includes at least an air supply port 510 disposed opposite to one end of the storage cylinder 200 and a return air port 520 disposed opposite to the other end of the storage cylinder 200. The air supply port 510 and the return air port 520 form a directional through-flow air path from the air supply port 510 to the return air port 520 in the axial direction of the storage cylinder 200. Each time the storage cylinder 200 is indexed into position, a vegetable receiving frame 300 is aligned with the central axis of the air supply port 510. Different vegetable receiving frames 300 are sequentially positioned as the storage cylinder 200 is indexed.

[0026] Specifically, the shell 100 can be constructed as a rectangular structure, a cylindrical structure, or other irregular structures; this embodiment of the invention does not impose specific limitations on this. The shell 100 can be constructed of a metallic material, such as stainless steel. Stainless steel has excellent corrosion resistance and lightweight characteristics, which can significantly extend the service life of the shell 100. The shell 100 provides a closed working environment for vegetable dehydration, thereby ensuring the stability and safety of vegetable dehydration and simultaneously improving the product quality of dehydrated vegetables.

[0027] The storage cylinder 200 can be constructed as a cylindrical structure, which facilitates smooth and stable movement when rotating around its axis, avoiding jamming during rotation. In the vegetable dehydration process, the storage cylinder 200 needs to be continuously filled with high-temperature gas, while the vegetables release a large amount of moisture, resulting in a continuous high-temperature and high-humidity environment inside the cylinder. The storage cylinder 200 can be constructed of 304 stainless steel, which has excellent corrosion resistance and high-temperature resistance, and a smooth surface that is easy to clean, thus ensuring the normal operation of the storage cylinder 200. By setting the storage cylinder 200, multiple vegetable receiving frames 300 in the following embodiments can sequentially enter the optimal drying position aligned with the air supply port 510, ensuring that the vegetables in each vegetable receiving frame 300 receive concentrated drying for the same duration and intensity, guaranteeing the uniformity of vegetable dehydration.

[0028] The vegetable holding frame 300 can be constructed as a hollow cylindrical structure, a rectangular strip structure, or a hollow polygonal strip structure. This embodiment of the invention does not specifically limit the shape; users can choose different shapes of vegetable holding frames 300 according to actual application scenarios. Multiple vegetable holding frames 300 can be evenly distributed along the circumference of the storage cylinder 200. The storage cylinder 200 can be fixedly installed inside the storage cylinder 200 by welding, snap-fit, or other connection methods, ensuring that the vegetable holding frames 300 and the storage cylinder 200 rotate in the same direction. It should be noted that the multiple vegetable holding frames 300 have the same structure and volume, thus ensuring the dynamic balance of the storage cylinder 200 during rotation and significantly improving the operational stability of the storage cylinder 200. This arrangement allows all vegetables inside each vegetable holding frame 300 to be dried simultaneously, thereby significantly improving the dehydration efficiency and uniformity of the vegetables.

[0029] The drive component 400 can be positioned on one side of the storage cylinder 200. The drive component 400 can drive the storage cylinder 200 to rotate at equal angles and intervals. That is, under the drive of the drive component 400, the storage cylinder 200 can rotate a fixed angle, stop for a period of time, and then rotate another fixed angle. This configuration ensures that each vegetable container 300 remains in the optimal drying position for the same amount of time, receiving stable and uniform hot air penetration, thus guaranteeing a high degree of consistency in the dehydration degree of different batches of vegetables and effectively improving the final quality of the dehydrated vegetable products.

[0030] It is important to note that the rotation angle of the storage cylinder 200 should correspond to the number of vegetable holding frames 300. For example, when there are 5 vegetable holding frames 300, the rotation angle of the storage cylinder 200 can be 72 degrees; when there are 6 vegetable holding frames 300, the rotation angle of the storage cylinder 200 can be 60 degrees. This arrangement ensures that after each rotation of the storage cylinder 200, each vegetable holding frame 300 can sequentially correspond to the air supply port 510 in the following embodiment, thereby ensuring that the high-temperature gas in the air supply port 510 can enter the vegetable holding frame 300.

[0031] The air supply assembly 500 can be located on one side of the housing 100, the air supply port 510 can be located at one end of the storage tube 200, and the return air port 520 can be located at the other end of the storage tube 200. It is important to note that the cross-sectional shapes of the air supply port 510 and the return air port 520 should match the cross-sectional shape of the vegetable storage frame 300. For example, if the cross-sectional shape of the vegetable storage frame 300 is cylindrical, the cross-sectional shapes of the air supply port 510 and the return air port 520 can also be cylindrical; if the cross-sectional shape of the vegetable storage frame 300 is rectangular, the cross-sectional shapes of the air supply port 510 and the return air port 520 should also be rectangular. This arrangement ensures that the high-temperature airflow blown from the air supply port 510 can evenly cover the entire cross-section of the vegetable storage frame 300, avoiding uneven airflow distribution caused by mismatched port shapes.

[0032] The air supply port 510 and the return air port 520 can form a directional through-flow air path in the axial direction of the storage cylinder 200, ensuring that the vegetables in the vegetable holding frame 300 are subjected to basically uniform wind and heat. This significantly improves the uniformity of vegetable dehydration, prevents some vegetables from being over-dried while others retain moisture, greatly improves the quality of the dehydrated vegetables, and simultaneously increases the efficiency of vegetable dehydration. The axial direction of the storage cylinder 200 can form a directional through-flow air path. Figure 2 The direction indicated by X in the middle.

[0033] It is important to note that each time the storage cylinder rotates 200 degrees to its final position, the central axis of the vegetable receiving frame 300 corresponding to the air supply port 510 coincides with the central axis of the air supply port 510. This arrangement ensures that the high-temperature airflow from the air supply port 510 is distributed most evenly across the cross-section of the vegetable receiving frame 300, avoiding eccentric airflow caused by axial deviation. This ensures a consistent environment for all vegetables within the frame, guaranteeing the quality of the dehydrated vegetables.

[0034] Driven by the drive assembly 400, different vegetable containers 300 sequentially reach the positions corresponding to the air supply port 510, thereby enabling the vegetables inside the vegetable containers 300 to automatically flip, ensuring that the high-temperature gas from the air supply port 510 evenly dries the vegetables inside the vegetable containers 300, thus improving the uniformity of vegetable drying.

[0035] According to the vegetable dehydration and drying device provided in this embodiment of the present invention, by setting up a shell 100, the shell 100 can provide a closed working environment for vegetable dehydration, thereby ensuring the stability and safety of vegetable dehydration and simultaneously improving the product quality of dehydrated vegetables; by setting up a storage cylinder 200, multiple vegetable holding frames 300 in the following embodiments can sequentially enter the optimal drying position aligned with the air supply port 510, and the vegetables in each vegetable holding frame 300 can obtain concentrated drying of the same duration and intensity, ensuring the uniformity of vegetable dehydration; by setting up a vegetable holding frame 300, all vegetables inside can be dried simultaneously, thereby significantly improving the dehydration quality of vegetables. Water efficiency and uniformity: By setting the drive component 400, each vegetable container 300 can stay in the optimal drying position for the same amount of time, receiving stable and uniform hot air penetration, thus ensuring a high degree of consistency in the dehydration degree of different batches of vegetables and effectively improving the final quality of dehydrated vegetable products; by setting the air supply component 500, a directional flow air path can be formed in the axial direction of the storage cylinder 200, ensuring that the vegetables in the vegetable container 300 are subjected to basically uniform wind and heat, thereby significantly improving the uniformity of vegetable dehydration, preventing some vegetables from being over-dried while others still retain moisture, greatly improving the quality of the finished dehydrated vegetables, and simultaneously improving the efficiency of vegetable dehydration.

[0036] Please continue reading Figures 2-4 As shown, drive shafts 210 are provided at both ends of the storage tube 200.

[0037] It should be noted that the drive shaft 210 can be fixedly installed at opposite axial ends of the storage cylinder 200 by welding or integral molding. The drive shaft 210 is supported on both sides of the housing 100 by high-precision rolling bearings 220 or sliding bearings 220. This two-end supported structure stably suspends the storage cylinder 200 inside the housing 100, allowing it to rotate smoothly around its own axis. This effectively avoids the deformation, vibration, or jamming problems of the drive shaft 210 caused by the huge cantilever torque that may be generated by single-point support, and greatly enhances the rigidity and stability of the storage cylinder 200.

[0038] Please continue reading Figures 2-4 As shown, according to one embodiment of the present invention, a bearing 220 is also provided at the other end of the storage tube 200. The outer ring of the bearing 220 is fixedly connected to the housing 100, and the inner ring of the bearing 220 is fixedly connected to the drive shaft 210.

[0039] Specifically, the outer ring of the bearing 220 can be press-fitted into the bearing 220 seat of the housing 100 using an interference fit, thereby achieving a fixed connection with the housing 100; the inner ring of the bearing 220 can be coaxially and fixedly connected to the drive shaft 210 using an interference fit or by adding a shaft retaining ring. This configuration allows for a rotatable connection between the storage cylinder 200 and the housing 100, significantly improving the rigidity and stability of the storage cylinder 200 during rotation, and effectively preventing deformation and vibration of the drive shaft 210.

[0040] Please continue reading Figures 2-4 As shown, according to another embodiment of the present invention, the plurality of storage tubes 200 include a first storage tube 230, a second storage tube 240 and a third storage tube 250 arranged along the height direction of the housing 100.

[0041] Specifically, there can be multiple storage cylinders 200, and these multiple storage cylinders 200 are stacked along the height direction of the housing 100. The height direction of the housing 100 can be... Figure 2 The direction indicated by Y in the diagram. In this embodiment, three are used as an example for explanation, but the number is not limited to three and can be adjusted according to actual capacity requirements. Multiple storage cylinders 200 can be vertically and evenly distributed along the height direction of the housing 100. The first storage cylinder 230 can be located at the inner bottom of the housing 100, the second storage cylinder 240 can be located above the first storage cylinder 230, and the third storage cylinder 250 can be located above the second storage cylinder 240, thereby significantly improving the space utilization rate inside the housing 100.

[0042] Please continue reading Figures 2-4 As shown, according to another embodiment of the present invention, the drive assembly 400 includes: a drive motor 410, which is fixedly connected to the housing 100; a drive wheel 420, which is coaxially fixedly connected to the shaft of the drive motor 410; a driven wheel 430, which is coaxially fixedly connected to the transmission shaft 210 of the first storage cylinder 230, and is drively connected to the drive wheel 420; and a first sprocket 440, which is disposed on one side of the driven wheel 430 and connected to the transmission shaft 210 of the first storage cylinder 230. 0. Coaxial fixed connection; Second sprocket 450, the second sprocket 450 is coaxially fixedly connected to one end of the drive shaft 210 of the second storage cylinder 240, and is connected to the first sprocket 440 through chain 480; Third sprocket 460, the third sprocket 460 is disposed on one side of the second sprocket 450, and is coaxially fixedly connected to the drive shaft 210 of the second storage cylinder 240; Fourth sprocket 470, the fourth sprocket 470 is coaxially fixedly connected to one end of the drive shaft 210 of the third storage cylinder 250, and is connected to the third sprocket 460 through chain 480.

[0043] Specifically, the drive motor 410 can be fixedly installed on the side of the housing 100 by means of bolt connection, and the drive motor 410 can provide driving force for the rotation of the storage cylinder 200.

[0044] Furthermore, the drive wheel 420 can be fixedly connected to the shaft of the drive motor 410 via a coaxial connection. With this configuration, the drive motor 410 can drive the drive wheel 420 to rotate.

[0045] The driven wheel 430 can be fixedly connected to the drive shaft 210 of the first storage cylinder 230 by means of coaxial connection. The driven wheel 430 can mesh with the drive wheel 420, which makes it easy for the drive wheel 420 to rotate and drive the driven wheel 430 to rotate, thereby driving the first storage cylinder 230 to rotate.

[0046] The first sprocket 440 can be fixedly connected to the drive shaft 210 of the first storage cylinder 230 via a coaxial connection and is located on one side of the driven wheel 430. With this configuration, when the driven wheel 430 drives the drive shaft 210 of the first storage cylinder 230 to rotate, it can synchronously drive the first sprocket 440 to rotate in the same direction.

[0047] The second sprocket 450 can be fixedly connected to the drive shaft 210 of the second storage cylinder 240 via a coaxial connection. The second sprocket 450 can also be connected to the first sprocket 440 via a chain 480. With this configuration, the first sprocket 440 can drive the second sprocket 450 to rotate synchronously, thereby ensuring the synchronous rotation of the second storage cylinder 240.

[0048] The third sprocket 460 can be fixedly connected to the drive shaft 210 of the second storage cylinder 240 via a coaxial connection and is located on one side of the second sprocket 450, thereby ensuring that the second sprocket 450 drives the third sprocket 460 to rotate synchronously.

[0049] The fourth sprocket 470 can be fixedly installed on the drive shaft 210 of the second storage cylinder 240 via a coaxial connection. The fourth sprocket 470 can be connected to the third sprocket 460 via a chain 480. With this configuration, the third sprocket 460 can drive the fourth sprocket 470 to rotate synchronously, thereby ensuring the synchronous rotation of the third storage cylinder 250.

[0050] By setting the drive component 400, the synchronous rotation of multiple storage cylinders 200 can be achieved, ensuring that the multiple storage cylinders 200 achieve equiangular intermittent indexing rotation under the drive motor 410. This allows the multiple storage cylinders 200 to rotate synchronously and precisely at the same preset angle each time during operation, and to pause synchronously. This setting can guarantee a high degree of consistency and uniformity in the vegetable dehydration process within different storage cylinders 200, significantly improving the practicality of the vegetable dehydration and drying device.

[0051] Please continue reading Figures 1-5 As shown, according to an optional embodiment of the present invention, a cover plate (not shown in the figure) is provided at the other end of the vegetable container 300. The cover plate is movably connected to the vegetable container 300, and the cover plate has a hollow structure.

[0052] Specifically, the cover can be constructed with a perforated structure to ensure that gas inside the vegetable container 300 can be released evenly from the cover. The cross-sectional shape of the cover should be consistent with the cross-sectional shape of the vegetable container 300. When the cover is closed, it can form a closed container space with the vegetable container 300. This effectively prevents vegetables from leaking out of the interface gaps during the rotation or intermittent indexing of the storage cylinder 200, thereby ensuring the operational safety and structural integrity of the vegetable container 300.

[0053] One side of the cover can be hinged to the vegetable container 300, allowing users to easily flip and open the cover for loading and unloading vegetables, greatly improving the ease of use of the device.

[0054] Please continue reading Figure 2 As shown, according to a further embodiment of the present invention, the air supply assembly 500 includes: a heating fan 530, which is disposed on one side of the housing 100; and an air supply pipe 540, one end of which is connected to the air outlet of the heating fan 530, and the other end of which is connected to the air supply port 510.

[0055] Specifically, the heating fan 530 can be fixedly installed on the outside of the housing 100 by bolt connection. The heating fan 530 can draw in ambient air, heat it to the set temperature by the internal heater, form a high temperature dry airflow, and send it out into the vegetable container 300 through the air supply port 510.

[0056] One end of the air supply pipe 540 can be connected to the air outlet of the heating fan 530 via a flange connection, and the other end of the air supply pipe 540 can be connected to the air supply port 510 via a flange connection. With this configuration, the high-temperature dry airflow generated by the heating fan 530 can be delivered to the air supply port 510 via the air supply pipe 540, and then evenly blown into the vegetable container 300 from the air supply port 510, thereby drying the vegetables in the vegetable container 300 and completing the dehydration process.

[0057] Please continue to refer to the figure. In one optional embodiment of this utility model, the vegetable dehydration and drying device further includes: a control panel 600. The control panel 600 is disposed on the outside of the housing 100. The control panel 600 is electrically connected to the drive motor 410 to control the speed of the drive motor 410.

[0058] Specifically, the control panel 600 can be bolted to the outside of the housing 100, and the control panel 600 can be electrically connected to the drive motor 410 via a wired connection. With this configuration, the control panel 600 can control the speed and running time of the drive motor 410, thereby enabling the storage cylinder 200 to rotate at equal angles and intervals.

[0059] Please continue reading Figure 5 As shown, in an optional embodiment of this utility model, the side wall of the vegetable container 300 is provided with a plurality of ventilation holes 310.

[0060] Specifically, the ventilation hole 310 can be constructed as a circle, a rectangle, or other irregular structures. This embodiment of the invention does not impose specific limitations on this; users can choose a suitable shape for the ventilation hole 310 according to the actual application scenario. It should be noted that the shape of the ventilation hole 310 should be smaller than the shape of the vegetable to prevent vegetables from leaking out of the ventilation hole 310 during the rotation of the vegetable holding frame 300. The ventilation holes 310 can be evenly distributed on the side walls of the vegetable holding frame 300, ensuring that vegetables in all positions within the vegetable holding frame 300 can fully contact the high-temperature airflow, avoiding quality problems such as localized drying or dampness of vegetables due to uneven ventilation, and greatly improving the uniformity of the dehydration effect.

[0061] Please continue reading Figure 2 As shown, in some examples of this utility model, the vegetable dehydration and drying device also includes a humidity sensor 700, which is disposed inside the housing 100 and is communicatively connected to the control panel 600.

[0062] Specifically, the humidity sensor 700 can be fixedly installed near the return air port 520 inside the housing 100 by bolt connection. The humidity sensor 700 can communicate with the control panel 600 via wired or wireless connection.
