Description

Technical Field

[0001] The present application relates to the technical field of vegetable drying, and in particular to a vegetable dehydration and drying device. Background Art

[0002] Dehydrated vegetables, also known as rehydrated vegetables, are made by washing, drying and other processes of fresh vegetables to remove most of the water in the vegetables. The original color and nutritional components of the vegetables remain basically unchanged. They are easy to store and transport, and can effectively regulate the peak and off-peak seasons of vegetable production. When eaten, just soak them in clean water to restore them, and retain the original color, nutrition and flavor of the vegetables. Drying is an essential process for making dehydrated vegetables.

[0003] Existing drying equipment has some shortcomings. First, the existing equipment dries vegetable slices from all sides, which makes it difficult to dry vegetable slices in the middle of the equipment, while vegetable slices on the periphery are easily over-dried, resulting in uneven drying. Secondly, during the drying process of the equipment, some vegetable slices need to be turned over, otherwise the upper and lower surfaces will be dried unevenly. Finally, existing drying equipment can usually only dry vegetable slices of one drying difficulty, and cannot meet the demand of drying vegetable slices of multiple drying difficulties at one time while ensuring the drying effect and not over-drying. Summary of the Invention

[0004] The present application proposes a vegetable dehydration and drying device, which has the advantage of uniform drying, and is used to solve the problem of existing equipment that vegetable slices in the middle are difficult to dry, while vegetable slices around are easily over-dried, resulting in uneven drying.

[0005] To achieve the above-mentioned object, the present application adopts the following technical solution: a vegetable dehydration and drying device, comprising a base, a shell fixedly connected to the upper portion of the base, a movable door movably installed on the front portion of the shell, a heating air machine fixedly connected to the interior of the base, a bottom shell fixedly connected to the upper surface of the heating air machine, and a middle portion of the bottom shell connected to the air outlet of the heating air machine;

[0006] Multiple discs, the lowest disc is clamped with the upper bottom shell, the bottom of the upper disc is adapted to the top of the lower disc, the bottom of the disc is provided with multiple through holes, the inner center of the disc is provided with a mounting hole, a rotating sleeve is rotatably installed inside the mounting hole, and the curved surface of the rotating sleeve is provided with multiple air outlet holes;

[0007] The top cover is connected to the uppermost disc. Two return air pipes are installed on the upper surface of the top cover. The bottom ends of the return air pipes are connected to the return air end of the heating machine. A rotating sleeve is rotatably installed in the middle of the top cover. The curved surface of the rotating sleeve is provided with multiple air outlet holes.

[0008] If the above structure is able to work, multiple discs are stacked between the bottom shell and the top cover, which can effectively prevent hot air from being discharged into the interior of the shell, and each layer has an air outlet to discharge hot air, drying the upper surface of the vegetable slices, and the hot air in the lower layer will flow upward through the through holes, and the hot air will dry the lower surface of the vegetable slices.

[0009] Preferably, a driving motor is fixedly mounted on the upper surface of the shell, and the bottom end of the driving motor output shaft is fixedly connected to a telescopic shaft, and the telescopic shaft can extend or shorten while transmitting the power of the driving motor, and the bottom end of the telescopic shaft is fixedly connected to the top of the rotating sleeve, and a limit block is provided between the bottom end of the rotating sleeve and two adjacent rotating sleeves, and the rotating sleeve is fixedly connected to the limit block below, and the remaining limit blocks are fixedly connected to the rotating sleeve above it, and the top of the rotating sleeve is fixedly connected to the limiting slot. The above structure can, when working, make the distance between the top cover and the bottom shell adjustable by the setting of the telescopic shaft. The invention can be adjusted so that the number of discs placed between the top cover and the bottom shell can be changed within a certain range; secondly, when multiple discs are stacked, the upper limit block is adapted to the lower limit groove to prevent the leakage of hot air inside the rotating sleeve, and when the driving motor is working, it will drive the telescopic shaft to rotate, and the telescopic shaft will drive the rotating sleeve to rotate. Since the limit block is adapted to the limit groove, the rotating sleeve can drive the multiple rotating sleeves below to rotate, while the discs, the bottom shell and the top cover will not rotate, so that the air discharge from the curved surface outlet of the rotating sleeve will periodically sweep over the vegetable slices laid flat on the layer of discs, further ensuring the uniformity of the vegetable slices during drying.

[0010] Preferably, a partition is fixedly connected to the top of the rotating sleeve, a sealing plate is provided in the middle of the partition, the upper surface of the sealing plate is fixedly connected to a large spring, the upper end of the large spring is fixedly connected to a fixed plate, the topmost fixed plate is fixedly connected to the inner wall of the rotating sleeve, the remaining fixed plates are fixedly connected to the rotating sleeve at the same horizontal position, and the interior of the bottommost rotating sleeve is fixedly connected to another fixed plate. The above structure can be in operation. Through the setting of the partition and the sealing plate, when hot air enters the lower rotating sleeve, the hot air has a certain pressure when entering the rotating sleeve, and the air pressure will push the sealing plate to move upward, so that the gas from the lower rotating sleeve will enter the interior of the upper rotating sleeve. At the same time, the hot air from the lower rotating sleeve still has a certain pressure, thereby further ensuring the amount of gas discharged from each layer of space, thereby ensuring that the vegetable slices are evenly dried.

The above structure can, when working, energize the electromagnet to adsorb the permanent magnet, so that the permanent magnet and the plug move close to the electromagnet, so that the air outlet can discharge hot air; secondly, energize the electromagnetic ring to repel the permanent magnet ring, so that the sealing plate will not be opened by the impact of the air pressure of the rotating sleeve below.

[0012] Preferably, the edge of the top cover is provided with a slider, the inner wall of the shell is provided with a slide rail, the slider is located inside the slide rail and can slide up and down along the slide rail. If the above structure can be used, the top cover can slide up and down along the slide rail during operation, and further ensure that the top cover will not be caught.

[0013] Preferably, the air return pipe is a hose and does not hinder the up and down movement of the top cover.

[0014] Preferably, the limiting block is adapted to the limiting groove.

[0016] Preferably, the number of the plug inside the same rotating sleeve and the number of the air outlet holes opened on its surface are equal, and the plug and the air outlet holes are at the same horizontal position.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention stacks a plurality of discs filled with vegetable slices together, the bottom disc is clamped with the bottom shell, and then the heater works, and the air outlet continuously supplies hot air. The hot air will enter the interior of the plurality of rotating sleeves and finally be discharged from the air outlet. Since the plurality of discs are stacked between the bottom shell and the top cover, the hot air is always in the multi-layer space formed by the bottom shell, the top cover and the plurality of discs, and hot air enters each layer of space, and the hot air in the lower space will flow upward through the through holes on the discs. In the process of rising hot air, the lower surface of the vegetable slices will be dried, and the hot air discharged from the air outlet of this layer will dry the upper surface of the vegetable slices, thereby solving the problem of the existing equipment that the vegetable slices in the middle are difficult to dry, and the vegetable slices on the surroundings are easily over-dried, resulting in uneven drying.

[0019] 2. The present invention can drive multiple rotating sleeves below to rotate through the rotating sleeve, so that the air discharged from the curved surface air outlet of the rotating sleeve will periodically sweep over the vegetable slices laid flat on the disc. Multiple discs are stacked between the bottom shell and the top cover, which can effectively prevent hot air from being discharged into the interior of the shell. Moreover, each layer has an air outlet to discharge hot air, which dries the upper surface of the vegetable slices. The hot air from the lower layer will flow upward through the through holes, and the hot air will dry the lower surface of the vegetable slices, further ensuring the uniformity of the vegetable slices during drying, thereby solving the problem that some vegetable slices need to be turned over during the drying process of the existing equipment, otherwise the upper and lower surfaces will be dried unevenly.

[0020] 3. The present invention spreads vegetable slices with different dehydration requirements or different dehydration difficulties on the inside of a disc, and stacks them up and down according to the dehydration difficulty, with the dehydration difficulty increasing from bottom to top. The bottom electromagnet is energized to attract the permanent magnet, so that the permanent magnet and the plug move close to the electromagnet, so that the air vents can discharge hot air, and the remaining air vents are in a closed state, and the top sealing plate is in a closed state. When the vegetable slices at the bottom are dehydrated and dried to a certain extent, the air vents in this layer are closed, and the air vents in the upper layer are opened. This process is repeated until the top air vents are opened, thereby drying and dehydrating the vegetable slices with different dehydration difficulties at the same time.

Between the top cover 12, the hot air is always in the multi-layer space formed by the bottom shell 6, the top cover 12, and the multiple discs 7, and hot air enters each layer of space, and the hot air in the lower layer will pass through the through holes 8 on the disc 7 and flow upward, and finally enter the return air pipe 13 and return to the interior of the heating machine 5. In the process of rising, the hot air will dry the lower surface of the vegetable slices, and the hot air discharged from the air outlet 11 of this layer will dry the upper surface of the vegetable slices, saving energy and drying the vegetable slices more efficiently.

[0037] It can be understood that multiple discs 7 are stacked between the bottom shell 6 and the top cover 12, which can effectively prevent hot air from being discharged into the interior of the shell 2, and each layer has an air outlet 11 to discharge hot air, drying the upper surface of the vegetable slices, and the hot air in the lower layer will flow upward through the through hole 8, and the hot air will dry the lower surface of the vegetable slices.

[0038] Among them, the upper surface of the shell 2 is fixedly mounted with a drive motor 4, and the bottom end of the output shaft of the drive motor 4 is fixedly connected with a telescopic shaft 15. The telescopic shaft 15 can extend or shorten while transmitting the power of the drive motor 4. The bottom end of the telescopic shaft 15 is fixedly connected to the top of the rotating sleeve 14. A limit block 16 is provided between the bottom end of the rotating sleeve 14 and the two adjacent rotating sleeves 10. The rotating sleeve 14 is fixedly connected to the limit block 16 below, and the remaining limit blocks 16 are fixedly connected to the rotating sleeve 10 above it. The top of the rotating sleeve 10 is fixedly connected to the limit slot 31.

[0039] The disclosed feed crushing device for breeding can adjust the distance between the top cover 12 and the bottom shell 6 by setting the telescopic shaft 15, so that the number of discs 7 placed between the top cover 12 and the bottom shell 6 can be changed within a certain range; secondly, when multiple discs 7 are stacked, the upper limit block 16 is adapted to the lower limit groove 31 to prevent the leakage of hot air inside the rotating sleeve 10, and when the driving motor 4 is working, it will drive the telescopic shaft 15 to rotate, and the telescopic shaft 15 will drive the rotating sleeve 14 to rotate. Since the limit block 16 is adapted to the limit groove 31, the rotating sleeve 14 can drive the multiple rotating sleeves 10 below to rotate, while the discs 7, the bottom shell 6 and the top cover 12 will not rotate, so that the air discharged from the curved surface air outlet 11 of the rotating sleeve 10 will periodically sweep over the vegetable slices laid flat on the layer of discs 7, further ensuring the uniformity of the vegetable slices during drying.

[0040] Among them, the top of the rotating sleeve 10 is fixedly connected to a partition 17, the middle of the partition 17 is provided with a sealing plate 18, the upper surface of the sealing plate 18 is fixedly connected to a large spring 19, the upper end of the large spring 19 is fixedly connected to a fixing plate 20, the topmost fixing plate 20 is fixedly connected to the inner wall of the rotating sleeve 14, and the remaining fixing plates 20 are fixedly connected to the rotating sleeve 10 at the same horizontal position, and another fixing plate 20 is fixedly connected to the interior of the bottom rotating sleeve 10;

[0041] The present invention discloses a feed crushing device for breeding. Through the arrangement of the partition 17 and the sealing plate 18, when hot air enters the lower rotating sleeve 10, the hot air has a certain pressure when entering the rotating sleeve 10, and the air pressure will push the sealing plate 18 to move upward, so that the gas in the lower rotating sleeve 10 will enter the interior of the upper rotating sleeve 10. At the same time, the hot air in the lower rotating sleeve 10 still has a certain pressure, thereby further ensuring the amount of gas discharged from each layer of space, thereby ensuring that the vegetable slices are evenly dried.

[0042] Among them, the lower part of the fixing plate 20 is fixedly connected to the mounting seat 21, and a plurality of mounting cavities 22 are opened inside the mounting cavity 22. An electromagnet 23 is fixedly installed inside the mounting cavity 22, and a small spring 24 is fixedly connected to the outer side of the electromagnet 23. The outer end of the small spring 24 is fixedly connected to the permanent magnet 25. The outer side of the permanent magnet 25 is fixedly connected to a plug 26. The outer end of the plug 26 is adapted to the air outlet 11. An electromagnetic ring 27 is fixedly installed below the uppermost mounting seat 21, and a permanent magnet ring 28 fixedly connected to the sealing plate 18 is provided below the electromagnetic ring 27.

[0043] The present invention discloses a feed crushing device for breeding, which attracts the permanent magnet 25 by energizing the electromagnet 23, so that the permanent magnet 25 and the plug 26 move closer to the electromagnet 23, thereby allowing the air outlet 11 to discharge hot air; secondly, the electromagnetic ring 27 is energized to repel the permanent magnet ring 28, so that the sealing plate 18 will not be opened by the impact of the air pressure of the rotating sleeve 10 below.

[0044] Among them, a slider 29 is provided on the edge of the top cover 12, and a slide rail 30 is provided on the inner wall of the shell 2. The slider 29 is located inside the slide rail 30 and can slide up and down along the slide rail 30. The return air pipe 13 is a hose and does not hinder the up and down movement of the top cover 12. The limit block 16 is adapted to the limit groove 31. The sealing plate 18 contacts the partition 17 below it under the push of the large spring 19. The number of plugs 26 inside the same rotating sleeve 10 is equal to the number of air outlets 11 opened on its surface, and the plug 26 and the air outlet 11 are in the same horizontal position. Its function is that the top cover 12 can slide up and down along the slide rail 30, and further ensure that the top cover 12 will not be grabbed.

[0045] The present embodiment provides a vegetable dehydration and drying device, which spreads vegetable slices with different dehydration requirements or different dehydration difficulties on the inside of the disc 7, and stacks them up and down according to the dehydration difficulty, with the dehydration difficulty increasing from bottom to top. The lowest electromagnet 23 is energized to attract the permanent magnet 25, so that the permanent magnet 25 and the plug 26 move close to the electromagnet 23, so that the air outlet 11 can discharge hot air, and the remaining air outlets 11 are in a closed state, and the electromagnetic ring 27 is energized to repel the permanent magnet ring 28, so that the sealing plate 18 will not be opened by the impact of the air pressure of the rotating sleeve 10 below. The hot air discharged from the lowest layer of air outlets 11 will slowly dehydrate and dry the vegetable slices of each layer when it flows upward. When the vegetable slices at the bottom are dehydrated and dried to a certain extent, the air outlet 11 of this layer is closed, and the air outlet 11 of the upper layer is opened. This process is repeated until the air outlet 11 at the top is opened, thereby drying and dehydrating the vegetable slices of different dehydration difficulties at the same time.

[0046] Working principle:

[0047] The movable door 3 is opened, and the vegetable slices to be dried are spread flat on the inside of the disc 7, and multiple discs 7 with vegetable slices are stacked up and down, the bottom disc 7 is clamped with the bottom shell 6, and the top cover 12 is clamped with the top disc 7, and the movable door 3 is closed. Then the heating machine 5 is started, and the air outlet continuously supplies hot air, and the hot air will enter the interior of multiple rotating sleeves 10. When the driving motor 4 is working, it will drive the telescopic shaft 15 to rotate, and the telescopic shaft 15 will drive the rotating sleeve 14 to rotate. The rotating sleeve 14 can drive the multiple rotating sleeves 10 below to rotate, so that the curved surface air outlet holes 11 of the rotating sleeve 10 are arranged The hot air will periodically sweep over the vegetable slices laid out on the layer of discs 7. Since multiple discs 7 are stacked between the bottom shell 6 and the top cover 12, the hot air is always in the multi-layer space formed by the bottom shell 6, the top cover 12, and the multiple discs 7, and hot air enters each layer of space, and the hot air in the lower space will pass through the through holes 8 on the discs 7 and flow upward, and finally enter the return air pipe 13 and return to the interior of the heating machine 5. In the process of the hot air rising, the lower surface of the vegetable slices will be dried, and the hot air discharged from the air outlet 11 of this layer will dry the upper surface of the vegetable slices, saving energy and drying the vegetable slices more efficiently.

[0048] By setting the partition plate 17 and the sealing plate 18, when hot air enters the lower rotating sleeve 10, the hot air has a certain pressure when entering the rotating sleeve 10, and the air pressure will push the sealing plate 18 to move upward, so that the gas from the lower rotating sleeve 10 will enter the interior of the upper rotating sleeve 10. At the same time, the hot air from the lower rotating sleeve 10 still has a certain pressure, thereby further ensuring the amount of gas discharged from each layer of space;

[0049] The vegetable slices with different dehydration requirements or different dehydration difficulties are spread flat on the inside of the disc 7, and stacked up and down according to the dehydration difficulty, with the dehydration difficulty increasing from bottom to top, the bottom electromagnet 23 is energized to attract the permanent magnet 25, so that the permanent magnet 25 and the plug 26 move close to the electromagnet 23, so that the air outlet 11 can discharge hot air, and the other air outlets 11 are in a closed state, and the top sealing plate 18 is in a closed state. When the vegetable slices at the bottom are dehydrated and dried to a certain extent, the air outlet 11 of this layer is closed, and the air outlet 11 of the upper layer is opened. This process is repeated until the top air outlet 11 is opened, thereby drying and dehydrating the vegetable slices with different dehydration difficulties at the same time.
