[0022] Dehydrated vegetables are a common form of vegetable storage in current convenience foods. By removing the moisture from the vegetables to retain the color and nutrients of the vegetables, they are used in the processing of some packaged foods. The dehydration process generally includes hot air drying and vacuum freeze drying. One method is to use hot air to evaporate the moisture on the surface or inside of the vegetables, and the other is to remove the moisture from the vegetables by rapid freezing. However, the aforementioned hot air drying method requires a high processing temperature and a long processing time, resulting in energy waste. Therefore, the utility model proposes a dehydrated vegetable drying device to improve the energy utilization and thermal efficiency of existing drying equipment.

[0023] like Figures 1 to 4 As shown, the utility model provides a dehydrated vegetable drying device.

[0024] The specific dehydrated vegetable drying equipment includes a box body 13, an upper drying chamber 1 and a lower drying chamber 2 arranged in layers, the upper drying chamber 1 and the lower drying chamber 2 are opened at both ends and are arranged in parallel with each other in the box body 13, a plurality of air pipes 3 are provided between the upper drying chamber 1 and the lower drying chamber 2, a first conveyor belt 11 is provided in the upper drying chamber 1, and a second conveyor belt 12 is provided in the lower drying chamber 2, and the two ends of the air pipe 3 are respectively aligned with the bottom of the first conveyor belt 11 and the top of the second conveyor belt 12, and the first conveyor belt 11 and the second conveyor belt 12 are used to on the conveying tray 10; a feeding mechanism 4 is provided at both ends of the upper drying chamber 1 and the lower drying chamber 2, and the feeding mechanism 4 includes a material box 6 with multiple material bins, a material box lifting platform 5, a loading mechanism 7 and a unloading mechanism 8, the loading mechanism 7 is configured to insert the tray 10 into the material box 6, and the unloading mechanism 8 is configured to push the tray 10 in the material box 6 out of the material box 6 and convey it to the unloading mechanism, the material box 6 is arranged on the material box lifting platform 5, and the material box lifting platform 5 is arranged at both ends of the first conveyor belt 11 or the second conveyor belt 12.

[0025] like Figure 1 and Figure 2 As shown, the upper drying chamber 1 and the lower drying chamber 2, arranged on the upper and lower layers of the housing 13, are connected by an air pipe 3. This allows excess heat from heating the articles to be dried on the second conveyor belt 12 in the lower drying chamber 2 to pass through the air pipe 3 into the upper drying chamber 1, heating the articles to be dried on the first conveyor belt 11. This allows the heating components in the upper drying chamber 1 to heat the articles to be dried at a lower heating power, saving energy and improving the energy efficiency of the drying equipment. At the same time, the insulation effect of the entire housing 13 reduces heat loss, speeds up the drying time, and thus improves the heat treatment efficiency of the articles to be dried.

[0026] like Figure 1 As shown by the arrows, the flow process of the dried materials in the upper and lower drying chambers is indicated:

[0027] First, the material to be dried is placed on a tray 10 and enters the second conveyor 12 from the left side of the second conveyor 12 in the lower drying chamber 2. It is then dragged to the right by the second conveyor 12. During this process, the heating assembly in the lower drying chamber 2 continues to heat the material to be dried. After drying at the lower level, the loading mechanism 7 inserts the trays 10 one by one into the material box 6. When the material box 6 is full, the material box lifting platform 5 lifts one end of the first conveyor 11 in the upper drying chamber 1. The loading mechanism 7 then pushes the tray 10 out of the material box 6 and docks it with the first conveyor 11. At this time, the upper and lower surfaces of the material to be dried are heated simultaneously. When the tray 10 reaches the left side of the first conveyor 11, drying is completed. The unloading mechanism 8 then transfers the fully dried material (all materials referred to below refer to diced vegetables, such as diced tomatoes and carrots) to the unloading mechanism. Because the material to be dried in the upper drying chamber 1 is dried from both sides, the material to be dried can be evenly dried. In other words, the present invention also solves the problem of uneven drying of the material to be dried on both sides.

[0028] It should be noted that the aforementioned loading mechanism 7 and unloading mechanism 8 can utilize motors to drive belts on rollers, utilizing friction between the tray 10 and the belt surface to deliver the tray 10 into or out of the material box 6. Furthermore, the aforementioned first conveyor belt 11 and second conveyor belt 12 can utilize heat-resistant belts or chain conveyor belts, which are not specifically limited in this embodiment. Furthermore, to increase the flow of hot air in the air delivery pipe 3, a fan can be installed in the upper drying chamber 1 to accelerate the flow of hot air, and this design is also within the scope of protection of this application.

[0029] In addition, it should be noted that the aforementioned heating component for heating the object to be dried can be an infrared lamp heating component, because the infrared lamp has a wide radiation range, high heating power, and high light-to-heat conversion efficiency.

[0030] In some embodiments, the drying equipment may also include a hoisting mechanism 9 parallel to the first conveyor belt 11 or the second conveyor belt 12, and the hoisting mechanism 9 includes a reel 91 and a lever 92 detachably connected to the reel 91; the lever 92 is provided with a rolling portion at one end for contacting the object to be dried.

[0031] like Figure 3As shown, in this embodiment, to increase the uniformity of the dried material within the tray 10, a hoisting mechanism 9 is disposed above the first conveyor belt 11 and / or the second conveyor belt 12. This hoisting mechanism 9 is used to evenly distribute the material within the tray 10. The rotation of a reel 91 within the hoisting mechanism 9 drives a lever 92 on the reel 91. The rotating lever 92 flattens the dried material, preventing uneven drying. Furthermore, the raised portion at the end of the lever 92 is a comb-like structure, tilted at a predetermined angle. This allows the comb-like structure to scoop the dried material from the bottom of the tray 10 when it contacts it. During rotation, the dried material is flipped over, resulting in multiple flips during the drying process, further enhancing the uniformity of the dried material.

[0032] In addition, in some embodiments, a plurality of levers 92 may be provided on the aforementioned reel 91, and the plurality of levers 92 may be arranged in a curve on the reel 91, and the rolling portions of the plurality of levers 92 may have the same inclination direction. When the levers 92 are distributed in a curve on the reel 91, the area of the material to be dried stirred by the levers 92 may be increased, thereby improving the efficiency of the stirring.

[0033] In some embodiments, the bottom of the tray 10 is a mesh structure, and the air holes on the mesh structure are evenly distributed and smaller than the minimum size of the objects to be dried.

[0034] In this embodiment, the tray 10 must not only support the dried material but also be permeable to allow excess heat within the lower drying chamber 2 to pass through the tray 10 and reach the lower and upper surfaces of the dried material. Therefore, the mesh belt structure must have uniformly spaced air holes to prevent the dried material particles from falling out. The mesh belt structure can be made of woven steel mesh or perforated stainless steel, and this embodiment does not impose specific limitations on this.

[0035] In some embodiments, limiting grooves 100 are provided on both sides of the aforementioned first conveyor belt 11 and the second conveyor belt 12, and a vibration component is provided under the first conveyor belt 11 in the upper drying chamber 1, and the vibration component is in contact with the tray 10, and the edge of the tray 10 is engaged with the limiting groove 100.

[0036] like Figure 4 As shown, in this embodiment, on the one hand, to increase the mobility of the objects to be dried on the conveyor belt, a vibration assembly is provided below the first conveyor belt 11 and the second conveyor belt 12, causing the conveyor belt to vibrate at a preset low frequency. This vibration effect acts on the tray 10. To prevent the tray 10 from detaching from the conveyor belt, limiting grooves 100 are provided on both sides of the first conveyor belt 11 and the second conveyor belt 12, so that the edges of the tray 10 are stuck in the limiting grooves 100 to achieve the purpose of limiting. The vibration assembly can be driven by a cylinder or a motor, and this embodiment does not impose specific restrictions on this.

[0037] In some embodiments, the aforementioned unloading mechanism includes a flipping mechanism and a circulation mechanism, the flipping mechanism includes a pallet 10 positioning clamp and a push rod, the push rod rotates relative to the pallet 10 positioning clamp; the pallet 10 positioning clamp is arranged on the conveyor belt of the circulation mechanism and docked with the conveyor belt.

[0038] In this embodiment, the dried material is still in the tray 10, and it is necessary to pour it out of the tray 10 and let the tray 10 take on new materials that need to be dried and continue to use them in a cycle. Figure 1 A turning mechanism is provided at the left end of the discharge mechanism on the left side of the center to discharge the dried material, and a circulation mechanism is provided to allow the empty tray 10 to continue to circulate after the material has been discharged. The specific turning mechanism can be provided with a tray 10 positioning clamp to fix the tray 10, and then a push rod can push the tray 10 positioning clamp to an inclined position to complete the pouring action, or other similar structures can be used to complete the pouring action, and this embodiment does not impose specific limitations on this.

[0039] In some embodiments, a controller may be further provided on the box body 13, and a liquid accumulation tank 14 (e.g., Figure 1 The controller is connected to the power equipment in the upper drying chamber 1, the lower drying chamber 2, and the power equipment in the clinker mechanism. The liquid sump 14 is tilted. The controller is intended to control the movement of the tray 10, the entry and exit of the tray 10 in the material box 6, and intelligently control the heating temperature of the upper drying chamber and the lower drying chamber 2 in the housing 13, thereby achieving automated production.

[0040] Finally, the utility model provides a dehydrated vegetable drying device, including a box body 13, an upper drying chamber 1 and a lower drying chamber 2 arranged in layers, the upper drying chamber 1 and the lower drying chamber 2 are opened at both ends and are arranged in parallel with each other in the box body 13, a plurality of air pipes 3 are arranged between the upper drying chamber 1 and the lower drying chamber 2, a first conveyor belt 11 is arranged in the upper drying chamber 1, and a second conveyor belt 12 is arranged in the lower drying chamber 2, the two ends of the air pipe 3 are respectively aligned with the bottom of the first conveyor belt 11 and the top of the second conveyor belt 12, and the first conveyor belt 11 is provided with a plurality of air pipes 3. The second conveyor belt 12 is used to convey the pallets 10; a feeding mechanism 4 is provided at both ends of the upper drying chamber 1 and the lower drying chamber 2. The feeding mechanism 4 includes a material box 6 with multiple material silos, a material box lifting platform 5, a loading mechanism 7, and a unloading mechanism 8. The loading mechanism 7 is configured to insert the pallets 10 into the material box 6, and the unloading mechanism 8 is configured to push the pallets 10 in the material box 6 out of the material box 6 and convey them to the unloading mechanism. The material box 6 is provided on the material box lifting platform 5, and the material box lifting platform 5 is provided at both ends of the first conveyor belt 11 or the second conveyor belt 12. The utility model improves the energy utilization rate of the drying equipment, increases the thermal efficiency of the drying process, and realizes automated drying of materials.
