Description

Technical Field

[0001] This utility model belongs to the field of lychee processing, specifically relating to a baking device for processing dried lychees. Background Technology

[0002] In the food processing industry, the production of dried lychees is an important industry. In the process of processing dried lychees, baking is one of the key steps. Its core function is to ensure that the lychees are dried evenly and retain their flavor by controlling the temperature, humidity and air circulation.

[0003] In common lychee drying equipment on the market, lychees are typically placed directly on a conveyor belt with the heating device located at the top. However, in practice, this simple placement without proper separation and organization results in uneven distribution. Some areas are densely packed with lychees, while others are sparsely distributed. This uneven distribution prevents heat from being evenly transferred to each lychee during the heating process. With the heating device only at the top, the lychees are heated from above, resulting in insufficient heating at the bottom. This uneven heating not only leads to inconsistent drying speeds and reduced production efficiency but also causes some lychees to fail to achieve the desired drying effect due to insufficient heating, thus affecting the quality of the dried lychees. Utility Model Content

[0004] To overcome the problem of uneven distribution of lychees during the use of lychee drying equipment, which leads to poor drying effect and affects the quality of dried lychees, a new type of lychee drying equipment is proposed.

[0005] The technical solution of this utility model is as follows: a baking device for processing dried lychees, including a conveying mechanism, the conveying mechanism including a fixed box, a conveying frame fixedly connected to the inner walls of the front and rear ends of the fixed box, a metal mesh belt installed on the inner walls of the front and rear ends of the conveying frame, a feeding mechanism installed at the upper end of the fixed box, the feeding mechanism including a storage box, partitions with equal front and rear distances fixedly connected to the inner walls of the left and right ends of the storage box, baffles rotatably installed on the inner walls of the front and rear ends of the storage box, the baffles being located at the lower end of the partitions, a servo motor II fixedly connected to the outer wall of the storage box, the output end of the servo motor II being connected to the rotating shaft of the baffle, a feeding pipe fixedly connected to the lower opening of the storage box, the lower opening of the feeding pipe corresponding to the upper outer wall of the metal mesh belt, a baking mechanism installed at the left end of the fixed box, the baking mechanism including a heat insulation box, a baking cover fixedly connected to the inner wall of the heat insulation box, the baking cover surrounding the outer wall of the metal mesh belt, and a spirally wound heating tube fixedly connected to the inner wall of the baking cover.

[0006] Furthermore, symmetrical conveyor rollers are rotatably installed on the inner edges of the front and rear ends of the conveyor frame. A metal mesh belt is installed on the outer wall of the conveyor rollers. A servo motor is fixed to the outer wall of the conveyor frame, and the output end of the servo motor is connected to the rotating shaft of the left conveyor roller.

[0007] Furthermore, a protective cover is fixed to the outer wall of the servo motor, and a cooling fan is installed in the front opening of the protective cover, with the air inlet of the cooling fan corresponding to the servo motor.

[0008] Furthermore, the storage box is fixed inside the upper opening of the fixed box, the heat insulation box is fixed to the left end of the fixed box, and a dehumidifier is installed on the upper end of the heat insulation box.

[0009] Furthermore, a recycling mechanism is installed at the left end of the baking mechanism, which includes a recycling box fixed to the left end of the insulated box.

[0010] Furthermore, air grating one and air grating two are fixedly connected to the inner walls of the upper and lower ends of the recycling bin, respectively. A hot air blower is fixedly connected to the upper end of the recycling bin. The air outlet of the hot air blower is connected to the air grating one pipe. The air outlet of air grating one corresponds to the upper end of the metal mesh belt.

[0011] Furthermore, a suction fan is fixedly connected to the front end of the recycling bin. The air inlet of the suction fan is connected to the second air grid pipe. A third air grid is fixedly connected to the upper inner wall of the fixed box. The third air grid is connected to the air outlet pipe of the suction fan. The air outlet of the third air grid corresponds to the upper end of the metal mesh belt.

[0012] The beneficial effects of this utility model are as follows: the storage box can support the lychees, the partition can evenly separate the lychees, the baffle can block the lower end of the partition to prevent the lychees from slipping, the output end of the servo motor can drive the baffle to rotate, and the baffle can be periodically unfolded so that the lychees enter the feeding pipe along the partition in sequence, and the lychees are evenly guided to the upper end of the metal mesh belt. Then, the baking hood can surround the outer wall of the metal mesh belt, and the spirally distributed heating tubes can evenly heat the upper and lower ends of the lychees. Compared with the existing lychee drying and baking device, the added feeding mechanism can evenly and orderly transport the lychees to the upper end of the metal mesh belt, keeping the lychees at a suitable distance. The added baking mechanism can synchronously heat the upper and lower ends of the lychees, improve the uniformity of baking, and thus reduce the problem of uneven heating of lychees.

[0022] The storage box 201 can hold the lychees, the partition 202 can evenly separate the lychees, and the baffle 203 can block the lower end of the partition 202 to prevent the lychees from slipping. The output end of the servo motor 204 can drive the baffle 203 to rotate, and the baffle 203 can be periodically unfolded so that the lychees enter the feeding pipe 205 along the partition 202 in sequence. The lychees are evenly guided to the upper end of the metal mesh belt 104, and then the baking cover 302 can surround the outer wall of the metal mesh belt 104. The spirally distributed heating tubes 303 can evenly heat the upper and lower ends of the lychees, improving the quality of lychee baking.

[0023] Please see Figure 3 In this embodiment, symmetrical conveying rollers 103 are rotatably installed on the inner edges of the front and rear ends of the conveying frame 102. A metal mesh belt 104 is installed on the outer wall of the conveying rollers 103. A servo motor 105 is fixedly connected to the outer wall of the conveying frame 102. The output end of the servo motor 105 is connected to the rotating shaft of the left conveying roller 103. In use, the output end of the servo motor 105 can drive the conveying roller 103 to rotate, thereby driving the metal mesh belt 104 to rotate, conveying the lychees in the fixed box 101 to the baking mechanism 3, and sending out the baked lychees. A protective cover 106 is fixedly connected to the outer wall of the servo motor 105. A cooling fan 107 is installed in the front opening of the protective cover 106. The air inlet of the cooling fan 107 corresponds to the servo motor 105. In use, the protective cover 106 can protect the servo motor 105, and the cooling fan 107 can dissipate heat from the servo motor 105, preventing the baking mechanism 3 from affecting the operation of the servo motor 105.

[0024] Please see Figures 4-5 In this embodiment, the storage box 201 is fixedly connected to the upper opening of the fixed box 101, and the heat insulation box 301 is fixedly connected to the left end of the fixed box 101.

During use, the heat insulation box 301 can support the recycling mechanism 4 and reduce the heat loss inside the heat insulation box 301.

[0025] Please see Figure 6In this embodiment, air grating 1 403 and air grating 2 404 are fixedly connected to the inner walls of the upper and lower ends of the recycling box 401, respectively. A hot air blower 402 is fixedly connected to the upper end of the recycling box 401. The air outlet of the hot air blower 402 is connected to the air grating 1 403 via a pipe. The air outlet of the air grating 1 403 corresponds to the upper end of the metal mesh belt 104. In use, the hot air blown out by the hot air blower 402 can supply the air grating 1 403 to further heat the lychees leaving the baking mechanism 3, and drive the hot airflow into the air grating 2 404. The front end of the recycling box 401 A suction fan 405 is fixedly connected, and the air inlet of the suction fan 405 is connected to the pipe of the second air grid 404. A third air grid 406 is fixedly connected to the upper inner wall of the fixed box 101, and the third air grid 406 is connected to the air outlet of the suction fan 405. The air outlet of the third air grid 406 corresponds to the upper end of the metal mesh belt 104. In use, the suction fan 405 can drive the airflow into the second air grid 404 and guide the hot air in the recovery box 401 to the third air grid 406 to preheat the lychees before they enter the baking mechanism 3, thereby improving energy utilization.

[0026] During operation, firstly, servo motor 105 drives the metal mesh belt 104 to rotate, and cooling fan 107 is activated to dissipate heat from servo motor 105. Then, heating tube 303 is activated to heat the baking hood 302 to a suitable temperature. Next, the lychees to be baked are placed in storage box 201, and hot air blower 402 is activated to supply hot air to air vent 403. Simultaneously, suction fan 405 is activated to absorb the heat emitted by hot air blower 402 and baking mechanism 3 and supply it to air vent 406. Then, dehumidifier 304 is activated, and the output of servo motor 204 drives baffle 203 to rotate periodically, causing the lychees to intermittently roll onto the upper end of metal mesh belt 104. Finally, after the metal mesh belt 104 carries the lychees through baking mechanism 3 and they are baked, they are sent out of recycling box 401.

[0027] Through the above steps, the storage box 201 can carry the lychees, the partition 202 can evenly separate the lychees, the baffle 203 can block the lower end of the partition 202 to prevent the lychees from slipping, the output end of the servo motor 204 can drive the baffle 203 to rotate, and the baffle 203 can be periodically unfolded so that the lychees enter the feeding pipe 205 along the partition 202 in sequence, and the lychees are evenly guided to the upper end of the metal mesh belt 104. The baking cover 302 can surround the outer wall of the metal mesh belt 104, and the spirally distributed heating tubes 303 can evenly heat the upper and lower ends of the lychees. This solves the problem that the uneven distribution of lychees during the use of the lychee drying device leads to poor baking effect and affects the quality of the dried lychees.
