Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable dehydration and drying technology, specifically to the circulating air structure of fruit and vegetable dehydration and drying equipment. Background Technology

[0002] The circulating air structure of drying equipment is a key factor affecting drying efficiency and the quality of fruits and vegetables. Currently, most fruit and vegetable dehydration and drying equipment on the market adopts a fixed main air duct, branch air duct, and return air duct design. Its air duct layout and air outlet method are relatively fixed, and it is mainly suitable for situations where the inside of the device is filled with fruits and vegetables.

[0003] In actual drying operations, due to differences in the types and quantities of fruits and vegetables to be dried, it is common for the placed fruits and vegetables to not fill the entire interior of the device. When some areas inside the device are not filled with fruits and vegetables, the air distribution duct still delivers hot air to the areas where no fruits and vegetables are placed, resulting in a large amount of hot air being wasted ineffectively. This not only increases energy consumption but also reduces the utilization efficiency of hot air. The device cannot flexibly adjust the direction of hot air delivery according to the distribution of fruits and vegetables, making it less adaptable to different loads of fruits and vegetables and unable to meet diverse drying needs.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-3 As shown, this utility model is a circulating air structure for a fruit and vegetable dehydration and drying equipment, comprising: Circulating air body 11; The flow guiding component includes an inner groove 21, a motor 22, a flow guiding plate 23, a first gear disc 24, a second gear disc 25, a tooth groove 26, and a tooth block 27. The inner groove 21 is opened on the upper and lower parts of both sides of the inner surface of the circulating air body 11. The first gear disc 24 and the second gear disc 25 are both distributed on the inner surface of the inner groove 21. The tooth block 27 is set on the outer wall of the second gear disc 25. The tooth groove 26 is opened on the outer wall of the first gear disc 24. The tooth block 27 and the tooth groove 26 are meshed and connected. One side of the flow guiding plate 23 is located on the outer surface of the second gear disc 25. The motor 22 is fixedly connected to one end of the outer surface of the circulating air body 11. The corresponding arrangement of toothed disc 24 and toothed disc 25, and the meshing connection between toothed block 27 and toothed groove 26, form a stable and reliable transmission structure. The guide plate 23 can be adjusted according to the quantity of fruits and vegetables distributed, which improves the flexibility of the equipment. By flexibly adjusting the guide plate 23, hot air can be precisely applied to the distribution area of ​​fruits and vegetables, improving the utilization rate of hot air. Whether it is a small amount of scattered fruits and vegetables or a large amount of concentrated fruits and vegetables, they can be properly dried, meeting diverse drying needs.

[0018] Drive shaft 32 is provided at both ends of the outer surface of the first gear disk 24, and drive shaft 34 is provided at both ends of the outer surface of the second gear disk 25. Through the corresponding arrangement of gear disc 24 and gear disc 25, and the meshing connection between tooth block 27 and tooth groove 26, power is transmitted to drive shaft 32 and drive shaft 34, so that the two rotate synchronously.

[0019] A support rod 31 is connected through the two drive shafts 32. One end of the support rod 31 is welded to the inner surface of the inner groove 21. A support rod 33 is connected through the two drive shafts 34. A rotating shaft 35 is provided on the inner surface of the inner groove 21. One end of the support rod 33 is rotatably connected to the outer end of the rotating shaft 35. Support rod 31 and support rod 33 support the two gear discs 24 and 25 respectively.

[0020] A support frame 36 is provided between the guide plate 23 and the drive shaft 34, and the support frame 36 is symmetrically distributed. By rotating between the first gear disk 24 and the second gear disk 25, and combined with the supporting role of the support frame 36 between the second drive shaft 34 and the guide plate 23, the guide plate 23 can be driven to adjust its angle.

[0021] Support frames 41 are fixed on both sides of the outer surface of the circulating air body 11. Ventilation slots 42 are opened on both sides of the inner surface of the circulating air body 11. A heating wire 43 is installed on one side of the inner surface of the support frame 41, and a fan 44 is installed on the other side of the inner surface. The fan 44 and heating wire 43 inside the support frame serve as hot air generating devices. After startup, the heating wire 43 is energized to generate heat, and the fan 44 operates to gather the heat and form hot air. The generated hot air is continuously transferred to the interior of the circulating air body 11 through the ventilation slot 42 between the support frame 41 and the circulating air body 11, creating a hot air flow field inside the circulating air body 11 and providing a heat source for drying fruits and vegetables.

[0022] Working principle: First, the multi-layer placement plates 51 inside the circulating air body 11 provide layered placement space for fruits and vegetables. Users can lay the fruits and vegetables to be dried flat on each layer of placement plates 51 in sequence. Then, the fan 44 and heating wire 43 inside the support frame 41 act as hot air generating devices. After starting, the heating wire 43 is energized to generate heat, and the fan 44 runs to gather the heat and form hot air. The generated hot air is continuously transferred to the interior of the circulating air body 11 through the ventilation slot 42 between the support frame 41 and the circulating air body 11. Finally, after the motor 22 starts, the power is transmitted to the drive shaft 32 and drive shaft 34 through the corresponding arrangement of the gear disc 1 24 and gear disc 25, and the meshing connection of the tooth block 27 and the tooth groove 26, so that the two rotate synchronously. Since the gear disc 1 24 and gear disc 25 can achieve forward and reverse rotation, the guide plate 23 is driven to adjust the angle. According to the number and position of the fruits and vegetables on the placement plate 51, the flow direction of the hot air in the circulating air body 11 can be changed.

[0023] This step improves the utilization rate of hot air, ensuring that both small, scattered fruits and vegetables and large, concentrated fruits and vegetables can receive appropriate drying treatment, thus meeting diverse drying needs.

[0024] Please see Figure 1 , Figure 2 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes: The pressing component includes a placement plate 51, a pressure plate 52, and pressure strips 56. The placement plate 51 is disposed on the inner surface of the circulating air body 11, the pressure plate 52 is located on the upper part of the placement plate 51, and several pressure strips 56 are fixed on the inner surface of the pressure plate 52. After the fruits and vegetables are laid flat inside the placement plate 51, the damping ring 55 moves above the damping rod 53, moving the pressure plate 52 to the lower part. This causes the pressure plate 52 to press against the surface of the fruits and vegetables, creating stable pressure. This counteracts the impact force generated by the hot air during the blowing process. This pressing action effectively prevents the fruits and vegetables from shifting or overlapping due to the force, ensuring that the fruits and vegetables remain flat. This ensures that the hot air can act evenly on each fruit and vegetable, further improving the uniformity and stability of the drying effect.

[0025] A damping rod 53 is fixed to the top of the placement plate 51, and a damping ring 55 is provided on the top of the pressure plate 52. The damping ring 55 is sleeved on the outer surface of the damping rod 53, and a limit plate 54 is fixed to the top of the damping rod 53. There is a certain damping effect between the damping ring 55 and the damping rod 53. This damping effect prevents the damping ring 55 from sliding or wobbling when it moves on the damping rod 53, thus ensuring the stability of the pressure plate 52 during movement.

[0026] Working principle: By moving the damping ring 55 outside the damping rod 53, the pressure plate 52 is lifted to the top, and fruits and vegetables can be laid flat inside the placement plate 51 in sequence. After the fruits and vegetables are laid flat inside the placement plate 51, the operator can operate the damping ring 55 to move above the damping rod 53, thereby driving the pressure plate 52 to move downward until the pressure plate 52 presses against the surface of the fruits and vegetables.

[0027] This step ensures that the fruits and vegetables remain flat, thus guaranteeing that the hot air can be applied evenly to each fruit and vegetable, further improving the uniformity and stability of the drying effect.
