Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of camellia fruit processing equipment, and in particular to a layered rack for air-drying fresh camellia fruit. Background Technology
[0002] Freshly harvested camellia oleifera fruits have a high moisture content, making them highly susceptible to mold and spoilage, and difficult to store. Therefore, fresh camellia oleifera fruits need to be dried after harvesting. Drying the seeds to a moisture content of less than 13% in a timely manner can effectively prevent mold growth, extend storage time, and facilitate subsequent oil extraction or other uses.
[0003] Traditional methods for drying fresh camellia fruit include sun drying and air drying. These methods have many drawbacks, such as long drying time, susceptibility to weather conditions, unstable drying quality, low drying efficiency, and inconvenience for large-scale processing of fresh camellia fruit. Furthermore, they cannot meet the different drying requirements of different sizes of fresh camellia fruit, which may result in low quality of air-dried fresh camellia fruit. Utility Model Content
[0004] This utility model discloses a layered rack for air-drying fresh camellia fruit, aiming to solve the technical problem that traditional methods of drying fresh camellia fruit, such as sun drying and natural air drying, have many shortcomings, such as long drying time, susceptibility to weather, unstable drying quality, low drying efficiency, inconvenience for large-scale processing of fresh camellia fruit, and inability to meet different drying needs according to different sizes of fresh camellia fruit, which may lead to low air-dried quality of fresh camellia fruit.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A tiered rack for air-drying fresh camellia fruit includes a drying box with four sets of access doors. The drying box has two mounting racks and partitions inside, and also includes:
[0007] Drying mechanism: Located on both outer walls of the mounting frame, the drying mechanism includes four mounting boxes. One outer wall of each mounting box is provided with a wind box. The wind box has two air inlet chambers and one air outlet chamber near the two ends and the middle, respectively. A fan is installed inside the air outlet chamber, and a filter element is installed inside the air inlet chamber. Buffer chambers are provided inside the mounting boxes and on one side of the air inlet and air outlet chambers. Six equally spaced ventilation holes are provided at the connection between the buffer chambers and the air outlet and air inlet chambers, respectively. Mounting openings are provided on both outer walls of the mounting frame. A limiting frame is provided on the inner wall of the mounting opening, and an ultraviolet light lamp is provided inside the limiting frame.
[0008] Adjustment mechanism: located on both sides of the air-drying mechanism.
[0009] The above technical solution improves the drying efficiency of fresh camellia fruit, ensures drying quality according to production needs, reduces floor space, and lowers labor intensity. Specifically, during use, multiple fresh camellia fruits are first fixed to the mounting frame using an adjustment mechanism, and then the inspection door is closed. This creates a closed drying environment for the fruit in the drying chamber. The partitions further divide the internal space of the drying chamber, helping to optimize airflow and ensure that every corner of the fruit is thoroughly dried. The air inlet chamber introduces external air, which is then purified by a filter. The exhaust chamber uses a fan to accelerate air circulation and dehumidify the air. The system effectively prevents fresh camellia fruit from molding and spoiling. The ultraviolet spotlights not only provide illumination but, more importantly, have a sterilizing effect. During the drying process, the ultraviolet light kills microorganisms and bacteria on the surface of the fresh camellia fruit, improving the hygiene and safety of the product. The humidity sensor enhances the automatic adjustment of ventilation and dehumidification. The humidity inside the drying chamber can be flexibly controlled by the humidity sensor. When the drying process needs to be accelerated, the fan speed can be controlled to allow air inside the drying chamber to enter the exhaust chamber and be discharged. With the help of the air inlet chamber, filter, and buffer chamber, the input of dry air is achieved.
[0010] In a preferred embodiment, the top outer wall of the mounting bracket is provided with two humidity sensors, which are electrically connected to the fan.
[0011] In this solution, the humidity sensor can accurately measure and report the humidity information of the space above the mounting frame, and monitor and adjust the working status of the drying mechanism in real time to ensure that the fresh camellia fruit is dried under the best humidity conditions. For example, when the humidity sensor detects that the humidity inside the drying box is too high, the fan speed is controlled to speed up the dehumidification. Conversely, when the humidity is too low, the fan speed can be reduced to avoid the fresh camellia fruit from drying out too much.
[0012] In a preferred embodiment, the adjustment mechanism includes four drying trays, and the outer walls of the mounting frame are provided with two rows of equally spaced limiting holes. The outer walls of the drying trays are provided with two limiting posts, and the limiting posts are connected to the limiting holes by threads.
[0013] In this design, the layout is flexible enough to accommodate different sizes of fresh camellia fruit, drying trays, and different drying needs. By adjusting the spacing between the limiting columns, the spacing between adjacent drying trays can be adjusted to ensure that each layer receives sufficient air circulation and drying effect.
[0014] As can be seen from the above, a layered rack for air-drying fresh camellia fruit includes a drying box, which includes four sets of inspection doors. The interior of the drying box is equipped with two mounting racks and partitions, and also includes:
[0015] Drying mechanism: Located on both outer walls of the mounting frame, the drying mechanism includes four mounting boxes. One outer wall of each mounting box is provided with a wind box. The wind box has two air inlet chambers and one air outlet chamber near the two ends and the middle, respectively. A fan is installed inside the air outlet chamber, and a filter element is installed inside the air inlet chamber. Buffer chambers are provided inside the mounting boxes and on one side of the air inlet and air outlet chambers. Six equally spaced ventilation holes are provided at the connection between the buffer chambers and the air outlet and air inlet chambers, respectively. Mounting openings are provided on both outer walls of the mounting frame. A limiting frame is provided on the inner wall of the mounting opening, and an ultraviolet light lamp is provided inside the limiting frame.
[0016] Adjustment mechanism: Located on both sides of the air-drying mechanism. The layered rack for air-drying fresh camellia fruit provided by this utility model has the technical effects of improving the drying efficiency of fresh camellia fruit, ensuring drying quality according to production needs, reducing floor space, and reducing labor intensity.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0023] The layered rack for air-drying fresh camellia fruit disclosed in this utility model is mainly applicable to the traditional drying methods for fresh camellia fruit, such as sun drying and natural air drying. These commonly used methods have many shortcomings, such as long drying time, susceptibility to weather conditions, unstable drying quality, low drying efficiency, and inconvenience for large-scale processing of fresh camellia fruit. At the same time, they cannot meet the different drying needs of fresh camellia fruit of different sizes, which may lead to low drying quality of fresh camellia fruit.
[0024] Reference Figure 1 , Figure 3 and Figure 4 A layered rack for air-drying fresh camellia fruit includes an air-drying box 1, which includes four sets of inspection doors 2. The interior of the air-drying box 1 is equipped with two mounting racks 4 and partitions 3. It also includes:
[0025] Drying mechanism: Located on both outer walls of the mounting frame 4, the drying mechanism includes four mounting boxes 18. One outer wall of the mounting box 18 is provided with a wind box 5. The wind box 5 has two air inlet chambers and one air outlet chamber 12 near the two ends and the middle, respectively. A fan 13 is installed inside the air outlet chamber 12, and a filter element 11 is installed inside the air inlet chamber. Buffer chambers 16 are provided inside the mounting box 18 and on one side of the air inlet chamber and the air outlet chamber 12. Six equally spaced ventilation holes 17 are provided at the connection between the buffer chamber 16 and the air outlet chamber 12. The two outer walls of the mounting frame 4 are provided with mounting openings 8. The inner wall of the mounting opening 8 is provided with a limiting frame 14. An ultraviolet light lamp 15 is provided inside the limiting frame 14.
[0026] Adjustment mechanism: located on both sides of the drying mechanism.
[0027] The inspection door 2 is located between the inner wall of one side of the drying box 1 and the partition 3, and the inspection door 2 is attached to one side of the air box 5. This arrangement facilitates the handling of fresh camellia fruit, does not hinder the normal operation of the drying mechanism, prevents air leakage, and improves drying efficiency.
[0028] In actual use, the mounting box 18 is installed on one outer wall of the mounting port 8, and the mounting box 18 is the same size as the mounting port 8.
[0029] The top outer wall of the mounting frame 4 is equipped with two humidity sensors 10. The humidity sensors 10 are electrically connected to the fan 13. The humidity sensors 10 can accurately measure and report the humidity information of the space above the mounting frame 4, and monitor and adjust the working status of the drying mechanism in real time to ensure that the fresh camellia fruit is dried under the best humidity conditions. For example, when the humidity sensor 10 detects that the humidity inside the drying box 1 is too high, the speed of the fan 13 is controlled to speed up the dehumidification. Conversely, when the humidity is too low, the speed of the fan 13 can be reduced to avoid the fresh camellia fruit from drying out too much.
[0030] In the specific implementation process, the mounting frame 4 has an inverted "U" shaped structure. A connecting rod is provided between two adjacent mounting frames 4. One end of the connecting rod passes through the outer wall of one side of the partition 3. The mounting frame 4 adopts an inverted "U" shaped structure design. This design not only makes the mounting frame 4 more stable, but also makes full use of the space inside the drying box 1 to increase the loading capacity of fresh camellia fruit. The connecting rod firmly connects two adjacent mounting frames 4 together. This design not only enhances the structural stability of the entire mounting frame 4, but also makes the mounting frame 4 less prone to shaking or deformation during the drying process.
[0031] Specifically, in use, multiple fresh camellia fruits are fixed to the mounting frame 4 using the adjustment mechanism, and then the inspection door 2 is closed, thus providing a closed drying environment for the fresh camellia fruits in the drying chamber 1. The partition 3 further divides the internal space of the drying chamber 1, helping to optimize the airflow path and ensure that the fresh camellia fruits in every corner are fully dried. The air inlet chamber is used to introduce external air, which is purified by the filter element 11. The exhaust chamber 12 accelerates air circulation and dehumidification through the fan 13, thereby effectively preventing the fresh camellia fruits from becoming moldy and spoiled. The ultraviolet spotlight 15 not only provides a certain lighting effect, but more importantly, it has a sterilization effect. During the drying process, the ultraviolet light can kill bacteria. The removal of microorganisms and bacteria on the surface of fresh camellia fruit improves the hygiene and safety of the product. The humidity sensor 10 enhances the automatic adjustment of ventilation and dehumidification. The humidity sensor 10 flexibly regulates the humidity inside the drying chamber 1. When it is necessary to accelerate the drying process, the fan 13 speed can be controlled, allowing air inside the drying chamber 1 to enter the exhaust chamber 12 and be discharged. Under the action of the air inlet chamber, filter element 11, and buffer chamber 16, dry air is input, which is beneficial to the air exchange inside the drying chamber 1 and improves the ventilation and dehumidification effect of the device. This device can improve the drying efficiency of fresh camellia fruit, and can ensure drying quality, reduce floor space, and reduce labor intensity according to production needs.
[0032] Reference Figure 1 and Figure 2 In a preferred embodiment, the adjustment mechanism includes four drying trays 9, and two rows of equally spaced limiting holes 6 are provided on the outer walls of both sides of the mounting frame 4. Two limiting posts 7 are provided on the outer walls of both sides of the drying trays 9, and the limiting posts 7 are connected to the limiting holes 6 by threads.
[0033] Specifically, this design allows for flexible adaptation to different sizes of fresh camellia fruit, drying trays 9, and different drying needs. By adjusting the spacing between the limiting columns 7, the layer spacing between two adjacent drying trays 9 can be adjusted to ensure that each layer can get sufficient air circulation and drying effect.
[0034] Reference Figure 1 and Figure 2 In a preferred embodiment, the bottom outer wall of the drying tray 9 is provided with several ventilation holes, which greatly improves the drying efficiency. By allowing airflow through the drying tray 9, the bottom and sides of the fresh camellia fruit can be fully dried, thereby shortening the drying time and avoiding quality problems caused by uneven drying of the fresh camellia fruit.
[0035] Working principle: During use, multiple fresh camellia fruits are fixed on the mounting frame 4 using the adjustment mechanism, and then the inspection door 2 is closed, thus providing a closed drying environment for the fresh camellia fruits in the drying box 1. The partition 3 further divides the internal space of the drying box 1, helping to optimize the airflow path and ensure that the fresh camellia fruits in every corner are fully dried. The air inlet chamber is used to introduce external air, which is purified by the filter element 11. The exhaust chamber 12 accelerates air circulation and dehumidification through the fan 13, thereby effectively preventing the fresh camellia fruits from molding and deteriorating. The ultraviolet spotlight 15 not only... It can provide a certain lighting effect, and more importantly, it has a sterilization effect. During the drying process, ultraviolet light can kill microorganisms and bacteria on the surface of fresh camellia fruit, improving the hygiene quality and safety of the product. The humidity sensor 10 can enhance the automatic adjustment of ventilation and dehumidification. The humidity inside the drying box 1 can be flexibly controlled by the humidity sensor 10. When it is necessary to accelerate the drying process, the speed of the fan 13 can be controlled so that the air inside the drying box 1 enters the air exhaust chamber 12 and is discharged. Under the action of the air inlet chamber, filter element 11 and buffer chamber 16, the input of dry air is realized.
[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
