Description

Technical Field

[0001] This invention relates to the field of agricultural pollen processing machinery technology, specifically to a circulating anther drying box and drying method based on temperature and humidity feedback-controlled airflow. Background Technology

[0002] In fruit tree cultivation and hybridization breeding, artificial pollination is an important measure to improve fruit set rate and fruit quality. After anther collection, it needs to be dried to induce anther dehiscence and release pollen. Pollen activity is closely related to drying temperature. For temperature-sensitive fruit tree pollen such as kiwifruit, the drying temperature must be strictly controlled between 21 and 28°C. Once the temperature exceeds 28°C, pollen activity will be rapidly lost, while too low a temperature will prolong the drying time. Therefore, precise low-temperature constant temperature control is the core technical requirement for anther drying.

[0003] Existing anther drying equipment mostly adopts a static shelf structure, such as the scheme disclosed in Chinese patent document application number 201520435179.3, where anther trays are placed on fixed shelves for static drying. Due to the natural upward movement of hot air, vertical and horizontal temperature differences easily form inside the chamber, leading to overheating of the upper anthers and insufficient drying of the lower layers. This results in inconsistent drying levels across anther trays, and some pollen loses activity or even becomes inactive due to overheating. Regarding temperature control, existing equipment typically uses only a single temperature sensor to control heating via an on / off switch and maintain a constant hot air volume. Data collected from a single point is insufficient to accurately reflect the overall temperature field, making it difficult to precisely control the temperature inside the chamber below 28°C. Furthermore, under a constant air volume, pollen already released in the anther trays that have already produced pollen is easily blown away by the large airflow, causing pollen loss and waste.

[0004] To address the issue of uneven heating during static drying, some improved solutions have been developed. For example, Chinese utility model patent CN208765387U uses a "slider + guide rod + flexible rope" to achieve the lifting and lowering of a multi-layered drying platform. However, once the platform is in position, it remains stationary, essentially still a static layered drying process. This fails to fundamentally eliminate the impact of uneven temperature distribution and also fails to solve the problems of precise temperature control and adaptive airflow adjustment during the powder bursting period. Furthermore, static drying has low heat exchange efficiency, making it difficult to meet the needs of large-scale production.

[0005] In summary, the existing technology has at least the following technical problems that need to be solved: 1) Static shelf drying leads to uneven temperature distribution inside the chamber, and inconsistent heating of each anther tray; 2) With a single temperature sensor and switch-type control, it is difficult to accurately control the temperature inside the chamber below 28℃; 3) The air volume is constant throughout the drying process, and pollen is blown away after bursting, resulting in loss and waste; 4) Existing lifting improvement schemes are still essentially static drying and fail to achieve continuous dynamic movement throughout the drying process; 5) Static drying has low heat exchange efficiency, which is difficult to meet the needs of large-scale pollen production.

[0006] Therefore, there is an urgent need for a fruit tree anther drying box and drying method that can simultaneously achieve dynamic and uniform heating of the anther tray, precise low-temperature constant temperature control, and adaptive airflow adjustment. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a circulating anther drying box and drying method based on temperature and humidity feedback-controlled airflow.

[0008] This invention discloses a circulating anther drying box based on temperature and humidity feedback air control, including a drying box body. The drying box body is divided into a heating chamber, a drying chamber and an exhaust chamber by a partition. A first ventilation section is provided at the lower part of the partition between the heating chamber and the drying chamber, and a second ventilation section is provided at the upper part of the partition between the drying chamber and the exhaust chamber, forming an air duct structure in which hot air enters from the bottom and moisture is exhausted from the top. The drying chamber is equipped with a circulating motion mechanism and multiple temperature detection units. The circulating motion mechanism includes a drive device, a transmission component, and a flower anther tray support component. The drive device drives the flower anther tray support component to perform up-and-down circulating motion through the transmission component. The flower anther tray support component is suspended by a rotatable connector, so that the supported flower anther tray remains horizontal under the action of gravity during the circulating motion. The multiple temperature detection units are used to collect temperature data at multiple points in the drying chamber. The heating chamber is equipped with a heating device to generate the heat required for drying in the drying chamber; The exhaust chamber is equipped with an exhaust device and a humidity detection unit. The exhaust device is used to exhaust the moisture in the drying chamber, and the humidity detection unit is used to detect the humidity of the exhaust. The heating device, exhaust device, multiple temperature detection units, and humidity detection unit are electrically connected to the control module. The control module is used to adjust the power of the heating device according to the temperature signals from the multiple temperature detection units and to adjust the exhaust volume of the exhaust device according to the humidity signals from the humidity detection units.

[0009] As a further improvement of the present invention, the cyclic motion mechanism further includes a stabilizing bracket, which includes a base and four support columns vertically fixed on the base, the four support columns being distributed in a matrix; the driving device, transmission component and anther tray bearing component are all mounted on the stabilizing bracket.

[0010] As a further improvement of the present invention, the transmission assembly includes sprockets, a transmission chain, and a transmission shaft; the four sprockets are symmetrically arranged in pairs on two opposing rows of support columns of the stabilizing bracket; two sprockets on the same side are spaced apart vertically and are synchronously connected by the transmission chain; two sprockets located at the upper or lower part are synchronously connected by the transmission shaft, and at least one sprocket is connected to the drive device.

[0011] As a further improvement of the present invention, the anther tray support assembly includes multiple sets of anther tray support portions, which are distributed at intervals along the transmission chain. Each set of anther tray support units includes at least one anther tray support, a rotating connector, a connecting shaft, and a semi-circular connector. The anther tray support is used to support the anther tray. Each end of the anther tray support is provided with a rotating connector. Each end of the connecting shaft passes through the corresponding rotating connector. The rotating connector can rotate around the connecting shaft. Each end of the connecting shaft is fixedly connected to the corresponding semi-circular connector. The semi-circular connector is fixedly connected to the transmission chain.

[0012] As a further improvement of the present invention, when the anther tray support in the anther tray bearing part is multi-layered, the two ends of the adjacent two layers of anther tray supports are respectively fixedly connected at intervals by connecting brackets.

[0013] As a further improvement of the present invention, multiple sets of temperature detection units are respectively arranged in the upper, middle and lower parts of the drying chamber.

[0014] As a further improvement of the present invention, the bottom of the drying chamber is provided with casters with brakes; the drying chamber also includes a door, the door is provided with a transparent observation window and a temperature and humidity control box, the temperature and humidity control box is electrically connected to the control module, and is used to set drying parameters and display the temperature and humidity inside the chamber.

[0015] This invention also discloses a circulating anther drying method based on temperature and humidity feedback air control, employing the circulating anther drying box based on temperature and humidity feedback air control as described in any one of claims 1 to 8, comprising: The anthers to be dried are laid flat in the anther tray and placed on the anther tray support of the anther tray support component. Start the drive device, and drive multiple sets of anther tray support parts through the transmission component to make the anther trays move up and down in a circular motion. During the circular motion, the anther trays remain horizontal under the action of gravity. Heat is generated by activating the heating device. Hot air enters the drying chamber through the first ventilation section, flows through the circulating anther tray, and then enters the exhaust chamber through the second ventilation section. The control module collects multi-point temperature data in the drying chamber through multiple temperature detection units, and adjusts the power of the heating device according to the temperature signal to maintain the temperature in the drying chamber within the set temperature range. The humidity of the exhaust gas is detected by the humidity detection unit, and the control module adjusts the exhaust volume of the exhaust device according to the humidity signal. After drying, remove the anther tray to collect the pollen.

[0016] As a further improvement of the present invention, the control module acquires multi-point temperature detection data of the upper, middle and lower parts of the drying chamber, and adjusts the output power of the heating device in a closed loop to keep the temperature in the drying chamber stable at 21~28℃.

[0017] As a further improvement of the present invention, the control module adjusts the exhaust volume of the exhaust device according to the exhaust humidity levels, so that the exhaust volume is positively correlated with the exhaust humidity: When the exhaust humidity is higher than the first humidity threshold, control the exhaust device to operate at the rated air volume. When the exhaust humidity is between the first humidity threshold and the second humidity threshold, the exhaust volume is controlled to decrease linearly as the exhaust humidity decreases. When the exhaust humidity is below the second humidity threshold, the exhaust device is controlled to operate at the minimum airflow.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, by setting up a circulating motion mechanism in the drying chamber, drives the anther tray support assembly to move the anther trays in an up-and-down circulating motion. This allows each tray of anthers to pass through different temperature zones in the drying chamber during the drying process, fundamentally eliminating the problems of temperature differences and uneven heating caused by rising hot air in traditional static drying. This ensures that the anthers in each tray are dried to a consistent degree, preventing some pollen from losing activity or even becoming inactive due to overheating, and significantly improving the quality and activity retention rate of the pollen. At the same time, the three-chamber design of heating chamber, drying chamber, and exhaust chamber, along with the bottom-in, top-out air duct design, allows hot air to enter from the bottom of the drying chamber and exit from the top, forming dynamic convection with the circulating anther trays, enhancing the heat exchange effect and improving drying efficiency.

[0019] This invention overcomes the shortcomings of traditional single-point temperature measurement, which suffers from poor representativeness and difficulty in accurately controlling the temperature inside the chamber, by setting up multiple temperature detection units in the drying chamber to collect multi-point temperature data. The control module adjusts the power of the heating device according to the multi-point temperature signals, enabling the temperature in the drying chamber to be accurately controlled below 28°C, thus avoiding the rapid loss of pollen activity caused by excessive temperature. At the same time, by setting up a humidity detection unit in the exhaust chamber to detect the exhaust humidity, the control module adjusts the exhaust volume of the exhaust device according to the humidity signal, so that the exhaust volume continuously decreases as the humidity of the anthers decreases. In the early stage of drying, a large air volume is maintained to enhance dehumidification, and in the pollen bursting stage, it automatically switches to a small air volume, effectively preventing the released pollen from being blown away by the large air volume, reducing the loss and waste of surface pollen.

[0020] This invention achieves dynamic circulating drying of the anther trays through a circulating motion mechanism. Combined with a large-capacity design with multiple anther tray support units spaced along the transmission chain, it significantly improves the drying capacity and heat exchange efficiency of a single machine. This solves the problem of low efficiency and inability to meet the needs of large-scale pollen production in traditional static drying, greatly improving the production efficiency and output of pollen production enterprises. The overall solution is reliable in structure and stable in operation. The anther tray support components are suspended by rotatable connectors and always remain horizontal under gravity, preventing them from flipping with the chain and ensuring the safety and reliability of the drying process.

[0028] In the above embodiments, preferably, a circulating motion mechanism 2 and multiple temperature detection units are provided inside the drying chamber 1-3.

[0029] like Figure 2-3 As shown, in the above embodiment, preferably, the cyclic motion mechanism 2 further includes a stabilizing bracket 2-1.

[0030] like Figure 2 As shown, in the above embodiment, preferably, the transmission assembly includes a driving sprocket 2-2, a driven sprocket 2-3, a transmission chain 2-4, and a transmission shaft 2-7. There is one driving sprocket 2-2 and three driven sprockets 2-3, with the four sprockets symmetrically arranged in pairs on two opposing rows of support columns 2-1-2 of the stabilizing bracket 2-1. Two sprockets on the same side are spaced vertically and connected by the transmission chain 2-4, which is located on both sides of the anther tray support assembly. Two sprockets located at the upper or lower part are synchronously connected via the transmission shaft 2-7, causing the two transmission chains 2-4 to operate synchronously. The driving sprocket 2-2 is connected to the drive motor 2-5 and is driven to rotate by the drive motor 2-5.

[0031] like Figure 2 , Figure 4 As shown, in the above embodiment, preferably, the anther tray support assembly includes multiple sets of anther tray support parts 2-6, which are spaced apart along the transmission chain 2-4. Each set of anther tray support parts 2-6 includes at least one anther tray support 2-6-1, a rotating connector 2-6-4, a connecting shaft 2-6-3, and a semi-circular connector 2-6-5. The anther tray support 2-6-1 supports the anther tray 2-6-2, in which anthers to be dried are laid flat. A rotating connector 2-6-4 is provided at each end of the anther tray support 2-6-1, and both ends of the connecting shaft 2-6-3 pass through the corresponding rotating connector 2-6-4, allowing the rotating connector 2-6-4 to rotate around the connecting shaft 2-6-3. Both ends of the connecting shaft 2-6-3 are fixedly connected to the corresponding semi-circular connector 2-6-5, and the semi-circular connector 2-6-5 is fixedly connected to the transmission chain 2-4. When the anther tray support 2-6-1 is multi-layered, the two ends of two adjacent anther tray supports 2-6-1 are fixedly connected at intervals by connecting supports 2-6-6.

[0032] In the above embodiments, preferably, the diameter of the semi-annular connector 2-6-5 is adapted to the diameter of the driving sprocket 2-2 and the driven sprocket 2-3.

[0033] In the above embodiment, preferably, the heating chamber 1-2 is equipped with a heating device 3 for generating the heat required for drying. The exhaust chamber 1-4 is equipped with an exhaust device 4 and a humidity detection unit 5. The exhaust device 4 is used to discharge moisture from the exhaust chamber 1-4, and the humidity detection unit 5 is used to detect the humidity of the exhaust. The heating device 3, the exhaust device 4, the multiple temperature detection units, and the humidity detection unit 5 are electrically connected to a control module, which can be integrated into a temperature and humidity control box 6. The control module is used to adjust the power of the heating device 3 according to the temperature signals from the multiple temperature detection units, and to adjust the exhaust volume of the exhaust device 4 according to the humidity signals from the humidity detection unit 5.

[0034] In the above embodiments, preferably, the exhaust device 4 is a plurality of exhaust fans arranged side by side on the top of the exhaust chambers 1-4, and the heating device 3 is a low-temperature heating device.

[0035] In the above embodiments, preferably, the control module can be a programmable logic controller (PLC) or a microcontroller, integrated into the temperature and humidity control box or set up in a separate control box.

[0036] like Figure 5 As shown, the circulating anther drying method based on temperature and humidity feedback control according to the present invention, using the above-mentioned circulating anther drying box based on temperature and humidity feedback control, includes the following steps: Step 1, Loading The anthers to be dried are laid flat in the anther tray 2-6-2 and placed on the anther tray support 2-6-1 of the anther tray support part 2-6 of the anther tray support assembly; specifically: The anthers to be dried are evenly spread in the anther tray 2-6-2, ensuring a uniform thickness. The anther tray 2-6-2 is then placed on the anther tray support 2-6-1 of the anther tray bearing part 2-6 of the circulating motion mechanism 2. If multiple anther tray supports 2-6-1 are used, anther trays 2-6-2 are placed on each layer, with adjacent layers maintained at a distance by connecting supports 2-6-6. The chamber door 1-5 is closed, and the drying parameters are set via the temperature and humidity control chamber 6.

[0037] Step 2: Start the cyclical exercise The drive unit is activated, and through the transmission assembly, multiple anther tray support units 2-6 are driven to move the anther trays 2-6-2 in an up-and-down cyclical motion. During this cyclical motion, the anther trays 2-6-2 remain horizontal under the influence of gravity. Specifically: Start the drive motor 2-5, which drives the drive sprocket 2-2 to rotate. The drive sprocket 2-2 drives the driven sprocket 2-3 on the same side to rotate via the transmission chain 2-4. Simultaneously, the drive chain 2-4 on the other side rotates synchronously via the transmission shaft 2-7, keeping the two transmission chains 2-4 synchronized. The multiple anther tray support parts 2-6 move up and down in a circular motion with the transmission chain 2-4, rising from the bottom to the top and then descending back to the bottom from the other side, forming a closed loop. During the circular motion, the rotating connector 2-6-4 can rotate freely around the connecting shaft 2-6-3. Under the action of gravity, the anther tray support 2-6-1 and the anther tray 2-6-2 always remain horizontal and will not flip with the transmission chain 2-4, ensuring that the anthers will not spill.

[0038] Step 3: Start heating and ventilation Heating device 3 generates heat, and hot air enters drying chamber 1-3 through first ventilation section 1-6, flows through the circulating anther trays 2-6-2, and then enters exhaust chamber 1-4 through second ventilation section 1-7; specifically: The heating device 3 is activated, generating heat within the heating chamber 1-2. Hot air enters the drying chamber 1-3 via the first ventilation section 1-6. In a preferred embodiment, the first ventilation section 1-6 is located at the lower part of the partition 1-1. Hot air enters from the lower part of the drying chamber 1-3, flowing upwards through the circulating anther disc 2-6-2, fully contacting the anthers for heat exchange. The humidified hot air enters the exhaust chamber 1-4 via the second ventilation section 1-7 and is discharged outside the chamber by the exhaust device 4.

[0039] Step 4: Precise temperature control at multiple points Multiple temperature detection units collect temperature data at various points within drying chambers 1-3. The control module adjusts the power of heating device 3 based on the temperature signals to maintain the temperature within drying chambers 1-3 within the set temperature range. Specifically: Multiple temperature detection units, located at the upper, middle, and lower parts of drying chambers 1-3, collect real-time temperature data from different locations within chambers 1-3 and transmit the temperature signals to the control module. The control module comprehensively assesses the actual temperature within drying chambers 1-3 based on the multi-point temperature data collected by the detection units and adjusts the power of heating device 3 to precisely control the temperature within chambers 1-3 below 28℃. When the detected temperature is too low, the control module increases the power of heating device 3; when the detected temperature is too high, the control module decreases or stops the power of heating device 3, ensuring that the temperature inside the chamber remains within the suitable low-temperature range for anther drying and preventing rapid loss of pollen viability due to excessive temperature.

[0040] Step 5: Humidity-adaptive airflow control The humidity of the exhaust gas is detected by the humidity detection unit 5, and the control module adjusts the exhaust volume of the exhaust device 4 according to the humidity signal; specifically: Humidity detection unit 5, located within exhaust chambers 1-4, monitors the exhaust humidity in real time and transmits the humidity signal to the control module. The control module determines the drying progress of the anthers based on the humidity data collected by the humidity detection unit 5 and adjusts the exhaust volume of the exhaust device 4, causing the exhaust volume to decrease continuously as the anther humidity decreases. In the initial drying stage, the anther moisture content is high, resulting in high exhaust humidity. The control module controls the exhaust device 4 to operate at a larger airflow to enhance dehumidification. As the drying process progresses and the anthers gradually dry, the exhaust humidity decreases, and the control module correspondingly reduces the exhaust volume of the exhaust device 4. When the anthers reach the pollen bursting stage, the exhaust humidity further decreases, and the exhaust volume automatically decreases to a lower level to prevent the large airflow from blowing away the released pollen, thus reducing pollen loss and waste.

[0041] Step 6: Discharge and collect powder After drying, remove the anther disc 2-6-2 to collect pollen; specifically: After the anthers have dried and cracked to release pollen, turn off the drive motor 2-5, heating device 3, and exhaust device 4, open the box door 1-5, take out the anther tray 2-6-2, and collect the pollen.

[0042] In the above embodiment, preferably, the control module acquires multi-point temperature detection data of the upper, middle and lower parts of the drying chamber 1-3, and adjusts the output power of the heating device 3 in a closed loop to keep the temperature in the drying chamber stable at 21~28℃.

[0043] In the above embodiment, preferably, the control module adjusts the exhaust volume of the exhaust device 4 according to the exhaust humidity levels, so that the exhaust volume is positively correlated with the exhaust humidity: when the exhaust humidity is higher than the first humidity threshold, the exhaust device 4 operates at the rated air volume; when the exhaust humidity is between the first humidity threshold and the second humidity threshold, the exhaust volume decreases linearly as the exhaust humidity decreases (e.g., by adjusting the speed of the exhaust fan to achieve linear adjustment of the exhaust volume); when the exhaust humidity is lower than the second humidity threshold, the exhaust device 4 operates at the minimum air volume. In this embodiment, the first humidity threshold and the second humidity threshold can be adjusted according to the anther variety and the ambient humidity, such as the first humidity threshold being set to 55%~65%RH and the second humidity threshold being set to 25%~35%RH.

[0044] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
