[0034] Please refer to Figures 1 to 10 The withering machine in the figure is mainly designed with components such as a warehouse body 1, a surface cooler 2, a uniform fan 3, an air supply box 4, a fresh air valve 5, an internal circulation air valve 6, and a wet curtain 7. The warehouse body 1 is mainly used as an overall frame structure, which is convenient for installing and fixing other components. The surface cooler 2 is used to adjust the temperature in the warehouse body 1, and the uniform fan 3 is used to generate a large air volume to keep the wind pressure in the warehouse body 1 as uniform as possible at all positions. The air supply box 4 is used for exhaust or withering internal circulation, the fresh air valve 5 is used for fresh air to enter the warehouse body 1, the internal circulation air valve 6 is used for the withering internal circulation of the warehouse body 1, and the wet curtain 7 is used to adjust the humidity of the warehouse body 1. In actual applications, the above components can be further optimized or other components can be added or existing components can be used for equivalent replacement.

[0035] The storage body 1 in the figure is a box-type frame structure as a whole, which can be made of a structure of an insulation board and a steel frame. The storage body 1 can be designed with an air inlet and an air outlet, so as to facilitate the entry of fresh air and the discharge of gas during the withering process. For example, the air inlet can be designed near the air distributor 3, and the air outlet can be designed near the air supply box 4. In order to facilitate the installation of the fresh air valve 5, the fresh air outlet 12 for installing the fresh air valve 5 can be designed at the corresponding position. As shown in the figure, three horizontally aligned fresh air outlets 12 are designed on the top of the storage body 1. In order to facilitate the transportation of the withering rack 10 and to facilitate the installation and maintenance of the air distributor 3 or the surface cooler 2, a storage door 11 with an opening and closing structure can be designed at the corresponding position. The interior of the above-mentioned storage body 1 is designed with multiple partitions in sequence according to the direction of fresh air entering so as to correspond to different environments. For example, the air inlet chamber 13, the withering chamber 14, the air outlet chamber 15, and the reflux chamber 16 are designed according to the air intake, withering, air outlet, and reflux conditions. The air inlet chamber 13 is used to form an air inlet space for placing the surface cooler 2 and the air distributor 3, the withering chamber 14 is used to form a withering space for placing the withering rack 10, the air outlet chamber 15 is used to form an exhaust space for placing the air supply box 4 and the internal circulation air valve 6, and the reflux chamber 16 is located at the top position of the other three chambers for forming an internal circulation reflux space and is designed with a wet curtain 7 near the surface cooler 2 and the air distributor 3. In actual applications, the above-mentioned chambers can be further divided or re-optimized.

[0036] The surface cooler 2 in the figure adopts the existing structure, which uses water as the heat exchange medium. The surface cooler 2 is arranged with fins to improve the heat exchange effect. The surface cooler 2 is a frame structure as a whole and the overall size is kept consistent with the uniform air blower 3 and the number is also consistent, so as to improve the temperature regulation effect of the withering machine. At the same time, the two ends of the surface cooler 2 are designed with an inlet pipe 91 and an outlet pipe 92 for facilitating the flow of water. The inlet pipe 91 and the outlet pipe 92 are connected to the matching temperature regulation component, so as to adjust the heat dissipation of the surface cooler 2 in real time, thereby adjusting the temperature of the withering chamber. Three sets of surface coolers 2 are used in the figure, and each set of surface coolers 2 is assembled with the temperature regulation component through the main pipeline and the branch pipeline.

[0037] The uniform air blower 3 in the figure is a low-speed silent blower, which is relatively large in size and corresponds to the size of the surface cooler 2 and the air inlet chamber 13. Three horizontally aligned uniform air blowers 3 are designed in the figure. Through the low-speed and large-volume configuration, sufficient air volume can be provided to the withering chamber 14, so that the wind pressure at various places in the withering chamber 14 can be made as consistent as possible.

[0038] The air supply box 4 in the figure is a conventional frame structure, on which there are air uniforming plates 41 which are symmetrically arranged and perforated and hollowed out. For example, plum blossom holes with a diameter of 3-4 mm are designed as perforations, so that the amount of exhaust air and the exhaust path are adjusted. An exhaust path is formed inside the air supply box 4 and cooperates with the air uniforming plates 41, thereby forming an exhaust effect like a chimney.

[0039] The internal circulation air valve 6 in the figure is a conventional component and is located on the top of the air supply box 4. When the entire device needs to perform internal circulation, it opens the return air path and cuts off the exhaust air path, so that the device performs internal circulation operation. When exhausting, it is in a closed state.

[0040] The fresh air valve 5 in the figure is a conventional component, which can serve as an inflow channel for external air flow to enter the withering machine. As shown in the figure, three fresh air valves 5 are installed horizontally on the top of the storage body 1.

[0041] The temperature regulating component in the figure is designed with components such as a cold water tank 81, a hot water tank 82, and a heat pump 83, and the whole is also a conventional temperature regulating component, which provides the withering machine with low-temperature and high-temperature heat exchange media. The cold water tank 81 is used to store cold water, the hot water tank 82 is used to store hot water, and the heat pump 83 is used to store energy to avoid energy waste, thereby improving the regulation effect of the entire temperature regulating component.

[0042] The working method of the withering machine in this case is: first place the fresh leaves on the withering rack 10, push the withering rack 10 into the withering chamber 14, close the door 11, send the high-temperature or low-temperature heat exchange medium into the surface cooler 2, and at the same time, the uniform fan 3 starts to work, open the internal circulation air valve 6 and the new air valve 5, and the wet curtain 7 allows natural water to provide sufficient humidity to maintain a certain period of internal circulation withering operation, that is, the outside air flows through the air inlet chamber 13, the withering chamber 14, the air outlet chamber 15, the reflux chamber 16 in turn and then returns to the air inlet chamber 13. After the above is completed, close the internal circulation air valve 6, the uniform fan 3 continues to work, and the withering machine performs exhaust operation, that is, it is directly discharged from the air outlet chamber 15 and no longer enters the reflux chamber 16.
