Technical Field
[0001] This utility model relates to the field of Eucommia ulmoides leaf blanching technology, specifically to an integrated blanching and drying equipment for Eucommia ulmoides leaves. Background Technology
[0002] In traditional Eucommia ulmoides leaf processing, the withering and drying stages are usually completed using separate equipment, which presents problems such as complex process connections, high energy consumption, and frequent manual intervention. For example, conventional withering equipment often relies on drum-type heat conduction or steam treatment, but the temperature control precision is insufficient, easily leading to uneven heating of the leaves and affecting the retention of effective components. The subsequent drying stage often uses static hot air or microwave drying, which has problems such as low drying efficiency and lag in humidity regulation, resulting in large fluctuations in leaf moisture content and inconsistent appearance quality. In addition, segmented operations require multiple material transfers, which not only increases the equipment footprint but also easily leads to secondary pollution or component loss due to environmental exposure. Although existing technologies have attempted to optimize single-stage equipment, we propose an integrated withering and drying equipment for Eucommia ulmoides leaves. Utility Model Content

[0025] Feeding assembly 4 includes a fixed frame 41, a feeding pipe 42, a spiral feeding strip 43, a fixed plate 44, a first motor 45, a gear 46, and a gear ring 47.

[0026] Wherein: the second temperature and humidity sensor (11) is bidirectionally electrically connected to an external PLC controller, and the input end of the first motor (45) is electrically connected to the output end of the external PLC controller.
[0027] The working principle of the integrated blanching and drying equipment for Eucommia ulmoides leaves provided by this utility model is as follows: When the feeding component 4 is started, the first motor 45 drives the gear 46 to mesh with the gear ring 47, which drives the feeding pipe 42 to rotate as a whole. The spiral feeding strip 43 fixed inside it continuously conveys the Eucommia ulmoides leaves from the left feed port to the inside of the fixed cover 3 through the spiral propulsion action. During this process, the air injection tank 52 of the air injection component 5 injects high-temperature steam into the feeding pipe 42 through the circumferentially distributed air outlet pipes 54. The first temperature and humidity sensor 53 collects the steam temperature and humidity data in real time. The opening and closing range of each first solenoid valve 55 is dynamically adjusted by the PLC controller to achieve precise control of the steam flow rate in the blanching stage, ensuring that the material is heated evenly. After the Eucommia ulmoides leaves have been blanched, they fall onto the surface of the conveyor belt 62 of the conveyor assembly 6 via the right end of the feeding pipe 42. The second motor 63 drives the conveyor rod 61 to move the belt to the right at a uniform speed. At the same time, the third motor 73 of the leveling assembly 7 drives the rotating shaft 71 to rotate the three sets of spreading plates 72. When the lower spreading plate 72 contacts the conveyor belt 62, it forms a scraping effect, spreading the accumulated material evenly into a single layer. During the drying stage, the hot air generated by the warm air blower 83 is introduced into the air outlet box 81 at the top of the fixed cover 3 and below the conveyor belt 62 through the second air outlet pipe 84 and the connecting pipe 85, respectively. The hot air forms a uniform hot air flow field through the strip exhaust port 82, drying the moving material on both sides. The second temperature and humidity sensor 11 inside the fixed cover 3 monitors the environmental parameters in real time, and links the exhaust fan 92 of the exhaust assembly 9 to adjust the exhaust rate. The second solenoid valve 93 controls the opening of the exhaust channel to dynamically remove the hot and humid air. Finally, the dried Eucommia leaves fall into the storage box 10 along the right end of the conveyor belt 62, realizing the fully automated continuous operation of the process of blanching, spreading, drying and collecting.
[0028] It is worth noting that the external PLC controller disclosed in the above embodiments is specifically a Siemens S7-200. The first motor 45, the second motor 63, the third motor 73, the first solenoid valve 55, the second solenoid valve 93, the heater 83, the exhaust fan 92, the first temperature and humidity sensor 53, and the second temperature and humidity sensor 11 can be freely configured according to the actual application scenario. The external PLC controller controls the operation of the first motor 45, the second motor 63, the third motor 73, the first solenoid valve 55, the second solenoid valve 93, the heater 83, and the exhaust fan 92 using methods commonly used in the prior art.
