[0025] The bottom of the housing 11 is provided with an opening for installing an electromagnetic heating coil 21, which is located below the drum 10 and fixed to the bottom plate 14 through a bracket. The electromagnetic heating coil 21 is connected to an electromagnetic control system and a power supply, and the drum 10 is made of magnetic material, such as carbon steel, iron, stainless iron, seamless steel pipe, etc. The temperature of the heating coil is adjusted by the electromagnetic control system, and the heating can be turned off or started at any time; all of the above are commercially available and are prior art.
[0026] Figure 3 In the embodiment, springs 39 are installed at the four corners of the top of the feed bracket 36, the top of the spring 39 is connected to the vibration plate 40, a camshaft 37 is arranged below the vibration plate 40, the camshaft 37 is installed on the feed bracket 36 through a bearing, a second driven wheel 35 and a cam 38 are installed on the camshaft 37, the second driven wheel 35 is connected to the transmission assembly, the cam 38 abuts against the bottom of the vibration plate 40, and the cam 38 intermittently lifts the vibration plate 40 during the rotation process, so that the vibration plate 40 generates periodic vibration. The vibration plate shakes the tea leaves above and feeds the tea leaves into the feed port 15 of the drum 10.

[0029] It should be noted that the vibration plate 40 is tilted, and one end of the vibration plate 40 adjacent to the drum 10 is lower than the other end. The vibration plate 40 is arranged in a high-low manner, which is conducive to the tea leaves entering the vibration plate 40 smoothly.
[0030] Both ends of the drum 10 are fixedly provided with a conducting ring 22, and two supporting wheels 18 are symmetrically mounted on the bottom of the conducting ring 22. When the drum 10 is driven by an external rotating force in the axial direction, the drum 10 rotates on the four supporting wheels 18.
[0031] Six guide vanes 12 are fixedly arranged on the inner wall array of the drum 10. The guide vanes 12 adopt a spiral structure, which can prolong the contact time between the tea leaves and the inner wall of the drum 10, and make the tea leaves in the drum 10 dispersed more evenly during the rotation of the drum 10.
[0032] Figure 1-Figure 2 In the figure, a vent 17 is installed on the top of the shell 11. A large amount of high-temperature gas will remain in the gap between the drum 10 and the shell 11. A fan (not shown in the figure) is installed at the vent 17. The high-temperature airflow collected by the vent 17 is collected through a pipeline and then introduced into the withering drum 10 (not shown in the figure), so as to fully utilize the heat and ensure the color of the tea soup through two-way heating.
[0033] The transmission assembly includes a second sprocket 32 disposed on the barrel neck 19, a motor 23 fixed on the bottom plate 14, a support seat 28 is installed on one side of the motor 23, a rotating shaft 25 is installed on the support seat 28, a first sprocket 31, a driving wheel 24 and a first driven wheel 34 are sequentially installed on the rotating shaft 25, an output end of the motor 23 is connected to the driving wheel 24 through a first belt 26, the first sprocket 31 is connected to the second sprocket 32 through a chain 33, and the first driven wheel 34 is transmitted to the second driven wheel 35 through a second belt 27.

[0035] The transmission assembly is transmitted to the second sprocket 32 through the first sprocket 31 , so that the barrel neck 19 fixedly connected to the second sprocket 32 rotates, thereby driving the drum 10 to rotate on the four supporting wheels 18 .
[0036] The transmission assembly transmits power to the second driven wheel 35 through the first driven wheel 34, so that the cam 38 on the camshaft 37 rotates, and the cam 38 acts on the vibration plate 40 to generate vibration.
[0037] Working principle:
[0038] The electromagnetic heating coil 21 is turned on, and the motor 23 is turned on. The motor 23 is driven to the driving wheel 24 through the first belt 26. The driving wheel 24 and the first driven wheel 34 and the first sprocket 31 rotate coaxially. The first driven wheel 34 is driven to the second driven wheel 35 through the second belt 27. The second driven wheel 35 rotates coaxially with the cam 38. The cam 38 intermittently lifts the vibration plate 40 to make it vibrate. The vibration disperses the tea leaves on the guide plate 42 and then guides them into the feed port 15.
[0039] The first sprocket 31 is transmitted to the second sprocket 32 through the chain 33, and the second sprocket 32 drives the drum 10 to rotate. After the drum 10 withers the tea leaves inside, the tea leaves are discharged from the discharge port 16. During the working process, the surface moisture or impurities separated from the tea leaves are discharged to the cleaning plate 43 on the lower layer, and the cleaning plate 43 is pulled out for cleaning and then put into use.
