[0023] In some embodiments, the circulating conveying device 4 includes a fixed frame 41, on which at least three conveying layers are provided. The conveying layers can be arc-shaped with an angle greater than 180°, which can extend the conveying path of the conveying layer and reduce the overall occupied space of the circulating conveying device 4; the conveying lengths of the three conveying layers gradually increase from top to bottom, and the conveying directions of the three conveying layers are opposite to adapt to the flow requirements of tea during the circulation process. An elevator 42 is connected between the head of the top conveying layer and the tail of the bottom conveying layer. The elevator 42 is existing technology and will not be repeated here. An S-shaped circulating conveying path is formed between the three conveying layers and the elevator 42. The conveying layer at the top is arranged below the feed plate 31 and is responsible for receiving the tea evenly dropped from the feed plate 31.

[0024] Specifically, the top conveying layer receives the tea leaves falling from the feeding plate 31, and is transported by the bottom conveying layer to the end of the top conveying layer, where the tea leaves naturally fall onto the next conveying layer until they fall onto the bottom conveying layer. The bottom conveying layer then transports the tea leaves in the opposite direction to the end of the bottom conveying layer, where the tea leaves naturally fall onto the elevator 42. The tea leaves rise under the action of the elevator 42 and naturally fall onto the top conveying layer from the top of the elevator 42, thus achieving the circular transportation of the tea leaves in the circular conveying device 4. During the circulation of the tea leaves, the tea leaves are heated and fragrant under the combined action of the heating device 5 and the air supply device. As the tea leaves circulate in the fixed drum 1, they move to different heated areas, thereby improving the uniformity of the heating of the tea leaves, thereby improving the consistency and overall quality of the tea leaves.

[0025] In some embodiments, the conveying layer includes a conveying motor 43, the output shaft of the conveying motor 43 is connected to a driving wheel 44, the driving wheel 44 is arranged at one end of the fixed frame 41, and a driven wheel 45 is provided at the other end of the fixed frame 41. A conveyor belt is connected between the driving wheel 44 and the driven wheel 45. The driving wheel 44 is driven by the conveying motor 43, and the driven wheel 45 is driven to rotate through the conveyor belt, thereby realizing the transportation of tea leaves. The conveyor belt can be a chain plate, and a plurality of ventilation holes are evenly distributed on the chain plate to facilitate hot air to penetrate the tea leaves and improve the heating effect.

[0026] In some embodiments, the feeding device 3 includes a fixed frame, a rotating motor mounted on the fixed frame, and a driving gear mounted on the output shaft of the rotating motor; a rotatable drum 32 mounted on the fixed frame, and a driven gear ring mounted on the drum 32. The driving gear meshes with the driven gear ring. The rotating motor drives the driving gear to rotate, and the meshed driven gear ring drives the drum 32 to rotate, thereby causing the tea leaves in the drum 32 to tumble, improving the uniformity of the tea leaves before heating, and preliminarily removing moisture from the tea leaves, thereby increasing the speed of tea aroma enhancement. The structure and specific principles of the rotating motor driving the drum 32 to rotate are prior art and will not be further described here; the discharge port of the drum 32 is located above the feed plate 31, and can guide the tea leaves thrown out of the drum 32 into the fixed drum 1. The discharge port of the drum 32 is provided with an adjustment device 6, which can adjust the size of the discharge port of the drum 32, thereby adjusting the discharge amount of tea leaves and ensuring the continuity and stability of the heating process.

[0027] In some embodiments, multiple spiral blades are evenly arranged inside the drum 32, which can make the tea leaves move in a set direction, helping the tea leaves to move smoothly, and multiple exhaust holes are provided on the drum 32 to enhance the flow of gas in the drum 32, discharge excess air and moisture, and avoid affecting the quality of the tea leaves.

[0028] In some embodiments, the adjusting device 6 includes a fixed plate 61, which is arranged on a fixed frame, and a movable plate 62 is provided on the fixed plate 61. The top of the movable plate 62 is connected to a driving block 63, and the driving block 63 is connected to the driving shaft of the adjusting cylinder. The adjusting cylinder is arranged on the top of the fixed frame; the driving block 63 is driven to rise and fall by the adjusting cylinder, thereby driving the movable plate 62 to rise and fall, and then the distance between the movable plate 62 and the fixed plate 61 is adjusted to achieve the adjustment of the size of the discharge port of the roller 32.

[0029] In some embodiments, the air supply device includes multiple air supply nozzles connected to an air pump. The multiple air supply nozzles are arranged in a ring shape at the bottom of the fixed drum 1, and the air supply direction of the air supply nozzles is toward the circulating conveying device 4, which can increase the heating rate of the tea leaves and accelerate the aroma of the tea leaves. The bottom of the fixed drum 1 is provided with a ventilation hole on the side away from the feed plate 31, through which moisture in the fixed drum 1 can be discharged. The structure and orientation of the air supply nozzles can be set according to the actual situation on site. This is a prior art and will not be described in detail here.

[0030] The specific working principle is as follows:

[0031] According to the type and demand of tea leaves, the size of the discharge port of the drum 32 is adjusted by the regulating device 6, the conveying speed of the circulating conveying device 4 is adjusted, the heating temperature of the heating device 5 and the air supply speed of the air supply device are adjusted.

[0032] The tea leaves enter the drum 32 , are driven by the drum 32 to rotate and are thrown out to the feeding plate 31 , and then slide from the feeding plate 31 to the top conveying layer of the circulating conveying device 4 .

[0033] Driven by the conveyor belt, the tea leaves move along the conveyor layers, descending layer by layer to the next, before ultimately being lifted to the topmost conveyor layer by elevator 42, forming a circular path. During this process, the heating device 5 heats the tea leaves, while the air supply device blows hot air onto the tea leaves through the air supply nozzles, accelerating the aroma enhancement process. After multiple cycles of heating, the tea leaves achieve the desired aroma enhancement effect and are then discharged through the gaps between the multiple conveyor layers.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
