[0002] Dynamic tea dryers, as important tea-making machinery, play a vital role in improving tea quality and yield during tea production and processing. Existing drying devices typically place tea leaves in a drying room or oven, which leads to tea leaves accumulating in the center of the oven and becoming difficult to dry, resulting in uneven drying.
[0003] A Chinese patent application with patent number "CN202322282563.1" entitled "A Dynamic Tea Dryer" includes: a drying cylinder with a feeding hopper at the top and a discharge port on the outer wall of the drying cylinder; a transmission assembly including a vertically arranged rotating shaft inside the drying cylinder, and a drying plate and an air-drying plate connected sequentially from top to bottom on the rotating shaft, with a guide plate between the drying plate and the air-drying plate for receiving tea leaves falling from the drying plate and placing them on the air-drying plate; a motor connected to one end of the rotating shaft for driving the rotating shaft to rotate; a heating assembly located at the bottom of the drying plate for heating the drying plate; and an air inlet assembly located at the bottom of the drying cylinder for delivering airflow from bottom to top. However, this device still has the following problems in use:
[0004] 1. Tea leaves are of different sizes. When the comb teeth turn them over, the evenly distributed openings of the comb teeth can easily cause the tea leaves to split, resulting in a decline in tea quality.
[0005] 2. In this device, both the drying plate and the air-drying plate are umbrella-shaped, which facilitates the feeding of tea leaves. However, during use, the tea leaves on the drying plate and the air-drying plate are not easy to adhere to and are prone to falling off during rotation, resulting in the tea leaves on the outer side not being dried thoroughly. Utility Model Content
[0006] The purpose of this invention is to provide a dynamic tea drying machine that solves the problems mentioned above.
[0007] To achieve the above objectives, a dynamic tea drying machine is provided, comprising a base, a support rod fixedly connected to the upper side of the base, an mounting block fixedly connected to the upper end of the support rod, and a drying mechanism provided between the two mounting blocks; the drying mechanism includes a drying cylinder, a first mounting plate and a second mounting plate fixedly connected to both ends of the drying cylinder, each mounting block consisting of a drive block and a fixing block, a drive motor being provided inside the drive block, a drive rod fixedly connected to the output end of the drive motor, one end of the drive rod passing through the first mounting plate and the other end rotatably connected to the second mounting plate, the drive block being fixedly connected to the first mounting plate, the fixing block being fixedly connected to the second mounting plate, a rotating cylinder fixedly connected to the drive rod located inside the drying cylinder, a baffle fixedly connected inside the rotating cylinder, a drying device fixedly connected to the upper side of the base, a pipe fixedly connected to the output end of the dryer, and the other end of the pipe fixedly connected to the drying cylinder.
[0008] According to the aforementioned dynamic tea drying machine, the drying cylinder is hinged with a cover plate, and the inner bottom is provided with an inclined section.
[0009] According to the aforementioned dynamic tea drying machine, the pipeline is configured as a three-pipe system, and a filter screen is provided at one end located inside the drying cylinder.
[0010] According to the aforementioned dynamic tea drying machine, the second mounting plate is provided with an air outlet pipe and a discharge port on the right side, the air outlet pipe being located on the upper side of the fixed block and the discharge port being located on the lower side of the fixed block.
[0011] According to the aforementioned dynamic tea drying machine, the rotating drum is cylindrical in shape, and the upper part of the rotating drum is hinged and connected by a locking mechanism.
[0012] According to the aforementioned dynamic tea drying machine, there are several baffles arranged in a ring.
[0013] This utility model has the following beneficial effects:
[0014] 1. Compared with existing technologies, by installing a rotating drum and a baffle inside the drying drum, the tea leaves are lifted to a high position and fall at the critical point. During the fall, the dryer blows the tea leaves apart, resulting in a better drying effect. After drying, the drying drum and rotating drum are opened and the tea leaves are taken out.
[0015] 2. Compared with existing technologies, by providing an inclined section at the bottom of the drying drum, the fine tea leaves produced during the drying process will slide to the discharge port and be discharged, thereby improving the overall yield and quality of the tea.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0024] Reference Figure 1-4 This utility model embodiment provides a dynamic tea drying machine, which includes a base 1. The base 1 is made of a sturdy and durable metal material, with good load-bearing capacity and stability, which can ensure that the entire equipment runs smoothly and reliably and will not shake or shift due to vibration or other external forces. A support rod 2 is fixedly connected to the upper side of the base 1, and an installation block 3 is fixedly connected to the upper end of the support rod 2. A drying mechanism 4 is provided between the two installation blocks 3.
[0025] The drying mechanism 4 includes a drying cylinder 41, which is made of stainless steel and has an internal heat insulation layer. A cover plate 42 is hinged to the drying cylinder 41, and an inclined part 45 is provided at the bottom. The design of the inclined part 45 helps the tea debris generated during the drying process to slide off and be discharged naturally, avoiding the accumulation and blockage of tea inside the cylinder. The cover plate 42 is made of transparent acrylic material, which makes it easy to observe the tea. A first mounting plate 43 and a second mounting plate 44 are fixedly connected to both ends of the drying cylinder 41, respectively. Both the first mounting plate 43 and the second mounting plate 44 are disc-shaped. An air outlet 441 and a discharge port 442 are provided on the right side of the second mounting plate 44. The air outlet 441 is located on the upper side of the fixed block 32, and the discharge port 442 is located on the lower side of the fixed block 32. The air outlet 441 is used to discharge the hot and humid air generated during the drying process, thereby improving the drying efficiency. During drying, because the bottom of the drying cylinder 41 is inclined, the fine tea debris will slide to the discharge port 442 and be discharged, thereby improving the overall yield and quality of the tea.
[0026] Mounting block 3 consists of a drive block 31 and a fixing block 32. The drive block 31 houses a drive motor, which is meticulously designed according to the overall power requirements and operational needs of the dryer to ensure stable and sufficient power output. A drive rod 7 is fixedly connected to the output end of the drive motor. One end of the drive rod 7 passes through the first mounting plate 43, and the other end is rotatably connected to the second mounting plate 44. The drive block 31 is fixedly connected to the first mounting plate 43, and the fixing block 32 is fixedly connected to the second mounting plate 44.
[0027] A rotating cylinder 6 is fixedly connected to the drive rod 7 inside the drying cylinder 41. The rotating cylinder 6 is cylindrical in shape, with its upper part hinged and connected by a locking mechanism. This facilitates the loading and unloading of tea leaves. The locking mechanism ensures the stability of the rotating cylinder 6 during operation, preventing it from loosening or falling off due to vibration or other reasons. Several baffles 61 are fixedly connected inside the rotating cylinder 6, arranged in a ring. During the rotation of the rotating cylinder 6, the baffles 61 stir and agitate the tea leaves, ensuring they are fully in contact with the hot air inside the drying cylinder 41 for uniform drying. The shape, size, and spacing of the baffles 61 are carefully designed and optimized to effectively stir the tea leaves without causing excessive damage, thus ensuring the quality and integrity of the tea.
[0028] A drying device 5 is fixedly connected to the upper side of the base 1. A pipe 51 is fixedly connected to the output end of the drying device 5. The other end of the pipe 51 is fixedly connected to the drying cylinder 41. The pipe 51 is a three-way connection, and a filter screen is provided at one end inside the drying cylinder 41. Under the action of the pipe 51, hot air can be more evenly distributed to different parts of the drying cylinder 41, further improving the uniformity of drying. At the same time, the filter screen can filter out impurities and dust in the air, preventing them from entering the drying cylinder 41 and affecting the quality and hygiene of the tea.
[0029] Working principle: When in use, place the tea leaves in the rotating drum 6 and start the drive motor in the drive block 31. Under its action, the drive rod 7 and the rotating drum 6 will rotate. At the same time, the drying equipment 5 will be started. The drying equipment 5 dries the tea leaves through the pipe 51. At this time, under the action of the baffle 61 in the rotating drum 6, the tea leaves will be carried to a high place and fall at the critical point. During the falling process, the tea leaves will be dried and blown apart to make the drying effect better. After drying, open the drying drum 41 and the rotating drum 6 and take out the tea leaves.
[0030] During drying, the fine tea leaves can be sieved out by rotating drum 6 and fall into drying drum 41. Since the bottom of drying drum 41 is designed to be inclined, the fine tea leaves will slide to the discharge port 442 and be discharged, thereby improving the overall yield and quality of tea.
[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
