Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea production technology, specifically to a tea drying device. Background Technology
[0002] Fresh tea leaves generally cannot be brewed directly and require a series of processing steps. Tea drying is one of the tea-making processes. The purpose of drying is threefold: first, to use high temperatures to destroy enzymes and stop enzymatic oxidation; second, to evaporate moisture, compress the tea leaves, and ensure the raw tea is fully dried to prevent non-enzymatic oxidation and maintain its quality; and third, to remove any grassy odor and further enhance and develop the aroma. Only dried tea leaves can bring out their color and flavor when brewed.
[0003] Traditional tea drying equipment uses hot air drying, which is inefficient. Currently, microwave drying is widely used, which not only dries faster but also allows for more continuous production and higher efficiency. However, in traditional microwave dryers, the tea leaves pass through the dryer statically without being turned or further evenly distributed, leading to uneven drying. Additionally, the evaporated water vapor increases the humidity inside the dryer, affecting the drying process. Further improvements are needed. Utility Model Content

[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0026] According to an embodiment of the present invention, a tea drying device is provided.
[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a tea drying device according to an embodiment of the present invention includes a microwave tea dryer body 1 and a conveyor belt 2. The microwave tea dryer body 1 has a drying chamber 3 inside, and the conveyor belt 2 is installed inside the microwave tea dryer body 1. This is a common structure in the art and will not be described in detail here. A first rotating rod 6 is rotatably connected above the conveyor belt 2 inside the drying chamber 3. Multiple sets of the first rotating rod 6 are arranged. A material-pulling rod 7 is fixedly installed on the surface of the first rotating rod 6, and a gas collecting hood 9 is fixedly mounted above the first rotating rod 6. A gas collecting pipe 11 is connected through the inlet. A vacuum pump 8 is fixedly installed on the top surface of the microwave tea dryer body 1, and the air inlet of the vacuum pump 8 is connected to the gas collecting pipe 11 through the vacuum pipe 10. A second rotating rod 12 is rotatably connected inside the microwave tea dryer body 1, located inside the conveyor belt 2. Multiple sets of the second rotating rod 12 are arranged, and a head 19 is connected to the surface of the second rotating rod 12 through a striking rod 18. A diversion pipe 13 is installed inside the microwave tea dryer body 1, located inside the conveyor belt 2, on one side of the second rotating rod 12, and a blowhole is connected through the surface of the diversion pipe 13. Multiple sets of diversion pipes 13 and blowing nozzles 20 are arranged. During tea drying, the tea leaves can be laid on the top surface of the conveyor belt 2 by a vibrating feeder. The conveyor belt 2 transports the tea leaves into the drying chamber 3 of the main body 1 of the microwave tea dryer for microwave drying. During microwave drying, the first rotating rod 6 and the second rotating rod 12 rotate under the drive of the first drive motor 14 and the second drive motor 15, respectively, driving the feeding rod 7 and the striking head 19 to rotate. The rotating feeding rod 7 disperses and turns the tea leaves, and the striking head 19 strikes the conveyor belt 2, improving the drying efficiency of the tea leaves. The vibration effect improves the turning efficiency, thereby increasing the overall turning efficiency, improving the uniformity of microwave drying of tea leaves, and improving work efficiency. At the same time, during drying, the blower 16 and the vacuum pump 8 are started. The air generated by the blower 16 flows into the air supply pipe 17 and is blown out through the nozzle 20 to form a vertical airflow. The vacuum pump 8 is started, and the airflow carrying the evaporated water vapor quickly enters the air collection hood 9 and is extracted by the vacuum pump 8, completing the rapid discharge of water vapor, reducing the humidity inside the drying chamber 3, thereby accelerating the drying process and further improving work efficiency.
[0028] In one embodiment, a first drive motor 14 and a second drive motor 15 are fixedly installed on the front of the main body 1 of the microwave tea dryer, and the output ends of the first drive motor 14 and the second drive motor 15 are respectively fixedly connected to one end of the first rotating rod 6 and the second rotating rod 12, which is a common drive structure.
[0029] In one embodiment, a blower 16 is fixedly mounted on the rear of the main body 1 of the microwave tea dryer, and the output end of the blower 16 is connected to the distribution pipe 13 through the air supply pipe 17, which is a common air supply structure. The blower 16 is a small blower 16 with adjustable air flow to avoid excessive air flow speed causing the tea leaves to scatter.
[0030] In one embodiment, an inclined plate 4 is fixedly installed inside the main body 1 of the microwave tea dryer below the conveyor belt 2, and a scrap drawer 5 is placed below the bottom opening of the inclined plate 4. The scrap drawer 5 penetrates the front facade of the main body 1 of the microwave tea dryer, which facilitates the collection of tea leaves that have passed through the conveyor belt 2 for secondary processing.
[0031] In one embodiment, multiple sets of material-pulling rods 7 are distributed at equal angles along the central axis of the first rotating rod 6, and multiple sets of material-pulling rods 7 are evenly spaced along the length direction of the first rotating rod 6. Both the material-pulling rods 7 and the first rotating rod 6 are made of ceramic material, which is safer.
[0032] In one embodiment, the distance between the second rotating rod 12 and the inner surface of the top of the conveyor belt 2 is less than the total length of the striking rod 18 and the striking head 19, and multiple sets of striking head 19 and striking rod 18 are arranged. The second rotating rod 12, striking head 19 and striking rod 18 are all made of ceramic material, which is safer.
[0033] In one embodiment, multiple sets of gas collection hoods 9 are arranged, and the gas collection hoods 9 have an inverted funnel-shaped structure. The gas collection hoods 9, gas collection pipes 11, diversion pipes 13 and nozzles 20 are all made of non-metallic materials, which makes them safer.
[0034] Working Principle: During tea drying, the tea leaves are laid on the top surface of the conveyor belt 2 using a vibrating feeder. The conveyor belt 2 then transports the tea leaves into the drying chamber 3 of the microwave tea dryer body 1 for microwave drying. During microwave drying, the first rotating rod 6 and the second rotating rod 12 rotate under the drive of the first drive motor 14 and the second drive motor 15, respectively, which in turn drives the feeding rod 7 and the striking head 19 to rotate. The rotating feeding rod 7 disperses and turns the tea leaves, while the striking head 19 strikes the conveyor belt 2, enhancing the vibration effect of the tea leaves and improving drying efficiency. The turning efficiency is improved, thereby increasing the overall turning efficiency, improving the uniformity of microwave drying of tea leaves, and improving work efficiency. At the same time, during the drying process, the blower 16 and the vacuum pump 8 are started. The air generated by the blower 16 flows into the air supply pipe 17 and is blown out through the nozzle 20 to form a vertical airflow. The vacuum pump 8 is started, and the airflow carrying the evaporated water vapor quickly enters the air collection hood 9 and is extracted by the vacuum pump 8, completing the rapid discharge of water vapor, reducing the humidity inside the drying chamber 3, thereby accelerating the drying process and further improving work efficiency.
