Abstract

This utility model discloses a dynamic rotary rapid drying device for tea, including a base. Two fixed frames are fixedly connected to the upper center of the base, and a drying cylinder is fixedly connected inside each frame. Connecting frames are fixedly connected to both ends of the upper part of the base. A motor is fixedly connected to the outer end of the right-side connecting frame. A slot is formed inside the right-side connecting frame, and a lead screw is rotatably connected inside the slot. The device uses a motor-driven gear set to rotate a cross-shaped rotating rod and a mesh cylinder, causing the tea leaves to continuously and dynamically tumble during the drying process. This rotary design significantly improves the uniformity of contact between hot air and tea leaves, avoiding localized overheating or under-drying, and ensuring uniform development of the tea's color and flavor.

Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a dynamic rotary rapid drying device for tea. Background Technology

[0002] Tea drying removes excess moisture, extends shelf life, and improves quality. Freshly picked leaves have a high moisture content and are prone to fermentation and spoilage if not processed promptly. Drying inhibits enzyme activity, prevents excessive oxidation, and preserves the color and flavor of the tea. Simultaneously, high-temperature drying removes grassy odors, enhances the tea aroma, and creates a unique taste. Different types of tea require controlled drying temperatures and times; for example, green tea requires high-temperature, rapid shaping, while black tea needs slow drying to promote sugar conversion. Drying also stabilizes the shape of the tea leaves, facilitating storage and transportation, and ultimately ensuring a clear tea liquor and a mellow flavor. It is an indispensable and crucial step in the tea-making process.

[0003] In existing tea drying technologies, static or semi-dynamic drying methods often result in uneven heating of the tea leaves. Especially when the tea leaves are piled up, the hot and humid air inside is difficult to expel effectively, which can easily cause localized steaming or scorching, affecting the color and aroma. At the same time, loading and unloading of fixed mesh cylinders requires frequent manual operation in a high-temperature environment, which poses a risk of burns and is inefficient. The connection structure between the mesh cylinder and the equipment is complex, and disassembly is time-consuming when changing batches. Utility Model Content

[0004] The purpose of this invention is to provide a dynamic rotary rapid drying device for tea, which solves the problem of uneven heating of tea often caused by static or semi-dynamic drying methods in the prior art.

[0005] To achieve the above objectives, a dynamic rotating rapid drying device for tea is provided, comprising a base, two fixed frames fixedly connected to the upper center of the base, a drying cylinder fixedly connected inside the fixed frames, connecting frames fixedly connected to both ends of the upper part of the base, a motor fixedly connected to the outer end of the right connecting frame, and a slot opened inside the right connecting frame, with a lead screw rotatably connected inside the slot.

[0006] The output end of the motor is fixedly connected to the lead screw. A threaded block is threaded onto the lead screw. A connecting column is fixedly connected to the inner end of the threaded block. A cover plate is fixedly connected to the inner end of the connecting column. A rotating frame is rotatably connected to the inner end of the cover plate. A mesh cylinder is correspondingly installed on the inner end of the rotating frame.

[0007] According to the aforementioned dynamic rotating rapid drying equipment for tea, the four ends of the rotating frame are fixedly connected to mounting blocks one, and the top four ends of the mesh cylinder are fixedly connected to mounting blocks two. The internal threads of mounting blocks one and mounting blocks two are fitted with positioning bolts.

[0008] According to the aforementioned dynamic rotary rapid drying equipment for tea, a sliding groove is provided at the inner end of the connecting frame on the left side, and a sliding rod is fixedly connected inside the sliding groove.

[0009] According to the aforementioned dynamic rotary rapid drying equipment for tea, a slider is slidably connected to the slide rod, and a connecting column is also fixedly connected to the other end of the slider, and the slider is connected to a threaded block.

[0010] According to the aforementioned dynamic rotary rapid drying equipment for tea, a heater is installed on the top of the drying cylinder.

[0011] According to the aforementioned dynamic rotary rapid drying equipment for tea, a drive box is fixedly connected to the tail end of the drying cylinder, and a rotating rod is rotatably connected to the middle of the drying cylinder through the drive box, with a gear fixedly connected to the rotating rod.

[0012] According to the aforementioned dynamic rotary rapid drying equipment for tea, a second motor is fixedly connected to one end of the inner side of the drive box, and a second gear is fixedly connected to the output end of the second motor, with the second gear meshing with the first gear.

[0013] According to the aforementioned dynamic rotary rapid drying equipment for tea, a support column is fixedly connected to the inner middle of the mesh cylinder, and a limiting groove is opened inside the support column, with the limiting groove corresponding to the rotating rod.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. This equipment uses a motor-driven gear set to rotate the cross-shaped rotating drum, causing the tea leaves to continuously and dynamically tumble during the drying process. This rotating design significantly improves the uniformity of contact between hot air and tea leaves, avoiding localized overheating or under-drying, and ensuring the uniform development of color and flavor in the tea. Simultaneously, the centrifugal force generated by the rotation promotes a loose distribution of the tea leaves, accelerating the diffusion of internal moisture outwards and shortening the drying cycle.

[0016] 2. In this equipment, the mesh cylinder and rotating frame are quickly locked together by mounting blocks and positioning bolts, forming a modular structure. During loading and unloading, they can be separated simply by tightening, which greatly reduces the intensity of manual operation. The translation component drives the cover plate and mesh cylinder to automatically enter and exit the drying cylinder through the screw drive. The sliding block mechanism ensures the stability of movement, eliminating the cumbersome process of manually moving the mesh cylinder in traditional drying. This design not only shortens the batch changeover time, but also avoids the risks of manual operation in high-temperature environments, significantly improving production continuity and safety. It is especially suitable for high-frequency, multi-batch tea processing operations.

[0025] 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.

[0026] Reference Figure 1-4 This utility model discloses a dynamic rotating rapid drying device for tea, including a base 1. Two fixed frames 2 are fixedly connected to the upper center of the base 1. A drying cylinder 11 is fixedly connected inside the fixed frame 2. Connecting frames 12 are fixedly connected to both ends of the upper part of the base 1. A motor 9 is fixedly connected to the outer end of the right connecting frame 12. A slot 6 is opened inside the right connecting frame 12. A lead screw 7 is rotatably connected inside the slot 6. The fixed frames 2 can fix the upper drying cylinder 11 to ensure the stability of the drying cylinder 11 during use. Secondly, the connecting frames 12 at both ends can support the translation component to ensure that the cover plate 4 can be translated. The mesh cylinder 3 can be stably fed into and out of the drying cylinder 11 before and after drying, improving its use effect and saving time and effort.

[0027] The output end of motor 9 is fixedly connected to lead screw 7. Threaded block 8 is threaded onto lead screw 7. Connecting column 5 is fixedly connected to the inner end of threaded block 8. Cover plate 4 is fixedly connected to the inner end of connecting column 5. Rotating frame 13 is rotatably connected to the inner end of cover plate 4. Mesh cylinder 3 is installed correspondingly on the inner end of rotating frame 13. The two can be locked together by mounting block 14, mounting block 2 15, and positioning bolt 16, so that mesh cylinder 3 is installed on rotating frame 13. Then, starting motor 9 can drive the internal lead screw 6 to rotate. Under the action of the threaded engagement, threaded block 8 can drive connecting column 5 and cover plate 4 to gradually retract inward, driving mesh cylinder 3 into the interior of drying cylinder 11, realizing the translation operation of mesh cylinder 3. After subsequent drying, it can also be automatically sent out for quick disassembly.

[0028] The rotating frame 13 is fixedly connected to four ends of mounting block 14, and the top of the mesh cylinder 3 is fixedly connected to four ends of mounting block 2 15. The internal threads of mounting block 14 and mounting block 2 15 are fitted with positioning bolts 16. The rotating frame 13 and the mesh cylinder 3 can be installed together through mounting block 14, mounting block 2 15 and positioning bolts 16, so as to facilitate the translation component to drive the mesh cylinder 3 to move. The lead screw 7 must be made of high temperature resistant alloy steel (such as stainless steel 304 / 316 or high temperature alloy). The threaded block 8 is made of high strength, wear-resistant and high temperature resistant engineering plastic. A long-term lubrication structure is designed on the lead screw 7, and a special high temperature (>150℃) resistant grease is used. The maintenance cycle of regular inspection and lubrication replenishment is required.

[0029] The inner end of the left connecting frame 12 is provided with a sliding groove 18. A sliding rod 17 is fixedly connected inside the sliding groove 18. A slider 19 is slidably connected on the sliding rod 17. The other end of the slider 19 is also fixedly connected to a connecting post 5. The slider 19 is connected to the threaded block 8. By setting the sliding rod 17, the sliding groove 18 and the slider 19 at the other end of the translation component, the stability of the entire net cylinder 3 during movement can be improved, and its use effect can be improved.

[0030] A heater 20 is installed at the top of the drying cylinder 11. A drive box 10 is fixedly connected to the tail of the drying cylinder 11. A rotating rod 23 is rotatably connected through the drive box 10 in the middle of the drying cylinder 11. A gear 21 is fixedly connected to the rotating rod 23. A motor 24 is fixedly connected to one end of the inner side of the drive box 10. A gear 22 is fixedly connected to the output end of the motor 24. The gear 22 meshes with the gear 21. A support column is fixedly connected to the middle of the inner side of the mesh cylinder 3. A limiting groove 25 is opened inside the support column. The limiting groove 25 corresponds to the rotating rod 23. When the cover plate 4 is completely sealed and closed, the heater 20 above can be activated to heat the drying cylinder 11, so that the tea leaves inside are dried. Then, the motor 24 is activated to drive the gear 22 to rotate. Under the meshing action, it can drive the gear 21 and the rotating rod 23 to rotate. The rotating rod 23 and the limiting groove 25 are connected in a cross shape, which can drive the entire mesh cylinder 3 to rotate dynamically, completing the dynamic rotation and rapid drying of the tea leaves. The four positioning bolts 16 are used in conjunction with nuts to improve the stability of the installation. On the end face where the cover plate 4 contacts the drying cylinder 11, an annular sealing groove is designed and a high-temperature resistant (>200℃), food-grade silicone or fluororubber sealing ring is embedded to ensure an effective seal when the cover plate is closed and locked. Secondly, the heater 20 uses a high-temperature resistant electric heating element. Its working principle is to convert electrical energy into heat energy through resistance heating, which is directly radiated and conducted to the cylinder wall and heats the internal air. During operation, the temperature sensor monitors the temperature inside the cylinder in real time and feeds it back to the control system. The heater power is dynamically adjusted through a PID algorithm to make the temperature accurately and stably maintain the set value required by the tea processing (such as 80-120℃).

[0031] Working principle: In use, tea leaves are placed inside the mesh cylinder 3. Then, the end of the mesh cylinder 3 is aligned with the rotating frame 13. The two are locked together by mounting block 14, mounting block 25, and positioning bolt 16, thus installing the mesh cylinder 3 on the rotating frame 13. Then, the motor 19 is started, which drives the internal lead screw 6 to rotate. Under the action of the threaded engagement, the threaded block 8 drives the connecting column 5 and the cover plate 4 to gradually retract inward, driving the mesh cylinder 3 into the drying cylinder 11. At the same time as the mesh cylinder 3 enters the drying cylinder 11, the rotating rod 23 can be inserted into the limiting groove 25. Both the rotating rod 23 and the limiting groove 25 are cross-shaped, which can perfectly lock together. When the cover plate 4 is completely sealed and closed, the heater 20 above can be activated to heat the drying cylinder 11, so that the tea inside is dried. Then, the motor 24 is activated to drive the gear 22 to rotate. Under the meshing action, the gear 21 and the rotating rod 23 can be driven to rotate. Since the rotating rod 23 and the limiting groove 25 are connected in a cross shape, the entire mesh cylinder 3 can be driven to rotate dynamically, so as to quickly dry the tea leaves. After the heating is stopped, the mesh cylinder 3 is kept rotating at a low speed for a period of time. The residual heat inside the cylinder and the rotation allow the moisture inside the tea leaves to diffuse further and cool down slowly. After the temperature drops to a safe range, the cover plate is opened and the mesh cylinder is removed. This can significantly improve the quality of the tea leaves.

[0032] 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.
