Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, and in particular to a tea drying device with a rotating hot air guide plate. Background Technology

[0002] In tea processing, fixation and drying are two crucial steps that determine tea quality. Fixation requires rapidly deactivating the oxidases in fresh leaves at high temperatures (280-320℃) to inhibit the enzymatic oxidation of tea polyphenols, while simultaneously removing a grassy odor and promoting the formation of a pleasant aroma. Drying, on the other hand, requires evaporating the moisture content of the tea leaves to 5%-7% under medium-temperature conditions (100-140℃) to fix the tea's quality. However, because tea is extremely sensitive to temperature changes, excessively high fixation temperatures or uneven heating can easily lead to quality defects such as scorched edges, dark yellow color, or red stems and leaves. Existing processing equipment mainly relies on drum turning or static drying on mesh screens, but it is difficult to achieve comprehensive control that integrates non-contact, uniform fixation, efficient energy circulation, and fixation and drying.

[0003] Chinese patent CN203388194U discloses a tea fixing device that uses a rotating fixing cylinder in conjunction with a hot air furnace to fix and dry tea leaves. This solution can meet the fixing needs of general tea, but it only provides overall temperature control, lacks a tiered flow guiding structure, and cannot dynamically adjust according to the heating differences in different areas. Furthermore, the tea leaves are in direct contact with the high-temperature cylinder wall inside the rotating cylinder, easily resulting in scorched edges, and it lacks a precise control mechanism for the uniformity of heating the tea leaves.

[0004] For example, Chinese patent CN201720741238.9 discloses a novel tea fixing device that uses an electric heating plate for heating and a spiral blade conveyor to fix the tea leaves. Although the system is equipped with temperature feedback regulation, it still uses contact heat transfer between the tea leaves and the heating plate, and can only achieve unidirectional conveying. It does not consider the tumbling and suspending of the tea leaves in space for heating, and it also lacks an integrated design for fixing and drying, resulting in low equipment utilization.

[0005] In addition, the following defects still exist in the existing technology: 1. Most withering devices use drums or woks, where tea leaves come into direct contact with a hot metal surface, resulting in a scorching rate of 4%-6%. Furthermore, the temperature is difficult to control precisely, which can easily lead to localized overheating or insufficient withering. 2. Although traditional airflow drying equipment can suspend tea leaves, the high-speed airflow will take away the heat of the tea leaves, resulting in insufficient fixation temperature. Moreover, the breakage rate of tea leaves in the high-speed airflow is as high as 8%-12%, making it difficult to maintain the integrity of the tea leaves. 3. The existing equipment for fixing and drying is separate, and the tea leaves need to be transferred between the two processes. This not only increases the risk of contamination and breakage, but also results in large equipment investment, large floor space, and high energy consumption (comprehensive energy consumption reaches 1.8-2.2 kWh / kg dry tea). 4. Traditional equipment often has an open-loop hot air circulation system, resulting in significant heat loss and a thermal efficiency of only 60%-65%. Furthermore, it lacks a closed-loop energy management system that integrates temperature control, uniform heating, and energy recovery. 5. In the processing of high-end premium teas, there is still a lack of integrated processing equipment that can simultaneously achieve non-contact uniform fixation, tea leaf tumbling and heating, integrated fixation and drying, intelligent temperature transition control, and efficient heat energy circulation.

[0006] This utility model was developed to address common problems in the field, such as high scorching rate during fixation, severe tea breakage, separation during fixation and drying, high energy consumption, and uneven heating. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of current methods by proposing a tea drying device with a rotating hot air guide plate.

[0008] In order to overcome the shortcomings of the existing technology, the present invention adopts the following technical solution: A tea drying device with a rotating hot air guide plate includes a feeding chamber, a tilting component, a throwing component, and a hot air guide component. The feeding chamber has an inner cavity and an outer cavity. The outer cavity is disposed on the outer periphery of the inner cavity. The throwing component is disposed in the inner cavity. The tilting component is disposed outside the throwing component and adjusts the posture of the throwing component. The hot air guide component is disposed in the outer cavity and pumps drying hot air toward the throwing component. The material throwing component includes a placement plate, a conical throwing disc, a throwing drive motor, and an isolation storage net. The placement plate is symmetrically arranged at both ends of the isolation storage net. The throwing drive motor is driven and connected to the conical throwing disc to form a throwing section. The throwing section is symmetrically arranged on the placement plate. The isolation storage net surrounds the periphery of the placement plate to form a drying chamber for placing tea leaves.

[0009] Optionally, the conical throwing disc has radial throwing ribs on the contact side with the tea leaves, and the throwing ribs are spirally distributed along the center of symmetry of the conical throwing disc.

[0010] Optionally, the surface of the throwing rib is provided with micro-protrusions.

[0011] Optionally, the isolation storage net is equipped with a tea inlet and an electronic shut-off valve. The tea inlet has a tea channel communicating with the isolation storage net, and the electronic shut-off valve is located in the tea channel.

[0012] Optionally, the flipping component includes a flipping track, a fixed seat, and a locking component. The fixed seat is disposed on the outer wall of the first and last ends of the isolation storage net. The fixed seat is provided with a connecting protrusion. The connecting protrusion is slidably connected to the flipping track. The locking component is disposed at the upper and lower positions of the flipping track and locks the connecting protrusion that enters the upper and lower positions.

[0013] Optionally, the flipping track is set to be circular.

[0014] Optionally, a hot air guiding component is disposed on the outer layer of the isolation storage mesh and performs a drying operation on the tea leaves stored in the drying chamber of the isolation storage mesh.

[0015] Optionally, the hot air guiding component includes a multi-layer rotating guide plate, a guide plate driving mechanism, and a heater group. The multi-layer rotating guide plates are arranged at intervals in the outer cavity along the vertical direction. Each rotating guide plate is provided with a heating device. The guide plate driving mechanism is driven and connected to the rotating guide plate. The heater group is located at the bottom of the outer cavity and is used to heat the circulating hot air.

[0016] Optionally, the locking component includes an electromagnetic lock and a limiting slot. The limiting slot is disposed at the upper and lower positions of the flipping track. The electromagnetic lock controls the connecting protrusion to enter or leave the limiting slot. The electromagnetic lock is disposed on the connecting protrusion and is disposed on one side facing the limiting slot.

[0017] Optionally, the inner cavity and the outer cavity are separated by a perforated plate.

[0018] The beneficial effects achieved by this utility model are: 1. Through the cooperation of the feeding chamber and the throwing component, the tea leaves can be evenly distributed in the drying chamber and initially turned over, ensuring that the entire device can be evenly heated during the tea feeding and drying process. This effectively avoids the scorching of the tea leaves due to accumulation or excessive concentration, and ensures the uniformity of heating of the tea leaves throughout the drying process. 2. Through the efficient cooperation of the hot air guiding component and the material throwing component, the hot air can be evenly distributed in the drying chamber, and the tea leaves can fully contact the hot air. This avoids the phenomenon of local overheating or underheating that is common in traditional drying equipment. At the same time, it improves the uniformity of drying, solves the problem of uneven heating mentioned in the background technology, ensures that the drying effect of each tea leaf is consistent, and reduces drying time and energy consumption. 3. By combining the flipping component and the throwing component, the tea leaves are fully turned over during the drying process, reducing the breakage of the tea leaves and avoiding damage caused by prolonged standing or uneven heating during the drying process. This solves the problem of severe tea breakage, ensures the integrity and appearance of the tea leaves, and improves the market value of the tea leaves. 4. By optimizing the combination of the feeding chamber, the flipping component, the throwing component, and the hot air guiding component, the drying efficiency is improved, energy consumption is reduced, the drying uniformity of tea is improved, and the integrity and quality of tea are guaranteed.

Detailed Implementation

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of this utility model. Furthermore, the accompanying drawings of this utility model are for simple illustrative purposes only and are not depictions of actual dimensions, as stated in advance. The following embodiments will further describe the relevant technical content of this utility model in detail, but the disclosed content is not intended to limit the scope of protection of this utility model.

[0028] Example 1: According to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, this embodiment provides a tea drying device with a rotating hot air guide plate, including a feeding chamber, a flipping component, a throwing component, and a hot air guide component 2. The feeding chamber has an inner cavity 3 and an outer cavity 4. The outer cavity 4 is disposed on the outer periphery of the inner cavity 3. The throwing component is disposed in the inner cavity 3. The flipping component is disposed outside the throwing component and adjusts the posture of the throwing component. The hot air guide component 2 is disposed in the outer cavity 4 and pumps drying hot air toward the throwing component. The material throwing component includes a placement plate 6, a conical throwing disc 14, a throwing drive motor 15, and an isolation storage net 8. The placement plate 6 is symmetrically arranged at both ends of the isolation storage net 8. The throwing drive motor 15 is driven and connected to the conical throwing disc 14 to form a throwing section. The throwing section is symmetrically arranged on the placement plate 6. The isolation storage net 8 surrounds the periphery of the placement plate 6 to form a drying chamber for placing tea leaves.

[0029] In this embodiment, the placement plate 6 is circular and is respectively disposed at both ends of the isolation storage net 8.

[0030] Optionally, the conical throwing disc 14 has radial throwing ribs on the contact side with the tea leaves, and the throwing ribs are spirally distributed along the center of symmetry of the conical throwing disc 14.

[0031] like Figure 5 As shown, the isolation storage net 8 is provided with a feed inlet, which is used for the passage of tea leaves (including feeding and discharging).

[0032] The output shaft of the throwing drive motor 15 is coaxially arranged and connected with the conical throwing disk 14. When the throwing drive motor 15 rotates, it drives the conical throwing disk 14 synchronously.

[0033] In this embodiment, when the throwing drive motor 15 starts, it drives the conical throwing disc 14 to rotate via the transmission mechanism. During rotation, the radial throwing ribs on the conical throwing disc 14 push the tea leaves, pushing them from the center of the disc to the outer edge, and throwing them up along the periphery of the disc. The conical throwing disc 14 has radial throwing ribs on the contact side with the tea leaves. These ribs are spirally distributed along the center of symmetry of the conical throwing disc 14, which can evenly throw the tea leaves upward, while also allowing the tea leaves to collide with each other during the tumbling process, increasing the friction between the tea leaves and helping to evaporate moisture more effectively.

[0034] To further enhance the turning effect of the tea leaves, the surface of the tossing ribs is provided with micro-protrusions. These protrusions increase the contact area with the tea leaves, making it easier for the tea leaves to tumble and loosen during the tossing process, thereby promoting the evaporation of moisture from the tea leaves during drying. These micro-protrusions also help prevent the tea leaves from piling up or sticking together on the tray, maintaining the free flow of the tea leaves and ensuring the uniformity of the drying effect.

[0035] As the conical feeding disc 14 rotates continuously, the tea leaves are constantly pushed up and turned over, being tossed from the inside out and from bottom to top, ensuring that the hot air can evenly contact all surfaces of the tea leaves, thereby accelerating moisture evaporation. This process not only helps with drying but also reduces uneven drying caused by excessively high local temperatures or humidity.

[0036] After the tea leaves have been turned over a certain amount, the rotation of the tossing disc will automatically adjust to adapt to different stages of tea drying. The tea leaves are repeatedly turned over and tossed throughout the drying chamber to keep them in optimal drying condition and prevent uneven drying or localized dampness caused by prolonged lack of turning.

[0037] The throwing component can not only effectively turn and toss the tea leaves, but also ensure that each tea leaf can fully contact the hot air, thereby improving the efficiency and uniformity of tea drying.

[0038] In this embodiment, the gaps in the isolation storage mesh 8 are precisely designed to ensure that the tea leaves can be fully ventilated and dried, while preventing tea leaf fragments from flying out, especially the tiny tea leaf fragments generated during the drying process. If these fragments are discharged with the hot air, they may pose safety hazards during the heating process, such as fire risks. Therefore, the size of the gaps and mesh of the isolation storage mesh 8 is limited in the following way: The mesh size of the isolation storage mesh 8 is optimized, with the mesh size being smaller than or equal to the average diameter of the tea leaves to prevent the leaves from flying out. This effectively prevents small tea leaves from entering the external environment or the hot air system, thus avoiding the risk of fire caused by the leaves coming into contact with the heating device during the heating process.

[0039] In addition, the isolation storage net 8 is made of high-temperature resistant and fire-resistant materials, such as stainless steel, high-temperature resistant plastics or metal materials coated with fire-retardant coatings, to ensure that it will not cause combustion or other safety accidents due to excessive heat in high-temperature environments.

[0040] An air filter assembly is provided in the hot air guide to further intercept tea leaf fragments that may fly out through the isolation storage net 8. The air filter assembly is located at the junction of the inner cavity 3 and the outer cavity 4 (not shown in the figure).

[0041] In this embodiment, the air filtration component can effectively filter tea fragments without affecting the flow of hot air during the tea drying process. High-temperature and corrosion-resistant materials such as stainless steel mesh, high-temperature resistant glass fiber, aluminum alloy, polyimide filter cloth or ceramic filter screen are preferred. These materials can work stably in high-temperature environments and ensure the safety and efficiency of the system.

[0042] The interaction between the feeding chamber and the throwing component allows the tea leaves to be evenly distributed in the drying chamber and to undergo initial agitation. This ensures that the entire device can be heated evenly during the tea feeding and drying process, effectively preventing the tea leaves from scorching due to accumulation or excessive concentration, and ensuring the uniformity of heating throughout the drying process.

[0043] like Figure 2 As shown, throwing sections are symmetrically arranged on the upper and lower walls of the isolation storage net 8. The throwing sections throw up the tea leaves that enter the isolation storage net 8, so that the tea leaves can come into contact with the hot air inside the casing 1 to achieve the drying effect.

[0044] Optionally, the hot air guiding component 2 is disposed on the outer layer of the isolation storage net 8 and performs a drying operation on the tea leaves stored in the drying chamber of the isolation storage net 8.

[0045] Optionally, the hot air guiding component 2 includes a multi-layer rotating guide plate 21, a guide plate driving mechanism 20, and a heater group 19. The multi-layer rotating guide plates 21 are arranged at intervals in the outer cavity 4 along the vertical direction. Each rotating guide plate is provided with a heating device on one side. The guide plate driving mechanism 20 is driven and connected to the rotating guide plate.

[0046] The airflow direction of the multi-layer rotating guide plate 21 is towards one side of the inner cavity 3, such as... Figure 2 As shown, air is blown towards one side of the isolation storage network 8.

[0047] like Figure 2 or Figure 6As shown, the support shaft on one side of the multi-layer rotating guide disk 21 is hinged to the inner wall of the housing 1, and the support shaft on the other side of the multi-layer rotating guide disk 21 is driven by the drive shaft of the guide disk drive mechanism 20. Under the drive of the guide disk drive mechanism 20, the multi-layer rotating guide disk 21 can be driven synchronously.

[0048] A reflector 22 is positioned on the side of the heater assembly 19 furthest from the multi-layer rotating guide plate 21, reflecting the heat from the heater assembly 19 back to one side of the multi-layer rotating guide plate 21. This effectively improves the thermal efficiency of the hot air guide plate and avoids heat waste. This design ensures that the heat generated by the heater assembly 19 is fully utilized and enhances the temperature uniformity of the hot air, allowing each layer of the tea leaves to receive a balanced heat supply during the drying process, thus guaranteeing high efficiency in the drying process and stability of the tea quality.

[0049] Furthermore, the reflector 22 can be made of a high-reflectivity metal or aluminum alloy to ensure maximum heat reflection efficiency. The angle and position of the reflector 22 can also be adjusted according to different drying requirements, thereby further improving the overall system's thermal efficiency and reducing energy consumption.

[0050] Through the efficient cooperation of the hot air guiding component 2 and the material throwing component, the hot air can be evenly distributed in the drying chamber, and the tea leaves can fully contact the hot air. This avoids the phenomenon of local overheating or underheating that is common in traditional drying equipment. At the same time, it improves the uniformity of drying, solves the problem of uneven heating mentioned in the background technology, ensures that the drying effect of each tea leaf is consistent, and reduces drying time and energy consumption.

[0051] Optionally, the flipping component includes a flipping track 5, a fixing seat 18, and a locking component. The fixing seat 18 is disposed on the outer wall of both ends of the isolation storage net 8 and connected to the outer wall of the placement plate 6. The fixing seat 18 is provided with a connecting protrusion 7, which is slidably connected to the flipping track 5. The locking component is disposed at the upper and lower positions of the flipping track 5 and locks the connecting protrusion 7 that enters the upper and lower positions.

[0052] Optionally, the flipping track 5 is set to be circular.

[0053] In this embodiment, the isolation storage net 8 can be rotated along the flipping track 5 by the operator's manual operation, and the upside-down posture can be reversed.

[0054] The locking component includes an electromagnetic lock and a limiting slot 9. The limiting slot 9 is set at the upper and lower positions of the flipping track 5. The electromagnetic lock controls the connecting protrusion 7 to enter or leave the limiting slot 9. When the connecting protrusion 7 enters the upper position, the electromagnetic lock is set on the connecting protrusion 7 and is set towards the side of the limiting slot 9.

[0055] The operator manually rotates the isolation storage mesh 8 along the flipping track 5. This rotation causes the tea leaves placed inside the isolation storage mesh 8 to also rotate, completing the flipping action and achieving the purpose of even heating of the tea leaves during the drying process.

[0056] When the isolation storage mesh 8 rotates to the predetermined position, the connecting protrusion 7 enters the limiting slot 9. At this time, the electromagnetic lock is activated, firmly locking the connecting protrusion 7 in the upper or lower position. The electromagnetic lock controls its locking state through current, ensuring that the tea leaves are fixed in the designated position during the tumbling process.

[0057] When the flipping direction needs to be changed, the operator moves the isolation storage mesh 8 again and presses the unlock / lock button 11 at the same time, causing the electromagnetic lock to release the connecting protrusion 7 and unlock it from the limit slot 9. At this time, the connecting protrusion 7 can slide freely to another station, enter the lower station or the upper station, and lock again under the control of the electromagnetic lock to complete the flipping in another direction.

[0058] In this embodiment, the unlock / lock button 11 is preferably located on the upper surface of the housing 1, or in a position that is convenient for the operator to operate.

[0059] The electromagnetic lock allows the operator to adjust the frequency and angle of the rotation as needed, ensuring that the tea leaves are rotated evenly throughout the drying process to achieve the best drying effect.

[0060] During the locking and unlocking process, the electromagnetic lock design ensures ease and efficiency of operation, and improves the stability and reliability of locking the isolated storage network 8.

[0061] Optionally, the isolation storage net 8 is provided with a tea inlet 12 and an electronic shut-off valve 13. The tea inlet 12 is provided with a tea channel communicating with the isolation storage net 8, and the electronic shut-off valve 13 is disposed in the tea channel.

[0062] When the isolation storage net 8 is in the forward position (i.e., the tea inlet 12 is facing upward), and the unlock / lock button 11 is pressed, the electronic shut-off valve 13 is opened, and fresh tea leaves are placed into the drying chamber through the tea inlet 12. With the help of the hot air from the hot air guide component 2, the tea leaves are dried. Conversely, once the tea leaves in the isolation storage net 8 are dry, the isolation storage net 8 is manually operated to invert it along the direction of the flipping track 5 (i.e., the tea inlet 12 is facing downwards), causing the dried tea leaves to pour out from the tea inlet 12. During the tea inlet process, the valve remains open to ensure the tea leaves smoothly enter the drying chamber; while during the pouring process, the valve automatically opens to ensure the tea leaves flow out smoothly.

[0063] In this embodiment, in the tilting position, an outlet pipe 10 and a collection drawer 16 are provided directly opposite the tea inlet 12. When the dry tea leaves are tilted out (with the electronic shut-off valve 13 in the open state), they flow out along the outlet pipe 10 and eventually fall into the collection drawer 16.

[0064] The inner wall of the outlet pipe 10 can be made of an anti-adhesion, easy-to-clean material (such as stainless steel or a coated material) to prevent tea leaves from remaining in the pipe and ensure efficient transfer of dried tea leaves. Furthermore, the pipe can be designed as a modular structure with adjustable length, facilitating adjustments to the pipe's size and orientation for different production scenarios.

[0065] The collection drawer 16 can be designed with a filter to effectively separate any remaining impurities (such as tea leaves) during the tea pouring process. Additionally, the bottom of the collection drawer 16 can be designed with an adjustable height to accommodate different drying batches and ensure complete collection of tea leaves.

[0066] like Figure 1 or Figure 2 As shown, the housing 1 has a support foot 17 on the side closest to the ground. The support foot 17 is located on one side of the housing 1 and supports the entire housing 1. In addition, the support foot 17 supports the housing 1 to form a cavity for the collection drawer 16 to be placed. At the same time, the collection drawer 16 is located below the outlet pipe 10 and receives the dried tea leaves.

[0067] By combining the flipping component and the throwing component, the tea leaves are fully turned over during the drying process, reducing breakage and preventing damage caused by prolonged sitting or uneven heating. This solves the problem of severe tea breakage, ensures the integrity and appearance of the tea leaves, and increases their market value.

[0068] Optionally, the inner cavity 3 and the outer cavity 4 are separated by a perforated plate. The main function of the perforated plate is to provide thermal insulation, reduce heat transfer between the inner cavity 3 and the outer cavity 4, thereby effectively maintaining the temperature stability of the inner cavity 3 and ensuring that the hot air energy during the tea drying process is concentrated to the maximum extent within the drying chamber, improving drying efficiency and reducing energy waste. The perforated plate also prevents the external temperature from rising, avoiding the impact of excessive temperature on equipment or electrical components, thus protecting sensitive components such as the control system and extending the service life of the equipment.

[0069] Furthermore, the pore size and material of the perforated plate can be optimized according to drying requirements to ensure smooth airflow and effective heat insulation. Its high-temperature and corrosion-resistant properties guarantee long-term stable operation in high-temperature environments. This design not only improves the efficiency of the drying system but also enhances its energy-saving effect and equipment stability.

[0070] In this embodiment, the tea drying device further includes a power supply device and a central processing unit. The power supply device is electrically connected to the throwing drive motor 15, the guide plate drive mechanism 20, the heater group 19, the electromagnetic lock, and the unlock / lock button 11 to supply power to the above-mentioned devices and maintain their normal operation.

[0071] In addition, the central processing unit is electrically connected to the material throwing drive motor 15, the guide plate drive mechanism 20, the heater group 19, the electromagnetic lock, and the unlock / lock button 11 to ensure that the entire device can operate normally.

[0072] The central processing unit and the power supply device are located inside the casing 1, preferably in a position that will not interfere with the normal operation of other devices.

[0073] In this embodiment, through the optimized combination of the feeding chamber, the flipping component, the throwing component, and the hot air guiding component 2, the drying efficiency is improved, energy consumption is reduced, the drying uniformity of tea is improved, and the integrity and quality of tea are guaranteed. This provides a new solution for the tea processing industry that is efficient, energy-saving, and protects the quality of tea.

[0074] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the protection scope of the present utility model. Therefore, all equivalent technical changes made based on the contents of the present utility model specification and drawings are included within the protection scope of the present utility model. Furthermore, the elements therein can be updated as technology develops.
