Description

Technical Field

[0001] This invention relates to the field of tea drying technology, and in particular to a method for determining tea drying parameters of a tea drying device, the tea drying device and its control method. Background Technology

[0002] Tea is a common daily beverage. Tea lovers usually keep a variety of teas at home to meet their drinking needs at different times and in different situations. However, the home storage environment is easily affected by factors such as season and weather, and the temperature and humidity fluctuate greatly. Tea has a strong hygroscopic property and is very easy to absorb moisture from the air during storage, which will cause the tea to darken in color, lose its aroma, and deteriorate in taste, directly affecting the drinking experience after brewing. Therefore, it is necessary to dry the damp tea.

[0003] Existing tea drying equipment usually requires manual setting of parameters such as drying temperature and drying time. However, since the drying temperature and drying time are mostly selected based on personal habits or experience, it is difficult to guarantee the quality of the dried tea. Over-drying or under-drying of the tea can easily occur, which will still affect the taste of the tea after brewing.

[0004] Therefore, there is an urgent need for a method for determining the tea drying parameters of a tea drying device, as well as a tea drying device and its control method, to solve the above problems. Summary of the Invention

[0005] Based on the above problems, the purpose of this invention is to provide a method for determining the tea drying parameters of a tea dryer, a tea dryer and its control method, which can achieve precise determination of the tea drying parameters, improve the quality consistency and stability of the tea dried by the tea dryer, and ensure the taste of the dried tea.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Firstly, a method for determining the tea drying parameters of a tea roaster is provided, including the following steps: S1. Take multiple samples of damp tea leaves to be dried; S2. A set of drying parameters is set for each sample of damp tea leaves, and each set of drying parameters is different; the drying parameters include at least drying temperature and drying time. S3. Place each sample of damp tea leaves into a tea drying apparatus and set the corresponding drying parameters on the tea drying apparatus to dry the damp tea leaves and obtain the dried tea leaves. S4. Brew the damp tea samples and each group of dried tea samples, and record the quality parameters of each group of brewed tea samples. The quality parameters include at least the shape of the tea leaves, the color of the soup, the aroma, the taste, and the tea leaves after brewing. S5. Compare and analyze the quality parameters of multiple tea samples to obtain the target drying parameters for the damp tea samples. S6. Store the target drying parameters in the control system of the tea dryer.

[0007] As an optional solution to the method for determining the tea drying parameters of the tea roaster of the present invention, in step S2: The drying temperature ranges from 80℃ to 110℃, with a difference of 5℃ to 15℃ between each group of drying temperatures; and / or, the drying time ranges from 10min to 30min, with a difference of 5min to 15min between each group of drying times.

[0008] As an optional embodiment of the method for determining tea drying parameters for the tea drying apparatus of the present invention, the plurality of drying parameters include: Drying temperature: 80℃, drying time: 20min; Drying temperature: 80℃, drying time: 30min; Drying temperature: 90℃, drying time: 10min; Drying temperature: 90℃, drying time: 20min; Drying temperature: 90℃, drying time: 30min; Drying temperature: 100℃, drying time: 10min; Drying temperature: 100℃, drying time: 20min; Drying temperature: 100℃, drying time: 30min; Drying temperature: 110℃, drying time: 20min.

[0009] As an optional embodiment of the method for determining the tea drying parameters of the tea dryer of the present invention, the tea dryer includes a drying fan and a tea basket rotatably disposed inside the tea dryer. The drying fan is used to introduce a drying airflow into the tea dryer, and the tea basket is used to hold the tea leaves. In step S2, the drying parameters also include the wind speed of the drying fan and / or the rotation speed of the tea basket.

[0010] As an optional solution to the method for determining the tea drying parameters of the tea drying device of the present invention, the wind speed of the drying fan is in the range of 500rpm to 1000rpm, and the difference between each group of wind speeds is 50rpm to 100rpm. And / or, the rotation speed of the tea basket is in the range of 2 rpm to 8 rpm, and the difference between each set of rotation speeds is 1 rpm to 2 rpm.

[0011] As an optional solution to the method for determining the tea drying parameters of the tea dryer of the present invention, in step S4, the same brewing conditions are used when brewing the tea sample, and the brewing conditions include brewing water temperature, brewing water volume and brewing time. And / or, step S5 includes: scoring each of the quality parameters to obtain a score value for each of the quality parameters; calculating a comprehensive score value for the quality parameters of each tea sample based on the score value of each of the quality parameters and the corresponding preset percentage weight; and determining the target drying parameters for the damp tea sample based on the comprehensive score value of the quality parameters.

[0012] Secondly, a tea roaster control method is provided, wherein the tea roaster has multiple tea roasting modes, each tea roasting mode corresponding to a type of tea; the target drying parameters for each tea roasting mode are determined using the tea drying parameter determination method for the tea roaster described above. The tea roaster control method includes the following steps: Receive user input operation instructions, including a tea roasting mode; When the received operation instruction is the tea roasting mode, determine whether the current tea roasting mode has been confirmed; If so, the tea dryer is controlled to operate according to the target drying parameters corresponding to the tea drying mode.

[0013] As an optional embodiment of the tea roaster control method of the present invention, before determining whether the current tea roasting mode is confirmed, the following steps are also included: Determine whether the drying parameters in the current tea roasting mode have been adjusted; If so, after the current tea-drying mode is confirmed, the tea-drying device will be controlled to operate according to the adjusted drying parameters.

[0014] As an optional embodiment of the tea roaster control method of the present invention, the tea roaster has a teaware drying mode, and the operation command includes the teaware drying mode; the tea roaster control method further includes the following steps: When the received operation command is the teaware drying mode, the tea dryer is controlled to operate according to the drying parameters corresponding to the teaware drying mode.

[0015] Thirdly, a tea drying device is provided, which is controlled by the tea drying device control method described above. The tea drying device includes a box, a tea basket and a drying fan. The tea basket is rotatably disposed in the box and is used to hold tea leaves to be dried. The drying fan is used to introduce drying airflow into the box.

[0016] The beneficial effects of this invention are as follows: The method for determining tea drying parameters for a tea dryer provided by this invention involves first setting multiple sets of drying parameters to dry damp tea samples separately, then brewing the dried tea samples, and using the quality parameters of the brewed tea samples as evaluation indicators to determine the target drying parameters for the damp tea samples. Finally, the target drying parameters are stored in the control system of the tea dryer, so that the tea dryer operates according to the determined target drying parameters when drying the same type of tea in subsequent cycles. By determining the target drying parameters for tea using this method, the drying temperature, drying time, and other drying parameters of the tea can be kept appropriate, ensuring the drying effect while preserving the aroma and taste of the tea to the greatest extent, thus improving the quality of the tea. Furthermore, setting the target drying parameters on the tea dryer ensures the consistency and stability of the quality of the tea in each subsequent drying cycle, improves the automation level of the tea dryer, reduces the difficulty of operation for users, enhances the convenience of using the tea dryer, and improves the user experience.

[0017] The tea drying device control method and tea drying device provided by this invention allow the user to select a drying mode on the tea drying device according to the type of tea to be dried, such as by button selection or touch screen selection. After selecting and confirming the current drying mode, the control system of the tea drying device receives the corresponding control command, and then controls the tea drying device to operate at the target drying parameters (drying temperature, drying time, etc.) corresponding to the current drying mode to dry the tea. Since the target drying parameters corresponding to the current drying mode are the optimal drying parameters for this type of tea, the drying effect and the taste of the tea after brewing can be guaranteed.

[0018] Because the tea basket is rotatably mounted inside the drying chamber, it can be kept rotating during the drying process, allowing the drying airflow generated by the drying fan to come into more thorough contact with the tea leaves inside the basket, thus improving the uniformity of heating and the drying efficiency of the tea leaves.

[0022] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0025] Example 1 This embodiment provides a method for determining the tea drying parameters of a tea roaster, which can achieve precise determination of the tea drying parameters, improve the consistency and stability of the quality of tea dried by the tea roaster, and ensure the taste of the tea after drying.

[0026] like Figure 1 As shown, the method for determining the tea drying parameters of a tea roaster includes the following steps: S1. Take multiple samples of damp tea leaves to be dried; S2. Set a set of drying parameters for each sample of damp tea leaves. Each set of drying parameters is different. The drying parameters should include at least the drying temperature and the drying time. S3. Place each sample of damp tea leaves into a tea drying apparatus and set the corresponding drying parameters on the tea drying apparatus to dry the damp tea leaves and obtain the dried tea leaves. S4. Brew the damp tea samples and each group of dried tea samples, and record the quality parameters of each group of brewed tea samples. The quality parameters should include at least the shape of the tea leaves, the color of the soup, the aroma, the taste, and the tea leaves after brewing. S5. Compare and analyze the quality parameters of multiple groups of tea samples to obtain the target drying parameters for damp tea samples; among them, the tea samples dried using the target drying parameters have the best quality parameters after brewing. S6. Store the target drying parameters in the control system of the tea dryer.

[0027] The method for determining tea drying parameters for a tea dryer provided in this embodiment involves first setting multiple sets of drying parameters to dry damp tea samples separately, then brewing the dried tea samples, and using the quality parameters of the brewed tea samples as evaluation indicators to determine the target drying parameters for the damp tea samples. Finally, the target drying parameters are stored in the control system of the tea dryer so that the tea dryer can operate according to the determined target drying parameters when drying the same type of tea in subsequent applications.

[0028] Determining the target drying parameters for tea using this method ensures that the drying temperature, time, and other parameters are appropriate during the tea drying process. This guarantees effective drying while maximizing the preservation of the tea's aroma and flavor, thus improving overall quality. Furthermore, setting the target drying parameters on the tea dryer ensures consistency and stability in the quality of subsequent drying processes. It also enhances the automation level of the tea dryer, reduces operational complexity, improves ease of use, and enhances the user experience.

[0029] Optionally, in step S2, the drying temperature ranges from 80℃ to 110℃, with a temperature difference of 5℃ to 15℃ between each group of drying temperatures. Limiting the drying temperature to the range of 80℃ to 110℃ avoids excessively low temperatures, ensuring drying efficiency, while also preventing excessively high temperatures from scorching or burning the tea leaves, thus ensuring the quality of the dried tea.

[0030] Optionally, in step S2, the drying time ranges from 10 min to 30 min, and the difference between each set of drying times is 5 min to 15 min. Limiting the drying time to the range of 10 min to 30 min ensures sufficient time for drying the tea leaves, while avoiding excessive drying time that could cause the tea leaves to become over-dried and lose their aroma, and also reasonably reduces the drying waiting time.

[0031] Optionally, in step S4, the same brewing conditions are used when brewing the tea samples. These conditions include the brewing water temperature, the amount of water, and the brewing time. Using the same brewing conditions to brew the dried tea samples eliminates the influence of brewing conditions on tea quality, thereby accurately and objectively reflecting the impact of drying parameters on tea quality. This ensures that the final target drying parameters are accurate and reliable, and consequently ensures that the tea obtained when subsequently dried using a tea drying machine maintains good and stable quality.

[0032] In other embodiments, brewing conditions may also include the amount of tea, the teaware used, etc.

[0033] Optionally, step S5 includes: S51. Score each quality parameter to obtain the score value of each quality parameter. S52. Calculate the comprehensive quality parameter score for each tea sample based on the score values ​​of each quality parameter and the corresponding preset percentage weights. S53. Determine the target drying parameters for the damp tea samples based on the comprehensive score of the quality parameters.

[0034] By quantifying and scoring various quality parameters (tea shape, liquor color, aroma, taste, and infused leaf appearance, etc.) and using percentage weighting to calculate a comprehensive score, standardized evaluation of tea quality can be achieved. This eliminates the influence of human subjectivity on quality parameters, making tea quality evaluation more objective and repeatable. Furthermore, the aforementioned comparative analysis method for tea quality can reasonably reflect the contribution of each quality parameter to the overall quality of the tea, thus providing a more comprehensive and accurate reflection of the tea's overall quality, making the tea quality evaluation more valuable and persuasive.

[0035] Optionally, the preset percentage weights for each quality parameter are as follows: tea appearance 20%, liquor color 5%, aroma 30%, taste 35%, and infused leaf 10%.

[0036] In other embodiments, the preset percentage weights of each quality parameter can also be adaptively adjusted according to actual needs, and are not limited to the specific percentage values ​​listed above.

[0037] In this embodiment, the drying temperature is set in 10°C increments, and the drying time is set in 10-minute increments. The multiple sets of drying parameters specifically include: (1) Drying temperature: 80℃, drying time: 20min; (2) Drying temperature: 80℃, drying time: 30min; (3) Drying temperature: 90℃, drying time: 10min; (4) Drying temperature: 90℃, drying time: 20min; (5) Drying temperature: 90℃, drying time: 30min; (6) Drying temperature: 100℃, drying time: 10min; (7) Drying temperature: 100℃, drying time: 20min; (8) Drying temperature: 100℃, drying time: 30min; (9) Drying temperature: 110℃, drying time: 20min.

[0038] Following the nine sets of drying parameters mentioned above, each sample of damp tea was placed in a tea drying apparatus, and the corresponding drying parameters were set on the apparatus to dry the tea samples. Then, each of the nine dried tea samples was brewed, and the quality parameters of each sample were recorded.

[0039] Taking Tieguanyin tea as an example, nine samples of damp tea leaves were dried, and the dried tea leaves were then brewed. The resulting quality parameter data are shown in Table 1 below. The preset percentage weights for each quality parameter are as follows: tea appearance 20%, liquor color 5%, aroma 30%, taste 35%, and infused leaf 10%.

[0040] Table 1: In the table above, the first row of data represents the results obtained after brewing raw tea samples that have not undergone drying treatment.

[0041] The data in the table above shows that when the drying temperature is 90℃ and the drying time is 30min, the comprehensive quality parameter score of Tieguanyin tea is the highest. Therefore, the target drying parameters for Tieguanyin tea can be determined as follows: drying temperature 90℃ and drying time 30min.

[0042] Taking Da Hong Pao tea as an example, nine samples of damp tea were dried, and the dried tea samples were then brewed. The resulting quality parameter data are shown in Table 2 below. The preset percentage weights for each quality parameter are as follows: tea appearance 20%, liquor color 5%, aroma 30%, taste 35%, and infused leaf 10%.

[0043] Table 2: The data in the table above shows that the Da Hong Pao tea has the highest comprehensive quality parameter score when the drying temperature is 110℃ and the drying time is 20min. Therefore, the target drying parameters for Da Hong Pao tea can be determined as follows: drying temperature 110℃ and drying time 20min.

[0044] Taking Ya Shi Xiang Dan Cong tea as an example, nine samples of damp tea leaves were dried, and the dried tea leaves were then brewed. The resulting quality parameter data are shown in Table 3 below. The preset percentage weights for each quality parameter are as follows: tea appearance 20%, liquor color 5%, aroma 30%, taste 35%, and infused leaf 10%.

[0045] Table 3: The data in the table above shows that the highest comprehensive quality score of Ya Shi Xiang Dan Cong tea is achieved when the drying temperature is 110℃ and the drying time is 20 minutes. Therefore, the target drying parameters for Ya Shi Xiang Dan Cong tea can be set as follows: drying temperature 110℃ and drying time 20 minutes.

[0046] Taking West Lake Longjing tea as an example, nine samples of damp tea leaves were dried, and the dried tea leaves were then brewed. The resulting quality parameter data are shown in Table 4 below. The preset percentage weights for each quality parameter are as follows: tea appearance 20%, liquor color 5%, aroma 30%, taste 35%, and infused leaf 10%.

[0047] Table 4: The data in the table above shows that West Lake Longjing tea has the highest comprehensive quality parameter score when the drying temperature is 80℃ and the drying time is 20min. Therefore, the target drying parameters for West Lake Longjing tea can be determined as follows: drying temperature 80℃ and drying time 20min.

[0048] Taking Jin Jun Mei tea as an example, nine samples of damp tea were dried, and the dried tea samples were then brewed. The resulting quality parameter data are shown in Table 5 below. The preset percentage weights for each quality parameter are as follows: tea appearance 20%, liquor color 5%, aroma 30%, taste 35%, and infused leaf 10%.

[0049] Table 5: The data in the table above shows that when the drying temperature is 100℃ and the drying time is 20 minutes, the comprehensive quality parameter score of Jin Jun Mei tea is the highest. Therefore, the target drying parameters for Jin Jun Mei tea can be determined as follows: drying temperature 100℃ and drying time 20 minutes.

[0050] In other embodiments, the drying temperature can be set in increments of 5°C, 8°C, 12°C, 15°C, etc., but is not limited to the specific values ​​listed above. The drying time can also be set in increments of 5 min, 6 min, 7 min, 9 min, 12 min, 15 min, etc., but is not limited to the specific values ​​listed above.

[0051] Example 2 This embodiment provides a method for determining the tea drying parameters of a tea drying device, which is a further improvement on the first embodiment.

[0052] See Figure 2 and Figure 3 The tea drying apparatus includes a drying fan 30 and a tea basket 20 rotatably disposed within the apparatus. The drying fan 30 is used to introduce drying airflow into the apparatus, and the tea basket 20 is used to hold the tea leaves. The tea basket 20 has multiple ventilation holes on its outer periphery. When using the tea drying apparatus to dry tea leaves, the user can place damp tea leaves into the tea basket 20 and then place the tea basket 20 into the apparatus. The apparatus is then activated, causing the drying fan 30 to operate and simultaneously rotating the tea basket 20. The drying airflow blows onto the rotating tea basket 20 and enters the basket 20 through the ventilation holes, allowing the airflow to contact the tea leaves and dry them. Because the tea basket 20 is constantly rotating during the drying process, the drying airflow can enter the tea basket 20 from any ventilation hole on the outer periphery of the tea basket 20. This allows the tea leaves in any position inside the tea basket 20 to fully contact the drying airflow, thereby improving the heat uniformity of the tea leaves, enhancing the drying uniformity and efficiency, and ensuring the drying effect and the brewing taste of the dried tea leaves.

[0053] In step S2, the drying parameters also include the wind speed of the drying fan 30 and / or the rotation speed of the tea basket 20.

[0054] In this embodiment, when setting the drying parameters in step S2, each group of drying parameters includes two additional parameters: the wind speed of the drying fan 30 and the rotation speed of the tea basket 20. When drying each sample of damp tea, the corresponding group of wind speed and rotation speed parameters are set on the tea dryer. By comparing and analyzing the quality parameters of multiple dried tea samples, the target drying parameters for the damp tea samples are obtained. These target drying parameters include drying temperature, drying time, the wind speed of the drying fan 30, and the rotation speed of the tea basket 20.

[0055] The target drying parameters for tea are determined by this method and stored in the tea dryer. This ensures that the drying temperature and time are appropriate when the tea is dried using the dryer, and that the wind speed of the drying fan 30 and the rotation speed of the tea basket 20 are also appropriate. This ensures both the drying efficiency and uniformity of the tea, as well as its quality, preventing damage to its aroma and flavor, and maintaining the best taste after brewing.

[0056] Of course, in some embodiments, in step S2, the drying parameters may simply be increased by increasing the wind speed of the drying fan 30 or the rotation speed of the tea basket 20.

[0057] Optionally, in step S2, the wind speed of the drying fan 30 is in the range of 500 rpm to 1000 rpm, and the difference between each set of wind speeds is 50 rpm to 100 rpm. Limiting the wind speed of the drying fan 30 to the range of 500 rpm to 1000 rpm ensures that the drying fan 30 has sufficient air output efficiency to provide a stable drying airflow for the tea in the tea basket 20, thus ensuring drying efficiency.

[0058] Optionally, in step S2, the rotational speed of the tea basket 20 ranges from 2 rpm to 8 rpm, with a difference of 1 rpm to 2 rpm between each set of speeds. Limiting the rotational speed of the tea basket 20 to the range of 2 rpm to 8 rpm ensures the rotation of the tea basket 20 while preventing it from rotating too fast, thus preventing the tea basket 20 from moving or tipping over arbitrarily.

[0059] In this embodiment, the same method as in Embodiment 1 can be used. Multiple sets of drying parameters are taken, and each sample of damp tea is placed in a tea drying apparatus. The corresponding drying parameters are set on the tea drying apparatus to dry the damp tea samples. Then, the multiple dried tea samples are brewed, and the quality parameters of each tea sample are recorded. By scoring the quality parameters of the tea samples, the optimal target drying parameters are obtained.

[0060] For example, taking Tieguanyin tea as an example, the optimal drying parameters obtained through actual experimental testing are: drying temperature 90℃, drying time 30min, drying fan speed 800rpm, and tea basket rotation speed 3rpm.

[0061] For other types of tea, the above steps can be repeated to obtain the corresponding drying parameters.

[0062] Optionally, see Figure 2 , Figure 4 and Figure 5 The tea drying device also includes a tray 50 and a rotary drive 60. The output end of the rotary drive 60 is connected to the tray 50 and can drive the tray 50 to rotate, with the tea basket 20 placed on the tray 50. During the drying process, the rotary drive 60 drives the tray 50 to rotate, thereby causing the tea basket 20 on the tray 50 to be in a rotating state.

[0063] In addition, since the tea basket 20 is placed directly on the tray 50, users can directly take the tea basket 20 off and put it on the tray 50 when using the tea dryer, without having to fix or disassemble the tea basket 20. This simplifies the tea drying process and improves the user experience.

[0064] Optionally, see Figure 4 The bottom of the tea basket 20 is equipped with multiple ventilation holes and a support structure. When the tea basket 20 is placed on the tray 50, a gap is maintained between the bottom of the tea basket 20 and the tray 50. This design allows the drying airflow to pass through the gap between the bottom of the tea basket 20 and the tray 50 during the tea drying process. Furthermore, the drying airflow can enter the tea basket 20 through the multiple ventilation holes at the bottom, further improving the uniformity of heat distribution to the tea leaves and enhancing the drying efficiency and effect.

[0065] Example 3 This embodiment provides a tea drying device control method. The tea drying device has multiple tea drying modes, each corresponding to a type of tea. The target drying parameters for each tea drying mode are determined using the tea drying parameter determination method for the tea drying device described above. By setting multiple tea drying modes on the tea drying device, users can directly select the corresponding tea drying mode when drying the corresponding type of tea, simplifying the operation process and ensuring the quality of the dried tea.

[0066] like Figure 6 As shown, the tea roaster control method includes the following steps: R1 receives user input operation commands, including tea roasting mode; R2. When the received operation command is tea roasting mode, determine whether the current tea roasting mode has been confirmed. If so, the tea dryer will be controlled to operate according to the target drying parameters corresponding to the tea drying mode; If not, the tea roaster will not be used for the time being.

[0067] The tea dryer control method provided in this embodiment allows the user to select a drying mode on the tea dryer according to the type of tea to be dried, such as by pressing buttons or using a touchscreen. After selecting and confirming the current drying mode, the control system of the tea dryer receives the corresponding control command and then controls the tea dryer to operate at the target drying parameters (drying temperature, drying time, etc.) corresponding to the current drying mode to dry the tea. Since the target drying parameters corresponding to the current drying mode are the optimal drying parameters for that type of tea, the drying effect and the taste of the tea after brewing are guaranteed.

[0068] For example, the drying parameter determination method described in Embodiment 1 or Embodiment 2 can be used to conduct experimental tests on teas such as Tieguanyin, Da Hong Pao, Ya Shi Xiang Dan Cong, West Lake Longjing, and Jin Jun Mei, and obtain the corresponding target drying parameters. A tea drying mode corresponding to each of the tea types (Tieguanyin, Da Hong Pao, Ya Shi Xiang Dan Cong, West Lake Longjing, and Jin Jun Mei) is set on the tea drying device. Then, the determined target drying parameters are stored in multiple tea drying modes of the tea drying device control system. When the user selects a tea drying mode corresponding to a certain tea type, the control system operates according to the target drying parameters corresponding to the tea drying mode to dry the tea.

[0069] Optionally, a confirmation button can be set on the tea dryer. After selecting the tea drying mode, pressing the confirmation button will allow the control system to receive the confirmation of the current tea drying mode and then control the tea dryer to operate according to the set target drying parameters.

[0070] Optionally, the tea drying apparatus includes a drying fan and a heating module. The drying fan is used to introduce drying airflow into the tea drying apparatus, and the heating module is used to heat the airflow generated by the drying fan. In step R2, the drying temperature is adjusted by controlling the operating parameters of the heating module, and the drying time is adjusted by controlling the operating duration of the drying fan and the heating module. Furthermore, the operating speed of the drying fan and the rotation speed of the tea basket can be controlled according to the target drying parameters.

[0071] Optionally, such as Figure 7 As shown, before determining whether the current tea roasting mode is confirmed, the following steps are also included: R3. Determine whether the drying parameters in the current tea roasting mode have been adjusted; If so, after the current tea drying mode is confirmed, the tea dryer will be controlled to operate according to the adjusted drying parameters.

[0072] That is, after the user selects the current tea drying mode, the current tea drying mode is not immediately confirmed. Instead, the drying parameters are adjusted. At this time, after the current tea drying mode is confirmed, the tea dryer will operate with the drying parameters adjusted by the user, which can meet the user's needs for customizing the drying of tea leaves and improve the flexibility of using the tea dryer.

[0073] Optionally, temperature and time adjustment buttons can be set on the tea dryer. After selecting the corresponding tea drying mode, the user can further adjust the corresponding drying temperature and drying time through the temperature and time buttons. After the drying temperature and drying time are determined, the control system will control the operation of the tea dryer according to the adjusted drying temperature and drying time.

[0074] Optionally, the tea roaster has a teaware drying mode, and the operation instructions include the teaware drying mode. The tea roaster control method also includes the following steps: R4. When the received operation command is the teaware drying mode, control the operation of the tea dryer according to the drying parameters corresponding to the teaware drying mode.

[0075] When a user needs to dry their teaware, they place the teaware inside the tea dryer, select the teaware drying mode, and once the drying mode is confirmed, the control system operates the tea dryer according to the corresponding drying parameters to dry the teaware. In other words, this tea dryer can also meet the needs of drying and sterilizing teaware, making its functions more diverse and further enhancing the user experience.

[0076] Example 4 like Figure 2 and Figure 3 As shown, this embodiment provides a tea drying device, which is controlled by the tea drying device control method described above. The tea drying device includes a box 10, a tea basket 20 and a drying fan 30. The tea basket 20 is rotatably disposed in the box 10 and is used to hold the tea leaves to be dried. The drying fan 30 is used to introduce drying airflow into the box 10.

[0077] The tea drying device provided in this embodiment allows the tea basket 20 to be rotatably installed inside the housing 10. Therefore, the tea basket 20 can be kept rotating during the drying process, so that the drying airflow generated by the drying fan 30 can come into more full contact with the tea leaves in the tea basket 20, thereby improving the heat uniformity and drying efficiency of the tea leaves and ensuring the drying effect and the brewing taste of the dried tea leaves.

[0078] See Figure 2 and Figure 3 The tea dryer also includes a drying fan 30 and a heating module 40. The drying fan 30 is used to introduce drying airflow into the tea dryer, and the heating module 40 is used to heat the airflow generated by the drying fan 30. The hot airflow blows towards the rotating tea basket 20 inside the housing 10 and enters the tea basket 20 through multiple ventilation holes on the outer periphery and bottom of the tea basket 20, so that the hot airflow comes into contact with the tea leaves in the tea basket 20 to dry the tea leaves and improve the heat uniformity of the tea leaves.

[0079] See Figure 4 and Figure 5The tea drying device also includes a rotary drive unit 60 and a support tray 50. A support plate 70 is provided at the output end of the rotary drive unit 60. The support tray 50 and the support plate 70 are detachably connected. A tea basket 20 is placed on the support tray 50. During the drying process, the rotary drive unit 60 drives the support plate 70 to rotate the support tray 50 and the tea basket 20, ensuring that the tea basket 20 is always rotating and that the tea leaves inside are heated evenly. Because the support tray 50 and the support plate 70 are detachably connected, the support tray 50 can be removed separately later for easy cleaning, such as removing tea leaves from the support tray 50, reducing the difficulty of cleaning and maintenance.

[0080] Optionally, the tray 50 is provided with a first engaging structure, and the support plate 70 is provided with a second engaging structure. The first engaging structure engages with the second engaging structure to limit the relative position of the tray 50 and the support plate 70, so that the tray 50 can rotate synchronously with the support plate 70. The tray 50 is fixed by engaging, making the loading and unloading of the tray 50 more convenient.

[0081] For example, the first engaging structure may be an engaging protrusion, and the second engaging structure may be an engaging groove 701 (e.g., Figure 5 As shown in the figure, both the engaging protrusion and the engaging groove 701 have non-circular cross-sections. After the engaging protrusion engages with the engaging groove 701, it can circumferentially limit the bearing tray 50 and the support plate 70, so that the bearing tray 50 cannot rotate relative to the support plate 70, ensuring that the bearing tray 50 can rotate stably.

[0082] See Figure 2 The box body 10 is equipped with a door, and the door 101 is openable and closable. During the tea drying process, the door 101 is closed to ensure the drying is airtight. When taking out or putting in the tea basket 20, the door 101 can be opened to place the tea basket 20 on the tray 50 or to take the tea basket 20 out of the tray 50.

[0083] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
