Furthermore, traditional tea drying equipment is prone to uneven heating of the tea leaves during the drying process, leading to quality differences. Additionally, high-temperature and rapid drying can cause surface moisture to evaporate too quickly, while internal moisture cannot diffuse in time, which can affect the quality of the dried tea. Therefore, improvements are needed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 5 An improved tea drying device includes a support frame 1, an inner moisture component 2 on the outer wall of the support frame 1, a controller 3, a temperature display screen 4 and an indicator light 11 fixedly installed on the outer wall of the support frame 1, a drying barrel 5 installed on the top of the support frame 1, an electric heating rod 6 fixedly mounted on the outer wall of the drying barrel 5, a top cover 7 rotatably connected to the top of the drying barrel 5, a drying auxiliary component 8 on the inner wall of the electric heating rod 6, a temperature sensor 9 fixedly embedded on the inner wall of the drying barrel 5 away from the inner moisture component 2, and a water outlet pipe 10 fixedly installed at the bottom of the drying barrel 5 near the inner moisture component 2.

[0024] In the above structure, the water outlet pipe 10 allows the water generated during the dehydration of tea leaves on the inner wall of the drying barrel 5 to flow downwards, ensuring that the tea leaves on the inner wall of the drying barrel 5 are dry and preventing the loss of nutrients. This allows the washing and dehydration of the tea leaves to be completed, maximizing the use of the device.

[0025] In a preferred embodiment: the temperature sensor 9 is electrically connected to the temperature display screen 4 and the indicator light 11; the water outlet pipe 10 is installed at an angle on the outer wall of the drying drum 5, and the lower end of the water outlet pipe 10 is located at the top of the inner humidification component 2; there are four electric heating rods 6, and the four electric heating rods 6 are evenly distributed on the outer wall of the drying drum 5; the electric heating rods 6 are electrically connected to the controller 3.

[0026] In the above structure, the controller 3 sends a signal to enable the electric heating rod 6 to start working and dry the tea leaves on the inner wall of the drying barrel 5. Since different tea leaves have different drying temperature ranges, the temperature sensor 9 monitors the temperature of the inner wall of the drying barrel 5 in real time during the drying process and displays the temperature on the surface of the temperature display screen 4 for easy observation. When the drying temperature is low, an indicator light 11 will light up. When the temperature continues to rise, the indicator light 11 will remain lit. This allows the device to dry different tea leaves, making the drying process more comprehensive.

[0027] In a preferred embodiment: the internal humidification component 2 includes a water collection tank 201, the inner wall of the water collection tank 201 is provided with a water pump 202, the outer wall of the water pump 202 is provided with a water inlet pipe 203, and the outer wall of the water inlet pipe 203 is provided with an atomizer 204.

[0028] In a preferred embodiment: the water pump 202 and the atomizer 204 are both electrically connected to the controller 3. One end of the water inlet pipe 203 is located on the inner wall of the water collection tank 201, and the other end of the water inlet pipe 203 is located on the inner wall of the drying barrel 5. The atomizer 204 is fixedly installed on the outer wall of the water collection tank 201 away from the controller 3.

[0029] In the above structure, the controller 3 sends a signal to start the water pump 202 and the atomizer 204, so that the water pump 202 can draw water from the inner wall of the water collection tank 201 to the inner wall of the water inlet pipe 203, and after being atomized by the atomizer 204, it continues to deliver cold air to the inner wall of the drying barrel 5 through the water inlet pipe 203. This allows the interior of the drying barrel 5 to undergo intermittent hot and cold treatment, thereby enhancing the toughness of the tea leaves and preventing the formation of a hard shell.

[0030] In a preferred embodiment: the drying auxiliary component 8 includes a mounting frame 801, a drive motor 802 is fixedly mounted on the outer wall of the mounting frame 801, a drive wheel 803 is fixedly mounted on the power output shaft of the drive motor 802, one end of a drive belt 804 is drivenly connected to the outer wall of the drive wheel 803, and the other end of the drive belt 804 is drivenly connected to a driven wheel 805, a rotating shaft 806 is fixedly mounted at the center of the driven wheel 805, a top plate 807 is mounted on the top of the rotating shaft 806, a spiral layer 808 is fixedly mounted on the outer wall of the rotating shaft 806, and a filter screen 809 is mounted on the bottom of the top plate 807.

[0031] In a preferred embodiment: the drive motor 802 is electrically connected to the controller 3, the mounting bracket 801 is fixedly installed on the outer wall of the support frame 1, the spiral layer 808 is spirally located on the inner wall of the filter screen 809, and the filter screen 809 is located inside the drying barrel 5.

[0032] In the above structure, by placing the tea leaves on the inner wall of the filter screen 809, the controller 3 sends a signal to start the drive motor 802, which drives the drive wheel 803 to rotate, and the transmission belt 804 drives the driven wheel 805 to rotate. As the rotating shaft 806 rotates, the moisture in the tea leaves falls through the filter screen 809 into the inner wall of the drying barrel 5. After dehydration, the tea leaves can be dried in a spiral manner while the electric heating rod 6 is started, which can effectively ensure that all sides of the tea leaves are dried evenly.

[0033] Working Principle: When using this device, remove the top cover 7 from the top of the drying barrel 5, wash the tea leaves to be dried, and place them on the inner wall of the filter screen 809. The controller 3 then sends a signal to start the drive motor 802, which in turn drives the drive wheel 803 to rotate. This causes the transmission belt 804 to drive the driven wheel 805 to rotate, allowing the rotating shaft 806 to rotate. During this rotation, the moisture in the tea leaves passes through the filter screen 809 and falls onto the inner wall of the drying barrel 5. At this point, the controller 3 sends a signal, and the electric heating rod 6 starts working, heating the inner wall of the drying barrel 5. Because different teas have different drying temperature ranges, the temperature sensor 9 monitors the temperature of the inner wall of the drying barrel 5 in real time during the drying process and displays the temperature on the surface of the temperature display screen 4. According to observation, when the drying temperature is low, an indicator light 11 will light up. When the temperature continues to rise, the indicator light 11 will continue to light up. When the temperature reaches the required drying temperature for tea, the electric heating rod 6 will stop working. During the drying process, the controller 3 sends a signal to start the water pump 202 and the atomizer 204. The water pump 202 can draw water from the inner wall of the water collection tank 201 to the inner wall of the water inlet pipe 203. After being atomized by the atomizer 204, the water continues to be delivered to the inner wall of the drying barrel 5 through the water inlet pipe 203. This allows the interior of the drying barrel 5 to undergo intermittent hot and cold treatment, thereby enhancing the toughness of the tea, preventing the formation of a hard shell, and ensuring more perfect drying of the tea, greatly improving drying efficiency and tea quality.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
