Description

Technical Field

[0001] This utility model relates to the field of tea fixation technology, and in particular to a device for controlling the uniformity of temperature during tea drum fixation. Background Technology

[0002] Drum fixation is a crucial step in tea processing, primarily used in the initial processing of green tea, yellow tea, and other tea varieties. It rapidly deactivates oxidases in fresh leaves at high temperatures, inhibiting the oxidation of polyphenols and preserving the tea's color and quality. Traditional fixation methods include pan-frying and steaming, while drum fixation machines utilize the rotation and heating of metal drums to ensure even heating of fresh leaves, offering high efficiency and controllability.

[0003] In the prior art, such as Chinese Patent No. CN206851933U, there is a heating device and a drum-type tea-processing machine, belonging to the field of tea processing equipment. The drum-type tea-processing machine includes a heating device and a drive mechanism. The heating device includes a frame, a heat-insulating shell, a drum, and a temperature control device. The temperature control device includes a cooling element, a heating element, a temperature sensor, and a temperature control element. The temperature control element adjusts the heating temperature of the heating element based on the temperature feedback from the temperature sensor, and works in conjunction with the cooling element to achieve a constant heating temperature. The drive mechanism drives the drum to rotate, ensuring uniform heating of the tea leaves. The drum-type tea-processing machine ensures uniform heating and a constant temperature of the tea leaves during the tea-processing process, to a certain extent avoiding the phenomena of scorched edges, cracked spots, and inconsistent color caused by uneven heating, thereby improving the quality of the tea.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: although it can ensure a constant temperature of tea leaves during the heating and fixing process through the cooperation of heating elements, temperature sensors, cooling elements and temperature control elements, the tea leaves are divided into high-temperature zone, medium-temperature zone and low-temperature zone during the fixing process. The multiple heating elements are evenly arranged on the outer surface of the drum, which makes the temperature of the drum inlet section, middle section and outlet section the same, which may result in a lower quality of tea leaves during fixing. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that, although the temperature of tea leaves can be kept constant during the heating and fixing process through the cooperation of heating elements, temperature sensors, cooling elements and temperature control elements, the tea leaves are divided into high temperature zone, medium temperature zone and low temperature zone during the fixing process. The multiple heating elements are arranged at equal intervals on the outer surface of the drum, so that the temperature of the drum inlet section, middle section and outlet section is the same, which may result in the lower quality of tea leaf fixing.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a tea drum with uniform temperature control device, comprising: an outer shell, wherein a drum body is rotatably connected to the inner wall of the outer shell, and further comprising:

[0007] Multiple connecting pipes 1 are fixedly connected in a circumferential array to the outer surface of the outer shell. Multiple connecting pipes 2 are fixedly connected in a circumferential array to the outer surface of the outer shell. The interior of the outer shell is provided with a high-temperature tank, a medium-temperature tank, and a low-temperature tank. Multiple mounting plates 1 are fixedly connected in a circumferential array to opposite sides of the inner wall of the high-temperature tank. Multiple heating wires 1 are fixedly connected at equal intervals to the inner walls of the multiple mounting plates 1. Multiple mounting plates 2 are fixedly connected in a circumferential array to opposite sides of the inner wall of the medium-temperature tank. Multiple heating wires 2 are fixedly connected at equal intervals to the inner walls of the mounting plates 2. A solenoid valve 1 is fixedly connected to the inner wall of the connecting pipe 1 near the high-temperature tank. A solenoid valve 2 is fixedly connected to the inner wall of the connecting pipe 2 near the inner wall of the medium-temperature tank.

[0008] Preferably, the high-temperature tank, the plurality of connecting pipes one and the low-temperature tank are connected together, and the medium-temperature tank, the plurality of connecting pipes two and the low-temperature tank are connected together.

[0009] Preferably, the inner wall of the roller body is fixedly connected with multiple guide vanes, and the inner wall of the roller body is fixedly connected with multiple temperature sensors at equal intervals. The roller body is provided with a feed inlet and a discharge outlet.

[0010] Preferably, a base plate is provided at the bottom of the outer shell, and two support plates are symmetrically fixedly connected to the top of the base plate, both of which are fixedly connected to the outer shell.

[0011] Preferably, a motor is fixedly connected to one side of one of the support plates, a second gear is fixedly connected to the output shaft of the motor, and a first gear is fixedly connected to the outer surface of the roller body, with the first gear meshing with the second gear.

[0012] Preferably, two fixing plates are symmetrically fixedly connected to one side of the other support plate, and a guide frame is rotatably connected to the opposite side of the two fixing plates via a support rod.

[0013] Preferably, a second U-shaped block is fixedly connected to the top of the base plate, and an electric telescopic rod is rotatably connected to the opposite side of the two arms of the second U-shaped block via a support rod. A first U-shaped block is fixedly connected to the bottom of the guide frame, and the electric telescopic rod is rotatably connected to the first U-shaped block via a support rod.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. This utility model uses a controller to control heating wire one and heating wire two for heating. The number of heating wire one inside the high-temperature tank is greater than that inside the medium-temperature tank, resulting in a faster temperature rise in the high-temperature tank, which is higher than the temperature inside the medium-temperature tank. This allows the interior of the drum body to be divided into high-temperature, medium-temperature, and low-temperature zones from the inlet to the outlet. Temperature sensors detect and control the temperature of different zones within a suitable range. When the temperature in the low-temperature zone is low, the controller opens solenoid valve one and solenoid valve two, allowing hot air from the high-temperature and medium-temperature tanks to flow into the low-temperature tank, thus controlling the temperature of the low-temperature zone. Conversely, when the temperature is high, solenoid valves one and two are closed. This allows the tea leaves to undergo high-temperature, medium-temperature, and low-temperature treatments during the withering process inside the drum body, thereby improving the quality of the withering process.

[0016] 2. This utility model uses a controller to activate the electric telescopic rod, causing it to extend or retract. This applies a force to the first U-shaped block, pushing or pulling the guide frame upwards or downwards, causing it to rotate at an appropriate angle. This adjusts the tilt angle of the guide frame. Simultaneously, both ends of the electric telescopic rod rotate around the first and second U-shaped blocks at appropriate angles via support rods. This allows for proper adjustment of the tilt angle of the guide frame, controlling the speed at which tea leaves fall into the guide frame and preventing tea leaves from accumulating and damaging them.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Examples, such as Figure 1-4 As shown, this utility model provides a tea drum with uniform temperature control device, including: an outer shell 1, with a drum body 2 rotatably connected to the inner wall of the outer shell 1, and further including: multiple connecting pipes 101 arranged in a circumferential array and fixedly connected to the outer surface of the outer shell 1; multiple connecting pipes 102 arranged in a circumferential array and fixedly connected to the outer surface of the outer shell 1; the interior of the outer shell 1 is provided with a high-temperature tank 105, a medium-temperature tank 106 and a low-temperature tank 107; multiple mounting plates 108 are arranged in a circumferential array and fixedly connected to the opposite side of the inner wall of the high-temperature tank 105; multiple heating wires 109 are equidistantly fixedly connected to the inner walls of the multiple mounting plates 108; multiple mounting plates 110 are arranged in a circumferential array and fixedly connected to the opposite side of the inner wall of the medium-temperature tank 106; multiple heating wires 111 are equidistantly fixedly connected to the inner walls of the mounting plates 110; a solenoid valve 1 is fixedly connected to the inner wall of the connecting pipe 101 near the inner wall of the high-temperature tank 105; and a solenoid valve 2 is fixedly connected to the inner wall of the connecting pipe 102 near the inner wall of the medium-temperature tank 106.

[0026] Furthermore, such as Figure 1-4As shown, the high-temperature bath 105, multiple connecting pipes 101, and the low-temperature bath 107 are connected together. The medium-temperature bath 106, multiple connecting pipes 102, and the low-temperature bath 107 are connected together. Through the connection pipes 101, the hot air inside the high-temperature bath 105 can enter the low-temperature bath 107 through the connection pipes 101. Through the connection pipes 102, the hot air inside the medium-temperature bath 106 can enter the low-temperature bath 107 through the connection pipes 102.

[0027] Furthermore, such as Figure 1-4 As shown, multiple guide vanes 204 are fixedly connected to the inner wall of the drum body 2, and multiple temperature sensors 205 are fixedly connected at equal intervals to the inner wall of the drum body 2. The drum body 2 is provided with a feed inlet and a discharge outlet. The guide vanes 204 facilitate the stirring of tea leaves, increase the time the tea leaves stay inside the drum body 2, and keep the time from the feed inlet to the discharge outlet appropriate.

[0028] Furthermore, such as Figure 1-4 As shown, a base plate 104 is provided below the outer shell 1. Two support plates 103 are symmetrically fixedly connected to the top of the base plate 104. Both support plates 103 are fixedly connected to the outer shell 1. Through the above arrangement, they serve to support the outer shell 1.

[0029] Furthermore, such as Figure 1-4 As shown, a motor 203 is fixedly connected to one side of one of the support plates 103. A gear 202 is fixedly connected to the output shaft of the motor 203. A gear 201 is fixedly connected to the outer surface of the roller body 2. The gear 201 meshes with the gear 202. The motor 203 is started by the controller, so that its output shaft drives the gear 202 to rotate. Then, with the meshing of the gear 202 and the gear 201, the roller body 2 can be driven to rotate.

[0030] Furthermore, such as Figure 1-4 As shown, two fixed plates 3 are symmetrically fixed to one side of another support plate 103. The opposite sides of the two fixed plates 3 are rotatably connected to the guide frame 301 through the support rod. With the above arrangement, the guide frame 301 can be rotated at an appropriate angle, thereby controlling the tilt angle of the guide frame 301.

[0031] Furthermore, such as Figure 1-4As shown, a second U-shaped block 304 is fixedly connected to the top of the base plate 104. An electric telescopic rod 303 is rotatably connected to one side of the two arms of the second U-shaped block 304 via a support rod. A first U-shaped block 302 is fixedly connected to the bottom of the guide frame 301. The electric telescopic rod 303 is rotatably connected to the first U-shaped block 302 via a support rod. With the above arrangement, when the electric telescopic rod 303 extends or retracts, it can rotate around the second U-shaped block 304 and the first U-shaped block 302 by an appropriate angle via the support rod.

[0032] Working Principle: During operation, tea leaves are fed into the drum body 2 through the inlet. The drum body 2 has a certain inclination, with the inlet slightly higher than the outlet. The controller then starts the motor 203, causing its output shaft to drive gear 202. Gear 202 meshes with gear 1, rotating the drum body 2. With the assistance of the guide plate 204, the tea leaves are evenly stirred and conveyed towards the outlet. Simultaneously, the controller controls heating wires 109 and 111 to heat the tea. The high-temperature tank 105 has more heating wires 109 than the medium-temperature tank 106, resulting in a faster temperature rise in the high-temperature tank 105, exceeding the temperature in the medium-temperature tank 106. This creates a temperature distribution within the drum body 2, from the inlet to the outlet, of high-temperature, medium-temperature, and low-temperature zones. Temperature sensor 205 monitors the temperature in different zones and maintains it within a suitable range. When the low-temperature zone is too low, the controller can adjust the temperature accordingly. The controller opens solenoid valves one and two, allowing hot air from the high-temperature tank 105 and medium-temperature tank 106 to flow into the low-temperature tank 107, thus controlling the temperature of the low-temperature zone. Conversely, it closes solenoid valves one and two. This allows the tea leaves to undergo high-temperature, medium-temperature, and low-temperature treatments during the fixing process inside the drum body 2, thereby improving the quality of the fixing. After fixing, the tea leaves are discharged from the outlet onto the guide frame 301. The controller then activates the electric telescopic rod 303, causing it to extend or retract. Applying a force to U-shaped block 302 can push or pull the guide frame 301 upwards or downwards, causing it to rotate at an appropriate angle. This adjusts the tilt angle of the guide frame 301. Simultaneously, the two ends of the electric telescopic rod 303 rotate at an appropriate angle around U-shaped block 302 and U-shaped block 304 via support rods. This allows for proper adjustment of the tilt angle of the guide frame 301, controlling the speed at which tea leaves fall into the guide frame 301 and preventing tea leaves from accumulating and damaging them.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
