Description

Technical Field

[0001] This application relates to the technical field of tea processing equipment, specifically to an electromagnetic heating tea-frying drum temperature equalization device. Background Technology

[0002] Tea frying is one of the key steps in tea processing. Traditional tea frying equipment mostly uses gas or electric heating tubes, which has problems such as inaccurate temperature control, high energy consumption, and environmental pollution. In recent years, electromagnetic heating technology has been gradually applied to tea frying equipment due to its advantages such as high efficiency, energy saving, and environmental protection. However, electromagnetic heating tea frying drums still face the problem of uneven temperature distribution in practical applications, resulting in uneven heating of tea leaves and affecting tea quality. At present, there is little research in the industry on temperature equalization technology for electromagnetic heating tea frying drums, and there is an urgent need for a technical solution that can effectively solve the problem of uneven temperature distribution.

[0003] In the above-mentioned method of uniformly heating and frying tea leaves, multiple sets of single electromagnetic coils can be arranged in sections, with a temperature sensor installed in each section. Subsequently, the controller automatically adjusts the heating power and time of the multiple sets of electromagnetic coils based on the feedback information from the temperature sensors to achieve precise temperature control and uniformity. The inner wall of the drum is lined with heat-conducting material, and with the continuous stirring of the stirring rod, the tea leaves can be thoroughly fried, greatly enhancing the function of uniform heating. However, since the freshly fried tea leaves are very hot, too much steam will appear when the door is opened to take them out, which can easily cause harm to personnel. If a cooling function is added, the harm to personnel will be greatly reduced. To solve the above problems, an electromagnetic heating tea frying drum temperature equalization device is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an electromagnetic heating tea-frying drum temperature equalization device, which has the advantages of uniform heating during tea frying and steam reduction, thus solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: an electromagnetic heating tea-frying drum temperature equalization device, comprising two support plates, a drum rotation mechanism, a cylindrical drum, a uniform distribution mechanism, and a cooling mechanism. The uniform distribution mechanism includes five electromagnetic coils fixedly installed on the surface of the cylindrical drum. Five temperature sensors are fixedly installed inside the cylindrical drum. A heat-spreading plate is fixedly connected inside the cylindrical drum. A second bearing is fixedly connected to the inner wall side of the cylindrical drum. A support shaft is rotatably connected inside the second bearing. Several stirring rods are fixedly connected to the surface of the support shaft. A fixed cylinder is fixedly connected to one end of the support shaft. The fixed cylinder passes through the cylindrical drum and is fixedly connected to the side of a support plate. A fixed box is fixedly connected to the side of one of the support plates. A controller is fixedly installed inside the fixed box.

[0006] The above solution utilizes a rotating drum mechanism driven by a stable motor, ensuring continuous and consistent power and uniform rotation of the cylindrical drum. The stirring rod, accompanying the drum's rotation, continuously agitates the tea leaves, ensuring full contact between the tea leaves and the drum wall. This promotes heat conduction and prevents uneven heating. A uniform distribution mechanism, equipped with five electromagnetic coils, generates a uniform magnetic field through distributed heating, effectively preventing localized overheating of the drum surface. Five temperature sensors provide real-time and accurate temperature monitoring at different locations within the drum, offering detailed data for temperature control. A heat spreader rapidly dissipates heat, further reducing temperature gradients and achieving uniform heat distribution within the drum. Simultaneously, the controller intelligently adjusts the electromagnetic coil power and time based on sensor feedback, achieving precise temperature control and balanced adjustment. The coordinated operation of these mechanisms, through intelligent control and efficient cooperation, comprehensively enhances temperature uniformity, ensuring the quality of tea processing. A cooling mechanism effectively removes steam emanating from the drum, increasing personnel safety.

[0007] Furthermore, the roller rotation mechanism includes a first drive motor fixedly mounted on the side of a support plate via a mounting plate, a first bearing fixedly connected to the side of the support plate, a first rotating shaft rotatably connected inside the first bearing, one end of the first rotating shaft being fixedly connected to the output shaft of the first drive motor, and a cylindrical roller fixedly connected to the other end of the first rotating shaft.

[0008] The above scheme provides a driving force to the drum rotation mechanism by setting a first drive motor, a rotational force to the cylindrical drum by setting a first bearing and a first rotating shaft, and a storage area for tea leaves by setting a cylindrical drum.

[0009] Furthermore, the cooling mechanism includes eight horizontal plates fixedly connected to the side of a support plate. Two air boxes are fixedly connected to the sides of the eight horizontal plates. A second drive motor is fixedly installed on the side of one of the support plates. A third bearing is fixedly connected to the side of each of the two air boxes. A second shaft is rotatably connected inside each of the two third bearings. One end of one of the second shafts is fixedly connected to the output shaft of the second drive motor. Pulleys are fixedly connected to the surfaces of both second shafts. A transmission belt drives between the two pulleys. Several fan blades are fixedly connected to the surfaces of both second shafts. A mesh cover is provided inside each of the two air boxes.

[0010] The above scheme provides support for the bellows by setting a horizontal plate, provides a mounting location for the cooling devices by setting the bellows, provides rotational power for the fan blades by setting a third bearing and a second rotating shaft, allows two types of fans to operate using a single drive mechanism by setting a pulley and a transmission belt, removes steam by setting the fan blades, and covers the inside of the bellows by setting a mesh cover.

[0011] Furthermore, exhaust pipes are fixedly connected to both sides of the cylindrical roller, and filter plates are fixedly connected inside both exhaust pipes.

[0012] The above solution allows for the removal of steam from the cylindrical drum by installing an exhaust pipe, and for the filtration of external dust by installing a filter plate.

[0013] Furthermore, a window or door is movably connected to the surface of the cylindrical roller via a hinge, and the window or door is made of ferrous material.

[0014] The above solution, by setting up windows and doors, can achieve the effect of sealing the inside of the cylindrical roller.

[0015] Furthermore, the cylindrical roller is provided with four magnetic blocks inside.

[0016] The above method, by setting up magnetic blocks, can effectively lock windows and doors.

[0017] Furthermore, each of the two support plates is fixedly connected to a support leg at its bottom, and there are four support legs, with a rubber block fixedly connected to the bottom of each of the four support legs.

[0018] The above solution provides support for the entire device by setting up support legs, and provides anti-slip properties by setting up rubber blocks.

[0019] Furthermore, a baffle is movably connected to the side of the fixing box via a hinge, and a fixing block is fixedly connected to both the bottom of the fixing box and the side of the baffle. Limiting rods are inserted into the interior of the two fixing blocks, and several heat dissipation holes are provided on the side of the fixing box.

[0020] The above solution protects the controller by setting a baffle frame, locks the baffle frame by setting a fixing block and a limit rod, and allows the heat generated by the controller to be discharged by setting heat dissipation holes.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This electromagnetic heating tea-frying drum temperature equalization device features a rotating drum mechanism driven by a stable motor, ensuring continuous and consistent power to maintain the uniform rotation of the cylindrical drum.

[0036] In this embodiment, the electromagnetic heating tea-frying drum temperature equalization device utilizes a drum rotation mechanism 2 driven by a stable motor. This ensures continuous and stable power, guaranteeing uniform rotation of the cylindrical drum 204. The stirring rod 306 continuously agitates the tea leaves as the drum 204 rotates, ensuring full contact between the tea leaves and the drum wall. This promotes heat conduction and prevents uneven heating. Furthermore, the uniform distribution mechanism 3, equipped with five electromagnetic coils 301, generates a uniform magnetic field through distributed heating, effectively preventing localized overheating of the drum 204 surface. Five temperature sensors 302 are also included. The temperature at different locations within the cylindrical drum 204 is precisely monitored, providing detailed data support for temperature control.

All mechanisms work together, and through intelligent control and efficient coordination, the temperature balance effect is comprehensively improved, ensuring the quality of tea frying. By setting up the cooling mechanism 4, the steam emitted from the cylindrical drum 204 can be removed, increasing personnel safety.

[0037] The working principle of the above embodiment is as follows: First, tea leaves are introduced into the cylindrical drum 204. Then, the window 7 is closed and locked using the magnetism of the magnetic block 14. Next, the electromagnetic coil 301 operates to heat the tea leaves, and the heating plate 303 rapidly heats the cylindrical drum 204. Then, the first drive motor 201 operates, driving the first rotating shaft 203 to rotate, causing the tea leaves in the cylindrical drum 204 to rotate and be heated. During rotation, the stirring rod 306 agitates the tea leaves to ensure even heating. During heating, the temperature sensor 302 operates to transmit the temperature data of each area to the control unit. Inside the control unit 309, the operator can remove the limit rod 12 and open the baffle 10. Then, the operator can adjust the heating degree of each electromagnetic coil 301 according to the transmitted temperature data to achieve a uniform temperature. During the tea frying process, the hot air inside the cylindrical drum 204 can be discharged through the exhaust pipe 5. After the tea is fried, the second drive motor 403 operates to drive a second shaft 405 and a pulley 406 to rotate. With the transmission characteristics of the transmission belt 407, another second shaft 405 is driven to rotate, thereby causing the fan blades 408 to blow air onto the window 7. Finally, the window 7 is opened to reduce the amount of steam.
