Description

Technical Field

[0001] This utility model relates to the field of tea leaf processing technology, and in particular to a rapid withering device for tea leaves. Background Technology

[0002] Withering is one of the key processes affecting tea quality during tea processing. Traditional withering methods (such as natural spreading and sun withering) suffer from low efficiency, susceptibility to weather conditions, and unstable quality. With the large-scale and standardized development of the tea industry, rapid and controllable withering technology has become a research hotspot. Therefore, it is necessary to design a rapid withering device for fresh tea leaves.

[0003] To address this, patent CN222603646U discloses a device for withering fresh tea leaves, including a withering box. The withering box has a dryer at the top, detachable doors on both sides, and heat dissipation vents on the side walls of the dryer. A baking lamp is installed on one inner wall of the withering box, and a reflective film is installed on the opposite inner wall. The withering box also includes a tea leaf distribution device, comprising a rotating motor, a fixing frame, and a tea leaf fixing assembly. The tea leaf fixing assembly includes two sets of hinged frames, each with a fixing mesh. One set of frames has a grid, and the grid has an array of limiting cones that penetrate the fixing mesh. This invention belongs to the field of tea processing technology. Specifically, by clamping fresh tea leaves between two sets of fixing meshes and rotating the vertically positioned frames via a rotating motor, comprehensive withering is achieved, reducing manual turning. The two sets of doors facilitate cleaning of the inside of the withering box.

[0004] The aforementioned device for withering fresh tea leaves can reduce manual turning during use, but it is inconvenient to remove the withered fresh tea leaves from the fixed net during feeding, making the operation inconvenient. Therefore, it is necessary to design a rapid withering device for fresh tea leaves. Utility Model Content

[0005] The purpose of this invention is to provide a rapid withering device for fresh tea leaves, which solves the problem that existing rapid withering devices for fresh tea leaves are inconvenient to remove from the fixed mesh during feeding, resulting in inconvenient operation.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rapid withering device for fresh tea leaves, comprising a device body;

[0007] The device body has an internal flipping structure, which includes a flipping seat rotatably connected to the inner wall of the device body. The flipping seat has two rotating shafts threadedly connected to the top of each side. The top of each rotating shaft extends to the outside of the flipping seat and is fixed with a handle. The bottom of each rotating shaft is rotatably connected to a limit block. The flipping structure also includes a drive motor fixedly installed on the outer wall of the device body near the flipping seat. The flipping seat has a feeding assembly inside.

[0008] Heating boxes are fixedly installed on the inner walls of the device body on both sides of the flip seat.

[0009] Furthermore, the device body includes a wilting box, a processing chamber, a cover plate, side grooves, and side door panels. The wilting box has a processing chamber inside, and a cover plate is provided at the top of the wilting box. Side grooves are provided inside the wilting boxes on both sides of the processing chamber. Side door panels are hinged to the outer walls of the wilting boxes outside the side grooves. A dehumidification structure is provided above the heating box at the top of the processing chamber, and a turbulence structure is provided below the heating box at the bottom of the processing chamber. A temperature sensor and a humidity sensor are fixed sequentially on the inner wall of one side of the top of the wilting box.

[0010] Furthermore, the output end of the drive motor extends into the interior of the wilting box and is fixedly connected to one end of the flipping seat. The flipping seat is symmetrically distributed on both sides of the wilting box, and the limiting block is symmetrically distributed on both sides of the flipping seat.

[0011] Furthermore, the dehumidification structure includes an installation box, a desiccant pack, a reserved slot, a fan, a cover, and a suction pipe. The installation box is fixed to the inner wall of the wilting box at the top of the heating box. Each installation box contains a desiccant pack. Each installation box has a cover at its top. The reserved slot is opened inside the cover. A fan is fixedly installed at the top of the cover outside the reserved slot. The suction pipe is fixed to the outer walls on both sides of the top of the wilting box.

[0012] Furthermore, one end of the top of each suction pipe extends to the top of the processing chamber above the heating box, and one end of each suction pipe extends to the top of the processing chamber below the heating box.

[0013] Furthermore, the turbulence structure includes an air inlet pipe, an air inlet slot, and a blower. The air inlet pipe is fixed to the outer walls on both sides of the bottom of the wilting box, the air inlet slot is opened at the bottom of the wilting box, and a blower is fixedly installed at the bottom end of the wilting box outside the air inlet slot.

[0014] Furthermore, one end of the top of each air inlet pipe extends to the bottom of the processing chamber above the heating box, and one end of each air inlet slot extends to the bottom of the processing chamber below the heating box.

[0015] Furthermore, the feeding assembly includes a pressure plate, dividing rods, and a material box. The material box is located inside the tilting seat. Dividing rods are evenly fixed on the inner wall of the bottom of the material box, and a pressure plate is hinged to the top of the material box.

[0016] Furthermore, the dividing rods are evenly distributed on the inner wall of the material box, and the top of the pressure plate and the bottom of the limiting block abut against each other.

[0017] Furthermore, a first microcontroller and a second microcontroller are respectively installed inside the temperature sensor and the humidity sensor. The output terminal of the temperature sensor and the input terminal of the heating box are electrically connected through the first microcontroller, and the output terminal of the humidity sensor and the input terminal of the suction fan are electrically connected through the second microcontroller.

[0018] The advantages of the rapid withering device for fresh tea leaves provided by this utility model are as follows:

[0019] By incorporating a flipping structure and driving a motor to rotate the flipping seat, the feeding component can be evenly flipped, ensuring uniform rotation and heating of the fresh tea leaves. This avoids the problems of uneven heating or excessively high humidity caused by stacking during traditional withering processes, significantly improving withering efficiency and quality consistency. Through the coordinated operation of the limiting block, rotating shaft, and handle, the feeding component can be fixed inside the flipping seat, making the feeding component detachable and easy to remove. This not only facilitates cleaning of the feeding component but also makes it easy to quickly remove the withered fresh tea leaves. The device features the ability to quickly install and remove the feeding component from the inside of the flipping structure, improving the convenience and efficiency of the rapid withering device for fresh tea leaves.

[0020] With the dehumidification structure and the dual function of the suction fan and desiccant pack, the moisture in the processing chamber can be efficiently discharged, preventing the tea leaves from fermenting or becoming moldy due to excessive humidity. The humidity sensor is linked with the suction fan to achieve automatic humidity adjustment, ensuring a stable withering process. This device has the function of conveniently dehumidifying the inside of the processing chamber, improving the convenience and efficiency of the rapid withering device for fresh tea leaves.

[0021] By incorporating a turbulence structure, the blower delivers external air to the bottom of the processing chamber through the air inlet pipe and air inlet slot, forming an upward airflow that prevents hot air from accumulating at the top. The turbulence design reduces heat waste and, in conjunction with the heating box, enables rapid heating and shortens the withering time. This design allows the device to easily agitate the airflow inside the processing chamber, improving the efficiency of the rapid withering device for fresh tea leaves during use.

[0029] 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.

[0030] Please see Figures 1-6 This utility model provides a rapid withering device for fresh tea leaves, including a device body 1.

[0031] Reference Figures 1-6The device body 1 is internally provided with a flipping structure 2. The flipping structure 2 includes a flipping seat 22 rotatably connected to the inner wall of the device body 1. Rotating shafts 24 are threadedly connected to both sides of the top of the flipping seat 22. The top ends of the rotating shafts 24 extend to the outside of the flipping seat 22 and are fixed with handles 25. Limit blocks 23 are rotatably connected to the bottom ends of the rotating shafts 24. The flipping structure 2 also includes a drive motor 21 fixedly installed on the outer wall of the device body 1 near the flipping seat 22. The output end of the drive motor 21 extends into the interior of the withering box 11 and connects with the flipping seat 22. One end is fixedly connected, the flipping seat 22 is symmetrically distributed on both sides of the withering box 11, the limiting block 23 is symmetrically distributed on both sides of the flipping seat 22, the inner side of the flipping seat 22 is provided with a feeding assembly 6, the feeding assembly 6 includes a pressure plate 61, a dividing rod 62 and a material box 63, the material box 63 is provided on the inner side of the flipping seat 22, the dividing rod 62 is evenly fixed on the inner wall of the bottom of the material box 63, the pressure plate 61 is hinged to the top of the material box 63, the dividing rod 62 is evenly distributed on the inner wall of the material box 63, and the top of the pressure plate 61 and the bottom of the limiting block 23 abut against each other.

[0032] When the external power supply is connected and the drive motor 21 is started, the drive motor 21 can drive the rotating seat 22 to rotate, and the feeding component 6, which is evenly distributed with fresh tea leaves, slides into the inner side of the rotating seat 22. Then the rotating shaft 24 is rotated. When the rotating shaft 24 rotates, it will drive the limiting block 23 to rise or fall. When the limiting block 23 falls, it will gradually contact the top of the pressure plate 61, so as to firmly clamp the feeding component 6 inside the rotating seat 22, ensuring that the feeding component 6 can rotate with the rotating seat 22. When feeding, the fresh tea leaves are put into the material box 63. The dividing rod 62 can separate the tea leaves to prevent the fresh tea leaves from piling up together. The pressure plate 61 can limit and prevent the fresh tea leaves from falling off. The feeding component 6 rotates with the rotating seat 22 to ensure that the tea leaves are evenly exposed to the hot air.

[0033] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The device body 1 includes a withering box 11, a processing chamber 12, a cover plate 13, side grooves 14, and side door panels 15. The processing chamber 12 is located inside the withering box 11. A cover plate 13 is located at the top of the withering box 11. Side grooves 14 are located inside the withering box 11 on both sides of the processing chamber 12. Side door panels 15 are hinged to the outer walls of the withering box 11 outside the side grooves 14. A dehumidification structure 4 is located above the heating box 3 at the top of the processing chamber 12. The dehumidification structure 4 includes a mounting box 41, a desiccant pack 42, a reserved slot 43, a suction fan 44, a cover 45, and a suction pipe 46. The mounting box 41 is fixed to the inner wall of the withering box 11 at the top of the heating box 3. A desiccant pack 42 is located inside the mounting box 41. A cover 45 is located at the top of the mounting box 41. The reserved slot 43 is located inside the cover plate 13. A suction fan 44 is fixedly installed on the top of the outer cover plate 13 of the slot 43. The suction pipe 46 is fixed on the outer wall of the top two sides of the withering box 11. One end of the top of the suction pipe 46 extends to the top of the processing chamber 12 above the heating box 3, and one end of the bottom of the suction pipe 46 extends to the top of the processing chamber 12 below the heating box 3. Heating boxes 3 are fixedly installed on the inner wall of the device body 1 on both sides of the flipping seat 22. Temperature sensor 7 and humidity sensor 8 are fixedly installed on the inner wall of the top side of the withering box 11 in sequence. A first microcontroller and a second microcontroller are installed inside the temperature sensor 7 and the humidity sensor 8, respectively. The output end of the temperature sensor 7 and the input end of the heating box 3 are electrically connected through the first microcontroller. The output end of the humidity sensor 8 and the input end of the suction fan 44 are electrically connected through the second microcontroller.

[0034] With an external power supply, humid air enters the top of the processing chamber 12 through the suction pipe 46, then passes through the mounting box 41 and the desiccant pack 42, and is discharged outward through the reserved slot 43 and the suction fan 44. When the humid air passes through the desiccant pack 42, the moisture is absorbed by the desiccant pack 42. The suction fan 44 discharges dry air back into the processing chamber 12 and discharges it outward through the reserved slot 43. The reserved slot 43 and the cover 45 facilitate the replacement of the desiccant pack 42. The temperature sensor 7 uses a thermistor to sense the temperature through the change in resistance, converts the temperature change into an electrical signal, and processes and displays the value by the microcontroller. The heating box 3 is adjusted in real time to maintain the set withering temperature. The humidity sensor 8 uses a capacitive sensor to detect the humidity through the change in dielectric constant and converts the humidity data into an electrical signal. The microcontroller calculates the %RH value and controls the suction fan 44 to maintain a suitable humidity.

[0035] Reference Figure 2 , Figure 4 and Figure 5A turbulence structure 5 is provided below the heating box 3 at the bottom of the processing chamber 12. The turbulence structure 5 includes an air inlet pipe 51, an air inlet slot 52, and a blower 53. The air inlet pipe 51 is fixed to the outer walls on both sides of the bottom of the withering box 11. The air inlet slot 52 is opened at the bottom of the withering box 11. The blower 53 is fixedly installed at the bottom end of the withering box 11 outside the air inlet slot 52. One end of the top of the air inlet pipe 51 extends to the bottom of the processing chamber 12 above the heating box 3, and one end of the bottom of the air inlet slot 52 extends to the bottom of the processing chamber 12 below the heating box 3.

[0036] When the external power supply is connected and the blower 53 is started, the blower 53 sends a small amount of cold air from the outside into the processing chamber 12 through the air inlet pipe 51. The cold air flows inside the processing chamber 12, which can increase the flow speed of the hot air inside the processing chamber 12 and disturb the hot air inside the processing chamber 12 to make it evenly distributed.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
