Description

Technical Field

[0001] This utility model relates to the field of black tea processing technology, and in particular to a high-efficiency black tea withering processing device. Background Technology

[0002] Black tea is a fully fermented tea and belongs to one of the six major categories of tea (green tea, white tea, yellow tea, oolong tea, and black tea). A characteristic of black tea is that its leaves undergo a relatively long period of oxidative fermentation during processing, giving the tea liquor a red or dark amber color.

[0003] The processing of black tea includes several steps such as picking, withering, rolling, fermentation, and drying. Withering is used to gradually evaporate the moisture in the tea leaves and cause the cell tissue to break down, thus laying the foundation for the subsequent rolling and fermentation processes.

[0004] Chinese patent discloses a withering device for the initial processing of black tea (authorization announcement number CN221962766U). This patented technology uses a withering box, a fan, a perforated tray, a motor, a driving roller, a driven roller, a transmission belt, and a feeding plate in cooperation. When the transmission belt rolls, the feeding plate on its outer side flips the tea leaves that fall on the perforated tray to one side. The feeding plate also moves the tea leaves around the outside of the transmission belt once before they fall back down from the top of the fan. When the fan starts, air is blown from the bottom of the perforated tray, and the contact area between the flipped tea leaves and the air increases, thereby improving processing efficiency.

[0005] However, most existing methods for withering black tea involve directly introducing air. Since the black tea accumulates on the ventilation plate during withering, this prevents proper withering and reduces its practicality. For example, the aforementioned comparative document uses a method of withering black tea on a ventilation plate. Therefore, those skilled in the art provide a high-efficiency black tea withering processing device to solve the problems mentioned in the background art. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a high-efficiency black tea withering processing device, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-efficiency black tea withering processing device, including a withering box, a heating box installed on one side of the withering box, an air outlet pipe running through the upper surface of the heating box, nozzles symmetrically arranged on the lower surface of the air outlet pipe above the withering box, and a breathable plate slidably installed inside the withering box.

[0008] Inside the withering box, a movable plate is provided above the ventilation plate. An adjustment plate slides on the lower surface of the movable plate. Rake rods are symmetrically arranged on the lower surface of the adjustment plate. Guide rods are symmetrically arranged on the rear surface of the movable plate. An electric push rod is installed on the rear surface of the withering box.

[0009] As a further technical solution of this utility model, the fixed end of the electric push rod is installed on the rear surface of the withering box, and the telescopic end of the electric push rod penetrates the interior of the withering box and is connected to the rear surface of the moving plate.

[0010] As a further technical solution of this utility model, two guide rods are symmetrically arranged on the rear surface of the moving plate, and the rear end of the guide rods penetrates the rear surface of the withering box.

[0011] As a further technical solution of this utility model, the upper surface of the adjustment plate is provided with a "T"-shaped moving block, the lower surface of the moving plate is provided with a moving groove that slides with the moving block, the inner side of the moving groove is provided with an electric telescopic rod, and the telescopic end of the electric telescopic rod is connected to one side of the moving block.

[0012] As a further technical solution of this utility model, a connecting plate is installed on the front surface of the air-permeable plate in front of the withering box, and the connecting plate is installed to the withering box by bolts.

[0013] As a further technical solution of this utility model, one side of the withering box is provided with a connection port that communicates with the moving plate, one side of the heating box is provided with an air inlet, and the other side of the withering box is provided with an exhaust hole.

[0015] This utility model provides a high-efficiency black tea withering processing device, which has the following advantages compared with the prior art:

[0016] 1. This design presents a high-efficiency black tea withering processing device. Through the arrangement of a moving plate, guide rod, electric push rod, adjusting plate, rake rod, and moving block, the electric push rod causes the moving plate to move back and forth on the ventilation plate. The rake rod disperses the black tea on the ventilation plate by rakeing it. Simultaneously, the adjusting plate can move left and right to adjust the position of the rake rod, thereby improving the dispersion of the black tea and enhancing the withering process, preventing it from piling up and affecting the withering process. It is highly practical.

[0017] 2. This design provides a high-efficiency black tea withering processing device. The permeable plate is slidably installed inside the withering box, allowing for easy installation, disassembly, and replacement. Simultaneously, an exhaust fan inside the heating box draws in and heats external air. The heated air is then sprayed upwards from the nozzle below the exhaust pipe onto the permeable plate to wither the black tea. At the same time, air also enters the withering box through the connection port and rises upwards through the ventilation holes on the permeable plate to wither the black tea, thus improving the withering effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5This utility model provides a high-efficiency black tea withering processing device: it includes a withering box 1, a heating box 2 installed on one side of the withering box 1, an air outlet pipe 21 running through the upper surface of the heating box 2, and nozzles 211 symmetrically arranged on the lower surface of the air outlet pipe 21 above the withering box 1. A permeable plate 4 is also slidably installed inside the withering box 1. The black tea that needs to be withered can be placed through the permeable plate 4, and the black tea can be heated and withered by the nozzles 211 on the lower surface of the air outlet pipe 21.

[0026] Inside the withering box 1, a movable plate 3 is installed above the ventilation plate 4. An adjustment plate 33 slides on the lower surface of the movable plate 3. A rake rod 331 is symmetrically arranged on the lower surface of the adjustment plate 33. A guide rod 31 is symmetrically arranged on the rear surface of the movable plate 3. An electric push rod 32 is installed on the rear surface of the withering box 1. The black tea on the ventilation plate 4 can be ragged by the rake rod 331 on the lower surface of the adjustment plate 33 below the movable plate 3, so as to disperse the black tea on the ventilation plate 4 and achieve its efficient withering work.

[0027] like Figure 3 and Figure 4 As shown, the fixed end of the electric push rod 32 is installed on the rear surface of the withering box 1, and the telescopic end of the electric push rod 32 penetrates the interior of the withering box 1 and is connected to the rear surface of the moving plate 3. Two guide rods 31 are symmetrically arranged on the rear surface of the moving plate 3, and the rear end of the guide rods 31 penetrates the rear surface of the withering box 1. The operation of the electric push rod 32 will cause the moving plate 3 to move back and forth inside the withering box 1. When it moves, the rake rod 331 on the lower surface of the adjusting plate 33 will rake the black tea on the ventilation plate 4 to achieve efficient withering processing.

[0028] like Figure 5 As shown, the upper surface of the adjusting plate 33 is provided with a "T"-shaped moving block 34, and the lower surface of the moving plate 3 is provided with a moving groove that slides with the moving block 34. An electric telescopic rod is provided on the inner side of the moving groove, and the telescopic end of the electric telescopic rod is connected to one side of the moving block 34. The operation of the electric telescopic rod on the inner side of the moving groove will cause the moving block 34 to move inside the moving groove. When it moves, it will adjust the position of the rake rod 331, thereby achieving the purpose of efficiently rake and disperse the black tea on the breathable plate 4.

[0029] like Figure 3 As shown, a connecting plate 41 is installed on the front surface of the ventilation plate 4 in front of the withering box 1. The connecting plate 41 is installed to the withering box 1 by bolts. The connection between the connecting plate 41 and the ventilation plate 4 allows the ventilation plate 4 to be removed for cleaning when the connecting plate 41 is disassembled.

[0030] like Figure 2 and Figure 3As shown, one side of the withering box 1 has a connection port 11 that communicates with the moving plate 3, one side of the heating box 2 has an air inlet 22, and the other side of the withering box 1 has an exhaust port. The heating box 2 is also equipped with an exhaust fan 24, and heating tubes 23 are symmetrically arranged on one side of the exhaust fan 24 inside the heating box 2. By working the exhaust fan 24 inside the heating box 2, external air can be drawn in and enter the heating box 2 to contact the heating tubes 23 for heating. The heating tubes 23 are connected to an external thermostat to control their temperature, so that the subsequent black tea withering process can be carried out.

[0031] The working principle of this utility model is as follows: When using the high-efficiency black tea withering processing device, the tea leaves to be withered are first placed on the ventilation plate 4. After placement, the exhaust fan 24 inside the heating box 2 is turned on to allow external air to enter the heating box 2 through the air inlet 22. After entering, the air is heated by the heating pipe 23. The heated air is heated and withered by the nozzle 211 on the lower surface of the air outlet 21. At the same time, another part of the hot air enters the withering box 1 through the connection port 11, so that the black tea leaves on the ventilation plate 4 are heated and withered from the bottom.

[0032] During withering, the operation of the electric push rod 32 causes the moving plate 3 to move back and forth on the ventilation plate 4. The rake rod 331 can be used to rake the black tea on the ventilation plate 4 to disperse the black tea. At the same time, the adjusting plate 33 can be moved left and right inside the moving groove by the operation of the electric telescopic rod, which can adjust the position of the rake rod 331. This can better disperse the black tea, improve the withering process, and prevent it from piling up and affecting the withering process. It is very practical.

[0033] All electrical devices used in this utility model are existing and known, and are connected to an external main controller and power supply. The main controller can be a conventional and known device such as a computer, and can be purchased and used directly on the market.
