Description

Technical Field

[0001] This utility model belongs to the field of white tea ripening technology, specifically relating to a drying device for white tea ripening. Background Technology

[0002] As a special type of tea in my country, white tea has strict requirements for drying process during its ripening. The uniformity of drying directly affects the aroma, taste and storage resistance of white tea.

[0003] Existing white tea ripening and drying equipment mostly adopts a fixed air outlet structure, with a single and concentrated airflow direction. This easily leads to uneven heating of the tea leaves in the perforated mesh basket, resulting in problems such as localized over-drying and scorching or localized under-drying and moldy areas, which seriously affects the quality of white tea. At the same time, the fixed air outlet method requires frequent manual turning of the tea leaves, which not only increases labor intensity but may also cause damage to the tea leaves due to improper manual operation, further reducing the product value. Utility Model Content

[0004] The purpose of this invention is to provide a drying device for the ripening of white tea, which can use hot air to dry the white tea during the ripening process and improve the uniformity of drying.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A drying device for ripening white tea includes a drying box, with multiple support rails fixedly connected to the inner wall of the drying box, a sealing door hinged to the side wall of the drying box, and a hollow wire mesh basket placed between two support rails located on the same horizontal line.

[0007] The bottom surface of the hollow mesh basket is fixedly connected to the connecting plates near both sides. The connecting plates abut against the support rail. Multiple guide pipes are rotatably connected between the two connecting plates. Multiple air outlets are opened on the side walls of the guide pipes. One end of the guide pipe is provided with an air supply component and a swing component.

[0008] Furthermore, the air supply assembly includes an air inlet pipe fixedly connected to the side wall of the drying chamber, the air inlet pipe extending into the interior of the drying chamber, a diverter pipe fixedly connected to the side wall of one of the connecting plates, a first connector fixedly connected to one end of the diverter pipe near the air inlet pipe, a plurality of second connectors fixedly connected to the side wall of the air inlet pipe, the first connector and the second connectors being inserted into each other, a plurality of sleeves fixedly connected to the side wall of the diverter pipe, and one end of each guide pipe being rotatably connected to a sleeve.

[0009] Furthermore, the swing assembly includes a gear fixedly connected to the side wall of the guide tube near the end face, the gear meshing with the same rack on its lower side, the rack passing through the connecting plate and movably connected to one end away from the sealing door, a drive assembly being provided in the inner cavity of the drying oven away from the sealing door, and an elastic assembly being provided at the other end of the rack.

[0010] Furthermore, the drive assembly includes a motor fixedly mounted on the top surface of the drying chamber, the output shaft of the motor being fixedly connected to a transmission shaft, the transmission shaft extending into the interior of the drying chamber, and a plurality of cams fixedly connected to the side wall of the transmission shaft, with one end of the rack abutting against the cams.

[0011] Furthermore, a roller is rotatably connected to one end of the rack, and the roller abuts against the cam.

[0012] Furthermore, the elastic component includes a fixed plate fixedly connected to the other end of the rack, a limiting rod fixedly connected to the side wall of the connecting plate, the limiting rod passing through the fixed plate and movably connected thereto, and a spring sleeved on the side wall of the limiting rod.

[0013] Furthermore, a baffle is rotatably connected to the side wall of the support track, and bolts are threadedly connected to the side wall of the baffle.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This utility model discloses a drying device for white tea ripening. Through the cooperation of a hollow mesh basket, guide pipes, air supply components, and an oscillating component, a cam drives a rack to move back and forth. The rack meshes with a gear, which drives multiple guide pipes to oscillate synchronously. This allows the airflow from the air outlet to fully cover the tea leaves in the hollow mesh basket, avoiding dead air zones. This solves the problem of uneven drying of tea leaves caused by traditional fixed air outlets, ensuring the consistency of white tea quality after ripening. Furthermore, the oscillating of the guide pipes creates a dynamic airflow, which can replace manual turning of the tea leaves. This reduces the labor intensity of operators and avoids damage and broken leaves caused by manual contact, effectively improving the yield of white tea. Attached Figure Description

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figures 1-7 As shown, a drying device for ripening white tea includes a drying box 1. Multiple support rails 2 are fixedly connected to the inner wall of the drying box 1. A sealing door 3 is hinged to the side wall of the drying box 1. A hollow mesh basket 4 is placed between two support rails 2 located on the same horizontal line. The internal structure and control principle of the drying box 1 are existing mature technologies and will not be described in detail in this solution.

[0027] The bottom surface of the perforated mesh basket 4 is fixedly connected to connecting plates 5 near both sides. The connecting plates 5 abut against the supporting rails 2. Multiple guide pipes 6 are rotatably connected between the two connecting plates 5. Multiple air outlets 7 are opened on the side walls of the guide pipes 6. An air supply component and a swing component are provided at one end of the guide pipe 6. One connecting plate 5 has a shell structure to facilitate the protection of the air supply component and the swing component, while the other connecting plate 5 has a straight plate structure to facilitate the support of the guide pipes 6.

[0028] like Figure 1 , Figure 6 and Figure 7 As shown, the air supply assembly includes an air inlet pipe 8 fixedly connected to the side wall of the drying chamber 1. The air inlet pipe 8 extends into the interior of the drying chamber 1. A diversion pipe 10 is fixedly connected to the side wall of a connecting plate 5. A first connector 11 is fixedly connected to one end of the diversion pipe 10 near the air inlet pipe 8. Multiple second connectors 9 are fixedly connected to the side wall of the air inlet pipe 8. The first connector 11 and the second connectors 9 are inserted into each other. Multiple sleeves 12 are fixedly connected to the side wall of the diversion pipe 10. One end of each guide pipe 6 is rotatably connected to a sleeve 12.

[0029] There are two ways to allow hot air to enter the air inlet pipe 8: one is to directly connect the air inlet pipe 8 to the hot air flow channel inside the drying oven 1, and the other is to allow it to enter the external heat source airflow. Users can choose according to their actual needs. This part is not the focus of this solution and will not be described in detail here.

[0030] In addition, the drying oven 1 has ventilation holes, a temperature controller and other structures, which are all conventional structures.

[0031] It should be noted that the outer diameter of the first connector 11 is smaller than the inner diameter of the second connector 9. When the hollow mesh basket 4 is pushed into the drying oven 1, the first connector 11 can be directly inserted into the second connector 9 and sealed by the sealing ring.

[0032] like Figure 1 and Figure 6 As shown, the swing assembly includes a gear 13 fixedly connected to the side wall of the guide pipe 6 near the end face. The gear 13 is meshed with the same rack 14 on its lower side. The rack 14 passes through the connecting plate 5 and is movably connected to one end away from the sealing door 3. A drive assembly is provided in the inner cavity of the drying oven 1 away from the sealing door 3. An elastic assembly is provided at the other end of the rack 14.

[0033] like Figure 7 As shown, the drive assembly includes a motor 18 fixedly mounted on the top surface of the drying chamber 1. The output shaft of the motor 18 is fixedly connected to a transmission shaft 19, which extends into the interior of the drying chamber 1. Multiple cams 20 are fixedly connected to the side wall of the transmission shaft 19, and one end of the rack 14 abuts against the cam 20.

[0034] The reciprocating linkage structure formed by the swing component and the drive component facilitates the continuous forward and reverse rotation of the guide tube 6, thereby realizing the swing of the air outlet 7. When hot air is blown out, the hot air is distributed in a fan-shaped expansion pattern, which improves its drying efficiency.

[0035] like Figure 7 As shown, a roller 21 is rotatably connected to one end of the rack 14, and the roller 21 abuts against the cam 20. The roller 21 can reduce the friction between the rack 14 and the cam 20, resulting in better transmission performance.

[0036] like Figure 6 As shown, the elastic component includes a fixed plate 15 fixedly connected to the other end of the rack 14, and a limiting rod 16 fixedly connected to the side wall of the connecting plate 5. The limiting rod 16 passes through the fixed plate 15 and is movably connected to it. A spring 17 is sleeved on the side wall of the limiting rod 16. The force of the spring 17 can apply a pushing force to the rack 14, so that the roller 21 can always be in contact with the surface of the cam 20, and the limiting rod 16 can also play a supporting role.

[0037] like Figure 5As shown, a baffle 22 is rotatably connected to the side wall of the support rail 2, and a bolt 23 is threadedly connected to the side wall of the baffle 22. This allows for the application of thrust to the perforated mesh basket 4, which facilitates increased sealing between the first joint 11 and the second joint 9, while also preventing the perforated mesh basket 4 from shifting.

[0038] The working principle of this utility model is as follows: First, the white tea is evenly spread on the hollow mesh basket 4, then the hollow mesh basket 4 is inserted into the support rail 2, and the hollow mesh basket 4 is pushed into the drying box 1 so that the first connector 11 is inserted into the second connector 9. At the same time, the roller 21 abuts against the cam 20. Then, the baffle 22 is rotated so that the baffle 22 fits against the connecting plate 5, and the bolt 23 is tightened to apply pressure to the connecting plate 5 to ensure the sealing of the connection between the first connector 11 and the second connector 9.

[0039] After all the perforated mesh baskets 4 have been pushed in, close the sealing door 3, connect the external hot air pipe to the air inlet pipe 8, and the airflow enters the diversion pipe 10 through the air inlet pipe 8, then enters the guide pipe 6 through the sleeve 12 in sequence, and blows out from the air outlet 7 to dry the white tea in the perforated mesh baskets 4 above with hot air.

[0040] At the same time, the motor 18 is started. The motor 18 drives the cam 20 to rotate through the transmission shaft 19. The cam 20 pushes the rack 14 to reciprocate. The rack 14 is always in contact with the cam 20 by the force of the spring 17. The rack 14 meshes with the gear 13 to drive the guide pipe 6 to continuously rotate in both directions, so that the airflow blown out of the air outlet 7 is in an oscillating blowing state, which increases the drying uniformity and reduces the drying dead zone.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
