Description

Technical Field

[0001] This utility model relates to the field of tea drying technology, specifically a drying box for dandelion black tea production. Background Technology

[0002] Black tea is a fully fermented tea, made from suitable new tea buds and leaves through a series of processes including withering, rolling, fermentation, and drying. During the processing of black tea, a chemical reaction centered on the enzymatic oxidation of tea polyphenols occurs, resulting in significant changes in the composition of the fresh leaves, with tea polyphenols decreasing by more than 90%. In the production of black tea, it is necessary to dry the tea leaves to reduce their moisture content, which requires specialized drying equipment for auxiliary drying treatment.

[0003] Authorization announcement number CN112841337A discloses a tea drying device, including a drying base, with support plates fixedly connected to both ends of the top of the drying base, a rotating seat fixedly connected to the top of the support plates, a drying barrel rotatably connected to one side of the rotating seat, a gear ring passing through and fixedly connected to one end of the drying barrel, a drive motor fixedly connected to the top of the drying base, a drive gear fixedly connected to the drive shaft of the drive motor, the top of the drive gear meshing with the bottom of the gear ring, a feed pipe connected to one side of the drying barrel, a hot air pipe fixedly connected to one side of the inner wall of the drying barrel, a diversion air pipe connected to the side of the hot air pipe, and a discharge device provided on the side of the drying barrel.

[0004] The drying drum of the current device is placed horizontally. When unloading, the tea leaves are evenly scattered at the bottom of the drying drum, making it impossible to quickly gather the tea leaves inside the drying drum. This results in a slow unloading process. To address this, we propose a drying box for dandelion black tea production. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a drying box for dandelion black tea production. The tea leaves inside the round box are turned over to ensure that the tea leaves are heated evenly. The box is placed at an angle to facilitate the expulsion of hot air and moisture, and the tea leaves inside are discharged quickly, saving time and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drying box for dandelion black tea production, comprising a base plate, with three circular boxes evenly spaced on the upper side of the base plate. The left and right ends of the three circular boxes are respectively fixedly connected to discs. An air inlet pipe is connected to the upper part of the left surface of the left disc, and an exhaust screen is opened on the right surface of the right disc. The left and right discs are respectively fixedly connected to connecting plates via fixing blocks. The front and rear parts of the left fixing block are movably connected to the upper ends of support rods via bearings. The lower ends of the two support rods are respectively fixedly connected to corresponding positions on the upper surface of the base plate. The front and rear parts of the right fixing block are respectively connected to the upper ends of hydraulic rods via bearings. The lower ends of the two hydraulic rods are also movably connected to corresponding positions on the upper surface of the base plate via bearings. The input end of the hydraulic rod is electrically connected to the output end of an external power supply via an external control switch group.

[0007] The design features an adjustable tilt angle for the circular chamber, allowing for quick emptying of the tea leaves and increasing the output speed. The adjustable angle also provides an upward-sloping air passage for the expulsion of hot air and moisture. When operating the drying chamber, an external control switch extends the hydraulic rod, raising the right side of the chamber. Tea leaves are then placed inside, and hot air is blown into the chamber through the air inlet to dry the leaves. Hot air and moisture are expelled through the exhaust screen. After drying, the hydraulic rod retracts, tilting the right side of the chamber downwards for easy emptying of the tea leaves.

[0008] Furthermore, the drying box also includes motors. The left side surface of the connecting plate on the left side and the center position of the disc are respectively fixedly connected to the motors. The output shafts of the three motors extend into the interior of the circular box through the circular holes opened on the connecting plate and the disc, and are respectively fixedly connected to the left end. Stirring blades are fixedly connected to each rotating rod at equal angles.

[0009] The design incorporates a stirring blade, which rotates to agitate the tea leaves, ensuring even heating and increasing drying efficiency. An external control switch controls the motor, which in turn rotates the rotating rod, which in turn rotates the stirring blade, thus agitating the tea leaves.

[0010] Furthermore, the drying chamber also includes inlet and outlet ports, with inlet and outlet ports respectively located on the right side surface of the right-side disc and on the lower side of the exhaust screen.

[0011] Tea leaves are fed into the round box through the inlet and outlet.

[0012] Furthermore, the drying box also includes a collection box and a chute. The chute is provided on the upper right side of the bottom plate. The lower end of the chute is fixedly connected to the front and rear parts of the front and rear parts, respectively. The two slide bars are slidably connected to the chute opened at the corresponding position on the upper surface of the bottom plate.

[0013] The design incorporates a collection box to receive the dried tea leaves, and a chute facilitates the disassembly of the collection box.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This drying oven for dandelion black tea production has the following advantages:

[0015] 1. The design incorporates a circular box with an adjustable tilt angle, allowing for quick emptying of the tea leaves inside by adjusting the tilt angle, thereby increasing the tea discharge speed.

[0024] Please see Figure 1-4This embodiment provides a technical solution: a drying box for dandelion black tea production, including a base plate 1, with three circular boxes 2 evenly spaced on the upper side of the base plate 1. The left and right ends of the three circular boxes 2 are respectively fixedly connected to discs 3. An air inlet pipe 4 is connected to the upper part of the left surface of the left disc 3, and an exhaust screen 8 is opened on the right surface of the right disc 3. The left and right discs 3 are respectively fixedly connected to connecting plates 9 via fixing blocks 7. The front and rear parts of the left fixing block 7 are respectively movably connected to the upper ends of support rods 5 via bearings. The lower ends of the two support rods 5 are respectively fixedly connected to corresponding positions on the upper surface of the base plate 1. The front and rear parts of the right fixing block 7 are respectively connected to the upper ends of hydraulic rods 6 via bearings. The lower ends of the two hydraulic rods 6 are also movably connected to corresponding positions on the upper surface of the base plate 1 via bearings. The input end of the hydraulic rod 6 is electrically connected to the output end of an external power supply via an external control switch group.

[0025] The design incorporates a circular box 2 with an adjustable tilt angle. By adjusting the tilt angle of the circular box 2, the tea leaves inside can be quickly poured out, thereby increasing the tea discharge speed. Simultaneously, adjusting the angle provides an upward-sloping air passage for the expulsion of hot air and moisture. When controlling the drying chamber, the hydraulic rod 6 is first extended via an external control switch, raising the right end of the circular box 2. Tea leaves are then placed inside the circular box 2, and hot air is blown into the interior through the air inlet pipe 4 to dry the tea leaves. Hot air and moisture are expelled through the exhaust screen 8. After drying, the hydraulic rod 6 is retracted, causing the right end of the circular box 2 to tilt downwards, facilitating the pouring of the tea leaves.

[0026] The drying oven also includes a motor 10. The left side surface of the connecting plate 9 on the left side and the center position of the disc 3 are respectively fixedly connected to the motor 10.

Each rotating rod 11 is fixedly connected to the stirring blade 12 at an equal angle.

[0027] The agitator 12 is designed to turn the tea leaves over, thereby ensuring even heating and increasing the efficiency of the drying process. The motor 10 is controlled by an external control switch group, which in turn drives the rotating rod 11 to rotate, which in turn drives the agitator 12 to rotate, thus turning the tea leaves over.

[0028] The drying chamber also includes inlet and outlet ports. Inlet and outlet ports are respectively opened on the right side surface of the disc 3 on the right side and on the lower side of the exhaust screen 8.

[0029] Tea leaves are fed into the cylindrical box 2 through the inlet and outlet.

[0030] The drying oven also includes a collection box 13 and a chute 14. The chute 14 is provided on the upper right side of the base plate 1. The front and rear parts of the lower end of the chute 14 are respectively fixedly connected to slide bars. The two slide bars are slidably connected to the chute 14 opened at the corresponding position on the upper surface of the base plate 1.

[0031] The collection box 13 is designed to receive the dried tea leaves, and the slide 14 is designed to facilitate the disassembly of the collection box 13.

[0032] The working principle of the drying box for dandelion black tea production provided by this utility model is as follows:

[0033] The hydraulic rod 6 is extended by an external control switch group, thereby raising the right end of the cylindrical box 2. Tea leaves are then placed into the cylindrical box 2 through the inlet and outlet. Hot air is then blown into the cylindrical box 2 through the air inlet pipe 4 to dry the tea leaves. At the same time, the motor 10 is controlled by the external control switch group to drive the rotating rod 11 to rotate, which in turn drives the stirring blade 12 to rotate, thereby turning the tea leaves. Hot air and moisture are discharged through the exhaust net 8. After drying, the hydraulic rod 6 is retracted, thereby tilting the right end of the cylindrical box 2 downward, which facilitates the pouring of the tea leaves. The poured tea leaves fall into the collection box 13.

[0034] It is worth noting that the hydraulic rod 6 disclosed in the above embodiments is a Longxiang hydraulic rod, and the operation of the hydraulic rod 6 and the motor 10 is controlled by an external control switch group using a method commonly used in the prior art.
