[0025] The withering tube 2 is connected to the inner wall of the outer tube 1. A stirring mechanism is arranged inside the withering tube 2 for stirring the tea leaves and scraping off the tea leaves adhering to the inner wall of the withering tube 2. The inner wall of the withering tube 2 is made of heat-insulating material. The outermost side of the withering tube 2 is in the shape of a truncated cone, with a smaller side facing outward and provided with a circular hole connected to the interior of the withering tube 2. Materials can be fed into the withering tube 2 through the circular hole. The angle of the end of the truncated cone is adjusted downward so that the circular hole faces the ground. At this time, the inner wall arranged in a slope can facilitate the tea leaves to slide out of the withering tube 2. When withering, the stirring mechanism The tea leaves in the withering cylinder 2 are stirred to make the tea leaves evenly and fully heated, thereby increasing the withering rate of the tea leaves. The stirring mechanism can scrape off the tea leaves adsorbed on the inner wall of the withering cylinder 2, so that the tea leaves will not be adsorbed on the inner wall of the withering cylinder 2 for a long time, which is convenient for discharging the tea leaves and improving the quality of the tea leaves after withering. The heating chamber 12 is connected to the outer cylinder 1, and a heating mechanism for conveying hot air into the withering cylinder 2 is provided on the heating chamber 12. By introducing hot air into the withering cylinder 2, the internal temperature of the withering cylinder 2 is increased, thereby withering the tea leaves inside the withering cylinder 2.

[0026] There are two rotating blocks 7, which are respectively connected to the two sides of the outer cylinder 1. The two rotating blocks 7 are respectively rotatably connected to two brackets 8, and the two brackets 8 are both connected to the base 5. The outer cylinder 1 can be rotated above the base 5 through the rotational cooperation between the rotating blocks 7 and the brackets 8.

[0027] The utility model also includes a spring support seat 6 and a lifting device 9. The fixed end of the spring support seat 6 is connected to the base 5, and the telescopic end of the spring support seat 6 is hinged to the outer cylinder 1. The spring support seat 6 is composed of a fixed base, a spring, a guide column and a connecting piece. The spring is sleeved on the outer wall of the guide column, and the guide column is made of elastic material. The two ends of the spring and the guide column are respectively connected to the fixed base and the connecting piece. The connecting piece is hinged to the bottom of the outer cylinder 1, and the fixed base is connected to the base 5. When adjusting the angle of the outer cylinder 1, the fixed end of the lifting device 9 is connected to the base 5, and the telescopic end of the lifting device 9 is slidably connected to the outer cylinder 1. The telescopic end of the lifting device 9 is connected to a slider. The slider is slidably matched with the slide groove provided at the bottom of the outer cylinder 1. When the lifting device 9 is lifted or lowered, the slider will be driven to slide in the slide groove, so that the angle between the outer cylinder 1 and the base 5 changes with the lifting of the lifting device 9. When the tea leaves need to be dumped after the withering is completed, starting the lifting device 9 can make one side of the outer cylinder 1 rise, and the other side of the outer cylinder 1 will compress the spring to shrink the spring. At this time, the outer cylinder 1 will tilt, and the tea leaves inside the withering cylinder 2 can slide along the inner wall. When withering, the outer cylinder 1 is adjusted to be horizontal, and the lifting device 9 and the spring support seat 6 can support the outer cylinder 1 to maintain stability during withering and prevent the outer cylinder 1 from shaking.

[0032] The fixed end of the motor 10 is connected to the outer cylinder 1, and the output end of the motor 10 is transmission-connected to the rotating shaft 16. One side of the rotating shaft 16 passes through the outer cylinder 1 and the withering cylinder 2. The outer wall of the rotating shaft 16 is connected to a plurality of stirring rods 15. The stirring rods 15 aligned on the same side are all connected to the scraper 14. When the tea leaves are withered, the rotating shaft 16 can be driven to rotate by starting the motor 10, and the stirring rods 15 connected to the outer wall of the rotating shaft 16 will rotate along with it, thereby stirring the tea leaves inside the withering cylinder 2. When the stirring rods 15 rotate, the scraper 14 will also rotate along with it. The outer side of the scraper 14 is close to the inner wall of the withering cylinder 2, and when it rotates along the inner wall of the withering cylinder 2, it can scrape off the tea leaves adsorbed on the inner wall of the withering cylinder 2.

[0033] In an optional embodiment, the scraper 14 is made of an elastic material so as not to damage the tea leaves when scraping them.

[0034] Embodiment 3

[0035] like Figure 2-3 As shown, the tea-tea-withering device proposed by the present invention, compared with the first embodiment, the present embodiment further discloses the structure of a heating mechanism, the heating mechanism includes a ventilation pipe 11, an exhaust fan 13 and a heating device 17;

[0036] One end of the ventilation pipe 11 is connected to the outer cylinder 1, and the other end of the ventilation pipe 11 is connected to the heating chamber 12. Both ends of the ventilation pipe 11 are connected to the interior of the withering cylinder 2 and the heating chamber 12 respectively. The exhaust fan 13 and the heating device 17 are both connected to the heating chamber 12. The heating device 17 is installed on the left side of the exhaust fan 13. A through hole 18 is provided on one side of the withering cylinder 2. One end of the ventilation pipe 11 passes through the outer cylinder 1 and is connected to the interior of the withering cylinder 2 through the through hole 18.

[0037] The exhaust fan 13 draws air into the heating chamber 12. The air is heated by the heating device 17 and becomes hot air. The hot air enters the interior of the withering tube 2 through the through hole 18 along the ventilation pipe 11 to increase the temperature inside the withering tube 2. The tea leaves are evenly exposed to the hot air, which can increase the withering rate of the tea leaves.

[0038] It should be noted that the heating device 17 may be an electric heating tube.

[0039] To sum up, when the tea leaves are withered, first adjust the outer cylinder 1 to a horizontal level by adjusting the lifting device 9, unscrew the closed window 3, put the tea leaves into the withering cylinder 2 through the round hole on one side of the withering cylinder 2, and then screw in the closed window 3, start the motor 10, drive the rotating shaft 16 to rotate, and the scraper 14 and the stirring rod 15 will rotate accordingly, and then start the exhaust fan 13 and the heating device 17, and the exhaust fan 13 will suck air into the heating chamber 12, and the air will become hot air after being heated by the heating device 17, and the hot air will enter the withering cylinder 2 through the ventilation pipe 11, so that the temperature inside the withering cylinder 2 can be increased. At this time, the tea leaves in the withering cylinder 2 are stirred and heated under the cooperation of the stirring mechanism and the heating mechanism, which improves the withering rate of the tea leaves. While stirring the tea leaves, The scraper 14 scrapes off the tea leaves adsorbed on the inner wall of the withering tube 2 to prevent the tea leaves from being adsorbed on the inner wall of the withering tube 2 for a long time and being damaged due to excessive heat. After the withering is completed, one end of the outer tube 1 is adjusted by the lifting device 9 so that the end of the withering tube 2 connected to the closed window 3 is facing the ground, and the closed window 3 is screwed out. At this time, the tea leaves can fall out of the withering tube 2. While discharging, the motor 10 and the exhaust fan 13 can be turned on, and the heating device 17 can be turned off. The rate of tea leaf discharge can be increased by blowing the tea leaves outward by introducing air. The scraper can make the tea leaves adsorbed on the inner wall of the withering tube 2 fall off, so that the tea leaves in the withering tube 2 can fall out quickly and will not be damaged due to staying in the withering tube 2 for a long time. This has the effect of improving the quality of the tea leaves after withering.

[0040] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
