[0021] 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.

[0022] like Figures 1 to 5 As shown, a tea fermentation machine for tea processing includes a cabinet 1. A cabinet door 2 is installed at the front end of the cabinet 1. Multiple circular fermentation frames 3 arranged from bottom to top are detachably installed inside. An exhaust pipe 4 is located at the top. A PLC controller 14 is installed on the cabinet door 2. A temperature and humidity sensor is installed at the top inside the cabinet 1. A partition 5 is fixedly connected to the lower inner part, and two fixed pipes 15 are symmetrically fixed to the rear inner part. Several through holes are opened on the surface of the fixed pipes 15. A hot air blower 16 and a humidifier 17 are located below the partition 5. The output ends of the hot air blower 16 and the humidifier 17 are respectively connected to the two fixed pipes 15. An inspection door 18 is installed at the lower front end of the cabinet 1, and several ventilation holes are opened on the inspection door 18.

[0023] When the hot air blower 16 is working, it inputs hot air into a fixed pipe 15. The hot air is blown into the cabinet 1 through the ventilation hole to heat the inside of the cabinet 1. When the humidifier 17 is working, it inputs steam into another fixed pipe 15. The steam is blown into the cabinet 1 through the ventilation hole to humidify the inside of the cabinet 1.

[0024] To prevent water backflow in the fixed pipe 15, the air inlet pipe at the bottom of the fixed pipe 15 extends into the interior of the fixed pipe 15 and is at least 10cm higher than the bottom surface of the fixed pipe 15. The lower rear end of the fixed pipe 15 is provided with a drain outlet that runs through the rear end face of the cabinet 1, and a sealing plug is installed at the drain outlet.

[0025] Two ear plates 19 are symmetrically fixed to the upper side of the fermentation frame 3. A handle 20 is fixed to the top of the ear plate 19. Multiple sets of support columns 6, which are used to position the fermentation frame 3, are fixed to the inside of the cabinet 1 on both sides. A limiting plate 21 that fits the surface of the fermentation frame 3 is fixed to the end of the support column 6. A positioning groove that matches the ear plate 19 is opened on the top surface of the support column 6.

[0026] Each fermentation frame 3 is equipped with a stirring assembly at its top, and multiple stirring assemblies are connected end to end. A motor 7 is installed at the bottom of the partition 5, and the output end of the motor 7 is connected to a drive shaft 8. The stirring assembly is detachably connected to the drive shaft 8. The stirring assembly includes a rotating shaft 9, a circular plate 10 is fixedly connected to the top of the rotating shaft 9, and a protrusion is fixedly connected to the lower side. Multiple horizontal plates 11 are fixedly connected to the edge of the circular plate 10, and multiple stirring rods 12 are fixedly connected to the bottom of the horizontal plates 11. A fixing cylinder 13 is fixedly connected to the top of the circular plate 10. A limiting groove adapted to the protrusion is opened on the inner side of the fixing cylinder 13. The stirring rods 12 at the bottom of each horizontal plate 11 are staggered, and the stirring rods 12 at the bottom of multiple horizontal plates 11 are staggered.

[0027] The rotating shaft 9 passes through the fermentation frame 3, and a limiting cylinder 22 is fixedly connected inside the fermentation frame 3 and sleeved on the outside of the rotating shaft 9. A counterweight 23 is installed above the circular plate 10 near the top of the cabinet 1. The bottom of the counterweight 23 has a groove that matches the fixed cylinder 13. A connecting cylinder 24 is fixedly connected to the top of the rotating shaft 9. A limiting groove that matches the protrusion is opened on the inner side of the connecting cylinder 24. In order to allow the rotating shaft 9 to pass through the limiting cylinder 22, a sliding groove that matches the protrusion is opened on the inner side wall of the limiting cylinder 22.

[0028] The fermentation frame 3 is placed between two support columns 6. The two limiting plates 21 can prevent the fermentation frame 3 from shaking. The motor 7 drives the transmission shaft 8 to rotate. The transmission shaft 8 drives the rotating shaft 9 to rotate through the connecting cylinder 24. The rotating shaft 9 drives the circular plate 10, the horizontal plate 11 and the stirring rod 12 to rotate, which can agitate the tea leaves, making the tea leaves heat up and react more evenly, and preventing the tea leaves from clumping, thus improving the fermentation quality of the tea leaves.

[0029] In practical use, tea leaves are laid in the fermentation frame 3, and then the fermentation frame 3 is placed between a set of support columns 6 at the bottom of the cabinet 1. The bottom of the rotating shaft 9 is then inserted into the connecting cylinder 24 after passing through the limiting cylinder 22. A new fermentation frame 3 is then placed on top of the fermentation frame 3, and the bottom of the new rotating shaft 9 is inserted into the fixing cylinder 13 after passing through the limiting cylinder 22. The fermentation frame 3 and rotating shaft 9 are installed in the same way. Finally, the counterweight 23 is installed on the top circular plate 10. The hot air blower 16 and humidifier 17 work to heat and humidify the inside of the cabinet 1. The temperature and humidity sensor installed on the top of the cabinet 1 monitors the temperature and humidity. When the set value is reached, the hot air blower 16 and humidifier 17 stop working. The motor 7 simultaneously drives multiple stirring components to stir the tea leaves inside the fermentation frame 3, improving the uniformity of tea fermentation and improving the quality of tea fermentation.
