[0002] Black tea is one of the six major tea categories in my country, and my country is also the birthplace of black tea. High-quality black tea should have a bright red color, a mellow and fragrant taste, and a pure and long-lasting aroma. Modern research shows that black tea contains a large amount of phenolic substances, which have antioxidant properties, lower blood lipids, inhibit arteriosclerosis, enhance capillary function, and have anti-mutagenic effects. Therefore, drinking black tea regularly is beneficial to human health. Drinking black tea can also increase the vitamin B1 content in the liver, which means that regular consumption of black tea helps promote the secretion of enzymes in the liver, helps liver cells function normally, and reduces the metabolic burden on liver cells. Black tea is a fully fermented tea, made from suitable new tea leaves through a series of processes including withering, rolling (cutting), fermentation, and drying. Every step in the preparation of black tea affects the quality of the tea leaves. Among them, fermentation is the key process that reflects the quality of black tea. The so-called fermentation of black tea is a series of chemical changes mainly involving the oxidation of polyphenolic compounds under the action of enzymes.

[0043] Preferably, the interior of the housing 1 is provided with two circular rings 312. A second annular groove is formed on the circular ring 312. A second fixing rod is fixedly connected to the inner wall of the housing 1. A second ball is fixedly connected to one end of the second fixing rod.

A temperature control lamp 313 is fixedly installed between the two circular rings 312. There are two temperature control lamps 313, and the two temperature control lamps 313 are symmetrically arranged between the two circular rings 312.

[0044] Preferably, the first rotating rod 33 has an internal cavity, and the housing 1 is provided with a temperature control mechanism 4. The temperature control mechanism 4 includes a hot air blower 41, an air outlet pipe 42, and a first air outlet 43.

[0047] Working principle: Open the lid, pour the tea leaves to be fermented into the fermentation tank 31, close the lid, and then close the lid 2. Start the motor 32, which drives the first rotating rod 33 to rotate. This, in turn, drives the sleeve 34 to rotate via the limit block and limit groove. The rotation of the sleeve 34 drives the turning rod 35 to rotate, thus turning the tea leaves in the fermentation tank 31. Simultaneously, the rotation of the first rotating rod 33 drives the second rotating rod 39 to rotate in the same direction via the pulley. The rotation of the second rotating rod 39 drives the main gear 310 and the cleaning roller 311 to rotate. The rotation of the main gear 310 drives the drive gear 38 to rotate in the opposite direction, thus driving the fermentation tank 31 to rotate in the opposite direction. Through the fermentation tank 31 and the first rotating rod 33, the tea leaves in the fermentation tank 31 rotate in the same direction. The reverse rotation of the rotating rod 33 makes the tea leaves inside the fermentation tank 31 turn more thoroughly. At the same time, when the fermentation tank 31 rotates in the opposite direction to the first rotating rod 33, the turning rod 35 moves left and right under the action of the surrounding groove 36 and the ball bearing 37, so that the tea leaves inside the fermentation tank 31 are turned more thoroughly. Meanwhile, when the second rotating rod 39 drives the cleaning roller 311 to rotate, it will clean the outer wall of the fermentation tank 31 to prevent the outer wall of the fermentation tank 31 from being blocked and affecting the air permeability of the tea leaves inside the fermentation tank 31. When the main gear 310 rotates, it will drive the ring 312 to rotate through the teeth, thereby driving the temperature control lamp 313 to rotate, so as to maintain a constant temperature for the tea leaves inside the fermentation tank 31, which is conducive to the fermentation of the tea leaves.

[0048] The temperature and humidity sensor 46 senses the temperature and humidity of the tea leaves inside the fermentation tank 31. Based on the detected temperature, the hot air blower 41 is activated to blow hot air into the interior of the fermentation tank 31 through the first air outlet 43 and the second air outlet 45. This controls the temperature of the tea leaves inside and in the middle of the tank while also providing ventilation.

[0049] Please see Figure 1-8 Based on the above embodiments, in another preferred embodiment of the present invention, the housing 1 is provided with a humidity control mechanism 5. The humidity control mechanism 5 includes a water tank 51, a water pump 52, a water pipe 53, and an atomizing nozzle 54. The water tank 51 is located on the back of the housing 1. The water pump 52 is fixedly installed on the top of the water tank 51, and the input end of the water pump 52 is connected to the water tank 51. One end of the water pipe 53 is connected to the output end of the water pump 52, and the other end of the water pipe 53 passes through the back of the housing 1 and is connected to the atomizing nozzle 54.

[0050] Preferably, the humidity control mechanism 5 further includes a fixed block 55, a reciprocating screw 56, and a movable block 57. The fixed block 55 is fixedly connected to the inner wall of the housing 1. The reciprocating screw 56 passes through the fixed block 55 through a bearing and is rotatably connected to the fixed block 55. The reciprocating screw 56 is connected to the first rotating rod 33 through a pulley. The movable block 57 is threaded on the reciprocating screw 56 and is slidably connected to the inner wall of the housing 1. The movable block 57 is fixedly connected to the water pipe 53.

[0051] Working principle: The temperature and humidity sensor 46 senses the humidity of the tea leaves inside the fermentation tank 31. When the humidity of the tea leaves is low, the water pump 52 is activated to spray clean water from the water tank 51 through the water pipe 53 and then through the atomizing nozzle 54 into the fermentation tank 31 for humidification. This controls the humidity of the tea leaves inside the fermentation tank 31. At the same time, when the first rotating rod 33 rotates, it drives the reciprocating screw 56 to rotate through the pulley, thereby driving the moving block 57 to move left and right. The moving block 57 drives the atomizing nozzle 54 to move, thereby making the humidification of the atomizing nozzle 54 more uniform. After the tea leaves have finished fermenting, the aroma of the fermented tea leaves will be discharged from the chamber 1 through the ventilation hole. The aroma is detected by the odor scanner 7. When the detected aroma meets the set aroma, the warning light 8 will be activated to remind the operator to avoid the fermentation time being too long and affecting the fermentation effect.
