[0027] As an embodiment of the present invention, a black tea fermentation process comprises the following steps: S1: Open the cylinder cover 11, open the support plates 131 in sequence through the fixing mechanism 2, and place the tea leaves on the multiple fermentation trays 13 in sequence; S2: Start the motor 43 to drive the air pipe 4 to drive the multiple stirring pipes 41 to rotate, and start the air pump 45 to blow gas into the stirring pipe 41 and spray it out through the air hole 42 to stir the tea leaves, and gradually reduce the gas pressure to make the tea leaves evenly spread on the fermentation plate 13; S3: After each fermentation period, the tea leaves are stirred by the stirring tube 41, and the driving mechanism 32 drives the baffle 1 34, the baffle 2 35, the block 1 31, and the block 2 33 to move closer to the center of the fermentation tray 13, thereby reducing the area of ​​the tea leaves on the fermentation tray 13 and increasing the thickness of the tea leaves; S4: After fermentation is completed, the plurality of support plates 131 are separated from top to bottom by the fixing mechanism 2, so that the tea leaves fall into the material receiving drawer 121 and are taken out by the staff.

[0028] Working principle: like Figure 1-Figure 4 As shown, when the fermentation device is used, the cylinder cover 11 on the top of the fermentation cylinder 1 is opened, and a proper amount of tea leaves are poured onto the top fermentation tray 13, and then the cylinder 23 is started to drive the sliding ring 22 to move, so that the limiting sleeve 24 on the sliding ring 22 drives the fixing rod 21 to rotate, thereby driving the supporting plate 131 to rotate downward, so that the multiple supporting plates 131 are separated, and firstly, the multiple supporting plates 131 except the bottom supporting plate 131 are separated by the fixing mechanism 2, so that the tea leaves fall from the top of the fermentation cylinder 1 to the bottom fermentation tray 13, and then the second supporting plate 131 at the bottom is merged by the fixing mechanism 2, and then a proper amount of tea leaves are put in, and the fermentation trays 13 are all filled with tea leaves in turn; After the tea leaves are placed, the motor 43 is started to drive the empty tube 4 to drive the multiple stirring tubes 41 to rotate; at the same time, the air pump 45 is started to blow gas into the empty tube 4 through the air tube 46 and the empty chamber 44, and the gas flows to each stirring tube 41 through the empty tube 4 and is ejected from the air hole 42 to blow up the tea leaves, so that the tea leaves are evenly mixed in the air, and the pressure of the gas input by the air pump 45 is gradually reduced, so that the tea leaves naturally fall on the fermentation plate 13, so that the tea leaves maintain a uniform thickness and density.

[0029] It should be noted that two adjacent fermentation trays 13 are closed by baffle 1 34, baffle 2 35, block 1 31, block 2 33, and the top baffle 1 34, baffle 2 35, block 1 31, block 2 33 cooperate with the tube cover 11 to close the fermentation tray 13. Therefore, the tea leaves will not scatter randomly after being blown up, and will always be surrounded by baffle 1 34, baffle 2 35, block 1 31, block 2 33 and the fermentation tray 13.

[0030] like Figure 4 , Figure 7 , Fig. 9 As shown in the figure, the tea leaves are allowed to ferment in the fermentation cylinder 1. When the tea leaves need to be turned over, the air pump 1 45 and the motor 1 43 are started to drive the stirring tube 41 to stir the tea leaves through the air holes, and the tea leaves at the bottom are blown into the air; at the same time, the air pump 2 39 is started to blow the air into the block 1 31 through the air pipe 2 38 and the air pipe 3 311, and the air is ejected through the air hole 2 36 on the block 1 31; since the block 2 33 is connected to the block 1 31, the air filled into the block 1 31 The gas flows into the second block 33 and is ejected through the third air hole 37. The gas ejected from the first air hole 42 and the second air hole 36 blows the tea leaves on the edge of the fermentation tray 13 toward the center of the fermentation tray 13, and at the same time blows the tea leaves falling from the air toward the center of the fermentation tray 13, and then the tea leaves are blown up by the gas ejected from the first air hole 42 on the stirring tube 41. In this reciprocating manner, the tea leaves in the center of the tea pile are evenly mixed with the tea leaves on the outer layer of the tea pile, so that the tea leaves are fully and evenly exposed to oxygen, thereby ensuring the quality of fermentation.

[0031] After stirring for a certain period of time, the air pump 2 39 is turned off, and only the air pump 1 45 is started, and the air pressure is gradually reduced so that the tea leaves are evenly spread on the fermentation tray 13 for the next step of fermentation.

[0032] The tea leaves are turned over by the gas ejected from the air hole 42 on the stirring tube 41, thereby reducing the damage to the tea leaves when turning over the tea leaves, improving the integrity of the tea leaves, and further improving the quality of the tea leaves.

[0033] The gas ejected by the first block 31 and the second block 33 further turns the tea leaves, thereby improving the uniformity of tea leaf mixing.

[0034] like Figure 4 , Figure 8As shown, each time the tea leaves are turned, the motor 2 326 is started to drive the rotating rod 1 322 to rotate, and the bevel gear 1 324 on the rotating rod 1 322 drives the rotating rod 2 323 to rotate by meshing with the bevel gear 2 325. Since one end of the rotating rod 2 323 is threadedly connected to the fixed tube 329, and the fixed tube 329 is slidably connected to the fixed cylinder 328, when the rotating rod 2 323 rotates, the fixed tube 329 is driven to move out of the fixed cylinder 328, and then the stopper 1 31 fixedly connected to the fixed tube 329 is driven to move toward the center of the fermentation tray 13; because the gears 3210 on multiple rotating rods 1 322 are connected by the gear ring 327, when one rotating rod 1 322 rotates, it drives multiple rotating rods 1 322 to rotate synchronously. The plurality of blocks 1 31 move synchronously toward the center of the fermentation tray 13, and the block 2 33 between the plurality of blocks 1 31, the baffle 1 34 on the block 1 31, and the baffle 2 35 move toward the center of the fermentation tray 13, thereby reducing the encirclement range of the fermentation tray 13 by the block 1 31, the block 2 33, the baffle 1 34, and the baffle 2 35, so that the area of ​​the tea leaves on the fermentation tray 13 is reduced, thereby increasing the thickness of the tea leaves on the fermentation tray 13. The greater the thickness, the greater the density, so that the thickness of the tea leaves is adjusted with the fermentation time. In the early stage of fermentation, the tea pile needs to be spread thinly and with low density to facilitate the reaction of the tea leaves with oxygen. In the later stage of fermentation, the tea leaves do not need too much oxygen, so they need to be spread thickly to promote the formation of the aroma of the tea leaves.

[0035] It should be noted that, during the movement of block 1 31 and block 2 33 , the gas ejected from block 1 31 and block 2 33 blows the tea leaves to prevent the tea leaves from getting stuck in the gap between block 1 31 and block 2 33 and the fermentation tray 13 .

[0036] It should be noted that when two adjacent baffle plates 34 move toward the middle of the fermentation plate 13, the block 2 33 slides toward the inside of the block 1 31. Since the two adjacent baffle plates 33 are connected by a connecting rod 1 314, and one end of the connecting rod 1 314 is located in the limiting groove 132, the sliding distances of the two baffle plates 33 into the block 1 31 are the same, ensuring that when the block 1 31 moves, the two baffle plates 33 can stably move between the two adjacent baffle plates 31 to avoid misalignment affecting subsequent movement. Similarly, the two adjacent baffle plates 35 are rotatably connected by a connecting rod 2 315, and one end of the connecting rod 2 315 is located in the limiting groove 132, so that the two adjacent baffle plates 35 can move equidistantly.

[0037] As the fermentation time increases, the area of ​​the tea leaves in the fermentation tray 13 is gradually reduced, the thickness and density of the tea leaves are increased, and the quality of tea leaf fermentation is improved. In conjunction with the stirring tube 41, the thickness of the tea leaves can be changed and the tea leaves can be evenly spread on the fermentation tray 13, further improving the fermentation quality.

[0038] like Figure 1-Figure 3As shown, after fermentation is completed, the support plate 131 is separated from top to bottom by the fixing mechanism 2, so that the tea leaves fall into the material receiving drawer 121 below the fermentation cylinder 1. The staff can take out the fermented tea leaves by pulling out the material receiving drawer 121.
