Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a hot air uniform distribution device for a black tea drying equipment includes a drying chamber 1, a rotating assembly 2, and a hot air distribution assembly 5. The rotating assembly 2 is installed on the lower middle side of the drying chamber 1. The rotating assembly 2 includes a drive motor 201, a rotating shaft 202, and support rods 203. The rotating shaft 202 is provided on the upper side of the drive motor 201, and two support rods 203 are symmetrically fixed on the outer side of the rotating shaft 202. The support rods 203 have an "L" shape structure. A material rack 3 is provided on the upper side of the rotating shaft 202. The material rack 3 is a hollow circular structure with an opening on the upper side. Sliding frames 4 are fixed on both sides of the material rack 3, and the sliding frames 4 are sleeved on the outer side of the support rods 203. A movable cover plate 10 is installed on the other upper side of the drying chamber 1. Furthermore, a sealing layer is provided between the movable cover plate 10, the fixed cover plate 8, and the drying box 1. An air outlet pipe 11 is connected to the upper rear side of the movable cover plate 10, and a handle 12 is fixed to the upper middle part of the movable cover plate 10. The material rack 3 is a hollow circular structure with an opening on the upper side, which facilitates the even spreading of black tea. The sliding frames 4 on both sides of the material rack 3 are fitted on the upper side of two support rods 203 with an "L" shape structure, which facilitates the positioning of the material rack 3. This allows several material racks 3 to be stacked stably layer by layer under the action of gravity. The drive motor 201 and the rotating shaft 202 facilitate the rotation of the two support rods 203, which in turn drives the material rack 3 to rotate at a uniform speed, so as to cooperate with the hot air diversion component 5 to evenly dry the black tea inside several material racks 3.

[0023] like Figures 2-4As shown, a hot air distribution assembly 5 is provided inside the drying oven 1. The hot air distribution assembly 5 includes a hot air ring 501, air nozzles 502, connecting pipes 503, a fixing plate 504, and an air supply pipe 505. The hot air ring 501 and the drying oven 1 are in a concentric circular structure. Air nozzles 502 are evenly distributed in an array on the inner side of the hot air ring 501. A connecting pipe 503 is fixed above one side of the hot air ring 501. A fixing plate 504 is installed on one side of the top of the connecting pipe 503. An air supply pipe 505 is connected to the upper side of the connecting pipe 503. The air supply pipe 505 is interconnected with the hot air ring 501 through the connecting pipe 503. The hot air ring 501 is slidably connected to the inner wall of the drying oven 1. A support block 6 is fixed to one side of the outer side of the drying oven 1. An electric telescopic rod 7 is installed on the upper side of the support block 6. The top of the electric telescopic rod 7 is fixedly connected to the fixed plate 504. A fixed cover plate 8 is fixed on one side of the upper side of the drying box 1, and a through groove 9 is opened on one side of the fixed cover plate 8. The connecting pipe 503 passes through the through groove 9 and is slidably connected to the connecting pipe 503. At the same time, the air supply pipe 505 is located on the upper side of the fixed cover plate 8. The air supply pipe 505 is a flexible hose and is connected to a hot air box. It can send hot air into the interior of the hot air ring 501 through the connecting pipe 503. The air is then evenly discharged through several air outlets 502 arranged in an array on the inner side of the hot air ring 501. At the same time, the extension and retraction of the electric telescopic rod 7 facilitates the raising and lowering of the connecting pipe 503 and the hot air ring 501, thereby blowing air onto the multi-layer material rack 3 inside the drying box 1. The hot air is distributed relatively evenly, and excess airflow inside the drying box 1 can be discharged through the air outlet pipe 11.

[0024] In summary, as Figures 1-4 As shown, the hot air uniform distribution device of this black tea drying equipment can be used by first opening the movable cover plate 10, then fitting the sliding frames 4 on both sides of the material rack 3 onto the upper side of the two "L"-shaped support rods 203 to position the material rack 3, then evenly spreading the black tea inside the material rack 3, and setting up several material racks 3 layer by layer to ensure stable stacking, and then closing the movable cover plate 10. The air supply pipe 505 is a flexible hose and is connected to a hot air box, which can send hot air into the interior of the hot air ring 501 through the connecting pipe 503, and then evenly distributing the hot air through several air outlets 502 arranged in an array inside the hot air ring 501. The hot air is evenly distributed, and the extension and retraction of the electric telescopic rod 7 can drive the raising and lowering of the connecting pipe 503 and the hot air ring 501, thereby blowing air onto the multi-layer material racks 3 inside the drying chamber 1. The hot air is evenly distributed. The drive motor 201 and the rotating shaft 202 can drive the rotation of the two support rods 203, which in turn can drive the material racks 3 to rotate at a uniform speed. This works in conjunction with the hot air distribution component 5 to evenly dry the black tea inside several material racks 3. Excess airflow inside the drying chamber 1 can be discharged through the air outlet pipe 11. This completes the use of the hot air even distribution device of the black tea drying equipment.
