Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea processing technology, and in particular to a drum-type tea cooling and rehumidification machine. Background Technology
[0002] In tea processing, tea leaves that have undergone high-temperature treatments such as fixation and drying are typically at high temperatures and have extremely uneven moisture distribution. If they are directly introduced into subsequent processes such as rolling and fermentation, the excessively high temperatures will destroy the active substances in the tea leaves, affecting their aroma and taste; while uneven moisture distribution will lead to uneven stress during rolling, resulting in excessive broken tea leaves or poor shaping. Therefore, uniform and efficient cooling and rehumidification of high-temperature tea leaves is a crucial step in improving tea quality.
[0003] Currently, tea cooling and rehumidification equipment on the market has many shortcomings. Some equipment adopts a split design, with cooling and rehumidification processes carried out separately, requiring multiple transfers of tea leaves. This not only increases labor intensity but also easily leads to contamination or moisture loss of the tea leaves during transfer, affecting the processing effect.
[0004] Therefore, it is extremely important to provide a compact, uniformly cooled and rehydrated, and stably operating drum-type tea cooling and rehydration machine. Utility Model Content
[0005] The purpose of this invention is to provide a drum-type tea cooling and rehumidification machine, which integrates the cooling component and the rehumidification component in the same drum, so that the tea can be cooled and rehumidified simultaneously in one conveying process, eliminating the need for multiple transfers, reducing the time interval between processes and labor intensity, and greatly improving processing efficiency.
[0006] The objective of this utility model is achieved through the following technical solution:
[0007] A drum-type tea cooling and rehumidification machine includes a frame, a drum assembly, a cooling assembly, a rehumidification assembly, and a feeding assembly mounted on the frame; the drum assembly includes a drum that is rotatably and inclinedly mounted on the frame, a plurality of lifting plates mounted on the inner wall of the drum, and a drive assembly for driving the drum to rotate on the frame; the two open ends of the drum are a feeding port and a discharging port, respectively.
[0008] The cooling assembly includes a cooler fan mounted on the frame, a first air duct at the air outlet of the cooler fan, a second air duct at the air outlet of the first air duct and extending into the inside of the drum, and a plurality of cooling nozzles on the side wall of the second air duct.
[0009] The rehumidification assembly includes a humidifier mounted on the frame, a first delivery pipe mounted at the mist outlet end of the humidifier, a second delivery pipe mounted at the mist outlet end of the first delivery pipe and located inside the second air duct, a plurality of third delivery pipes mounted on the side wall of the second delivery pipe, and a plurality of rehumidification nozzles mounted at the mist outlet end of the third delivery pipe.
[0010] Preferably, the drive assembly includes a gear ring disposed on the outer wall of the drum, a motor disposed on the frame, a gear disposed at the output end of the motor and meshing with the gear ring, a journal disposed at both ends of the drum, a plurality of first support rods disposed between the journal and the inner wall of the drum, and a support wheel disposed on the frame and rotatably connected to the journal; a connecting pipe is fixedly disposed at one end of the second air duct near the discharge port, a connecting plate is disposed inside the journal disposed at the discharge port, the connecting pipe and the connecting plate are rotatably connected, and the end of the connecting pipe away from the second air duct passes through the discharge port and extends to the outside of the drum.
[0011] Preferably, both ends of the second air duct pass through the journal and extend to the outside of the drum, and one end of the second air duct near the feed inlet is connected to the frame by a second support rod.
[0012] Preferably, a connecting plate is provided inside the journal located in the discharge port, and the connecting plate is rotatably connected to the second air duct; multiple discharge channels are formed between the multiple first support rods provided on the journal located at the discharge port.

[0015] Preferably, on the two sides of the baffle and the journal that are close to each other, one side is provided with a first slider and the other side is provided with a groove that slides and engages with the first slider.
[0016] Preferably, the feeding assembly includes a feeding hopper mounted on the frame via a third support rod, and the bottom end of the feeding hopper is provided with a retractable feeding pipe that can extend into the roller feed inlet.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. This utility model integrates the cooling component and the rehumidification component in the same drum, so that the tea leaves can be cooled and rehumidified simultaneously during one conveying process, eliminating the need for multiple transfers, reducing the time interval between processes and labor intensity, and greatly improving processing efficiency.
[0019] 2. As the drum rotates, the lifting plates continuously turn the tea leaves, allowing them to rise fully and come into full contact with the cold air and water mist in the space. The cooling nozzles and rehumidification nozzles are distributed on the side wall of the air duct, which can evenly diffuse the cold air and water mist into the inside of the drum, avoiding the problem of local cooling or insufficient rehumidification, and ensuring the consistency of tea processing quality.
[0020] 3. The second conveying pipe of the rehumidification component is set inside the second air duct of the cooling component, forming a nested structure, which greatly saves the internal space of the drum, making the equipment structure more compact and reducing the equipment's footprint.

Detailed Implementation
[0025] Example 1
[0026] A drum-type tea cooling and rehumidification machine, such as Figure 1 As shown, the system includes a frame 1 (which is rectangular in shape), a roller 2 assembly, a cooling assembly, a rehumidification assembly, and a feeding assembly mounted on the frame 1. The roller 2 assembly includes a roller 2 that is rotatably and inclinedly mounted on the frame 1, multiple lifting plates (existing technology, not shown in the figure) mounted on the inner wall of the roller 2, and a drive assembly that drives the roller 2 to rotate on the frame 1. The two open ends of the roller 2 are the feed inlet (high end of the roller 2) and the discharge outlet (low end of the roller 2), respectively.
[0027] like Figure 1 As shown, the cooling assembly includes a cooler 3 mounted on the frame 1, a first air duct 4 mounted at the air outlet of the cooler 3, a second air duct 5 mounted at the air outlet of the first air duct 4 and extending into the inside of the roller 2, and a plurality of cooling nozzles 6 mounted on the side wall of the second air duct 5.
[0028] The rehumidification assembly includes a humidifier 7 mounted on the frame 1, a first delivery pipe 8 mounted at the mist outlet of the humidifier 7, a second delivery pipe 9 mounted at the mist outlet of the first delivery pipe 8 and located inside the second air duct 5, a plurality of third delivery pipes 10 mounted on the side wall of the second delivery pipe 9, and a plurality of rehumidification nozzles 11 mounted at the mist outlet of the third delivery pipe 10.
[0029] in, Figure 1 The driver component is not drawn.
[0030] Furthermore, such as Figure 2 and Figure 3 As shown, the drive assembly includes a gear ring 23 disposed on the outer wall of the roller 2, a motor 14 disposed on the frame 1 (the frame 1 is provided with a motor frame, and the motor 14 is fixed on the motor frame; the motor frame is prior art and is not shown in the figure), a gear 15 disposed at the output end of the motor 14 and meshing with the gear ring 23, and journals 17 disposed at both ends of the roller 2 (e.g., ...). Figure 1 As shown, the internal structure is hollow, and multiple first support rods 18 are disposed between the journal 17 and the inner wall of the roller 2, and support wheels 16 (such as those mounted on the frame 1 and rotatably connected to the journal 17) are provided. Figure 3 (as shown); a connecting pipe is fixedly installed at one end of the second air duct 5 near the discharge port, and a connecting plate 20 is installed inside the journal 17 at the discharge port. The connecting pipe and the connecting plate 20 are rotatably connected. The end of the connecting pipe away from the second air duct 5 passes through the discharge port and extends to the outside of the roller 2.
[0031] Furthermore, such as Figure 1 As shown, both ends of the second air duct 5 pass through the journal 17 and extend to the outside of the drum 2. One end of the second air duct 5 near the feed inlet is connected to the frame 1 by the second support rod 19, so that the second air duct 5 remains fixed during the rotation of the drum 2, which further improves the stability of the operation of the cooling component and the rehumidification component, avoids the impact of air duct shaking on the nozzle spraying effect, and enhances the load-bearing capacity of the air duct.
[0032] Working principle: The high-temperature treated tea leaves are fed into the feed inlet of drum 2 via the feeding assembly. Then the motor is turned on.
[0033] 14. Through the meshing transmission between the gear ring 23 and the gear 15, the roller 2 is driven to rotate on the frame 1. During this process, the journal...
[0034] The roller 17 and support roller 16 are rotatably connected (with a bearing between them). Because the roller 2 is inclined, the tea leaves move slowly along the axis of the roller 2 towards the discharge port under their own weight and the action of the lifting plates on the inner wall of the roller 2. Simultaneously, they are continuously lifted and scattered by the tumbling action of the lifting plates, achieving thorough mixing. This ensures the stability of the roller 2's rotation and the high efficiency of power transmission.
[0035] In the cooling assembly, the cold air generated by the air cooler 3 is delivered to the second air duct 5 through the first air duct 4, and then evenly sprayed into the inside of the drum 2 through multiple cooling nozzles 6 on the side wall of the second air duct 5, so as to fully contact the tea leaves being turned over, absorb the heat of the tea leaves, reduce the temperature of the tea leaves, and achieve the cooling function.
[0036] In the rehumidification assembly, the water mist generated by the humidifier 7 is transported via the first conveying pipe 8 to the second conveying pipe 9 located inside the second air duct 5. It is then diverted through multiple third conveying pipes 10 on the side wall of the second conveying pipe 9, and finally sprayed into the interior of the drum 2 by the rehumidification nozzle 11. The water mist comes into contact with the tea leaves during the cooling process, allowing the tea leaves to absorb moisture appropriately, achieving the purpose of rehumidification and ensuring even moisture distribution in the tea leaves.
[0037] During the process of moving the tea leaves to the discharge port, they undergo cooling and rehydration treatment before finally being discharged from the discharge port.
[0038] Example 2
[0039] Based on Example 1, such as Figure 1 As shown, a connecting plate 20 is installed inside the journal 17 located within the discharge port, and the connecting plate 20 is rotatably connected to the second air duct 5. Multiple first support rods 18 installed on the journal 17 at the discharge port form multiple discharge channels. The connecting plate 20 at the discharge port can seal the inside of the journal 17, preventing tea leaves from falling out of the journal 17 under gravity. Simultaneously, the rotatable connection between the connecting plate 20 and the connecting pipe reduces friction and wear between them, ensuring smooth rotation of the roller 2. The multiple discharge channels formed between the first support rods 18 ensure that the tea leaves can be smoothly discharged from the discharge channels, avoiding blockages and improving discharge efficiency. Furthermore, in actual implementation, the end of the connecting pipe furthest from the second air duct 5 passes through the journal 17 at the discharge port and extends to the outside of the journal 17. The connecting pipe extending to the outside of the journal 17 is fixedly connected to the frame 1 via the second support rod 19 (not shown in this structural diagram).
[0040] Furthermore, a baffle 21 is slidably fitted on the journal 17 located at the discharge port. During the rehydration process, the baffle 21 can block the discharge port, preventing the tea leaves from being discharged from the discharge channel before they have been fully rehydrated.
[0041] Furthermore, the baffle 21 and the discharge end of the roller 2 are magnetically connected. This allows the baffle 21 to connect with and rotate with the discharge end of the roller 2 during the rehydration process, preventing material from falling through the gap between the baffle 21 and the discharge end of the roller 2. After rehydration is complete, the baffle 21 can be directly separated from the discharge end of the roller 2, and then the baffle 21 can be slid away from the roller 2, thus exposing the discharge port and ensuring smooth material discharge.
[0042] Furthermore, on the two sides of the baffle 21 and the journal 17 that are close to each other, one side is provided with a first slider, and the other side is provided with a sliding groove 22 that slides and engages with the first slider. This structure enables the baffle 21 to slide and rotate more smoothly, the adjustment process is simple and labor-saving, and at the same time ensures the stability of the connection between the two, preventing the baffle 21 from shifting during equipment operation.
[0043] Furthermore, the feeding assembly includes a feeding hopper 12 mounted on the frame 1 via a third support rod. The bottom end of the feeding hopper 12 is provided with a retractable feeding pipe 13 that extends into the feeding inlet of the roller 2. The feeding pipe 13 is equipped with a locking device (any locking device in the prior art, such as the locking device on a camera tripod) to ensure that it does not arbitrarily extend or retract along the axial direction. The retractable design of the feeding pipe 13 allows the roller 2 to extend during feeding, enabling the outlet end of the feeding pipe 13 to be guided into the roller 2 along the gap between the multiple first support rods 18 at the feeding inlet, ensuring that the tea leaves smoothly enter the roller 2 and preventing tea leaves from spilling during the feeding process. When feeding is not required, the feeding pipe 13 is retracted to avoid interfering with the rotation of the roller 2.
[0044] Furthermore, such as Figure 1 As shown, the top surface of the frame 1 is provided with a collection trough 24 for collecting tea leaves after they have regained moisture.
