Description

Technical Field

[0001] This application belongs to the technical field of tea processing equipment, and in particular relates to a cooling device and cooling method for a tea cooling conveyor. Background Technology

[0002] Fixing (or killing the green) is the most important step in tea processing. This process involves using high temperatures to destroy and inhibit the activity of oxidases in fresh tea leaves, thus stopping the oxidation of polyphenols and other enzymes. Simultaneously, it evaporates some of the moisture from the fresh leaves, facilitating rolling and shaping, and contributing to the development of a pleasant aroma. After fixing, the tea leaves must be cooled before proceeding to the next step. Because the temperature is high after fixing, if cooling is not timely, secondary fermentation can easily occur, causing the polyphenols and other internal components in the tea to oxidize rapidly, affecting the color and taste of the tea. The cooling device used after fixing is the main equipment for this process.

[0003] While existing cooling conveyors can cool tea leaves, they still have some drawbacks. For example, existing cooling conveyors do not effectively scatter the leaves during transport, resulting in severe leaf stacking. Furthermore, existing cooling conveyors typically use circular axial flow fans to directly blow air onto the tea leaves on the conveyor belt for cooling. The structure of the circular axial flow fan results in good cooling in the middle of the conveyor belt, but the cooling effect deteriorates towards the edges, leading to uneven cooling. Improvements are needed to address these issues. Summary of the Invention

[0004] The purpose of this application is to address the aforementioned technical problems by providing a cooling device for a tea cooling conveyor that can provide a uniform cooling effect and a better leaf-loosening effect.

[0005] This application provides a cooling device for a tea cooling conveyor, comprising: frame; The conveyor belt is mounted on the frame by winding and moving with the shaft. The conveyor belt is provided with a first conveying surface and a second conveying surface. The first and second conveying surfaces are distributed in a double-layer structure. The conveyor belt moves from the first conveying surface to the second conveying surface and then returns to the first conveying surface in a cyclical movement. A first fan assembly is mounted on the frame and is placed between a first conveying surface and a second conveying surface. The first fan assembly is used to blow away tea leaves that fall from the first conveying surface to the second conveying surface. The second fan assembly is mounted on the frame. The second fan assembly includes a partition structure for dividing and redirecting the airflow of the second fan assembly to act on the tea leaves on the second conveying surface. The material discharge port is installed on the frame and located at the end of the second conveyor surface.

[0006] The conveyor belt is movably mounted on the frame via a shaft. The belt's movement is controlled by the rotation of the shaft, which is used to transport tea leaves. The shaft is driven to rotate by a motor or other drive device. The conveyor belt uses a head-to-tail connection structure for cyclical movement. Both the first and second conveyor surfaces can move tea leaves from a lower position to a higher position. When tea leaves are placed on the first conveyor surface, they are moved to a higher position and then fall onto the second conveyor surface. During the descent, the air blown by the first fan assembly improves the dispersion effect, allowing the tea leaves to be more evenly distributed on the second conveyor surface. Compared to existing methods using mechanical structures, this method offers better leaf dispersion. Simultaneously, it can cool the tea leaves and prevent them from sticking to the conveyor belt, making cleaning convenient after production. When the tea leaves fall onto the second conveyor surface, they are transported by the conveyor belt. During this movement, the air blown by the second fan assembly evenly cools the tea leaves. This double cooling process ensures better cooling. After being transported to a higher position by the second conveyor surface, the tea leaves are discharged from the discharge port. By stacking the first and second conveyor surfaces on the frame, the compactness of the equipment is improved, further increasing space utilization. By using the same conveyor belt for both the first and second conveyor surfaces, one driving force is reduced, further improving energy efficiency. The second fan assembly uses a partition structure to redirect and divide the airflow delivered by the second fan assembly, further enhancing the cooling effect.

[0007] Furthermore, the first wind turbine assembly and the second wind turbine assembly include: A cylindrical body is mounted on a frame. The cylindrical body includes an air inlet and an air outlet. The air inlet is located at the end of the cylindrical body, and the air outlet is located on the side wall of the cylindrical body. The fan blades are installed inside the cylinder.

[0008] Furthermore, the first wind turbine assembly includes: The guide plate is placed at the air outlet corresponding to the first fan assembly and between the first conveying surface and the second conveying surface.

[0009] Furthermore, the rack also includes: The first baffle is placed on the frame and corresponds to the first conveying surface; The second baffle includes an observation window, which is movably mounted on the second baffle. The second baffle and the observation window have a mesh structure.

[0010] Furthermore, the rack also includes: The first collection box is located below the first conveying surface; The first guide surface is located below the first conveying surface and is connected to the first collection box; The second collection box is located below the second conveying surface; The second guide surface is located below the second conveying surface and is connected to the second collection box.

[0011] Furthermore, the partition structure includes: The housing is mounted on the frame, and one end of the housing is connected to the second fan assembly. The partition is installed inside the enclosure; End plate, installed at one end of the housing and away from the second fan assembly.

[0012] Furthermore, the partition structure also includes: The first slide rail is installed on the inner wall of the box; The first slide block is installed and connected to the partition and is slidably connected to the first slide rail; The second slide rail is installed inside the housing; The second slide block and the second slide rail are slidably connected; The third slide is hinged to the second slide; The third slide rail is installed on the partition; A connector is hinged between two partitions, and the connector is respectively hinged to the second slide of the left partition and the first slide of the right partition. The drive cylinder is installed between the two ends of the second slide rail and the housing.

[0013] This application also provides a cooling method for a cooling device of a tea cooling conveyor, the specific steps of which include: S1, place the tea leaves that need to be cooled at the lower end of the first conveyor surface, lift them by the conveyor belt and drop them from the upper end of the first conveyor surface to the second conveyor surface, and blow and cool the tea leaves by the first fan assembly during the falling process; S2, the tea leaves falling onto the second conveyor surface are lifted by the conveyor belt and passed through the partition structure, and the tea leaves on the second conveyor surface are cooled by the second fan assembly and the partition structure; S3, the tea leaves continue to rise on the second conveyor surface, fall at the upper end of the second conveyor surface, and are discharged through the discharge port.

[0014] The beneficial effects of this application are: 1. By dropping tea leaves from a height on the first conveyor surface to the second conveyor surface, the air blown by the first fan assembly during the falling process improves the dispersing effect of the tea leaves, allowing them to be more evenly scattered on the second conveyor surface. Furthermore, it makes it less likely for tea leaves to stick to the conveyor belt, making cleaning easier after production.

[0015] 2. After the tea leaves fall onto the second conveyor surface, they are transported by the conveyor belt. The tea leaves are then cooled evenly by the air blown out by the second fan assembly. This double cooling process ensures a better cooling effect for the tea leaves.

[0016] 3. The second fan assembly uses a partition structure to redirect and divide the airflow delivered by the second fan assembly, thereby further improving cooling efficiency.

[0017] 4. After the tea leaves are conveyed to a high position by the second conveyor surface, they are discharged from the discharge port. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0020] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0022] Example 1: like Figure 1 , Figure 2 As shown in the figure, this application embodiment provides a cooling device for a tea cooling conveyor, including: 100 racks; The conveyor belt 200 is mounted on the frame 100 by winding and moving with the shaft. The conveyor belt 200 is provided with a first conveying surface 210 and a second conveying surface 220. The first conveying surface 210 and the second conveying surface 220 are distributed in a double-layer structure. The conveyor belt 200 moves from the first conveying surface 210 to the second conveying surface 220 and then returns to the first conveying surface 210 in a cyclical movement. The first fan assembly 300 is mounted on the frame 100. The first fan assembly 300 is placed between the first conveying surface 210 and the second conveying surface 220. The first fan assembly 300 is used to blow away the tea leaves that fall from the first conveying surface 210 onto the second conveying surface 220. The second fan assembly 400 is mounted on the frame 100. The second fan assembly 400 includes a partition structure 410, which is used to divide and redirect the airflow of the second fan assembly 400 to act on the tea leaves on the second conveying surface 220. The material discharge port 500 is installed on the frame 100 and is located at the end of the second conveying surface 220.

[0023] The conveyor belt is movably mounted on the frame 100 via a shaft. The conveyor belt's movement is controlled by the rotation of the shaft, which is used to transport tea leaves. The shaft is driven to rotate by a motor or other drive device. The conveyor belt 200 uses a head-to-tail connection structure for cyclical movement. Both the first conveyor surface 210 and the second conveyor surface 220 can move tea leaves from a lower position to a higher position. When tea leaves are placed on the first conveyor surface 210, they are moved to a higher position and then fall onto the second conveyor surface 220. During the falling process, the air blown by the first fan assembly 300 improves the dispersing effect of the tea leaves, allowing them to be more evenly scattered on the second conveyor surface 220. Compared to existing methods using mechanical structures, this method offers better leaf dispersion and also... The first conveyor surface 210 and the second conveyor surface 220 are cooled, and tea leaves are less likely to stick to the conveyor belt 200, making cleaning easier after production. When the tea leaves fall onto the second conveyor surface 220, they are transported by the moving conveyor belt 200. During the movement, the air blown by the second fan assembly 400 cools the tea leaves evenly. This double cooling process results in better cooling effect. After being transported to a higher position by the second conveyor surface 220, the tea leaves are discharged from the discharge port 500. By stacking the first conveyor surface 210 and the second conveyor surface 220 on the frame 100, the compactness of the equipment is improved, further increasing space utilization. By using the same conveyor belt 200 for both the first and second conveyor surfaces 210 and 220, one driving force is reduced, further improving energy efficiency. The second fan assembly 400 uses a partition structure 410 to redirect and divide the airflow delivered by the second fan assembly 400, further improving the cooling effect.

[0024] Example 2: like Figure 1 , Figure 2 As shown, this application embodiment provides a cooling device for a tea cooling conveyor. In addition to the aforementioned technical features, the first fan assembly 300 and the second fan assembly 400 further include: The cylinder 310 is mounted on the frame 100. The cylinder 310 includes an air inlet 311 and an air outlet 312. The air inlet 311 is located at the end of the cylinder 310, and the air outlet 312 is located on the side wall of the cylinder 310. The fan blade 320 is installed inside the cylinder 310.

[0025] The cylinder 310 is mounted on the frame 100 using fasteners such as bolts and nuts. The fan blade 320 is installed inside the cylinder 310. The shaft of the fan blade 320 is mounted on the frame 100 via bearings and bearing seats, and is connected to a power source such as a drive motor to drive the fan blade 320 to rotate. The air inlet 311 of the cylinder 310 is located at both ends of the cylinder 310, and the air outlet 312 is located on the side wall of the cylinder 310. When the fan blade 320 rotates, it discharges the air inside the cylinder 310 from the air outlet 312 and then draws it back into the cylinder 310 through the air inlet 311. This achieves a uniform blowing effect in the width direction of the conveyor belt 200, further ensuring the uniformity of tea leaf distribution and cooling.

[0026] Furthermore, the first wind turbine assembly 300 includes: The guide plate 330 is placed at the air outlet 312 corresponding to the first fan assembly 300, and is located between the first conveying surface 210 and the second conveying surface 220.

[0027] The guide plate 330 is mounted on the frame 100 by bolts or other fasteners and corresponds to the air outlet 312 of the first fan assembly 300. The guide plate 330 is used to receive tea leaves falling from the first conveying surface 210 and guide the air volume blown out by the first fan assembly 300. The guide plate 330 improves the uniformity of the tea leaves falling onto the second conveying surface 220 and further increases the cooling blowing time of the first fan assembly 300 on the tea leaves, thereby further improving the cooling efficiency.

[0028] Example 3: like Figure 1 , Figure 2 As shown, this application embodiment provides a cooling device for a tea cooling conveyor. In addition to the above-mentioned technical features, the frame 100 further includes: The first baffle 110 is placed on the frame 100 and corresponds to the first conveying surface 210; The second baffle 120 includes an observation window 130, which is movably mounted on the second baffle 120. The second baffle 120 and the observation window 130 have a mesh structure.

[0029] The first baffle 110 is installed on the frame 100 by bolts and other fasteners. When tea leaves are placed on the first conveying surface 210 for conveying, the first baffle 110 restricts the tea leaves from falling from both sides of the first conveying surface 210, improving the stability of the tea leaves during conveying. The second baffle 120 is installed on the frame 100 by bolts and other fasteners. The second baffle 120 corresponds to both sides of the guide plate 330. The second baffle 120 is used to prevent tea leaves from falling outside the conveyor belt 200 when they fall from the first conveying surface 210 to the second conveying surface 220. The observation window 130 is installed on the second baffle 120 by a hinge, which can be opened to observe the internal working conditions. Through the web structure, when a small amount of airflow flows to both sides under the action of the guide plate 330, the web structure allows the airflow to pass through, reducing the turbulence of the airflow inside, making the tea leaves more stable during the falling process, and ensuring the uniformity of leaf distribution.

[0030] Furthermore, the rack 100 also includes: The first collection box 140 is located below the first conveying surface 210; The first guide surface 150 is located below the first conveying surface 210 and is connected to the first collection box 140; The second collection box 160 is located below the second conveying surface 220; The second guide surface 170 is located below the second conveying surface 220 and is connected to the second collection box 160.

[0031] During the movement of tea leaves, some smaller fragments and impurities fall through the first mesh belt. Some of the fragments and impurities falling on the first conveyor surface 210 fall directly into the first collection box 140, while others first fall onto the first guide surface 150 and then slide into the first collection box 140. Some of the fragments and impurities falling on the second conveyor surface 220 fall directly into the second collection box 160, while others first fall onto the second guide surface 170 and then slide into the second collection box 160. The first collection box 140 and the second collection box 160 are used to collect the fragments and impurities, improving the cleanliness of the working environment.

[0032] Example 4: like Figure 2 As shown, this application embodiment provides a cooling device for a tea cooling conveyor. In addition to the above-mentioned technical features, the partition structure 410 further includes: The housing 411 is mounted on the frame 100, and one end of the housing 411 is connected to the second fan assembly 400. Partition 412 is installed in housing 411; End plate 413 is installed at one end of housing 411 and away from the second fan assembly 400.

[0033] The housing 411 is installed on the frame 100 by bolts and other fasteners. The partition 412 is installed in the housing 411. The air volume blown out from the air outlet 312 of the second fan assembly 400 is divided into several parts by the partition 412. The partition 412 directs the blown air so that it can act on the conveyor belt 200. The partition 412 divides the air volume from the air outlet 312 of the second fan assembly 400 into a longer range to act on the conveyor belt 200, thereby increasing the cooling range. The end plate 413 is installed on the housing 411. The end plate 413 and the second fan assembly 400 are respectively placed at both ends of the housing 411. The end plate 413 ensures that all the air volume acts on the second conveyor surface 220.

[0034] Example 5: like Figure 3 , Figure 4 As shown, this application embodiment provides a cooling device for a tea cooling conveyor. In addition to the above-mentioned technical features, the partition structure 410 further includes: The first slide rail 600 is installed on the inner side wall of the housing 411; The first slide block 610 is installed and connected to the partition plate 412 and slidably connected to the first slide rail 600; The second slide rail 620 is installed inside the housing 411; The second slide block 630 and the second slide rail 620 are slidably connected; The third slide 640 is hinged to the second slide 630; The third slide rail 650 is installed on the partition 412; A connector 660 is hinged between two partitions 412. The connector 660 is respectively hinged to the second slide 630 of the left partition 412 and the first slide 610 of the right partition 412. The drive cylinder 670 is installed between the two ends of the second slide rail 620 and the housing 411.

[0035] The first slide rail 600 is slidably connected to the first slide block 610, allowing the partition 412 to move along the axis of the first slide rail 600. The second slide rail 620 is slidably connected to the second slide block 630, and the third slide block 640 is movably connected to the third slide rail 650. The first slide rail 600 is mounted on the inner wall of the housing 411 by fasteners, the third slide rail 650 is mounted to the partition 412 by fasteners, and the second slide block 630 and the third slide block 640 are hinged together by a shaft. However, the partitions 412 are arranged in parallel, with the first slide block 610 on one end of the partition 412 fixedly connected to the first slide rail 600. The drive cylinder 670 is hydraulically, pneumatically, or electrically driven and controlled, controlling the movement of the second slide rail 620. The drive cylinder 670 is connected between the two ends of the second slide rail 620 and the two ends of the first slide rail 600. Each partition 412 is connected by a connector 660. The connector 660 is connected to the partition. The hinges between the second slide rail 620 and the first slide rail 600 allow for two states between them. One state is that the axes of the second slide rail 620 and the first slide rail 600 are parallel, and the spacing between each partition 412 is the same. However, when air blows out from the air outlet 312, the airflow intensity corresponding to the partition 412 farther from the air outlet 312 is lower. This means that the airflow intensity gradually increases during the movement of the tea leaves. This is suitable when the average tea leaf conveying amount is greater than or equal to the set value L, as it slowly increases the airflow intensity to prevent more tea leaves from stacking during cooling. The other state is that the axes of the second slide rail 620 and the first slide rail 600 have a certain angle. In this state, the spacing between each partition 412 is different, and the spacing between the partitions 412 farther away from the second fan assembly 400 is smaller. This allows the airflow to be applied more evenly to the second conveying surface 220 through the partitions 412. This is suitable when the average tea leaf conveying amount is less than the set value L.

[0036] Example 6: This application also provides a cooling method for a cooling device of a tea cooling conveyor, the specific steps of which include: S1, place the tea leaves that need to be cooled at the lower end of the first conveying surface 210, lift them up by the conveyor belt 200 and drop them from the upper end of the first conveying surface 210 onto the second conveying surface 220, and blow and cool the tea leaves by the first fan assembly 300 during the falling process; S2, the tea leaves falling onto the second conveyor surface 220 are lifted by the conveyor belt 200 and passed through the partition structure 410, and the tea leaves on the second conveyor surface 220 are cooled by the second fan assembly 400 and the partition structure 410. S3, the tea leaves continue to rise on the second conveyor surface 220, fall at the upper end of the second conveyor surface 220, and fall through the discharge port 500.

[0037] The tea leaves are evenly dispersed and efficiently cooled as they fall from the first conveyor surface 210 to the second conveyor surface 220. The cooling continues on the second conveyor surface 220, giving the tea leaves a high cooling efficiency. At the same time, dispersing the leaves and cooling are combined on the same frame 100, further improving the cooling efficiency.
