[0002] Withering is a key step in the tea production process. It is an important process in tea making, used to reduce the moisture content of tea leaves and promote the formation of tea aroma and taste. The main purpose of the withering machine is to help the tea leaves lose a certain amount of moisture by controlling temperature, humidity and airflow, making them soft, which is helpful for subsequent rolling, fermentation and other processes.

[0003] When withering tea leaves in an existing withering machine, a layer of gauze is first laid on the mesh plate of the withering machine, and tea leaves are placed on the gauze, and the tea leaves are withered by hot air from bottom to top. During the withering process, workers are required to manually turn the tea leaves over to ensure that the tea leaves are heated evenly, and at the same time observe the shape of the tea leaves with the naked eye to determine whether the tea leaves have been withered. The manual processing method is affected by subjective factors, which can easily lead to inaccurate judgments, resulting in different withering effects of different batches of tea leaves, affecting the stability of the tea quality. In view of this, the utility model proposes a withering machine. Utility Model Content

[0031] Example

[0032] like Figure 1 and Figure 2 As shown, a withering machine proposed in the utility model includes a withering trough 1, in which a first mesh plate 2 is fixedly arranged, a second mesh plate 3 is arranged above the first mesh plate 2, and multiple groups of holes are provided on the first mesh plate 2 and the second mesh plate 3 to facilitate the flow of hot air. At the same time, the first mesh plate 2 is used to disperse the hot air, so that the hot air passing through the second mesh plate 3 is more uniform, so that the tea leaves are evenly heated. The second mesh plate 3 is fixedly connected to the inner wall of the withering trough 1, and gauze is laid on the second mesh plate 3, and tea leaves are placed in the gauze for withering. A thermometer is installed in the withering trough 1 to detect the temperature in real time, and at the same time, the power of the electric heating tube 44 is adjusted to maintain a constant temperature of the hot air. Four groups of supporting legs 11 are provided at the bottom of the withering trough 1, and weighing units 12 are installed on the sides of the supporting legs 11. The four groups of weighing units 12 are respectively located at the four corners of the bottom of the withering trough 1. The weighing units 12 are used to weigh the overall weight of the withering trough 1. At the same time, after the tea leaves are placed on the second mesh plate 3, the initial weight of the tea leaves can be recorded, and when the tea leaves lose 30% of their weight, it is known that the withering operation has been completed.

[0033] Furthermore, the withering machine further comprises a plurality of hot air pushing mechanisms 4 arranged on one side of the withering trough 1, and the hot air pushing mechanisms 4 are used to blow hot air into the withering trough 1. The hot air pushing mechanisms 4 comprise a cylinder 41 arranged on one side of the withering trough 1, the cylinder 41 being fixed on a frame, and an air duct 42 being provided in the cylinder 41, and the air duct 42 being provided to facilitate the circulation of air. The air duct 42 is connected to the interior of the withering trough 1, and the air duct 42 is located below the first mesh plate 2, so that the air entering the withering trough 1 through the air duct 42 is first located below the first mesh plate 2, so that the first mesh plate 2 can disperse the air. A protective net 43 is installed at one end of the air duct 42 away from the withering trough 1 for protection. A plurality of electric heating tubes 44 are installed in the air duct 42, and the plurality of electric heating tubes 44 are distributed in a ring array, and the electric heating tubes 44 are used to heat the air when it passes through, so that the temperature of the air entering the withering trough 1 is relatively high, which is convenient for withering the tea leaves. A fan 45 is provided on one side of the electric heating tube 44 close to the withering trough 1 . The fan 45 is installed in the air duct 42 . When the fan 45 is started, the air flows.

[0034] For further information, see Figure 3 The above-mentioned withering machine includes a tea turning assembly 5 arranged above the second mesh plate 3, and the tea turning assembly 5 is used to turn the tea leaves. The tea turning assembly 5 includes a first slide rail 51 arranged above the withering trough 1, and a first slider 52 is slidably connected to the first slide rail 51, and a mounting plate 53 is fixedly connected to the top of the first slider 52. The mounting plate 53 moves synchronously with the first slider 52, and moves smoothly due to the limiting effect of the first slide rail 51. A servo motor 54 is installed on the top of the mounting plate 53, and the output end of the servo motor 54 passes through the mounting plate 53 and is fixedly connected to a connecting rod 55. After the servo motor 54 is started, it drives the connecting rod 55 to rotate. The end of the connecting rod 55 away from the servo motor 54 is fixedly connected to a mounting frame 56, and a plurality of tea turning blocks 57 are installed at the bottom of the mounting frame 56. When the connecting rod 55 rotates, it drives the mounting frame 56 and the tea turning blocks 57 to rotate synchronously. The tea turning block 57 is arranged in a "human" shape, so that the tea turning block 57 can turn the tea leaves at the bottom to the top when it rotates, so as to achieve uniform heating of the tea leaves and improve the consistency of the tea leaves during withering. A gear 58 is installed on the outer ring of the connecting rod 55, and the connecting rod 55 drives the gear 58 to rotate synchronously when it rotates. A rack 59 is arranged on the side of the gear 58 away from the first slider 52, and the gear 58 meshes with the rack 59. When the gear 58 rotates, it moves along the length direction of the rack 59, and at the same time drives the mounting plate 53 and the first slider 52 to move synchronously, so as to drive the tea turning block 57 to move on the withering tank 1 to turn the tea leaves at different positions.

[0035] Finally, the above-mentioned withering machine also includes a moving mechanism 6 installed on the withering trough 1, and the moving mechanism 6 is used to adjust the position of the tea turning assembly 5 to turn the tea leaves evenly. The moving mechanism 6 includes two groups of linear motors 61 installed on the side of the withering trough 1 through a frame, and the two groups of linear motors 61 are symmetrically arranged on both sides of the withering trough 1. The moving ends of the linear motors 61 are fixedly connected to the limit rods 62, and the tops of the two groups of limit rods 62 are commonly fixedly connected with a top plate 63. The two groups of linear motors 61 keep synchronous movement through the controller, and the two groups of linear motors 61 drive the two groups of limit rods 62 and the top plate 63 to move synchronously. The two groups of top plates 63 are slidably connected to the limit blocks 64, and the first slide rail 51 and the rack 59 are fixedly connected between the two groups of limit blocks 64, so that the linear motor 61 can drive the first slide rail 51 and the rack 59 to move after starting, thereby adjusting the position of the tea turning block 57. A second slide rail 65 is installed at the bottom of the top plate 63, and a second slider 66 is slidably connected to the second slide rail 65. A fixed plate 67 is fixedly connected to the bottom of the second slider 66. The fixed plate 67 is L-shaped. A push rod motor 68 is installed on one side of the fixed plate 67. The second slide rail 65 and the second slider 66 make the push rod motor 68 move smoothly. The output end of the push rod motor 68 is fixedly connected to the mounting plate 53. The mounting plate 53 drives the push rod motor 68 to move synchronously when moving, and the push rod motor 68 can adjust the distance between the tea turning block 57 and the second mesh plate 3 after starting, so as to facilitate turning the tea leaves. At the same time, it is convenient to remove the tea turning block 57 from the withering tank 1, and it is convenient for workers to load and unload the tea leaves after removing them.

[0036] In this embodiment, first, the gauze is laid on the second mesh plate 3, and then the tea leaves are evenly laid on the gauze on the second mesh plate 3. At this time, the multiple groups of weighing units 12 record the weight of the tea leaves. Then, the electric heating tube 44 and the fan 45 are started, and the fan 45 drives the outside air into the withering tank 1. At the same time, the air is heated when passing through the electric heating tube 44. The hot air entering the withering tank 1 is dispersed by the first mesh plate 2 and blown to the second mesh plate 3. The thermometer in the withering tank 1 checks the temperature and automatically adjusts the power of the electric heating tube 44 so that the temperature is maintained at a suitable level. At this time, the hot air is evenly blown to the tea leaves to wither the tea leaves. At the same time, the linear motor 61 is started to drive the tea turning block 57 to move to the top of the withering tank 1. At this time, the push rod motor 68 extends and drives the mounting plate 53 to move downward. At this time, the tea turning assembly 5 moves downward as a whole, and moves smoothly under the limiting action of the limiting rod 62 and the limiting block 64, so that the tea turning block 57 is close to the bottom of the tea leaves. At this time, the servo motor 54 starts to drive the connecting rod 55 to rotate slowly. At this time, the tea turning block 57 rotates to slowly turn the tea leaves to prevent the tea leaves from breaking. Since the gear 58 is meshed with the rack 59, the gear 58 can also move along the length direction of the rack 59 when rotating. At this time, the mounting plate 53 drives the first slider 52 to slide on the first slide rail 51, and the push rod motor 68 moves synchronously under the limiting action of the second slide rail 65 and the second slider 66, and cooperates with the linear motor 61 to adjust the position, so that all the tea leaves can be turned evenly to ensure that the tea leaves are heated evenly. Finally, when the weight detected by the weighing unit 12 is reduced by 30%, the withering is completed, the electric heating tube 44 and the fan 45 stop working, and the tea turning component 5 and the moving mechanism 6 are reset, and the tea turning component 5 is moved away from the withering tank 1 to facilitate the workers to take out the tea leaves.

[0037] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
