Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea processing fixation machine. Background Technology

[0002] Fixing the green in tea leaves is a crucial step in the tea-making process. It is mainly used to destroy and deactivate the activity of oxidases in fresh leaves, inhibit the enzymatic oxidation of tea polyphenols, prevent the tea leaves from changing color (such as turning red or brown) during subsequent processing, remove the grassy smell, promote the formation of tea aroma, and also soften the tea leaves, making them easier to roll and shape later.

[0003] The process of fixing the leaves with green leaves can inhibit the activity of enzymes in the tea leaves. High temperatures will deactivate the polyphenol oxidase in the fresh leaves, thus preventing excessive oxidation of the tea leaves and maintaining the green characteristics of teas such as green tea. High temperatures also help to volatilize low-boiling-point aromatic substances, improve the aroma of the tea leaves, remove the grassy taste, and soften the leaves, making them easier to roll and shape later.

[0004] In existing technology, tea leaves are placed in a fixing machine, where the fixing process is achieved by heating the furnace and rotating the internal drum. However, there are some problems. The tea leaves are piled up in the drum. Although the drum is constantly turning, it cannot effectively disperse the clumps of tea leaves. Heat cannot penetrate the tea leaves well, resulting in undercooked tea leaves. In addition, there may be small particles or impurities in the tea leaves that cannot be effectively removed during the fixing process. Therefore, we urgently need a fixing machine for tea processing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art where the accumulation of tea leaves prevents heat penetration, and where the tea leaves are small or impurities cannot be effectively removed. Therefore, this invention proposes a tea processing fixation machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tea processing fixation machine includes a base plate and mounting frames symmetrically mounted on the base plate. A heating shell is provided between the two sets of mounting frames, and the heating shell is rotatably connected to the mounting frames via a round rod. The machine also includes a hydraulic cylinder fixedly mounted on the base plate. A connecting plate is rotatably connected to the bottom of the heating shell, and the output end of the hydraulic cylinder is rotatably connected to the connecting plate. When the hydraulic cylinder is working, the heating shell reciprocates around the axis of the round rod, and a roller is rotatably mounted inside the heating shell. A bracket is symmetrically mounted inside the roller, and a collection bucket is rotatably connected to the bracket via a bearing. The upper surface of the collection bucket has filter holes.

[0008] To make the drum rotate, preferably, a drive motor is fixedly installed on one end of the heating shell. The output end of the drive motor is fixedly connected to a first gear, and a second gear is fixedly connected to one open end of the drum. The first gear meshes with the second gear. When the drive motor starts, the first gear drives the second gear and the drum to rotate.

[0009] To limit the swing range of the roller, preferably, the included angle range of the heating shell swinging around the axis of the round rod is 0°-60°.

[0010] In order to allow the tea leaves to spread out better, preferably, the inner wall of the drum is fixedly connected with wave blades, and the number of wave blades is at least four sets, which are arranged in a circle at equal intervals on the inner wall of the drum. When the drum rotates, the tea leaves move along the extension direction of the wave blades.

[0011] In order to provide uniform heat inside the drum, preferably, the heating shell has a circular cavity, and a heating wire is fixedly installed inside the circular cavity, the heating wire being wound around the circular cavity along a spiral trajectory.

[0012] To prevent tea leaves from falling off when the drum rotates, preferably, inclined baffles are symmetrically installed on the inner walls of the drum at both open ends.

[0013] For collecting finer impurities, preferably, both ends of the collection bucket are provided with discharge ports, and baffle plates are inserted into the discharge ports.

[0014] Compared with the prior art, this utility model provides a tea processing fixation machine, which has the following beneficial effects:

[0015] 1. This tea processing fixing machine, through the setting of drive motor and hydraulic cylinder, when the output end of the drive motor drives, the first gear drives the second gear to rotate the drum. During the rotation, the tea leaves will tumble inside the drum in conjunction with the wave blades, so that the tea leaves can be heated better. When the output end of the hydraulic cylinder works, in conjunction with the support of the mounting frame, it repeatedly pushes out and retracts, so that the heating shell can swing back and forth. During the swing, the tea leaves will move along the inner wall of the drum, so that the tea leaves inside can also move axially during the circumferential motion, effectively reducing the accumulation of tea leaves and making the tea leaves heat evenly.

[0016] 2. This tea processing fixation machine, through the setting of a collection bucket and corrugated blades, allows the tea leaves to tumble inside the drum during rotation, ensuring better heating. Combined with the angle adjustment of the drum, the tea leaves can also move axially during their circular motion, effectively reducing tea leaf accumulation and ensuring even heating. As the tea leaves tumble upwards and fall downwards, they land on the filter holes in the collection bucket. Smaller tea leaves and impurities enter the collection bucket. When it is necessary to collect internal impurities, simply tilt the drum downwards via a hydraulic cylinder to collect the impurities and small tea leaves. This achieves the removal of smaller tea leaves and impurities during the fixation process.

[0017] The parts of this device not described herein are the same as or can be implemented using existing technology. This utility model reduces the accumulation of tea leaves in the drum, effectively ensures that the tea leaves are heated evenly during the fixation process, and can remove smaller tea leaves or impurities during the fixation process.

[0025] Example:

[0026] Reference Figures 1-4 A tea processing fixation machine includes a base plate 1 and mounting frames 2 symmetrically mounted on the base plate 1. A heating shell 3 is disposed between the two sets of mounting frames 2. A circular cavity 13 is formed inside the heating shell 3, and a heating wire 14 is fixedly installed within the circular cavity 13. The heating wire 14 is wound in a spiral trajectory within the circular cavity 13. Here, the heating wire 14 serves as a heating element to heat the heating shell 3, raising its internal temperature to the required temperature for tea fixation. The heating shell 3 is rotatably connected to the mounting frames 2 via round rods. Bearing holes are provided on the mounting frames 2. Both sides of the heating shell 3 are rotatably connected to bearings within the bearing holes on the mounting frames 2 via round rods. A temperature and humidity sensor is installed inside the heating shell 3 to detect temperature and humidity, facilitating temperature control by the operator. As a conventional technical solution, it will not be elaborated here. It also includes: a hydraulic cylinder 4 fixedly installed on the base plate 1, and a connecting plate 5 rotatably connected to the bottom of the heating shell 3 through a hinge seat. The output end of the hydraulic cylinder 4 is rotatably connected to the connecting plate 5. Here, when the output end of the hydraulic cylinder 4 works, it combines with the support of the mounting frame 2 and repeatedly pushes out and retracts, so that the heating shell 3 can swing back and forth. During the swinging process of the heating shell 3, the included angle range of the swinging of the heating shell 3 around the axis of the round rod is 0°-60°, and the swinging range is preferably 45°. Here, when the swinging working angle of the heating shell 3 reaches 60°, it is the discharge angle after the withering is completed, so that the accumulated tea leaves can move along the path. During the movement, the accumulated tea leaves can be dispersed, so that the tea leaves can be heated evenly and avoid the situation of undercooked tea leaves.

[0027] A drive motor 9 is fixedly mounted on the heating housing 3. A first gear 10 is fixedly connected to the output end of the drive motor 9. A second gear 11 is fixedly connected to one of the open ends of the drum 6, and the first gear 10 meshes with the second gear 11. When the drive motor 9 starts, the first gear 10 drives the second gear 11 and the drum 6 to rotate. The drum 6, rotatably mounted inside the heating housing 3, has symmetrically mounted brackets 7 inside it. A collection bucket 8 is rotatably connected to the brackets 7 via bearings. Here, when the drum 6 rotates, the collection bucket 8 does not rotate with the drum 6. Inclined baffles 15 are symmetrically mounted on the inner walls of the drum 6 at both open ends. The upper surface of the collection bucket 8... The drum 8 has a filter hole 16 and discharge ports 17 at both ends. A baffle plate 18 is inserted into the discharge port 17. Since the drum 8 remains stationary inside the drum 6, when the tea leaves turn upwards and fall onto the drum 8, the filter hole 16 on the drum 8 will collect the small tea leaves and impurities. The remaining tea leaves will slide down the surface of the drum 6 into the drum 6 for the urgent fixation process. When it is necessary to collect impurities, the hydraulic cylinder 4 can be used to raise one side of the drum 6, so that the drum 6 is tilted. Then the baffle plate 18 on the discharge port 17 can be opened to discharge the small tea leaves and impurities, which effectively improves the collection of small tea leaves and impurities.

[0028] The inner wall of the drum 6 is fixedly connected with wave blades 12. There are at least four sets of wave blades 12, which are arranged equidistantly in a circle on the inner wall of the drum 6. When the drum 6 rotates, the tea leaves move along the extension direction of the wave blades 12. At this point, when the output end of the drive motor 9 drives the first gear 10 to drive the second gear 11 to rotate the drum 6. During the rotation, the tea leaves will tumble inside the drum 6 in conjunction with the wave blades 12, so that the tea leaves can be heated better. Combined with the angle of the drum 6, the tea leaves inside can also move axially during the circumferential motion, which effectively reduces the accumulation of tea leaves and makes the tea leaves heat evenly.

[0029] In this invention, after the operator puts tea leaves into the drum 6 through any opening, the heating wire 14 heats the drum, raising the temperature inside the heating shell 3. This heats the first gear 10, which in turn drives the second gear 11 and the drum 6 to rotate. The tea leaves are tumbled inside the drum 6 by the wave blades 12. When the tea leaves reach a high point and fall downwards, they fall onto the collection bucket 8. Smaller tea leaves and impurities are collected through the filter holes 16. The remaining tea leaves slide down the surface of the collection bucket 8 back into the drum 6. The hydraulic cylinder 4 is then driven by the hydraulic cylinder 4, which, in conjunction with the safety mechanism... The support of the mounting frame 2 allows the roller 6 to swing slowly. During the swing, the tea leaves are separated along the path of the wave blades 12 and move from a high place to a low place under the action of gravity. Combined with the action of centrifugal force, the accumulated tea leaves are dispersed, making the tea leaves more evenly heated. After the withering is completed, the hydraulic cylinder 4 drives one side of the heating shell 3 to the maximum stroke, and the tea leaves are discharged. When it is necessary to collect impurities in the collection bucket 8, simply use the hydraulic cylinder 4 to tilt the roller 6 to the maximum angle and pull out the baffle plate 18 on the discharge port 17. The impurities and small tea leaves will fall downwards by gravity, thus realizing the collection process of small tea leaves or impurities.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
