This solves problems such as uneven heating, insufficient aroma, and poor appearance inherent in traditional single drying or frying processes, thus improving the stability of green tea quality and production efficiency. By combining the gentle dehydration of drying with the high-temperature aroma enhancement of frying, it preserves the fresh and tender internal qualities of the tea leaves, reduces nutrient loss, and lowers labor costs through standardized mechanized operations, adapting to the needs of large-scale production.

[0003] A new type of green tea production equipment combines roasting and frying, integrating multiple processes such as fixation, rolling, and drying. This solves problems such as uneven heating, insufficient aroma, and poor appearance that exist in traditional single drying or frying processes, improving the quality stability and production efficiency of green tea. By combining the gentle dehydration of drying with the high-temperature aroma enhancement of frying, it can preserve the tender internal qualities of tea leaves, reduce nutrient loss, and reduce labor costs through mechanized and standardized operations, adapting to the needs of large-scale production.

[0004] In existing technologies, some production equipment that combines roasting and frying of green tea generally only involves placing the green tea inside the equipment for steaming. When the tea leaves are piled up inside the equipment, the bottom layer of tea leaves are easily overheated and scorched because they are in direct contact with the heat source and have poor air permeability; while the top layer of tea leaves may turn yellow due to insufficient heat conduction and lose the bright green color that green tea should have. Therefore, a production equipment that combines roasting and frying of green tea is proposed to solve the above problems. Utility Model Content

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the green tea to be processed is placed inside the pot body, and then the flip cover is rotated to fit the pot body, thereby simmering the tea inside the pot body. After simmering, motor one is started, and motor one drives the guide teeth to slide inside the sliding groove, so that the outside of the moving column slides inside the flip cover.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a production equipment for green tea production that combines roasting and frying. The equipment includes a shell 1, with a drying chamber 2 fixedly connected to the outside of the shell 1. The drying chamber 2 can generate hot air through a heating device for drying the tea leaves. A pot 3 is fixedly connected to the top of the shell 1. The pot 3 is the main container for the tea leaves to be steamed and shaken. A fixing plate 4 is fixedly connected to the top of the pot 3. The fixing plate 4 is used to install a motor 5. The motor 5 provides power for the oscillation of the stirring blades 8. A guide tooth 6 is fixedly connected to the drive end of the motor 5. The guide tooth 6 cooperates with the sliding groove 10 inside the moving column 7 to form a transmission structure.

[0033] A flip cover 9 is rotatably connected to the top of the pot body 3. The flip cover 9 can be rotated and opened to seal the pot body 3 and unload the material. A moving column 7 is slidably connected inside the flip cover 9. The up and down sliding of the moving column 7 drives the stirring blade 8 to swing. The stirring blade 8 is fixedly connected to the outside of the moving column 7. The stirring blade 8 is used to turn the tea leaves and make them shake. A feeding plate 11 is rotatably connected to the bottom of the pot body 3. The feeding plate 11 can be rotated to open the bottom of the pot body 3, allowing the tea leaves to fall onto the conveyor belt 19. A conveying component is set inside the shell 1. The conveying component is used to transport the tea leaves and cooperate with the drying process. A sorting component is set inside the shell 1. The sorting component is used to remove impurities and dust from the tea leaves.

[0034] The movable column 7 has a sliding groove 10 inside, which provides a track for the sliding of the guide teeth 6. The guide teeth 6 are externally slidably connected to the inside of the movable column 7. The up and down movement of the movable column 7 is achieved by the relative sliding of the guide teeth 6 and the sliding groove 10. The conveying assembly includes a first conveyor belt 19, which is externally located inside the housing 1. The first conveyor belt 19 is used to receive and convey the tea leaves after shaking. The second conveyor belt 21 is provided inside the housing 1. The second conveyor belt 21 is used to convey the tea leaves from the inclined plate 20 to the feeding box 14. The second motor 22 is fixedly connected to the outside of the housing 1. The second motor 22 provides power for the operation of the first conveyor belt 19 and the second conveyor belt 21. The inclined plate 20 is fixedly connected inside the housing 1. The inclined plate 20 is used to guide the tea leaves from the first conveyor belt 19 to the second conveyor belt 21.

[0035] The processing personnel place the green tea to be processed into the pot body 3, and rotate the flip cover 9 to make it fit the pot body 3. The sealing fit between the flip cover 9 and the pot body 3 suffocates the tea leaves inside. The suffocation process can quickly deactivate the oxidizing enzymes in the tea leaves, preserving the color and nutrients of the tea leaves. After suffocation, the motor 5 is started. The drive end of the motor 5 drives the guide teeth 6 to slide in the sliding groove 10. The tooth shape of the guide teeth 6 and the inner wall of the sliding groove 10 form a meshing transmission, which drives the moving column 7 to slide up and down vertically in the flip cover 9. The sliding of the moving column 7 causes the stirring blade 8 to swing back and forth when turning the tea leaves. The swing trajectory of the stirring blade 8 creates a shaking effect in the pot body 3. This shaking can accelerate the evaporation of water vapor in the tea leaves, promote the dissipation of water vapor in the fresh leaves, and at the same time, the contact friction between the stirring blade 8 and the tea leaves raises the leaf temperature. The uniform leaf temperature distribution avoids quality problems caused by local overheating, such as red stems and red leaves.

[0036] Reference Figure 1 , Figure 2 and Figure 4 The sorting assembly includes a positioning column 12, which provides rotational support for the feeding box 14 and the screen 13. The external part of the positioning column 12 is rotatably connected to the inside of the housing 1. The external part of the positioning column 12 is fixedly connected to the feeding box 14, which is used to carry tea leaves and perform sieving. The bottom end of the feeding box 14 is fixedly connected to the screen 13, which is used to separate impurities and dust from the tea leaves. The external part of the conveyor belt 19 is fixedly connected to a rotating column 15, which rotates synchronously with the drive roller of the conveyor belt 19. The external part of the rotating column 15 is fixedly connected to a rotating block 16, which is used to drive the rotating rod 17 to swing.

[0037] A rotating rod 17 is rotatably connected to the outside of the housing 1. The fan-shaped rotation of the rotating rod 17 drives the material box 14 to swing through the transmission rod 18. The top of the material box 14 is rotatably connected to the transmission rod 18, which transmits the swinging power of the rotating rod 17. A sliding groove is provided inside the rotating rod 17 to provide space for the sliding of the rotating block 16. The outside of the rotating block 16 is slidably connected to the inside of the sliding groove. The sliding of the rotating block 16 in the sliding groove forms a crank-slider motion. A sliding groove is provided at the front end of the housing 1 to provide guidance for the sliding of the transmission rod 18. The outside of the transmission rod 18 is slidably connected to the inside of the sliding groove. A slot is provided inside the rotating rod 17 to provide a track for the sliding of the transmission rod 18. The outside of the transmission rod 18 is slidably connected to the inside of the slot. The outside of the material box 14 is slidably connected to the inside of the housing 1. The material box 14 can swing back and forth along the track inside the housing 1. The rotating rods 17 are symmetrically distributed at the front end of the housing 1. The symmetrical distribution of the rotating rods 17 makes the swinging of the material box 14 more stable.

[0038] After the initial shaking is complete, the feeding plate 11 rotates and opens, allowing the tea leaves to fall onto the first conveyor belt 19. The rotation of the first conveyor belt 19 transports the tea leaves to the drying area. The drying chamber 2 supplies hot air into the shell 1, and the hot air is evenly distributed through the air ducts inside the shell 1 to dry the tea leaves. The tea leaves move along the first conveyor belt 19 to the inclined plate 20, and under the action of gravity, they slide down the inclined plate 20 to the second conveyor belt 21. The second conveyor belt 21 continues to carry the tea leaves to the top of the feeding box 14. Motor 22 drives the transmission rollers of transmission belt 19 and transmission belt 21 to rotate inside the housing 1 through a transmission system consisting of a transmission belt and pulley, realizing continuous conveying of tea leaves. The rotating roller at the front end of transmission belt 21 drives the rotating column 15 to rotate. The rotation of the rotating column 15 causes the rotating block 16 to slide in the groove inside the rotating rod 17. The sliding of the rotating block 16 pushes the rotating rod 17 to rotate in a fan shape outside the housing 1. The fan-shaped rotation of the rotating rod 17 pulls the feeding box 14 and the screen 13 through the transmission rod 18, causing them to swing back and forth inside the housing 1 through the positioning column 12. The back and forth swing of the feeding box 14 and the screen 13 makes the tea leaves continuously loosen during the sieving process, improving the sieving effect. Tea leaves fall from the front end of the feeding box 14 as it swings. The holes in the feeding box 14 are designed according to the size of the tea leaves to intercept impurities and dust. Impurities and dust are removed after the tea leaves are processed. The processed tea leaves that meet the specifications will be discharged from the front end of the feeding box 14. Impurities and dust that are larger than the holes will be discharged from one side of the screen 13. This integrated screening design ensures the quality of the tea leaves while eliminating the need for subsequent removal operations, reducing manual intervention and improving work efficiency.

[0039] Working principle: When processing green tea, the tea to be processed is placed inside the pot body 3. Then, by rotating the flip cover 9, the flip cover 9 is made to fit against the pot body 3, thereby simmering the tea leaves inside the pot body 3. After simmering, the motor 5 is started. The motor 5 drives the guide teeth 6 to slide inside the sliding groove 10, thereby causing the outside of the moving column 7 to slide inside the flip cover 9. This causes the stirring blade 8 to swing back and forth up and down when it is turned inside the pot body 3, thus producing a shaking effect. This facilitates the dissipation of water vapor in the fresh leaves, which can increase the leaf temperature and prevent the formation of red stems and red leaves.

[0040] After the initial shaking process, the tea leaves will fall onto the top of conveyor belt 1919 as the feeding plate 1111 rotates. Simultaneously, the drying chamber 22 will steadily supply hot air into the housing 11 to dry the tea leaves inside. The tea leaves, carried by conveyor belt 1919, will fall onto the top of the inclined plate 2020, and then onto the top of conveyor belt 2121, until conveyor belt 2121 carries the tea leaves to the top of the feeding box 1414. At this point, motor 2222 will drive the transmission rollers of conveyor belt 1919 and conveyor belt 2121 to rotate inside the housing 11 via the transmission belt and pulley. The rotating roller at the front end of conveyor belt 2121... When rotating, the rotating column 1515 rotates inside the housing 11, causing the rotating block 1616 to slide inside the rotating rod 1717. This causes the rotating rod 1717 to rotate in a fan shape outside the housing 11, which in turn causes the transmission rod 1818 to pull the feeding box 1414 and the screen 1313 to swing back and forth inside the housing 11 via the positioning column 1212. The holes in the feeding box 1414 remove impurities and dust after tea processing. The processed tea leaves are discharged from the front end of the feeding box 1414, while impurities and dust are discharged from one side of the screen 1313, ensuring the quality of the tea leaves, eliminating the need for subsequent removal operations, and improving work efficiency.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
