Description

Technical Field

[0001] The present application relates to the technical field of black tea processing, and in particular to a withering device for black tea processing. Background Art

[0002] Black tea is the young leaves or buds of the tea plant of the family Theaceae. Black tea is not grown naturally, but was made on the basis of green tea in the late Ming and early Qing dynasties. It is made from suitable new tea leaves of tea trees, and is refined through a series of processes such as withering, rolling (cutting), fermentation, and drying. Withering is an important step in the tea manufacturing process. The purpose of withering is to make the tea leaves gradually lose moisture, causing the chemical composition inside the tea leaves to change, preparing for subsequent fermentation, rolling, and baking steps. Withering makes the tea leaves gradually soften, and the cells on the edge of the tea leaves will be damaged, causing the substances inside the tea leaves to come into contact with oxygen. This not only helps oxidation, but also makes it easier to roll the tea leaves into the desired shape, such as curling the tea leaves into a ball or flat.

[0003] The utility model with announcement number CN218278568U discloses a withering device for black tea processing, comprising a mounting frame, a closed cover plate movably mounted on the top of the mounting frame, a heating mechanism mounted in the middle of the bottom of the mounting frame, a placement plate mounted in the middle of the inner cavity of the mounting frame, and evenly distributed air guide holes are vertically opened inside the placement plate, air guide frames are mounted on the left and right inner walls of the mounting frame, air guide pipes arranged at equal distances are commonly mounted on opposite sides of the two air guide frames, and nozzles arranged at equal distances in the horizontal direction are mounted on the top of the air guide pipes, support frames are mounted on the left and right inner walls of the mounting frame, a driving rod is commonly mounted laterally inside the two support frames, and evenly distributed adjusting paddles are mounted on the outer side of the driving rod, a locking frame is mounted on the top of the left side of the mounting frame, and a connecting block is mounted on the left side of the closed cover plate, and the connecting block is connected to the locking frame; the utility model facilitates turning the tea leaves by adjusting the paddles during the withering process of the tea leaves, thereby improving the effect and efficiency of withering the tea leaves.

[0004] The above scheme mainly drives the adjusting paddle to rotate by the rotation of the driving rod, thereby realizing the flipping of the tea leaves on the placement plate, so that the tea leaves can be heated more evenly. However, when the adjusting paddle stirs the tea leaves due to the rotation of the driving rod, some tea leaves will be piled up in a corner of the placement plate due to the pushing and stirring of the adjusting paddle, so that the piled tea leaves will still be heated unevenly, or cannot be dried after heating, thereby reducing the yield of tea leaves when withering. Therefore, those skilled in the art provide a withering device for black tea processing to solve the problems raised in the above background technology. Utility Model Content

[0025] The following is combined with Figure 1-6 This application is described in further detail.

[0026] The present application embodiment discloses a withering device for black tea processing. Figure 1-6 A withering device for black tea processing comprises a box body 1, a hinge door panel 2, a connecting block 31 and a vibration mechanism 4. The hinge door panel 2 is hinged to one side of the box body 1 through a hinge. A placing rack 8 is arranged inside the box body 1. A placing box 9 is arranged on the upper side of the placing rack 8. The placing box 9 is hinged to a cover plate 10 through a hinge. An inclined block 13 is fixedly connected to the inside of the placing box 9. A connecting block 31 is fixedly arranged inside the box body 1. A heating plate 33 is fixedly connected to the inside of the connecting block 31. An air outlet pipe 32 is fixedly connected to the lower side of the connecting block 31, and a plurality of air outlet pipes 32 are arranged. An air inlet pipe 35 is fixedly connected to the upper side of the connecting block 31. The air inlet pipe 35 runs through the box body 1. An air pump 34 is arranged on the outer side of the air inlet pipe 35. The vibration mechanism 4 is arranged on the lower side of the cover plate 10. The cover plate 10 is used to increase the uniformity of heating of tea leaves.

[0027] In this way, during the implementation process, when the tea leaves need to be withered, the staff can smoothly place the tea leaves inside the placement box 9, and through the connection between the cover plate 10 and the placement box 9, flip the cover plate 10 to the upper side of the placement box 9 to close the placement box 9, so that the tea leaves are not easy to spill out from the inside of the placement box 9 when withering, and the placement rack 8 can play the role of placing and bearing the placement box 9, thereby increasing the stability of the placement box 9 when in use and placed, and allowing the tea leaves to wither smoothly. The connecting block 31 can play the role of installing and connecting the air outlet pipe 32, the heating plate 33, the air pump 34 and the air inlet pipe 35, and the connecting block 31 is connected to the air outlet pipe 32 and the air inlet pipe 35;

[0028] When the staff needs to add hot air to the inside of the box body 1, the vacuum pump 34 can smoothly extract the external air through its own operation and draw it into the inside of the connecting block 31, and the heating plate 33 can heat the air drawn into the inside of the connecting block 31, so that the air flowing out through the air outlet pipe 32 can maintain a high temperature, and then the high-temperature air can smoothly flow into the inside of the placement box 9 to achieve the withering of the tea leaves. At the same time, there are multiple air outlet pipes 32, which can greatly increase the air outlet volume of the connecting block 31, thereby improving the efficiency of the tea leaves when withering. The heating plate 33 is similar to the principle of the existing electric heating resistance wire when in use, so the specific working principle is not repeated here.

[0029] The vibration mechanism 4 can drive the placement rack 8 and the placement box 9 to move up and down, thereby realizing the vibration of the placement box 9 and the tea leaves inside the placement box 9, so that the tea leaves inside the placement box 9 can be smoothly turned over, turned over and shaken by vibration when withering, thereby increasing the area that the tea leaves can contact when being dried by hot air. At the same time, the inclined block 13 can guide the tea leaves inside the placement box 9 through its own inclined surface, so that the tea leaves can slide smoothly to the middle part of the inclined block 13 through its own weight and the vibration of the placement box 9, so that the tea leaves are not easily accumulated in the corners, and the efficiency of the tea leaves when being withered can be further increased.

[0030] Among them, the vibration mechanism 4 includes a spring 41 and a fixed rod 42 fixedly connected to the lower side of the placement box 9, the spring 41 is arranged on the outer side of the fixed rod 42, the lower side of the fixed rod 42 is rotatably connected with a rotating rod block 44, the interior of the box body 1 is fixedly connected with a limit block 43, the fixed rod 42 is slidably connected to the inside of the limit block 43, one side of the box body 1 is fixedly connected with a connecting plate 45, the upper side of the connecting plate 45 is fixedly connected with a servo motor 46, the output shaft of the servo motor 46 passes through the box body 1, the output shaft of the servo motor 46 is fixedly connected with a cam 47 through a coupling, and the cam 47 is arranged on the outer side of the rotating rod block 44, and the placement frame 8 can play a role in arranging the spring 41 and the fixed rod 42 The box body 1 can be connected to the limit block 43, and the limit block 43 can cooperate with the placement frame 8 to fix the fixing rod 42, so that the fixing rod 42 can be smoothly extended and retracted when in use. At the same time, when the placement frame 8 moves downward, the fixing rod 42 will be squeezed, and the fixing rod 42 can elastically reset the placement frame 8 through its own elasticity. At the same time, the limit block 43 can limit the placement frame 8 through the spring 41, so that when the placement frame 8 vibrates up and down, it is not easy to tilt, shake or fall down, which increases the stability of the placement frame 8 during vibration. The limit block 43 can also be connected to the rotating rod block 44;

[0031] The box body 1 can also install and fix the servo motor 46 through the connecting plate 45. The servo motor 46 can not only connect to the cam 47, but also drive the cam 47 to rotate through its own operation. When the cam 47 rotates, it will smoothly push the rotating rod block 44. When the cam 47 rotates half a circle, it will push the rotating rod block 44. At this time, the rotating rod block 44 will be connected to the placement rack 8 through the spring 41, driving the placement rack 8 and the placement box 9 to move upward. After the cam 47 continues to rotate half a circle, the push on the rotating rod block 44 will be cancelled. At this time, the placement rack 8 and the placement box 9 can be reset by their own weight and the elasticity of the spring 41. The long-term reciprocating cycle will smoothly realize the up and down vibration of the placement rack 8 and the placement box 9.

[0032] Preferably, one side of the cover plate 10 and the placement box 9 are fixedly connected with a fixing block 11, the internal threads of the two fixing blocks 11 are connected with a second bolt 12, both sides of the placement box 9 are fixedly connected with a connecting block 5, and the upper side of the placement frame 8 is provided with a first screw rod 6 and a limiting rod 7, one of the connecting blocks 5 is threadedly connected to the outer side of the first screw rod 6, and the other connecting block 5 is slidably connected to the outer side of the limiting rod 7, the cover plate 10 and the placement box 9 can both install and fix the fixing block 11, and the second bolt 12 will effectively connect the two fixing blocks 11, so that the cover plate 10 can close the placement box 9 while the connection between itself and the placement box 9 is sufficiently stable, and it is not easy to flip over due to the up and down vibration of the placement box 9, thereby increasing the stability of the cover plate 10 when in use;

[0033] The placement box 9 can also fix and install the two connecting blocks 5. The first screw 6 and the placement frame 8 are rotatably connected, while the limiting rod 7 and the placement frame 8 are fixedly connected, which enables the limiting rod 7 to smoothly limit the placement box 9 through one of the connecting blocks 5. At the same time, when the first screw 6 rotates, it can drive the placement box 9 to move to one side of the placement frame 8 through the connection relationship between itself and the other connecting block 5, so that the placement box 9 can be firmly connected to the upper side of the placement frame 8, and it is not easy to fall from the upper side of the placement frame 8 due to the up and down vibration of the placement frame 8, thereby increasing the stability of the placement box 9 when in use.

[0034] Specifically, in this embodiment, a fixing plate 14 is fixedly connected inside the box body 1, and a sponge pad 15 is fixedly connected to the upper side of the fixing plate 14, and the sponge pad 15 is arranged on the lower side of the placement rack 8. The box body 1 can install and fix the sponge pad 15 through the fixing plate 14, and the setting of the fixing plate 14 makes it difficult for the placement rack 8 to slide down too far due to excessive speed when it is reset downward due to its own weight and the elasticity of the spring 41, and the sponge pad 15 can reduce the collision force between the lower side of the placement rack 8 and the upper side of the fixing plate 14, reducing the possibility of damage to the placement rack 8 and the fixing plate 14 due to collision.

[0035] More specifically, a mounting groove 18 is provided on one side of the hinge door panel 2, and the mounting groove 18 is communicated with the interior of the box body 1. The hinge door panel 2 is located inside the mounting groove 18 and is fixedly connected with a temperature display 19. The hinge door panel 2 can install and fix the temperature display 19 through the mounting groove 18, and the temperature display 19 can detect and display the temperature inside the box body 1, thereby facilitating the staff to observe the temperature inside the box body 1, so that when the temperature inside the box body 1 is too high or too low, the staff can discover it in time.

[0036] Furthermore, in the present embodiment, universal wheels 17 are fixedly connected to the four corners of the lower side of the box body 1, and a protective sponge layer 16 is fixedly connected to the outer side of the cam 47. The provision of the universal wheels 17 can facilitate the staff to push the box body 1, so that the box body 1 can be moved easily when it needs to be moved, and the protective sponge layer 16 can reduce the collision force between the cam 47 and the rotating rod block 44, thereby reducing the possibility of damage between the cam 47 and the rotating rod block 44 due to collision and pushing, and increasing the service life of the cam 47 and the rotating rod block 44.

[0037] The implementation principle of a withering device for black tea processing in an embodiment of the present application is as follows: when in use, the staff can place the tea leaves that need to be withered into the inside of the placement box 9, and place the placement box 9 on the upper side of the placement rack 8. When placing, the first screw 6 can be rotated so that the first screw 6 limits one of the connecting blocks 5 through the limiting rod 7, thereby driving the placement box 9 to move smoothly to one side of the placement rack 8, and after contacting the placement rack 8, the connection can be sufficiently stable. After that, the staff can connect the two fixing blocks 11 through the second bolt 12, thereby reducing the possibility of the cover plate 10 flipping over during use. After that, the staff can start the vacuum pump 34, the heating plate 33 and the servo motor 46, and at the same time close and close the box body 1 through the hinge door panel 2.

[0038] When in use, the vacuum pump 34 can smoothly extract external air through its own operation and draw it into the interior of the connecting block 31, and the heating plate 33 can heat the air drawn into the interior of the connecting block 31, so that the air flowing out through the outlet pipe 32 can maintain a high temperature, and then the high-temperature air can smoothly flow into the interior of the placement box 9.

[0039] The operation of the servo motor 46 will smoothly drive the cam 47 to rotate, and when the cam 47 rotates half a circle, it will push the rotating rod block 44. At this time, the rotating rod block 44 will be connected to the placement rack 8 through the spring 41, driving the placement rack 8 and the placement box 9 to move upward. After the cam 47 continues to rotate half a circle, the push on the rotating rod block 44 will be cancelled. At this time, the placement rack 8 and the placement box 9 can be reset by their own weight and the elasticity of the spring 41. The long-term reciprocating cycle will be able to smoothly realize the up and down vibration of the placement rack 8 and the placement box 9, thereby driving the flipping and vibration of the tea leaves through the up and down vibration of the placement box 9, and the blowing of hot air by the exhaust pipe 32, thereby realizing the withering of the tea leaves and increasing the withering yield rate.
