Description

Technical Field

[0001] The present invention relates to the technical field of tea fermentation, and particularly relates to a tea fermentation processing device and a processing method. Background Art

[0002] Fermented tea is an important category in tea processing. According to the degree of fermentation, it can be divided into lightly fermented tea (such as white tea and yellow tea), semi-fermented tea (such as oolong tea), fully fermented tea (such as black tea), and post-fermented tea (such as dark tea and Pu-erh ripe tea).

[0003] Among them, some lightly fermented tea (yellow tea) needs to be stacked in a humid and hot environment for slight fermentation. Most semi-fermented tea, fully fermented tea, and post-fermented tea need to be spread out and stored at a specified temperature and humidity for a certain period of fermentation. During the fermentation process, it is necessary to turn over regularly to promote uniform fermentation of the tea until the color of different types of tea changes to the specified color and then the fermentation is terminated.

[0004] Currently, when fermenting tea, it is usually necessary to stack the tea layer by layer in a frame and then place it in a fermentation room, which results in low efficiency. It is also necessary to turn over the tea at intervals during the fermentation process to promote uniform fermentation of the tea. In addition, the tea is in a static state in the fermentation room and its position in the fermentation room does not change, so the fermentation progress and effect of the tea at different positions are different, and it is easy to cause over-fermentation or under-fermentation of the tea at different positions. Moreover, when turning over the tea, it is necessary to open the fermentation room, which is likely to allow bacteria, dust, etc. in the external environment to enter and affect the fermentation quality of the tea.

In addition, when spreading to the end, the baffle can reduce the discharging amount of tea leaves to ensure the evenness of tea leaf spreading, facilitating the fermentation of tea leaves.

[0042] Embodiment 1:

[0043] Refer to Figures 1 - 11, A tea fermentation processing device, including a fermentation tank 1 and mounting rings 6 symmetrically arranged on the inner wall of the fermentation tank 1, further comprising: a moving mechanism arranged on the mounting ring 6, a placing plate 15 is arranged on the moving mechanism, and the moving mechanism is used to drive the placing plate 15 to move along the direction of the mounting ring 6; a material turning mechanism arranged on the placing plate 15, when the placing plate 15 moves, it is used to turn the tea on the placing plate 15. Among them, a counterweight 23 is fixedly connected to the bottom of the placing plate 15, and when the placing plate 15 moves, it is used to keep the placing plate 15 in a horizontal state; a feed hopper 25 is fixedly connected to the top of the fermentation tank 1, and a discharging mechanism is arranged inside the feed hopper 25, which is used to spread the tea in the feed hopper 25 on the top placing plate 15. Among them, a monitor 24 is arranged on the top of the inner wall of the fermentation tank 1; a mounting seat 38 is fixedly connected to the outer wall of the fermentation tank 1, a driving motor 39 is fixedly connected to the mounting seat 38, the output end of the driving motor 39 is fixedly connected with an adjusting mechanism, and a slip ring 41 rotatably connected to the adjusting mechanism is fixedly connected to the mounting seat 38; a linkage mechanism is arranged between the outer wall of the fermentation tank 1 and the adjusting mechanism, which is used to adjust the moving mode and moving condition of the placing plate 15. In addition, it can control the discharge of tea from the feed hopper 25 to the placing plate 15.

[0044] In this embodiment, tea can be placed through the feed hopper 25. When the driving motor 39 is started, the tea can be evenly spread on the placing plate 15 through the discharging mechanism. After the tea on one group of placing plates 15 is spread, the remaining placing plates 15 are sequentially conveyed below the discharging mechanism through the moving mechanism until the spreading of the tea on all the placing plates 15 is completed, so as to realize the rapid spreading of tea and improve the production efficiency of tea. Subsequently, the linkage mechanism drives the moving mechanism to drive the placing plate 15 to slowly move along the inside of the fermentation tank 1, and during the moving process, the tea on the placing plate 15 is turned by the material turning mechanism, which can not only avoid the situation of missed turning, but also reduce the entry of bacteria and dust in the external environment when the tea is turned, thereby improving the fermentation quality of tea;

[0045] A box door 2 is further arranged on the fermentation tank 1, and an observation port is opened on the box door 2 to facilitate real-time observation of the fermentation situation of the tea. Multiple groups of universal wheels 3 are arranged at the bottom of the fermentation tank 1 for moving the fermentation tank 1. A temperature control system 4 and a humidity control system 5 are also arranged on the fermentation tank 1. The specific structures of the temperature control system 4 and the humidity control system 5 can refer to the technical solutions in the prior art, and those skilled in the art can know that they are used to control the temperature and humidity in the fermentation tank 1.

[0046] Refer to Figure 4 、 Figure 5 、 Figure 6 、 Figure 10 and Figure 11, the movable mechanism includes an annular groove 7 formed in the mounting ring 6. An internal rack 8 is fixedly connected to the inner wall of the annular groove 7. An activity shaft 9 is arranged between the annular groove 7 and the inner wall of the mounting ring 6. A plurality of movable gears 10 meshing with the internal rack 8 are fixedly connected to the activity shaft 9. The placing plate 15 is rotatably connected between the two activity shafts 9 on both sides. A first driven wheel 11 is fixedly connected to the activity shaft 9. A fixed shaft 12 is rotatably connected inside the fermentation box 1. A first driving wheel 13 is fixedly connected to the fixed shaft 12. A first belt 14 is sleeved between the first driving wheel 13 and the first driven wheel 11. Among them, one side of the activity shaft 9 away from the internal rack 8 is in contact with the mounting ring 6, and the first belt 14 has elasticity.

[0047] In this embodiment, it should be explained that when the movable gear 10 rotates and moves inside the mounting ring 6, the length of the first belt 14 will change according to the situation. During this process, the first belt 14 is in a tightly fitting state with both the first driving wheel 13 and the first driven wheel 11; when it is necessary to switch the position of the placing plate 15, by driving the movable gear 10 to rotate a specified number of turns, the position of the placing plate 15 can be changed (the previous placing plate 15 moves to the next placing plate 15). In addition, when the fixed shaft 12 is not subjected to external force, it will not rotate due to the gravity of the placing plate 15, so as to facilitate the stable switching of the placing plate 15, thereby ensuring the stability of the tea spreading; when the tea spreading is completed, then by driving the fixed shaft 12 to rotate continuously and slowly, the movable gear 10 can be driven to rotate inside the mounting ring 6. Under the action of the internal rack 8, the placing plate 15 can be driven to slowly move inside the fermentation box 1, so as to ensure that the placing plates 15 at different positions can pass through different positions of the fermentation box 1, thereby ensuring the stability of the tea fermentation progress and effect.

[0048] Refer to Figure 4 , Figure 5 and Figure 7 , the material turning mechanism includes a second driving wheel 16 fixedly connected to the activity shaft 9. A first reciprocating lead screw 17 is rotatably connected to the outer side wall of the placing plate 15. A second driven wheel 18 is fixedly connected to the end of the first reciprocating lead screw 17. A second belt 19 is sleeved between the second driving wheel 16 and the second driven wheel 18. A sliding seat 20 is arranged on the first reciprocating lead screw 17. A limiting groove 21 is formed in the side of the placing plate 15 close to the sliding seat 20. A turning plate 22 slidably connected to the limiting groove 21 is fixedly connected to the sliding seat 20. Among them, the turning plate 22 extends from the limiting groove 21 into the interior of the placing plate 15. The part of the turning plate 22 located inside the placing plate 15 is arranged in a conical shape, and the bottom of the turning plate 22 is in contact with the bottom of the placing plate 15.

[0049] In this embodiment, during the movement of the placing plate 15, since the movable shaft 9 is in a rotating state, and the placing plate 15 is always in a horizontal state under the action of the counterweight 23, that is, at this time, a relative rotating state exists between the placing plate 15 and the movable shaft 9, so that the second driving wheel 16 drives the second driven wheel 18 to rotate, driving the first reciprocating lead screw 17 to rotate, driving the turning plate 22 to reciprocate along the placing plate 15 through the sliding seat 20. In addition, the bottom of the limiting groove 21 can be set to be corrugated to drive the turning plate 22 to move in a vibrating state to avoid tea leaves accumulating at the turning plate 22. In addition, by setting the moving speed of the placing plate 15, the time required for the turning plate 22 to move a single-way placing plate 15 can be adjusted, and the situation of too low or too high frequency of turning the tea leaves by the turning plate 22 can be avoided, thereby ensuring the fermentation effect of the tea leaves.

[0050] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 , the discharging mechanism includes a discharging shaft 26 rotatably connected in the discharging hopper 25. A discharging plate 27 matching the inner wall of the discharging hopper 25 is fixedly connected to the discharging shaft 26. An extension member 28 is fixedly connected to the outer wall of the discharging hopper 25. The extension member 28 is located above the discharging plate 27. A discharging member 31 is communicated with the bottom of the discharging hopper 25. One end of the discharging member 31 away from the discharging hopper 25 is fixedly connected to a spreading member 32. On one side of the fermentation tank 1 close to the spreading member 32, second reciprocating lead screws 33 are symmetrically rotatably connected. Among them, the spreading member 32 is located above the uppermost placing plate 15. The discharging member 31 is made of an elastic material. The spreading member 32 is connected to the second reciprocating lead screw 33, and the pitch of the thread groove on the surface of the second reciprocating lead screw 33 is in the order of small-large-small. On one side of the inner wall of the fermentation tank 1 close to the spreading member 32, elastic compression rods 34 are symmetrically fixedly connected.

[0051] In this embodiment, when spreading the tea leaves, by driving the discharging shaft 26 to drive the discharging plate 27 to rotate, the tea leaves in the discharging hopper 25 can fall onto the uppermost placing plate 15 through the discharging member 31 and the spreading member 32. It should be noted that the setting of different pitch of the thread groove on the surface of the second reciprocating lead screw 33 is a conventional means in the prior art, which can make the spreading member 32 move at different speeds along the surface of the second reciprocating lead screw 33 (since the length of the discharging member 31 is different when the spreading member 32 is at different positions on the placing plate 15, that is, the discharging speed of the tea leaves is different. By adjusting the moving speed of the spreading member 32 and the discharging speed of the tea leaves, the tea leaves can be evenly spread on the placing plate 15). When the spreading of the tea leaves on a single set of placing plates 15 is about to be completed, the spreading member 32 will compress the elastic compression rods 34, thereby monitoring the spreading situation of the tea leaves on the placing plate 15 to facilitate switching of the placing plate 15.

[0052] Refer to Figures 1 - 3 At the top of the fermentation box 1, a rotating shaft 29 is rotatably connected. A bevel gear set 30 is arranged between the rotating shaft 29 and the blanking shaft 26. At one end of the rotating shaft 29 away from the bevel gear set 30 and at the end of the second reciprocating lead screw 33, belt pulleys 35 are fixedly connected. A third belt 36 is sleeved between multiple groups of belt pulleys 35.

[0053] In this embodiment, when one group of belt pulleys 35 rotates, multiple groups of belt pulleys 35 will be driven to rotate synchronously through the third belt 36, thereby driving the second reciprocating lead screw 33 and the rotating shaft 29 to rotate synchronously. When the tea leaves are discharged from the hopper 25, the spreading member 32 can be driven to move along the placing plate 15, and the tea leaves are evenly spread on the placing plate 15 to facilitate the fermentation of the tea leaves.

[0054] Refer to Figure 2 、 Figure 3 、 Figure 9 and Figure 10 The adjusting mechanism includes a telescopic main shaft 40 fixedly connected to the output end of the driving motor 39. A telescopic sub-shaft 42 is arranged inside the telescopic main shaft 40. A slip ring 41 rotatably connected to the telescopic main shaft 40 is fixedly connected to the mounting seat 38. A piston 43 is slidably connected inside the telescopic sub-shaft 42. A connecting shaft 44 is fixedly connected to the side of the piston 43 away from the telescopic main shaft 40. Among them, the piston 43 divides the inside of the telescopic sub-shaft 42 into two compression chambers. A first connecting pipe 45 and a second connecting pipe 46 are respectively communicated between the slip ring 41 and the two compression chambers. The first connecting pipe 45 penetrates through the piston 43, and check valves are arranged at the ends of the first connecting pipe 45 and the second connecting pipe 46. First pressure relief valves 47 are arranged on the side walls of the telescopic sub-shaft 42 close to the two compression chambers. Connecting channels 48 are respectively communicated between the first connecting pipe 45 and the second connecting pipe 46 and the two first pressure relief valves 47. The first pressure relief valves 47 adopt pneumatic valves. The telescopic main shaft 40 and the telescopic sub-shaft 42 adopt electric type and are electrically connected to the monitor 24 through the slip ring 41. The exhaust port of the elastic compression rod 34 is connected to the first connecting pipe 45 through the slip ring 41.

[0055] In this embodiment, it should be explained that the slip ring 41 is a conventional means in the prior art and can be used to achieve stable connection of gas, liquid or electricity for rotating equipment. Therefore, it will not be elaborated here. After a single set of the placing plates 15 is spread, the gas compressed by the elastic compression rod 34 will enter one of the compression cavities through the slip ring 41 and the first connecting pipe 45 to adjust the overall length of the telescopic secondary shaft 42 and the connecting shaft 44, so as to facilitate switching the working state of the equipment. At this time, the spreading of the tea leaves is stopped. Subsequently, the position of the placing plate 15 is adjusted to facilitate spreading the tea leaves on different placing plates 15. After the position adjustment of the placing plate 15 is completed, the gas compressed by the support rod 57 enters another compression cavity, and at the same time, the gas in its corresponding compression cavity is discharged through the first pressure relief valve 47 to ensure the stability of the adjustment of the overall length of the telescopic secondary shaft 42 and the connecting shaft 44. The subsequent spreading of the tea leaves is the same as the above process. Until the tea leaves are spread on all the placing plates 15, the overall lengths of the telescopic main shaft 40 and the telescopic secondary shaft 42 are controlled by the monitor 24 to stop the spreading of the tea leaves, thereby ensuring the stability of the spreading of the tea leaves.

[0056] Refer to Figure 2 and Figure 10 , the linkage mechanism includes a sector gear 49 fixedly connected to the connecting shaft 44 and a driving gear 50. One end of the fixed shaft 12 is fixedly connected with a first driven gear 51 meshing with the sector gear 49 and the driving gear 50. One side of the fermentation box 1 close to the driving gear 50 is rotatably connected with a second driven gear 52. One side of the second driven gear 52 far from the fermentation box 1 is fixedly connected with a third driving wheel 53. One end of one of the second reciprocating lead screws 33 is fixedly connected with a third driven wheel 37. A fourth belt 54 is sleeved between the third driving wheel 53 and the third driven wheel 37. It further includes a fixing plate 55 fixedly connected to the mounting seat 38. One side of the fixing plate 55 close to the sector gear 49 is rotatably connected with a rotating plate 56. One side of the fixing plate 55 close to the rotating plate 56 is fixedly connected with a support rod 57. Among them, the support rod 57 is elastic, and the exhaust port of the support rod 57 is communicated with the second connecting pipe 46 through the slip ring 41. When the sector gear 49 meshes with the first driven gear 51, it is in the same plane as the rotating plate 56 and has the same size. One side of the rotating plate 56 close to the driving gear 50 is inclined.

[0057] In this embodiment, when the driving gear 50 meshes with the second driven gear 52, the spreading operation of the tea leaves can be achieved. When the driving gear 50 disengages from the second driven gear 52 and the sector gear 49 meshes with the first driven gear 51, the fixed shaft 12 can be driven to rotate a specified number of turns, thereby adjusting the position of the placing plate 15 so as to spread the tea leaves on different placing plates 15. And after the position of the placing plate 15 is adjusted, the sector gear 49 will squeeze the rotating plate 56, thereby compressing the support rod 57 to adjust the positions of the sector gear 49 and the driving gear 50, so that the driving gear 50 meshes with the second driven gear 52 again to continue the spreading operation of the tea leaves until the spreading of the tea leaves is completed.

[0058] Referring to Figure 1 , Figure 2 and Figure 8 , it further includes a baffle 58 slidably connected in the extension member 28. A spring 59 is fixedly connected between the baffle 58 and the inner wall of the extension member 28. A one-way valve and a second pressure relief valve 60 are provided on the side wall of the extension member 28. Among them, the one-way valve is connected to the exhaust port of the elastic compression rod 34, and the second pressure relief valve 60 is pneumatic and is connected to the exhaust port of the support rod 57.

[0059] In this embodiment, during the spreading process of the tea leaves, when the tea leaves are about to be spread to the end of the placing plate 15 (i.e., when squeezing the elastic compression rod 34), part of the gas will be conveyed into the extension member 28 to drive the baffle 58 to move into the hopper 25, thereby reducing the discharge amount of the tea leaves and avoiding too thick tea leaves being spread at the end of the placing plate 15. And when the spreading of a single group of placing plates 15 is completed and the position of the subsequent placing plates 15 is adjusted, the gas compressed by the support rod 57 enters the second pressure relief valve 60, so that the gas in the extension member 28 is discharged under the action of the spring 59, and then the baffle 58 moves to the initial position to ensure the stability of the tea leaf spreading at the beginning.

[0061] Basically the same as Embodiment 1, a tea leaf fermentation and processing method is proposed on the basis of Embodiment 1, including the following steps:

[0062] Step 1: Add the tea leaves to be fermented to the equipment, and then start the equipment;

[0063] Step 2: Then automatically spread the tea leaves at the uppermost position in the equipment;

[0064] Step 3: After the spreading at the uppermost position is completed, convey the tea leaves at the uppermost position to other positions;

[0065] Step 4: When the spreading of the tea leaves is completely completed, slowly drive the tea leaves in the equipment to move evenly along different positions of the equipment;

[0066] Step Five: During the movement of the tea leaves in the device, when the fermentation reaches the specified period, the single flipping of the tea leaves is completed.

[0067] Step Six: Until the corresponding color changes appear in each type of tea leaves, the fermentation process of the tea leaves is completed.
