Description

Technical Field

[0001] This application relates to the field of tea fermentation technology, and in particular to a temperature and humidity controlled tea fermentation device. Background Technology

[0002] Fermentation is the core process that determines the color, aroma, and flavor of tea. It has stringent requirements for temperature, humidity, ventilation, and uniformity. Traditional tea fermentation often relies on the natural environment or simple workshops, using manual watering, charcoal heating, and regular turning to regulate temperature and humidity. Temperature and humidity are easily affected by seasons, day and night, and geographical location, resulting in large fluctuations and low precision, making it difficult to maintain a stable and suitable fermentation range. Traditional fermentation equipment is prone to problems such as excessive surface moisture, excessive internal dryness, and localized heat accumulation. Furthermore, it is highly dependent on manual labor and inefficient, making it difficult to meet the needs of large-scale and standardized production. Therefore, developing temperature and humidity controlled tea fermentation equipment is of great significance for stabilizing quality, improving efficiency, and promoting the intelligent upgrading of tea processing.

[0003] The existing technology still has the following problems: 1. Existing tea fermentation equipment is unable to evenly turn the tea leaves. Some tea leaves settle and adhere to the bottom and cannot be turned over. This directly leads to significant differences in temperature and humidity between the inside and the surface of the tea pile, as well as between the upper and lower layers. Poor internal ventilation, heat and moisture accumulation, and problems such as excessively fast fermentation and over-fermentation also occur. Incomplete turning can also cause the leaves to stick together and clump, increasing the cost of manual sorting. The batch stability is extremely poor, making it difficult to achieve standardized production and directly restricting the improvement of tea quality and large-scale processing.

[0004] 2. In existing tea fermentation devices, water mist is sprayed only on one side of the tea leaves during temperature and humidity control, which causes severe uneven humidification. Unilateral humidification leads to an imbalance in the temperature and humidity distribution of the leaf pile, with localized heat accumulation and localized cooling, disrupting the fermentation process and making it difficult to achieve standardized and uniform fermentation. In addition, when the fan promotes air circulation and gas exchange within the device, a large number of water droplets easily adhere to the inner wall of the pipes. During the fermentation process, these droplets fall onto the tea leaves, causing a sudden increase in localized moisture content, resulting in uneven fermentation and quality deterioration. Summary of the Invention

[0005] To overcome the shortcomings of tea fermentation devices, such as the difficulty in evenly turning tea leaves, resulting in some leaves settling and adhering to the bottom and failing to turn, leading to significant temperature and humidity differences between the inside and surface of the tea pile, as well as between the upper and lower layers, poor internal ventilation, heat and moisture accumulation, and excessively rapid or over-fermentation, this invention aims to provide a temperature and humidity controlled tea fermentation device to address these deficiencies. Incomplete turning can also cause leaves to stick together and clump, increasing manual sorting costs, resulting in extremely poor batch stability, and hindering standardized production. Furthermore, when controlling temperature and humidity in tea fermentation devices, water mist is sprayed only on one side of the tea leaves, causing severe uneven humidification. Unilateral humidification leads to an imbalance in temperature and humidity distribution within the leaf pile, resulting in localized heat accumulation and localized cooling, disrupting the fermentation process and making standardized and uniform fermentation difficult. Additionally, when the fan promotes air circulation and gas exchange within the device, a large amount of water droplets easily adhere to the inner wall of the pipes. These droplets fall onto the tea leaves during fermentation, causing a sudden increase in localized moisture content, leading to uneven fermentation and quality deterioration.

[0016] The technical solution provided in this application has at least the following technical effects or advantages: 1. By employing a fermentation component, this invention effectively solves the problems of existing tea fermentation devices, which struggle to evenly turn the tea leaves. This results in some tea leaves settling and adhering to the bottom, leading to significant temperature and humidity differences between the inside and surface layers, as well as between the upper and lower layers. Poor ventilation, heat and moisture accumulation, and excessively rapid or over-fermentation are also problems. Incomplete turning can cause leaves to stick together and clump, increasing manual sorting costs and resulting in extremely poor batch stability, hindering standardized production and directly restricting tea quality improvement and large-scale processing. This invention, through its fermentation component, allows the tea leaves to shake during stirring, preventing them from settling or adhering to the bottom. Furthermore, the periodic floating of the stirring leaves during turning expands the turning area and breaks up dead zones. The shaking continuously loosens and repositions the tea leaves, preventing clumping and ensuring each leaf is evenly exposed to air, temperature, humidity, and moisture. This eliminates dead zones caused by overheating, excessive humidity, and lack of oxygen, significantly improving mixing uniformity, reducing manual intervention, and thus increasing production efficiency.

[0017] 2. By employing a temperature and humidity control component, this invention effectively solves the problem of existing tea fermentation devices where water mist is sprayed only on one side of the tea leaves, resulting in severely uneven humidification. Unilateral humidification leads to an imbalance in temperature and humidity distribution in the leaf pile, causing localized heat accumulation and localized cooling, disrupting the fermentation process and making it difficult to achieve standardized and uniform fermentation. Furthermore, when the fan promotes air circulation and gas exchange within the device, a large number of water droplets easily adhere to the inner wall of the pipes. During fermentation, these droplets fall onto the tea leaves, causing a sudden increase in localized moisture content, leading to uneven fermentation and quality deterioration. This invention, through its temperature and humidity control component, uses a reciprocating motion to spray water evenly. This reciprocating motion ensures that the water mist covers the entire area of ​​the tea leaves, avoiding localized over-humidification and localized dryness caused by unilateral spraying. This ensures that each tea leaf absorbs water evenly and maintains a balanced humidity, providing a stable environment for fermentation. In addition, the efficiency of air circulation and gas exchange can be adjusted according to needs, and the backflow of water mist from the inner wall of the fan pipes can be prevented from affecting subsequent tea fermentation, providing an important guarantee for standardized and intelligent tea fermentation.

Detailed Implementation

[0020] For tea fermentation devices that struggle to evenly turn tea leaves, this invention addresses the issue by using a fermentation component that causes the tea leaves to sway during stirring and turning, preventing them from settling or adhering to the bottom. Furthermore, the stirring process involves periodic floating of the tea leaves. To prevent uneven temperature and humidity distribution caused by unilateral humidification, this invention utilizes a temperature and humidity control component that sprays water evenly in a reciprocating motion. This reciprocating motion ensures the water mist covers the entire tea leaf area, avoiding localized over-wetting or under-wetting caused by unilateral spraying. This results in consistent water absorption and balanced humidity for each tea leaf, providing a stable environment for fermentation.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example 1

[0022] Please see Figure 1As shown, a temperature and humidity controlled tea fermentation device includes a fermentation chamber 1 and an atomizing chamber 2. The bottom wall of the fermentation chamber 1 is equipped with the atomizing chamber 2, which includes a water tank, a water supply valve, and an ultrasonic atomizer. The inner wall of the fermentation chamber 1 is equipped with a sensor for real-time collection of temperature and humidity data of the fermentation environment, accurately monitoring the temperature and humidity changes inside the leaf pile and within the device, providing a reliable basis for system regulation. The outer surface of the fermentation chamber 1 is equipped with a control panel for controlling the operation of the overall mechanism of the fermentation chamber 1. A limit strip 3 is fixedly installed on the inner wall of the fermentation chamber 1, and a fermentation component 4 is slidably connected to the inner cavity of the limit strip 3. A temperature and humidity controlled component 5 is installed in the inner cavity of the fermentation chamber 1. The fermentation component 4 is moved to the position inside the limit strip 3, and tea leaves are placed in the fermentation component 4. The fermentation component 4 can evenly turn the tea leaves during the fermentation process. The ultrasonic atomizer is used to break the water in the atomizing chamber 2 into tiny droplets, which are then evenly sprayed through the temperature and humidity controlled component 5.

[0023] Please see Figure 2 and Figure 3 As shown, the fermentation assembly 4 includes a fermentation rack 41, a fermentation frame 42 slidably connected to the inner cavity of the fermentation rack 41, a stirring rod 43 rotatably connected to the inner wall of the fermentation rack 41, a rotating mechanism 44 on the outer surface of the fermentation rack 41, a first motor 45 on the outer surface of the rotating mechanism 44, a flipping mechanism 46 sleeved on the outer surface of the stirring rod 43, and a shaking mechanism 47 on the outer surface of the fermentation rack 41. The fermentation frame 42 consists of a bottom plate and side plates, with evenly spaced connecting holes in the bottom plate. The fermentation rack 41 and the limiting strip 3 are slidably connected. When tea leaves are placed in the container formed by the fermentation rack 41 and the fermentation frame 42, the first motor 45 drives the rotating mechanism 44 to drive the three stirring rods 43 to rotate. The rotation of the stirring rods 43 drives the flipping mechanism 46 to flip the tea leaves on the fermentation rack 41. At the same time, the rotation of the stirring rods 43 drives the shaking mechanism 47 to drive the fermentation frame 42 to shake up and down in the inner cavity of the fermentation rack 41, thereby preventing the tea leaves from settling and adhering to the bottom wall of the fermentation frame 42. The flipping mechanism 46, in conjunction with the fermentation rack 41, can evenly flip the tea leaves.

[0024] Please see Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the rotating mechanism 44 includes a fixed frame 441, which is fixedly connected to the fermentation rack 41. A rotating rod 442 is rotatably connected to the inner cavity of the fixed frame 441. The output end of the first motor 45 is sleeved with the rotating rod 442. A first bevel gear 443 is fixedly connected to the outer surface of the rotating rod 442. A second bevel gear 444 is rotatably connected to the inner wall of the fermentation rack 41. The first bevel gear 443 and the second bevel gear 444 mesh. The second bevel gear 444 is fixedly connected to the stirring rod 43. The flipping mechanism 46 includes a first connecting block 461, a connecting ring 462 is slidably connected to the inner cavity of the first connecting block 461, a first protrusion 463 is fixedly installed on the outer surface of the connecting ring 462, and a rotating ring 464 is provided on one side of the connecting ring 462. A sleeve 465 is fixedly installed on the outer surface of the rotating ring 464. A floating ring 466 is slidably connected to the end of the sleeve 465 away from the connecting ring 462. A spring rod 467 is fixedly connected to the inner wall of the rotating ring 464. A first spring 468 is sleeved on the outer surface of the spring rod 467. A ball 469 is movably connected to one end of the spring rod 467. A rotating blade 4610 is fixedly installed on the outer surface of the sleeve 465. The first connecting block 461 is fixedly connected to the bottom plate of the fermentation frame 42. The floating ring 466 is fixedly connected to the stirring rod 43. The first spring 468 is located between the rotating ring 464 and the floating ring 466. When the floating ring 466 rotates, the ball 469 passes the first protrusion 463 and drives the rotating ring 464 to compress the first spring 468. The spring rod 467 and the floating ring 466 are connected to the inner wall of the rotating ring 464. A first spring 468 is sleeved on the outer surface of the spring rod 467. A ball 469 is movably connected to the outer wall of the rotating ring 464. A rotating blade 4610 is fixedly installed on the outer surface of the sleeve 465. A rotating blade 4610 is fixedly installed on the outer surface of the sleeve 465. A rotating blade 4610 is fixedly connected to the inner wall of the rotating ring 464. A rotating blade 46 ... The moving ring 466 is slidably connected, the rotating ring 464 and the stirring rod 43 do not contact each other, the connecting ring 462 and the stirring rod 43 are rotatably connected, and there is a gap between the connecting ring 462 and the sleeve 465. The shaking mechanism 47 includes a connecting strip 471, both ends of the connecting strip 471 are fixedly connected to the fermentation frame 42, a second protrusion 472 is fixedly installed on the upper surface of the connecting strip 471, the connecting strip 471 is slidably connected to the outer surface of the fermentation rack 41, a fixing ring 473 is fixedly installed on one end of the stirring rod 43, and a pressing rod 474 is fixedly installed on the outer surface of the fixing ring 473. When the stirring rod 43 rotates, the pressing rod 474 presses against the second protrusion 472. A connecting rod 475 is fixedly installed on the inner wall of the fermentation rack 41, and a second spring 476 is sleeved on the outer surface of the connecting rod 475. The two ends of the connecting strip 471 are slidably connected to the connecting rod 475. The second spring 476 is located between the lower surface of the connecting strip 471 and the bottom wall of the fermentation rack 41. When the tea leaves in the fermentation rack 41 and the fermentation frame 42 are turned, the first motor 45 drives the rotating rod 442 to rotate in the inner cavity of the fixed frame 441. The rotation of the rotating rod 442 drives the first bevel gear 443 to rotate, the rotation of the first bevel gear 443 drives the second bevel gear 444 to rotate, the rotation of the second bevel gear 444 drives the stirring rod 43 to rotate, the rotation of the stirring rod 43 drives the floating ring 466 to rotate, the rotation of the floating ring 466 drives the elastic rod 467 to rotate, and the rotation of the elastic rod 467 drives the rolling ball 469 to move from the lower end to the upper end of the first protrusion 463.This causes the first protrusion 463 to press against the rolling ball 469. At this time, the rotating ring 464 drives the sleeve 465 to move towards the floating ring 466 and press against the first spring 468. The rotation of the floating ring 466 drives the sleeve 465 to rotate, and the rotation of the sleeve 465 drives the flipping blade 4610 to flip the tea leaves. With three stirring rods 43 and three flipping mechanisms 46 for each stirring rod 43, the tea leaves can be flipped more evenly. In addition, the flipping blade 4610 produces a small amplitude sway during rotation, which helps to disperse the tea leaves, thereby better controlling the temperature and humidity of the water mist and improving the quality of the tea. Furthermore, the rotation of the stirring rod 43 drives the fixed ring 473 to rotate, and the rotation of the fixed ring 473 drives the pressing rod 474 to press against the second protrusion 472. The force on the second protrusion 472 causes the connecting strip 471 to move downward. The downward movement of the connecting strip 471 causes the connecting strip 471 to slide on the connecting rod 475 and press against the second spring. The compression generated by step 476 causes the connecting strip 471 to move downwards, pulling the fermentation frame 42 down into the inner cavity of the fermentation rack 41. At this time, the bottom end of the connecting ring 462 slides within the inner cavity of the first connecting block 461, while the first protrusion 463 continuously compresses the passing rolling ball 469. The elastic force of the first spring 468 causes the sleeve 465 to return to its original position, and simultaneously, the elastic force of the second spring 476 causes the fermentation frame 42 to return to its original position. This causes the tea leaves to sway back and forth during the turning process, preventing them from settling or adhering to the bottom of the fermentation frame 42. Furthermore, the stirring blades periodically float during the turning process, expanding the turning area and breaking up dead zones of material accumulation. The shaking allows the tea leaves to continuously loosen and reposition themselves during the turning process, preventing leaf accumulation and clumping. This ensures that each tea leaf is evenly exposed to air, temperature, humidity, and water mist, eliminating dead zones of localized overheating, excessive humidity, and oxygen deficiency, significantly improving mixing uniformity, reducing manual intervention, and thus increasing production efficiency. Example 2

[0025] Please see Figure 1 and Figure 2 As shown, the temperature and humidity control component 5 includes a humidity control mechanism 51, a connecting pipe 52 at the bottom of the humidity control mechanism 51, a temperature control mechanism 53 on the top wall of the fermentation box 1, and a conduit 54 on the upper surface of the temperature control mechanism 53. Water mist in the atomizing box 2 is transported to the humidity control mechanism 51 through the connecting pipe 52 and sprayed evenly. The temperature control mechanism 53 and the conduit 54 are used to promote air circulation and gas exchange in the fermentation box 1, thereby controlling the temperature and humidity.

[0026] Please see Figure 8 and Figure 9As shown, the humidity control mechanism 51 includes a humidity control frame 511, which is fixedly connected to the inner wall of the fermentation chamber 1. A second motor 512 is installed on the outer surface of the humidity control frame 511. A gear frame 513 is slidably connected to the inner wall of the humidity control frame 511. A semi-ring gear 514 is rotatably connected to the middle part of the humidity control frame 511. Half of the semi-ring gear 514 is hollowed out, which allows the gear frame 513 to reciprocate within the inner cavity of the humidity control frame 511. The gear frame 513 and the semi-ring gear 514 mesh. Spray pipes 515 are fixedly connected to both ends of the gear frame 513. A nozzle 516 is installed on the outer surface of the spray pipe 515. A connecting pipe 52 is fixedly connected to the bottom end of the spray pipe 515. The connecting pipe 52 is slidably connected to the inner cavity of the atomizing box 2. The connecting pipe 52 is made of soft material and can extend and retract within the inner cavity of the atomizing box 2 to cooperate with the spray pipe 515. The number of spray nozzles 516 and fermentation components 4 are equal and located above the fermentation components 4. The output end of the second motor 512 is connected to the semi-ring gear 514. The operation of the second motor 512 drives the semi-ring gear 514 to rotate. The rotation of the semi-ring gear 514 drives the gear frame 513 to move back and forth in the inner cavity of the humidity control frame 511, thereby driving the spray pipe 515 to move back and forth inside the fermentation box 1. This allows the spray nozzles 516 to spray the fermentation components 4 evenly one by one. The reciprocating movement allows the water mist to cover the entire area of ​​the tea leaves, avoiding local over-wetting or local dryness caused by unilateral spraying. This ensures that each tea leaf absorbs water evenly and has a balanced humidity, providing a stable environment for fermentation. The moving spray forms a fine and uniform mist field. The leaves absorb moisture gently without water accumulation, preventing clumping, sticking, and stale taste, and ensuring the cleanliness of the fermentation.

[0027] Please see Figure 2 and Figure 10 As shown, the temperature control mechanism 53 includes a ventilation box 531, which is fixedly connected to the top wall of the fermentation box 1. Both ends of the inner wall of the ventilation box 531 are equipped with exhaust mechanisms 532. A baffle plate 533 is fixedly installed on the inner wall of the ventilation box 531. A ventilation plate 534 is slidably connected to the inner cavity of the ventilation box 531. A ventilation pipe 535 is fixedly installed on the lower surface of the ventilation plate 534. Ventilation holes 536 are opened on the outer surface of the ventilation pipe 535. An adjustment mechanism 537 is provided in the middle of the ventilation box 531. A fourth adjustment mechanism 537 is provided on the outer surface of the ventilation box 531. Motor 538 and ventilation holes 536 are located between baffles 533 and baffles 533. The duct 54 is connected to the ventilation box 531. The operation of the fourth motor 538 drives the adjustment mechanism 537 to change the height of the ventilation plate 534, which in turn changes the position of the ventilation pipe 535 in the inner cavity of the baffle 533. This changes the number of ventilation holes 536 exposed at the lower end of the baffle 533. In conjunction with the operation of the exhaust mechanism 532, the air flow speed in the inner cavity of the ventilation box 531 changes, thereby adjusting the humidity and temperature inside the fermentation box 1.

[0028] Please see Figure 11 , Figure 12 and Figure 13As shown, the exhaust mechanism 532 includes a fixed plate 5321, which is fixedly connected to the inner wall of the ventilation box 531. A buffer plate 5322 is provided in the middle of the fixed plate 5321. A slide rod 5323 is fixedly installed on the outer surface of the buffer plate 5322. The slide rod 5323 is slidably connected to the fixed plate 5321. A third spring 5324 is sleeved on the outer surface of the slide rod 5323. The third spring 5324 is located between the fixed plate 5321 and the buffer plate 5322. A third motor 5325 is provided in the middle of the buffer plate 5322. The third motor 5325 is a stepper motor for easy control of fresh air intake or exhaust. When the fan rotates in the forward direction, fresh air is drawn in from the outside and sent into the fermentation box 1 to supplement the oxygen required for fermentation and promote the fermentation of tea. Phenol oxidation, while ensuring uniform airflow within the chamber to prevent localized stuffiness and humidity, and when the fan rotates in the opposite direction, expelling the hot, humid mist, carbon dioxide, and excess heat from the chamber, prevents excessive temperature and humidity from causing over-fermentation or mold growth, thereby controlling the temperature and humidity inside fermentation chamber 1. An exhaust fan 5326 is rotatably connected to the lower surface of the buffer plate 5322. The output end of the third motor 5325 is connected to the exhaust fan 5326. The adjustment mechanism 537 includes a protective box 5371, which is fixedly connected to the inner wall of the ventilation box 531. A moving block 5372 is slidably connected to the inner cavity of the protective box 5371. A threaded rod 5373 is rotatably connected to the inner wall of the ventilation box 531. The moving block 5372 and the threaded rod 5373 are connected by threads. The ventilation box 5... A limit rod 5374 is fixedly installed on the inner wall of the protective box 5371. The moving block 5372 and the limit rod 5374 are slidably connected. A groove is opened at the bottom end of the protective box 5371. A second connecting block 5375 is slidably connected to the inner cavity of the protective box 5371. The moving block 5372 and the second connecting block 5375 are fixedly connected. The upper surface of the second connecting block 5375 is tightly fitted with the groove. A drive rod 5376 is rotatably connected to the inner wall at the bottom end of the second connecting block 5375. A lifting block 5377 is fixedly installed on the upper surface of the ventilation plate 534. A drive groove 5378 is opened on the outer surface of the lifting block 5377. The drive rod 5376 and the drive groove 5378 are slidably connected. By flexibly fixing the exhaust fan 5326 to the fixed plate 5321, air circulation can be reduced. The noise generated during operation causes the third motor 5325 to cause the buffer plate 5322 to shake. At this time, the slide rod 5323 shakes in the inner cavity of the fixed plate 5321 and compresses the third spring 5324. The elastic force of the third spring 5324 reduces the resonance noise. When it is necessary to increase air circulation, the operation of the fourth motor 538 drives the threaded rod 5373 to rotate. The rotation of the threaded rod 5373 causes the moving block 5372 to move on the protective box 5371 and the limit rod 5374. The movement of the moving block 5372 causes the second connecting block 5375 to move. The movement of the second connecting block 5375 causes the drive rod 5376 to slide on the drive groove 5378 on the lifting block 5377, thereby changing the height of the lifting block 5377.The upgrade of the lifting block 5377 changes the position of the ventilation plate 534 within the ventilation box 531, causing a change in the position of the ventilation pipe 535 within the baffle plate 533. This adjusts the number of ventilation holes 536 below the baffle plate 533, thereby altering the ventilation efficiency. Air is supplied inwards when oxygen replenishment is needed, and exhausted outwards when humidity or temperature is too high. Furthermore, by retracting the ventilation holes 536, water mist and droplets adhering to the inner wall of the pipes will not flow back when ventilation is not required, thus providing crucial protection for tea fermentation.

[0029] In summary, tea leaves are placed in the container formed by the fermentation rack 41 and the fermentation frame 42. The operation of the first motor 45 drives the rotating mechanism 44 to drive the three stirring rods 43 to rotate. The rotation of the stirring rods 43 drives the flipping mechanism 46 to turn the tea leaves on the fermentation rack 41. At the same time, the rotation of the stirring rods 43 drives the shaking mechanism 47 to drive the fermentation frame 42 to shake up and down in the inner cavity of the fermentation rack 41, thereby preventing the tea leaves from settling and adhering to the bottom wall of the fermentation frame 42. With the help of the flipping mechanism 46, the tea leaves can be turned evenly. The water mist in the atomizing box 2 is delivered to the humidity control mechanism 51 through the connecting pipe 52 and sprayed evenly. The temperature control mechanism 53 and the conduit 54 are used to promote air circulation and gas exchange in the fermentation box 1 to achieve temperature and humidity control.
