Description

Technical Field

[0001] This invention relates to the field of tea fermentation technology, and in particular to a tea fermentation machine and fermentation method that are easy to control in temperature. Background Technology

[0002] In the tea processing, fermentation is the core process that determines the color, aroma, and taste of tea. Cabinet-type tea fermentation machines are one of the most widely used fermentation equipment. Cabinet-type tea fermentation machines mainly achieve tea fermentation through multiple static trays installed inside the cabinet. After withering and rolling, the tea leaves are evenly spread on each layer of static trays. Through the temperature and humidity control system built into the cabinet, the temperature and humidity inside the cabinet are controlled within a reasonable range. Under this environment, the tea polyphenols that seep out after the tea cells are broken undergo enzymatic oxidation under the catalysis of polyphenol oxidase, generating characteristic components such as theaflavins and thearubigins, thus completing the tea fermentation process.

[0003] In common cabinet-type tea fermentation machines, the tea leaves in the tray are always in a static, piled-up state. The tea layer has small pores and poor ventilation, which easily leads to a significant temperature difference between the surface of the tea leaves and the center of the pile. This makes it difficult to accurately control the temperature of the tea leaves, thus affecting the fermentation quality. Therefore, this application provides a tea fermentation machine and fermentation method that is easy to control the temperature to meet the requirements. Summary of the Invention

[0004] This invention provides a tea fermentation machine and fermentation method that are easy to control the temperature, in order to solve the problem that tea fermentation is always in a static pile state, and a significant temperature difference easily forms between the surface of the tea and the center of the pile, making it difficult to accurately control the temperature of the tea and thus affecting the fermentation quality of the tea.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A temperature-controlled tea fermentation machine includes a fermentation cabinet and also includes:

[0007] The dispersion mechanism includes multiple guide hoods fixed inside the fermentation tank, a cylinder rotatably connected inside the guide hood, ventilation holes on the cylinder, a partition fixed to the inner wall of the guide hood, a geared motor fixed to the side of the fermentation tank, the output end of the geared motor fixedly connected to the end of the cylinder, multiple levers fixed to the inner wall of the cylinder, a dispersion component installed inside the cylinder, an exhaust hood fixed to the side of the fermentation tank, the exhaust hood communicating with the guide hood, and a fan fixed inside the exhaust hood;

[0008] During fermentation, the cylinder uses a deflector to drop the tea leaves from a height, and a dispersing component is used to break up the falling tea leaves.

[0009] Preferably, the dispersing component includes a fixed frame fixed to the inner wall of the fermentation cabinet, a central rod fixed to the side of the fixed frame, the end of the central rod away from the fixed frame being rotatably connected to the side of the inner wall of the cylinder, a bracket fixed to the central rod, a spring fixed to the top of the bracket, a vibrating plate fixed to the top of the spring, a vibrating motor fixed to the bottom of the vibrating plate, a guide rod fixed to the bottom of the vibrating plate, the bottom of the guide rod movably passing through the bracket, and multiple dispersing structures provided on the vibrating plate. When the vibrating motor drives the vibrating plate to vibrate, the dispersing structures move up and down to disperse the falling tea leaves.

[0010] Preferably, the dispersion structure includes two square plates, with a vertical strip movably passing through the top of the vibrating plate, the square plates being positioned at the top of the vertical strip, and a limit block being fixed at the bottom of the vertical strip.

[0011] Preferably, multiple steel wire ropes are fixed to the opposite faces of the two square plates, a round bar is fixed to the top of the vibrating plate, a bent part is integrally formed at the bottom of the round bar, the bottom of the bent part is fixedly connected to the top of the vibrating plate, a protrusion is integrally formed on the round bar near the position of the steel wire rope, the square plate is rotatably connected to the top of the vertical bar, a wear-resistant sleeve is fixedly sleeved on the steel wire rope, the protrusion squeezes the wear-resistant sleeve when the square plate moves up and down, and rubber sheets are fixed to the opposite sides of the square plates, the bottom of the rubber sheets is in contact with the top of the vibrating plate.

[0012] Preferably, a spring sheet is fixed on the rubber sheet, and the side of the spring sheet is fixedly connected to the side of the square plate.

[0013] Preferably, the side of the square plate is inlaid with a connector, which is fixed to the end of the wire rope.

[0014] Preferably, the top of the square plate is integrally formed with a thickened part, and a notch is provided on the thickened part. The top of the thickened part and the inner wall of the notch are both upwardly curved surfaces.

[0015] Preferably, both of the square plates have a dispersion strip fixed on their opposite sides, and the dispersion strip is wavy.

[0016] Preferably, the side of the dial plate closest to the axis of rotation of the cylinder has an integrally formed inclined portion.

[0017] A temperature-controlled tea fermentation method, applied to the aforementioned temperature-controlled tea fermentation machine, includes the following steps:

[0018] S1: Place the tea leaves into the cylinder, and moisture and hot air enter the cylinder through the vent.

[0019] S2: The geared motor drives the cylinder to rotate, and the cylinder drives the paddle to move the tea leaves while causing the tea leaves to fall from a height.

[0020] S3: The tea leaves fall onto the vibrating plate, and the vibrating plate and square plate break up the tea leaves.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] In the above scheme, by setting up a cylinder, a deflector, and a dispersing component, tea leaves are placed inside the cylinder. Moisture and hot air are guided through the guide hood and enter the cylinder through the vent. The geared motor drives the cylinder to rotate, and the cylinder drives the deflector to move the tea leaves while causing them to fall from a height. The dispersing component is used to disperse the falling tea leaves, so that the tea leaves can fully contact the moisture and prevent the tea leaves from piling up. This achieves accurate and reliable temperature control of the tea leaves and effectively improves the quality of tea fermentation.

[0023] By setting up a vibrating plate and a vibrating motor, the vibrating motor drives the vibrating plate to vibrate, and the falling tea leaves fall onto the vibrating plate, where the vibrating plate initially breaks them up, preventing the tea leaves from clumping together after kneading, and allowing the tea leaves to come into more comprehensive and sufficient contact with moisture, thereby further improving the fermentation quality of the tea.

[0024] By setting up a square plate, vertical bars, and limiting blocks, when the vibrating plate vibrates upward, it drives the square plate to move upward, which in turn drives the vertical bars to move upward. The limiting blocks are used to limit the upward movement distance of the square plate. When the vibrating plate vibrates downward and comes into contact with the limiting blocks, the vibrating plate drives the square plate to move downward through the limiting blocks. The up-and-down movement of the square plate further improves the ability to disperse tea leaves.

[0025] By incorporating steel wire ropes, protrusions, wear-resistant sleeves, and rubber sheets, the rubber sheets are fixed to both sides of the square plate. These rubber sheets provide elastic support to the plate and shield the area between the bottom of the square plate and the vibrating plate, preventing tea leaves from entering this area and affecting the vertical movement and rotation of the plate. They also prevent the plate from pressing down on the tea leaves and causing them to clump again when moving downwards. During the vertical movement of the square plate, the steel wire ropes and rubber sheets move synchronously up and down. The rubber sheets, under their own elasticity, remain in contact with the top of the vibrating plate. Furthermore, when the wear-resistant sleeves on the steel wire ropes pass the protrusions on the round bars, the steel wire ropes bend and deform, causing the two square plates to rotate towards each other. The square plates can also rotate during their vertical movement, increasing the contact between the plate and the tea leaves, further enhancing the ability to disperse the tea.

[0026] By incorporating a bend at the bottom of the round strip, an obtuse angle is formed between the bend and the top of the vibrating plate, preventing tea leaves from accumulating at the connection between the round strip and the vibrating plate and ensuring that the tea leaves slide steadily off the vibrating plate.

[0027] By setting up springs, the springs are used to improve the elasticity of the rubber sheet, enhance the elastic support capacity of the square plate, and rely on their own elasticity to make the bottom of the rubber sheet stably fit with the top of the vibrating plate. At the same time, after the square plate rotates, the springs on the corresponding side are squeezed. After the protrusion separates from the wear-resistant sleeve, the springs on that side assist the square plate in resetting.

[0028] By setting a connector, the contact area between the wire rope and the square plate is increased, preventing the wire rope from breaking at the connection point with the square plate when under stress, and thus improving the service life of the wire rope.

[0029] By incorporating a thickened section and a notch, the thickened section, located at the top of the square plate, prevents sharp edges from damaging the tea leaves. Meanwhile, the notch, situated on the thickened section, allows the tea leaves to come into contact with its uneven top as they fall, further enhancing the ability to disperse the tea.

[0030] By setting up dispersion strips, the dispersion strips move simultaneously when the square plate moves up and down and rotates. The dispersion strips are used to disperse the tea leaves between two adjacent dispersion structures, and the dispersion strips further enhance the ability to disperse the tea leaves, so that the tea leaves can come into even and full contact with the water vapor.

[0031] By incorporating an inclined section, the amount of upward rotation of the tea leaves driven by the deflector is increased, allowing more tea leaves to come into contact with the dispersing mechanism. Simultaneously, the tea leaves fall from a higher position, increasing the impact force between the tea leaves and the dispersing mechanism, thus aiding in the dispersion of the tea leaves.

However, this is only for illustrative purposes and is not intended to limit the present invention to the specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0046] The following is a detailed description of a temperature-controlled tea fermentation machine and its fermentation method provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0047] like Figures 1-12As shown, an embodiment of the present invention provides a tea fermentation machine with easy temperature control, including a fermentation cabinet 1 and a dispersion mechanism 2. The dispersion mechanism 2 includes multiple guide hoods 3 fixed inside the fermentation cabinet 1. A cylinder 4 is rotatably connected inside the guide hood 3. The cylinder 4 has ventilation holes. A partition 29 is fixed to the inner wall of the guide hood 3, dividing the interior of the guide hood 3 into an air intake zone and an air exhaust zone. A reduction motor 5 is fixed to the side of the fermentation cabinet 1. The output end of the reduction motor 5 is fixedly connected to the end of the cylinder 4. Multiple levers 6 are fixed to the inner wall of the cylinder 4. A dispersion assembly is provided inside the cylinder 4. The dispersion assembly includes a fixing frame fixed to the inner wall of the fermentation cabinet 1. A central rod 8 is fixed to the side of the fixed frame. The end of the central rod 8 away from the fixed frame is rotatably connected to the side of the inner wall of the cylinder 4. A bracket 10 is fixed on the central rod 8. A spring 11 is fixed to the top of the bracket 10. A vibrating plate 12 is fixed to the top of the spring 11. A vibration motor 9 is fixed to the bottom of the vibrating plate 12. A guide rod is fixed to the bottom of the vibrating plate 12. The bottom of the guide rod moves through the bracket 10. Multiple sets of dispersion structures are provided on the vibrating plate 12. During fermentation, the cylinder 4 drives the tea leaves to fall from a height through the deflector 6. The dispersion components are used to disperse the falling tea leaves, so that the water vapor and hot air generated by the fermentation cabinet 1 enter the cylinder 4 through the air inlet area and the vent.

[0048] like Figures 6-8 As shown in this embodiment, when the vibration motor 9 drives the vibration plate 12 to vibrate, the dispersing structure moves up and down to break up the falling tea leaves. The central rod 8 provides stable support for the support 10, and the spring 11 provides elastic support for the vibration plate 12. Together with the vibration motor 9, continuous vibration is achieved. The guide rod restricts the vibration plate 12 to vibrate only in the vertical direction, thereby improving vibration stability. The vibration plate 12 receives and breaks up the falling tea leaves, and the dispersing structure moves up and down with it to break up the tea leaves together, preventing clumping and allowing the tea leaves to come into more comprehensive contact with moisture, thus improving the uniformity of fermentation.

[0049] like Figures 1-6 as well as Figure 12 As shown in this embodiment, an exhaust hood 27 is fixed on the side of the fermentation cabinet 1. The exhaust hood 27 is connected to the guide hood 3, and a fan 28 is fixed inside the exhaust hood 27. At the same time, the fermentation gas enters the exhaust hood 27 through the exhaust area and is discharged by the fan 28. The reduction motor 5 drives the cylinder 4 to rotate, and the deflector 6 rotates synchronously with it. This not only prevents the tea leaves from piling up, but also drives the tea leaves to fall from a height. In conjunction with the dispersing component, the tea leaves are dispersed, so that the tea leaves can fully contact the water vapor, achieve precise temperature control, and improve the quality of tea fermentation.

[0050] like Figures 4-6As shown in this embodiment, the side of the paddle plate 6 closest to the rotation axis of the cylinder 4 is integrally formed with an inclined part 7. The inclined part 7 increases the load capacity of the paddle plate 6 in driving the tea leaves to rotate upward, so that more tea leaves are carried to a higher position and fall, increasing the probability of contact with the dispersing components and the falling height, increasing the impact force, enhancing the auxiliary dispersing effect, making the tea leaves disperse more fully, and further improving the fermentation temperature control accuracy and fermentation quality.

[0051] like Figures 8-11 As shown in this embodiment, the dispersing structure includes two square plates 13. A vertical strip 14 is movably passed through the top of the vibrating plate 12. The square plate 13 is set on the top of the vertical strip 14. A limit block 15 is fixed at the bottom of the vertical strip 14. The vertical strip 14 supports the square plate 13, so that it moves synchronously with the vibrating plate 12. The limit block 15 restricts the maximum distance that the square plate 13 can move upward to prevent it from leaving the working area. When the vibrating plate 12 vibrates upward, it drives the square plate 13 to move upward. When it vibrates downward, it drives the square plate 13 to move downward through the limit block 15. The up and down movement of the square plate 13 disperses the tea leaves, thereby improving the dispersing effect of the tea leaves.

[0052] like Figure 9 and Figure 11 As shown in this embodiment, multiple steel wire ropes 18 are fixed to the opposite faces of the two square plates 13. A round bar 21 is fixed to the top of the vibrating plate 12. A bent portion 22 is integrally formed at the bottom of the round bar 21. The bottom of the bent portion 22 is fixedly connected to the top of the vibrating plate 12. A protrusion 23 is integrally formed on the round bar 21 near the position of the steel wire ropes 18. The square plates 13 are rotatably connected to the top of the vertical bars 14. The square plates 13 are rotatably connected to the vertical bars 14 via a rotating shaft. Wear-resistant sleeves 20 are fixedly sleeved on the steel wire ropes 18. When the square plates 13 move up and down, the protrusions 23 squeeze the wear-resistant sleeves 20. The opposite sides of the square plates 13 are all... A rubber sheet 16 is fixed in place, with its bottom fitting against the top of the vibrating plate 12. The bent part 22 forms an obtuse angle with the vibrating plate 12 to prevent tea leaves from accumulating at the connection between the round strip 21 and the vibrating plate 12, ensuring that the tea leaves slide smoothly. When the square plate 13 moves up and down, the protrusion 23 squeezes the wear-resistant sleeve 20, causing the steel wire rope 18 to bend and drive the two square plates 13 to rotate towards each other, increasing the chance of contact with the tea leaves. The rubber sheet 16 provides elastic support to the square plate 13 and at the same time blocks the gap between the bottom of the square plate 13 and the vibrating plate 12, preventing tea leaves from entering and affecting the movement, and avoiding secondary clumping caused by pressing down on the tea leaves.

[0053] A spring sheet 17 is fixed on the rubber sheet 16. The side of the spring sheet 17 is fixedly connected to the side of the square plate 13. The spring sheet 17 enhances the elastic support of the rubber sheet 16, so that the bottom of the rubber sheet 16 is always stably attached to the top of the vibrating plate 12. When the square plate 13 rotates and squeezes the spring sheet 17, the spring sheet 17 relies on its own elasticity to assist the square plate 13 to quickly return to its original position, ensuring that the square plate 13 can continuously and stably move up and down and rotate, further improving the tea-dispersing effect.

[0054] like Figure 11 As shown in this embodiment, a connector 19 is embedded on the side of the square plate 13. The connector 19 is fixed to the end of the wire rope 18. The connector 19 increases the connection area between the wire rope 18 and the square plate 13, disperses the local stress when under force, prevents the connection between the wire rope 18 and the square plate 13 from breaking, improves the service life of the wire rope 18, and ensures that the rotation of the square plate 13 is stable and reliable.

[0055] like Figures 9-11 As shown in this embodiment, the top of the square plate 13 is integrally formed with a thickened part 25, and a notch 26 is provided on the thickened part 25. The top of the thickened part 25 and the inner wall of the notch 26 are both upward curved surfaces. The thickened part 25 eliminates the sharp edges of the top of the square plate 13, avoids damage to the tea leaves when impacted, and ensures the appearance of the tea leaves. The notch 26 and the curved surface of the thickened part 25 form an uneven dispersing surface, which further improves the dispersing effect, makes the tea leaves disperse more evenly, ensures full contact with moisture, and improves the consistency of fermentation.

[0056] like Figure 9 and Figure 11 As shown in this embodiment, both square plates 13 have a dispersion strip 24 fixed on their opposite sides. The dispersion strip 24 is wavy and moves up and down and rotates synchronously with the square plates 13 to supplement and disperse the tea leaves between the two adjacent dispersion structures, eliminate the dispersion blind zone, and increase the contact area and impact probability with the tea leaves, further improving the dispersion uniformity and ensuring that all tea leaves can fully contact the hot air and water vapor to stabilize the fermentation quality.

[0057] A temperature-controlled tea fermentation method, applied to the aforementioned temperature-controlled tea fermentation machine, includes the following steps:

[0058] S1: Place the tea leaves into the cylinder 4, and the moisture and hot air enter the cylinder 4 through the vent.

[0059] S2: The geared motor 5 drives the cylinder 4 to rotate, and the cylinder 4 drives the paddle plate 6 to paddle the tea leaves while causing the tea leaves to fall from a height;

[0060] S3: The tea leaves fall onto the vibrating plate 12, and the vibrating plate 12 and the square plate 13 break up the tea leaves.

[0061] Working principle: During fermentation, tea leaves are placed in cylinder 4. The water vapor and hot air generated by fermentation cabinet 1 are guided by the guide hood 3 and enter the interior of cylinder 4 through the air vent on cylinder 4. The partition 29 inside the guide hood 3 is used to separate the internal space of the guide hood 3, so that the right half of the guide hood 3 is used for air intake and the left half is used for air exhaust.

[0062] The geared motor 5 on the side of the fermentation cabinet 1 drives the cylinder 4 to rotate. Multiple deflectors 6 on the inner wall of the cylinder 4 rotate synchronously with the cylinder 4. They can both deflect the tea leaves to prevent them from piling up and drive the tea leaves to fall from a height. The dispersing component inside the cylinder 4 disperses the falling tea leaves. At the same time, the gas after fermentation enters the exhaust hood 27 through the guide hood 3 and is discharged by the fan 28 to ensure a stable fermentation environment. The side of the deflector 6 closest to the rotation axis of the cylinder 4 has an integrally formed inclined part 7. The inclined part 7 can increase the amount of tea leaves that the deflector 6 drives to rotate upward, allowing more tea leaves to come into contact with the dispersing component. At the same time, it can make the tea leaves fall from a higher height, increasing the impact force between the tea leaves and the dispersing component, assisting in the dispersion of the tea leaves, and further improving the dispersing effect.

[0063] The bracket 10 is fixed on the central rod 8. The spring 11 at the top of the bracket 10 provides elastic support for the vibrating plate 12. The guide rod at the bottom of the vibrating plate 12 passes through the bracket 10 and guides the vibration of the vibrating plate 12, so that the vibrating plate 12 vibrates stably in the vertical direction. The vibration motor 9 is started to drive the vibrating plate 12 to vibrate up and down. The falling tea leaves fall to the vibrating plate 12. When the vibrating plate 12 vibrates upward, it drives the square plate 13 to move upward synchronously. When the vibrating plate 12 vibrates downward and contacts the limiting block 15, the limiting block 15 drives the vertical bar 14 and the square plate 13 to move downward. The up and down movement of the square plate 13 can further improve the ability to disperse the tea leaves and prevent the tea leaves from accumulating on the vibrating plate 12. The dispersed tea leaves fall from the vibrating plate 12 to the bottom of the inner wall of the cylinder 4.

[0064] The bottom of the round strip 21 is integrally formed with a bent part 22. The bent part 22 and the top of the vibrating plate 12 form an obtuse angle, which can prevent tea leaves from accumulating at the connection between the round strip 21 and the vibrating plate 12, ensuring that the tea leaves slide stably off the vibrating plate 12 and avoid affecting the dispersing effect.

[0065] When the square plate 13 moves up and down with the vibrating plate 12, the wear-resistant sleeve 20 on the wire rope 18 will pass through the protrusion 23. The protrusion 23 squeezes the wear-resistant sleeve 20, causing the wire rope 18 to bend and deform, which in turn drives the two square plates 13 to rotate towards each other. The square plate 13 can also rotate while moving up and down, which increases the contact opportunity between the square plate 13 and the tea leaves, and further improves the ability to disperse the tea leaves.

[0066] Rubber sheets 16 are fixed on opposite sides of the square plate 13. The bottom of the rubber sheet 16 is in contact with the top of the vibrating plate 12. The rubber sheet 16 is used to provide elastic support for the square plate 13 and at the same time to cover the area between the bottom of the square plate 13 and the vibrating plate 12, preventing tea leaves from entering the area and affecting the up-down movement and rotation of the square plate 13. It can also prevent the square plate 13 from pressing down on the tea leaves when it moves downward, preventing the tea leaves from clumping together again. The spring sheet 17 fixed on the rubber sheet 16 can improve the elasticity of the rubber sheet 16 and enhance the elastic support capacity of the square plate 13. The spring sheet 17 relies on its own elasticity to keep the bottom of the rubber sheet 16 in stable contact with the top of the vibrating plate 12. At the same time, when the square plate 13 rotates and squeezes the spring sheet 17 and the rubber sheet 16 on the corresponding side, after the protrusion 23 separates from the wear-resistant sleeve 20, the spring sheet 17 can assist the square plate 13 to quickly return to its original position.

[0067] The top of the square plate 13 is integrally formed with a thickened part 25. The thickened part 25 can prevent the sharp edges of the top of the square plate 13 from damaging the tea leaves and protect the appearance of the tea leaves. The thickened part 25 has a notch 26, and the top of the thickened part 25 and the inner wall of the notch 26 are both upward curved surfaces. When the tea leaves fall, they will come into contact with the uneven surface of the thickened part 25, which will further improve the ability to disperse the tea leaves and make the tea leaves disperse more evenly. When the square plate 13 moves up and down and rotates, it will drive the dispersing strip 24 to move synchronously. The dispersing strip 24 is used to disperse the tea leaves between two adjacent sets of dispersing structures, further improving the dispersing effect and ensuring that all tea leaves can come into contact with moisture evenly and fully, thus ensuring the stability of the tea fermentation quality.

[0068] After the tea leaves have fermented, open the door of the fermentation cabinet 1, and the geared motor 5 will drive the cylinder 4 to rotate in the opposite direction. The fermented tea leaves will be discharged from the end of the cylinder 4 by the inclined baffle 6 inside the cylinder 4. The tea leaves can then be collected using a container.

[0069] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
