Description

Technical Field

[0001] This invention relates to the field of tea production equipment technology, and in particular to a fermentation device for tea production with precise temperature control. Background Technology

[0002] Fermentation in tea processing aims to alter the composition of tea leaves through the action of microorganisms, enzymes, and oxidation, resulting in unique flavors, colors, and aromas, such as the red liquor and leaves of black tea, and the rich aroma of oolong tea. Fermentation is generally carried out using naturally occurring microorganisms (such as yeast and mold) or artificially added fermenting agents (such as specific probiotics). Fermentation can also be assisted by controlling temperature and humidity using a fermentation machine. After the fresh leaves are spread out and subjected to fixation (for some tea types), under suitable temperature and humidity, the tea polyphenols in the tea leaves oxidize and polymerize, chlorophyll degrades, and amino acids and aromatic substances are generated. Microorganisms and enzymes catalyze the transformation of substances, such as the decomposition of proteins into amino acids and polysaccharides into monosaccharides, forming the characteristics of different tea types. The general process flow is: fresh leaf processing → temperature and humidity control (25-35℃, humidity 70%-90%) → tea leaves are left to stand or turned in the fermentation equipment → the fermentation degree is monitored periodically → the process is terminated after the target is reached (e.g., drying).

[0003] The existing publication number is CN119014468B. This invention relates to the field of tea fermentation technology, and discloses a tea processing fermentation tank and process. The tea processing fermentation tank includes a base, a fermentation tank body disposed on top of the base, a stirring assembly disposed within the fermentation tank body, and an auxiliary mounting assembly disposed on the fermentation tank body. The auxiliary mounting assembly specifically includes a mounting port disposed on the surface of the fermentation tank body. This tea processing fermentation tank, by setting multiple placement components, disperses the tea leaves, preventing excessive accumulation and facilitating thorough stirring. This allows for sufficient contact with oxygen during fermentation, which is beneficial for improving tea quality. Furthermore, by installing the stirring assembly within a mounting plate, after fermentation, the mounting plate can be removed from the fermentation tank body simply by rotating the extension rod and mounting rod, facilitating observation and cleaning of the stirring assembly. Moreover, cleaning only requires removing and cleaning the placement components, eliminating the need to clean the entire device.

[0004] However, existing tea fermentation machines generally require stirring the tea leaves to ensure uniform fermentation. But because many tea leaves that have undergone fixation are quite brittle, the stirring paddle can easily crush the tea leaves when they come into contact with the tea leaves, thus affecting the processing quality of the tea.

[0016] Beneficial effects

[0017] This invention incorporates an absorption mechanism. A uniformly driven motor rotates a uniformly dispersing shaft, which in turn rotates a fermentation support plate. This rotation ensures uniform contact between the tea leaves and oxygen and moisture, improving the uniformity of tea fermentation. Simultaneously, a heating element controls the temperature inside the fermentation machine, and a humidifying nozzle controls the humidity, ensuring a suitable fermentation environment. For aerobic teas such as black tea, oolong tea, and some yellow teas like Huangda tea, an aeration adsorption fan is activated. This fan replenishes oxygen to the fermentation machine through the aeration absorption component. After fermentation, the aeration adsorption fan is reversed, absorbing moisture from the fermentation machine and facilitating tea leaf removal by workers.

[0018] This invention utilizes a uniform fermentation mechanism. Rotating the thickness adjustment screw causes the fermentation limiting component to move up and down, thus controlling the size of the opening on the outer side of the fermentation support plate. Then, opening the thickness control component causes the thickness control slider to move up and down, which in turn causes the thickness control plate to move up and down, thus controlling the thickness of the tea leaves spread.

[0019] This invention utilizes a uniform fermentation mechanism. A uniform drive motor drives a reverse drive gear, which in turn drives a reverse transmission gear, which in turn drives a reverse transmission shaft, which in turn drives a uniform dispersion shaft, which in turn drives a fermentation support plate. This rotation of the fermentation support plate moves relative to a thickness control plate, allowing the thickness control plate to spread the tea leaves. Excess tea leaves fall downwards through fermentation limiting components, achieving effective spreading and control of the tea leaves after spreading, thus improving the uniformity of tea fermentation. Simultaneously, a second layer of protection... The magnetic adhesive block and the first anti-sticking magnetic block are magnetically connected, which fixes the position of the thickness control plate and the anti-sticking lever. The anti-sticking lever moves relative to the fermentation support tray, and the tea leaves inside the fermentation support tray are pushed by the anti-sticking lever, preventing the tea leaves from sticking to the fermentation support tray. At the same time, the anti-sticking vibrating plate is squeezed and deformed when it passes the anti-sticking protrusion. After moving past the position of the anti-sticking protrusion, the anti-sticking vibrating plate returns to its original position and generates elasticity, causing the tea leaves to resonate slightly. This ensures the separation of the tea leaves, avoids damage to the tea leaves, protects the tea leaves, ensures the integrity of the tea leaves, and improves the processing quality of the tea leaves.

[0044] The specific usage and function of this embodiment are as follows: When fermenting tea leaves, after placing the tea leaves on the fermentation support tray 6, rotate the thickness adjustment screw 408. The rotation of the thickness adjustment screw 408 causes the fermentation limiting component 407 to move up and down. The up and down movement of the fermentation limiting component 407 controls the size of the opening on the outer side of the fermentation support tray 6. Then, open the thickness control component 414. The thickness control component 414 causes the thickness control slider 413 to move up and down. The up and down movement of the thickness control slider 413 causes the thickness control plate 415 to move up and down. The up and down movement of the thickness control plate 415 controls the thickness of the tea leaf spreading. Turn on the uniform drive motor. 4. The uniform drive motor 4 drives the reverse drive gear 403 to rotate. The rotation of the reverse drive gear 403 drives the reverse transmission gear 405 to rotate. The rotation of the reverse transmission gear 405 drives the reverse transmission shaft 404 to rotate. The rotation of the reverse transmission shaft 404 drives the uniform dispersion shaft 5 to rotate. The rotation of the uniform dispersion shaft 5 drives the fermentation support plate 6 to rotate. The rotation of the fermentation support plate 6 moves relative to the thickness control plate 415. The thickness control plate 415 spreads the tea leaves. Excess tea leaves fall downwards through the fermentation limiting component 407, realizing the spreading of the tea leaves and controlling the spread of the tea leaves. This improves the uniformity of tea fermentation. At the same time, the second anti-fouling mechanism is used. The magnetically attached block 417 is magnetically connected to the first anti-sticking magnetic block 416, which fixes the thickness control plate 415 and the anti-sticking lever 410 in a relatively fixed position. The anti-sticking lever 410 moves relative to the fermentation support plate 6, and the tea leaves inside the fermentation support plate 6 are pushed by the anti-sticking lever 410, preventing the tea leaves from sticking to the fermentation support plate 6. At the same time, the anti-sticking vibrating plate 411 is squeezed and deformed when it passes the anti-sticking protrusion 412. After moving past the position of the anti-sticking protrusion 412, the anti-sticking vibrating plate 411 returns to its original position and generates elasticity, causing the tea leaves to resonate slightly, ensuring the separation of the tea leaves and avoiding damage to the tea leaves, thus achieving the preservation of the tea leaves. This process protects the tea leaves, ensuring their integrity and improving processing quality. Under centrifugal force, the tea leaves tumble as they pass through the tumbling guide trough 409. After fermentation for a period of time, the forward and reverse drive component 402 is activated. The push rod of the forward and reverse drive component 402 moves up and down, driving the uniform drive slider 401 to move up and down. The uniform drive slider 401 moves up and down, driving the reverse drive gear 403 to move up and down. The reverse drive gear 403 alternately meshes with the reverse transmission gear 405, causing the fermentation support plate 6 to rotate alternately in both directions. This avoids the fermentation support plate 6 rotating in the same direction for a long time and reduces friction damage between the inner wall of the fermentation support plate 6 and the tea leaves.
