AI Technical Summary
The fermentation process of Lao Ying Tea suffers from problems such as flavor loss, uneven fermentation, and poor product stability due to fluctuations in environmental conditions. Existing equipment is difficult to achieve precise monitoring and control, especially during mixed fermentation, where uneven oxygen distribution leads to an imbalance in microbial activity.
The fermentation chamber is equipped with dual oxygen concentration sensors to monitor the top and bottom. Combined with temperature and humidity sensors, oxygen supply, temperature and humidity are adjusted in real time. The control panel is used to adjust components such as heating wires, air coolers and spray nozzles to achieve closed-loop control.
To ensure that Eagle Tea is always in the optimal fermentation environment, we can reduce the loss of characteristic flavors, improve the precision of parameter control, and enhance product stability and flavor integration.

Description
TECHNICAL FIELD
[0001] The present application relates to the field of food technology, in particular to a production method and equipment of eagle tea. BACKGROUND
[0002] As a characteristic plant of medicine and food in China, eagle tea is rich in active ingredients such as flavonoids and amino acids, and has a unique camphor fragrance and refreshing taste. It has high development value in the fields of drinks and health products. Fermentation is a key link in the production and processing of eagle tea. Through microbial metabolism and enzymatic reaction, the bitterness and astringency of eagle tea can be improved, and the flavor coordination can be improved. Especially when eagle tea is mixed with other tea (such as black tea, green tea, etc.) for fermentation, flavor complementation can be achieved, and product diversity can be expanded. However, there are still many technical bottlenecks in the current fermentation production of eagle tea. On the one hand, the raw material of eagle tea is the tender leaves of plants in the Lauraceae family, which is rich in volatile terpenes (which gives camphor fragrance), and the leaves are thin, high in water content, and poor in material stability. The characteristic flavor is easily lost due to fluctuations in environmental conditions during fermentation. At the same time, when mixed with other tea for fermentation, the composition difference (such as tea polyphenol, amino acid ratio) and metabolic characteristics of the two raw materials easily cause fermentation process imbalance, resulting in poor flavor fusion.
[0003] On the other hand, the existing fermentation technology lacks control accuracy for key environmental parameters: temperature and humidity control relies on empirical operation, lacks dynamic adjustment mechanism for mixed materials, and is prone to problems such as local over-wetting and uneven temperature distribution, leading to unbalanced microbial activity and inconsistent fermentation degree. Oxygen concentration is a key factor affecting microbial metabolism. The existing equipment cannot accurately monitor and uniformly supply oxygen in the fermentation tank (such as the top and bottom). Local anaerobic or excessive oxidation often occurs due to differences in oxygen distribution, affecting the retention of active ingredients. During mixed fermentation, local environmental differences caused by material accumulation (such as different fermentation trays and different areas of the same fermentation tray) are difficult to eliminate, and the degree of automation is low, relying on manual stirring or humidification. Not only is the efficiency low, but also errors are easily introduced due to human intervention, resulting in poor batch stability of the product and difficulty in meeting the needs of large-scale production. SUMMARY

When the humidity data of the target mixed tea in the adjacent fermentation tray of the target fermentation tray is greater than the preset humidity threshold range, the target mixed tea in the adjacent fermentation tray is stirred, and it is determined whether the spraying amount and the rotation speed of the fermentation tray are adjusted.
[0012] In some embodiments, when the humidity data of the target mixed tea in the adjacent fermentation tray of the target fermentation tray is greater than the preset humidity threshold range, the target mixed tea in the adjacent fermentation tray is stirred, and it is determined whether the spraying amount and the rotation speed of the fermentation tray are adjusted, comprising: When the humidity data of the target mixed tea in the adjacent fermentation tray of the target fermentation tray is within the preset humidity threshold range after the target mixed tea in the adjacent fermentation tray is stirred, the spraying amount and the rotation speed of the fermentation tray are not adjusted.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0025] Referring to Figures 1-5 As shown in the first embodiment, the production method of eagle tea according to the embodiments of the present application comprises the following steps: S1, mixing the withered and rolled eagle tea and black tea to obtain target mixed tea; S2, evenly laying the target mixed tea in a plurality of fermentation trays, and vertically and spacedly arranging the plurality of fermentation trays in the interior of a fermentation box; S3, acquiring humidity data and temperature data of the target mixed tea in the interior of each fermentation tray, and acquiring oxygen concentration data in the interior of the fermentation box; S4, adjusting the working state of the fermentation box according to the humidity data, temperature data and oxygen concentration data.
[0026] In some embodiments, when the working state of the fermentation box is adjusted according to the humidity data, temperature data and oxygen concentration data in the step S4, it comprises: presetting an oxygen concentration threshold range required by the target mixed tea during fermentation; When the oxygen concentration data is greater than or less than the oxygen concentration threshold range, oxygen is filled into the interior of the fermentation box; Otherwise, no oxygen is filled into the interior of the fermentation box.
[0027] In some embodiments, when the oxygen concentration data is greater than or less than the oxygen concentration threshold range, oxygen is filled into the interior of the fermentation box, which comprises: When the oxygen concentration data near the top of the fermentation box is less than or greater than the oxygen concentration threshold range, and the oxygen concentration data near the bottom of the fermentation box is less than or greater than the oxygen concentration threshold range, oxygen continues to be filled into the interior of the fermentation box. when the oxygen concentration data near the top of the fermentation tank inside the fermentation tank is equal to the oxygen concentration threshold range, and the oxygen concentration data near the bottom of the fermentation tank inside the fermentation tank is less than or greater than the oxygen concentration threshold range, continue to fill oxygen into the fermentation tank inside; when the oxygen concentration data near the top of the fermentation tank inside the fermentation tank is less than or greater than the oxygen concentration threshold range, and the oxygen concentration data near the bottom of the fermentation tank inside the fermentation tank is equal to the oxygen concentration threshold range, continue to fill oxygen into the fermentation tank inside; when the oxygen concentration data near the top of the fermentation tank inside the fermentation tank is equal to the oxygen concentration threshold range, and the oxygen concentration data near the bottom of the fermentation tank inside the fermentation tank is equal to the oxygen concentration threshold range, do not fill oxygen into the fermentation tank inside.
[0028] In some embodiments, when the oxygen concentration data near the top of the fermentation tank inside the fermentation tank is equal to the oxygen concentration threshold range, and the oxygen concentration data near the bottom of the fermentation tank inside the fermentation tank is equal to the oxygen concentration threshold range, do not fill oxygen into the fermentation tank inside, including: preset a waiting threshold time range; when the oxygen concentration data near the top of the fermentation tank inside the fermentation tank is equal to the oxygen concentration threshold range, and the oxygen concentration data near the bottom of the fermentation tank inside the fermentation tank is equal to the oxygen concentration threshold range, for the first time, within the waiting threshold time, the oxygen concentration data near the top of the fermentation tank inside the fermentation tank is equal to the oxygen concentration threshold range, and the oxygen concentration data near the bottom of the fermentation tank inside the fermentation tank is equal to the oxygen concentration threshold range, do not fill oxygen into the fermentation tank inside; when the oxygen concentration data near the top of the fermentation tank inside the fermentation tank is equal to the oxygen concentration threshold range, and the oxygen concentration data near the bottom of the fermentation tank inside the fermentation tank is equal to the oxygen concentration threshold range, for the first time, within the waiting threshold time, the oxygen concentration data near the top of the fermentation tank inside the fermentation tank is less than or greater than the oxygen concentration threshold range, and / or the oxygen concentration data near the bottom of the fermentation tank inside the fermentation tank is less than or greater than the oxygen concentration threshold range, continue to fill oxygen into the fermentation tank inside.
[0029] It should be understood that the top + bottom double-point oxygen concentration sensor is arranged in the fermentation tank, which solves the problem that the traditional single-point monitoring cannot reflect the oxygen gradient distribution in the tank. Because the material accumulation during the fermentation process can cause uneven oxygen diffusion (the top is easy to enrich / consume fast, and the bottom is relatively lagging), the double-point monitoring can capture the oxygen concentration difference in the vertical direction.
[0030] If both top and bottom oxygen concentrations deviate from the threshold range (too high / too low), it indicates that the overall environment needs intervention → continue oxygenation.
[0031] If only one side (top or bottom) is abnormal, and the other side is normal, it indicates that the local environment is not balanced → continue oxygenation to eliminate the gradient difference.
[0032] Only when both top and bottom oxygen concentrations are within the threshold range, it is determined to be a stable state → stop oxygenation.
[0033] Introduce time dimension to verify stability: after detecting that both top / bottom oxygen concentrations meet the standard for the first time, it needs to maintain this state for more than a preset "waiting threshold time" (e.g. 5 minutes).
[0034] If it continues to meet the standard within this time, it is confirmed that the environment is stable → stop oxygenation; if either sensor deviates from the threshold again, restart the oxygenation process.
[0035] In some embodiments, the step S4 of adjusting the working state of the fermentation tank according to the humidity data, temperature data and oxygen concentration data further comprises: When the temperature data is less than a preset temperature threshold range, the temperature inside the fermentation tank is raised; When the temperature data is greater than a preset temperature threshold range, the temperature inside the fermentation tank is lowered; When the temperature data is equal to a preset temperature threshold range, the temperature inside the fermentation tank is not adjusted.
[0036] In some embodiments, the step S4 of adjusting the working state of the fermentation tank according to the humidity data, temperature data and oxygen concentration data further comprises: When the humidity data of the target mixed tea inside the fermentation tray is less than a preset humidity threshold range, the target mixed tea inside the fermentation tray is sprayed for humidification; When the humidity data of the target mixed tea inside the fermentation tray is greater than a preset humidity threshold range, the target mixed tea inside the fermentation tray is stirred; When the humidity data of the target mixed tea inside the fermentation tray is equal to a preset humidity threshold range, the target mixed tea inside the fermentation tray is not adjusted.
[0037] In some embodiments, when the humidity data of the target mixed tea inside the fermentation tray is less than a preset humidity threshold range, the target mixed tea inside the fermentation tray is sprayed for humidification, comprising: When the target mixed tea inside the target fermentation tray is sprayed for humidification, it is judged whether the humidity data of the target mixed tea inside the adjacent fermentation tray of the target fermentation tray is within a preset humidity threshold range; When the humidity data of the target mixed tea in the adjacent fermentation tray of the target fermentation tray is within the preset humidity threshold range, the water spraying and humidifying of the target mixed tea in the target fermentation tray is continued until the humidity data of the target mixed tea in the target fermentation tray is within the preset humidity threshold range, and the water spraying and humidifying is stopped. When the humidity data of the target mixed tea in the adjacent fermentation tray of the target fermentation tray is greater than the preset humidity threshold range, the target mixed tea in the adjacent fermentation tray is stirred, and it is judged whether the water spraying amount and the rotation speed of the fermentation tray are adjusted.
[0038] In some embodiments, when the humidity data of the target mixed tea in the adjacent fermentation tray of the target fermentation tray is greater than the preset humidity threshold range, the target mixed tea in the adjacent fermentation tray is stirred, and it is judged whether the water spraying amount and the rotation speed of the fermentation tray are adjusted, comprising: When the humidity data of the target mixed tea in the adjacent fermentation tray of the target fermentation tray is within the preset humidity threshold range after the target mixed tea in the adjacent fermentation tray is stirred, the water spraying amount and the rotation speed of the fermentation tray are not adjusted. When the humidity data of the target mixed tea in the adjacent fermentation tray of the target fermentation tray is greater than the preset humidity threshold range after the target mixed tea in the adjacent fermentation tray is stirred, the water spraying amount and the rotation speed of the fermentation tray are adjusted.
[0039] In some embodiments, when the humidity data of the target mixed tea in the adjacent fermentation tray of the target fermentation tray is greater than the preset humidity threshold range after the target mixed tea in the adjacent fermentation tray is stirred, the water spraying amount and the rotation speed of the fermentation tray are adjusted, comprising: A first adjustment parameter is determined, and the water spraying amount is reduced according to the first adjustment parameter. A second adjustment parameter is determined, and the rotation speed of the fermentation tray is reduced according to the second adjustment parameter.
[0040] It should be understood that if the temperature in the fermentation box is < the preset threshold value, the heating device (such as heating wire) is started to increase the temperature; if the temperature is > the preset threshold value, the cooling device (such as air cooler) is started to decrease the temperature; temperature = threshold value → stop active intervention, keep the status quo; for stabilizing the temperature in the best interval of microbial activity, avoiding extreme temperature to damage the fermentation process.
[0041] The humidity of a certain fermentation tray < the threshold value → directional water spraying and humidifying is performed on the tray (precise control of the amount through the spray head + electromagnetic valve); the humidity of a certain fermentation tray > the threshold value → mechanical stirring is performed on the tray (through the electric telescopic column + stirring rod to turn the material); humidity = threshold value → no additional measures are taken; for quickly correcting the single-tray humidity deviation, preventing local drying or water accumulation from affecting the fermentation quality.
[0042] Neighbor disk humidity meets the standard (≤ threshold value): allow continuous water spraying to the target disk until its humidity meets the standard; neighbor disk humidity exceeds the standard (> threshold value): immediately start the stirring program for the neighbor disk and trigger the subsequent parameter adjustment judgment; avoid the chain over-standard of neighbor disk humidity caused by target disk humidification, and ensure the overall environment balance.
[0043] The first adjustment parameter (water spraying amount): proportionally reduce the unit time water spraying amount of the target disk (such as originally 5 seconds / time → reduced to 3 seconds / time); the second adjustment parameter (rotation speed): reduce the rotation speed of the stirring rod (such as originally 30 rpm → reduced to 20 rpm), and prolong the single stirring time to enhance the humidity dispersion effect; through reducing the newly added humidity load (water spraying amount ↓) and improving the humidity dispersion efficiency (rotation speed ↓), the double means break the stubborn high humidity problem.
