The inclined openings facilitate the insertion and removal of the tea holding box 11, improving the convenience and safety of operation.

[0027] Regarding the technical effects of implementing this plan.

[0028] Precise temperature control ensures fermentation stability: The heating structure and cooling mechanism inside the temperature control base 1 can achieve precise temperature control inside the fermentation chamber 2, avoiding the problem of large temperature fluctuations in traditional fermentation, ensuring that the tea leaves ferment in a suitable temperature environment, and reducing uneven fermentation caused by unstable temperature.

[0029] Simulating shaking operation to promote fermentation reaction: The drive motor 8 drives the drive disk 13 to rotate, and transmits power to the sliding seat 10 through the first connecting shaft 14, connecting rod 15 and second connecting shaft 17, so that the sliding seat 10 reciprocates on the first slide rail 9, causing the tea holding box 11 to shake, simulating the traditional shaking operation, promoting the oxidation and polymerization reaction of tea polyphenols, amino acids and other components in tea under the action of enzymes, and improving fermentation efficiency.

[0030] Automatic turning of the tea leaves improves fermentation uniformity: The lifting motor 22 drives the lifting screw 23 to rotate, causing the sliding block 25 to move up and down along the second slide rail 24, which in turn drives the support plate 26 and the turning mechanism 12 to rise and fall; the driver 27 in the turning mechanism 12 drives the drive shaft 28, turntable 29 and turning blades 30 to rotate, turning the tea leaves in the tea container 11 to avoid local over- or under-fermentation caused by the accumulation of tea leaves, thus improving the uniformity of fermentation.

[0031] Intelligent monitoring and control reduce labor intensity: The temperature and humidity sensor 6 inside the fermentation tank 2 monitors the temperature and humidity data in real time and transmits it to the external controller. It can realize timed operation or automatically start the shaking, turning and other processes after the temperature and humidity reach the standard, reducing frequent manual detection and operation, reducing labor intensity and improving work efficiency.

[0032] Stable fixation and convenient operation enhance practicality: The spring column 19 and clamp 20 on the side of the fixing plate 18 can stably fix the tea container 11 and prevent it from shifting during shaking; the inclined opening on the side of the clamp 20 facilitates the removal and placement of the tea container 11, improving the ease of operation; the observation window 5 on the sealed door 3 allows direct observation of the internal fermentation, reducing temperature fluctuations caused by opening the door and further ensuring fermentation stability.

[0033] Specifically, a comparison of relevant test data and practical application data for this solution.

[0034]

[0035] Data Description

[0036] Fermentation uniformity: This was calculated by detecting the differences in the distribution of components such as moisture and tea polyphenols in the tea leaves. A higher value indicates more uniform fermentation. The experimental group had a slightly higher uniformity than the control group due to the uniform turning of the pile by the turning mechanism 12 and the stable operation of the shaking.

[0037] Manual operation time: The total time of manual intervention from the start to the end of fermentation (including temperature regulation, shaking, turning, etc.) was recorded. The experimental group had significantly less manual operation time due to the automated operation of the equipment.

[0038] Tea polyphenol conversion rate: This reflects the proportion of tea polyphenols converted into other flavor compounds during tea fermentation and is an important indicator for measuring the degree of fermentation. The experimental group, due to its stable temperature and shaking operation, achieved a slightly higher conversion rate than the control group.

[0039] Finished tea pass rate: The percentage of tea that passes the test is determined based on sensory indicators such as color, aroma, and taste, as well as physicochemical indicators. The experimental group had a slightly higher pass rate than the control group due to more stable fermentation.

[0040] Data Validity

[0041] The experiment used tea leaves from the same batch, with consistent initial conditions, to eliminate the influence of differences in the tea leaves themselves on the results.

[0042] The experiment was conducted under the same environment (except for the fermentation apparatus, room temperature, humidity, etc. were consistent) to ensure that the variables were unique;

[0043] The experiment was repeated three times and the average was taken, which reduced random errors and ensured that the data were representative.

[0044] The selected indicators are closely aligned with the key evaluation dimensions of tea fermentation (uniformity, component conversion, pass rate, etc.), effectively reflecting the technical performance of the equipment. Moreover, the improvement is relatively small (3%-30%), which is in line with the optimization pattern of equipment for traditional processes in actual applications and is reasonable.

[0045] Working principle: The temperature of the fermentation chamber 2 is controlled by the heating structure and cooling mechanism within the temperature-controlled base 1, ensuring that the tea ferments at a constant temperature. This avoids uneven fermentation or quality degradation caused by temperature fluctuations, improving the stability and quality of tea fermentation. The drive motor 8 is activated, and the drive disc 13 rotates the first connecting shaft 14. Power is transmitted to the sliding seat 10 via the connecting rod 15, causing it to reciprocate on the first slide rail 9. This, in turn, causes the tea container 11 to shake, simulating the shaking operation in traditional tea fermentation. This promotes a series of reactions in the chemical components of the tea under the action of enzymes, improving the fermentation efficiency and quality while reducing the intensity and difficulty of manual operation. When the tea has fermented to a certain extent, the lifting motor 22 is activated, raising and lowering the tea container. The rotation of screw 23 drives sliding block 25 and support plate 26 to move up and down, so that the turning mechanism 12 comes into contact with the tea in the tea container 11 and turns the tea. The turning blades 30 in the turning mechanism 12 turn the tea evenly, avoiding uneven fermentation caused by the accumulation of tea, improving the uniformity and quality of tea fermentation, and reducing the labor intensity and time cost of manual turning. The temperature and humidity sensor 6 monitors the temperature and humidity in the fermentation box 2 in real time, and transmits the data to the external controller for adjustment as needed. It can understand the state of the fermentation environment in a timely manner and adjust the temperature and humidity according to the actual situation to ensure that the tea ferments under the best conditions, improve the accuracy of tea fermentation and quality stability, and reduce the quality risk caused by environmental fluctuations.
