Description

Technical Field

[0001] The present invention relates to the technical field of tea processing, and specifically to an intelligent fermentation device and processing method for tea processing. Background Technique

[0002] Tea processing refers to the process of processing fresh tea buds and leaves into various semi-finished or finished teas through a series of processes. This process includes multiple key steps: withering, fixation, rolling, fermentation (for black tea, etc.), and drying. Each step has an important impact on the final quality of the tea. During the fermentation process, a fermentation device is needed to perform the fermentation operation on the tea.

[0003] However, when the existing intelligent fermentation device and processing method for tea processing are in use, the tea leaves are piled up together, which is not convenient for adjusting and controlling the temperature during fermentation. Too high or too low temperature will affect the quality of tea fermentation. Moreover, it is not convenient to filter and collect the liquid accumulated during the fermentation process. The accumulation of the liquid will cause the tea leaves to rot and also affect the quality of tea fermentation, thereby affecting the quality of tea processing.

[0015] A processing method for tea processing, using the intelligent fermentation device for tea processing as described above, includes the following steps:

[0016] S1: When it is necessary to ferment tea, open the box door, put the processed tea into the enclosure plate and spread it flat for fermentation. Under the action of gravity, it can drive the hollow cover and the enclosure plate to move downward. At the same time, it drives the connecting plate to move downward, and the second spring is compressed. And when the enclosure plate moves downward, it can drive the pushing block to move downward through the connecting rod and abut against the top of the sliding plate, so as to be able to push the sliding plate to move downward. At the same time, the third spring is compressed, so that the circular hole coincides with the first connecting pipe and the second connecting pipe;

[0017] Specifically, the fermentation process of tea in the fermentation device includes:

[0018] Pretreatment and vacuum nitrogen replacement stage: Spread the tea leaves with a moisture content of 60%-65% after withering evenly on the enclosure plate, and the laying thickness is 5-8 cm; Turn on the nitrogen injection device, inject nitrogen with a purity of ≥99.99% into the fermentation tank at a flow rate of 6-10 L / min until the oxygen concentration detector shows that the oxygen concentration in the fermentation tank is ≤0.5%; Maintain the nitrogen environment, stabilize the temperature at 30-40 °C through the circulating water system, and stand for fermentation for 2-4 hours. During this period, turn the tea leaves at a low speed of 10-15 revolutions per minute through the turning mechanism every 30 minutes to promote the uniform synthesis of γ-aminobutyric acid;

[0019] Secondary vacuum fermentation stage: After the tea leaves are processed by the cell wall breaking device, they are returned to the fermentation tank. The pressure of the fermentation tank is adjusted to -0.05~-0.08 MPa through an anaerobic vacuum generator, and nitrogen is injected to maintain the oxygen concentration ≤0.8%;

[0020] Start the gradient heating program of the temperature controller: heat up uniformly from 35°C to 45°C in the first hour, and maintain a constant temperature fermentation at 45 ± 1°C for the subsequent 2 - 5 hours. During this period, control the relative humidity in the fermentation chamber at 75% - 85% through the humidity sensor;

[0021] S2: During the fermentation process in S1, detect the temperature of the tea leaves through the temperature controller. When it is detected that the temperature of the tea leaves is relatively low, start the first water pump and open the first solenoid valve and the second solenoid valve. At this time, the hot water in the hot water tank can enter the hollow cover through the first U - shaped pipe, the water supply pipe, the first connecting pipe and the first hose, and then return to the hot water tank through the second hose, the second connecting pipe, the water return pipe and the second U - shaped pipe. Repeating this process can circulate and supply hot water into the hollow cover, thereby heating the tea leaves. After the heating is completed, turn off the first water pump. At this time, the hot water in the hollow cover can return to the hot water tank under the action of gravity through the water supply pipe and the water return pipe, and close the first solenoid valve and the second solenoid valve. When the temperature sensor detects that the temperature of the tea leaves is relatively high, start the second water pump and open the first solenoid valve and the third solenoid valve. At this time, similarly, cold water can be circulated and supplied into the hollow cover, thereby cooling the tea leaves, and then facilitating the intelligent adjustment and control of the temperature during tea leaf fermentation, ensuring the quality of tea leaf fermentation, and further ensuring the quality of tea processing;

[0022] S3: During the fermentation process, the accumulated liquid can fall into the liquid collection tank through the liquid leakage pipe, and then enter the collection box through the L - shaped pipe and the collection pipe for collection, thereby facilitating the filtration and collection of the accumulated liquid generated during fermentation, ensuring the quality of tea leaf fermentation, and further ensuring the quality of tea processing;

[0023] S4: When heating or cooling the tea leaves in the enclosure, when hot water or cold water enters the first connecting pipe, it will enter the fixed box and impact on the surface of the blades, causing the blades and the drive shaft to rotate. When the drive shaft rotates, it can drive the rotating disk to rotate through the rotating rod. When the rubber protrusion abuts against the end of the push rod, it can push the enclosure and the hollow cover to move away from the rotating disk. At the same time, drive the moving block to move through the connecting plate, and the first spring is compressed. When the rubber protrusion passes over the end of the push rod, the enclosure and the hollow cover can move back to their original positions under the action of the first spring. Repeating this process can make the enclosure and the hollow cover move back and forth, and at the same time, drive the tea leaves to move back and forth, forming a shaking effect;

[0024] S5: Moreover, when the tea leaves move away from the rotating disk along with the hollow cover and the surrounding plate, under the action of the first vertical surface, the upper-layer tea leaves can be blocked, while the lower-layer tea leaves can slide along the second inclined surface, so that the upper-layer tea leaves can fall on the top of the hollow cover, and the lower-layer tea leaves move to the upper part. When the tea leaves move back along with the hollow cover and the surrounding plate towards the rotating disk, under the action of the second vertical surface, the lower-layer tea leaves can be blocked, and at the same time, the upper-layer tea leaves can slide along the first inclined surface and fall on the top of the hollow cover. Repeating this process can intelligently reciprocate and turn the upper-layer and lower-layer tea leaves, which can not only improve the fermentation efficiency and quality, but also facilitate the discharge of the accumulated liquid.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] By setting a liquid supply mechanism and other components, when tea leaves need to be fermented, open the box door, put the processed tea leaves into the surrounding plate and spread them out for fermentation. Under the action of gravity, it can drive the hollow cover and the surrounding plate to move downward. At the same time, it drives the connecting plate to move downward, and the second spring is compressed. Moreover, when the surrounding plate moves downward, it can drive the pushing block to move downward through the connecting rod and abut against the top of the sliding plate, so as to be able to push the sliding plate downward. At the same time, the third spring is compressed, making the round hole coincide with the first connecting pipe and the second connecting pipe. During the fermentation process, the temperature of the tea leaves can be detected by the temperature sensor. When it is detected that the temperature of the tea leaves is relatively low, start the first water pump, open the first solenoid valve and the second solenoid valve. At this time, the hot water in the hot water tank can enter the hollow cover through the first U-shaped pipe, the water supply pipe, the first connecting pipe and the first hose, and then return to the hot water tank through the second hose, the second connecting pipe, the water return pipe and the second U-shaped pipe. Repeating this process can circulate and supply hot water into the hollow cover, so as to heat-treat the tea leaves. After the heating is completed, turn off the first water pump. At this time, the hot water in the hollow cover can return to the hot water tank through the water supply pipe and the water return pipe under the action of gravity, and close the first solenoid valve and the second solenoid valve. When the temperature sensor detects that the temperature of the tea leaves is relatively high, start the second water pump, open the first solenoid valve and the third solenoid valve. At this time, similarly, cold water can be circulated and supplied into the hollow cover, so as to cool the tea leaves, and thus facilitate the intelligent adjustment and control of the temperature during tea leaf fermentation, ensure the quality of tea leaf fermentation, and further ensure the quality of tea processing.

[0027] By setting a collection mechanism and other components, during the fermentation process, the accumulated liquid generated can fall into the liquid collection tank through the liquid leakage pipe, and then enter the collection box through the L-shaped pipe and the collection pipe for collection, so as to facilitate the filtration and collection of the accumulated liquid generated during fermentation, ensure the quality of tea leaf fermentation, and further ensure the quality of tea processing.

[0028] By providing a reciprocating movement mechanism and other components, when heating or cooling the tea leaves inside the enclosure, when hot water or cold water enters the first connecting pipe, it will enter the fixed box and impact on the surface of the blades, causing the blades and the drive shaft to rotate. When the drive shaft rotates, it can drive the rotating disk to rotate through the rotating rod. When the rubber protrusion abuts against the end of the push rod, it can push the enclosure and the hollow cover to move away from the rotating disk. At the same time, the connecting plate drives the moving block to move, and the first spring is compressed. When the rubber protrusion passes over the end of the push rod, the enclosure and the hollow cover can move back to their original positions under the action of the first spring. Repeating this process can make the enclosure and the hollow cover move reciprocally, and at the same time, drive the tea leaves to move reciprocally, forming a shaking effect. Moreover, when the tea leaves move away from the rotating disk along with the hollow cover and the enclosure, under the action of the first vertical surface, the upper-layer tea leaves can be blocked, while the lower-layer tea leaves can slide along the second inclined surface, so that the upper-layer tea leaves can fall on the top of the hollow cover, and the lower-layer tea leaves move to the upper layer. When the tea leaves move back to their original positions along with the hollow cover and the enclosure towards the rotating disk, under the action of the second vertical surface, the lower-layer tea leaves can be blocked, and at the same time, the upper-layer tea leaves can slide along the first inclined surface and fall on the top of the hollow cover. Repeating this process can intelligently reciprocally turn the upper-layer and lower-layer tea leaves, which can not only improve the fermentation efficiency and quality but also facilitate the discharge of the accumulated liquid.

When it is detected that the temperature of the tea leaves is relatively low, the first water pump 203 is started, and the first solenoid valve 206 and the second solenoid valve 209 are opened.

When it is necessary to ferment the tea leaves, open the box door 101, put the processed tea leaves into the enclosure 11 and spread them out for fermentation. Drive the sliding plate 402 to move downward through the moving component. At the same time, the third spring 703 is compressed, so that the circular hole 403 coincides with the first connecting pipe 208 and the second connecting pipe 212.

And when the enclosure 11 moves downward, it can drive the pushing block 702 to move downward through the connecting rod 701 and abut against the top of the sliding plate 402, so as to be able to push the sliding plate 402 to move downward.

[0047] The collection mechanism includes an L-shaped pipe 301 fixedly connected to the bottom of each liquid collecting tank 12, and the other end of the L-shaped pipe 301 is fixedly connected to a collecting pipe 302. A collecting box 303 is fixedly connected to the bottom of the fermentation box 1, and the lower end of the collecting pipe 302 is fixedly inserted into the collecting box 303. During the fermentation process, the generated liquid can fall into the liquid collecting tank 12 through the liquid leakage pipe 13, and then enter the collecting box 303 through the L-shaped pipe 301 and the collecting pipe 302 for collection, so as to facilitate the filtration and collection of the liquid generated during fermentation, ensure the quality of tea leaf fermentation, and further ensure the quality of tea processing.

[0048] A processing method for tea processing, using the intelligent fermentation device for tea processing as above, includes the following steps:

[0049] S1: When tea leaves need to be fermented, open the box door 101, put the processed tea leaves into the enclosure 11 and spread them out flat for fermentation. Under the action of gravity, it can drive the hollow cover 10 and the enclosure 11 to move downward. At the same time, it drives the connecting plate 608 to move downward, and the second spring 607 is compressed. Moreover, when the enclosure 11 moves downward, it can drive the pushing block 702 to move downward through the connecting rod 701 and abut against the top of the sliding plate 402, so as to be able to push the sliding plate 402 to move downward. At the same time, the third spring 703 is compressed, so that the circular hole 403 coincides with the first connecting pipe 208 and the second connecting pipe 212.

[0050] Specifically, the fermentation process of tea leaves in the fermentation device includes:

[0051] Pretreatment and vacuum nitrogen replacement stage: Evenly spread the tea leaves with a moisture content of 60%-65% after withering on the enclosure 11, and the laying thickness is 5-8 cm; Start the nitrogen injection device, inject nitrogen with a purity ≥99.99% into the fermentation box 1 at a flow rate of 6-10 L / min until the oxygen concentration detector shows that the oxygen concentration in the fermentation box 1 ≤0.5%; Maintain the nitrogen environment, stabilize the temperature at 30-40°C through the circulating water system, and let it stand and ferment for 2-4 hours. During this period, turn the tea leaves at a low speed of 10-15 revolutions per minute through the turning mechanism every 30 minutes to promote the uniform synthesis of γ-aminobutyric acid.

[0052] Secondary vacuum fermentation stage: After the tea leaves are processed by the cell wall breaking device, they are returned to the fermentation box 1. The pressure of the fermentation box 1 is adjusted to -0.05~-0.08 MPa by the anaerobic vacuum generator, and nitrogen is injected to maintain the oxygen concentration ≤0.8%.

[0053] Start the gradient temperature increase program of the temperature controller: Gradually increase the temperature from 35°C to 45°C at a constant speed in the first hour, and keep the temperature at 45±1°C for constant fermentation in the subsequent 2-5 hours. During this period, control the relative humidity in the fermentation box 1 to be 75%-85% through the humidity sensor.

[0054] S2: During the fermentation process in S1, the temperature of the tea leaves is detected by a temperature controller. When it is detected that the temperature of the tea leaves is relatively low, the first water pump 203 is started, and the first solenoid valve 206 and the second solenoid valve 209 are opened. At this time, the hot water in the hot water tank 201 can enter the hollow cover 10 through the first U-shaped pipe 205, the water supply pipe 207, the first connecting pipe 208, and the first hose 213. Then, it returns to the hot water tank 201 through the second hose 214, the second connecting pipe 212, the water return pipe 211, and the second U-shaped pipe 210. By repeating this process, hot water can be circulated into the hollow cover 10 to heat the tea leaves. After the heating is completed, the first water pump 203 is turned off. At this time, the hot water in the hollow cover 10 can return to the hot water tank 201 under the action of gravity through the water supply pipe 207 and the water return pipe 211, and the first solenoid valve 206 and the second solenoid valve 209 are closed. When the temperature sensor detects that the temperature of the tea leaves is relatively high, the second water pump 204 is started, and the first solenoid valve 206 and the third solenoid valve 215 are opened. At this time, similarly, cold water can be circulated into the hollow cover 10 to cool the tea leaves, thereby facilitating the intelligent adjustment and control of the temperature during tea leaf fermentation, ensuring the quality of tea leaf fermentation, and further ensuring the quality of tea processing;

[0055] S3: During the fermentation process, the accumulated liquid can fall onto the liquid collection tank 12 through the liquid leakage pipe 13, and then enter the collection box 303 through the L-shaped pipe 301 and the collection pipe 302 for collection, which is convenient for filtering and collecting the accumulated liquid generated during fermentation, ensuring the quality of tea leaf fermentation, and further ensuring the quality of tea processing;

[0056] S4: When heating or cooling the tea leaves in the enclosure 11, when hot water or cold water enters the first connecting pipe 208, it will enter the fixed box 801 and impact the surface of the blade 902, causing the blade 902 and the drive shaft 901 to rotate. When the drive shaft 901 rotates, it can drive the rotating disk 803 to rotate through the rotating rod 802. When the rubber protrusion 804 abuts against the end of the push rod 805, it can push the enclosure 11 and the hollow cover 10 to move away from the rotating disk 803. At the same time, the moving block 603 is driven to move through the connecting plate 608, and the first spring 604 is compressed. When the rubber protrusion 804 passes over the end of the push rod 805, the enclosure 11 and the hollow cover 10 can move back to their original positions under the action of the first spring 604. By repeating this process, the enclosure 11 and the hollow cover 10 can move reciprocally, and at the same time, drive the tea leaves to move reciprocally, forming a shaking effect;

[0057] S5: Moreover, when the tea leaves move away from the rotating disk 803 along with the hollow cover 10 and the surrounding plate 11, under the action of the first vertical surface 504, the upper-layer tea leaves can be blocked, while the lower-layer tea leaves can slide along the second inclined surface 507, so that the upper-layer tea leaves can fall on the top of the hollow cover 10, and the lower-layer tea leaves move to the upper part. When the tea leaves move back along with the hollow cover 10 and the surrounding plate 11 towards the rotating disk 803, under the action of the second vertical surface 506, the lower-layer tea leaves can be blocked. At the same time, the upper-layer tea leaves can slide along the first inclined surface 505 and fall on the top of the hollow cover 10. Repeating this process can intelligently reciprocally turn the upper-layer and lower-layer tea leaves, which can not only improve the fermentation efficiency and quality but also facilitate the discharge of the accumulated liquid.
