[0002] During the tea fermentation process, the prior art usually piles the tea leaves in a fermentation tank, monitors the temperature, humidity and oxygen concentration in the tank in real time, and promotes the fermentation of the tea leaves through timely ventilation, temperature control and humidification; In the steps before tea fermentation, the tea leaves are affected by factors such as picking methods, preliminary treatment, processing technology, physical and chemical changes during the fermentation process, as well as equipment and operation, which result in the fermented tea leaves containing broken tea leaves. Broken tea leaves tend to absorb water and oxygen faster than whole leaves, accelerating the oxidation and fermentation process.

Moreover, since there is less tea leaves in each fermentation cylinder, broken tea leaves will be discharged from the interception net during the frying process, and the discharged broken tea leaves will accumulate at the bottom of the fermentation tank. Filtering the broken tea leaves can avoid uneven fermentation and thus ensure the fermentation quality of the fermented tea leaves. Frying the tea leaves by rotating the fermentation cylinder facilitates fermentation and filtration, and can avoid the existing equipment that flips the tea leaves by rotating the rod, which leads to direct squeezing and damage of the tea leaves during the flipping process, and thus leads to the production of more broken tea leaves.

[0015] The gas is ejected through the air jet hole, and the ejected gas will push the tea leaves remaining in the circular connecting block and the connecting hose, and can prevent the tea leaves from being broken due to the residual tea leaves and the closing of the solenoid valve.

[0016] When the fermentation cylinder is driven to rotate and tumble by rotating the motor, the DD motor will also drive the circular connecting block and the fermentation cylinder to rotate, and can also make the tea leaves move back and forth between the two ends of the fermentation cylinder, thereby increasing the stir-frying effect of the tea leaves, making the fermentation degree of the tea leaves more uniform, and better discharging broken tea leaves, thereby achieving a better fermentation effect.

[0017] During the discharge process, when the pushing plate moves and pushes the tea leaves, the gas ejected pushes the tea leaves to move, which can speed up the discharge of the fermented tea leaves and avoid tea leaves residue. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] It also includes a baffle 321 , and each circular connecting block 6 is fixedly connected with a baffle 321 .

[0029] The specific working steps are: The external feeding device is connected to the feed pipe 5, and the external collecting device is connected to the lower part of the through-tube 2. The external collecting device is provided with two collecting bins, and different tea leaves can enter different collecting bins by changing the flow channel, one collecting bin is used to collect unfermented tea leaves, and the other collecting bin is used to collect fermented tea leaves; the two hoses on the connecting head 311 are respectively connected to the external water supply device and the air supply device, and the lower hose of the connecting head 311 is respectively connected to each air inlet pipe 112 and the water inlet pipe 102; the lower connecting pipe 13 is connected to the external air supply device, and the upper external air supply device is connected to the suction pump.

[0030] When the tea leaves are fermented, the pneumatic multi-stage push rod 3 is first controlled to drive the blocking block 4 to descend. When the upper side of the blocking portion 4001 of the blocking block 4 is flush with the bottom of the lowest circular connecting block 6 and the air bag 1 301 is aligned with the circular connecting block 6, it stops descending, and then the tea leaves are sent to the feeding pipe 5 through the external feeding equipment, and then the tea leaves enter the through-tube 2 through the feeding pipe 5. When the tea leaves enter the through-tube 2, they will be blocked by the blocking portion 4001 of the blocking block 4 and accumulated in the space between the blocking block 4 and the through-tube 2, and the tea leaves accumulated on the blocking block 4 will flow to the circular connecting block 6. At this time, the solenoid valve 10 is in an open state, so that the tea leaves can enter the fermentation cylinder 7 through the circular connecting block 6. During the feeding process, the tea leaves have poor fluidity and are not easy to enter the fermentation cylinder 7. An external air pump is used to supply air to the airbag 301 through the connecting hose 303 and the air supply pipe 302 in turn, so that the airbag 301 expands and pushes the tea leaves into the circular connecting block 6. After the tea leaves are pushed in, the external air pump inhales air to shrink the airbag 301 to restore it to its original state. When the airbag 301 shrinks, the tea leaves accumulated on the top of the airbag 301 will fall onto the blocking part 4001, and then the airbag 301 expands again to push the tea leaves into the circular connecting block 6 and the fermentation cylinder 7. Since the amount pushed in each time is similar, the pushing work can be performed multiple times until the tea leaves that are larger than half of the space of the fermentation cylinder 7 are pushed in, and then the pushing is stopped, and then the solenoid valve 10 is closed.

[0031] At this time, the tea leaves can no longer enter the fermentation cylinder 7, and then the blocking block 4 is controlled to rise to the position of the circular connecting block 6 of the upper layer, so that the tea leaves enter the fermentation cylinder 7 of the upper layer, and this process is repeated until all the fermentation cylinders 7 are filled with fermented tea leaves. When the tea leaves are pushed in, some of the tea leaves will remain on the circular connecting block 6. When the solenoid valve 10 is closed, it is easy to squeeze the tea leaves, causing the tea leaves to break. When the blocking block 4 rises to feed the fermentation cylinder 7 above, the rise of the blocking block 4 will drive the jet block 14 to rise together, and the jet hole 14001 will be aligned with the circular connecting block 6 below. When feeding the circular connecting block 6 above, At this time, part of the gas sent into the air supply pipe 302 will be discharged to the jet hole 14001 and ejected from the jet hole 14001. The ejected gas will push the tea leaves remaining in the circular connecting block 6 and the connecting hose 11, and can avoid the tea leaves remaining and the closure of the solenoid valve 10 causing the tea leaves to be broken. Since the fermentation cylinders 7 distributed upper and lower are staggered, when the blocking block 4 rises to feed the upper fermentation cylinder 7, the rotating motor 2 304 drives the air bag 1 301 to rotate and align with the upper fermentation cylinder 7 through the pneumatic multi-stage push rod 3 and the blocking block 4, and the jet hole 14001 will also be driven to align with the fermentation cylinder 7 below.

[0032] After all the fermentation cylinders 7 are loaded with tea leaves, the heating device of the fermentation tank 1 will heat the inside of the fermentation tank 1, thereby starting the fermentation work. During the fermentation process, the temperature sensor, the humidity sensor and the oxygen content sensor respectively detect the temperature, humidity and oxygen content in the fermentation tank 1. When the temperature in the fermentation cylinder 7 is low, the temperature of the heating device of the fermentation tank 1 increases, so that the temperature inside the fermentation tank 1 increases. When the humidity in the fermentation cylinder 7 is low, the external water supply equipment will supply water to the water inlet pipe through the hose on the connector 311. 102 is used to supply water, so that the water passes through the water inlet pipe 102, the connecting groove 7001 and the water collecting cavity 10101 in sequence, and then is sprayed out from the water spray hole 10102, and the sprayed water will contact the tea leaves, thereby humidifying the tea leaves. When the oxygen content in the fermentation cylinder 7 is low, the external air supply device will supply oxygen to the connecting pipe 13, so that the gas is sprayed into the fermentation tank 1 through the connecting pipe 13 in sequence, thereby increasing the oxygen content in the fermentation tank 1. When oxygen is supplied, the connecting pipe 13 at the upper part of the fermentation tank 1 will be pumped by the air pump to generate oxygen. The carbon dioxide produced by fermentation is extracted and discharged to the outside. During fermentation, the rotating motor 8 will drive the fermentation cylinder 7 to rotate 360 ​​degrees and then rotate back 360 degrees, and repeatedly drive the fermentation cylinder 7 to rotate. At this time, the tea leaves in the fermentation cylinder 7 will be driven to roll, thereby playing a stir-frying role. The tea leaves to be fermented are distributed in multiple different spaces through multiple fermentation cylinders 7, and the tea leaves are driven to roll in each separate space, so that the tea leaves can be better in contact with oxygen, water and heat in the fermentation tank 1, and then fermented better, and the fermentation speed is accelerated. Since there are fewer tea leaves in each fermentation cylinder 7, broken tea leaves will be discharged from the interception net 9 during the stir-frying process, and the discharged broken tea leaves will accumulate at the bottom of the fermentation tank 1. Filtering the broken tea leaves can avoid uneven fermentation, thereby ensuring the fermentation quality of the fermented tea leaves; and turning the fermentation cylinder 7 to stir the tea leaves is convenient for fermentation and filtration, which can avoid the existing equipment turning the tea leaves by the rotating rod, resulting in direct squeezing and damage of the tea leaves during the turning process, thereby resulting in more broken tea leaves.

[0033] When the broken tea leaves are discharged and fall, they are easy to fall into the fermentation cylinder 7 below, resulting in poor filtering effect of the broken tea leaves. Therefore, the baffle 321 will block the falling broken tea leaves when the broken tea leaves fall, preventing the broken tea leaves from entering the fermentation cylinder 7. After the tea fermentation work is completed, the lifting part 1001 is driven to rise by the electric push rod 312. At this time, the front of the fermentation tank 1 is opened, and then the broken tea leaves are taken out.

[0034] It should be noted that after the tea leaves are fed into the fermentation cylinder 7, excess tea leaves will accumulate on the blocking block 4. At this time, the blocking block 4 is controlled to descend to the lower part of the through-tube 2. Since the lower diameter of the through-tube 2 is larger than the middle diameter and the upper diameter of the through-tube 2, the blocking block 4 cannot contact the inner wall of the through-tube 2, and then the pneumatic multi-stage push rod 3 will drive the blocking block 4 to continue to move up and down, causing the blocking block 4 to shake. At this time, the tea leaves accumulated on the blocking block 4 will be shaken to flow to the outside of the blocking block 4, and fall from the through-tube 2 to the tea collection bin in the external collection device, and then the blocking block 4 is controlled to rise back to its original position. Subsequently, the tea leaves in the tea collection bin can be taken out and replenished to the external feeding device.

[0035] When discharging tea leaves, the DD motor 12 can be controlled to drive the circular connecting block 6 and the fermentation cylinder 7 to rotate, so that the fermentation cylinder 7 and the circular connecting block 6 rotate, and the fermentation cylinder 7 is tilted away from one end of the through-tube 2 toward the bottom of the fermentation tank 1. At this time, the connection between the circular connecting block 6 and the through-tube 2 is a connecting hose 11, so that the circular connecting block 6 drives the connecting hose 11 to rotate together, and the connecting hose 11 will also be in a tilted state, and then the tea leaves can flow from the blocking block 4 to the connecting hose 11, the circular connecting block 6 and the fermentation cylinder 7 in sequence. When the fermented tea leaves are discharged, the DD motor 12 can be used to drive the connecting hose 11, the circular connecting block 6 and the fermentation cylinder 7 to rotate, so that the fermentation cylinder 7 is away from one end of the through-tube 2 and tilted toward the top of the fermentation tank 1, and then the solenoid valve 10 is opened, so that the tea leaves are automatically discharged into the through-tube 2. , and then discharged from the through pipe 2 to the external collecting device. Before the tea leaves are discharged, the external collecting device will change the flow channel so that the fermented tea leaves are discharged into the collecting bin for collecting the fermented tea leaves. In this way, all the fermentation work of the tea leaves is completed. It should be noted that during the fermentation process, the circular connecting block 6, the fermentation cylinder 7 and the connecting hose 11 can be driven by the DD motor 12 to reciprocate at an angle of 60 degrees in the vertical direction. At this time, in addition to the tea leaves being tumbled by the rotating motor 8 to drive the fermentation cylinder 7 to rotate, the DD motor 12 will also drive the circular connecting block 6 and the fermentation cylinder 7 to rotate, and can also make the tea leaves move back and forth between the two ends of the fermentation cylinder 7, thereby increasing the stir-frying effect of the tea leaves, making the fermentation degree of the tea leaves more uniform, and better discharging the broken tea leaves, thereby achieving a better fermentation effect.

[0036] When the fermented tea leaves need to be discharged, the external air supply device supplies air to the airbag 2 111 through the connector 311 and the air inlet pipe 112, so that the airbag 2 111 expands and drives the push plate 113 to move, and the push plate 113 pushes the fermented tea leaves to move. Since the airbag 2 111 is connected to the connecting cavity 11302, while the airbag 2 111 expands, part of the gas will pass through the connecting cavity 11302 and be ejected from the annular jet groove 11301, so that the airbag 2 111 expands and drives the push plate 113 to move, and the high-pressure gas ejected from the annular jet groove 11301 will blow the fermented tea leaves, so that the fermented tea leaves are quickly discharged, and the fermented tea leaves can be avoided from remaining at the angle of the fermentation cylinder 7. When it is monitored that all the fermented tea leaves have been discharged, the gas supply can be stopped; thereby, in the process of discharging, when the push plate 113 moves and pushes the tea leaves, the ejected gas pushes the tea leaves to move, which can speed up the discharge of the fermented tea leaves and avoid tea leaves remaining.

[0037] Example 2 On the basis of Example 1, Figure 5-Figure 7 As shown, a brush plate 201 is also included; each circular connecting block 6 is fixedly connected to a brush plate 201; and the brush plate 201 is provided with a plurality of bristles.

[0038] A fermentation method for selenium-enriched tea based on microorganisms; the specific steps are as follows: Step 1: Select tea leaves without pesticide residues and rich in selenium as raw materials, select microbial strains suitable for fermentation, and activate and amplify them to ensure sufficient active bacterial flora; Step 2: Thoroughly clean and disinfect all tools and containers, set the fermentation room temperature to 25℃-30℃ and the relative humidity to 60%-80% to prevent contamination by bacteria; Step 3: Spray the activated microbial liquid evenly onto the treated tea leaves, ensuring that each part is exposed to a sufficient number of bacteria, and input the inoculated tea leaves into the fermentation cylinder 7 in the fermentation tank 1; Step 4: Control the fermentation cylinder 7 to rotate and turn the tea leaves in a timely manner to ensure uniform fermentation and promote gas exchange, monitor parameters such as temperature, oxygen content and water content, and adjust them when necessary to ensure smooth fermentation. The broken tea leaves can be filtered through the fermentation cylinder 7, and the fermentation cylinder 7 can be rotated to stir-fry, avoiding the existing equipment that turns the tea leaves by rotating the rod, resulting in direct squeezing and damage of the tea leaves during the turning process, thereby resulting in more broken tea leaves; Step 5: After fermentation is completed, the tea leaves are dried at low temperature or treated at high temperature for a short time to kill residual microorganisms and fix the fermentation products. The finished product is sealed and packaged using food-grade packaging materials, and the production date and shelf life are marked to ensure product quality and safety.

[0039] The specific working steps are: During fermentation, the tea leaves can be exposed to the heat and oxygen inside the fermentation tank 1 through the intercepting net 9, and the tea leaves can be prevented from falling from the fermentation cylinder 7. However, the tea leaves may be inserted into the mesh holes of the intercepting net 9, affecting the stirring of the tea leaves and the discharge of broken tea leaves, resulting in uneven fermentation degrees, and easily causing residues when the tea leaves are discharged. Therefore, the fermentation cylinder 7 will be driven by the rotating motor 8 during fermentation and discharge. At this time, the bristles on the brush plate 201 can brush off the tea leaves inserted in the mesh holes of the intercepting net 9, thereby preventing the tea leaves inserted in the mesh holes of the intercepting net 9 from being unevenly fermented and unable to be discharged in time.
