Description

Technical Field

[0001] This invention relates to the field of tea testing technology, specifically to a device for detecting the fermentation status of Pu-erh ripe tea based on microbial fermentation. Background Technology

[0002] The detection of fermentation status of Pu-erh ripe tea based on microbial fermentation is a complex and delicate process, involving the dynamics of microbial communities, changes in physicochemical indicators, and sensory quality assessment. Generally, the picked Pu-erh tea leaves are piled up and fermented by dominant strains such as Aspergillus niger, yeast, and lactic acid bacteria.

[0003] In the early stages of fermentation, Aspergillus niger decomposes macromolecular components such as cellulose and pectin in Pu-erh tea, promoting the oxidation of tea polyphenols and creating the unique mellow taste of ripe Pu-erh tea. In the middle and late stages of fermentation, yeast participates in the metabolism of sugars in Pu-erh tea, producing flavor substances such as ethanol and esters, enhancing the sweetness and aftertaste of the tea soup. The small amount of lactic acid bacteria present regulates the pH value of ripe Pu-erh tea, inhibits the growth of harmful bacteria, and participates in the synthesis of acidic substances, improving the refreshing taste of the tea soup.

[0004] By testing the pH value of ripe Pu-erh tea, the degree and state of fermentation can be scientifically and effectively determined quickly. In the early stage of Pu-erh tea fermentation, due to the weak microbial activity, the content of organic acids in the tea soup is relatively low, and the pH value is usually high, close to the weakly acidic range, generally between 6.68 and 6.70. In the middle stage of fermentation, microbial activity increases, producing a large amount of organic acids, causing the pH value of the tea soup to drop rapidly to 2.9-3.0. In the later stage of fermentation, the rate of organic acid production gradually slows down, and some organic acids may be further metabolized or transformed, causing the pH value of the tea soup to gradually rise back to between 3.5 and 3.7.

[0005] Currently, existing technologies require taking a suitable amount of tea leaves, brewing them with hot water to make tea soup, and then measuring the pH value of the tea soup using pH test paper or a pH meter. The pH value is then used to determine the fermentation state of Pu-erh ripe tea. However, the tea leaves piled for fermentation are quite thick, and existing technologies usually use manual methods to select tea leaves from the surface of the tea pile as samples. This is not convenient for detecting the pH value of tea leaves at different depths in the tea pile, which can easily affect the uniformity and accuracy of Pu-erh ripe tea fermentation state detection. Therefore, this technology does not meet the current needs. To address this, we propose a Pu-erh ripe tea fermentation state detection device based on microbial fermentation. Summary of the Invention

[0006] This invention provides a device for detecting the fermentation state of Pu-erh ripe tea based on microbial fermentation. This device can detect the pH value of tea leaves at different depths in a tea pile, thereby improving the uniformity and accuracy of Pu-erh ripe tea fermentation state detection.

Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0040] According to some embodiments of this disclosure, a device for detecting the fermentation state of Pu-erh ripe tea based on microbial fermentation is provided, with reference to... Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, the microbial fermentation-based Pu'er ripe tea fermentation state detection device includes a main body 100 and a robotic arm 110 located on the side of the main body 100. A connecting shell 120 is fixedly installed at the end of the robotic arm 110. A sampling tube 130 is movably arranged on the side of the connecting shell 120. A driving component 140 is arranged between the sampling tube 130 and the connecting shell 120. The driving component 140 is used to drive the sampling tube 130 to move up and down. A sealing shell 150 is rotatably arranged at the bottom of the sampling tube 130. The bottom of the sampling tube 130 can be opened and closed by opening and closing the sealing shell 150. A sampling clamp 160 for picking up tea leaves is movably arranged inside the sampling tube 130. A tea infusion container 200 is arranged on the side of the main body 100. The tea infusion container 200 is used to soak tea. A water inlet pipe 210 for injecting water into the tea infusion container 200 is also arranged inside the main body 100.

[0041] Thus, two sampling tubes 130 are inserted into the tea pile at different depths. The sampling clamp 160 picks up tea leaves at different depths and places them into the two sampling tubes 130. Then, the robotic arm 110 moves the two sampling tubes 130 and inserts them into the two tea infusion containers 200 respectively. Furthermore, during the movement of the sampling tubes 130, the tea leaves are broken up. Then, an appropriate amount of hot water is injected into the two tea infusion containers 200 through the water inlet pipe 210 to soak the tea. The sampling clamp 160 can also stir the tea infusion. By measuring and comparing the pH values ​​of the two tea infusions, the fermentation state of the tea leaves at different depths in the tea pile can be determined, thereby improving the uniformity and accuracy of the detection of the fermentation state of Pu'er ripe tea.

[0042] In some embodiments, where a driving assembly 140 is provided between the sampling tube 130 and the connecting housing 120, refer to Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the drive assembly 140 includes a first lead screw 141 and a second lead screw 142 inserted into the side of the connecting housing 120; a first threaded sleeve 143 threaded to the outside of the first lead screw 141; a second threaded sleeve 144 threaded to the outside of the second lead screw 142; bearings 145 fixedly sleeved on the upper ends of the first threaded sleeve 143 and the second threaded sleeve 144 respectively; and a first gear 146 fixedly sleeved in the middle of the first threaded sleeve 143 and the second threaded sleeve 144 respectively. The pitch of the first lead screw 141 is greater than the pitch of the second lead screw 142. The number of bearings 145 is set to two. The inner ring of one bearing 145 is fixedly sleeved on the upper end of the first threaded sleeve 143, and the inner ring of the other bearing 145 is fixedly sleeved on the upper end of the second threaded sleeve 144. Both bearings 145 are installed inside the connecting shell 120, and the outer rings of both bearings 145 are fixedly connected to the inner wall of the connecting shell 120. The number of first gears 146 is set to two. One first gear 146 is fixedly sleeved in the middle of the first threaded sleeve 143, and the other first gear 146 is fixedly sleeved in the middle of the second threaded sleeve 144.

[0043] The drive assembly 140 also includes a first motor 147 fixedly installed on the lower side of the connecting housing 120, a second gear 148 fixedly installed on the output end of the first motor 147 and meshing with the first gear 146, and a limiting rod 149 slidably inserted into the connecting housing 120 and the side of the sampling tube 130. The number of sampling tubes 130 is set to two, and the top of the two sampling tubes 130 is fixedly connected to the lower ends of the first lead screw 141 and the second lead screw 142, respectively. The second gear 148 is located between the two first gears 146, and the two first gears 146 mesh with the two sides of the second gear 148, respectively. The number of limiting rods 149 is set to two, and the lower ends of the two limiting rods 149 are slidably inserted into the side walls of the two sampling tubes 130, respectively. The middle ends of the two limiting rods 149 slidably penetrate the connecting housing 120, respectively.

[0044] In addition, two sealing shells 150 are provided, and the two sealing shells 150 together form a hemispherical shell to seal the lower end of the sampling tube 130. A first rotating shaft 151 is installed on the outside of each sealing shell 150. Both ends of the first rotating shaft 151 are rotatably inserted into the side wall of the sampling tube 130. A first torsion spring 152 is sleeved on the outside of each first rotating shaft 151. One end of the first torsion spring 152 is fixedly connected to the sealing shell 150, and the other end of the first torsion spring 152 is fixedly connected to the side wall of the sampling tube 130.

[0045] A first telescopic component 170 is fixedly installed on the inner wall of the sampling tube 130. A second motor 171 is fixedly installed on the telescopic end of the first telescopic component 170. The output shaft of the second motor 171 is fixedly connected to an inner tube 172. The inner tube 172 is located inside the sampling tube 130. A baffle 173 is rotatably installed at the lower end of the inner tube 172. There are two baffles 173, which together form a circular plate. A second rotating shaft 174 is installed on the outer side of each baffle 173. Both ends of the second rotating shaft 174 are rotatably inserted into the inner wall of the inner tube 172. A second torsion spring 175 is sleeved on the outer side of each second rotating shaft 174. One end of the second torsion spring 175 is fixedly connected to the baffle 173, and the other end of the second torsion spring 175 is fixedly connected to the side wall of the inner tube 172.

[0046] Furthermore, the sampling clip 160 is located inside the inner tube 172. The sampling clip 160 includes a mounting block 161, two sliders 162 slidably disposed inside the mounting block 161, a spring 163 connected between the two sliders 162, and clamping pieces 164 respectively fixedly connected to the lower side of the sliders 162. The sliders 162 are trapezoidal to prevent them from detaching from the mounting block. A second telescopic member 180 is fixedly installed on the inner wall of the inner tube 172. The telescopic end of the second telescopic member 180 is fixedly connected to the mounting block 161. Both the first telescopic member 170 and the second telescopic member 180 are electric lifting rods. A stop rod 181 is fixedly installed on the outer side of the clamping piece 164. A protrusion 182 is fixedly installed inside the inner tube 172. The number of protrusions 182 is set to two, and the two protrusions 182 are used in conjunction with the two stop rods 181 respectively.

[0047] Specifically, a first blade 190 and a second blade 191 are fixedly installed at the bottom of the inner tube 172. The number of the first blade 190 and the second blade 191 is set to two. The two first blades 190 are set vertically, and the two second blades 191 are set in a "V" shape at an angle. The length of the second blade 191 is greater than the length of the first blade 190, and the second blade 191 is set as a flexible soft blade, so that when the clamp 164 extends outward, the second blade 191 can be squeezed, thereby avoiding the second blade 191 from obstructing the movement of the clamp 164. The first blade 190 and the second blade 191 are both located inside the sampling tube 130.

[0048] Through the above technical solution, the microbial fermentation-based Pu'er ripe tea fermentation state detection device provided in this disclosure, when in use, uses the robotic arm 110 to move the connecting shell 120, causing the connecting shell 120 to move the sampling tube 130 to the upper side of the Pu'er ripe tea pile. Subsequently, the first motor 147 drives the second gear 148 to rotate. Through the meshing of the second gear 148 with the two first gears 146, the two first gears 146 respectively drive the first threaded sleeve 143 and the second threaded sleeve 144 to rotate. Through the cooperation of the first threaded sleeve 143 and the first screw 141, the first screw 141... One sampling tube 130 is inserted into the tea pile. At the same time, through the cooperation of the second threaded sleeve 144 and the second threaded screw 142, the second threaded screw 142 drives the other sampling tube 130 to be inserted into the tea pile as well. Since the pitch of the first threaded screw 141 is greater than the pitch of the second threaded screw 142, the first threaded screw 141 descends faster when the first threaded sleeve 143 and the second threaded sleeve 144 rotate the same number of turns. This causes the first threaded screw 141 to drive one sampling tube 130 to be inserted deep into the tea pile, while the second threaded screw 142 drives the other sampling tube 130 to be inserted shallowly into the tea pile.

[0049] Subsequently, the second telescopic member 180 drives the sampling clamp 160 to move downward. During this process, the downward-moving clamp 164 first abuts against the baffle 173, pushing the two baffles 173 to the sides. At the same time, the second torsion spring 175 is compressed and stores energy. Then, the clamp 164 continues to move downward, squeezing and deforming the second blade 191. Finally, the clamp 164 pushes open the two sealing shells 150. At the same time, the first torsion spring 152 is compressed and stores energy, causing the two clamps 164 to extend from the bottom of the sampling tube 130 and insert into the tea leaves. When the clamp 164 continues to drive the contact rod 181 to move downward, through the sliding cooperation between the contact rod 181 and the protrusion 182, the two contact rods 181 squeeze the two clamps 164 closer together, thereby making the two clamps 164 clamp the tea leaves tightly.

[0050] Then, the first telescopic member 170 moves the inner tube 172 and the sampling clamp 160 upwards together, causing the sampling clamp 160 to retract into the sampling tube 130 while holding the tea leaves. When the clamp 164 releases its contact with the sealing shell 150, the first torsion spring 152's rebound force causes the sealing shell 150 to reset and seal the sampling tube 130. Then, the second telescopic member 180 moves the sampling clamp 160 upwards and retracts into the inner tube 172. At this point, the two clamps 164 move away from each other and reset, allowing the held tea leaves to fall into the sampling tube 130. Furthermore, the clamps 164 no longer contact the second blade 191, allowing the second blade 191 to... The first telescopic component 170 drives the inner tube 172 to move down and reset. Then, the second motor 171 drives the inner tube 172, the first blade 190, and the second blade 191 to rotate, so that the first blade 190 and the second blade 191 cut the tea leaves in the sampling tube 130 into tea fragments. The substances in the broken tea leaves are more easily dissolved in hot water, which is conducive to quickly making tea soup. It can also control the output shaft of the second motor 171 to reciprocate, which can not only cut the tea leaves, but also avoid the problem of the wires connected to the second telescopic component 180 and the second motor 171 getting tangled after rotating in one direction for several turns.

[0051] Finally, while the two sampling tubes 130 shred the tea leaves at different depths in the tea pile, the sampling tubes 130 are reset, and the two sampling tubes 130 are inserted into the two tea infusion containers 200 by the robotic arm 110. Then, the sealing shell 150 is opened by the sampling clamp 160, so that the tea leaves in the sampling tubes 130 fall into the tea infusion containers 200. The appropriate amount of hot water is injected into the two tea infusion containers 200 through the water inlet pipe 210 to soak the tea leaves into tea soup. The pH values ​​of the two tea soups are then measured and compared using pH test paper or a pH meter to determine the fermentation state of the tea leaves at different depths in the tea pile, thereby improving the uniformity and accuracy of the detection of the fermentation state of Pu'er ripe tea.

[0052] It should be noted that the robotic arm 110 can perform activities such as extension, lifting, and rotation, thereby driving the connecting shell 120 and the sampling tube 130 to move. The robotic arm 110 is a technical means well known to those skilled in the art, and will not be described in detail here.

[0053] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 13As shown, the number of tea containers 200 is the same as the number of sampling tubes 130. The side of the machine body 100 is provided with a placement slot 201, the number of which is the same as the number of tea containers 200. The tea containers 200 are placed in the placement slots 201, the depth of which is greater than the height of the tea containers 200. A handle 202 is fixedly connected to the upper end of the tea container 200. The handle 202 is located outside the placement slot 201, making it easy to hold the handle 202 to pick up the tea container 200. A weighing instrument 203 is provided inside the machine body 100. The two weighing instruments 203 are respectively located at the bottom of the two placement slots 201. The weighing instruments 203 are used in conjunction with the tea containers 200, and the weighing instruments 203 are set as electronic weighing devices to facilitate the weighing of tea leaves in the tea containers 200.

[0054] The water inlet pipe 210 is Y-shaped, with one end connected to hot water. Both ends of the water inlet pipe 210 are connected to flexible hoses 211, and each end of the flexible hose 211 is connected to a valve 212. The valves 212 are electronically controlled valves. The outlets of the two valves 212 are respectively located above the two tea containers 200. Two third motors 213 are also fixedly installed inside the body 100. The output ends of the two third motors 213 are respectively fixedly connected to the upper side of the two valves 212. The second motor 171 and the third motor 213 are both micro motors.

[0055] Valve 212 has different states at different times.

[0056] For example, in some embodiments, reference Figure 1 and Figure 3 As shown, valve 212 can have a first state, which is when it is not in use. In the first state, the water outlet of valve 212 is located on the side above the tea container 200, so as to avoid obstructing the insertion of the lower end of sampling tube 130 into the tea container 200.

[0057] For example, in some embodiments, reference Figure 1 and Figure 4 As shown, valve 212 can have a second state, which is when in use. In the second state, the water outlet of valve 212 is located in the middle of the upper part of tea container 200, which facilitates the injection of hot water into tea container 200.

[0058] The valve 212 will now be described in detail with reference to the specific embodiments described above. (See also...) Figure 1 , Figure 3 , Figure 4 and Figure 13As shown, the lower ends of the two sampling tubes 130 are inserted into the two tea infusion containers 200 respectively. The sampling clamp 160 moves down, pushing open the baffle 173 and the sealing shell 150, so that the tea leaves in the sampling tubes 130 fall into the tea infusion containers 200. Then the sampling tubes 130 move up and out of the tea infusion containers 200. Subsequently, the third motor 213 drives the valve 212 to rotate, causing the hose 211 to bend and the water outlet of the valve 212 to move to the middle of the upper part of the tea infusion container 200. Then the two weighing instruments 203 weigh the tea leaves in the two tea infusion containers 200 respectively, so that the two valves 212 open and inject an appropriate amount of hot water into the two tea infusion containers 200 according to a certain ratio based on the weight of the two portions of tea leaves.

[0059] Finally, after valve 212 is closed, it is rotated again to the side of the tea infusion container 200. At this time, sampling tube 130 is lowered again and inserted into the tea infusion container 200, sealing the upper part of the tea infusion container 200 to a certain extent, so as to slow down the heat dissipation of the hot water in the tea infusion container 200 as much as possible. At the same time, sampling clamp 160 is lowered again, so that clamp plate 164 is inserted into the hot water. Clamp plate 164 rotates to stir the tea leaves and hot water, which can not only accelerate the steeping of the tea infusion, but also stir the tea infusion, making the tea infusion more uniform in texture, thereby improving the efficiency and accuracy of the pH value detection of the tea infusion.
