Description

Technical Field

[0001] The present invention belongs to the field of tea processing, and particularly relates to a monitoring device for the fermentation degree of tea. Background Art

[0002] Black tea is a strip-shaped dry tea product made from young tea leaves of tea trees through processes such as withering, rolling, fermentation, and drying. After brewing, it has the characteristics of red soup and red leaves. Among them, fermentation is a key process in the processing of black tea, which is usually carried out after rolling the tea strips tightly, commonly known as "sweating". Fermentation is a process in which tea leaves are spread out in a certain thickness on a fermentation tray and undergo an enzymatic reaction of biological oxidation in the air. The fermentation process reduces the tea polyphenols and tannic acid in the tea leaves, and generates new components such as theaflavins and thearubigins, as well as aromatic substances such as alcohols, aldehydes, ketones, and esters.

[0003] In the traditional black tea fermentation process, the fermentation degree is determined by manual experience. Since manual determination cannot achieve real-time and precise control, it is greatly affected by the technical level of workers, and can only be controlled within a certain range, unable to be precisely controlled, lacking scientificity and accuracy, easily resulting in too light or excessive fermentation of black tea, and it is difficult to guarantee the effect, which will lead to a reduction in the quality of tea leaves. Summary of the Invention

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. In the present invention, by making the sampling mechanism move above a plurality of fermentation winnowing trays in sequence and taking pictures, all the tea leaves can be monitored in real time. The sampling mechanism extracts the tea leaves in the fermentation winnowing tray and sends the samples into the glass, then adds hot water into the glass, and then detects the color of the tea water through a spectrometer, making the tea fermentation data more accurate to assist the staff in making judgments, thereby improving the quality of tea fermentation.

[0031] 2. In the present invention, by providing a plurality of sampling tubes and making the distances of the plurality of sampling tubes from the axis of the rotating disk increase in sequence, the tea leaves within the range of the fermentation winnowing tray can be stirred and sampled, so that the tea leaves with different fermentation degrees are mixed evenly, avoiding a large error in the detection data, and extracting the tea leaves at different positions.

[0032] 3. In the present invention, by providing a synchronization mechanism, when the driving mechanism drives the rotating disk to rotate, the rotating disk drives the switching disk to rotate synchronously through the positioning plug, so that the material taking channel and the sampling tubes are always communicated, avoiding the situation that after the rotating disk finishes rotating, the material taking channel and all the sampling tubes are not communicated, thereby avoiding the abnormal operation of the device.

[0033] 4. In the present invention, by providing a fixing mechanism, after the driving mechanism switches the connection object, it will fix the rotating disk to the installation shell through the fixing mechanism, thereby preventing the switching disk from driving the rotating disk to rotate, enabling the material taking channel to communicate with different sampling tubes, and thus being able to sample the tea leaves at different positions to ensure the accuracy of the data.

[0034] 5. In the present invention, by providing a slag removing mechanism and a drainage mechanism, after the glass is detected, the slag removing mechanism and the drainage mechanism can automatically remove the tea water and tea leaves in the glass so that it can be reused. There is no need for staff to assist in pouring the tea water in the glass, making the device more convenient to use and greatly reducing the labor intensity of the staff.

[0046] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0048] As Figures 1 - 10As shown in the figure, a monitoring device for the fermentation degree of tea leaves provided by the present invention includes a monitoring frame 1. A plurality of horizontally arranged placement rings 2 are installed on the monitoring frame 1. A fermentation winnowing basket 12 is placed on each placement ring 2. The fermentation winnowing basket 12 is used to place tea leaves so that the tea leaves ferment in the fermentation winnowing basket 12. A sliding frame 5 is slidably installed on the top of the monitoring frame 1. A switching component 8 is installed on the sliding frame 5. The switching component 8 includes a third servo motor 83 fixedly installed on the sliding frame 5. The output shaft of the third servo motor 83 is fixedly connected to a work position plate 81. A material guiding block 82 is also installed on the sliding frame 5. The material guiding block 82 is located below the work position plate 81. A plurality of uniformly distributed work position holes are provided on the work position plate 81. Each work position hole represents a work position, which are respectively a feeding work position, a brewing work position, and a detection work position in sequence. A glass cup 13 is inserted into each work position hole. The bottom of the glass cup 13 is in contact with the surface of the material guiding block 82. The glass cup 13 is made of a transparent material;

[0049] A concave area is provided on the material guiding block 82. The concave area corresponds to the detection work position. Transition inclined surfaces 821 are provided on both sides of the concave area. The distance between the bottom of the concave area and the bottom of the work position plate 81 is less than the height of the glass cup 13. When the third servo motor 83 drives the work position plate 81 to rotate, the work position plate 81 will drive all the glass cups 13 to rotate. When the glass cup 13 moves towards the concave area, the bottom of the glass cup 13 will move along the transition inclined surface 821 and fall into the interior of the concave area;

[0050] A spectrometer 10 is installed on the sliding frame 5. The spectrometer 10 is installed on one side of the sliding frame 5 at the detection work position. The spectrometer 10 is used to detect the sample in the glass cup 13 at the detection work position;

[0051] A brewing component 7 is also installed on the sliding frame 5. The brewing component 7 is installed on one side of the sliding frame 5 at the brewing work position. The output end of the brewing component 7 extends above the glass cup 13 at the brewing work position. The brewing component 7 is used to add hot water into the glass cup 13;

[0052] A sampling mechanism 3 is installed on the sliding frame 5. One end of the sampling mechanism 3 extends above the fermentation winnowing basket 12. The other end of the sampling mechanism 3 extends above the glass cup 13 at the feeding work position. The sampling mechanism 3 is used to extract the tea leaves in the fermentation winnowing basket 12 into the glass cup 13;

[0053] A camera 15 is also provided on the sampling mechanism 3. The camera 15 is used to take pictures of the tea leaves in the fermentation winnowing basket 12 for the staff to view the color of the tea leaves;

[0054] A power mechanism 6 is also installed on the monitoring frame 1. One end of the power mechanism 6 is in transmission connection with the sliding frame 5. The power mechanism 6 is used to drive the sliding frame 5 to move, so that the sliding frame 5 drives the sampling mechanism 3 to move above different fermentation winnowing trays 12, so as to detect the tea leaves in different fermentation winnowing trays 12.

[0055] The tea leaves to be fermented are placed in the fermentation winnowing tray 12 for fermentation. Then, the power mechanism 6 regularly drives the sliding frame 5 to move, so that the sampling mechanism 3 moves above a plurality of fermentation winnowing trays 12 in turn and takes pictures for the staff to monitor the tea leaves in real time. When the color of the tea leaves ferments to meet the requirements or is approximately in line with the requirements, the sampling mechanism 3 is started. The sampling mechanism 3 extracts the tea leaves in each fermentation winnowing tray 12 and sends the samples into the glass 13. The third servo motor 83 drives the working platform 81 to rotate one working position. The brewing assembly 7 adds hot water into the glass 13 to soak the tea leaves in the water. Then, the third servo motor 83 drives the working platform 81 to rotate one working position again, so that the glass 13 falls into the recessed area. Then, the color of the tea leaf water is detected by the spectrometer 10 to make the tea leaf fermentation data more accurate, so as to assist the staff in making judgments and improve the quality of tea leaf fermentation.

[0056] As Figures 2 - 3 shown, a monitoring device for the fermentation degree of tea leaves provided by the present invention. In this embodiment, the brewing assembly 7 includes a water storage tank 71 fixedly installed on the sliding frame 5. A water pump 72 is fixedly installed on the water storage tank 71. The water inlet of the water pump 72 extends into the interior of the water storage tank 71 through a water pipe. The water outlet of the water pump 72 is communicated with a water outlet pipe 73. One end of the water outlet pipe 73 extends above the glass 13. Water is contained in the interior of the water storage tank 71, and a heating device is arranged at the inner bottom of the water storage tank 71 to heat the water.

[0057] As Figures 1 - 7 shown, a monitoring device for the fermentation degree of tea leaves provided by the present invention. In this embodiment, the sampling mechanism 3 includes a lifting cylinder 32 that penetrates and is slidably installed on the sliding frame 5. One end of the lifting cylinder 32 is fixedly connected with an installation shell 37. A switching disk 312 and a rotating disk 313 are rotatably installed inside the installation shell 37. A connecting pipe 314 is fixedly installed on the switching disk 312. A material taking channel 315 communicated with the connecting pipe 314 is opened inside the switching disk 312. A plurality of sampling pipes 39 capable of being respectively communicated with the material taking channel 315 are fixedly connected to the bottom of the rotating disk 313. The plurality of sampling pipes 39 are evenly distributed around the axis of the rotating disk 313, and the distances of the plurality of sampling pipes 39 from the axis of the rotating disk 313 increase in sequence, so that the tea leaves within the range of the fermentation winnowing tray 12 can be stirred and sampled uniformly;

[0058] One end of the connecting pipe 314 is connected to a fixed inner pipe 311 through a rotary joint. The fixed inner pipe 311 passes through one end of the lifting cylinder 32 and is connected to a feeding hose 31. One end of the feeding hose 31 is connected to a discharge pipe 33. The discharge pipe 33 is fixedly installed on the sliding frame 5. One end of the discharge pipe 33 extends above a glass 13.

[0059] A suction pump 35 is fixedly installed on the sliding frame 5. The air inlet of the suction pump 35 is connected to a suction pipe 34. One end of the suction pipe 34 is connected to the discharge pipe 33. The port of the suction pipe 34 located inside the discharge pipe 33 is provided with a filter screen 94 to prevent tea leaves from falling into the suction pipe 34. In order to avoid air leakage from one end of the discharge pipe 33, an electromagnetic valve 310 is provided on the side of the discharge pipe 33 away from the lifting cylinder 32 and away from the suction pump 35.

[0060] A first telescopic rod 36 is also fixedly installed on the sliding frame 5. The movable end of the first telescopic rod 36 is fixedly connected to the lifting cylinder 32 through a connecting plate.

[0061] The sampling mechanism 3 further includes a driving mechanism 4. The driving mechanism 4 is installed on the mounting shell 37. The driving mechanism 4 is used to drive the rotating disk 313 or the switching disk 312 to rotate.

[0062] During sampling, the first telescopic rod 36 drives the lifting cylinder 32 to descend. The lifting cylinder 32 drives the sampling tube 39 to descend through the mounting shell 37, so that the sampling tube 39 is inserted into the tea leaves in the fermentation winnowing basket 12. Then the driving mechanism 4 drives the rotating disk 313 to rotate, thereby stirring the tea leaves, so that the tea leaves with different fermentation degrees are mixed evenly. Then the first telescopic rod 36 drives the sampling tube 39 to rise, so that the sampling tube 39 leaves the tea leaves. The driving mechanism 4 continues to drive the sampling tube 39 to rotate a certain angle, and then the first telescopic rod 36 drives the sampling tube 39 to approach the tea leaves again. The suction pump 35 is started, and the electromagnetic valve 310 is closed. The suction pump 35 sucks the tea leaves in the fermentation winnowing basket 12 through the sampling tube 39. When the tea leaves are sucked into the inside of the discharge pipe 33, the power supply of the suction pump 35 is cut off, and the electromagnetic valve 310 is opened. Under the action of gravity, the tea leaves in the discharge pipe 33 will slide into the glass 13. When it is judged that the tea leaves reach the inside of the discharge pipe 33, an infrared sensor can be used. The infrared sensor is arranged at the port position of the discharge pipe 33 above the suction pipe 34. When the infrared sensor detects that a foreign object passes through, the power supply of the suction pump 35 can be cut off, and the electromagnetic valve 310 can be opened.

[0063] Then the driving mechanism 4 drives the switching disk 312 to rotate, so that the material taking channel 315 is communicated with different sampling tubes 39 to extract tea leaves at different positions. This device can perform multiple groups of detection experiments to complete the comparison, so as to more accurately determine the fermentation degree and improve the tea quality.

[0064] When the driving mechanism 4 drives the rotating disk 313 to rotate, the rotating disk 313 can stir the tea leaves in the fermentation winnowing basket 12 through the sampling pipe 39, turning the tea leaves over. Before the fermentation is completed, it can replace the staff to turn the tea leaves regularly, reducing the workload of the staff. After the fermentation is completed, it can make the tea leaves with different fermentation degrees in the fermentation winnowing basket 12 mixed evenly, improving the sample quality and avoiding the situation of large errors in the detection data.

[0065] As Figures 1 - 5 As shown, a monitoring device for the fermentation degree of tea leaves provided by the present invention. In this embodiment, the driving mechanism 4 includes a lifting plate 43 slidably installed on the lifting cylinder 32. A second telescopic rod 44 is fixedly installed on the mounting shell 37, and the movable end of the second telescopic rod 44 is fixedly installed on the lifting plate 43. A first servo motor 41 is also fixedly installed on the lifting plate 43. The output shaft of the first servo motor 41 is fixedly connected with a driving gear 42. A first toothed ring 45 is fixedly connected to the switching disk 312, and a second toothed ring 46 is fixedly connected to the rotating disk 313. Both the first toothed ring 45 and the second toothed ring 46 can mesh with the driving gear 42.

[0066] The second telescopic rod 44 drives the lifting plate 43 and the first servo motor 41 to lift, so that the driving gear 42 can mesh with the first toothed ring 45, or the driving gear 42 can mesh with the second toothed ring 46, thereby driving the switching disk 312 or the rotating disk 313 to rotate.

[0067] As Figures 4 - 6 As shown, a monitoring device for the fermentation degree of tea leaves provided by the present invention. When the driving mechanism 4 drives the rotating disk 313 to rotate, since there is no connecting mechanism between the switching disk 312 and the rotating disk 313, the rotating disk 313 will not drive the switching disk 312 to rotate. After the rotating disk 313 finishes rotating, it may occur that the material taking channel 315 and all the sampling pipes 39 are not connected, making the device unable to operate normally, and it may be necessary for the staff to adjust manually. Therefore, in this embodiment, the sampling mechanism 3 further includes a synchronization mechanism 316. The synchronization mechanism 316 includes a mounting groove 3161 opened at the bottom of the switching disk 312. The mounting groove 3161 is located at an eccentric position of the switching disk 312. A positioning plug 3163 is slidably installed inside the mounting groove 3161. A first compression spring 3162 is connected between the positioning plug 3163 and the mounting groove 3161. One end of the positioning plug 3163 close to the rotating disk 313 is hemispherical. A positioning groove 3164 adapted to the positioning plug 3163 is opened on the side surface of the rotating disk 313. When one end of the positioning plug 3163 is inserted into the positioning groove 3164, the material taking channel 315 is communicated with one sampling pipe 39.

[0068] When the driving mechanism 4 drives the rotating disk 313 to rotate, the rotating disk 313 drives the switching disk 312 to rotate synchronously through the positioning plug post 3163, so that the material taking channel 315 and the sampling tube 39 are always communicated.

[0069] As Figures 3 - 5 and Figure 7 shown, a monitoring device for the fermentation degree of tea leaves provided by the present invention. When the driving mechanism 4 drives the switching disk 312 to rotate, the switching disk 312 will also drive the rotating disk 313 to rotate synchronously through the positioning plug post 3163, so that the material taking channel 315 cannot communicate with different sampling tubes 39, and thus it is impossible to sample different positions. Therefore, in this embodiment, the sampling mechanism 3 further includes a fixing mechanism 38. The fixing mechanism 38 includes a mounting frame 381 fixedly connected to the bottom of the mounting shell 37. A fixing plate 384 is fixedly connected to the mounting frame 381. A brake rod 385 is penetrated and slidably connected to the fixing plate 384. One end of the brake rod 385 close to the bottom of the rotating disk 313 is fixedly connected with a brake pad 383. A brake ring 382 adapted to the brake pad 383 is fixedly connected to the bottom of the rotating disk 313. A push frame 387 is slidably connected to the mounting frame 381. A second compression spring 386 is connected between the push frame 387 and the brake rod 385. One end of the push frame 387 is rotatably connected to the output shaft of the first servo motor 41.

[0070] When the second telescopic rod 44 drives the first servo motor 41 to rise, the first servo motor 41 drives the second compression spring 386 and the brake rod 385 to rise through the push frame 387. The brake rod 385 drives the brake pad 383 to abut against the brake ring 382. Under the large elastic action of the second compression spring 386, the rotating disk 313 is fixed to the mounting shell 37. Therefore, when the driving mechanism 4 drives the switching disk 312 to rotate, the positioning plug post 3163 will be disengaged from the positioning groove 3164. Only by making the first servo motor 41 drive the switching disk 312 to rotate a fixed angle can the material taking channel 315 communicate with the next sampling tube 39, so as to sample the tea leaves at different positions.

[0071] As Figures 1 - 2 shown, a monitoring device for the fermentation degree of tea leaves provided by the present invention. In this embodiment, the power mechanism 6 includes a second servo motor 61 fixedly installed on the monitoring frame 1. The output shaft of the second servo motor 61 is fixedly connected with a lead screw 62. The lead screw 62 is rotatably installed on the monitoring frame 1. The lead screw 62 is threadedly connected with the sliding frame 5.

[0072] The second servo motor 61 can drive the sliding frame 5 to move to a specified position through the lead screw 62, so that the sampling tube 39 can move above different fermentation winnowing trays 12, and then monitor the tea leaves in multiple fermentation winnowing trays 12.

[0073] As Figure 3 and Figures 8 - 10 shown, a monitoring device for the fermentation degree of tea leaves provided by the present invention. When using the monitoring device for the fermentation degree of tea leaves in the above-mentioned embodiment, it is necessary for the staff to manually clean the tea leaves and tea water in the glass 13, and then the tea leaves in other fermentation winnowing trays 12 can be detected, which is inconvenient to use. In this embodiment, the monitoring device for the fermentation degree of tea leaves further includes a slag removal mechanism 9 and a drainage mechanism 14. A cleaning station is also provided on the station plate 81. The slag removal mechanism 9 and the drainage mechanism 14 are both arranged on one side of the cleaning station;

[0074] The slag removal mechanism 9 is used to clean the tea leaves in the glass 13, and the drainage mechanism 14 is used to clean the tea water in the glass 13.

[0075] As Figure 3 and Figures 8 - 10 shown, a monitoring device for the fermentation degree of tea leaves provided by the present invention. In this embodiment, the slag removal mechanism 9 includes a plurality of filter meshes 94. Each filter mesh 94 is fixedly installed on the station plate 81 through a fixing rod 95. Each filter mesh 94 is located inside a glass 13. The upper surface of the filter mesh 94 is not lower than the upper surface of the station plate 81. The slag removal mechanism 9 further includes a fourth servo motor 91. The fourth servo motor 91 is fixedly installed on the sliding frame 5. The output shaft of the fourth servo motor 91 is fixedly connected with a cleaning rod 92. One end of the cleaning rod 92 is horizontally installed with a cleaning plate 93. The bottom of the cleaning plate 93 is in contact with the upper surface of the filter mesh 94. A collection box 96 is installed on the sliding frame 5. The collection box 96 is arranged on the side of the material guiding block 82, so that the fourth servo motor 91 can drive the cleaning plate 93 through the cleaning rod 92 to sweep the tea leaves on the filter mesh 94 into the collection box 96;

[0076] To avoid the glass 13 blocking the cleaning rod 92, the recessed area extends to one side of the cleaning station.

[0077] After the spectrometer 10 finishes detecting the tea water in the glass 13, the third servo motor 83 drives the glass 13 to rotate to the cleaning station through the station plate 81. At the same time, the fourth servo motor 91 drives the cleaning rod 92 to rotate, and the cleaning rod 92 sweeps the tea leaves on the filter mesh 94 into the collection box 96 through the cleaning plate 93.

[0078] As Figure 3 and Figures 8 - 10 shown, a monitoring device for the fermentation degree of tea leaves provided by the present invention. In this embodiment, the drainage mechanism 14 includes a plurality of water outlet valves and an unlocking assembly. Each water outlet valve is installed at the bottom of a glass 13;

[0079] The water outlet valve includes a water inlet pipe 142 fixedly installed at the inner bottom of the glass 13. A second water inlet hole 143 is formed on the side surface of the water inlet pipe 142. A plugging inner pipe 144 is slidably installed inside the water inlet pipe 142. One end of the plugging inner pipe 144 extending outside the glass 13 is fixedly installed with a permanent magnet 147. A tension spring 146 is connected between the permanent magnet 147 and the glass 13. A first water inlet hole 141 and a water outlet hole 145 are formed on the side surface of the plugging inner pipe 144 located inside the water inlet pipe 142. Initially, the first water inlet hole 141 and the water outlet hole 145 are respectively located on both sides of the second water inlet hole 143, and both the first water inlet hole 141 and the water outlet hole 145 are not communicated with the second water inlet hole 143. The distance from the axis of the first water inlet hole 141 to the axis of the second water inlet hole 143 is not less than the distance from the axis of the second water inlet hole 143 to the bottom of the water inlet pipe 142, so that when the first water inlet hole 141 and the second water inlet hole 143 are communicated, the water outlet hole 145 can extend outside the water inlet pipe 142, so that the tea in the glass 13 can pass through the second water inlet hole 143 and the first water inlet hole 141 and be discharged from the water outlet hole 145;

[0080] The unlocking assembly includes a drain groove 149 formed at the bottom of the recessed area. An electromagnet 148 is installed inside the drain groove 149. The electromagnet 148 is lower than the surface of the guide block 82. One end of the drain groove 149 is communicated with a drain pipe 1410.

[0081] After the glass 13 rotates to the cleaning station, the electromagnet 148 is started. The electromagnet 148 will adsorb the permanent magnet 147. The permanent magnet 147 will overcome the elastic force of the tension spring 146 and drive the plugging inner pipe 144 to descend, so that the first water inlet hole 141 and the second water inlet hole 143 are communicated. The tea in the glass 13 can enter the inside of the plugging inner pipe 144 from the second water inlet hole 143 and the first water inlet hole 141, and finally be discharged from the water outlet hole 145. The tea will flow into the drain groove 149 and finally be discharged from the drain pipe 1410;

[0082] After the glass 13 on the cleaning station rotates away, the permanent magnet 147 is no longer adsorbed by the electromagnet 148. Under the action of the tension spring 146, the plugging inner pipe 144 plugs the second water inlet hole 143 again, so that the glass 13 can continue to be used.

[0083] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
