Description

Technical Field

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

[0002] Black tea is a dry tea product made from young leaves of tea trees through withering, rolling, fermentation, drying and other processes. It has the characteristics of red soup and red leaves after brewing. Fermentation is a key process in the processing of black tea. It is usually carried out after rolling and rolling the tea leaves, commonly known as "sweating". Fermentation is the process of spreading tea leaves in a certain thickness in a fermentation tray in the air, and the tea leaves undergo enzymatic reactions of biological oxidation. Fermentation reduces tea polyphenols and tannic acid in tea leaves, and produces new ingredients such as theaflavins and thearubigins, as well as aromatic substances such as alcohols, aldehydes, ketones, and esters.

Transition slopes 821 are provided on both sides of the recessed area. The distance between the bottom of the recessed area and the bottom of the station tray 81 is less than the height of the glass 13. When the third servo motor 83 drives the station tray 81 to rotate, the station tray 81 drives all the glasses 13 to rotate. When the glass 13 moves toward the recessed area, the bottom of the glass 13 moves along the transition slope 821 and falls into the interior of the recessed area. The slide frame 5 is provided with a spectrometer 10, which is installed on one side of the slide frame 5 located at the detection station. The spectrometer 10 is used to detect the sample in the glass 13 at the detection station.

The output end of the brewing assembly 7 extends above the glass 13 at the brewing station. The brewing assembly 7 is used to add hot water to the inside of the glass 13. The sliding frame 5 is provided with a sampling mechanism 3, one end of which extends to the top of the fermentation dustpan 12, and the other end of which extends to the top of the glass 13 on the loading station, and the sampling mechanism 3 is used to extract the tea leaves in the fermentation dustpan 12 into the glass 13; The sampling mechanism 3 is also provided with a camera 15, which is used to take pictures of the tea leaves in the fermentation dustpan 12 so that the staff can check the color of the tea leaves; The monitoring frame 1 is also equipped with a power mechanism 6, one end of which 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 baskets 12, so as to detect the tea leaves in different fermentation winnowing baskets 12.

[0030] The tea leaves to be fermented are placed in the fermentation dustpan 12 for fermentation, and then the power mechanism 6 regularly drives the sliding frame 5 to move, so that the sampling mechanism 3 moves to the top of multiple fermentation dustpans 12 in turn, and takes pictures so that the staff can monitor the tea leaves in real time. When the color of the tea leaves is fermented to meet the requirements, or approximately meets the requirements, the sampling mechanism 3 is started, and the sampling mechanism 3 extracts the tea leaves in each fermentation dustpan 12 and sends the sample to the glass 13. The third servo motor 83 drives the work station plate 81 to rotate one station, and the brewing component 7 adds hot water to the glass 13 to soak the tea leaves in the water. Then the third servo motor 83 drives the work station plate 81 to rotate one station again, so that the glass 13 falls into the recessed area, and then the color of the tea water is detected by the spectrometer 10 to make the tea fermentation data more accurate, so as to assist the staff in making judgments, thereby improving the quality of tea fermentation.

The water tank 71 is filled with water, and a heating device is provided at the inner bottom of the water tank 71 to heat the water.

[0032] like Figure 1-Figure 7As shown, a tea fermentation degree monitoring device provided by the present invention is provided. In this embodiment, the sampling mechanism 3 includes a lifting cylinder 32 that penetrates and is slidably mounted on the sliding frame 5, one end of the lifting cylinder 32 is fixedly connected to a mounting shell 37, a switching disk 312 and a rotating disk 313 are rotatably mounted inside the mounting shell 37, a connecting pipe 314 is fixedly mounted on the switching disk 312, a material taking channel 315 connected to the connecting pipe 314 is opened inside the switching disk 312, a plurality of sampling tubes 39 that can be respectively connected to the material taking channels 315 are fixedly connected to the bottom of the rotating disk 313, the plurality of sampling tubes 39 are evenly distributed around the axis of the rotating disk 313, and the distances of the plurality of sampling tubes 39 from the axis of the rotating disk 313 increase successively, so that the tea leaves within the range of the fermentation dustpan 12 can be stirred and sampled; One end of the connecting tube 314 is connected to a fixed inner tube 311 through a rotating joint, one end of the fixed inner tube 311 passes through the lifting cylinder 32 and is connected to a material delivery hose 31, one end of the material delivery hose 31 is connected to a discharge pipe 33, the discharge pipe 33 is fixedly mounted on the sliding frame 5, and one end of the discharge pipe 33 extends to the top of a glass 13; The sliding frame 5 is fixedly mounted with an air pump 35, the air inlet of the air pump 35 is connected with an air suction pipe 34, one end of the air suction pipe 34 is connected with the discharge pipe 33, and a filter screen 94 is provided at the port of the air suction pipe 34 located inside the discharge pipe 33 to prevent tea leaves from falling into the air 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 air pump 35 away from the lifting cylinder 32; The sliding frame 5 is also fixedly mounted with a first telescopic rod 36, and the movable end of the first telescopic rod 36 is fixedly connected to the lifting cylinder 32 through a connecting plate; The sampling mechanism 3 further includes a driving mechanism 4 , which is mounted on the mounting shell 37 , and is used to drive the rotating disk 313 or the switching disk 312 to rotate.

[0033] When sampling, the first telescopic rod 36 drives the lifting cylinder 32 to descend, and 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 dustpan 12, and 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 evenly mixed, and then the first telescopic rod 36 drives the sampling tube 39 to rise, so that the sampling tube 39 leaves the tea leaves, and 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, and the vacuum pump 35 is started and closed. The electromagnetic valve 310 and the vacuum pump 35 extract the tea leaves in the fermentation dustpan 12 through the sampling tube 39. When the tea leaves are sucked into the discharge tube 33, the power supply of the vacuum pump 35 is cut off and the electromagnetic valve 310 is opened. Under the action of gravity, the tea leaves in the discharge tube 33 will slide into the glass cup 13. When it is judged that the tea leaves have reached the discharge tube 33, an infrared sensor can be used.

The device can perform multiple groups of detection experiments to complete the comparison, so as to more accurately determine the fermentation degree and improve the quality of tea leaves.

[0034] When the driving mechanism 4 drives the rotating disk 313 to rotate, the rotating disk 313 can stir the tea leaves in the fermentation dustpan 12 through the sampling tube 39 to turn the tea leaves over. Before the fermentation is completed, it can replace the staff to regularly turn the tea leaves over, thereby reducing the workload of the staff. After the fermentation is completed, the tea leaves with different fermentation degrees in the fermentation dustpan 12 can be evenly mixed, thereby improving the sample quality and avoiding large errors in the detection data.

[0037] like Figure 4-Figure 6 As shown in the figure, a tea fermentation degree monitoring device provided by the present invention is provided. 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 rotates, the material collection channel 315 and all the sampling tubes 39 may be disconnected, so that the device cannot operate normally and may need to be manually adjusted by the staff.

[0039] like Figure 3-Figure 5 and Figure 7As shown, a tea fermentation degree monitoring device provided by the present invention is provided. 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 3163, so that the material collection channel 315 cannot be connected with different sampling tubes 39, and sampling at different positions cannot be achieved.
