Description

Technical Field

[0002] Yellow tea is one of the six basic teas in my country. It has a long history, multiple origins, rich categories and different qualities. Yellow tea is slightly fermented tea. The main production processes include killing green, steaming and drying. Steaming is particularly important. It is an important step in forming the quality characteristics of yellow tea. The degree of steaming and the control of steaming also determine the quality of yellow tea. Good yellow tea is hard to find on the market because it is difficult to master the steaming step. In fact, the steaming process is the fermentation process. In this process, chlorophyll and other substances in the leaves are oxidized, and the color of the tea leaves turns yellow. Yellow leaves and yellow soup are the distinctive characteristics of yellow tea. Compared with green tea, the taste of yellow tea is not as bitter as green tea, and it is more mellow.

[0037] In this embodiment, refer to Figure 2 and Figure 3 and Figure 6The second motor 16 is installed on the side wall of the second vertical support column 13. The second motor 16 will drive the small pulley 17 to rotate. Under the action of the belt 18, the large pulley 19 installed on the surface of the rotating rod 15 can be rotated, thereby driving the rotating rod 15 to rotate. The side surface of the rotating rod 15 is fixedly connected to the connecting block 23, and then the end of the connecting block 23 is connected to the kneading cylinder 29. At this time, the rotating rod 15 can drive the kneading cylinder 29 to draw a circle on the upper surface of the disc 27. The withered tea leaves fall into the kneading cylinder 29 from the discharge hopper 12. A pressure sensor 49 is provided at the bottom of the kneading cylinder 29. The pressure sensor 49 transmits data to the controller, thereby controlling the operation of the second motor 16. At the same time, the tea leaves falling into the kneading cylinder 29 fall onto the disc 27 from the discharge port 48 at the bottom of the kneading cylinder 29.

[0038] In this embodiment, refer to Figure 2 and Figure 4 An inclined leg 34 is fixedly installed on the upper end surface of the horizontally placed base 1, and a drying cylinder 35 is fixedly installed on the upper end surface of the inclined leg 34, and a heating plate 39 is arranged inside the drying cylinder 35. The heating plate 39 is used to heat the inside of the drying cylinder 35, so that the rolled tea leaves are suffocated. At the same time, an isolation cylinder 40 is arranged inside the drying cylinder 35. The tea leaves will be inside the isolation cylinder 40 to prevent direct contact between the tea leaves and the heating plate 39, thereby preventing the tea leaves from being fried and scorched.

[0039] In this embodiment, refer to Figure 3 and Figure 4 The L-shaped connecting rod 37 is fixed by the second vertical support column 13, and then the third motor 38 is fixedly supported. The rotation of the third motor 38 is controlled by the controller, so that the rotating shaft 36 at the kinetic energy output end of the third motor 38 rotates, and the side wall of the rotating shaft 36 is fixedly connected to the stirring rod 41. The stirring rod 41 can be used to stir the tea leaves inside the isolation cylinder 40 to ensure uniform heating, and a second temperature sensor 50 and a color sensor 51 are installed on both sides of the stirring rod 41.

[0041] The present invention also provides a fully automatic yellow tea intelligent production method, which specifically comprises the following steps:

[0042] The external power supply is turned on, and the controller is used to control the first motor 3 to work. Through the meshing action of the small gear 5 and the large gear 4, the threaded rod 7 is rotated. Under the action of the threaded rod 7 and the vertical long groove 6, the limit block 8 and the placement bin 10 can be moved up and down. When it moves downward to a certain position, it is convenient to put the tea leaves that need to be sterilized into the placement bin 10. The next step is to control the heating temperature inside the heating water tank 20 through the controller, and the generated water vapor enters the placement bin 10 from the air outlet pipe 21 to heat and sterilize the tea leaves. Then, the first temperature sensor 47 inside the placement bin 10 is used to measure the temperature in real time, so as to ensure that the sterilization is at a suitable temperature. After the sterilization is completed, the second electric push rod 30 is used to control the opening and closing of the packaging plate 11 and the bottom of the placement bin 10, so as to facilitate the sterilized tea leaves to flow from the discharge hopper 12 into the rolling cylinder 29.

[0043] A pressure sensor 49 is provided at the bottom of the kneading cylinder 29. When the tea leaves fall onto the pressure sensor 49, the pressure sensor 49 transmits data to the controller, thereby controlling the operation of the second motor 16. The second motor 16 drives the small pulley 17 to rotate. Under the action of the belt 18, the large pulley 19 installed on the surface of the rotating rod 15 can rotate, thereby driving the rotating rod 15 to rotate. The rotating rod 15 can drive the kneading cylinder 29 to draw a circle on the upper surface of the disc 27. The tea leaves fall onto the disc 27 from the discharge port 48 inside the kneading cylinder 29. Through the action of the large pattern 28 and the small pattern 26, the tea leaves can be kneaded very conveniently and evenly, which is convenient for the subsequent steps. The kneading time is controlled, and the first electric push rod 24 is opened. The round cake 25 is separated from the disc 27 to form a gap, and then enters the roasting cylinder 35 from the discharge trough 33.

[0044] The rotation of the third motor 38 is controlled by a controller, thereby driving the rotating shaft 36 at the kinetic energy output end of the third motor 38 to rotate, and the side wall of the rotating shaft 36 is fixedly connected to the stirring rod 41. The stirring rod 41 can be used to stir the tea leaves inside the isolation cylinder 40 to ensure uniform heating, and a second temperature sensor 50 and a color sensor 51 are installed on both sides of the stirring rod 41. The second temperature sensor 50 can monitor the internal temperature of the roasting cylinder 35 to prevent the temperature from being too high, and the color sensor 51 can be used to detect the yellowing tea leaves to ensure the yellowing effect, and the tea leaves can be taken out and collected after the yellowing is completed.
