Problems solved by technology
This processing method takes a long time to shape, requiring more than 10 hours, and the labor intensity is high. Each link requires more manual and repeated operations, and more broken tea is produced during the kneading process, and the rate of correct tea is low, resulting in Increased fuel and electricity costs

Embodiment Construction
[0009] Embodiments of the present invention: green tea processing method, the fresh leaves picked are withered in a conventional manner, and the withered leaf A with a moisture content of 70% is obtained; the withered leaf A is processed into blue and green, and the first time of doing green is as follows: 5min, the rotating speed of the greening machine is 28r / min, the withered leaf A gets off the machine when the green fragrance is revealed in the green tube, and stands for 2 hours. The time for greening for the first time is 7 minutes. When the blue and white fragrance of tea dregs is revealed, take it off the machine and let it stand for more than 2 hours to obtain green leaves B with moderate greening; then stir-fry green leaves B at a temperature of 210°C About, the amount of leaf throwing is 2kg, and the time is 5min, and the fried green leaves C with a water content of 51% are obtained; then the fried green leaves C are spread to cool for 2 hours, and then kneaded with ...

The invention discloses a processing method of oolong tea, which comprises the following steps: withering picked fresh leaves in a conventional mode to obtain withered leaves A; carrying out the green-making on the withered leaves A in a conventional mode to obtain green-making leaves B; then roasting the rotated leaves B to obtain roasted leaves C; then after the roasted leaves C are spread and cooled, rolling the roasted leaves C by a green tea rolling machine to obtain tea blank D curled in a strip shape; screening the tea blank D to remove dust tea and putting the tea blank D into a double-pan roasting machine for shaping to obtain tea blank E after shaping; and finally spreading and airing the tea blank E and screening to remove the dust tea, and drying in a dryer to sufficient dry to obtain the finished product. The invention improves the traditional oolong tea processing, when the oolong tea is processed, kneading is omitted in shaping, but shaping is carried out by a stir roasting machine after rolling by the green tea rolling machine, and thus time can be controlled in about 3 hours, thereby greatly reducing the processing time, reducing the labor intensity of workers, saving the processing cost and improving the regular tea rate.
Description
technical field [0001] The invention relates to a processing method of tea, in particular to a processing method of green tea. Background technique [0002] Green tea is originally produced in Guangdong, Fujian, and Taiwan provinces. It has quality characteristics different from the other five major teas, namely: green leaves with red edges, and natural floral and fruity fragrance. The traditional process of imported green tea is: withering, greening, roasting, rolling and drying. The key process is greening. The rolling and drying include: bundling, rolling, unblocking and initial drying, repeated more than three times, and then Fix the shape with a cloth ball, and finally dry it. In the traditional method, "kneading" is to use kneading to make the shape, which needs to be repeatedly "bundled, kneaded, unblocked, dried (baked)" to set the shape, and finally baked until it is fully dry. This processing method takes a long time to shape, requiring more than 10 hours, and th...
