Embodiment 1

[0018] Embodiment 1: the processing technology of black tea, comprises 6 operations of leaf selection and airing process, withering process, vacuum microwave treatment process, rolling process, fermentation process and drying process, concrete operations are as follows:

[0019] a. Leaf selection and drying process: pick fresh tea leaves with one bud and two leaves or one bud and three leaves on the big tree tea in a green tea garden above 800 meters above sea level, and place the fresh leaves in a rotating drying tray. The thickness of the spread leaves is 2~3cm, the temperature is 20~26℃, the light intensity is 30000LUX in the outdoor sunlight for 1h, the spreader is rotated every 10min, each time takes 2min, and the tea is thinned and beaten Disperse, so that it can dissipate moisture as soon as possible;

[0020] b. Withering process: place the tea leaves that have been selected and aired in the withering tank for hot air withering, the temperature of the hot air is 30°C, ...

Embodiment 2

[0025] Embodiment 2: the processing technology of black tea, comprises 6 operations of leaf selection and airing process, withering process, vacuum microwave treatment process, rolling process, fermentation process and drying process, concrete operations are as follows:

Abstract

The invention discloses a black tea processing technology which comprises 6 work procedures of a leaf selecting, spreading and airing work procedure, a withering work procedure, a vacuum microwave treatment work procedure, a rolling work procedure, a fermenting work procedure and a drying work procedure. The black tea processing technology specifically comprises the steps: a, the leaf selecting, spreading and airing work procedure: picking fresh tea leaves in a form of two leaves and a bud or three leaves and a bud from camellia arborescens in a green tea garden with altitude of 800 meters or more and putting the fresh tea leaves in a rotary spreading and airing disk to be aired by sunshine; b, the withering work procedure; c, the vacuum microwave treatment work procedure: putting the tea leaves treated in the step b into a vacuum microwave chamber to be treated; d, the rolling work procedure; e, the fermenting work procedure; f, the drying work procedure. According to the black tea processing technology disclosed by the invention, rotary sunshine spreading and airing, vacuum microwave treatment and short-time rolling are combined, so that tea leaf cell disruption rate is improved, tea yield is prevented from being reduced at the same time, and a fermenting effect of tea leaves is ensured; compared with a traditional technology, yield of finished tea products is improved by 10% to 20%, tea shapes are complete, storage life is long, fragrance is strong and durable, and taste is mellow and long.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a black tea processing technology. Background technique [0002] Black tea is a fully fermented tea. Because the dry tea, soup color, and leaf bottom are mainly red, it is named black tea. According to the corresponding clinical research in my country, tea pigments, the important substances that constitute its unique flavor, play a role in regulating blood lipids, anti-lipid peroxidation, eliminating free radicals, anticoagulation and promoting fibrinolysis. [0003] There are many varieties of black tea in China, mainly including: Rizhao black tea, Qihong, Zhaopinghong, Huohong, Dianhong, Yuehong, Quancheng red, Quancheng green, Suhong, Chuanhong, Yinghong, Dongjiang Chuyunxian black tea, etc. Keemun black tea is the most famous. Regarding the processing of black tea, it is a tea made from the young buds and leaves of tea trees as raw materials, through with...
