Embodiment 1

[0027] A black hair tea fermentation process comprises the steps of:

[0028] S1 Picking: pick black hair tea, and select, remove impurities, and set aside;

[0029] S2 Humidification: Humidify the spare black-mao tea with water, and the humidification ratio is controlled at 10%. Because the raw materials of black-mao tea are thick and old, the moisture content is low, and the leaf quality is hardened, the raw materials of fresh leaves are generally treated with water. , in order to increase the water content of Heimao tea, emit a special fragrance, the stems are broken and continuous, the leaves are soft and slightly sticky;

[0030] S3 fermentation: steam-heat the black hair tea in step S2, steam heat and ferment the black hair tea through the fermentation chamber, which is convenient to use, the steam heating fermentation temperature is 180°C, and the steam heating fermentation time is 1.5h, and the fermentation temperature can be Effectively control the enzyme activity in...

Embodiment 2

[0037] A black hair tea fermentation process comprises the steps of:

[0038] S1 Picking: pick black hair tea, and select, remove impurities, and set aside;

[0039] S2 Humidification: Humidify the spare black-mao tea with water, and the humidification ratio of the humidified water is controlled at 15%. Since the raw materials of black-mao tea are thick and old, the moisture content is low, and the leaf quality is hardened, the raw materials of fresh leaves are generally treated with water. , in order to increase the water content of Heimao tea, emit a special fragrance, the stems are broken and continuous, the leaves are soft and slightly sticky;

[0040] S3 fermentation: steam heating the black hair tea in step S2, and steam heating and fermenting the black hair tea through the fermentation chamber, which is convenient to use. The steam heating fermentation temperature is 200°C, and the steam heating fermentation time is 2h. Through the above heating temperature and Time ca...

Abstract

The present invention relates to the technical field of raw dark green tea processing and particularly to a raw dark green tea fermentation technology. Raw dark green tea refers to dark green tea which is not pressed, has thick strips and wide leaves and dark brown and oily color and luster, and is generally used for pressing brick-shaped fuzhuan tea, dark brick tea, flower brick tea, qingzhuan tea and tianjian, gongjian and shengjian packaged in baskets. Dark green tea is special tea in China and deeply loved by consumers due to functions of quenching thirst, preventing cancer, resisting cancer, helping digestion, losing weight, delaying aging, etc. The raw dark green tea fermentation technology comprises the following steps: conducting picking: picking raw dark green tea, also conductingselection and removing impurities for a standby application; conducting humidifying: humidifying the prepared raw dark green tea with water; conducting fermenting: conducting steam heating of the rawdark green tea; conducting pile fermentation: closing steam, stacking the raw dark green tea to a certain height, covering flax fabrics on the stacked raw dark green tea to promote enzyme action of tea leaves, spreading the raw dark green tea, performing non-steam fermentation on the raw dark green tea through a fermentation bin after pile turning-over, and finally performing a drying treatment to prepare the raw dark green tea.

Description

technical field [0001] The invention relates to the technical field of black hair tea processing, in particular to a black hair tea fermentation process.
