Problems solved by technology

[0002] Now the fermentation of black tea is mainly carried out under constant temperature and humidity, and the tea leaves are placed in a stable container, so that the tea leaves inside and outside the tea fermentation pile produced in this way are unevenly fermented, the content of theaflavins is not high, and the taste of the produced black tea is not fresh. , the soup color is less red, and the quality of the same batch of tea is uneven

Embodiment 1

[0031] Black tea fermentation process step of the present invention is as follows:

[0032] Put 100kg of withered and moderately rolled black tea greens into a fermenter placed horizontally, and gently rotate the black tea in the fermenter at a frequency of 1 revolution / 2min to ensure the temperature, humidity and oxygen contact of tea inside and outside the pile. The probability of all the same, while rotating, adjust the temperature: within the temperature range of 30°C to 20°C, successively decrease and change the temperature to ferment, the specific variation law of the temperature in the fermentation process is shown in Table 1, and the black tea of ​​the present invention is obtained after the fermentation is completed.

[0033] Table 1

[0034] .

[0035] The black tea obtained by applying the above method is evenly fermented, and the quality of the same batch of tea leaves is uniform. Compared with the control sample fermented at constant temperature for 150 minutes...

Embodiment 2

[0045] Black tea fermentation process step of the present invention is as follows:

[0046] Put 100kg of withered and moderately rolled black tea greens into a horizontally placed fermenter, and gently rotate the black tea in the fermenter at a frequency of 1 revolution / 1min to ensure that the temperature, humidity and oxygen contact between the inside and outside of the tea pile The probability of the temperature is the same, while rotating, adjust the temperature: in the temperature range of 30°C to 20°C, successively decrease and change the temperature to ferment, the specific variation law of the temperature in the fermentation process is shown in Table 3, and the black tea of ​​the present invention is obtained after the fermentation is completed.

Embodiment 3

[0050] Black tea fermentation process step of the present invention is as follows:

[0051] Put 100kg of withered and moderately rolled black tea greens into a horizontally placed fermenter, and gently rotate the black tea in the fermenter at a frequency of 1 revolution / 5min to ensure that the temperature, humidity and oxygen contact of the tea leaves inside and outside the pile The probability of all the same, while rotating, adjust the temperature: within the temperature range of 30 ℃ to 20 ℃, successively decrease and change temperature fermentation, the specific variation law of temperature in the fermentation process is shown in Table 4, and the black tea of ​​the present invention is obtained after the fermentation is completed.

Abstract

The invention provides a black tea fermentation process, which is to turn the black tea leaves that have been withered and rolled moderately, and at the same time, within the temperature range of 30°C to 20°C, successively decrease and change temperature fermentation to prepare black tea. Therefore, the present invention also provides a fermenter specially used for black tea fermentation. The tea leaves produced by the process of the invention are evenly fermented, and the obtained black tea soup has bright red color and fresh taste, and the quality of the same batch of tea leaves is uniform, and the sensory evaluation score is higher than that of the black tea fermented at constant temperature.

Description

technical field [0001] The invention relates to a black tea fermentation process and a special fermenter for black tea fermentation. Background technique [0002] Now black tea fermentation is mainly carried out under constant temperature and humidity, and the tea leaves are kept in a stable container, so the tea leaves inside and outside the tea fermentation heap produced in this way are unevenly fermented, the content of theaflavins is not high, and the taste of the produced black tea is not fresh. , the soup color is less red, and the quality of the same batch of tea is uneven. Contents of the invention [0003] The invention provides a black tea fermentation process. The tea leaves produced by the process are evenly fermented, and the obtained black tea soup has bright red color, fresh taste and uniform quality of the same batch of tea leaves. The sensory evaluation score is higher than that of constant temperature fermented black tea. Therefore, the present inventio...
