Embodiment 1

[0028] The present embodiment provides a kind of processing method of black tea, specifically comprises the following steps:

[0029] (1) Tea screening: use a sieve to filter and screen the newly picked tea leaves to obtain tea leaves with uniform sizes;

[0030] (2) Withering: Spread the screened tea leaves evenly in the withering trough with a thickness of 4cm. The withering trough for spreading the tea leaves is withered by two-way air blowing by a two-way blower, and red light with a wavelength of 560mm is used above the withering trough. Monochromatic light irradiation, control the distance between the lamp tube and the surface of the spread leaf ≦ 13cm, and the withering time is 3 hours;

[0031] (3) kneading: kneading the tea leaves processed in step (2) on a kneading machine, the kneading time is 1 hour, after kneading ends, the tea leaves are manually unblocked;

[0032] (4) Spraying nutrient solution: the nutrient solution with a temperature of 45° C. is evenly spra...

Embodiment 2

[0038] The present embodiment provides a kind of processing method of black tea, specifically comprises the following steps:

[0039](1) Tea screening: use a sieve to filter and screen the newly picked tea leaves to obtain tea leaves with uniform sizes;

[0040] (2) Withering: spread the screened tea leaves evenly in the withering trough with a thickness of 7cm. The withering trough for spreading the tea leaves is withered by two-way air blowing by a two-way blower, and red light with a wavelength of 590mm is used above the withering trough. Monochromatic light irradiation, control the distance between the lamp tube and the surface of the spread leaves ≦ 13cm, and the withering time is 3.5 hours;

[0041] (3) kneading: kneading the tealeaves processed through step (2) on a kneading machine, the kneading time is 1.2 hours, after kneading, the tea leaves are manually unblocked;

[0042] (4) Spraying nutrient solution: the nutrient solution with a temperature of 50° C. is evenly...

Embodiment 3

[0048] The present embodiment provides a kind of processing method of black tea, specifically comprises the following steps:

[0049] (1) Tea screening: use a sieve to filter and screen the newly picked tea leaves to obtain tea leaves with uniform sizes;

[0050] (2) Withering: Spread the screened tea leaves evenly in the withering trough with a thickness of 9cm. The withering trough for spreading the tea leaves is withered by two-way air blower in two directions, and red light with a wavelength of 620mm is used above the withering trough. Monochromatic light irradiation, control the distance between the lamp tube and the surface of the spread leaves ≦ 13cm, and the withering time is 4 hours;

[0051] (3) kneading: kneading the tea leaves processed through step (2) on the kneading machine, the kneading time is 1.5 hours, after kneading, the tea leaves are manually unblocked;

[0052] (4) Spraying nutrient solution: the nutrient solution with a temperature of 55° C. is evenly ...

Abstract

The invention provides a processing method of black tea, and relates to the technical field of processing of tea. The processing method of the black tea comprises the following steps of (1) screeningof tea leaves; (2) withering; (3) rolling; (4) spraying of a nutritional solution; (5) fermenting; (6) preparing of tea soup; (7) spraying of the tea soup; (8) drying. The processing method of the black tea has the advantages that any harmful matter is not added or produced in the raw material and processing process; in the withering process, the bidirectional air blowing type withering is performed by an indoor withering tank for withering and a bidirectional air blower, and the air in the withering tank uniformly flows, so that the tea leaves can be uniformly withered without turnover of thetea leaves; the operation is simple and convenient, the aromatic flavor is heavy and lasting, the health-care effect is better, the labor amount is reduced, and the economic benefit is increased.

Description

【Technical field】 [0001] The invention relates to the technical field of tea processing, in particular to a black tea processing method. 【Background technique】 [0002] Black tea is the main tea consumed in the world. It is widely loved by consumers because of its strong, fresh and refreshing quality and style. Black tea is a precious natural beverage with good beauty and health care effects. It has been proved by scientific analysis and time , black tea contains high amino acids, vitamins, minerals, tea polyphenols and alkaloids, and has a variety of nutritional and medicinal ingredients. Cholesterol, reduce cardiovascular disease and diabetes and other effects. [0003] Withering is an essential process in the tea processing process. The freshly picked tea leaves are withered to make the tea leaves lose moisture and become soft, which is convenient for subsequent processing; at the same time, the activity of enzymes contained in the tea leaves is enhanced. , promote the ...
