Embodiment 1

[0047] A processing method of black tea, which sequentially includes the following specific steps:

[0048] 1) Raw material selection and picking

[0049] Raw material: The variety is selected as Bayu special early. The raw materials are collected from a pollution-free ecological tea garden at an altitude of 550-650m. The picking requires a sunny temperature of 25°C. The standard for picking is one bud and one leaf, the length of bud and leaf is 2.5~2.8cm, bud and leaf are intact and even, there are no purple leaves, fish leaves, diseased leaves, etc.

[0050] 2) Withering

[0051] Withering: Under the condition that the outdoor temperature is lower than 30℃, the fresh leaves are evenly spread on the withering curtain or dustpan, and the spreading amount of leaves is 0.5kg / m 2 After drying for 10min, then transfer to the room to continue withering. The indoor temperature is 20℃, the relative humidity is 65%, and the thickness is 5cm to make the leaf layer loose and breathable. After ...

Embodiment 2

[0064] A processing method of black tea, which sequentially includes the following specific steps:

[0065] 1) Raw material selection and picking

[0066] Raw material: Select Shuyong No. 1 as the variety. The raw materials are collected from a pollution-free ecological tea garden at an altitude of 550-650m. The picking requires a sunny temperature of 25°C. The standard for picking is one bud and one leaf, the length of bud and leaf is 2.5~2.8cm, bud and leaf are intact and even, there are no purple leaves, fish leaves, diseased leaves, etc.

[0067] 2) Withering

[0068] Withering: Under the condition that the outdoor temperature is lower than 30℃, the fresh leaves are evenly spread on the withering curtain or dustpan, and the spreading amount of leaves is 0.6kg / m 2 After drying for 15min, then transfer to the room to continue withering. The indoor temperature is 25℃, the relative humidity is 75%, and the laying thickness is 10cm to make the leaf layer loose and breathable. After la...

Embodiment 3

[0079] A processing method of black tea, which sequentially includes the following specific steps:

[0080] 1) Raw material selection and picking

[0081] Raw material: select Sichuan small leaf species. The raw materials are collected from a pollution-free ecological tea garden at an altitude of 550-650m. The picking requires a sunny temperature of 23°C. The standard for picking is one bud and one leaf, the length of the bud and leaf is 2.5cm, the bud and leaf are intact and even, and there are no purple leaves, fish leaves, pest leaves, etc.

[0082] 2) Withering

[0083] Withering: Under the condition that the outdoor temperature is lower than 30℃, the fresh leaves are evenly spread on the withering curtain or dustpan, and the spreading amount of leaves is 0.6kg / m 2 After drying for 10 minutes, then transfer to the room to continue withering. The indoor temperature is 25℃, the relative humidity is 70%, and the thickness is 7cm to make the leaf layer loose and breathable. After spr...

Abstract

A method for processing black tea, which sequentially includes: raw material selection and picking, withering, rolling, fermentation, shaping, and baking. The rolling is to fill the kneading barrel with withered leaves, knead them empty for 20-25 minutes, and then lightly press them for 20-20 minutes. 25min, heavy pressing for 25-30min, light pressing for 10-15min, empty kneading for 5min, and tea out, with a total kneading time of 80-100min; the black tea obtained by the black tea processing method of the present invention has a tight, thin and straight shape, a black color, and a golden Revealed, the soup is bright red, sweet and pure, the taste is mellow and sweet, the bottom of the leaf is red and bright, even and complete, the shape of the dry tea is straight and strong, the color of the tea soup is bright red, the aroma is strong and sweet, the soup is rich and red Bright, fresh and intense.

Description

Technical field [0001] The invention relates to a tea processing technology, in particular to a processing method of high-quality black tea. Background technique [0002] Black tea is a fully fermented tea, which is refined by processing techniques such as withering, rolling, fermenting, and drying the fresh leaves of the tea tree. Because the dry tea, soup color, and leaf base are all red in color, it is named black tea. [0003] Corresponding clinical studies in my country have shown that tea pigments, an important substance that constitutes its unique flavor, play a role in regulating blood lipids, anti-lipid peroxidation, eliminating free radicals, anti-coagulation and promoting fibrinolysis. [0004] At present, many black teas cannot be stable in quality due to insufficient raw materials or processing techniques. Dry tea is loose in appearance and grayish brown in color; when the tea is formed, the color is dark and not red; the taste is bitter, which is difficult to meet the ...
