Problems solved by technology

In summer and autumn, the average daytime temperature in black tea production areas reaches 35°C or higher, and the temperature is too high during black tea fermentation, which will affect the material transformation in the black tea fermentation process and reduce the quality of black tea.
Therefore, the black tea made by traditional crafts is easy to cause the disadvantages of sour taste, too strong taste, dark soup color and black and dull leaf bottom. The taste is mellow, the aroma is rich in orange sugar, and the bottom of the leaves is bright red

Embodiment 1

[0019] A processing method for black tea, comprising withering, rolling, unblocking, fermenting, drying and packaging, the specific processing steps are as follows,

[0020] (1) Withering Place the fresh leaves under infrared light for 20 minutes, control the surface temperature of the fresh leaves at 32°C, and wither until the water content of the fresh leaves is 90%; then wither at room temperature until the water content of the fresh leaves is 60%. The bulb of described infrared light is 275W, and the distance between described bulb and tealeaves is 40cm;

[0021] (2) Kneading Put the withered fresh leaves into a kneading machine for kneading. The kneading is carried out twice. The first time is light kneading for 30 minutes. For heavy kneading, the time is 30 minutes;

[0022] (3) Deblocking Use a deblocking machine or manually to deblock the twirled fresh leaves to make them loose and not agglomerated;

[0023] (4) Fermentation Put the reshaped and rolled leaves into a ...

Embodiment 2

[0027] A processing method for black tea, comprising withering, rolling, unblocking, fermenting, drying and packaging, the specific processing steps are as follows,

[0028] (1) Withering Place the fresh leaves under infrared light for 50 minutes, control the leaf surface temperature of the fresh leaves at 28°C, and wither until the water content of the fresh leaves is 80%; then wither at room temperature until the water content of the fresh leaves is 62%; The bulb of described infrared light is 275W, and the distance between described bulb and tealeaves is 40cm;

[0029] (2) Kneading Put the withered fresh leaves into a kneading machine for kneading. The kneading is carried out twice. The first time is light kneading for 40 minutes. For heavy kneading, the time is 20 minutes;

[0030] (3) Deblocking Use a deblocking machine or manually to deblock the twirled fresh leaves to make them loose and not agglomerated;

[0031] (4) Fermentation Put the unblocked rolled leaves into ...

Embodiment 3

[0035] A processing method for black tea, comprising withering, rolling, unblocking, fermenting, drying and packaging, the specific processing steps are as follows,

[0036] (1) Withering Place the fresh leaves under infrared light and wither for 30 minutes, control the leaf surface temperature of the fresh leaves at 30°C, and wither until the water content of the fresh leaves is 85%; then wither at room temperature until the water content of the fresh leaves is 70%; The bulb of described infrared light is 275W, and the distance between described bulb and tealeaves is 50cm;

[0037] (2) Kneading Put the withered fresh leaves into a kneading machine for kneading. The kneading is carried out twice. The first time is light kneading for 35 minutes. For heavy kneading, the time is 25 minutes;

[0038] (3) Deblocking Use a deblocking machine or manually to deblock the twirled fresh leaves to make them loose and not agglomerated;

[0039] (4) Fermentation Put the unblocked rolled l...

Abstract

The invention discloses a processing method for black tea, and belongs to the technical field of tea processing. The processing method comprises the steps of withering, rolling, deblocking, fermenting, drying and packaging, wherein picked tea leaves are processed through infrared ray light withering, two times of rolling, reshaping, fermenting, two times of drying and packaging, and the black tea is obtained. The black tea is black bloom in color, heavy and compact in strip, golden red and bright in liquor color, long in aroma, sweet and mellow in taste and brilliant red in leaf bottom.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a processing method of black tea. Background technique [0002] Black tea is a kind of tea with the largest output and sales volume at present. Black tea is a kind of fermented tea leaves. After black tea is brewed, the tea color is rich and gorgeous. Since black tea is one of the most popular teas for the public, in order to improve the yield and quality of black tea, many black tea processing techniques are also increasing. [0003] In the traditional black tea processing technology, sunlight withering is generally adopted in the withering process. Due to the temperature change caused by the limited climate, the produced black tea cannot achieve the consistency of the product, and the quality standardization of all products cannot be achieved. Due to the impact of the weather, rainy weather will disrupt the production plan and even cause tea raw materials to...
