Embodiment 1

[0028] A processing method of black tea, the method comprises the following steps:

[0029] a. Leaf selection and pretreatment: select fresh leaves with one bud and one leaf or one bud and two leaves as raw materials, and carry out sun-drying treatment on the fresh leaves. The time for sun-drying treatment is 1 hour, and the tea leaves lose weight by 2% after sun-drying is completed;

[0030] b, withering: the fresh leaves that have been sun-dried are directly put into the withering tank for hot-air withering, the temperature of hot-air withering is controlled at 20°C, the withering time is 10h, and the water content of the tea leaves after withering is 86%;

[0031] c. Kneading: Put the withered tea leaves into a kneading machine for kneading. The kneading is carried out three times. The first kneading time is 15 minutes. After standing for 3 minutes, the second kneading is carried out. The time is 30 minutes, and after standing still for 5 minutes, the third rolling is carri...

Embodiment 2

[0039] A processing method of black tea, the method comprises the following steps:

[0040] a. Leaf selection and pretreatment: choose fresh leaves with one bud and one leaf or one bud and two leaves as raw materials, and dry the fresh leaves for 1.5 hours. After drying, the weight of the tea leaves will decrease by 3%. ;

[0041] b, withering: put the fresh leaves that have been sun-dried directly into the withering tank for hot air withering, the temperature of hot air withering is controlled at 22.5°C, the withering time is 12h, and the water content of the tea leaves after withering is 84%;

[0042] c. Kneading: Put the withered tea leaves into a kneading machine for kneading. The kneading is carried out three times. The first kneading time is 15 minutes. After standing for 3 minutes, the second kneading is carried out. The time is 30 minutes, and after standing still for 5 minutes, the third rolling is carried out. After rolling for 10 minutes, the cell destruction rate ...

Embodiment 3

[0050] A processing method of black tea, the method comprises the following steps:

[0051] a. Leaf selection and pretreatment: select fresh leaves with one bud and one leaf or one bud and two leaves as raw materials, and carry out sun-drying treatment on the fresh leaves. The time for sun-drying treatment is 2 hours, and the tea leaves lose weight by 4% after sun-drying is completed;

[0052] b, withering: the fresh leaves that have been sun-dried are directly put into the withering tank for hot-air withering, the temperature of hot-air withering is controlled at 25°C, the withering time is 14h, and the water content of the tea leaves after withering is 82%;

[0053] c. Kneading: Put the withered tea leaves into a kneading machine for kneading. The kneading is carried out three times. The first kneading time is 15 minutes. After standing for 3 minutes, the second kneading is carried out. The time is 30 minutes, and after standing still for 5 minutes, the third rolling is carr...

Abstract

The invention discloses a processing method of black tea. The method comprises the following steps: selecting leaves and pre-treating; withering; rolling; fermenting; removing moisture; shaping; drying; improving aroma; and screening. According to the processing method, moisture in intercellular spaces of the tea leaves is evaporated through stomas and horny layers through sun withering treatment, so that leaf textures become soft and subsequent withering and rolling treatment can be conveniently carried out; in a rolling process, a light-strong-light rolling manner is adopted and the cell disruption rate of the tea leaves can be effectively improved to be more than 91%, leaf tissues are sufficiently damaged and a foundation is laid for shaping; the processing method can be used for shaping the tea leaves into a spherical shape so that the appearance of the tea leaves is relatively exquisite and the tea leaves are convenient to fetch; after the tea leaves are subjected to strict temperature-control fermentation, the aroma is primarily extracted; and after the steps of drying and improving the aroma, the black tea which has the characteristics of rich aroma, rich taste, red and bright soup color and the like can be prepared.
