Example Embodiment

[0015] Example 1: A processing method of fermented black tea, including the leaf selection and spreading process, withering process, rolling process, fermentation process and drying process. The specific operations are as follows:

[0016] a. Leaf selection and stall drying process: Pick fresh tea leaves from big tree tea with one bud and two leaves or one bud and three leaves in a tea garden at an altitude of 800 meters, and place the fresh leaves on a drying rack with a thickness of 2 ~5cm, hang out for 0.50~1h in weak sunlight;

[0017] b. Withering process: place the tea leaves that have been selected and dried in a withering trough for hot air withering, the hot air temperature is 40~60℃, withering time is 1~4h, and withered leaves are obtained;

[0018] d. Kneading process: Put the withered leaves that have gone through step b into the kneading machine, and form them after three times of kneading. When empty kneading, put the withered leaves on the kneading machine, and knead t...

Abstract

The invention discloses a processing method of fermented black tea. The processing method comprises the following steps of performing withering; performing empty twisting, wherein the pressure is 0N during empty twisting; performing heavy twisting: spraying complex enzyme fluid while performing twisting during heavy twisting, wherein the twisting pressure is 70-120N; performing light twisting, wherein the twisting pressure is reduced to 20-30N during light twisting; performing water surface fermentation: performing fermentation in a fermenting box made of Chinese birch wood materials during the water surface fermentation, during fermentation, laying a gauze which is wet by being soaked in sterile water at the bottom of the fermenting box, placing twisted leaves on the gauze, performing covering with a fermenting cover, placing the fermenting box in flowing warm water of 25-35 DEG C, performing fermentation for 4-6h, and conveying the fermented tea leaves into a drying box; and performing drying: performing drying in the drying box so as to obtain finished products. According to the processing method disclosed by the invention, a twisting working procedure and a fermentation working procedure are optimized, so that the rupture rate of cell walls is further enlarged, more tea liquor and tea leaf inclusions flow out, the fermentation effect of the tea leaves is guaranteed, after being brewed, the made black tea is attractive in soup color, mellow in mouth feel and sweet after taste, and the fermented black tea is highest-grade black tea among all of the black tea.

Description

technical field [0001] The invention belongs to the technical field of tea processing, in particular to a processing method of fermented black tea. Background technique [0002] Black tea is a fully fermented tea. Because the dry tea, soup color, and leaf bottom are mainly red, it is named black tea. According to the corresponding clinical research in my country, tea pigments, the important substances that constitute its unique flavor, play a role in regulating blood lipids, anti-lipid peroxidation, eliminating free radicals, anticoagulation and promoting fibrinolysis. [0003] There are many varieties of black tea in China, mainly including: Rizhao black tea, Qihong, Zhaopinghong, Huohong, Dianhong, Yuehong, Quancheng red, Quancheng green, Suhong, Chuanhong, Yinghong, Dongjiang Chuyunxian black tea, etc. Keemun black tea is the most famous. Regarding the processing of black tea, it is a tea made from the young buds and leaves of tea trees as raw materials, through witheri...
