Black tea drying method

Abstract

The invention provides a black tea drying method which comprises the following steps: (1) tea leaves are put into a dryer, and the spreading thickness is 8-10 cm; (2) the tea leaves are dried for 10-15 min for the first time at the control temperature of 130 DEGC; (3) the tea leaves are dried for 10-15 min for the second time at the control temperature of 120 DEG C; (4) the tea leaves are taken out from the dryer, and are cooled for 30-40 min after being spread; (5) the tea leaves are put into the dryer again and dried for 6-10 min for the third time at the control temperature of 80 DEG C. In the first-time drying, the tea leaves are quickly dried at the high temperature to remove the enzymatic oxidation effect rapidly, and the lower the temperature is and the longer the time is, the larger the damage to the quality is; in the second-time drying, the tea leaves are dried at the slightly low temperature to eliminate the damp and hot effects rapidly, and after being dampened and heated again, the tea leaves are darken in color, mild in taste, and weak in fragrance; after the second-time drying, the tea leaves are cooled after being spread, and the tea leaves with non-uniform moisture are wetted back during the drying process; in the third-time drying, the tea leaves are dried slowly at the low temperature to avoid being over-fired and facilitate the formation of black tea fragrance. The method can uniformly and completely dry the black tea, and the fragrance of the tea leaves is strong.

Description

technical field [0001] The invention relates to a method for drying black tea. Background technique [0002] The traditional black tea drying method adopts two drying processes of the dryer, the main fire and the full fire. The main fire controls the temperature at 110°C-120°C for 10 minutes; the full fire is 85°C-95°C for 15 minutes. Although this drying method takes a short time, the drying is uneven and insufficient, and the aroma of the tea leaves is insufficient. Contents of the invention [0003] The invention proposes a drying method for black tea, and the technical problem to be solved is mainly to solve the problems of uneven and insufficient drying and insufficient aroma of tea leaves. [0004] For this reason, the technical scheme of the present invention is: a kind of drying method of black tea, specifically: [0005] (1) Put the tea leaves in the dryer and spread out the thickness of 8-10 cm; [0006] (2) One drying: control the temperature at 130°C for 10-...
