Abstract

The invention provides a withering method for black tea. The withering method specifically comprises the following steps: placing tea leaves into a withering machine and withering the tea leaves; paving the tea leaves according to the thickness of 40-60 centimeters; firstly, withering by cold air for 2-3 hours and withering by hot air for 1-2 hours, wherein the temperature of the hot air is 35-40 DEG C; stopping the machine for 1 hour; withering by the hot air for 1-2 hours, wherein the temperature of the hot air is 35-40 DEG C; and in the whole withering process, overturning the tea leaves for one time every 15 minutes. According to the withering method for the black tea, an existing withering machine is used for withering and is mechanically operated and the effect is improved; the specific withering time of the cold air and the hot air is set; firstly, the withering is carried out by the cold air and the tea leaves are prevented from being withered too fast, the withering time is short and the physicochemical changes are intense; bud tips and leaf margins are prevented from being withered, and are prevented from even becoming red; then the tea leaves are sufficiently withered by using hot air, and the hot air withering can effectively guarantee that the tea leaves are uniformly and sufficiently withered; meanwhile, the withering time is greatly shortened.

Description

technical field

[0001] The invention relates to the field of tea production, in particular to a method for wilting black tea. Background technique

[0002] In the production process of black tea, the traditional method of withering is carried out indoors under natural climate conditions. About 18 hours, adjust the temperature and humidity by opening and closing doors and windows.

[0003] The problems of this method are: the withering time is long, the withering is uneven, and the withering is not sufficient. Contents of the invention

[0004] The invention proposes a black tea withering method, which mainly solves the problems of long withering time, uneven withering, and insufficient withering in the withering process, achieves the purpose of uniform and sufficient withering, and greatly shortens the withering time .

[0005] For this reason, the technical scheme of the present invention is: a kind of withering method of black tea, specifically:

[0006] Put the tea ...
