Effect test

Embodiment 1

[0009] A method for withering black tea, specifically:

[0010] Put the tea leaves in the wilting machine. The thickness of the tea leaves is 40 cm. First, the cold air is withered for 3 hours, and then the hot air is withered for 2 hours. The hot air temperature is 35°C; throughout the wilting process, the tea leaves are turned every 15 minutes.

[0011] Example 1 works best.

Embodiment 2

[0013] Put the tea leaves in the withering machine, spread the tea leaves to a thickness of 60 cm, firstly wither with cold air for 2 hours, then wither with hot air for 1 hour, at a temperature of 40°C, stop the machine for 1 hour, and then wither with hot air for 1 hour. The hot air temperature is 40°C; throughout the wilting process, the tea leaves are turned every 15 minutes.

[0014] Example 2 The shortened time can achieve the goal, but there is no Example 1 The effect is good.

[0015] The technical scheme of the present invention is not limited to Example 1 and Example 2 . As long as it is within the following range, "First cold air withering for 2-3 hours, then hot air for 1-2 hours, hot air temperature 35-40°C, stop for 1 hour, then hot air for 1-2 hours, hot air temperature 35 -40°C;", all should fall within the protection scope of the present invention.

[0016] The innovation of the present invention lies in: the combination of cold air withering, hot air ...

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 ...
