Abstract
The invention provides a black tea withering method. The black tea withering method comprises the following steps: 1), picking fresh tea leaves from tea trees, placing the picked tea leaves on a withering shelf, wherein the withering thickness is 0.5-3.5 centimeters and the withering time is 1.5-2.5 hours, and turning the tea leaves for 4-5 times during withering; 2) placing the tea leaves in a withering machine, wherein the spreading thickness of the tea leaves is 40-60 centimeters, and withering the tea leaves by using cold air for 30-45 minutes; 3), carrying out withering by using hot air for 60-80 minutes, wherein the temperature of the hot air is 35-40 DEG C; 4), carrying out withering by using cold air for 50-70 minutes; 5), carrying out withering by using hot air for 30-50 minutes, wherein the temperature of the hot air is 35-40 DEG C; 6) stopping the withering machine for 1 hour; and 7), carrying out withering by using hot air for 130-150 minutes, wherein the temperature of the hot air is 35-40 DEG C. The tea leaves are turned once every 15 minutes during the whole withering processes. The black tea withering method has the advantages of accelerating water loss of the fresh leaves, speeding up internal substance transformation in the fresh tea leaves and so on. By adopting the black tea withering method disclosed by the invention, the tea leaves are uniformly and fully withered; moreover, the withering time is greatly reduced.
Description
Technical field
The invention belongs to tea technology field is and in particular to a kind of black tea deterioration method.
Background technology
Withering is the first procedure of processing processed at the beginning of congou tea, is also the basic operation forming quality of congou black tea.Wither
The dehydration effect of existing physics aspect of withering, also has the process of the chemical change of internal substance.Tea fresh leaves pass through to wither, main generation
Two aspect change below：One is evaporation section moisture, reduces the tension force of tea fresh leaves cell, makes leaf, stalk soft by embrittlement, increases bud-leaf
Toughness, be easy to knead into bar；Two is to cause a series of chemical changes of the internal substance in the tea tip due to scattering and disappearing of moisture,
Certain quality for forming black tea color establishes the basis of material change.The grasp of withering degree, to tea-making quality and after
Continuous activity relation is very big.As deficiency of withering, fresh leaf cell tense situation does not eliminate, and the food value of leaf is hard and crisp, and when kneading, bud-leaf is easily broken broken,
Tea juice is thin to be easy to run off, and fermentation is uneven, makes the short broken multi-disc end of raw tea bar rope, and fragrant low taste is not mature, soup look muddy, and leaf bottom is spent miscellaneous
Band is blue or green；As withered excessively, bud milli is dried-up, and the food value of leaf is stiff, and when kneading, tea juice does not go out, and is difficult tightly to roll up, and fermentation is irregular, and raw tea pine bubble is many
Flat bar, color and luster ash is withered not to show milli, and fragrance is thin, and soup look, leaf bottom are secretly miscellaneous.Therefore, withering must be appropriate, and excessive and deficiency is all to hair
Tea quality is unfavorable.
Content of the invention
The invention provides a kind of black tea deterioration method.
The present invention provides a kind of black tea deterioration method, and step is as follows：
1）Pluck fresh, undamaged fresh leaf of Camelliae sinensis, place and wither on frame, wither thickness 0.5cm-3.5cm, withering time 1.5
Hour -2.5 hours, stirs 4-5 time halfway；
2）Folium Camelliae sinensis are placed in deteriorating machine and wither, Folium Camelliae sinensis spread thickness 40-60cm, cold wind to wither 30-45min；
3）Hot blast withers 60-80min, 35-40 DEG C of hot blast temperature；
4）Cold wind to wither 50-70min；
5）Hot blast withers 30-50min, 35-40 DEG C of hot blast temperature；
6）Shut down 1 hour；
7）Hot blast withers 130-150min, 35-40 DEG C of hot blast temperature；In process of entirely withering, every 15 minutes, Folium Camelliae sinensis are stirred
Once.
Preferably, step is as follows： 1）Pluck fresh, undamaged fresh leaf of Camelliae sinensis, place and wither on frame, wither thickness
2cm, withering time 2 hours, stirs 4 times halfway；
2）Folium Camelliae sinensis are placed in deteriorating machine and wither, Folium Camelliae sinensis spread thickness 50cm, cold wind to wither 40min；
3）Hot blast withers 70min, 38 DEG C of hot blast temperature；
4）Cold wind to wither 60min；
5）Hot blast withers 40min, 38 DEG C of hot blast temperature；
6）Shut down 1 hour；
7）Hot blast withers 140min, 38 DEG C of hot blast temperature；In process of entirely withering, every 15 minutes, Folium Camelliae sinensis are stirred once.
The present invention has the advantages that quickening fresh leaf dehydration, quickening fresh leaf internal substance convert, using the inventive method, Folium Camelliae sinensis
Wither uniform, abundant；Meanwhile, significantly shorten withering time.
