A kind of manufacture craft of jujube black tea
Technical field
The present invention relates to black tea production field, especially a kind of manufacture craft of jujube black tea.
Background technique
Black tea belongs to full fermentation tea, because its dry tea color and brew millet paste with red be homophony due to gain the name.Black tea is rich in recklessly
Radish element, vitamin A, calcium, phosphorus, magnesium, potassium, caffeine, isoleucine, leucine, lysine, glutamic acid, alanine, lucid asparagus
The various nutrient elements such as propylhomoserin, black tea have preventing decayed tooth, the whole intestines of stomach invigorating are aid digestion, delaying aging, hypoglycemic, lowering blood pressure and blood fat,
Anticancer, anti-radiation and other effects;Black tea or splendid sports drink, if being needed other than it can relieve summer heat and quench one's thirst and keep the skin wet

Jujube, protein rich in, fat, sugared part, carrotene, vitamin B, C, P and phosphorus, calcium, iron etc., there is " day
The good reputation of right vitamin pill " has stronger suppression love, anti-allergic effects.Contain cyclic adenosine monophosphate in jujube, muscular strength can be enhanced, disappeared
Except fatigue, expansion blood vessel, increase myocardial contractive power, improvement myocardial nutrition, has good action to prevention and cure of cardiovascular disease.Jujube is also
Energy energy tonic and nourishing, nourishing blood and tranquilization, strengthening the spleen and stomach etc., are that the patients such as weakness of the spleen and the stomach, insufficiency of vital energy and blood, lassitude, insomnia are fine
Health care product.
Red date tea currently on the market is being simply mixed using jujube and tealeaves mostly, and so, jujube steeped one
It is often tasteless after secondary, the sweet fragrance of jujube can not be experienced after repeatedly brewing again.
Summary of the invention
The present invention provides a kind of manufacture craft of jujube black tea, tea perfume and jujube are aromatic strongly fragrant, and repeatedly brew and still remain with
The sweet fragrance of jujube.
To achieve the above object, the technical solution of the present invention is as follows:
A kind of manufacture craft of jujube black tea, it is characterised in that the following steps are included:
(1) leaf picking, the bud point of plucking fresh tea leaf;
(2) it withers, fresh leaf is spread in withering trough, every square metre of placement 1.8-2.5kg tealeaves, every 2h is turned over once, withered
It withers 8-10 hours;
(3) it rubs, is rubbed using rolling machine or craft, deblocked after the completion of rubbing;
(4) tealeaves is placed in fermenting cellar by one time fermentation, and at 25-28 DEG C, humidity 90-95%, tealeaves is thick for temperature control
Degree is 10-15cm, and one layer of wet gauze of upper cover, fermentation time is 2-3 days;
(5) first drying is baked with dryer, and drying temperature is 40-50 DEG C, drying time 1-2h;
(6) secondary fermentation, after jujube is fumigated 5-7min with steam, treated, and tealeaves is mixed with step (5) rapidly, wet
Heap carries out secondary fermentation, and every 1-2h is turned over once, and fermentation time is 1 day;Jujube and tea screening are come after pile-fermentation;
(7) secondary drying Tumblies Dry, and drying temperature is 40-50 DEG C, and being dried to tealeaves moisture content is 9-12%;
(8) tealeaves is mixed with jujube: in closed air conditioning chamber, tealeaves is alternate by one layer of one layer of jujube of tealeaves with jujube
Tiling, covers one layer of wet gauze on face, and the weight ratio of tealeaves and jujube is 4-5: 1, and temperature control is at 35-45 DEG C, the time
It is 1-2 days;
(9) tealeaves and jujube airing: selection ventilation, clean place, airing tealeaves and jujube, time 5-8h;
(10) it dries three times, tealeaves and jujube is dried together, drying temperature is 40-50 DEG C, and wherein tealeaves contains
Water rate is dried to 5% hereinafter, hand pinches tea stalk into end.
Further, the treatment process of the jujube are as follows: jujube is cleaned with clear water, is drained the water, jujube core is removed, by jujube
It is cut into the bulk of 3-5mm × 3-5mm.
Further, in the step (6), when jujube is mixed with tealeaves, tealeaves is divided into 2-2.5kg a pile, often
Heap tealeaves is mixed with the jujube of 0.5-0.8kg respectively, and pile fermentation carries out secondary fermentation rapidly after turning uniformly.
Further, in the step (8), one piece of wet gauze is replaced immediately after gauze is dry.
A kind of above-described manufacture craft of jujube black tea, the micro-pore of tealeaves absorbs the perfume (or spice) of jujube when production
Gas can also be covered so that the jujube black tea remains the odor characteristic of black tea strong fragrance itself, and the taste fragrant and sweet with unique jujube
Lid black tea per se with astringent taste;Black tea black tea after brewing, millet paste color orange is bright limpid, and fragrance sweetness is mellow, and taste is thick and heavy
Sweetness, tooth cheek lasting, aftertaste strong fragrance after having drunk, repeatedly brews the fragrance for still remaining with black tea itself and jujube, to like tea people
Scholar provides new selection.
