Description

A kind of manufacture craft of red date black tea

Technical field

The present invention relates to black tea and make field, particularly a kind of manufacture craft of red date black tea.

Background technology

Black tea, belongs to full fermented tea, does dark brown pool and brew millet paste be homophony with redness and gain the name because of it.Black tea is rich in the various nutrient elements such as carrotene, vitamin A, calcium, phosphorus, magnesium, potassium, caffeine, isoleucine, leucine, lysine, glutamic acid, alanine, asparatate, the effect such as black tea has preventing decayed tooth, the whole intestines of stomach invigorating are aid digestion, delaying aging, hypoglycemic, hypotensive, reducing blood lipid, anticancer, radioresistance; Black tea or splendid sports drink, if carrying out needing muscle power and the motion (as marathon race) of endurance is front drinks except can relieving summer heat and quenching one's thirst and keep the skin wet, because the caffeine in tea has stimulating effect, the first burn fat supply heat energy of health can be facilitated again and retain liver vinegar, so allow people have more endurance in motion is carried out.

Red date, containing rich in protein, fat, sugared part, carrotene, Cobastab, C, P and phosphorus, calcium, iron etc., has the good reputation of " natural complex ball ", have stronger press down like, anti-allergic effects.Containing CAMP in red date, muscular strength, dispelling fatigue, hemangiectasis, increase myocardial contractive power can be strengthened, improve myocardial nutrition, have good action to prevention and cure of cardiovascular disease.Red date can also qi-restoratives benefit gas, nourishing blood and tranquilization, strengthening the spleen and stomach etc., is the good health products of patient such as weakness of the spleen and the stomach, insufficiency of vital energy and blood, lassitude, insomnia.

Red date tea in the market, be adopt red date to mix with the simple of tealeaves mostly, so, it is often tasteless that red date steeped once, cannot experience the sweet fragrance of red date after repeatedly brewing again.

Summary of the invention

The invention provides a kind of manufacture craft of red date black tea, tea is fragrant and jujube is aromatic strongly fragrant, and repeatedly brews the sweet fragrance still remaining with red date.

For achieving the above object, technical scheme of the present invention is:

A manufacture craft for red date black tea, is characterized in that comprising the following steps:

(1) leaf picking, the bud point of plucking fresh tea leaf;

(2) wither, spread in withering trough by fresh leaf, place 1.8-2.5kg tealeaves for every square metre, every 2h turns over once, and wither 8-10 hour;

(3) knead, adopt kneading machine or knead by hand, deblocking after having kneaded;

(4) one time fermentation, is placed on tealeaves in fermenting cellar, and temperature controls at 25-28 DEG C, and humidity is 90-95%, and tealeaves thickness is 10-15cm, the gauze that upper cover one deck is moistening, and fermentation time is 2-3 days;

(5) first drying, cures with dryer, and baking temperature is 40-50 DEG C, and drying time is 1-2h;

(6) secondary fermentation, after red date steam is fumigated 5-7min, the tealeaves after processing with step (5) rapidly mixes, and wet heap carries out secondary fermentation, and every 1-2h turns over once, and fermentation time is 1 day; After pile-fermentation, red date and tea screening are come;

(7) secondary drying, Tumblies Dry, and baking temperature is 40-50 DEG C, dry to tealeaves moisture content be 9-12%;

(8) tealeaves mixes with red date: in the air conditioning chamber closed, tealeaves and red date are pressed the alternate tiling of one deck tealeaves one deck red date, the gauze that face upper cover last layer is moistening, the weight ratio of tealeaves and red date is 4-5: 1, temperature controls at 35-45 DEG C, and the time is 1-2 days;

(9) tealeaves and red date airing: select to ventilate, clean place, airing tealeaves and red date, the time is 5-8h;

Dry for (10) three times, dried together with red date by tealeaves, baking temperature is 40-50 DEG C, and wherein the moisture content of tealeaves is dried to less than 5%, and hand is pinched tea stalk and become end.

Further, the treatment process of described red date is: cleaned by red date clear water, drain the water, and removes jujube core, red date is cut into the bulk of 3-5mm × 3-5mm.

Further, in described step (6), when red date mixes with tealeaves, tealeaves is divided into 2-2.5kg a pile, often piles tealeaves and mix with the red date of 0.5-0.8kg respectively, turn rapid wet heap evenly and carry out secondary fermentation.

Further, in described step (8), after gauze drying, change one piece of moistening gauze immediately.

Above-described a kind of manufacture craft of red date black tea, during making, the micro-pore of tealeaves absorbs the fragrance of red date, make this red date black tea remain the strong fragrant odor characteristic of black tea itself, again with the taste that the red date of uniqueness is fragrant and sweet, also can cover black tea itself with astringent taste; Black tea black tea after brewing, millet paste color and luster orange is bright limpid, and fragrance sweetness is mellow, the thick and heavy sweetness of taste, and after having drunk, tooth cheek lasting, aftertaste strong fragrance, repeatedly brew the fragrance still remaining with black tea itself and red date, for liking that tea personage provides new selection.
