Abstract
The invention discloses a processing and production method of privet-leave tea. The invention is characterized in that the processing and production method comprises the following nine major steps: picking the privet leaves, peeling the privet leaves, airing the enzymes, deactivating the enzymes, air-drying, kneading, screening and classifying, refining the aroma, dehydrating and the like. The processing and production method has the beneficial effects that the leaf stems and the thick leaf veins of the tender privet leaves which are freshly picked are peeled, so that the refreshing and pure taste of the privet-leave tea can be preserved; enzymes in the leaf stems and the thick leaf veins are further deactivated by water vapor, so that the pure aroma of the privet-leave tea can be further ensured; the enzyme deactivation and the air-drying are performed on a conveyer belt so that the shapes of the privet leaves are kept and the strips formed by the privet leaves are uniform in shape; the kneading is performed when the privet leaves are hot, so that the privet leaves can be better shaped and the astringent taste of the privet leaves is removed; and the astringent taste can be further covered by the step of refining the aroma. The privet-leave tea produced according to the processing and production method has the advantages that the privet-leave tea is uniform in appearance, jade-green in color, refreshing and thick in aroma, dark-green and transparent in tea-soup color, tender and mellow in tea-soup taste as well as exquisite and fragrant tea-soup flavor. The processing and production method greatly improves quality of the privet-leave tea product.
Description
Technical field
The present invention relates to Tea Processing manufacture technology field, particularly a kind of processing method of glossy privet leaf tea.
Background technology
Glossy privet tree is evergreen shrubs or arbor, Gao Keda 25m, bark taupe, and branch yellowish-brown, grey or aubergine are cylindrical, dredges raw circular or Long Circle hole skin.Single leaf is to life; The long 1-3cm of petiole, upper mask ditch; Blade keratin, avette, long avette or oval to wide ellipse, long 6-17cm, wide 3-8cm, the sharp point of tip is point or blunt extremely gradually, basal circular, sometimes wide wedge shape or gradually narrow.Panicle top is raw, long 8-20cm, wide 8-25cm; Peduncle reaches 3cm; Inflorescence base portion bract Chang Yuye homotype, squamella lanceolar or linear, withers and falls; Flower is without stalk or near without stalk; Calyx without hair, long 1.5-2mm, tooth is not obvious or closely cut shape; The long 4-5mm of corolla, the long 2-2.5mm of sliver, reflexed; The long 1.5-3mm of filigree, flower pesticide Long Circle, long 1-1.5mm; The long 1.5-2mm of style, column cap is bar-shaped.Fruit kidney shape or nearly kidney shape, long 7-10mm, footpath 4-6mm, deep blue-black is reddish black time ripe, by white powder.The florescence 5-7 month, really May in July phase to next year.
Glossy privet leaf is containing oleanolic acid, to monohydroxy benzyl carbinol, make injection with its fresh leaf and dry sweet wormwood, experiment in vitro shows all have inhibitory action to staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and its active ingredient may be the bond of Syringin, tannic acid and sweet wormwood.Can well absorb after intramuscular injection, without overt toxicity.Cosmosiin, cyanidenon-7-glycoside, and Syringin, ursolic acid.
Glossy privet leaf can removing heat to brighten vision, the loose stasis of blood of removing toxic substances; Detumescence cough-relieving.Main head's dusk pain; Wind-heat cute conjunctivitis; Aphthae; Swelling and aching of gum; Sore turgescence canker, scald; Cough with lung heat.
Therefore, among the people have mode glossy privet leaf being made tea product more, but existing glossy privet leaf tea follows traditional method of kneading that completes, although experienced by a lot of improvement, but still there is many deficiencies, as uneven in completed, fragrance is impure, bar rope winding up is irregular, and tea flavour, with bitterness etc., has had a strong impact on the taste class of product.
Summary of the invention
Technical problem to be solved by this invention is a kind of processing and fabricating method providing glossy privet leaf tea for the problems referred to above, and can solve glossy privet leaf tea fragrance impure, bar rope winding up is irregular, tea flavour with the problem of bitterness, to improve the quality of glossy privet leaf tea product.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is a kind of processing and fabricating method of glossy privet leaf tea, it is characterized in that comprising the steps:
(1) pluck: pluck the normal homogeneity blade of green on glossy privet branch bar, clean by clean water; Described homogeneity blade is old tender consistent blade.
(2) shell leaf: peel off petiole and thick vein for subsequent use, stay and only contain the blade of veinlet.
(3) spread out green grass or young crops: blade is cut into the square vanelets that the length of side is 1-3cm, vanelets is positioned on the blue or green plate rail in stand and spreads 2-3 hour, spread thickness 2-3cm, every 30min stirs once gently.
(4) complete: petiole step 2 peeled off and thick vein are put in boiler to add water and hotted plate, utilize its steam to complete; Put into by vanelets on steam inactivation machine conveyer belt, at the uniform velocity drop into, evenly spread out and pave, lay thickness 1-2cm, vapor (steam) temperature 130-140 DEG C, steam pressure 0.02-0.03Mpa, steam flow is 210-220kg/h, fixation time 90-120s.
(5) wind dries: put on dryer conveyer belt the vanelets after completing with hot-air seasoning immediately, at the uniform velocity, evenly should spread out during input and pave, lay thickness 2-3cm, when putting in storage, hot blast temperature is 85-95 DEG C, when delivering from godown, hot blast temperature is 65-75 DEG C, blast is 0.02-0.03Mpa, and hot air flow is 8000-9000m3/h, and drying time is 20-30 minute.
(6) knead: vanelets is taken advantage of heat to put into kneading machine and kneaded, knead while pressurize after drying by wind, until form the glossy privet leaf bar rope of tight knot;
(7) sieve: remove with mesh screen and knead the impurity be mingled in glossy privet leaf bar rope produced in process.
(8) Titian: with the smokeless charcoal that tea tree limb or tea seed episperm make, Titian is cured to glossy privet leaf bar Suo Jinhang, keep temperature 75-85 DEG C under smokeless state, cure time 10-15 minute.
(9) dewater: dehydrate with dehumidifier at normal temperatures, until the moisture in glossy privet leaf bar rope is less than 8%, namely obtain glossy privet leaf tea.
The invention has the beneficial effects as follows and pluck fresh and tender glossy privet leaf, then peel off petiole and thick vein, the pure pure of glossy privet leaf tea can be kept like this, adopt petiole and thick vein water vapour to carry out steam beating, can ensure that glossy privet leaf tea fragrance is pure further; Carry out on a moving belt completing and wind baking, can blade shape be kept, and the bar rope making it be formed is uniform; Taking advantage of heat to carry out kneading can better moulding the astringent taste removed in glossy privet leaf, can cover astringent taste further after Titian; The glossy privet leaf tea outward appearance of such making is neat, color and luster is dark green, dark green transparent, the fresh and tender alcohol of millet paste flavour of pure abundant, the millet paste color and luster of fragrance and, the elegant perfume (or spice) of millet paste smell is strongly fragrant; Substantially increase glossy privet leaf tea product quality.
