Description
Technical field
The present invention relates to a kind of tea Processing method, more particularly to a kind of river to wash one's hair No. 28 tea tree breeds and process flat green tea
Method.
Background technology
It is that article kind validation board of farmers' of Sichuan Province in 2010 authorizes the provincial new tea cultivar passed through, choosing that river, which washes one's hair No. 28,
It is the Zhi Chun tea companies of Sichuan one and Sichuan Agricultural University's Tea department to educate unit, and the new varieties of inventor's seed selection.The kind
Belonging to half arbor type, great Ye classes, its bud head is stout and strong, germination is neat, the food value of leaf is soft, holds that tender property is strong, and tender shoots is in yellow green, and fine hair is more,
The slightly fragrance of a flower.The variety yield is high, 667m2(1 mu) about produces 401.0 kilograms of simple bud.Kind spring tip simple bud length, the leaf of a bud one,
Two leaves and a bud length is respectively 2.71cm, 4.30cm, 6.93cm, and hundred-bud weight is respectively 12.38g, 24.41g, 45.15g, and with four
Chuan Cha areas main breed Fuding white tea, good fortune select No. 9 to compare, simple bud length, the leaf of a bud one, the two leaves and a bud length point of Fuding white tea
Not Wei 2.15cm, 3.51cm, 6.01cm, hundred-bud weight is respectively 8.53g, 18.15g, 37.23g, and good fortune selects No. 9 bud-leafs length difference
2.06cm, 3.37cm, 5.78cm, hundred-bud weight are respectively 7.81g, 16.58g, 34.42g, and river washes one's hair No. 28 buds and is all remarkably higher than good fortune again
The big white tea of ancient cooking vessel, good fortune select the Sichuan main breeds such as No. 9, wherein, the hundred-bud weight of only bud selects No. 9 weights than Fuding white tea, good fortune respectively
45.13%th, 58.51%.It can thus be seen that No. 28 stout and strong heavy realities of the more general tea tree breed of bud-leaf, therefore, Yi Caixian are washed one's hair in river
Leaf, particularly easily adopts only bud, and the harvesting general kind of benefit ratio is high by 40%~50%.At present, tea picking labour is nervous, because
This, the kind has good promotion prospect.
The flat green tea of Sichuan production mainly has green bamboo snake, tongue of sparrow etc., and kind used is with middle leaflet kind such as good fortune during making
Select No. nine, Fuding great Bai, Mingshanbaihao etc. is solely based on bud or the just exhibition of the leaf of 1 bud 1.Its reason is the top grade using green bamboo snake as representative
The green young tea leaves of flat require profile it is flat it is straight, neat and well spaced spend, flavour alcohol is felt well, the tender even plumpness of tea residue, and the bud head of large leaf tea tree is more
Stout and strong, it is big to process the degree-of-difficulty factor of flat green tea, working process is improper easily occur fixing it is irregular it is impermeable, color breen is not fresh
Living, fragrance it is low it is light, profile is rough, flavour is bitter and the defects of with sentimental taste.But from the point of view of current flat green tea development trend,
Because labor cost is continuously increased, in harvesting leaflet kind such as good fortune select No. nine, Fuding great Bai, the only bud 1kg such as Mingshanbaihao, it is adopted
Cost is plucked at 100 yuan or so, and river washes one's hair No. 28 because bud head is stout and strong, easily adopts only bud, the cost for plucking only bud be only 50-60 members/
Kg, therefore, tea grower are more willing to plantation river and wash one's hair the stout and strong kinds of bud head such as No. 28 at present, and also gladly purchase river washes one's hair No. 28 solely for tea processing factory
Bud, flat green tea is produced, to reduce production cost.From the point of view of market comsupton feedback, the even green bud of neat flat of stout and strong and bud shape, because
Quality is more excellent, beautiful outline form, more gets consumer reception.It is however, currently used for the stout and strong bud head processing flat green tea of large leaf
Method larger defect be present, process the flat green tea of formation its quality be difficult to it is green with the flat of middle leaflet kind fresh leaf bud head processing
Tea is compared.Meanwhile river washes one's hair 28 because the big bud of bud is strengthened, it is impossible to is mixed processing with other middle leaflet kinds, it is necessary to individually processing.
Therefore the present invention intends washing one's hair raw material of No. 28 improved tea varieties as production flat green tea using river, invents a utilization kind processing
The technology of high-quality flat green tea with make up at present on the market without high-quality stout and strong bud-leaf made flat green tea the defects of.
Chinese patent notification number CN101548700B, the day for announcing 2012 year 02 month 29, entitled one kind are flat famous green

In the manufacture craft of the present invention, wash one's hair No. 28 improved tea varieties using river and produce the straight and upright smooth green profit of profile, soup look is green
Bright, the aloof from politics and material pursuits flowering of fragrance is fragrant, fresh taste, the high-quality flat green tea of tea leaf quality, mainly employs following processing：
(1) pluck：Famous-brand and high-quality flat green tea requires good appearance, neat and well spaced, cleanliness is good, adopts river and washes one's hair the full of No. 28 not hairtail leaves
Only bud, makes that processed finished products profile length is in the same size, and cleanliness is good, situations such as occurring without hairtail leaf, scale；
(2) stand is blue or green：It is that lost moisture reduces moisture content, promotes fresh leaf to chemically react to spread out blue or green main function.Air
Relative humidity determines the evaporation of moisture with steam pressure, and temperature, humidity can influence steam pressure.Humidity is too low, and evaporation is just
It hurry up, be unfavorable for chemical change；When temperature increases, the increase of moisture movement speed, vapour pressure increase, it is easy to vapor from cell membrane glue
Body diffusion into the surface.Spread out blue or green during thermostatic constant wet chamber head, on the one hand control temperature and humidity to slow down moisture and dissipate in appropriate scope
Hair, fresh leaf keep fresh and alive degree in longer time, are on the other hand advantageous to the enzymic catalytic reaction of chemical constituent in fresh leaf, to perfume (or spice)
The formation of gas is favourable；
(3) manage bar：Manage bar is that tea bar is progressively made in order in the presence of external force, managed directly, blade is wrapped along crimping direction
The firmly bud heart, and tea bar moisture heated portion is volatilized, make the flexibility, viscosity and plasticity of tea base best, be easy to mould needs
Profile.Airing is needed between manage bar process, moisture loss is from outward appearance to inner essence, it is once-forming be easily caused it is outer it is dry in it is wet, produce vexed taste
Youngster, airing make moisture transport, be evenly distributed between bud-leaf.River washes one's hair that No. 28 bud heads are stout and strong, and aproll is slow, therefore low temperature in short-term in four times
Manage bar, middle multiple airing, and manage bar temperature step formula is set, and moisture is scattered and disappeared from inside to outside, is prevented moisture is die-offed from causing leaf
Table shrinkage, bud point upwarp, tea bar bent.
(4) milli is taken off to polish：Tea and pot, tea and tea phase mutual friction, tea bar is further flattened, polished, goes young pilose antler in this process
Hair, forms the flat, smooth of flat green tea.Using being polished when cold pot is de- in the least, low temperature is long, on the one hand cold pot, low temperature leaf table are not easy
Upper ash, ensure that into the green profit of tea color, and being polished when on the other hand long slides leaf mass color.
(5) dry：Tealeaves poor thermal conductivity, heat transfer are slow, bud head outer layer is first done if temperature is too high, are formed " duricrust ", harm
Bud head internal moisture is hindered to continue outside diffusive evaporation.The bud head of this " outer dry interior wet ", bud internal condensate vapor, changed
Learning reaction makes fragrance deterioration, and leaf color dries up.In storage, because actual water content is higher, easily produces ageing product and go mouldy.
The too high moisture evaporation that is also also easy to produce of drying temperature is irregular, and bud head external evaporation is fast, continues high temperature drying, is also easy to produce serious perfume (or spice), more
Gao Shihui produces burnt flavour；The too low temperture of leaves of temperature is corresponding also low, and moisture evaporation is slow, and the heat chemistry of unfavorable quality can be produced when serious
Reaction, tea smell is low, not frank.Using lower temperature, intermittently drying, leak water uniformly, parch from inside to outside, second of dry temperature
Degree makes low boiling kindle incense volatilization higher than for the first time on the premise of retaining blowing perfume (or spice).
The present invention compared with prior art the advantages of be：The stout and strong solely bud that the present invention washes one's hair No. 28 tea tree breeds using river makes
Flat green tea, by this technique, solve the problems such as stout and strong solely bud fixing is irregular impermeable, tea-making quality is poor, can produce
The green profit of profile smooth flat, brews that rear tea shoot is upright tall and straight, full, and soup look is green bright, and the aloof from politics and material pursuits flowering of fragrance is fragrant, fresh taste, leaf
Bottom is fresh and alive, soft, even neat, the flat green tea of excellent quality.
