Dog bull brain tea is one of Jiangxi preciousness well-known tea, originates in Luoxiao mountain range southern foot offshoot, the Suichuan County township the Tang Hu mountain Gou Gunao, Tea tree is mainly distributed on height above sea level 450m or more.Geographical location locating for dog bull brain mountain has a moderate climate, and abundant rainfall is sunny, It makes a clear distinction between the four seasons, belongs to the gentle area of middle subtropical zone monsoon.17 DEG C of average temperature of the whole year or so, annual frost-free period at 284 days or so, annual Rainfall 1471mm, average sunshine 1720h, the sunshine-duration is shorter, more diffused lights, and day and night temperature is larger.Wherein, dog bull brain mountain Medium-high and lower mountain ditch soil types is mountain yellow soil, yellowish soil, brown earth and numb sand soil.Low mountain, hills cheuch area soil types are red Earth and mountain yellow soil.Soil organic matter content is no less than 1.5%, ph value 5.0~6.5.In addition, this area forestry vegetation bestrewing rate No less than 70%, tea tree planting area is opened up wasteland using hillside and the foot of the hill, is protected when the reclamation of wasteland and is restored by mountain top, hill-side and road Timber stands and economic forest vegetation.

Tea garden management on dog bull brain mountain was divided into juvenile stage and at age, in juvenile stage, mainly includes keeping crop seedling from drought, moves clump It fills a vacancy, tillage and weeding, reasonable top dressing, getting fat is improved the soil, sizing is trimmed, is pinched and is gently adopted and insect pest preventing and controlling.At age, mainly include Tillage and weeding, deep ploughing improve the soil, tea place fertilising, litter and irrigate, rationally pick, prevent and treat pest and disease damage and tea place trimming.

As shown in Figure 1, being the manufacturing flow chart of dog bull brain green tea according to the present invention, wherein the dog bull brain green tea packet Include step:

S1 picks fresh leaf；

S2, water-removing launch fresh leaf, so that fresh leaf when the barrel temperature of roller fixation machine reaches 380 DEG C to 420 DEG C Color is dark green, and blade face tarnishes, and leaf softness, micro- volume, somewhat viscous, slightly elasticity, fragrance appear；

S3 is rubbed, and in water-removing leaves after spreading for cooling gets damp again, rubs pressurization water-removing leaves by light-weight-light mode, so that Tea juice adheres to blade face, lubricious with certain viscosity；

S4 kills two blueness, and when the barrel temperature of roller fixation machine is at 380 DEG C to 420 DEG C, leaf is rubbed in dispensing, so that leaf Color keeps emerald green；

S5 is rubbed again, after killing two leafiness spreadings for cooling resurgence, is increased deblocking number and is rubbed pressurization by light-weight-light mode and kill Leafiness, so that tea juice adheres to blade face, it is lubricious with certain viscosity；

S6, it is dry, the tealeaves after rubbing again is kept the temperature 1 hour between 90 DEG C to 120 DEG C, so that the quick Titian of tealeaves.

Specifically, in step sl, picking fresh leaf is divided into six grades, respectively special product are superfine (specially offered), and tribute is special Grade (tribute), treasure are superfine (treasure), superfine, level-one and irrespective of size, wherein special product superfine picking simple bud before Clear and Bright, tribute are special Grade picking simple bud before grain rains, the picking of treasure superfine are just opened up in the Beginning of summer previous one leaf of bud, and superfine picking is in the Beginning of summer previous one leaf of bud Carry out, level-one and irrespective of size picking in one bud of time in Clear and Bright to the Limit of Heat, two leaf carry out same tenderness to folder leaf, in addition, for any The picking of grade can accomplish that the leaf tenderness of bud-leaf of picking, cleanliness, freshness, evenness are consistent.

In addition, should all avoid picking rainwater leaf when picking the fresh leaf of any grade, not pick dew leaf, do not pick Purple bud-leaf, does not pick disease pest leaf, does not pick the burnt leaf of jelly, does not pick broken leaf, does not pick fish leaf, scale, the fresh leaf of picking without Base of a fruit head.Although different categories, the standard of plucking of different stage is also different, and the quality criteria requirements to fresh leaf are essentially identical 's.It is required that the old tenderness of fresh leaf is consistent, size is identical, equal cleanliness is good, fresh refreshing spends.

More specifically, further comprising step in step sl:

Control leaf quality；

Execute the picking fresh leaf time；And

Handle fresh leaf.

Fresh leaf is to process the raw material of dog bull brain tea, is the material base to form dog bull brain tea quality.Fresh leaf quality is solid It is so closely related with tea tree breed, ecological environmental condition, cultivation management technology, but under the same conditions, fresh leaf quality is very big It is decided by pick in degree.Although fresh leaf natural quality is good, if picked technology is improper or even coarse, excellent dog can not be made in the same old way Bull brain tea.

In control leaf quality step of the invention, leaf quality mainly includes leaf tenderness, uniform degree and freshness.

The leaf tenderness refers to that tenderness refers to fresh leaf tender degree always, is the important evidence of fresh leaf grade scale, is to determine The primary factor of fresh leaf quality.In general, leaf tenderness is good, good at tea quality.In the present invention, bull brain tea is exactly that picking is thin Tender shoots leaf, using made of consummate frying technology.Leaf tenderness standard is measured mainly according to the composition of the normal bud-leaf of fresh leaf Ratio, bud-leaf size, fine hair number, food value of leaf softness, bud-leaf hold tender property, leaf color and include the composite factors such as effective component It is evaluated.Leaf tenderness is good, and normal bud-leaf ratio is big, few to folder leaf ratio, and leaf color is light green, there is fine hair, and the food value of leaf is soft；It is formed It is higher if the ingredient of quality such as water extraction, tea polyphenols, catechin, caffeine, water soluble pectin, aromatic substance content.Fresh leaf Tenderness is poor, and cellulose, sugar, starch equal size are higher, unfavorable to quality.

Certainly, leaf tenderness is restricted by factors such as tea tree breed, the age of tree, ecological condition, season, fretilization management levels.Together The fresh leaf of one tea tree breed, same standard of plucking, the horizontal high and spring tea of between twenty and fifty tea tree, suitable ecological condition, fretilization management Leaf tenderness it is high, it is good to hold tender property.

The fresh leaf is uniform to spend the uniformity coefficient for referring to fresh leaf.Dog bull brain tea requires that fresh leaf is uniform spend, it is old it is tender unanimously, greatly Small consistent, bud-leaf is complete, is not crushed, and is free of non-compliant bud-leaf, is free of old leaf, tea fruit, pest and disease damage leaf, frostbite leaf, fish Leaf, scale and non-tea field trash are processed into form quality and excellent dog bull brain tea with benefit.

The freshness of the fresh leaf refers to the freshness of fresh leaf.Fresh leaf from tea tree adopt it is lower after, respiration is not stopped still , amount of heat is released, the carbohydrate breakdown in fresh leaf is promoted.If the heat generated cannot distribute in time, temperture of leaves will be made to increase, Enzymatic activity enhancing, includes organic substance and further decomposes, and red change occurs for polyphenols oxidation, fresh leaf.If fresh leaf accumulates tension, It is airtight, then in the case where anoxic, fresh leaf is promoted to be converted into anaerobic respiration by aerobic respiration, sugar transition is alcohols, is generated The bored taste of water and alcohol smell, make fresh leaf lose freshness, lose the original physicochemical property of fresh leaf, even result in and rot, lose Process consumption value.

For the plucking time of dog bull brain tea, because of tea tree breed, tea tree growing way, tea area weather conditions, fertile training condition is cultivated And the category of dog bull brain tea and it is different.Plucking time includes mining time and daily plucking time.The northern tea area general productive life is slow, It is exploited in the first tenday period of a month in late April to May；It is exploited in late March to early April in middle part tea area；Southern tea area is opened in mid or late Febuary It adopts.Same tea area is also different due to weather conditions, and winter, early spring was not invaded by cold spell in spring not by freeze injury, and tea shoot sprouts morning, the productive life It can do sth. in advance 1 week or so.The exploitation of early germ kind is early, and in slow bud kind exploitation evening, the white kind germination of such as silver is early, than general local group's productive life 10 days or so ahead of time.Between twenty and fifty tea tree, growth potential be vigorous, the fertile training horizontal good productive life is than old tea tree, the fertile level error, long trained The morning of gesture aging.It is general to determine that the productive life is to grasp to open when tea place has 5% bud-leaf to reach standard of plucking no matter exploitation is early slow It adopts.Some tea areas, the habit adopted if Longjing tea area has and sees bud.

Daily plucking time, each category dog bull brain tea are similar.The precious above quantity of tea is few, and most of is to adopt in the morning Evening frying is adopted in frying in afternoon afternoon, accomplishes to process on the day of the same day adopts.Tea place area is big, quantity is more, then whole day is picked.Such as Artificial or process equipment ability is limited, answers reasonable arrangement to pick and process, accomplishes fresh leaf management work, loses to prevent fresh leaf scarlet Become, influences the quality of dog bull brain tea.

Adopting the control picking fresh leaf time is an important technical for producing dog bull brain tea, is the weight of dog bull brain tea quality Guarantee.Therefore, it is necessary to attach great importance to the plucking time of fresh leaf.It is tender it is fresh, even, only be formulate dog bull brain fresh tea leaves picked technology Main foundation.Each category dog bull brain tea has a whole set of picked technology standard.It is general to require to accomplish not adopt rainwater leaf, do not adopt dew Leaf does not adopt purple bud-leaf, does not adopt disease pest leaf, does not adopt the burnt leaf of jelly, does not adopt broken leaf, do not adopt fish leaf, scale, without base of a fruit head.Picking process Middle requirement, which is gently adopted, puts down gently, frequently adopts and frequently puts, does not pinch tightly, do not compress；Solar radiation is prevented, prevents from stacking and generate heat, prevent mechanical damage； And luck factory inspection is received, and is spread in time, rejects do not meet standard bud and leaves and non-tea field trash in time, it is tender, even, net, fresh to reach bud-leaf.

For the fresh leaf after picking, fresh leaf should be handled in time, in step s 13, fresh leaf is adopted down from tea tree Afterwards, there is no stoppings, respiration still to continue for vital movement.Amount of heat is released in respiration, consumes part dry Matter gently then makes fresh leaf lose fresh refreshing degree if do not taken necessary management measure, heavy then generate the bored taste of water, alcohol smell, the red change of fresh leaf It is rotten, dog bull brain green tea should not be processed, or even lose consumption value.Therefore, fresh leaf processing is a very important job.It is fresh Leaf processing includes fresh leaf examination, transport and processing etc..Fresh leaf examination is to check whether fresh leaf meets the uniform degree of picking, fresh Scale is quasi-.Processing ground is transported to after acceptance(check) in time, can also first transport and check and accept afterwards.Underproof fresh leaf answers otherwise processed, separately It stacks, separately frying.It should accomplish that different cultivars, different tenderness, the fresh leaf in different tea places are separately contained when transport, accomplish with light packs fast Fortune does not squeeze, is not overlapped and stows.The utensil of splendid attire is preferably the bamboo basket basket of perforation, never with cloth bag, polybag and unhygienic There is the utensil of peculiar smell to ship.General every large bamboo or wicker basket is advisable with filling 25-30 kilograms of fresh leaf.

, should be by kind after fresh leaf is transported to processing factory, old tenderness, weather leaf, upper and lower noon leaf, yin, yang slope leaf, blueness strong age and Aged leaf is separately spread.High-grade dog bull brain fresh tea leaves are delicate, should not directly be deposited on cement flooring, should be deposited in soft plaque, winnow with a dustpan On basket and thin bamboo strip pad.Spreading thickness will be suitable for that spring temperature is low, can suitably spread out thickness.Advanced tea booth puts thickness and is generally 3 centimetres of left sides The right side, intermediate dog bull brain tea can spread out 6-9 centimetres thick, fine day, and air themperature is low suitably thick to spread out, excessive to prevent fresh leaf dehydration, influence Frying.The environmental condition requirement spread: relative humidity 90% or so, 15 DEG C of room temperature or so, temperture of leaves control within 30 DEG C.It should spread out In shady place toward the north, direct sunlight is avoided.Most dog bull brain tea are all using spreading as necessary process.Fresh leaf is sent out by spreading Slight oxidation occurs for raw slight physicochemical characteristics variation, tea polyphenols, catechin, and content suitably declines, and reduces the astringent taste at tea, mentions High alcoholic degree.Protein hydrolysis, amino acid content increase.The aromatic substance of part green grass gas is distributed, faint scent sense is increased.With fresh leaf Chemical change, the water content of fresh leaf also changes, and reduces cell turgor, reduces the brittleness of fresh leaf, enhances plasticity, convenient for frying Type is made when processed.Spread the formation that the variation of these physicochemical characteristics of process is conducive to dog bull brain tea shape, matter.Meanwhile may be used also by spreading Effect is improved, cost is reduced, it can energy saving 30% or so.

Spreading the time should not be too long, is generally advisable with 6-12 hours.No longer than 24 hours, especially when room temperature is more than It at 25 DEG C, should not more spread for a long time, accomplish same day fresh leaf as far as possible, same day frying finishes.

The processing of some dog bull brain tea further include pick pick with two processes of sub-sieve, pick that pick be easily except old leaf, freeze injury leaf, pest Leaf, purple leaf, tea fruit and non-tea field trash.Such as dog bull brain special hyson, after fresh leaf is adopted back, it need to strictly be picked and be picked indoors, be picked Except non-compliant old leaf and non-tea field trash.It generally picks and picks 1 kilogram of fresh leaf and need 2-4 hours.Rejecting process is actually also Fresh leaf spreads process, and slight physic-chemical changes also occur, and lays the foundation for dog bull brain tea quality responses.The fresh leaf of advanced dog bull brain Processing includes sub-sieve process.The purpose of sub-sieve is to distinguish bud-leaf size, is convenient for frying, improves quality.Sub-sieve must advance in frying Row, after sub-sieve must frying immediately, damaged to prevent sub-sieve process because of the mutual rubbing surface of bud-leaf, red realization occur as influencing tea Leaf quality.The bamboo sieve of sub-sieve different size carries out, and such as superfine Dragon Well tea fresh tea leaves carry out sub-sieve, sieve using No. 1, No. 3 and No. 4 sieve Fresh leaf afterwards is separately sub, middle to sieve, sieves three, bottom class, carries out frying respectively.Since bud-leaf is of different sizes, water content also not phase Together, a kind of technological parameter is used when frying, necessarily will appear the elastic difference of shape, and smooth flat degree is different, and mass dryness fraction is different, color Swamppink is miscellaneous, or even the drawback more than focus side, red autumnal leaves and powder tea occurs, seriously affects the quality of dog bull brain tea.

Fresh leaf pick pick be dog bull brain tea peculiar process, the fresh leaf after adopting back must further seek unity of standard, pick picking, Remove overproof old leaf, monolithic leaf, to folder leaf, disease pest leaf, Purple tea shoots and non-tea material.It is fresh under being adopted after early morning or rain Leaf is wanted very thin and is spread out, and frying again after the water of surface is dried.

After step S1 and before step S2, further comprise the steps of:

Spread fresh leaf.Spread be dog bull brain tea make before fresh leaf processing (slightly withering) significant process.It is to steam that it, which is acted on, Hair partial moisture makes the food value of leaf become soft, is easy to moulding during frying, simultaneously because moisture evaporates, water-removing pot temperature is stablized, It is easy to control water-removing quality, also saves the energy and artificial；Another aspect fresh leaf, with the evaporation of moisture, generates one after spreading The biochemical reaction of series, tea polyphenols mild oxidation, water extraction and amino acid increase, and chlorophyll is reduced etc..These variations There is improvement for tea color, millet paste flavour, fragrance and tea residue during spreading, it is aobvious to the quality effect for promoting dog bull brain tea It writes.

Fresh leaf into factory should be spread respectively on bamboo mat or clean cement by different kinds, different plucking times On ground, 3-5 centimetres of thickness is spread.Spread the time generally 4-6 hours, should feel like jelly depending on weather condition to the food value of leaf, bud Leaf is unfolded, and issues faint scent, leaf water content is to be appropriateness in 68-70%.

In step s 2, water-removing is the first procedure that green tea is just made, and forms the green critical process of the clear leaf of green tea soup. Main purpose is the activity using high temperature enzyme, prevents the red change of leaf；Moisture in leaf is evaporated, so that the food value of leaf is softened, convenient for rubbing It twists；Green grass gas is distributed, faint scent is volatilized.Must comply with when water-removing: high-temperature fixation, from low to high, old leaf is tender to kill, and tender leaf kills always, Diaphanometer combines, and mostly lacks bored principle thoroughly.Pot temperature generally rests in 380 DEG C -420 DEG C.

In step s 2, it finishes to fresh leaf, it is necessary to follow following 3 principles:

(1) " high-temperature fixation, from low to high ".The leaf tenderness of dog bull brain tea is good, moisture content is more, enzymatic activity is strong, therefore, Want high-temperature fixation.With raising temperture of leaves come the activity of destructive enzyme.In water-removing early period (fresh leaf was cooked in 1-2 minutes), tealeaves is largely inhaled The heat of pot is received, fresh leaf moisture vaporization rate is fast, and the heat of consuming is big, and fixation time is short.It it requires high-temperature fixation It is able to satisfy its thermal requirement, leaf water reduced, should accordingly reduce pot temperature, keep leaf equal with the evaporation of moisture the water-removing later period Even dehydration, the activity of inactive enzyme prevent tealeaves coke from becoming.

(2) " tremble bored combination, tremble less bored " more.This is the effective measures for improving dog bull brain tea water-removing quality.During water-removing Tremble bored combination, it is necessary to flexibly grasped according to the quality of fresh leaf, the vapor after making full use of leaf water to vaporize improves leaf Temperature, is conducive to kill even, and red stalk red autumnal leaves out, do not cross linear leaf and steamed when bored, it may appear that yellow maturity phenomenon, fragrance is low light, influences Tea quality.Whole process trembles stir-fry, and moisture and the volatilization of green grass gas are fast, and Destruction of Chlorophyll is few, advantageous to tea leaf quality, still, normal easy shape It is irregular at water-removing degree.Temperture of leaves are not high, are also easy to produce red stalk red autumnal leaves and dehydration is irregular.From the point of view of most of dog bull brain tea, with " more Tremble less bored " fixing method preferably.Also there are a small number of dog bull brain tea requirement " how bored to tremble less " or " trembling bored combination ".In water-removing process In make full use of tremble with bored effect, reasonably adjust control blade variation, can be only achieved the optimum efficiency of water-removing.

(3) tender leaf kills always, and old leaf is tender to kill ".The fresh leaf of general dog bull brain tea belongs to tenderer fresh in addition to a small number of teas Leaf.The personnel of related fields should be appreciated that in contrast the old leaf and the tender leaf are.Tender leaf moisture content is high, enzymatic activity By force, cellulose is few, and water-removing degree is preferably suitably laid particular stress on；The tenderness of old leaf is relatively poor, and moisture content is low, suitably tender should kill, keep leaf Face is wet, is conducive to moulding.Because dog bull brain tea water-removing stage and moulding, drying stage have close relationship, water-removing Old tender degree, should flexibly grasp according to the variation of the quality of fresh leaf, dehydration degree and the food value of leaf, leaf elephant.

More specifically, it is finished with green-keeping machine to fresh leaf, tea pot should be polished before water-removing, do the wash clean, upper a little system Tea oil keeps tea pot smooth, and fresh leaf is avoided to glue pot, guarantees water-removing quality.Reach pot temperature in the barrel temperature of green-keeping machine and reaches 380 At DEG C -420 DEG C, fresh leaf is cooked.It after throwing leaf, is adjusted according to water-removing leaves appropriateness degree and throws leaf amount, controlled with the height of leaf-leveling machine. During water-removing, leaf quality should be gone out check at any time, the degree that such as finishes is partially tender, should lower leaf-leveling machine, reduces and throws leaf amount；Such as water-removing Degree is partially old, then increases leaf-leveling machine, throws leaf amount to increase.To master feeding capacity and water-removing degree when dark brownish green using green-keeping machine, really Guarantor kills, kills even, kill-acquaintance.The outstanding feature of the appropriateness of water-removing fresh leaf is: leaf color is dark green, and blade face tarnishes, and the food value of leaf is soft, withers Volume, the bending of folding stalk and it is continuous, tightly pinch leaf can agglomerating, somewhat viscous, slightly elasticity, fragrance appears.

In the present invention, the green-keeping machine is roller fixation machine.

In step s3, water-removing leaves camera lens is rubbed after spreading for cooling, rubs and is carried out on rolling machine.It rubs and throws leaf amount Depending on type size, the food value of leaf always tender situation, actually it is suitable for hand compression.Pressurization is rubbed using light-weight-light mode.It rubs Time and pressurization are closely related, shorten time of kneading and aggravate pressure, easily make to obstruct leaf separation, first broken not at item, have rubbed leaf both Certain cell-damaging rate is not achieved, and is not easy to keep bar rope complete.It rubs the high fresh leaf of grade, is gently pressed being not pressurized or adding Under the premise of, the time must assure that, should not be too short, this is to accomplish to rub appropriateness, not broken, existing item, and protects the important skill of milli point Art measure must then aggravate pressure, the requirement for rubbing leaf is otherwise just not achieved on the contrary, rubbing compared with old leaf.

It after rubbing, agglomerates in order to prevent, needs to deblock to the leaf of rubbing after rubbing, wherein going out in rolling machine It is not pressurized sky before leaf to rub 3-5 minutes, to play the role of deblocking.It rubs under leaf after machine, carries out deblocking drying immediately, be sure not long It sets, in case leaf color turns yellow.Particularly, for the insufficient leaf of finishing, be dried immediately with higher temperature after mixing, prevent after It is continuous to redden

In the present invention, rub appropriate leaf, it is desirable that tender leaf rolled twig rate up to 80%~90% or more, rudimentary thick old leaf at Item rate is 60% or more.For cell-damaging rate between 45%~65%, tea juice adheres to blade face, and hand touches with lubricious viscous feel and feels.

In step s 4, to the secondary water-removing of leaf progress is rubbed, two blueness are referred to as killed.In the step of the invention, step S4 It is identical with the mode of operation of step S2, but the temperature operated is different.Specifically, when killing two blueness, the cylinder temperature of green-keeping machine Degree needs to be advisable at 250 DEG C~280 DEG C.It is required that " high temperature, quick, a small amount of, hydrofuge ", to keep leaf color jade green, out after leaf in time Spreading for cooling.

In step s 5, it is rubbed again to killing two green leaves, in the step of the invention, step S3 and step S5's Mode of operation is identical, but leaf when due to rubbing again is easily agglomerating, in order to avoid leaf agglomeration, it is necessary to increase deblocking number.

In step s 6, the tea spreading after rubbing again is put in the Sheng leaf dish of drying fragrance extracting machine, it is desirable that uniformly spread, thickness Suitably, it is adjusted by technique requirement.Be put into tealeaves, shut chamber door, restart blower, after open heating, heater switch, temperature control exists 90 DEG C~120 DEG C or so keep the temperature 1 hour, so that aromatic substance inside tealeaves is diffused into leaf surface layer, reach the mesh of the quick Titian of tealeaves 's.Water content of tea after drying is not more than 6 percent, and hand pinches tea item into powder, and dry tealeaves is store in time after wanting spreading for cooling enough It deposits.

It is worth one to say, in the present invention, further comprises the steps of:
