Description
Technical field
The present invention relates to tea cake of white tea manufacture technology fields, and in particular to a kind of Fuding white tea low temperature process holding tealeaves is living
The tea cake production method of property.
Background technique
Fuding white tea is not fried and is not rubbed, is that most natural way thinly spreads the fresh tea leaf under adopting and sets on bamboo mat
Under sunlight, or it is placed in the good interior of ventilation and penetrating light effect, it is allowed to wither, dry naturally, since manufacturing process is simple, with
Least process is processed.Therefore, white tea largely remains the nutritional ingredient in tealeaves, and shape bud milli is complete
Whole, soup look is apricot yellow limpid, the quality characteristic that flavour is light, sweetness is tasty and refreshing.According to the difference of picking bud-leaf, white tea can be divided into: white
Milli acupuncture needle, white peony, Shou Mei, new process white tea etc..The free-radical contents of white tea are minimum, flavones content highest, amino acid content
It is higher that average value is higher than the nutrition contents such as flavones, theanine, the organized enzyme of other teas Fuding white teas.
Human body lactones enzymatic activity can be improved in organized enzyme, promotes catabolism of fat, sugar extra in blood in decomposer
Point, promote blood glucose balance.Theanine has the effects that strengthen immunity, protect liver, blood pressure lowering, refreshes oneself, eliminates fatigue.Flavones has
The effect of anti-oxidant, antibacterial, strengthen immunity.
In recent years, it according to market needs, transports for convenience, uses for reference Pu'er tea tea cake, dark green tea brick tea, release again in the market
Press white tea cake etc., but press the manufacture craft that white tea cake has been all made of black tea, Pu'er tea cake at present, high temperature is carried out to white tea
Decatize, fermentation, addition tea juice constant power, make tea cake of white tea, but during high temperature steaming, high temperature can destroy white tea itself
Organized enzyme causes the loss of the relatively multiple nutritive components in tealeaves, loses the original smell of white tea and nutritional ingredient, obtains and do not repay
It loses.
Summary of the invention
To overcome the deficiency, the purpose of the present invention is to provide a kind of Fuding white tea low temperature process to keep tealeaves active
Tea cake production method.
The technical solution adopted by the present invention to solve the technical problems is: a kind of Fuding white tea low temperature process holding tealeaves is living
The tea cake production method of property, comprising the following steps:
D1 receipts blueness: being put into shady and cool ground for the tealeaves of fresh picking, prevents exposure dehydration and fever, and receipts blueness should be used ventilative
Bamboo basket or large bamboo or wicker basket, forbid with the sealing containers such as woven bag, polybag, prevent from squeezing and generate mechanical damage and poor aeration and red
Become；
D2 withers: fresh tea leaf being taken in room of withering and is withered, fresh leaf is uniformly spread on bamboo curtain splint or bamboo sieve, is set
It withers at air circulation, cool place drying, withering time 8-10h, dehydration to water content of tea to 60-70%；
D3 solarization: by the tealeaves after withering, being placed on bamboo curtain splint or bamboo sieve and pave, and puts to shine to water content in the sun and is lower than
8.5%, obtain raw tea material；
The softening of D4 low-temperature humidifying: raw tea material is placed in bamboo curtain splint or bamboo sieve, leaf-spreading thickness 10-15cm is put into close
In the forbay closed, spray nozzle is uniformly provided at the top of forbay, spray nozzle is connected with high pressure low temperature humidification system, to raw material
Tea upper surface sprays high-pressure water vapor, keeps 30-50min, softens raw tea material, obtains softening raw tea material, the low-temperature humidifying system
System is selected from high-pressure spray humidification system or ultrasonic humidifier；
D5 pressing mold: the raw tea material of softening is put into moulding press, the tea cake of 100g, 1 ton of pressure, is kept 1min, is pressed into pre-
The tea cake of white tea of setting shape；
D6 low temperature drying: tea cake of white tea is spread on bamboo curtain splint or bamboo sieve, 35-40 DEG C of hot-air, low temperature drying are passed through
48-72h is dried to foot and does, finished product is made.
Specifically, further include that storage is green: fresh leaf is into after factory, when cannot process in time, it should be put into the green room of storage or refrigeration is protected
Fresh library, leaf-spreading thickness 15-20cm spread out 20 ± 2kg/m of leaf amount2, an air drain is opened every 1 ± 0.1m, storage young worker is carried out and makees,
It wherein stores green room to face north, air circulation, avoids direct sunlight, room temperature control is at 25 DEG C hereinafter, relative humidity is kept
90% or more, the storage green time is no more than 16h and is turned once with keeping the quality of fresh leaf every 2-3h, prevents deterioration, refrigerates
Fresh-keeping warehouse controls fresh leaf temperature at 5 ± 1 DEG C, can keep 3d.
The invention has the following advantages: keeping white tea soft using cryogenic high pressure humidification using most natural manufacture craft
Change, cake of press, while facilitating storage to transport, guarantees the activity and nutritive value of white tea itself.
