Abstract

The invention relates to a method for processing high-perfume type Yunnan black tea. The method comprises the following steps: picking up fresh tea leaves respectively having a bud and a leaf, wherein the fresh tea leaves are used as raw materials; uniformly spreading the fresh leaves on a screen mesh; introducing hot wind of 28-30 DEG C into the fresh leaves to deteriorate the fresh leaves for 3-4 hours until the weight-loss ratio of the fresh leaves reaches 38-42 percent; putting kneaded tea germd in a fermentation box and introducing hot wind of 35-40 DEG C for 2.5-3 hours; unbinding the fermented tea germs and putting the unbound tea germs into a multifunctional carding machine to carding mold and carding shape by controlling the temperature to be 85-90 DEG C and the time within 40-50 minutes; and uniformly putting the molded tea germs in a perfume preserving groove and drying the tea germs by steam by controlling the temperature in the perfume preserving groove to be 65-70 DEG C and the perfume preserving and drying time within 3.5-4.5 hours. The method has short processing time and high efficiency and effectively solves the problems of easy volatilization and difficult perfume preservation of aromatic substance contained in the Yunnan black tea. The prepared product has appearance style similar to that of a gold needle and has attractive appearance, exposed gold germs, beautiful germ sharps and complete germ leaves.

Description

The processing method of high-perfume type Yunnan black tea

Technical field:

The present invention relates to tea Processing method, particularly a kind of processing method of high-perfume type Yunnan black tea.

Background technology:

Black tea is one of traditional six big teas of China, and Yunnan black tea tea is the special product in Yunnan, in traditional tea-manufacturing technology of Yunnan black tea tea, does not have that bright leaf is assorted, a plastotype, guarantor's perfume operation.

The manufacture craft of conventional black is generally raw material, the accent that withers, knead, oven dry and finished product.The accent that withers is the critical process that the Yunnan black tea quality forms.At present processing method mainly contains the indoor groove that withers naturally that being in harmonious proportion withers and transfer and adds wind and wither and transfer two kinds, time 16-26 hour (it is long between timing to wither rainy season) of the accent that wherein withers naturally.Wither and transfer groove to wither to be 8-10 hour between timing, quality is lower than nature accents that wither, as the accent leaf that withers is all spent inequality.Traditional general 16-18 hour of fermentation time, the high temperature drying perfumery is volatile.

Summary of the invention:

The objective of the invention is to not high, the bright and beautiful elegant aesthetics of profile of traditional Yunnan black tea tea fragrance, wither that it is long to readjust the distribution the ferment time, the volatile deficiency of aromatic substance provides a kind of processing method of high-perfume type Yunnan black tea; This Yunnan black tea tea process is short process time, and efficient is high, efficiently solves Yunnan black tea tea and includes aromatic substance and volatilize easily; Be difficult to protect fragrant problem, the product shape style of processing likeness in form acupuncture needle, brocade attractive in appearance is elegant; The gold milli appears, and Miao Feng is beautiful, and bud-leaf is complete.

The specific embodiment:

This Yunnan black tea tea process provided by the invention further specifies through following concrete steps:

1, leaf picking: pluck the fresh tea leaf in its of a bud one leaf, kind is a raw material with No. nine, Fengqing, No. three, Fengqing, No. three, clear water and Yunnan colony kind.

2, the assorted accent that withers of bright leaf: utilize the tealeaves adsorptivity strong, wither and transfer the characteristics that have physics, chemical change, improving withers transfers technology, control to wither accent to the product quality influence factor.Bright leaf evenly is spread out on the screen cloth, and thickness 15-20cm adds 28-30 ℃ of hot blast accent that withers fast; Withering between timing is 3-4 hour, and the accent degree of withering GPRS fresh tea becomes dark greenly by bud green, and green grass gas disappears; The blending of withering is revealed, and blade is soft, and toughness strengthens; New tender stem is not easily broken, and bright leaf weight-loss ratio reaches 38-42%, can knead.

3, fermentation: temperature, humidity and time are the fermentation key factors, improve zymotechnique, effectively regulate temperature, humidity, time, promote it to include the composition conversion and reach best.To knead the tea embryo and put into fermenting case, general thickness 20-25cm adds 35-40 ℃ of hot blast, and time 2.5-3.5 hour, to grasp its tea embryo green grass gas and disappear, blue or green fragrance overflows, and is reddish yellow at the bottom of the leaf.

4, plastotype: the fermented tea embryo is separated group, put into multi-functional carding machine and manage the bar plastotype, drop into tea embryo 2-3 kilogram at every turn and manage the bar typing, temperature is controlled at 85-90 ℃, and the time is grasped 40-50 minute.

5, protect perfume: the tea embryo that will pass through plastotype is evenly put into the fragrant groove of guarantor; Thickness 3-4cm utilizes steam to carry out drying, protects that temperature is controlled at 65-70 ℃ in the fragrant groove; Protect the dry time of smoked bean curd at 3.5-4.5 hour; Utilize low temperature control, efficiently solve Yunnan black tea tea and include aromatic substance and volatilize easily, be difficult to protect fragrant problem.

Promptly make the high-perfume type Yunnan black tea product through above-mentioned steps.
