Abstract

The invention discloses a kind of method using black tea raw material processing dark green tea, its technical solution is as follows: fresh leaf → withering → rubs → ferments → dry (red gross tea) → tidewater (water content 25%) → pile fermentation (temperature 45 C ± 2 DEG C, humidity 80% -90%, 15-20d) → nature airing → decatize → (compacting) of just dry → foot → cool set ageing.The research of this project, it is to jump out traditional six big teas processing technics models to carry out the innovation of processing technology using black tea " fermentation " and dark green tea " pile fermentation " mechanism and feature, black tea processing technology and dark green tea processing technology are organically combined, new process, the new product of dark green tea are formulated out.It is Raw material processing dark green tea using black tea, quality meets or exceeds traditional black tea quality requirement, and reduces water-removing, the pile fermentation time for shortening dark green tea processing and process-cycle, reduces production cost, dark green tea industry overall efficiency can be improved.

Description

A method of dark green tea is processed using black tea raw material

Technical field

The present invention relates to tealeaves production method, in particular to a kind of method using black tea raw material processing dark green tea.

Background technique

Traditional dark green tea processing technology is: fresh leaf, and → water-removing →, which is just rubbed, → heap is bored → rubs again → dries → it choosing point, selection by winnowing, picks Ageing → finished product is set in stalk → assorted → pile fermentation → decatize → drying → cool.Critical process is " pile fermentation " in dark green tea processing technology, is led to It crosses " pile fermentation " raw tea material internal substance and series variation occurs, if tea polyphenols are in conversion wet, under heat condition；In residual activity enzyme Effect is lower to carry out enzymatic oxidation；The differentiation etc. of anaerobe effect under the environmental condition of anoxic, tea polyphenols (it is wet, hot, The effects of residual activity enzyme, anaerobe) → theaflavin → thearubigin → theabrownin, by " pile fermentation " formation " it is red, dense, old, The unique black tea quality style of alcohol ".

Conventional red tea processing technology, which is: fresh leaf → withering → rubs → ferments → just do → spreading for cooling → drying → finished product. Critical process is " fermentation " in black tea processing technology, and series variation, such as tea polyphenols occur by " fermentation " raw tea material internal substance Under the action of polyphenol oxidase: tea polyphenols (polyphenol oxidase enzyme effect) → theaflavin → thearubigin → theabrownin.Utilize technique Technological means improves theaflavin, congo red cellulose content as far as possible, controls dark brown cellulose content, forms " red soup, red autumnal leaves " unique black tea Wool fabric lays the foundation.

The present invention is to jump out traditional six big teas processing technics models, using black tea " fermentation " and dark green tea " pile fermentation " mechanism with Feature carries out the innovation of processing technology, and black tea processing technology and dark green tea processing technology are organically combined, the new work of dark green tea is formulated out Skill, new product provide a kind of new consumption choice for tea market.

Summary of the invention

The present invention has overcome the deficiencies of the prior art and provide a kind of method using black tea raw material processing dark green tea.

Technical scheme is as follows: fresh leaf → withering → rubs → ferments → dry (red the gross tea) → tidewater of just dry → foot (water content 25%) → pile fermentation (temperature 45 C ± 2 DEG C, humidity 80% -90%, 15-20d) → nature airing → decatize → (pressure System) → cool set ageing.

Preferably, it is that nature withers tune in the step (2), wither after fine day 4:30 in afternoon and mediate reason, when processing Between be 2 hours.

Preferably, it is rubbed in two steps in the step (3), just rubbing the time is 10~15 minutes, and rubbing the time again is 6~8 points Clock.

Preferably, fermenting cellar is controlling fermentation room in the step (4), and fermentation temperature is 22-30 DEG C, humidity 80- 90%, when fermentation, is 3-5 days a length of.

Preferably, in the step (8), 70~90 centimetres of pile fermentation tealeaves height, 90~100 centimetres of width, heap temperature control system At 45 DEG C, humidity 80-90%, pile fermentation time 15-20 days.

Preferably, room temperature is 25 DEG C when naturally dry in the step (9), and humidity 75% or so spreads thickness 5-7cm out.

Compared with prior art, the beneficial effects of the present invention are: making black teas using the method for the present invention, tradition is had both The special favor and health-care efficacy of famous-brand and high-quality black tea and dark green tea provide a kind of novel fermentation type health protection tea for market, while advantageous Agriculture increasing both production and income is grown tea in middle leaflet.

Specific embodiment

Present invention is further described in detail combined with specific embodiments below:

1. leaf picking: the raw materials used middle leaflet for summer and autumn picking grows tea tree fresh leaf, a bud or one leaf of a bud or one Two leaf of bud；

2. withering: wither tune naturally；Wither after fine day 4:30 in afternoon and mediate reason, the processing time is 2 hours；

3. rubbing: being rubbed using rolling machine；It rubs in two steps, just rubbing the time is 10~15 minutes, and rubbing the time again is 6~8 minutes.

4. fermentation: being fermented using fermenting cellar, fermenting cellar is controlling fermentation room, and fermentation temperature is 22-30 DEG C, humidity 80- 90%, when fermentation, is 3-5 days a length of.

5. just dry: carrying out preliminarily dried in 30-45 DEG C of drying room of temperature；

6. foot is dry (red gross tea): in 80-105 DEG C of drying room of temperature, being dried within continuous drying 16 hours

7. tidewater (water content 25%): water is typically chosen in afternoon before compacting or carries out at night, tidewater ratio 25% or so, The few tide of top grade material, low grade material is mostly damp, mainly takes nebulizing spray, turns while sprinkling water, is then allowed to stand 9 hours or more, with Moisture, tealeaves softening are absorbed to tealeaves.

8. pile fermentation (temperature 45 C ± 2 DEG C, humidity 80% -90%, 15-20d): the tea that tidewater is crossed is stacked into 70-90 It sprinkles water after centimetre, above covers burlap, promote the zymosthenic progress of tealeaves, be allowed to ferment 20-24 hours or so under hyther

9. natural airing: the tea spreading after pile fermentation is got well drives the processing of row naturally dry into, and room temperature is 25 DEG C when naturally dry, humidity 75% or so, spread thickness 5-7cm out.

10. decatize: with special decatizing apparatus decatize 2-4 hours,

11. compacting: it is suppressed with special press device,

12. cool set ageing.
