Light is sealed, and control humidity is 85% or so, and timing ventilation is breathed freely.
(7) turning cools：When by 10~15 days pile fermentations, temperature was more than 50 DEG C, and tea sends vinasse sweet fragrance without sentimental taste
When, carry out turning and deblock cooling, will be in the middle of the tea brick tea push-in of top, middle tea is put in side and pushed up, and above-mentioned temperature, occurs again in pile fermentation again
When degree, smell, turning is deblocked, and thin stand carries out air-drying alcoholization, natural air drying 2~3 days, to moisture 15% or so.
(8) screening, which is picked, picks assorted：The semi-finished product that pile fermentation is refined pick and remove thick stalk, old piece, sub-sieve is assorted, point heap
Afterwards,
(9) steam pressure：According to water content of tea is determined, it is determined that claiming tea number, soft 15~20 are steamed in 100~102 DEG C of high steams
Second, enter mould pressing and fixiform while hot.
(10) dry：The compressed tea suppressed is placed on the shelf in drying shed, temperature control is at 35~40 DEG C.
(11) storage ageing (after-ripening)：Carried out with special, constant-humidity constant-temperature regulation and control aging workshop, the temperature of ageing is 25~30
DEG C, ventilation be 10~20m3/h, relative humidity 80%, the time be 5~10 days.Then warehouse entry is deposited in the ground of shady and cool humidity
Side, is aged by the later stage or so half a year.Soup look becomes redder dense, and produces old taste, formed large leaf (post-fermented tea) black tea it is red,
It is dense, alcohol, the characteristics of old.
3.2 in tea making analysis of components method
Water content --- 1 hour rapid test method
Water extraction --- full flow method
Tea Polyphenols --- tartaric acid iron colorimetric method GB8313-87
Soluble sugar --- anthrone colorimetry
Theaflavin, theabrownin, thearubigin --- system analysis method
3.3 organoleptic evaluation method
By the expert for being engaged in tealeaves work and the tea judgement person for testing tea processing factory using tealeaves organoleptic evaluation method (SB/
T10157-1992) evaluated, according to the particularity of post-fermented tea, same sample, which is continuously brewed, to be evaluated three times.Evaluate point dry
Comment and commented with wet, based on soup look, fragrance, flavour, tea residue.
4. interpretation of result
Influence of the 4.1 pile fermentation stage different disposals to post-fermented tea quality
Great Ye tea cakes (post-fermented tea) attributional analysis result after the production trial-production of table 1
Note：Control experiment only with bacterium solution it is different from the present invention.
