Abstract
The invention discloses a three-dimensional multi-layer frame-type numerical-control fermentation method for Pu-erh tea. The three-dimensional multi-layer frame-type numerical-control fermentation method for Pu-erh tea comprises the following steps: (1) carrying out moistening by water; (2) carrying out material-feeding; (3) carrying out a first fermentation; (4) supplementing water before a second fermentation; (5) carrying out the second fermentation; (6) supplementing water before a third fermentation; (7) carrying out the third fermentation; (8) breaking the fermented Pu-erh tea into blocks; and (9) carrying out a fourth fermentation. The fermentation method ensures continuity and fermentation qualities of tea leaf fermentation and shortens fermentation time, so that the fermentation method prevents moisture in the pile from rapidly volatilizing so as to ensure a wet and hot environment for tea leaf fermentation. The Pu-erh tea prepared by the technology is basically free of pile flavor, and has characteristics of aged Pu-erh tea; the Pu-erh tea is red, heavy and bright in soup color, mellow in flavor and sweet in aftertaste; and the Pu-erh tea can be directly drunk and sold.
Description
Technical field
The present invention relates to Tea Processing technical field, in particular to a kind of Folium camelliae assamicae stereoscopic multi-layer frame numerical control fermentation process.
Background technology
The fermentation of Folium camelliae assamicae continues up traditional production method, this fermentation mode is primarily present following shortcoming: 1, depend on natural climate unduly, humiture difference due to Various Seasonal, different weather, even if using identical raw material and technique all cannot ferment the Folium camelliae assamicae (processed) of same quality during fermentation, the unstability of the Folium camelliae assamicae (processed) quality of its production, hinders Pu-Erh Tea industryization development；2, conventional Pu'er tea fermentation is fermented on ground, and sanitary condition is poor, it is difficult to ensure the hygienic requirements of food processing；3, conventional Pu'er tea fermentation heap height only 70cm, floor space is bigger；4, fermentation period is long, it is generally required to about 45 days；4, heap taste is heavier, and it is not good to drink mouthfeel at once, need to display to can be only achieved for more than 3 years and drink requirement, and just can come into the market sale, and capital turnover one is taken turns and is also accomplished by more than 3 years time, and the capital turnover pressure of enterprise is bigger.
For solving the problems referred to above, the Chinese invention patent that publication number is 103355441A discloses a kind of Novel automation type Puer tea fermentation technology, comprises the following steps: (1), Folium Camelliae sinensis humidify；(2), once wet heap；(3), a turning is deblocked；(4), the wet heap of secondary；(5), secondary turning is deblocked；(6), three wet heaps；(7), three turnings are deblocked；(8), four wet heaps；(9), four turnings are deblocked；(10), five wet heaps；(11), five turnings are deblocked；(12) stand, it is delivered under natural environment dry.Folium Camelliae sinensis is only humidified by this fermentation technology in step (1), and the fermentation temperature of the wet heap of secondary is promoted to 55 DEG C by 40 DEG C, and in wet heap Folium Camelliae sinensis, moisture evaporation is too fast, it is impossible to ensure the hygrothermal environment needed for tea leaf fermentation.For this, good environment is created in the fermentation that this fermentation technology cannot be Folium Camelliae sinensis, it is difficult to ensures the continuity of tea leaf fermentation, is difficult to obtain the fermentation of pu'er tea of high-quality in actual production process.
Summary of the invention
The present invention provides a kind of Folium camelliae assamicae stereoscopic multi-layer frame numerical control fermentation process, and to solve existing fermentation technology of Puer tea, to there is moisture evaporation in wet heap Folium Camelliae sinensis too fast, it is impossible to ensures the hygrothermal environment needed for tea leaf fermentation, it is difficult to ensure the defect such as continuity of tea leaf fermentation.
The present invention adopts the following technical scheme that
A kind of Folium camelliae assamicae stereoscopic multi-layer frame numerical control fermentation process, comprises the following steps:

(4) moisturizing before ferment in second time: after one time fermentation terminates, pours out tea raw material from plastic crate, Homogeneous phase mixing after deblocking, adding water and be uniformly sprayed onto on tea raw material, rate of water make-up is the 30% of the former net weight of tea raw material, and making tea feed moisture content is 40 ± 2%, again tea raw material is filled basket to shelve, send into numerical control fermenting house；
(5) ferment in second time: regulating numerical control fermenting house data, make temperature be risen to 48 DEG C gradually by 40 DEG C, humidity is 80%, and oxygen supply is 36s/1h, and row's carbon is 72s/1h, and the ferment in second time time is 10d, and when this ferment in second time terminates, tea feed moisture content is 16 ± 2%；
Moisturizing before (6) three fermentations: after ferment in second time terminates, tea raw material is poured out from plastic crate, Homogeneous phase mixing after deblocking, adding water and be uniformly sprayed onto on tea raw material, rate of water make-up is the 30% of the former net weight of tea raw material, and making tea feed moisture content is 35 ± 2%, again tea raw material is filled basket to shelve, send into numerical control fermenting house；
(7) three fermentations: regulating numerical control fermenting house data, make temperature be risen to 50 DEG C gradually by 48 DEG C, humidity is 80%, and oxygen supply is 36s/1h, and row's carbon is 72s/1h, and three fermentation times are 5d, and when this ferment in second time terminates, tea feed moisture content is 25 ± 2%；
(8) deblocking: the phase III terminates, poured out by tea raw material from basket, after deblocking, Homogeneous phase mixing dress basket is shelved, and sends into numerical control fermenting house；
(9) four fermentations: regulating numerical control fermenting house data, keep the temperature at 50 DEG C, humidity is 0%, and oxygen supply is 36s/1h, and row's carbon is 72s/1h, and four fermentation times are 3d, pack warehouse-in, fermentation ends after playing heap Homogeneous phase mixing.
Further, the water consumption of above-mentioned steps (1) tidewater is the 50% of solar dried green tea raw material net weight.
Further, above-mentioned wheeled fermenting frame at least includes four layers, at least puts four described plastic crates for every layer.
By the above-mentioned description of this invention it can be seen that compared to the prior art, present invention have the advantage that
