for achieving the above object, the present invention takes process, comprise: 1) yellow tea finished product loose tea humidification softens, 2) the yellow tea finished product loose tea of humidification having been softened, send into moulding press and be molded into yellow tea little type tea of predetermined shape, 3) yellow tea little the type tea being molded into predetermined shape is dried to moisture content is less than or equal to 6%.
it is characterized in that: the concrete technology that described yellow tea finished product loose tea humidification softens is:
described yellow tea finished product loose tea is immersed in humidification in the tea juice adopting and prepare with the yellow tea of kind under normal temperature in handtailor container to soften, softening time 3-5 minute; The preparation method of tea juice prepared by the yellow tea of described same kind is: at normal temperatures the loose tea of yellow for same kind tea is immersed in pure water 2-3 hour and produces, the mass ratio of tealeaves and pure water is 1:1.5.
remove after unnecessary tea juice divides through centrifugal drier at normal temperatures, obtain humidification soften after yellow tea finished product loose tea.
described yellow tea finished product loose tea humidification is softened handtailor container used, is made up of the inside and outside bucket of centrifugal drier, the interior bucket of described centrifugal drier outward also cover have outer barrel, for holding tea juice.
the yellow tea tea juice that described centrifugal drier is discharged is reclaimed, uses in little the type tea time of making next group, so circulate; Completion of processing, filtered the tea juice reclaimed and refrigerated after disinfection by ultraviolet light, for second day, so circulate every day; Add pure water dilution after tea sap concentration is too high, generally making a collection of tea juice with two thoughtful three weeks, then can discard, makes new tea juice.
yellow tea little type tea prepared by use yellow tea finished product loose tea, adopt above-mentioned process to make, its quality is 6-10 gram.
above-mentioned use yellow tea finished product loose tea is prepared the process of yellow tea little type tea and makes yellow tea little type tea product, overcome existing steam humidification soften and cause the great disadvantage of yellow tea finished product loose tea deterioration, made yellow tea little type tea excellent quality in normal temperature water spray humidification " wet heap " softening process.Be analyzed as follows:
the first, yellow tea finished product loose tea is immersed in the tea juice adopting and prepare with the yellow tea of kind, and tea juice has completely cut off air, creates anaerobic environment, greatly reduces non-enzymatic oxidation.
the second, because yellow tea finished product loose tea is immersed in tea juice, rate of moisture absorption is fast and very even, as long as softening time 5-8 minute, with normal temperature spray water humidification " wet heap " soften compared with the time short, not easily cause the further fermentation of yellow tea finished product loose tea, cause deterioration.
