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 the yellow tea tea cake of predetermined shape, 3) the yellow tea tea cake 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: 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 softens handtailor container used, is made up of the inside and outside bucket of centrifugal drier, and the interior bucket of described centrifugal drier also overlaps outward and has outer barrel, for holding tea juice.
the yellow tea tea juice of being discharged by centrifugal drier reclaims, and using, so circulating when making next tea cake; Every day completion of processing, to reclaim Chinese cassia tree loose tea tea juice filter and disinfection by ultraviolet light rear enclosed stored refrigerated, for second day, so circulate; Pure water dilution is added after tea sap concentration is too high; Generally make a collection of tea juice with two thoughtful three weeks, then to discard, make new tea juice.
a yellow tea tea cake prepared by use yellow tea finished product loose tea, adopt above-mentioned process to make, its quality is 0.1-5 kilogram.
above-mentioned use yellow tea finished product loose tea is prepared the process of yellow tea tea cake and makes yellow tea tea cake product, overcome existing steam humidification soften and cause the great disadvantage of yellow tea finished product loose tea deterioration, made yellow tea tea cake 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 3-5 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.
three, above-mentioned the technique softening and dehumidifying of humidification at normal temperatures, avoids the impact of high temperature on yellow tea finished product loose tea quality.
