Summary of the invention
the object of the present invention is to provide a kind of by white tea finished product loose tea at normal temperatures, the short time is placed in anaerobic environment and carries out short time humidification and soften, to reduce the various biochemical reactions that tealeaves in humidification softening process occurs, that maintain the distinctive local flavor of white tea raw tea material and quality, prepare white tea compressed tea with white tea finished product loose tea process and product.In fact, the object softening to finished product loose tea humidification, to ensure that tealeaves is not broken in pressing process, when pressing pressure is enough large, finished product loose tea soften after moisture content need not be so large, as long as when the softening degree of its humidification reaches compacting, finished product loose tea is not broken, thus the humidification softening process of finished product loose tea is significantly improved space.Therefore, tealeaves is placed in anaerobic environment and carries out short time humidification and soften, to reduce the various biochemical reactions that in humidification softening process, tealeaves occurs, maintain the distinctive local flavor of raw tea material and quality, technique can reach.Its technological means has three critical aspects: one is humidification when softening, and how to soften with the humidification that the technique of easy reality realizes under anaerobic environment; Two is to soften by humidification at normal temperatures; Three is under how allowing finished product loose tea be placed in high humidity environment, and just can realize at short notice softening.
for achieving the above object, the present invention takes process, comprising: 1) white tea finished product loose tea humidification softens, 2) the white tea finished product loose tea of having been softened by humidification, is pressed into white tea compressed tea, 3) white tea compressed tea is dried to moisture content is less than or equal to 6%.
it is characterized in that: the concrete technology that described white tea finished product loose tea humidification softens is:
described white tea finished product loose tea is immersed in humidification in the tea juice adopting and prepare with the white 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 white tea of described same kind is: the loose tea of white for same kind tea is immersed in pure water 2-3 hour and produces, and 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 white tea finished product loose tea.
described white tea finished product loose tea humidification softens container used, is made up of the inside and outside bucket of centrifugal drier, and the inner core of described centrifugal drier also overlaps outward and has urceolus, for holding tea juice.
the white tea tea juice that described centrifugal drier is discharged is reclaimed, using when making next compressed tea, so circulating; 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.
a white tea compressed tea prepared by use white tea finished product loose tea, adopt above-mentioned process to make, its quality is 6-15 kilogram.
above-mentioned use white tea finished product loose tea is prepared the process of white tea compressed tea and makes white tea compressed tea product, overcome existing steam humidification soften and cause the great disadvantage of white tea finished product loose tea deterioration, made white tea compressed tea excellent quality in normal temperature water spray humidification " wet heap " softening process.Be analyzed as follows:
the first, in vain tea finished product loose tea is immersed in the tea juice adopting and prepare with kind oolong tea, and tea juice has completely cut off air, creates anaerobic environment, greatly reduces non-enzymatic oxidation.
the second, because white tea finished product loose tea is immersed in tea juice, rate of moisture absorption is fast and very even, as long as softening time 10-20 minute, with normal temperature spray water humidification " wet heap " soften compared with the time short, not easily cause the further fermentation of white 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 dialogue tea finished product loose tea quality.
four, owing to adopting the high concentration tea juice prepared by the white tea of same kind as humidification bating liquor, white tea finished product loose tea active ingredient is not easily separated out, further ensure humidification soften after the quality of white tea finished product loose tea.
