Abstract
The invention relates to a process method for preparing small ball type oolong by using a finished product oolong loose tea and a product. The process method comprises: (1) humidifying and softening the finished product oolong loose tea; (2) feeding the humidified and softened finished product oolong loose tea into a moulding press for mould pressing to preset-shaped small ball type tea; and (3) drying the small ball type tea which is mould-pressed to the preset shape to a predetermined certain moisture content. The process method is characterized in that the specific process of humidifying and softening the finished product oolong loose tea comprises: (1) immersing the finished product oolong loose tea in a tea juice liquid prepared by the oolong to be humidified and softened in a special container; and (2) removing residual tea juice water by using a centrifugal dehydrator to obtain the softened finished product oolong loose tea. The process provided by the invention overcomes a major defect that the quality of tea leaves is deteriorated in an existing steam humidifying and softening process, and the prepared small ball type oolong is excellent in quality.
Description
Technical field
the present invention relates to process and product that a kind of oolong tea finished product loose tea prepares oolong tea little type tea.
Background technology
at present, oolong tea little the type tea adopting oolong tea finished product loose tea to prepare occurs in market.Because it is instant packed, carries and brew, not perishable, be received by the market.But due to technical matters existing defects, quality and the local flavor of oolong tea little type tea are very poor.Have impact on the market of oolong tea little type tea.Adopt oolong tea finished product loose tea to prepare oolong tea little type tea, most important technical elements is exactly oolong tea little the type tea how making to make, and keeps the original local flavor of oolong tea and quality.In existing technique, the technique softening to oolong tea raw tea material humidification is generally: 1) short time steam high-temperature humidifying softens; 2) normal temperature water spray humidification softens.Because normal temperature water spray humidification softening temperature humidity is lower, soften and need the long period, generally want several hours, the later stage can cause " wet heap " effect, and temperature raises.There is higher temperatures under high temperature and oxygen environment or long-time " wet heap " effect and oxygen environment in above technique, causes the non-enzymatic oxidation that tealeaves is serious, cause the further fermentation of tealeaves, change the quality of oolong tea raw tea material.Therefore need tealeaves to be placed in anaerobic environment to carry 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 oolong tea raw tea material and quality.
Summary of the invention
the object of the present invention is to provide a kind of by oolong 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 oolong tea raw tea material and quality, prepare oolong tea oolong tea little type tea with oolong 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, comprise: 1) oolong tea finished product loose tea humidification softens, 2) the oolong tea finished product loose tea of humidification having been softened, send into moulding press and be molded into oolong tea little type tea of predetermined shape, 3) little for the oolong tea being molded into predetermined shape type tea is dried to moisture content is less than or equal to 6%.
it is characterized in that: the concrete technology that described oolong tea finished product loose tea humidification softens is:
described oolong tea finished product loose tea is immersed in humidification in the tea juice adopting and prepare with kind oolong tea under normal temperature in handtailor container to soften, softening time 3-5 minute; The preparation method of tea juice prepared by described same kind oolong tea is: the loose tea of same kind oolong 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 oolong tea finished product loose tea.
described oolong tea finished product loose tea humidification is softened handtailor container used, is made up of the inside and outside bucket of centrifugal drier, the inner core of described centrifugal drier outward also cover have urceolus, for holding tea juice.
the oolong tea juice of being discharged by centrifugal drier reclaims, and uses, so circulate in little the type tea time of next next group oolong tea of making; Completion of processing, filtered the tea juice reclaimed and refrigerated after disinfection by ultraviolet light, for second day, so circulate every day; 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.
oolong tea little type tea prepared by oolong tea finished product loose tea, adopt above-mentioned process to make, its quality is 6-10 gram.
above-mentioned oolong tea finished product loose tea is prepared the process of oolong tea little type tea and makes oolong tea little type tea product, overcome existing steam humidification soften and cause the great disadvantage of oolong tea finished product loose tea deterioration, made oolong tea little type tea excellent quality in normal temperature water spray humidification " wet heap " softening process.Be analyzed as follows:
the first, oolong 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 oolong 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 oolong 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 oolong tea finished product loose tea quality.
four, owing to adopting the high concentration tea juice prepared by same kind oolong tea as humidification bating liquor, oolong tea finished product loose tea active ingredient is not easily separated out, further ensure humidification soften after the quality of oolong tea finished product loose tea.
