Abstract
The present invention provides a kind of preparation method of tealeaves it is characterized in that first by tea-drying, make the content of its water below 5%, then tealeaves is placed in cavity, purity oxygen is passed through in cavity, if tealeaves is loose tea leaf, then processing time of the tealeaves in oxygen-enriched cavity is at least 12 days, if with a thickness of the tea cake or tea grain of 10-25mm, then processing time of the tealeaves in oxygen-enriched cavity is at least 40 days, if then processing time of the tealeaves in oxygen-enriched cavity is at least 70 days with a thickness of the tea cake or brick tea of 30-50mm.Compared with the prior art the present invention, has the advantages that tannin, will not influence tea quality, mass production easy to accomplish can be removed in the short time.
Description
Technical field
The present invention relates to tea processing technical fields, and in particular to a kind of preparation method of tealeaves.
Background technique
Some existing tealeaves (such as Pu'er tea), need to place for a long time (such as 2 years or more), when making tea, tea it is puckery
Taste just disappears substantially, and tea just has lubrication, aromatic mouthfeel.Moreover, the time with placement is longer, the tea taken is bubbled out
Mouthfeel is better, and the value of tealeaves is higher.Trace it to its cause is because tannin rich in, tannin not only influence to be steeped in fresh tea leaf
The taste of tea out makes bubbled out tea have astringent taste, moreover, human body, which excessively takes in tannin, will cause oxygen content in blood of human body
It is low, when serious, human body is made to suffer a shock.The place that tealeaves is placed on aeration-drying is stored for a long time using traditional technique, makes tealeaves
In tannin aoxidized by the oxygen in air, to eliminate the tannin in tealeaves, the shortcomings that such method is that the time is too long, when long
Between storage during be not easy guarantee storage environment condition stabilization, long-time store during be easy because environmental condition change
Change (such as variation of humidity, temperature) to go mouldy, moreover, being not easily accomplished mass production.
Summary of the invention
To solve the deficiencies in the prior art, goal of the invention of the invention is to provide a kind of energy short time interior removing tannin
, the manufacturing method of the tealeaves of mass production that will not influence tea quality, easy to accomplish, the present invention uses following technical side
Case:
A kind of preparation method of tealeaves makes the content of its water 5% hereinafter, tealeaves is then placed in cavity first by tea-drying
It is interior, purity oxygen is passed through in cavity, if tealeaves is loose tea leaf, processing time of the tealeaves in oxygen-enriched cavity is at least 12 days,
If then processing time of the tealeaves in oxygen-enriched cavity is at least 40 days, if thick with a thickness of the tea cake or tea grain of 10-30mm
Degree is the tea cake or brick tea of 30-60mm, then processing time of the tealeaves in oxygen-enriched cavity is at least 70 days.
Preferably, in the preparation method of tealeaves above-mentioned, first tealeaves is put into cavity, then in cavity to tealeaves into
Row heating, drying, drying tea leaves in the process drained by the exhaust gas discharge port of cavity by generated aqueous vapor, is accorded with to water content of tea
When conjunction requires, the gas vent of cavity is closed, and oxygen is passed through by oxygen inlet, and keep the air pressure in cavity in 0.01-
Between 0.40MPa.
Preferably, in the preparation method of tealeaves above-mentioned, the tealeaves is loose tea leaf, processing of the tealeaves in oxygen-enriched cavity
Time is 15-25 days
Preferably, in the preparation method of tealeaves above-mentioned, the tealeaves is the tea cake or tea grain with a thickness of 10-30mm, tealeaves
The processing time in oxygen-enriched cavity is 40-70 days.
Preferably, in the preparation method of tealeaves above-mentioned, the tealeaves is the tea cake or brick tea with a thickness of 30-60mm,
Processing time of the tealeaves in oxygen-enriched cavity is 70-160 days.
Oxidation processes are carried out to tealeaves for convenience, first put tealeaves in cavity into, then tealeaves is carried out in cavity
Heating, drying, drying tea leaves in the process drained by the exhaust gas discharge port of cavity by generated aqueous vapor, is met to water content of tea
It is required that when, the gas vent of cavity is closed, and oxygen is passed through by oxygen inlet.Tealeaves under the action of oxygen, contained by
Tannin is aoxidized by oxygen, since what is be continually fed into is pure oxygen, in this way, just accelerating the speed that tannin is aoxidized by oxygen, is shortened
The time of tealeaves processing, simultaneously as tealeaves is under oxygen-enriched environment, tealeaves has adsorbed a large amount of oxygen, in this way, making tea
When, in tea naturally can oxygen rich in, such tea has good health-care effect to human body.Tealeaves is in water
Content is the processing just carried out under oxygen-enriched environment in 5% situation below, is the tannin in order to avoid tealeaves in oxidation process
It is oxidized into tannic acid.
The beneficial effects of the present invention are: due to using oxygen-enriched environment come storing tea, having can remove in the short time
The advantages of mass production tannin, that will not influence tea quality, easy to accomplish.
