Description

A kind of preparation method of wild sweet tea black tea
Technical field
The invention belongs to tea-manufacturing technology technical field, is related to a kind of preparation method of wild sweet tea black tea.
Background technology
Black tea is a kind of full fermentation tea, is the Main Tea product among tea culture.Black tea include souchong, congou tea and Broken black tea, quality characteristic are red soup red autumnal leaves, and profile bar rope tight knot is even straight, and color and luster Wu Run, fragrant aroma, flavour is sweet and pure, has shape Matter and excellent qualitative characteristics.The preparation technology of black tea directly affects its quality.The preparation technology of existing black tea, standard of plucking, is rubbed Twist with the fingers and fermentation procedure has a great influence to sample tea, committed step prepared by category black tea.Existing process of kneading mainly uses kneading machine Commonly kneaded, time of kneading general control in 30min or so, can heavy damage tealeaves surface texture, and by tea juice one And rub out, it is unfavorable for follow-up fermentation procedure, the quality of black tea can be directly affected.
As the patent No. (201410851630.X) discloses a kind of preparation method of black tea, pressure method is kneaded by special And airing zymotechnique, the special method of kneading is to be kneaded with tea twisting machine using the pressurization method of kneading of " light-weight-light " 2 90min, it the overlong time that single is kneaded, causes to knead the vexed Huang of leaf because the program is excessive to the dress leaf amount of tealeaves, system Standby black tea quality is poor, and tea perfume gas is slightly light, and soup look is red to owe bright, and mouthfeel is more bitter, and root of Ford Metalleaf is dark.
The content of the invention
To solve the insufficient problem in current tea rolling technology, the present invention provides a kind of preparation side of wild sweet tea black tea Method, the destruction kneaded in technology to tealeaves surface can be reduced, so as to effectively lift black tea quality.
It is achieved particular by following technical scheme:
A kind of preparation method of wild sweet tea black tea, comprises the following steps:
(1) pluck:Using Wild sweet tea as fresh leaf, the Ching Ming Festival front and rear harvesting one bud one leaf, two leaves and a bud, and choose;
(2) sun withering:The fresh leaf of selection in step (1) is uniformly spread on bamboo hedge, per 2~5kg of hedge, 16:00~17: 00, place sun withering in the sun;
(3) wither:The blade that step (2) is handled through sun withering, spread under low temperature, until blade withers, blade face color becomes Deep, blade softens;
(4) knead:Using tea twisting machine, kneaded, time of kneading 60min, kneaded using pressurization kneading in technique Until tea juice no longer flows out and sends delicate fragrance, tea rolling percentage of damage is 70~85%;
(5) ferment:The tealeaves kneaded is put into fermenting cellar and fermented, fermentation time is 6~8 hours, and blade is changed into deep Ferment and complete during brown;
(6) dry:The tealeaves fermented is put into heating chamber to be dried, dried at twice, first drying temperature is 65 DEG C~75 DEG C, the time, secondary drying temperature was 35 DEG C~45 DEG C at 1~3 hour, 3~5 hours time;
(7) finished product packing:Dried tealeaves, reject impurity, packaging, you can.
It is preferred that low temperature control is uniformly spread in bamboo mat at 24 DEG C~30 DEG C with 1.5-2.5cm thickness in the step (3) On, dry in the air to water content 53%-60%.
It is preferred that in the step (4), tea twisting machine is that rotating speed is 60 turns/min per barreled 8~15kg of tealeaves.
It is preferred that the pressurization in the step (4) knead order for no pressure-light pressure-weight power-no pressure-weight power- No pressure-light pressure-no pressure is kneaded.
It is preferred that order is kneaded in the pressurization, it is divided into following steps:
(501) time of kneading is kneaded in 0min≤T≤10min using no pressure;
(502) time of kneading is kneaded in 10min < T≤15min using light pressure;
(503) time of kneading is kneaded in 15min < T≤25min using weight power;
(504) time of kneading is kneaded in 25min < T≤30min using no pressure;
(505) time of kneading is kneaded in 30min < T≤40min using weight power;
(506) time of kneading is kneaded in 40min < T≤45min using no pressure;
(507) time of kneading in 45min < T≤55min is kneaded using light pressure;
(508) time of kneading is kneaded in 55min < T≤60min using no pressure.
It is preferred that when the light pressure is kneaded, pressure is 0.3~0.8MPa, and weight power is kneaded, and pressure is 1~6MPa.
It is preferred that fermenting cellar temperature control is at 30 DEG C~40 DEG C in the step (5).
Beneficial effect of the present invention:
1st, for Wild sweet tea fresh leaf initial when, tealeaves is more fragile, is first kneaded using no pressure, protects blade surface not Destroyed, tea juice does not go out also, then is subject to light pressure and kneads, and tea juice is gradually overflowed, and blade starts to moisten, then is subject to weight power and rubs Twist with the fingers, kneaded and loosened with no pressure halfway, then be subject to weight power and knead, until tealeaves shapes substantially, then kneaded and put using no pressure Pine, then kneaded using light pressure, prevent tealeaves from rubbing fringe shape, finally kneaded using no pressure;Prepared using the kneading in technique Black tea, while tealeaves bar shaped is kept, ensure that the rate of kneading of tealeaves reaches 70~85%.
2nd, the black tea prepared using the technique has that bar rope is stout and strong, tight knot is justified straight, color and luster Wu Run, tea and given off a strong fragrance, soup look Glow, the features such as mellow in taste, black tea quality prepared by Shiqian Wild sweet tea can be effectively increased.
Embodiment
Tuberculosis specific embodiment is limited technical scheme is further below, but claimed Scope is not only limited to made description.
In certain embodiments, the preparation method of wild sweet tea black tea, comprises the following steps:
(1) pluck:Using Wild sweet tea as fresh leaf, the Ching Ming Festival front and rear harvesting one bud one leaf, two leaves and a bud, and choose;
(2) sun withering:The fresh leaf of selection in step (1) is uniformly spread on bamboo hedge, per 2~5kg of hedge, 16:00~17: 00, place sun withering in the sun;
(3) wither:The blade that step (2) is handled through sun withering, spread under low temperature, until blade withers, blade face color becomes Deep, blade softens;
(4) knead:Using tea twisting machine, kneaded, time of kneading 60min, kneaded using pressurization kneading in technique Until tea juice no longer flows out and sends delicate fragrance, tea rolling percentage of damage is 70~85%;
(5) ferment:The tealeaves kneaded is put into fermenting cellar and fermented, fermentation time is 6~8 hours, and blade is changed into deep Ferment and complete during brown;
(6) dry:The tealeaves fermented is put into heating chamber to be dried, dried at twice, first drying temperature is 65 DEG C~75 DEG C, the time, secondary drying temperature was 35 DEG C~45 DEG C at 1~3 hour, 3~5 hours time;
(7) finished product packing:Dried tealeaves, reject impurity, packaging, you can.
In certain embodiments, low temperature control is uniform with 1.5-2.5cm thickness at 24 DEG C~30 DEG C in the step (3) Spread on bamboo mat, dry in the air to water content 53%-60%.
In certain embodiments, in the step (4), tea twisting machine is per barreled 8~15kg of tealeaves, rotating speed 60 Turn/min.
In certain embodiments, the pressurization in the step (4) kneads order as no pressure-light pressure-weight power-without pressure Light pressure-the no pressure of power-weight power-no pressure-is kneaded.
In certain embodiments, order is kneaded in the pressurization, is divided into following steps:
(501) time of kneading is kneaded in 0min≤T≤10min using no pressure;
(502) time of kneading is kneaded in 10min < T≤15min using light pressure;
