Embodiment 1

[0030] Pick 5kg of fresh leaves of Lingyun Pekoe tea with 1-3 leaves in a bud. Thinly spread fresh leaf raw materials on a bamboo sieve and move them outdoors for photothermal withering. The surface temperature of photothermal withering is 25°C, and the time is 25 minutes. The water loss rate of fresh leaves is 7%, and the tea leaves after photothermal withering are obtained. , and then carry out spreading greening and greening processing to it successively. Spreading green is to spread 60min under the condition of room temperature of 20 DEG C in the blue green booth; described making green is to shake green and cool green and repeat alternately 2 times, each time of shaking green and green is 10min, each time of drying green and green for 1h, and the speed of shaking green and green is 30 revolutions / min. The tea leaves after greening are spread out, and the temperature is controlled and withered for 15 hours at a temperature of 25° C. and a relative humidity of 60%, to obta...

Embodiment 2

[0034] Pick 5kg of fresh leaves of Lingyun Pekoe tea with 1-4 leaves in a bud. Thinly spread the raw materials of fresh leaves on a bamboo sieve and move them outside for photothermal withering. The surface temperature of photothermal withering is 28°C, and the time is 30 minutes. The water loss rate of fresh leaves is 8%, and the tea leaves after photothermal withering are obtained. , and then carry out spreading greening and greening processing to it successively. Green spreading is to spread green green at room temperature at 18°C ​​for 80 min in a green stand; the green green is shaken and cool green repeated alternately once, and the time for shaking green green is 5 minutes each time, and the time for drying green green is 1.5 hours each time. The speed is 50 revolutions / min. The tea leaves after greening are spread out, and the temperature is controlled and withered for 14 hours at a temperature of 26° C. and a relative humidity of 70%, so as to obtain the temperature ...

Embodiment 3

[0039] Pick 5kg of fresh leaves of Lingyun Pekoe tea with 1-4 leaves in a bud. Thinly spread the raw materials of fresh leaves on a bamboo sieve and move them outdoors for photothermal withering. The surface temperature of photothermal withering is at 30°C for 25 minutes, until the water loss rate of fresh leaves is 5%, and the tea leaves after photothermal withering are obtained. Carry out spreading blue and green processing to it successively again. Green spreading is to spread green green at room temperature at 20°C for 70 minutes in a green stand; the green green is shaken and cool green alternately repeated 3 times, and the time for shaking green green is 4 minutes each time, and the time for drying green green is 2.0 hours each time. The speed is 40 revolutions / min. After greening, the tea leaves are spread out and withered under temperature control for 18 hours at a temperature of 20°C and a relative humidity of 55%. The temperature-controlled and withered tea leaves a...

Abstract

The invention relates to a method for preparing nectar-flavor black tea from Lingyun pekoe. The method comprises the following steps: 1, picking fresh leaves; 2, withering for 25-30 minutes under a photo-thermal condition at the temperature of 25-30 DEG C, spreading, and shaking; 3, carrying out temperature control withering for 14-20 hours under the conditions that the temperature is 20-26 DEG C and the relative humidity is 55-80%; 4, carrying out primary rolling, namely carrying out air rolling, slight pressing, heavy pressing and slight pressing; 5, fermenting for 3-6 hours under the condition that the temperature is 23-26 DEG C and the relative humidity is above 95%; 6, carrying out primary drying, namely controlling the temperature at a gross fire air inlet to be 120 DEG C, and drying until the water content is 50-60%; 7, carrying out stack-covering for 1-3h under the conditions that the temperature is 25-27 DEG C and the humidity is above 90%; 8, re-rolling, namely carrying out slight pressing, heavy pressing and slight pressing; 9, drying until the water content is 5-6% with a full fire at the temperature of 100-120 DEG C so as to obtain the nectar-flavor black tea. The nectar-flavor black tea is compact and even in tea bars, black-bloom and glossy in color, lasting in nectar flavor, fresh and mellow in taste, after-taste and sweet, and tea water is red and bright.
