Embodiment 1

[0022] The preparation method of eagle tea, its concrete steps are:

[0023] A. Pretreatment: Pick tea greens at 5-8 o'clock in the morning on a sunny day, soak them in water (1.5 times the quality of tea greens) for 8 minutes, wash and set aside;

[0024] B. Withering: first put the pretreated green tea outside and spread it out for 2 hours, then move it into a 36°C oven for hot air drying for 18-22 hours to a water content of 20%;

[0025] C. Stacking: Spread the Eagle Book tea leaves with a water content of 20% (thickness: 24cm) in a dry container and place them for 4.5 hours;

[0026] D. kneading: kneading the finished green tea until the strip rate ≥ 80%, and the cell destruction rate is 55%;

[0027] E. Drying: Carry out infrared drying through the kneaded tea green (the distance between the tea green and the radiation source is 15cm, the temperature is 90° C., and the time is 60 min).

Embodiment 2

[0029] The preparation method of eagle tea, its concrete steps are:

[0030] A. Pretreatment: Pick tea greens at 5-8 o'clock in the morning on a sunny day, soak them in water (2 times the quality of tea greens) for 12 minutes, wash and set aside;

[0031] B. Withering: first put the pretreated green tea outside and spread it out for 3 hours, then move it into a 32°C oven for hot air drying for 18-22 hours until the water content is 25%;

[0032] C. Stacking: Spread the Eagle Book tea leaves with a water content of 25% (thickness is 27cm) in a dry container and place them for 4 hours;

[0033] D. Kneading: Knead the green tea that has been finished until the strip rate is ≥ 80%, and the cell destruction rate is 60%;

[0034] E. Drying: Carry out infrared drying (the distance between the green tea and the radiation source is 16cm, the temperature is 93° C., and the time is 45 min) through the kneaded green tea.

Embodiment 3

[0036] The preparation method of eagle tea, its concrete steps are:

[0037] A. Pretreatment: pick tea greens at 5-8 o'clock in the morning on a sunny day, soak them in water (1.75 times the quality of tea greens) for 10 minutes, wash and set aside;

[0038] B. Withering: first put the pretreated green tea outside and spread it out for 2.5 hours, then move it into a 35°C oven for hot air drying for 18-22 hours to a water content of 23%;

[0039] C. Stacking: Spread the Eagle Book tea leaves with a water content of 23% (thickness is 25cm) in a dry container and place them for 4 hours;

[0040] D. Kneading: Knead the green tea that has been finished until the strip rate ≥ 80%, and the cell destruction rate is 58%;

[0041] E. Drying: Carry out microwave vacuum drying (vacancy is-0.093Mpa, radiation intensity is 4.5kW, transmission speed is 210r / min, the time is 35min) through the kneading green tea.
