Embodiment 1

[0020] (1) Picking of fresh leaves: Choose high-flavor oolong tea varieties as fresh leaf raw materials, and pick according to the standard of one bud with two or three leaves to keep the tea green evenly. Picking time is 10:00 a.m. in fine weather.

[0021] (2) Airing: In the airing field, the ground temperature is about 30°C, and the fresh leaves are placed on the airing cloth and spread evenly and thinly. The drying time is 30 minutes, and they are turned twice during the period to keep the degree of drying uniform. It is advisable for the leaves to be half drooping, the leaf surface to lose luster slightly, and the grass smell to be emitted, and the weight loss rate is about 10%.

[0022] (3) Greening: Dry the green leaves and move them into the air-conditioned room for greening. The temperature in the air-conditioned room is controlled at 20°C and the relative humidity is 70%. Shaking greens is two processes of shaking greens and cooling greens, which are carried out alt...

[0031] (1) Picking of fresh leaves: Choose high-flavor oolong tea varieties as fresh leaf raw materials, and pick according to the standard of one bud with two or three leaves to keep the tea green evenly. Picking time is 2:00 pm in fine weather.

[0032] (2) Airing: In the airing field, the ground temperature is about 30°C. The fresh leaves are placed on the airing cloth and spread evenly. The drying time is 20 minutes, and they are turned twice during the period to keep the degree of drying uniform. It is advisable for the leaves to be half drooping, the leaf surface to lose luster slightly, and the grass smell to be emitted, and the weight loss rate is about 10%.

[0033] (3) Greening: Dry the green leaves and move them into the air-conditioned room for greening. The temperature in the air-conditioned room is controlled at 18°C ​​and the relative humidity is 80%. There are two processes of shaking greens and cooling greens, which are carried out alternately. The amount of ...

Embodiment 3

[0042] (1) Picking of fresh leaves: Choose high-flavor oolong tea varieties as fresh leaf raw materials, and pick according to the standard of one bud with two or three leaves to keep the tea green evenly. Picking time is 5 pm in fine weather.

[0043] (2) Airing: in the airing field, the ground temperature is about 30°C, and the fresh leaves are placed on the airing cloth and spread evenly and thinly. The drying time is about 45 minutes, and it is turned once during the period to keep the degree of drying uniform. . It is advisable for the leaves to be half drooping, the leaf surface to lose luster slightly, and the grass smell to be emitted, and the weight loss rate is about 10%.

[0044] (3) Greening: Dry the green leaves and move them into the air-conditioned room for greening. The temperature in the air-conditioned room is controlled at 22°C and the relative humidity is 65%. Shaking greens is two processes of shaking greens and cooling greens, which are carried out alte...

Abstract

The invention discloses an independent-fermentation-free pan-fired black tea processing method which comprises the steps of picking fresh leaves, airing the leaves, swinging the leaves, stacking the leaves, rolling the leaves, performing preliminary frying, performing secondary frying, screening the leaves, roasting the leaves and packaging products. According to the independent-fermentation-free pan-fired black tea processing method, the working procedure of independent fermentation during black tea processing is eliminated; furthermore, under the action of a green-tea pan-firing technology, the fermentation can be quickly stopped; contents of tea leaves can be fixed. The technology is simple, the cost is low, and the processed tea has a bright apricot color, tastes sweet and cool, is obvious in sweet and fragrant flavor and meets the taste of modern customers.

Description

technical field [0001] The invention belongs to the technical field of tea product processing, and in particular relates to a processing method of roasted black tea without independent fermentation. Background technique [0002] Fujian Province is a large tea-producing province in my country, rich in tea tree resources and the birthplace of black tea. "Zhengshan Souchong" and "Three Great Kung Fu" are famous all over the world. In the existing black tea processing methods, there is an independent fermentation process, but the fermentation time and temperature are difficult to control, resulting in unsatisfactory degree and uniformity of fermentation, resulting in sour taste, less mellow and refreshing taste of finished tea. Darkness, cloudy soup and other performances have greatly affected the quality and price of the product. [0003] The fresh leaves of varieties suitable for making black tea are used as raw materials, and at a temperature of 22-30°C, an independent ferm...
