Problems solved by technology

The selected raw materials for the silver needle-shaped tea leaves are incompletely unfolded tea leaves. If the tea buds grow too fast, the picking time will be relatively short, the yield will be too low, and there will be no economic benefits.
The fried finished tea leaves are prone to breakage due to their silver needle shape

Embodiment 1

[0024] (1) Material selection: select the single bud of Zhenong 117 clone tea leaves, the length of the selected tea leaves is 1.6-2.2cm, the shape is required to be round and straight like a needle, and the color is light green and bright;

[0025] (2) Dry green: spread the picked raw materials in a bamboo container and place them in a cool and ventilated place. The thickness of the spread is 1.5cm, and the time of drying green is 8 hours, so that the water content of the fresh leaves is reduced to 70%-75%. , Turn the tea leaves every 1.5 hours during the drying process;

[0026] (3) Finishing: The temperature of the pot is 155°C, stir-fry quickly, and stir-fry until the leaf color changes from bright green to dark green, the stems continue to break, the grass gas disappears, the water content drops to 40%-50%, and the killing time lasts for 6 minutes;

[0027] (4) Spreading and airing: the fresh leaves after high-temperature killing are cooled and dissipated to dissipate the...

Embodiment 2

[0033] (1) Material selection: select the single bud of Zhenong 117 clone tea leaves, the length of the selected tea leaves is 1.6-2.2cm, the shape is required to be round and straight like a needle, and the color is light green and bright;

[0034] (2) Dry green: spread the picked raw materials in a bamboo container and place them in a cool and ventilated place. The thickness of the spread is 1.8cm, and the time for drying green is 10 hours, so that the water content of the fresh leaves is reduced to 70%-75%. , Turn the tea leaves every 1.2 hours during the drying process;

[0035] (3) Finishing: the pot temperature is 160°C, stir-fry quickly, and stir-fry until the leaf color changes from bright green to dark green, the stems continue to break, the grass gas disappears, the water content drops to 40%-50%, and the killing time lasts for 7 minutes;

Embodiment 3

[0042] (1) Material selection: select the single bud of Zhenong 117 clone tea leaves, the length of the selected tea leaves is 1.6-2.2cm, the shape is required to be round and straight like a needle, and the color is light green and bright;

[0043] (2) airing green: the raw material of plucking is aired in the bamboo container and placed in a cool and ventilated place, the airing thickness is 2cm, and the airing time is 12 hours, so that the water content of fresh leaves is reduced to 70%-75%, Turn the tea leaves every 1 hour during the drying process;

[0044] (3) Finishing: The temperature of the pot is 175°C, stir-fry quickly, and stir-fry until the leaf color changes from bright green to dark green, the stems continue to break, the grass gas disappears, the water content drops to 40%-50%, and the killing time lasts for 8 minutes;

[0045] (4) Spreading and airing: the fresh leaves after high-temperature killing are cooled and dissipated to dissipate the water vapor in the...

Abstract

The invention provides a selenium-rich needle-shaped tea and a manufacturing method thereof. Zhenong 117 clonal tea leaves planted in selenium-rich districts are selected and used as raw materials oftea leaves, the length of the tea leaves are selected to be 1.6 to 2.2 cm, and the manufacturing process comprises the steps of material selection, cooling of green leaves, killing, spreading, rolling, moisture regain, drying and packaging. The tea has the beneficial effects that the Zhenong 117 clonal tea leaves are selected and used, the germination is early in spring, the buds are strong, the body is robust, the leaves are expanded slowly, the raw materials required for the needle-shaped tea can be picked continuously in spring, summer and autumn, the picking period is long, the collectionand processing rate is high, and the economic benefit is high; the moisture regain step is added before drying, and the tenacity of the tea can be strengthened, so that the needle-shaped tea is unlikely to fracture.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a method for preparing selenium-enriched silver needle-shaped tea. Background technique [0002] With the continuous enrichment of material life, a healthy and high-quality life is what modern people are constantly pursuing. Tea drinks already have all the health functions and extend them to integrate taste, health and appreciation. [0003] Pingli County, located in the southeast of Shaanxi Province, is a famous tea county in Shaanxi Province. It has a superior climate and is far away from industrial pollution. Its soil is rich in selenium, and its tea is rich in selenium, which is beneficial to the human body. The selected raw materials of the silver needle-shaped tea leaves are incompletely unfolded tea leaves. If the leaves of the tea buds grow too fast, the picking time will be relatively short, the yield will be too low, and there will be no economic bene...
