Embodiment approach 1

[0021] The preparation process of the delicate fragrance type Tieguanyin which is not easy to be oxidized at normal temperature comprises the following steps carried out in sequence:

[0022] a. Green picking: Tieguanyin green tea with one bud and three leaves is picked between 12:00 and 16:00; green tea is planted on loess or red soil at an altitude of 700 to 800 and is planted with cow dung or / and sheep dung The red core and crooked tail tea green used as fertilizer;

[0023] b. Sunshine: During the time period from 16:00 to 17:30, the thickness of the dark green leaves is between 2 and 3 cm. Under the premise that the dark green does not die, the green sun is finished until the green is soft and soft. Sun drying, at this time, the natural fermentation degree of the green tea basically reaches about 13%; turn the green tea at least once during the drying process;

[0024] c. Dry green: dry green at room temperature for 40 to 50 minutes before shaking green;

Abstract

The invention discloses a preparation process for constant-temperature fresh scent refined Tie Guanyin difficult to oxidize. The preparation process comprises the following steps: picking Tie Guanyin fresh leaves; sun-withering the Tie Guanyin fresh leaves; carrying out cooling of green leaves; carrying out rocking of green leaves; de-enzyming the green leaves; rolling and wrapping the green leaves; roasting the green leaves; and obtaining a finished product, wherein the step of carrying out rocking of green leaves comprises the steps: firstly rocking the green leaves in a green leaf rocking machine for 3-5 minutes and then paving the green leaves for 100-120 minutes; then rocking the green leaves for 8-10 minutes and then paving the green leaves for 170-180 minutes; then rocking the green leaves for 25-33 minutes and then paving the green leaves for 240-250 minutes; and finally, rocking the green leaves for 35-65 minutes and then paving the green leaves for 300-360 minutes. The tea leaves prepared by the process disclosed by the invention can be stored for at least 18 months at normal temperature and has no obvious color changes, and even if the tea leaves are stored at high temperatures for a week, the appearance of the tea leaves is basically not changed; with the increase of placing time, the quality of tea soup is enhanced on the contrary, so that the output of the tea leaves is effectively improved as a result of limitation of storage conditions.

Description

technical field [0001] The invention relates to a production method of tea leaves, in particular to a production process of a light-flavored refined Tieguanyin which is not easy to be oxidized at room temperature, using fresh Tieguanyin leaves as raw materials. Background technique [0002] my country is the birthplace of tea, and tea is one of the traditional crops for farmers in mountainous areas in my country to get rid of poverty and become rich. Tieguanyin tea is one of the most representative teas in Anxi, Fujian, and one of the top ten famous teas in China. [0003] The Tieguanyin tea leaves produced by the existing Tieguanyin production process are mostly stored in vacuum packaging and the tea leaves are refrigerated. If they are not stored in this way, the tea leaves will be oxidized very quickly, especially the fragrance-type Tieguanyin. If the tea is kept at room temperature and not vacuum-packed for one to two weeks, the color of the tea will change from green t...
