Preparation method of Shimen silver needle green tea

Abstract

The invention discloses a preparation method of Shimen silver needle green tea. According to the preparation method, on fine days in early April, fresh leaves picked before 12:00 a.m. every day are uniformly spread in thickness of 1cm in a withering rack and withered for 110-130 minutes, and the fresh leaves are prepared into tea in the afternoon on the day after the water content is reduced by 30%; fresh leaves picked before 20:00 every afternoon are prepared into tea at night on the day by the same method; In preparation of the tea, fixation is performed on the fresh leaves by using an electric stainless steel continuous fixation machine, a fan and a cooling vibrating tank are arranged at an outlet of the fixation machine for performing rapid cooling on the tea subjected to fixation, thetea is uniformly spread in thickness of 1cm in the withering rack for performing cooling after the moisture content of the tea is 48-50% of the moisture content of the original fresh leaves, then thetea is sorted and formed in a sorting machine at temperature of 120 DEG C, and then the tea is cooled and dried until the moisture content of the tea is reduced to 5-7% of the moisture content of theoriginal fresh leaves. The tea prepared by the method disclosed by the invention cannot shed white hairs and has perfect shoot tips.

Description

technical field [0001] The invention belongs to the technical field of tea preparation. Background technique [0002] Shimen Silver Needle Green Tea is produced in Yanjin County, Zhaotong City, Yunnan Province, my country. Its leaves are fresh and tender, the soup color is clear, the taste is fresh, and the taste is mellow and long-lasting. Tea trees are planted in the Wumeng Mountains, where the air is humid and the clouds are shrouded in mist. [0003] The traditional production process of Shimen silver needles is to collect the fresh leaves of small-leaved tea trees picked before 20:00 every afternoon during the Qingming season (except rainy days), and then spread them evenly on a withering rack with a thickness of about 3 cm and wither for about 3 to 5 hours. (The fresh leaves picked in this way will turn black after a long time, and the dehydration is not uniform enough if they are spread thick), and then use a continuous automatic greening machine that uses coal as fu...

AI Technical Summary

Problems solved by technology

The prior art method has at least the following deficiencies: 1. The fresh leaves are withered for 3 to 5 hours by about 3cm thickness. Uniform; 2. The continuous automatic degreening machine uses coal as fuel, and the decapitation temperature can only reach about 200°C, and the decapitation temperature is uneven. The main reason is that the temperature change is affected when adding fuel; If it is too long, it will cause the tea leaves to collide with each other for too long, and the processed Shimen Yinzhen tea will have a smooth appearance, almost all of which will be lost, and 80 / % of the bud tips will be damaged), which will directly affect the vitamin content, tea quality, tea soup, aroma, and taste of the tea. , color, shape, etc.; 4. The production efficiency is not high
