Second-level fixation production process for selenium-rich green tea

Abstract

The invention discloses a second-level fixation production process for selenium-rich green tea. The production process comprises steps as follows: at the early stage of fifth-level spreading and cooling, an organic selenium solution is sprayed onto surfaces of tea leaves through a spraying device until the moisture content of the tea leaves reaches 30%-35%; after the fifth-level spreading and cooling, the tea leaves are put in a second drying device for second-level drying processing and spread on a sixth-level spreading and cooling device for sixth-level spreading and cooling at a room temperature after the second-level drying processing is finished, and sixth-level spreading and cooling processing is performed for 30-35 min, wherein the second-level drying processing comprises steps as follows: the tea leaves are dried for 8 min-10 min at the temperature ranging from 100 DEG C to 105 DEG C and then dried at the temperature ranging from 85 DEG C to 90 DEG C until the moisture content of the tea leaves is reduced under 5%. The green tea prepared with the process has a stretched and uniform strip shape and has a bright green color and rich fragrance of chestnuts, tea water is bright green and has a mellow and fresh taste, and the green tea contains rich selenium and is a competitive product in health-care green tea.

Description

technical field [0001] The invention relates to the field of tea production equipment, in particular to a production process for secondary green tea enriched in selenium. Background technique [0002] Yuexi is rich in green tea, among which Yuexi Cuilan is the most famous. At present, the production of Yuexi Cuilan has the following problems: [0003] 1. Due to the implementation of urbanization construction and the discharge of industrial waste gas, there are a lot of dust and harmful substances in the air. These harmful substances will settle and adhere to the surface of the young leaves of tea trees. The young leaves are directly processed after being picked, and people are carrying out It is generally not cleaned when drinking (except for professional tea tasting), so a large amount of harmful substances are drunk. At present, the new processing technology of Yuexi Cuilan adopts hot greening to wash away harmful substances on the surface of tea leaves. However, the hot ...

AI Technical Summary

Problems solved by technology

At present, the new processing technology of Yuexi Cuilan adopts scalding to wash away harmful substances on the surface of tea leaves, but the current scalding equipment is still unable to fully clean the tea leaves and evenly scald the tea leaves

[0004] 2. In modern assembly line tea production systems, rollers are generally used to fix tea leaves, but roller fixes are prone to uneven fixation, red stems, and burnt leaves, which affect the quality of finished tea leaves. Microwave fixation is also used instead of roller fixation Although the microwaving process is uniform, the tea soup made of finished tea leaves is not as mellow and fresh as the drum-finished tea, that is, the quality of the tea soup is poor. way of finishing
