Selenium-enriched organic green tea continuous production system with secondary fixation function

Abstract

The invention discloses a selenium-enriched organic green tea continuous production system with a secondary fixation function. According to the continuous production system, a fifth spreading cooling device is arranged on a spreading cooling table board, and a spraying device for spraying an organic selenium solution to tea leaves is arranged above the spreading cooling table board and connected with an organic selenium solution storage tank; a microwave fixation device comprises a third box body, an upper conveyor belt and a lower conveyor belt are horizontally and oppositely arranged up and down in the third box body, and the conveying directions of the upper conveyor belt and the lower conveyor belt are opposite. According to the technical scheme, the microwave fixation device and a roller fixation device are jointly utilized, so that the tea leaves are cleaned and subjected to primary fixation for color setting during blanch fixation; the roller fixation device is used for performing initial fixation to facilitate tea fragrance forming and non-enzymic chemical reaction, the tea soup quality is improved and becomes mellow and fresh, and meanwhile, the tea acquires chestnut fragrance; the microwave fixation device is used for performing secondary fixation and used for enhancing and retaining tea color, and accordingly, the color of finished tea is dark green, smooth and bright.

Description

technical field [0001] The invention relates to the field of tea production equipment, in particular to a continuous production system for selenium-enriched organic green tea secondary deenzyming. 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...

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
