Organic green tea production system by combining blanching tea leaves and two-stage fixation

Abstract

The invention discloses an organic green tea production system by combining blanching tea leaves and two-stage fixation. The organic green tea production system comprises a tea leaf blanching device, an airing device, a roller fixation device, a microwave fixation device, a strip tidying machine, a baking machine and a fragrance enhancing machine, wherein the microwave fixation device comprises a third box body, and an upper conveyor belt and a lower conveyor belt which are horizontally and oppositely arranged up and down are arranged in the third box body; the conveying direction of the upper conveyor belt is opposite to that of the lower conveyor belt; a feed end of the upper conveyor belt and a discharge end of the lower conveyor belt are positioned on the outer side of the same end part of the third box body. In the technical scheme, the microwave fixation device and the roller fixation device are used in a combined manner, so that the tea leaves are cleaned during blanching tea leaves and color fixation is performed during first-stage fixation; the roller fixation device is used for forming the fragrance of the tea leaves and promoting a non-enzymatic chemical reaction during the first-stage fixation, so that the quality of tea soup is improved, the tea soup is mellow, fresh and brisk, and besides, the tea leaves can have the fragrance of chestnuts; the microwave fixation device is used for promoting the color of the tea leaves and protecting the color of the tea leaves during second-stage fixation, so that the color of the finished tea leaves is dark green and bright.

Description

technical field [0001] The invention relates to the field of tea production equipment, in particular to a combined scalding-secondary green tea production system for organic green tea. 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. How...

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
