System for producing roasted green tea by combining blanching tea leaves and performing fixation with microwaves

Abstract

The invention discloses a system for producing a roasted green tea by combining blanching tea leaves and performing fixation with microwaves. The system comprises a tea leaf blanching device, an airing device, a roller fixation device, a first spreading-cooling device, a microwave fixation device, a rolling machine, a roasting machine, and a baking device which are connected end to end in sequence, wherein the tea leaf blanching device is used for blanching tea leaves; the airing device is used for airing the tea leaves; the roller fixation device is used for performing first-stage fixation on the tea leaves; the first spreading-cooling device is used for performing first-stage spreading-cooling on the tea leaves; the microwave fixation device is used for performing second-stage fixation on the tea leaves; the rolling machine is used for rolling the tea leaves; the roasting machine is used for stir-frying the tea leaves; the baking device is used for baking the tea leaves. The microwave fixation device and the roller fixation device are used in a combined manner, so that the tea leaves are cleaned during blanching the 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 system for blanching and microwave-cooking combined with frying green tea production. 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 leav...

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
