Problems solved by technology

[0004] The greening process has a great impact on the quality of tea. If the greening is too much, the green leaves will lose too much water, which is not conducive to shape; if the greening is not sufficient, the hydrolysis and conversion of tea polyphenols, protein and other components in fresh leaves will not be sufficient, and the finished product will taste green and astringent. Heavy
[0005] At present, most of the roller degreening machines are used, but when the drum degreening machine is used, the water vapor in the cylinder is not distributed smoothly, and it is easy to stick the leaves in the cylinder and the mouth of the cylinder to form a burnt smell, which affects the color of the tea leaves, while the pot type degreening machine By making the temperature of the pot high first and then low, it can reduce red stalks and red leaves, and avoid smoke burnt, and it is easy to kill thoroughly and evenly, so as to obtain the green leaves that meet the requirements.

Embodiment Construction

[0017] Select fresh and tender tea leaves, and then place the fresh tea leaves at room temperature to cool for 2-3 hours, and lose 10%-20% of water; use the roller greening machine for the first greening of the tea leaves after cooling, and the temperature is controlled at 200°C-300°C , the passing time is controlled within 2-3 minutes, and the tea greens that have been greened for the first time are passed through the cooling air-conditioning room through the conveyor belt, and the leaf temperature is quickly dropped to 30°C-35°C, and then sent to the pot-type greening machine for the second greening , the temperature of the pot is high first and then low, the temperature is controlled at 220°C-280°C, the passing time is 1-2 minutes, and then the green tea after the second greening is passed through the cooling air-conditioning room through the conveyor belt, and the temperature is quickly cooled to 25°C-30 ℃; the green tea leaves after the second finishing and cooling are sen...

Abstract

The invention discloses a green tea processing technology which comprises the following steps: in the process of de-enzyming, a roll miller is adopted for de-enzyming, then a caldron type de-enzyming machine is adopted for de-enzyming, and then rolling, drying, classification and cold storage are performed. The green tea produced through the green tea processing technology is jade green in color and unique in fragrance.

Description

technical field [0001] The invention relates to a processing technology of green tea. Background technique [0002] The basic structure of the pot-type degreening machine is composed of a leaf frying pot, a leaf frying cavity, a frying hand device, a transmission mechanism and a furnace belly. The advantages of the pot-type de-greening machine are simple structure, easy operation, fast leaf removal, good de-enzyme effect, and low price; but it cannot be operated continuously, it is easy to burn the edge leaves, and the leaves are not clean, and personnel are required to operate the leaves. [0003] The basic structure of the drum type greening machine is composed of a cylinder body, a furnace cavity, a frame and a transmission mechanism, and most of them are integrated with a machine and stove. The model of the drum type greening machine is distinguished by the diameter of the cylinder as the main parameter. It is easy to operate, low in labor intensity, high in efficiency...
