Embodiment 1

[0031] Taking Guangxi Dayezhongcha Fuding Dahao No. 6 as tea raw material, adopting the process of the present invention to automatically and continuously process famous and high-quality green tea, the specific steps are as follows:

[0032] (1) Spread green: Spread the single buds of the picked big-leaf tea evenly on the bamboo sieve, the thickness of which is 2-3cm, the indoor temperature is 18°C, and the relative humidity is 50%. Spread out in the way of wind blowing, and spread out for 3h, 4h, 5h, 6h respectively, and the single bud weight loss rate is respectively 4.2%, 7%, 9%, 10.3% to get the green leaves; processing as follows;

[0033] (2) Finishing: Send green leaves through the fresh leaf conveyor to the drum electric heating machine, set the temperature inside the drum to 300°C, and start feeding when the temperature of the feed inlet rises to 150°C, and the feeding and discharging time is controlled at 80 seconds , the amount of leaves per hour is set to 10 kg, a...

[0047] Taking Guangxi Dayezhongcha Fuyun No. 6 as the tea raw material, adopting the process of the present invention to automatically and continuously process famous and high-quality green tea, the specific steps are as follows:

[0048] (1) Spread green: Spread the single buds of the picked big-leaf tea evenly on the bamboo sieve, the thickness of which is 2-3cm, the indoor temperature is 22°C, and the relative humidity is 60%. Spread out in the way of blowing air, so that the single bud weight loss rate is 9% and the green leaves are spread out;

[0049] (2) Finishing: Send green leaves through the fresh leaf conveyor to the drum electric heating machine, set the temperature inside the drum to 350°C, and start feeding when the temperature of the feed inlet rises to 180°C, and the feeding and discharging time is controlled at 70 seconds , the amount of leaves per hour is set to 15 kg, and the leaves must be killed;

[0050] (3) Microwave simmering: After the drum electric h...

Embodiment 3

[0063] Taking Guangxi Dayezhongcha Fuyun No. 6 as the tea raw material, adopting the process of the present invention to automatically and continuously process famous and high-quality green tea, the specific steps are as follows:

[0064] (1) Spread green: Spread the single buds of the picked big-leaf tea evenly on the bamboo sieve, the thickness of which is 2-3cm, the indoor temperature is 20°C, and the relative humidity is 55%. Spread out in the way of blowing air, so that the single bud weight loss rate is 8% and the green leaves are spread out;

[0065] (2) Finishing: Send green leaves through the fresh leaf conveyor to the drum electric heating machine, set the temperature inside the drum to 320°C, and start feeding when the temperature of the feed inlet rises to 160°C, and the feeding and discharging time is controlled at 75 seconds , the amount of leaves per hour is set to 12 kg, and the leaves must be killed;

Abstract

The invention provides an automatic continuous production process for processing large leaf tea into famous green tea, and relates to the technical field of tea processing. The process comprises the following devices in sequence according to working procedures: a bamboo sieve for tea leaf spreading, a fresh tea leaf conveyor, a drum-type electrothermal enzyme deactivation machine, a conveying belt I, a microwave tempering enzyme deactivation machine, a conveying belt II, a first spreading and cooling platform, a conveying belt III, a rolling machine, a vibration conveying groove, a conveying belt IV, a gross-fire baking machine, a cooling conveying belt, a second spreading and cooling platform, a conveying belt V and a re-drying machine for re-drying. The green tea produced according to the process has the characteristics that the appearance is curly, tea buds and leaves are fat and tender, full coverage of pekoe is realized, the color of tea leaves is leuco green, tea pekoe is aromatic, the color of a tea infusion is peak green, and the color of a tea residue is bright, and is perfect in color, aroma, taste and shape; through mechanical processing of the large leaf tea into the green tea and clean production, the labor intensity is greatly reduced, the working efficiency is improved, the production cost is reduced, and the product quality is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of tea processing, in particular to an automatic continuous production process for processing green tea from large-leaf tea. 【Background technique】 [0002] my country's famous green tea has unique shape and quality, exquisite processing technology, and occupies a pivotal position in my country's tea production and consumption. Taking 2013 as an example, the total national tea production was 1.8901 million tons, with a tea output value of 110.624 billion yuan, while the output of famous green tea was 849,800 tons, with an output value of 75.501 billion yuan, accounting for 44.96% and 68.25% of the national total respectively. It can be seen that the economic efficiency of famous and high-quality green tea is very prominent. The origin of my country's famous green tea is mostly hand-made tea, which has high labor intensity, low work efficiency, high cost, poor benefit, unstable product quality, and cannot ...
