Problems solved by technology

[0003] At present, the existing green tea production process can only make green tea into strip green tea or rolled green tea, which can only be packed in bags, which makes the shelf life short, and the tea leaves are scattered around, which not only pollutes the environment, but also wastes a lot of beneficial ingredients , and the green tea produced by the existing technology cannot extend the shelf life through vacuum compression guarantee, which makes the tea sales period of tea enterprises short

Embodiment 1

[0035] A processing method of granular green tea, comprising the following steps in turn:

[0036] Cooling for the first time: evenly spread the picked fresh tea leaves on the mesh on the cooling tank according to the thickness of 1.5cm, and then send natural wind into the cooling tank for 3 hours of ventilation and heat dissipation to obtain moisture 90% fresh tea leaves;

[0037] Steam fixation: send the cooled fresh tea leaves into a steam hot air fixer for steam fixation, and obtain fresh tea leaves with a moisture content of 60%. The steam temperature for steam fixation is 100°C, and the temperature of hot air for steam fixation is 360°C , the time for steaming is 5 minutes;

[0038]Dehydration: Send the finished tea leaves into the dehydration drum of the tea dehydrator for dehydration, and obtain tea leaves with a water content of 50%. When dehydrating, first send natural wind into the dehydration drum through one end of the dehydration drum, and then pass the dehydrat...

Embodiment 2

[0050] A processing method of granular green tea, comprising the following steps in turn:

[0051] Cooling for the first time: evenly spread the picked fresh tea leaves on the mesh on the cooling trough with a thickness of 2 cm, and then send natural wind into the cooling trough for 4 hours of ventilation and heat dissipation to obtain the moisture content 88% fresh leaves of tea;

[0052] Steam fixation: send the cooled fresh tea leaves into a steam hot air fixer for steam fixation, and obtain fresh tea leaves with a water content of 57%. The steam temperature for steam fixation is 105°C, and the temperature of hot air for steam fixation is 380°C , the time for steaming is 7 minutes;

[0053] Dehydration: send the finished tea into the dehydration drum of the tea dehydrator for dehydration, and obtain tea with a water content of 48%. When dehydrating, first send natural wind into the dehydration drum through one end of the dehydration drum, and then pass the dehydration The...

Embodiment 3

[0065] A processing method of granular green tea, comprising the following steps in turn:

[0066] Cooling for the first time: evenly spread the picked fresh tea leaves on the grid on the cooling tank according to the thickness of 2.5cm, and then send natural wind into the cooling tank for 5 hours of ventilation and heat dissipation to obtain moisture Fresh leaves of tea leaves with a content of 85%;

[0067] Steam fixation: send the cooled fresh tea leaves into the steam hot air fixer for steam fixation, and obtain fresh tea leaves with a moisture content of 55%. The steam temperature for steam fixation is 110°C, and the temperature of hot air for steam fixation is 400°C , the steam fixation time is 8 minutes;

[0068] Dehydration: Send the finished tea into the dehydration drum of the tea dehydrator for dehydration, and obtain tea with a water content of 45%. When dehydrating, first send natural wind into the dehydration drum through one end of the dehydration drum, and the...

Abstract

The invention discloses a processing method of granular green tea. The method sequentially comprises the following steps: first-time spreading and airing, steam enzyme deactivation, dehydration, standing, primary rolling, heating, hot rolling, second-time spreading and airing, stoving, third-time spreading and airing, aroma strengthening and fourth-time spreading and airing. The method breaks thetradition that green tea can only be made into strips or rolls, produces the granular green tea, can fix an aroma in tea while prolonging the aroma of the tea so as to leave tea down in the tea and toeffectively prevent the tea down from scattering around and polluting the environment, and can also increase the purity of tea, reduce the bitter and astringent taste of tea, and guarantee the palatability of tea.

Description

technical field [0001] The invention relates to the field of green tea processing, in particular to a processing method of granular green tea. Background technique [0002] Mengding Mountain, where the applicant is located, is the birthplace of the world's tea civilization, the birthplace of the world's tea culture, and it is the earliest place where there are written records in the history of our country to plant tea artificially. From Wang Bao's "Tong Yue" and the legend of Wu Lizhen planting tea trees in Mengshan, which are the earliest records about tea in the world, it can be proved that Mengding Mountain in Sichuan is the origin of tea planting and tea manufacturing. [0003] At present, the existing green tea production process can only make green tea into strip green tea or rolled green tea, which can only be packed in bags, which makes the shelf life short, and the tea leaves are scattered around, which not only pollutes the environment, but also wastes a lot of ben...
