Embodiment 1

[0019] On June 10, 2014, the applicant's research and development team picked the green and normal leaves on the trunk and side branches of the 2-3-year-old ginkgo tree, and cleaned them with clean water; the leaves were divided into old, medium and tender according to the color of the leaves. homogeneous leaves; then peel off the petiole and thick veins, and collect the petioles and thick veins for later use, leaving only the leaves with thin veins.

[0020] Then cut the leaves into small square leaves with a side length of 1 cm, place the small leaves on a spreading green tray for 2 hours, spread the thickness of 2 cm, and turn it gently every 30 minutes.

[0021] Then put the peeled petiole and thick leaf veins into the boiler, add water to cook, and use the steam generated in the boiler to complete the greening; put the small leaves on the conveyor belt of the steam greening machine, put them in at a constant speed, spread them evenly, and spread them after putting them in....

Embodiment 2

[0026] On July 10, 2014, the applicant's research and development team picked the green normal leaves of the trunk and side branches of the 2-3-year-old ginkgo tree, cleaned them with clean water, and divided the leaves into three categories: old, medium, and tender according to the color of the leaves Homogenous leaves; petioles and thick veins are then stripped and collected for later use, leaving leaves with only fine veins.

[0027] Then the leaves were cut into small square leaves with a side length of 2 cm, and the small leaves were placed on a spreading green tray for 2.5 hours, with a thickness of 2.5 cm, and gently turned once every 30 minutes.

[0028] Then put the peeled petiole and thick leaf veins into the boiler, add water to cook, and use the steam generated in the boiler to complete the greening; put the small leaves on the conveyor belt of the steam greening machine, put them in at a constant speed, spread them evenly, and spread them after putting them in. Th...

Embodiment 3

[0033] On August 10, 2014, the applicant's research and development team picked the green normal leaves of the main trunk and side branches of ginkgo trees aged 2-3 years, and cleaned them with clean water; the leaves were divided into three categories: old, medium and tender according to the color of the leaves Homogenous leaves; petioles and thick veins are then stripped and collected for later use, leaving leaves with only fine veins.

[0034] Then cut the leaves into small square leaves with a side length of 3 cm, place the small leaves on a spreading tray for 3 hours, and spread them to a thickness of 3 cm, and turn them gently every 30 minutes.

[0035] Then put the peeled petiole and thick leaf veins into the boiler, add water to cook, and use the steam generated in the boiler to complete the greening; put the small leaves on the conveyor belt of the steam greening machine, put them in at a constant speed, spread them evenly, and spread them after putting them in.

Abstract

The invention discloses a processing and production method of gingko-leave tea. The invention is characterized in that the processing and production method comprises the following nine major steps: picking the gingko leaves, peeling the gingko leaves, airing the enzymes, deactivating the enzymes, air-drying, kneading, screening and classifying, refining the aroma, dehydrating and the like. The processing and production method has the beneficial effects that the leaf stems and the thick leaf veins of the fresh and tender gingko leaves which are picked in proper season are peeled, so that the refreshing and pure taste of the gingko-leave tea can be preserved; enzymes in the leaf stems and the thick leaf veins are further deactivated by water vapor, so that the pure aroma of the gingko-leave tea can be further ensured; the enzyme deactivation and the air-drying are performed on a conveyer belt so that the shapes of the gingko leaves are kept and the strips formed by the gingko leaves are uniform in shape; the kneading is performed when the gingko leaves are hot, so that the gingko leaves can be better shaped and the astringent taste of the gingko leaves is removed; and the astringent taste can be further covered by the step of refining the aroma. The gingko-leave tea produced according to the processing and production method has the advantages that the gingko-leave tea is uniform in appearance, jade-green in color, refreshing and thick in aroma, dark-green and transparent in tea-soup color, tender and mellow in tea-soup taste as well as exquisite and fragrant tea-soup flavor. The processing and production method greatly improves quality of the gingko-leave tea product.
