Embodiment 1

[0020] On April 5, 2014, the applicant's research and development team picked the green normal homogeneous leaves on the branches of the privet tree, cleaned them with clean water; divided the leaves into three types of homogeneous leaves: old, medium and tender according to the color depth of the leaves; and then The petioles and thick veins are peeled off and collected for later use, leaving leaves with only thin veins.

[0021] 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.

[0022] 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. Put the thickness to 1cm, a...

Embodiment 2

[0027] On July 15, 2014, the applicant's research and development team picked the normal green homogeneous leaves on the branches of privet and cleaned them with clean water; divided the leaves into three types of homogeneous leaves: old, medium and tender according to the color depth of the leaves; then peeled off The petioles and thick veins are collected, and the petioles and thick veins are collected for later use, leaving only leaves with thin veins.

[0028] 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.

[0029] 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 the...

Embodiment 3

[0034] On September 23, 2014, the applicant's research and development team picked the normal green homogeneous leaves on the branches of privet and cleaned them with clean water; divided the leaves into three types of homogeneous leaves: old, medium and tender according to the color of the leaves; then peeled off The petioles and thick veins are collected, and the petioles and thick veins are collected for later use, leaving only leaves with thin veins.

[0035] 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.

[0036] 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 puttin...

Abstract

The invention discloses a processing and production method of privet-leave tea. The invention is characterized in that the processing and production method comprises the following nine major steps: picking the privet leaves, peeling the privet 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 tender privet leaves which are freshly picked are peeled, so that the refreshing and pure taste of the privet-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 privet-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 privet leaves are kept and the strips formed by the privet leaves are uniform in shape; the kneading is performed when the privet leaves are hot, so that the privet leaves can be better shaped and the astringent taste of the privet leaves is removed; and the astringent taste can be further covered by the step of refining the aroma. The privet-leave tea produced according to the processing and production method has the advantages that the privet-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 privet-leave tea product.
