Embodiment 1

[0019] On May 2, 2014, the applicant's research and development team picked the green and normal leaves on the top of the sweet potato vine, 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; and then peeled off the petioles and thick veins, and collect petioles and thick veins for later use, leaving only 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. Put the thickness of ...

Embodiment 2

[0026] On May 30, 2014, the applicant's research and development team picked the green normal leaves on the top of the sweet potato vine, 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, and collect petioles and thick veins 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.

Abstract

The invention relates to a processing and making method of sweet potato leaf tea. The processing and making method is characterized by comprising nine steps as follows: picking, stripping, tedding, fixation, drying with wind, rolling, sieving, aroma-increasing, dehydration and the like. The processing and making method has the beneficial effects that in appropriate seasons, fresh and tender sweet potato leaves are picked, and leaf stems and crude veins are stripped, so that clean and pure degrees of the sweet potato leaf tea can be maintained, and steam of the leaf stems and the crude veins is used for performing steam fixation, and pure fragrance of the sweet potato leaf tea can be further guaranteed; fixation and drying with wind can be performed through a conveyor belt, so that the shape of leaf blades can be maintained, and shapes, appearances and dimensions of the formed tea are uniform; rolling is performed when the dried tea is hot, so that perfect models can be obtained, bitterness in the sweet potato leaves can be removed, and after the aroma increasing, the bitterness can be further covered.
