Embodiment 1

[0018] A preparation process of eucommia leaf green tea comprises the following steps: (1) selection of original leaves: the original leaves of eucommia ulmoides are used from early June to mid-October in the north, fresh and complete leaves of eucommia are picked, and the petioles of eucommia leaves are removed. After the petiole is removed, soak it in 2% salt water, take it out and clean it with water after soaking; (2) pretreatment of the original leaf: spread the original leaf in the air until it is slightly wilted, and the moisture content of the original leaf can be reduced to 70%. Leaves were cut into strips; (3) a prismatic drum frying machine with a drum inner diameter was used to fry once, the frying temperature was 140°C, and the leaves were to be fried until the water content of the leaves was 3%, and the finished Eucommia leaf green tea Example 1 was obtained.

Embodiment 2

[0020] A preparation process of eucommia leaf green tea comprises the following steps: (1) selection of original leaves: the original leaves of eucommia ulmoides are used from early June to mid-October in the north, fresh and complete leaves of eucommia are picked, and the petioles of eucommia leaves are removed. After the petiole is removed, soak it in 2% salt water, take it out after soaking, and clean it with clear water; (2) Pretreatment of the original leaf: spread the original leaf in the air until it is slightly wilted, and the moisture content of the original leaf can be reduced to 60%. Cut the leaves into strips; (3) use a prismatic drum frying machine with a drum inner diameter to perform one frying at a temperature of 150° C., and wait until the moisture content of the leaves is 8%, to obtain the finished Eucommia leaf green tea Example 2.

Embodiment 3

[0022] A preparation process of eucommia leaf green tea comprises the following steps: (1) selection of original leaves: the original leaves of eucommia ulmoides are used from early June to mid-October in the north, fresh and complete leaves of eucommia are picked, and the petioles of eucommia leaves are removed. After the petiole is removed, soak it in 2% salt water, take it out after soaking, and clean it with clear water; (2) Pretreatment of the original leaf: spread the original leaf in the air until it is slightly wilted, and the moisture content of the original leaf can be reduced to 65%. Leaves were cut into strips; (3) a prismatic drum frying machine with a drum inner diameter was used to fry once, the frying temperature was 160°C, and the leaves were to be fried until the water content of the leaves was 6%, and the finished Eucommia leaf green tea Example 3 was obtained.
