Problems solved by technology

However, there is a greening step, and the environmental conditions are not well controlled, resulting in more damage to the greening chlorophyll, yellowing of the leaves, and loss of various beneficial substances, resulting in a reduction in the quality of tea
In addition, the tea rolling process does not fully grasp the rolling, resulting in varying degrees of damage to the fiber structure of the rolled tea leaves, and the quality of the processed tea leaves is not high.

Abstract

The invention discloses a processing technology of Yuexi Cuilan. The processing technology of Yuexi Cuilan comprises the following steps: S1, picking one bud and one leaf or one bud and two leaves toinitially display fresh leaves; S2, spreading and airing: spreading and airing fresh tea leaves; S3, water-removing: performing water-removing after the tea leaves are spread and aired; S4, rolling: rolling the tea leaves by utilizing the residual temperature after water vapor of the water-removed tea leaves is emitted completely, and spreading for cooling after the rolling; S5, drying: firstly drying at high temperature, spreading for cooling after the tea leaves are removed from a machine, and then drying at low temperature. The tea leaves prepared by the invention are green in luster, tangyin aroma, high in tea leaf integrity, high in health care value and good in economic benefit.
