PROBLEM TO BE SOLVED: To provide a system for automatically wilting a raw leaf, capable of sequentially and automatically carrying out a sunlight wilting step, a leaf-shaking step and a still-standing and wilting step by devices and conveying means, and stably and precisely carrying out the wilting process of the raw leaf.SOLUTION: The system for automatically wilting the raw leaves is equipped with an electromagnetic-wave wilting device 1 for carrying out an ultraviolet wilting step by irradiating the raw leaves with ultraviolet rays while conveying the raw leaves, a leaf-shaking device 2 for carrying out the leaf-shaking step by imparting fine injuries while conveying the tea leaves, and a still-standing and wilting device 3 for carrying out the still-standing and wilting step while conveying the tea leaves. The conveying means are arranged between the electromagnetic wave wilting device 1 and the leaf-shaking device 2, and between the leaf-shaking device 2 and the still-standing and wilting device 3, and the ultraviolet-wilting step by the electromagnetic wave wilting device 1, the leaf-shaking step by the leaf-shaking device 2, and the still-standing wilting step by the still-standing wilting device 3 are automatically and successively carried out in the conveying means.COPYRIGHT: (C)2010,JPO&INPIT【課題】日光萎凋工程、揺青工程及び静置萎凋工程を装置及び移送手段にて順次自動的に行うことができるとともに、生葉の萎凋工程を安定且つ確実に行わせることができる生葉の自動萎凋システムを提供する。【解決手段】生葉を搬送しつつ当該生葉に対して紫外線を照射して紫外線萎凋工程を行うための電磁波萎凋装置1と、当該茶葉を搬送しつつ微小な傷を付与して揺青工程を行うための揺青装置2と、当該茶葉を搬送しつつ静置萎凋工程を行うための静置萎凋装置3とを具備し、電磁波萎凋装置1と揺青装置2との間、及び揺青装置2と静置萎凋装置3との間には移送手段が配設され、これら移送手段にて電磁波萎凋装置1による紫外線萎凋工程、揺青装置2による揺青工程、及び静置萎凋装置3による静置萎凋工程が自動的且つ連続的に行われるものである。【選択図】図1
