PROBLEM TO BE SOLVED: To provide a device for steaming and crumpling tea leaves in one step, enabling reduction in a space for tea manufacturing.SOLUTION: The device includes: a rotary barrel 1 with one end disposed at a level higher than that of another end, rotatable agitation vanes 2 disposed inside the rotary barrel 1 and a control unit 3 for rotation control of the rotary barrel 1 and the agitation vanes 2. Tea leaves "a" and heated steam are supplied from the higher end of the rotary barrel 1, so that the tea leaves "a" are steamed with the steam. At the same time, the tea leaves "a" are compressed between the agitation vanes 2 and the rotary barrel 1 or the rings 7, so that the water component in the tea leaves "a" is squeezed out.COPYRIGHT: (C)2015,JPO&INPIT【課題】蒸し工程と揉み工程とを一工程で行うことによって製茶スペースを小さくする。【解決手段】一端が高く、他端が低くなるように配置された回転胴1と、回転胴1の内部に回転可能に設けられた攪拌羽根2と、上記回転胴1と攪拌羽根2とを回転制御する制御装置3とから構成され、上記回転胴1の高い方の端部から茶葉aと熱せられた蒸気を供給し、蒸気によって茶葉aを蒸すとともに、攪拌羽根2と回転胴1及びリング7との間で押圧して茶葉aの内部の水分を揉み出すことを特徴とする。【選択図】図2
