The inlet of ferment tank carries water into body of ferment tank. Water is a medium for oscillator of ferment tank to decompose internal tissue of unfermented leaves and subsequently discharge water from outlet. After discharging water from outlet, the vacuum machine will make a vacuum condition for leaves to ferment in anaerobic state. After anaerobic fermentation, intake apparatus will start and fill oxygen into body of ferment tank, and then drum will be driven by motor. The two steps, anaerobic fermentation and rolling with oxygen, work repeatedly. Its can reduce production time and improve r-amino butyric acid content.本發明係由發酵槽之進水端導入水源至槽體,並利用其發酵槽內部之振盪器,以水源為介質,靠著水源振盪之效果達到分解未發酵葉子的內部組織,其後由排水端排出水源,水源排出後,即可進行厭氧發酵,厭氧發酵係利用真空機使槽體內部形成一真空狀態後則可使葉子形成一厭氧發酵之狀態,厭氧發酵完成後則可開始進行有氧攪拌,有氧攪拌係啟動進氣裝置將氧氣填充入槽體並利用馬達帶動筒體轉動,反覆進行厭氧發酵及有氧攪拌,其步驟可減縮製茶時間及提升茶葉的r-胺基丁酸含量,並可提升其產品價值,進而提升其實用價值者。1‧‧‧發酵槽11‧‧‧槽體12‧‧‧振盪器13‧‧‧進水端14‧‧‧排水端15‧‧‧密合蓋151‧‧‧把手16‧‧‧膠體2‧‧‧中空滾筒21‧‧‧筒體22‧‧‧轉動馬達23‧‧‧開口24‧‧‧滑蓋25‧‧‧孔洞3‧‧‧真空機4‧‧‧進氣裝置
