The invention relates to a technology and a device for full automatic cloth-free wrapping-twisting of oolong tea. The technology for full automatic cloth-free wrapping-twisting of oolong tea comprises the following steps of 1, automatic tea-feeding, 2, primary twisting, ball-breaking and sifting, 3, heating and primary drying, and 4, secondary kneading and shaping wrapping. The technology cooperates with the device. The device comprises a foundation support, a lifting device, a motor and transmission mechanism, a hydraulic device, a roller device, a guide wheel device, a temperature-control heating device, a wrapping-twisting head device, an automatic door device, and an automatic tea feeding / discharging device. Through the technology and the device, tea green leaves especially such as oolong tea green leaves can be twisted for shaping repeatedly and automatically. The technology and the device realize cloth-free wrapping-twisting, greatly improve wrapping-twisting efficiency, reduce labor intensity and a labor cost and realize continuous and automatic processing of oolong tea.
