摘要： Simplified liquid-solid and liquid-liquid separations after centrifugal extraction are used to extract a target substance from a substance mixture into a solvent. An extraction container has a closed-end cylindrical shape, and is rotated around a central axis by an extractor rotor driven by a motor. The extraction container includes: an opening provided in a bottom portion thereof; and a valve (valve ball) provided at the opening, and opened or closed by a pressure difference between above and below the valve. In extraction, a substance mixture and a solvent are put into the extraction container. The extraction container is repeatedly subjected to normal rotation, pausing, reverse rotation, and pausing to thereby extract a target substance from the substance mixture into the solvent and to separate the liquids into upper and lower layers. Then, an air pressure hose nozzle is connected to an opening in an upper portion of the extraction container, and an inside of the extraction container is pressurized to open the valve at the bottom portion. Thus, the liquids are sequentially discharged from the liquid in the lower layer.
