The present application belongs to the technical field of saponin extraction, and particularly relates to a microwave-assisted foam separation and enrichment device and a separation method thereof. The present application uses the separation and enrichment device to perform microwave-assisted water extraction combined with foam separation and enrichment. The method effectively promotes the leaching of saponin, and the extraction rate is close to that of the traditional ethanol leaching method, while the time is greatly shortened to less than 5 minutes, which is much lower than the time of the traditional hot reflux ethanol leaching and hot water extraction, and no organic solvent is needed.
