Burdock leaf extraction device

The burdock leaf extraction device comprises an extraction tank used for containing raw material liquid and a steam generator used for generating steam, and a stirring mechanism used for stirring the raw material liquid is arranged on the extraction tank; the stirring mechanism comprises a stirring part arranged in the extraction tank and a power part for driving the stirring part to rotate. According to the burdock leaf extraction device provided by the invention, the stirring mechanism is arranged to be matched with the steam generator for use, so that steam can be conveyed into the extraction tank from the stirring mechanism, and the steam inlet groove and the steam outlet groove are respectively formed in the rotating shaft and the stirring blades, so that the steam can be uniformly distributed at different height positions in the extraction tank; the steam is further uniformly distributed in different height ranges by utilizing the rotating effect of the rotating shaft, so that raw material solutions at
