The invention relates to a double-station stirring oscillation device for grease extraction. The double-station stirring oscillation device comprises a rack, wherein a transverse beam is supported byvertical columns on the rack; a first stirring oscillation mechanism and a second stirring oscillation mechanism are arranged on the rack; the two stirring oscillation mechanisms are of a same structure and comprise extraction tanks, dreg discharge pipelines, driven shafts, stirring osculation components and buckle covers; the extraction tanks are provided with hollow rotating shafts at bottoms; the hollow rotating shafts of the extraction tanks are positioned inside shaft sleeves; inner ends of the dreg discharge pipelines extend into the bottoms of the extraction tanks; the driving shafts are arranged on the rack; the driven shafts are in transmission with the driving shafts through clutches; the driven shafts are in transmission with the hollow rotating shafts through bevel gears; the stirring osculation components comprise stirring motors and vertical stirring shafts; stirring fences are mounted at the lower ends of the stirring shafts; vertical lifting cylinders are mounted on thetransverse beam at the top ; the lower ends of piston rods are connected with the tops of the buckle covers; sliding tracks are mounted on the vertical columns; sliding blocks fixed with the buckle covers are arranged on the sliding tracks.
