The invention discloses a lanolin reactive extrusion saponification device and method, and belongs to the technical field of lanolin processing, and the lanolin reactive extrusion saponification method comprises the following steps: adding lanolin, calcium oxide or calcium hydroxide and a phase transfer catalyst into a reaction kettle, heating to 40 DEG C, and uniformly stirring and mixing as raw materials; conveying the raw materials to a screw reaction extrusion all-in-one machine at a uniform blanking speed; and extruding the saponified material to a homogenizer by the cylindrical mouth mold, adding a low alcohol solvent for extraction, and separating liquid and solid phases to obtain a cholesterol-containing lanolin alcohol extracting solution and a lanolin acid calcium solid. The continuous saponification of the wool fat is enhanced by adding a small amount of phase transfer catalyst into calcium oxide or calcium hydroxide through the reaction extrusion process, the calcium chloride conversion step is om
