The present invention discloses processing equipment and a method for recycled polyol foam raw material from waste polyurethane, belonging to the technical field of waste polyurethane recycling. The twin-screw extruder of the present invention comprises a casing and two screws arranged in the casing; a plurality of slotting members are arranged on the top of the casing, the plurality of slotting members are arranged along the rotation direction of the screws, and the slotting members are used for cutting grooves on the viscous material and introducing liquid into the grooves through liquid channels. The present invention also discloses a processing method using the above processing equipment for recycled polyol foam raw material from waste polyurethane. In the stage when the material forms a viscous liquid, the present invention uses the slotting members to cut grooves on the surface of the material that gathers from both sides to the middle along with the two screws, and injects liquid into the grooves through the liquid channels arranged on the slotting members. The materials on the two screws start to polymerize and encapsulate the liquid inside the viscous material, which can promote the fusion of the liquid and the viscous material, and solve the problem of solid fragments encapsulated in the discharged viscous material.
