Abstract

An apparatus for mixing and kneading raw materials, such as soap, and extruding the mixture into a predetermined shape. The apparatus includes a cylinder having a rotatable plodder worm shaft, a levigating mechanism disposed at a longitudinal position of the cylinder and including a rotary disc and a fixed disc fixed to the cylinder. The rotary disc and the fixed disc are disposed side by side along the axial direction of the plodder worm shaft and define a plurality of through holes allowing passage of the material in the axial direction. A flow passage forming member is disposed within a moving passage of the material between the rotary disc and the fixed disc and forms a flow passage allowing passage therethrough of fluid maintained at a predetermined temperature. A fluid supplying/exhausting device is provided for supplying the fluid at a predetermined flow rate to the flow passage and exhausting the fluid from the flow passage forming member.
