Soap noodles obtained from above process is stored in storage silo. Noodles are weighed in a batch size for sigma batch mixing operation. The soap noodles are mixed homogeneously into the sigma mixer with other ingredients like colour, specialty chemicals, perfume etc.

The mixed soap noodles are dropped into the receiving hopper of Refining Plodder where the soap is extruded into fine noodle shapes by giving further refining effect to soap mass and partially changing the soap structure. The refined soap is passed through Triple Roll Mill to further homogenize the soap mass to impart shine and luster to soap. The soap film is conveyed by means of a conveyor to the top plodder of Duplex Vacuum Plodder. The top plodder further refines the soap and gives steady continuous feed of soap to bottom extruding plodder. The intersection of two parts of this plodder is vacuum-sealed to remove any traces of air remaining in the soap mass, so that the final extruded soap is compact in structure.

The final plodder extrudes the soap into continuous bar shape. The bars (4-5 cake length) are cut automatically by rotary bar cutter and further cut into small cake as per weight and size requirement of the soap by means of a cake cutting machine.
