  • Patent number: 4201528
    Abstract: Fittings for reducing cracking in soap bars including protrusions on the end flight on the worm or auger of a soap plodder to break up the glazed layer of soap formed by the wiping action of the end flight on the soap as it is discharged. The plodder is provided with a cone nozzle and fittings are provided for eliminating the spiral movement of the soap mass and forming a laminated bar by extrusion through aligned slots. The concept of the invention also includes the elimination of the central or the spongy mass of soap and the formation of a harder grain structure for the soap.
    Type: Grant

  • Patent number: 4141947
    Abstract: A high speed continuous process for making variegated soap bars is disclosed. Soap chips and an emulsion of minor soap ingredients are each continuously supplied to a mixer. The output of the mixer is a homogenized and variegated soap mass that is refined, plodded in a vacuum plodder, cut into soap bars and finally pressed.

  • Patent number: 4096221
    Abstract: Soap worked in a plodder with introduction of a color dye for color striation of the extruded column is extruded through a die plate that has a rectangular opening corresponding to the major face dimensions (length and width) of the product bar so that the extrusion grain is perpendicular to the major faces, and the extruded column is severed at distances equal to the product bar thickness to provide blanks that are pressed in a direction parallel to the extrusion grain to form the product bar. Special locations for color introduction are provided and a unique "carrara" marble effect is produced in the bar.

  • Patent number: 3950122
    Abstract: This invention relates to an apparatus for high intensity shear refining of soap in a soap extruder including at least one rotating auger in a housing for high intensity shear mixing of a mass soap ranging from 3,000 to 40,000 shear cuts per minute, the auger including a shank having a plurality of flights and kneader blocks. The soap extruder includes a housing having a barrel bore for receiving said auger with said auger terminating short of said bore to form a free space, an extrusion outlet extending from said bore, a nozzle plate is secured to said housing in alignment with said extrusion outlet. The nozzle plate has at least one inwardly tapering aperture of lesser diameter than that of said extrusion outlet.

  • Patent number: 3947200
    Abstract: The invention relates to an apparatus and process for producing striated soap bars using a high intensity mixer extruder. A soap mass is levigated and homogenized in a high intensity mixer barrel and forced into a dye injection assembly wherein dye is injected into the soap mass. The soap mass with the injected dye is then forced through conically tapered nozzles to form a striated soap bar.
