Definitions

  • the present invention relates to a process and apparatus for continuously producing soap having pearl gloss.
  • soap having pearl gloss is required to be produced in a batch style. That is, the conventional method of producing soap having pearl gloss is disadvantageous in that the operation of giving directional qualities to fish scale incorporated in fused transparent soap material in order to develop pearl gloss therein must be carried out in separate cooling containers. For this reason, it has been impossible to produce such a soap in a continuous manner.
  • an object of the present invention to provide a process for continuously producing soap having pearl gloss without any stirring operation in separate cooling containers by means of a stirring rod and the like using a simple operation wherein fused transparent soap material having incorporated fish scale with directional qualities given is merely poured into a cooling container in order to remove said complicated operations possessed by the prior arts.
  • FIG. 1 is a graphical illustration of a relation between temperature and viscosity of a warm-fused transparent soap material during cooling according to an example of the method of the present invention
  • FIG. 2 is a cross-sectional view of the device according to the present invention.
  • FIG. 3 is a cross-sectional view cut along IIIIII line in FIG. 2;
  • FIG. 4 is a cross-sectional view out along lVIV line in FIG. 2.
  • FIG. 1 shows a relation between temperature and viscosity obtained where 55 parts of degrees alcohol, 5 parts of water and 30 parts of sucrose are added to the soap mass obtained by saponifying a mixed fat composed of 70 parts of beef tallow and 30 parts of coconut oil with an aqueous solution of 30% sodium hydroxide and disolved to prepare warm-fused transparent soap material followed by cooling said soap material to a solid state.
  • a transition temperature region is 46.5:1" C. wherein rapid increase in viscosity with the associated solidification occurs and transition from a liquid state to a solid state takes places.
  • the process according to the present invention comprises adding pearl gloss developing materials such as bismuth oxychloride, fish scale or mica, or materials consisting of mica and other inorganic materials alone or in combination to warm-fused transparent soap material to disperse same therein, cooling the mixture to a temperature range higher, but no more than 1.5 C. higher than a liquid-solid transition temperature region at which rapid increase in viscosity with the associated solidification oc curs during cooling, and pouring the soap material kept at said temperature into a solidifying container to solidify same.
  • pearl gloss developing materials such as bismuth oxychloride, fish scale or mica, or materials consisting of mica and other inorganic materials alone or in combination
  • warm-fused transparent soap material to disperse same therein
  • the temperature at which the warm-fused transparent soap material is poured into the solidifying container is more than 1.5 C. higher than said temperature region, it is impossible to develop pearl gloss design in the re sulting soap.
  • warm-fused transparent soap material to which is added pearl gloss developing material is cooled under stirring to a temperature range higher, but no more than 1.5 C. higher than a liquid-solid transition temperature region at which rapid increase in viscosity with the associated rapid solidification occurs during cooling, said region being inherent in said transparent soap, and then the soap material kept at said temperature region is poured into a solidifying container, whereupon said soap material is solidified with a rapid increase in viscosity and the associated solidification occurs while maintaining the directional qualities of the pearl gloss caused by a stirring prior to pouring and liquid movement during pouring, so that it becomes possible to provide the final product with a uniform pearl gloss design without any stirring operation at all in a cooling container.
  • the method of the present invention may be effectively zzftrried out by means of the apparatus described hereinter.
  • the apparatus according to the present invention comprises the following elements:
  • cooling means 7 is composed of a cylindrical tube which defines cooling jacket 8. Inside said tube the axis of rotation 9 is disposed coaxially with said tube, and scraper for avoiding the formation of a solidified soap layer at the inner wall of the cooling jacket 8 through the attachment of the soap thereto during cooling is equipped with said axis 9 in adjacent relation to said inner wall.
  • scraper 10 the soap supplied from the tank 1 is passed through the cooling means 7 while being subjected to an intimate mixture, so that a satisfactory cooling effect is achieved.
  • the soap is cooled to a temperature higher, but no more than 1.5" C. higher than a liquid-solid transition temperature region by cooling jacket 8 wherein cooling liquid is circulated through cooling liquid passage 11 surrounding the circumference of the cooling jacket 8.
  • the soap thus cooled is delivered into means for giving directional qualities 12 connected to the cooling means 7 wherein the axis of rotation 13 is provided coaxially with the axis of rotation 9 and supported thereby, and the axis of rotation 13 is equipped with stirring blade 14.
  • the temperature of the soap is made uniform and directional qualities are given to the pearl gloss material in the soap, and thereafter the soap thus treated is flowed out from nozzle 15 provided at the end of the means 12.
  • This flowing soap is poured into a solidifying container to provide the soap having pearl gloss design in a continuous manner.
  • the solidified soap is removed from the solidifying container and cut, dried and stamped to provide a commercial product.
  • EXAMPLE A soap glue obtained by sponifying a mixed fat composed of 70 parts of beef tallow and parts of coconut oil with an aqueous solution of 30% sodium hydroxide under heating is added to tank 1, and 55 parts of alcohol, 5 parts of water and 30 parts of sucrose are further added thereto. Then, the mixture is dissolved under stirring by means of the stirrer 2 to give warm-fused transparent soap material. Then, 2 to 4 parts of 20% fish scale paste dispersed in alcohol is added to said soap material to disperse therein. Thereafter the soap material thus produced is supplied into the cooling means 7 through the pipe 3, the pump 4 and the pipe 5. In the cooling means 7 said material is cooled under stirring to a liquid-solid transition temperature region of 46511" C.
  • the soap material kept at said temperature region is delivered into the means 12 to give directional qualities, whereafter the soap so treated is poured into a solidifying container through the nozzle 15. After cooling solidification, the solidified soap is withdrawn from the solidifying container and cut, dried and stamped to provide a soap product having gloss design.
  • the method according to the present invention is very efficient and extremely suitable for continuous industrial manufacturing due to the fact that same can be carried out without any cooling operation under stirring in separate solidifying containers.
  • a process for continuously producing soap having pearl gloss comprising the steps of:
