of conventional soap products.
Patented Jana l, 194% METHOD AND APPARATUS FOR TREATING SOAP PRODUCTS Thomas Penny, Brimstage, Bebington, England,
assignor to Lever Brothers Company, bridge, Mass, a corporation of Maine Cam- Application April 2, 1941, Serial No. 386,476 In Great Britain April 16, 1940 2? Claims.
The present invention relates to the improvement of the external appearance and characteristics of soap products by imparting thereto a more polished or glossy surface.
It long has been appreciated by soapmalrers that more polished or glossy soap products are received with greater favor by the every-day user For example, it is well established that the improved external appearance of milled soap, as compared with ordinary framed soap, is one of the preferred characteristics of this type of product.
Many methods have been devised, heretofore,
for improving the gloss or appearance of conventional soap products, for example, by incorporating in the soap small quantities of sugar, glycerin,
' mineral oil or other substances. In some instances, the manufacturers have resorted to burrushing processes utilizing alcohols and other If desned, my invention may be utilized in place or or to supplement soap polishing processes which are used in conventional operations. 0n the other hand, in view of its economical nature, the process may be applied to conventional soap products which ordinarily are not subjected to treatment for improving their surface appeen auce, i
My process may be operated continuously, if desired, and may be integrated without dificulty with any conventional soap making processes. For example, it generally is desirable to carry out my process atthe end of the usual soap finishing processes and just prior to the packaging or wrapping of the soap articles.
. It is an advantage of my invention, however, that immediate wrapping of the soap after the polishing treatment is permitted, whereby the operating time of the soap maliing process is not materially increased. Moreover, the improved external appearance and characteristics of the treated soap products are not damaged or deleteriously afiected by conventional soap wrapping processes, or by the wreppings themselves.
The process of my invention in general comprises a superficial treatment of soap products with steam, followed by drying and cooling, whereby the surface of the soap undergoes a smoothing or refining which gives the soap 3 desired polished or glossy appearance. 7 My invention also resides in novel apparatus for efiecting a steam treatment and drying of conventional soap products for carrying out the process more fully described hereinafter.
Myinvention willbe described more part cularly in connection with the drawing, in which: Fig, l is a diagrammatic view of apparatus which may be used for treating soap cakes or bars in accordance with my invention;
Fig. 2 is an enlarged view of the steaming elements utilized in the apparatusshown in Fig 1. In the preferred mode of carrying out my invention, a soa product such as soap cakes may be caused to pass between opposing flows of hot steam, such as may be provided by steam jets in such a fashion that the steam contacts substantially the entire surface of the soap particle for a short period of time. In the case of soap cakes or bars, for example, this may be accomplished by spacing the soap from the upper surface of a carrier and causing the soap to be moved thereby through a chamber wherein jets of steam are directed against substantially all of the surface of the soap. In the case of soap flakes or chips, the soap may be permitted to iallloetween oppositely directed flows of steam, whereby both sides of the chips or flakes may be treated. After the steaming operation, it, is desirable to dry the sur face of the soap without material delay. This may be accomplished, for example, by passing the soap through a zone of drying air which, ii desired, may be heated for more effective drying. ii heated air is used, it is desirable to cool the soap after drying by means of a, flow of cool air or by permitting the soap to cool naturally prior to wrapping or packaging.
Referring to Figs. land 2, conventional soap bars or cakes it may be placed upon triangularly arranged pins ll disposed on a plurality of small 1 platforms 52. This form of supporting means provides a minimum contact of the soap with the supporting means and permits the steam or air in the treating chambers, to be described more particularly hereinafter, to have free and equal access to all sides of the cake or bar. The soap bars or cakes ordinarily will be treated after the usual stamping operation. lhis order is not essential, but may be preferred because in some instances it will be found that a subsequent stamping operation will impair the gloss of the bars or cakes which have been polished'in accordance with my invention. The platforms l2 carrying the soap bars or cakes I I thereupon may be placed upon an endless band IS in sequence, .or these platforms may be secured permanently upon the band l3 as more convenient. The platforms carrying the soap cakes are conducted by the endless band through a steaming chamber ll which is provided her, for example, by means of conduits it pro-' vided with a steam trap l9 to remove any droplets of water. v
After the platforms carrying the soap have passed through the steaming chamber M, they may be conducted through an elongated drying chamber 20 which is provided with an air tunnel 2| for introducing-a flow of drying air therethrough. If desired, a bame 22 may be placed adjacent the entrance of the drying chamber for preventing air from being directed against and entering the steaming chamber 14. The air tunshown in the drawing, whichever may be the time required to obtain desired results may be readily determined, and will depend'upon the factors of operation, such as the temperature and rate of flow of the steam utilized;
It generally is more desirable to. pass the soap product successively through the'steaming and drying operations with the shortest practical interval of time between the two operations.
It heated air is utilizedfor drying the soap. it I may be preferred to utilize a temperature, for
example, of the order of 130 to 150 C. The temperature may be varied, as desired, to eiiect the requisite drying rate. After drying with heated air, it is preferred subsequently to treat the soap with cool air to completely solidify and retain the resulting gloss on the surface .of the nel 2| may be provided at itsouter end with a fan 23 for supplying air thereto. I If it is desired to utilize heated air, a. heating element such as a resistance heater 24 may be placed, for example, within the air tunnel where it will come in contact with the air being supplied by the fan 23.
In carrying out my invention, I prefer to utilize a steam pressure or quantity of steam just sulficient to cause the steam to emerge gently from the steam jets. .This ordinarily provides a sufilsient steamingaction to bring about the desired surface modification of the soap products. It will be apparent to one skilled in the art, however, that-this rate of flow is not critical and may be varied depending upon the extent ofv the surface modification desired, the emciency of the steaming apparatus, the character of the soap product 1 being treated, and other variables.
The temperature of the steam at the place of contact with the soap products also may be varied over a wide range. In general, a temperature in the neighborhood of 90 to 100 C. will produce desired results.- Other temperatures may be utilized depending, for example, upon the characteristics of the soap being treated or upon the length of time during which the soap i in contact with the steam. I have found that wet or dry steam, or steam mixed with air, may be employed in the steaming zone. In general, it is desirable to avoid the product although in many instances, normal cooling will suiilce. V of time is required for drying the soap than is required during the steaming operation. For example, in treating conventional soap cakes or bars, the steaming operation may require only one second, whereas the drying operation may require a period of about twenwj-five seconds.
After the soap has been dried and cooled, as described above, the surface of the soap shows a high gloss or polish which greatly enhances the appearance, of the soap product. The soap,
thereupon may be wrapped or packaged in aconventional manner, without any material damage to the polished surface during such operation, or by the wrappers or packages themselves.
It will be apparent that my invention will be I susceptible to modifications by one skilled in the art without departing from the scope thereof,
and all such modifications areintended to be included within the scope of the following claims.
I claim:
