Improvements in the Manufacture of Soap, A communication by Anatole Des Cressonnieres and . Ernest Des Cressonnieres, botli of 82, Chaussee de Gand, Brussels, in the Kingdom of Belgium, Soap Makers. I, W illiam Phillips Thompson, F.C.S., M.I.M.E., of the Agency for Foreign Patent Solicitors, G, Lord Street, Liverpool, and G, Bank Street, Manchester, both in the County of Lancaster, 118, New Street, Birmingham, in the County of Warwick, and 322, High Holborn, in the County of Middlesex, Civil Engineer, b do hereby declare the nature of this invention to be as follows: — sJ This invention relates to an improvement in the manufacture of soap. The improvement in the manufacture of soap in question consists essentially in the intermingling of the material during drying, that is to say, an additional working or trituration of the paste, having the effect of changing or renewing 10 the surfaces, or in other words, of turning to the outside the layers hitherto inside the sheets, flakes, shavings or other divided forms in which the paste is exposed to drying, so that the drying proceeds more uniformly over all the parts (f the paste, in contradistinction to that which occurs in the ordinary process in which the drying action is invariably exercised uj on the outer layer alone during Id the whole period of the drying. In older to obtain the requisite degree of de-hydration in relation to the total quantity of the product, its exposure in the drying apparatus must be of a corre¬ sponding duration. Now as in the ordinary process the drying action proceeds continuously upon the same external layer, this layer soon becomes a hard and 20 impermeable crust opposing the normal action and retarding the result, and consequently prolonging the period of time required for the drying, and requiring an increased amount of heat, and which above all has the drawback of destroying the homogeneousness of the material or mass which is thus dried irregularly throughout its various layers, and which consequently affects the quality of the 25 paste in a manner hardly to be afterwards remedied. The process of the intermingling of the paste in the course of drying entirely obviates these various inconveniences, that is to say, the material dries uniformly without forming any crust, the period of drying is shortened, heat is economised, and above all the quality of the paste is superior, and it requires no subsequent 30 improvement. It must be understood that the new process is applicable to all systems of manu¬ facture and of drying, because its effect will always be proportional to the \JPrice 8'/.]
