PROBLEM TO BE SOLVED: To provide a method for producing a solid soap containing bubbles by which the change in product mass is reduced by controlling the density of a liquid soap to be inserted into a molding mold.SOLUTION: The method for producing the solid soap containing bubbles by using a production apparatus equipped with a formulating vessel of the liquid soap, a foaming machine, a feed vessel, an injection part and a feed-stabilizing vessel, and having a circulating line formed by connecting the feed vessel, the injection part and the feed-stabilizing vessel with circulating pipe lines, and a circulating pump installed in the circulating pipe line downstream of a feeding position to the injection part includes foaming the liquid soap fed from the formulating vessel by the foaming machine, once storing the foamed liquid soap in the feed vessel, and filling the molding mold with the foamed liquid soap through the injection part by regulating the density of the liquid soap by the speed control of the circulating pump while circulating the foamed liquid soap in the circulating line. |
