Pulverizing/kneading apparatus and method for manufacturing soap using the pulverizing/kneading apparatus
 A pulverizing/kneading apparatus for pulverizing and kneading a material such as a soap compound. The material is supplied in a barrel in which are provided a pair of shafts respectively having feeding helical gears and returning helical gears. The material supplied is kneaded and the fine particles contained in the material pulverized by the gears. The forward driving force of the feeding gears is larger than the backward driving force of the returning gears so that the material advances forwardly toward the discharge opening of the barrel.
