After process of few hours, neat soap will be ready in saponification vessel which is transferred in to cooling moulds. After cooling and drying of the same soap for few hours, the same soap is converted in soap chips by using soap chips making machine that is for fast and better drying. The dried chips are used for finishing of soap and that process is started from soap mixer machine where desired color and perfume can be added if required.
