The use of dry soap noodles, especially if they include many dry specks, could required a pre-refining of noodles before the mixer. This operation can be done installing a simplex refiner plodder or a roll mill before the mixer. In this way the external dry part of the noodles is broken and the soap can absorb better the soap additives.
To avoid a cost of a simplex refiner plodder or a roll mill, a pelletizer can be used. A Pelletizer is similar to a simplex refiner plodder, but it assembled a short screw and a smaller motor size; moreover a soap pelletizer does not assemble any refining screen.
