This utility model patent discloses a production line suitable for polyol production, including a reaction vessel for adding raw materials, a centrifuge connected to the reaction vessel, and a finished product tank and a waste residue tank connected to the material outlet and waste outlet of the centrifuge. A disperser is also installed between the centrifuge and the reaction vessel, with its inlet connected to the waste outlet of the centrifuge and its outlet connected to the inlet of the centrifuge. In this utility model patent, the disperser between the centrifuge and the reaction vessel disperses and stirs the waste residue discharged from the centrifuge, then feeds it back into the centrifuge for recycling. This not only increases product yield and reduces waste residue output, lowering production costs, but also solves the problem of difficult waste residue disposal in traditional production lines, meeting environmental protection requirements.
