PURPOSE: A manufacturing apparatus of expanded polystyrene or expanded polypropylene is provided to be able to maximize the energy efficiency by recycling the waste steam discarded in the heating process for molding the expanded polystyrene or expanded polypropylene as a heating source of the drying process. CONSTITUTION: A manufacturing apparatus (100) of expanded polystyrene or expanded polypropylene comprises a molder (120) molding expanded polystyrene or expanded polypropylene by using the supplied steam; a waste steam collector (200) collecting the waste steam (S) emitted from the molder in a recyclable form; and a dry process part (300) drying the molded expanded polystyrene or expanded polypropylene by recycling the collected waste steam separately or along with the supplied steam as a heating source. |
