| abstract |
The disclosed ethanol manufacturing device (1) is provided with a solid-liquid separation means (2), a distillation means (3), a drying means (4), and a vapor-supply means (5). The solid-liquid separation means (2) separates a fermented substance (60), which has undergone ethanol fermentation, into an ethanol-containing filtrate (61) and a filter cake (62). The distillation means (3) concentrates the ethanol-containing filtrate (61) via distillation, yielding ethanol (6). The drying means (4) dries the filter cake. The vapor-supply means (5) supplies, to the distillation means (3), an ethanol-containing vapor (63) generated by the drying performed by the drying means (4). Also disclosed is a method for manufacturing ethanol by performing a solid-liquid separation step, a drying step, and a distillation step. |
