Abstract

The invention relates to a device for producing ethanol, wherein the mash is supplied to a distillation column. The invention is characterized in that the distillate (28) of the one distillation column (27) is supplied to at least two filter devices (30, 31) that interact in a cascade (29), the permeates (32, 33) of the filter devices (30, 31) being reintroduced into the distillation column (27) and the retentate (35) of the last filter device (31) being removed as the final product ethanol.
