The utility model relates to an ethanol production device, and particularly relates to an ethanol fermentation liquid grain stillage separating and drying device. The device is characterized in that a pressure filter is arranged at the upper part of the device; the ethanol fermentation mash is input, and the material flows from top to bottom; the material at a bottom outlet of a pressure-filtered clear liquid storage tank is fed into a rectifying unit; the dry grain stillage is output through a 4# closed spiral conveyor; and the dried finished product of grain stillage is conveyed to a storehouse. The device provided by the utility model has the beneficial effects that (1) the device separates the grain stillage of the fermentation liquid, solves the problem in sewage treatment of an ethanol enterprise, realizes complete recycling and crushing and mixing of residual water at the bottom of a clear liquid ethanol distillation and coarse distillation tower so as to fully utilize active ingredients in the residua
