Abstract:
1. An improved ethanol production process comprising: (a) milling a carbohydrate-containing material to produce a carbohydrate-containing flour having a median particle size of less than about 100 microns; (b) hydrolyzing the carbohydrate-containing flour under operating conditions to form a mixture comprising partially gelatinized carbohydrate-containing flour and cleaved terminal amylose groups, wherein the terminal amylose groups are cleaved from the carbohydrate-containing flour; (c) milling soy hulls to produce a soy hull flour having a median particle size of less than about 100 microns; (d) adding the soy hull flour to the mixture to form a slurry, the slurry comprising the partially gelatinized carbohydrate-containing flour, the cleaved terminal amylose groups, and the soy hull flour; (e) fermenting the slurry to produce fermented slurry, the fermented slurry comprising ethanol and whole stillage; and (f) distilling the fermented slurry to separate the ethanol from the whole stillage.
