ABSTRACT In a process for the production of ethanol through conti- nuous fermentation of a carbohydrate containing substrate which contains fermentable substance as well as non-ferment- able soluble and solid substance, the substrate is hydrolyzed in a hydrolysis step and fermented in a fermentor comprised in a continuous process circuit comprising the fermentor , a yeast separation step and a distillation step . From the fermentor a stream of fermentation liquor is continuously withdrawn, and is then separated into a stream enriched in solid substance, which is discharged from said process circuit, and a stream impoverished in solid substance, which is fed to said yeast separation step . From the yeast separation step a yeast concentrate stream is recirculated to the fermentor and the yeast- free stream is sent to the distillation step , wherein ethanol is distilled off and a remaining stillage stream is obtained, part of which is continuously recirculated to the fermentor or to the hydrolysis step .
