Abstract

In a production of ethanol in plants, comprising a fermenter, a centrifugal separator for the recirculation of the yeast to the fermenter and a plant for the separation of a yeastfree flow, coming from the centrifugal separator, into one flow, rich in ethanol, and into one residual flow, the substrate, that is fed to the fermenter must be rid of solid substance, like fibres etc. In the separation of such solid substance a certain amount of substrate has been lost according to the methods utilized hitherto, or an unnecessarily high consumption of water and energy has occurred. According to the invention the solid substance, which is separated from the raw material flow, is washed, preferably countercurrently with said residual. flow, which in turn, enriched in substrate, is fed to the fermenter. If a distillative method is used for said separation the residual flow is called slop.
