Abstract

PROCEDE DE PRODUCTION D'ETHANOL DANS UNE INSTALLATION COMPRENANT UN APPAREIL DE FERMENTATION 1, UN SEPARATEUR CENTRIFUGE 2 DE RECYCLAGE DE LA LEVURE A L'APPAREIL DE FERMENTATION ET UN APPAREIL 3 D'EXTRACTION D'UN ECOULEMENT EPUISE EN LEVURE PROVENANT DU SEPARATEUR CENTRIFUGE EN UN ECOULEMENT RICHE EN ETHANOL ET UN ECOULEMENT RESIDUEL. LA SUBSTANCE SOLIDE EST PRELEVEE DE L'ECOULEMENT DE MATIERES PREMIERES ET LAVEE, AVANTAGEUSEMENT, A CONTRE-COURANT AVEC L'ECOULEMENT RESIDUEL QUI S'ENRICHIT EN SUBSTRAT ET EST AMENE A L'APPAREIL DE FERMENTATION 1.
