Abstract

La présente invention concerne un procédé de conservation active d'une culture de levure ainsi qu'un dispositif servant à son exécution. Suivant l'invention, on utilise une levure floculante qui après fermentation dans une installation de sédimentation est au moins partiellement séparée du moût Une partie de la levure est recyclée; l'autre est récoltée. Le dispositif comprend un étage de fermentation 1 et une installation de sédimentation 2 prévue en aval, dont part une conduite 3 pour le recyclage de la levure dans ledit étage de fermentation. L'invention s'applique à la fermentation alcoolique de la mélasse pour devenir de l'alcool éthylique.The present invention relates to a method for actively preserving a yeast culture as well as a device for carrying it out. According to the invention, a flocculating yeast is used which, after fermentation in a sedimentation installation, is at least partially separated from the must. Part of the yeast is recycled; the other is harvested. The device comprises a fermentation stage 1 and a sedimentation installation 2 provided downstream, from which starts a pipe 3 for recycling the yeast in said fermentation stage. The invention applies to the alcoholic fermentation of molasses to become ethyl alcohol.
