PROCEDIMIENTO E INSTALACION DE FERMENTACION Y UTILIZACIONES QUE SE REFIEREN.

摘要

In the fermentation process, the vapors emitted from the fermentation vat, resulting from fermentation and entrained by the CO2, are subjected to condensation. This condensation is effectuated fractionally in at least two successive stages (5, 7) operating at temperatures of about -5 DEG C. to -15 DEG C. in the first stage and -15 DEG C. to -50 DEG C. in the second stage. The process is effective to improve the quality and/or the quantity of fermentation product, in particular of wine in the case of grapes fermentation.
