NOVELTY - The process comprises sampling a part of wort from the fermenter during fermentation, separating a biomass (4), which is recycled to the fermenter, flash evaporating the separated liquid and obtaining the organic products in gaseous phase, and isolating the organic products. The separation of biomass is carried out by filtration, ultrafiltration, decantation, centrifugation and/or ultracentrifugation, and the separation of biomass in a liquid gas separator (5) is useful for performing flash evaporation, which is carried out at a pressure of 10-200 mbar and a temperature of 10-40 degrees C.    USE - The process is useful for continuously separating organic products such as biobutanol from fermentation of sugar cane molasses in a fermenter (claimed).    ADVANTAGE - The process is capable of continuously, effectively and easily separating the organic products from fermentation of sugar cane molasses in the fermenter with improved performance, reliability and yield.    DETAILED DESCRIPTION - The process comprises sampling a part of wort from the fermenter during fermentation, separating a biomass (4), which is recycled to the fermenter, flash evaporating the separated liquid and obtaining the organic products in gaseous phase, and isolating the organic products. The separation of biomass is carried out by filtration, ultrafiltration, decantation, centrifugation and/or ultracentrifugation, and the separation of biomass in a liquid gas separator (5) is useful for performing flash evaporation, which is carried out at a pressure of 10-200 mbar, a temperature of 10-40 degrees C and an evaporation rate of 1-70 mass%. The separation during the flash evaporation is carried out without the addition of solvent. A temperature of an aqueous phase is lower than a temperature of the fermenter, where the aqueous phase is recycled to the fermenter. The water of the gaseous phase obtained from the flash separation is condensed and recycled to the fermenter. An INDEPENDENT CLAIM is included for a device for continuously separating organic products from fermentation in a fermenter.
