Abstract

This paper describes a gas recirculation system for the exhaust gases from the aerobic fermenters normally used in acetic fermentation processes. With the application of this procedure, it is possible to operate in a closed system, so preventing the large losses of fermentation yield due to evaporation which occur in open systems. In addition, this system reduces losses of volatile organoleptic compounds (ethanol, acetic acid and ethyl acetate, among others) so enabling the product to be incorporated into processes for the manufacture of high quality vinegars.
