TWO- PRODUCT ALCOHOL OBTAINING TECHNOLOGY BASED ON CONTINUOUS GRADIENT YEAST GENERATING

The work objective was to use a serial connection of yeast generators (according to the battery principle) and by means of this to increase the rate of medium dilution therein from 0.18?0.20 to 0.88?0.96 h-1, to reduce the solids concentration in the yeast mash from 17 to 10?12% and to enter the whole volume of it into the first streamwise device. The amount of molasses that has not been added to the mash in order to solids concentration reduction in it was introduced into the last two yeast generators. Consequently, it has been clearly shown the intensification of biomass accumulation, its yield increase by 29% with regard to ethanol amount and increase in productivity of yeast culturing by 18%.
