Effect of corn preparation methods on dry-grind .Traduire cette page

01/06/2011 · In some dry-grind ethanol process, a portion of thin stillage is returned to fermentation vessel, termed 'backset', to conserve on water and provide nutrients to yeast; ethanol yield is affected by amount of backset applied, among other parameters (Soto et al., 2005).The nutrient and solids content of thin stillage, which affects its utilization, is affected in turn by the particle size of ...

Keywords: Dry-grind, Ethanol, Particle Size, Thin Stillage The effect of corn flour particle size on ethanol yields and soluble solids in thin stillage in a dry-grind process were studied. Predictably, in a conventional dry grind process, ethanol yields increased approximately by 102% as particle size varied from 1.077 mm to 0.568 mm (mean geometric diameter).
