A new method of producing bio-energy by using sugar-beets

Abstract

A patented technology of ethanol production by sugar-beets is introduced in this paper. After squeezing the juice of sugar-beets, by multi-effect evaporation, high sugar solution could be acquired and infection microbes could be killed at the same time; recycling impregnating sugar-beets and adjust sugar concentration to 26% by waste from distillation to improve the efficiency of fermentation and distillation. Raw material prices and evaporation energy are the main economical influencing factors to the new technology. Compared with the traditional production methods, patented technology can generate significant economic benefits. © 2011 Published by Elsevier Ltd.
