<;P>;PROBLEM TO BE SOLVED: To provide a technology that fundamentally reconsiders an ethanol production system by a conventional process (liquid fermentation process), in which the difficulties in treatment and disposal of distillery effluent in efficiently using surplus rice are big problems, and which suppresses discharging of distillery effluent, as much as possible. <;P>;SOLUTION: The method for treatment of rice includes processes of saccharification for saccharifying raw material rice to prepare a saccharified solution, fermentation of solids for adjusting the water content of fermentation broth, consisting of the saccharified solution, yeast and water, at the start of fermentation to 50-60 wt.% and carrying out solid fermentation and distillation process for distilling the ethanol obtained. <;P>;COPYRIGHT: (C)2009,JPO&INPIT
