주정발효공정에서 생성되는 불순물의 분리를 위한 공정개선으로 주정원료별 불순물의 양을 알아보고 이를 super-allospas식 연속증류기에서 집적하여 효율적인 분리를 하였다. 주정발효공정중에 생성되는 불순물 중 methanol은 절간고구마가 가장 많이 생성되었고 그 다음이 타피오카였다. fusel oil중 n-propanol은 쌀, 절간고구마, 옥수수, 쌀보리 및 타피오카의 순서이고 iso-butanol은 타피오카, 옥수수, 쌀, 절간고구마 및 쌀보리의 순서였다. 그리고 iso-amyl alcohol은 타피오카, 쌀. 절간고구마 옥수수, 쌀보리의 순이었다. 한편 supper-allospas식 연속증류기에 의한 fusel oil의 분리시 alcohol함량에 따른 집적율을 보면 n-propanol은 alcohol이 78.25%(v/v)일 때 37.9%. iso-butanol은 alcohol이 68.54% (v/v)일 때 28.6%, n-butanol은 alcohol 50% (v/v)일 때 37.4% iso-amyl alcohol은 alcohol이 50% (v/v)일 때 56.1%의 가장 높은 집적율을 나타내었다. 이와 같이 집적된 불순물은 side cut 하여 후류탑으로 유입시킨 후 재차 농축하여 탑저부의 붕(plate)에서 fusel oil을 side cut하여 일부는 직접분리하고 나머지는 다시 fusel oil분리기에 넣어 alcohol이 20%(v/v) 되도록 가수하여 분리하였다.

This study to elucidate concentrations of impurities such as methanol and fusel oil formed during fermentation process among the different materials and has been applied technical seperation for processing improvement by continuous distillation of super-allospas type. Methanol was formed high concentrations of cutting dried sweet potato and tapioca in order among the different materials during fermentation process. n-Propanol oil was formed high concentration of rice, cutting dried sweet potato, corn, naked barley and tapioca in order among the those materials. I-Buthanol showed high concentration of tapioca, corn, rice, cutting dried sweet potato and naked barley in order and isoamyl-alcohol showed high concentration of tapioca, rice, cutting dried sweet potato, corn and naked barley in order. Using the continuous distillation of super-allospas type, the following are collection ratios of n-propanol, iso-butanol, n-butanol and iso-amylalcohol: 37.9%, 28.6%, 37.4%, and 56.1% when 78.25% (v/v), 68.54% (viv), 50.0% (viv), and 50.0% (v/v) alcohol are used, respectively. Fusel oil and bad alcohol put into the recovery column and then seperated directly by side cut of fusel oil partially from plate of tower bottom after concentration again. Extra impurities seperated by fusel oil seperator when 20 % (v/v) alcohol adjusted with water.
