Abstract: The present invention relates to a system for jointly producing erythritol and liquid sorbitol by using a corn starch, including a liquefaction tank, a saccharification tank, a filter and a nanofiltration assembly. The liquefaction tank is used to perform liquefaction for the corn starch, the saccharification tank is used to perform saccharification for the liquefied material, the filter is used to filter out impurities in the saccharified material to obtain a glucose liquid, and the nanofiltration assembly is used to perform nanofiltration for the filtered glucose liquid to respectively obtain a dialysate and a concentrate. The system further includes a fermentation and crystallization assembly for performing fermentation and crystallization for the dialysate to prepare crystalline erythritol, and a hydrogenation and evaporation assembly for performing hydrogenation and evaporation for the concentrate to prepare liquid sorbitol.

Abstract: A system and method for producing cellulosic ethanol by biomass saccharification and fermentation is provided. The system includes a first reactor configured to carry out an enzymatic hydrolysis reaction of a biomass feedstock, a second reactor configured to carry out a fermentation reaction of the biomass feedstock, and a collection tank configured to collect the cellulosic ethanol. The first reactor and second reactor are provided with an enzymatic hydrolysis dosing pipe and a fermentation dosing pipe, respectively. An outlet of the first reactor is connected to an inlet of the second reactor through a fermentation pipe. An outlet of the second reactor is connected to an inlet of the first reactor through a discharge pipe that is provided with a first discharge pipe configured to discharge material from the second reactor. The first reactor is connected to an inlet of the collection tank through an ethanol pipe.
