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. The present invention further provides a method of jointly producing erythritol and liquid sorbitol by using a corn starch. The present invention not only improves the purity of erythritol but also obtains liquid sorbitol, thus improving the utilization value of the corn starch.

The present invention provides a method of improving a biomass high-solid enzymatic hydrolysis rate. By screening particle sizes of the biomass substrate, different water content controls are performed on coarse and fine particle biomass substrates and then an entire water content of the mixture of the coarse and fine particle biomass substrates is controlled to achieve a reduced initial viscosity of the enzymatic hydrolysis and improve liquefaction speed, and finally improve the biomass high-solid enzymatic hydrolysis rate. The enzymatic hydrolysis system of the present invention can be easily constructed with lower equipment requirements, lower energy consumption, higher enzymatic hydrolysis efficiency and simpler operation process, helping the industrial production and applications.
