1. A system for jointly producing erythritol and liquid sorbitol by using a corn starch, comprising a liquefaction tank, a saccharification tank, a filter, a nanofiltration assembly, a fermentation and crystallization assembly, and a hydrogenation and evaporation assembly;
wherein
the liquefaction tank is configured to perform liquefaction for the corn starch to obtain a liquefied material,
the saccharification tank is configured to perform saccharification for the liquefied material to obtain a saccharified material,
the filter is configured to filter out impurities in the saccharified material to obtain a glucose liquid,
the nanofiltration assembly is configured to perform nanofiltration for the glucose liquid to respectively obtain a dialysate and a concentrate,
the fermentation and crystallization assembly is configured to perform fermentation and crystallization for the dialysate to prepare crystalline erythritol, and
the hydrogenation and evaporation assembly is configured to perform hydrogenation and evaporation for the concentrate to prepare liquid sorbitol.
