Abstract
The present disclosure provides a system and method for a refinement processing of xylitol fermentation broth. The system includes a fermentation component, a filtration and impurity removal component, and a refinement component. The fermentation component is configured to perform a fermentation processing on a raw material containing xylitol to obtain sediments and supernatant fermentation broth. The filtration and impurity removal component includes a ceramic membrane filter, a nanofiltration membrane filter, an activated carbon filter, and ion exchange columns. The ceramic membrane filter is configured to filter the supernatant fermentation broth to obtain ceramic membrane discharge liquid. The nanofiltration membrane filter is configured to perform a nanofiltration membrane filtration processing on the ceramic membrane discharge liquid to obtain nanofiltration liquid. The activated carbon filter is configured to perform an activated carbon filtration processing on the nanofiltration liquid to obtain activated carbon discharge liquid. The ion exchange columns are configured to perform an ion exchange processing on the activated carbon discharge liquid to obtain xylitol ion exchange liquid. The refinement component is configured to perform the refinement processing on the xylitol ion exchange liquid to obtain a xylitol crystal product.
