摘要： The present disclosure relates to a method for preparing liquid maltitol and liquid polyols from a raffinate including maltitol. The method comprises the following steps: obtaining a hydrogenated liquid by hydrogenating a pre-treated raffinate including maltitol, obtaining a post-treated liquid by post-treatment of the hydrogenated liquid to remove impurities, obtaining a dilute liquid and a concentrated maltitol solution by membrane-separation of the post-treated liquid, and using the dilute liquid as the liquid polyols, and obtaining the liquid maltitol by mixing the concentrated maltitol solution with a prepared maltitol solution with a maltitol content of over 50%, wherein the liquid maltitol has a maltitol content greater than or equal to 50% and meets a standard. Before the membrane separation process, the present disclosure reduces the reducing sugar content in the liquid by hydrogenation to lower the risk of yellowing during the process and to improve the quality of the final product.

摘要： The present disclosure provides a preparation system and a preparation method for xylitol crystals. In the preparation system, outlets of a first centrifuge are connected with an inlet of a hot air drying tank and an inlet of a primary mother liquor storage tank through pipelines, respectively. Outlets of a second centrifuge are connected with an inlet of a second fluidized bed dryer and an inlet of a secondary mother liquor storage tank through pipelines, respectively. An outlet of a dicrystalline sugar dissolution tank is connected with an inlet of a blending tank through pipeline. An outlet of a tricrystalline sugar dissolution tank is connected with the inlet of the primary mother liquor storage tank. The blending tank is provided with an inlet for a raw material of xylitol hydrogenation solution. An output of an outlet of a first fluidized bed dryer is prepared xylitol crystals.
