摘要： The present disclosure relates to a preparation system and a preparation method for high-quality xylitol crystals. The preparation system comprises a blending tank, a heat exchanger, a decolorization tank, an ion exchange system, a micropore filter, a first evaporator, a first crystallization kettle, a first centrifuge, a fluidization drying bed, a xylitol dissolution tank, a second evaporator, a second crystallization kettle, a second centrifuge, a hot air drying tank, and a cold air fluidization bed which are sequentially connected through pipelines. The first centrifuge is also connected with the blending tank through a pipeline. The second centrifuge is also connected with the xylitol dissolution tank through a pipeline. The blending tank is provided with an inlet for a xylitol hydrogenation solution. The xylitol dissolution tank is provided with a water inlet for purified water. A material output from the cold air fluidization bed is a xylitol crystal product. The first prepared xylitol crystals are dissolved by adding water in a certain proportion to obtain a xylitol solution with a higher purity, which is recrystallized to prepare xylitol crystals with higher pH and better flavor.

摘要： The present disclosure discloses a system for co-producing a xylitol and a caramel pigment by utilizing a xylose mother liquid. The system includes a raw material tank, a filter, a nanofiltration membrane device, a first ion exchange device, a chromatographic separation device, a refined hydrogenation assembly, and a browning reaction assembly that are sequentially connected through a pipeline. The chromatographic separation device is configured to obtain an extracted liquid and a raffinate liquid by separating the xylose mother liquid that flows through the chromatographic separation device. The refined hydrogenation assembly is configured to prepare a crystal xylitol by performing a refined hydrogenation processing on the extracted liquid. The browning reaction assembly is configured to prepare the caramel pigment by performing a browning reaction processing on the raffinate liquid. The present disclosure also discloses a method for co-producing a xylitol and a caramel pigment by utilizing a xylose mother liquid. The present disclosure prepares the crystal xylitol by purifying and crystallizing the xylose mother liquid and preparing the caramel pigment through the raffinate liquid obtained after a chromatographic separation, which improves the value of the xylose mother liquid.
