キシロース加水分解液の脱色ろ過装置及びその脱色ろ過方法

Japanese Patent JP7147081

B2

The present invention discloses a xylose hydrolysate decolorization and filtration device. A hydrolysate is filtered through a to-be-cleaned filtering machine to form a waste carbon liquid with a light transmittance of 7% to 10%, the waste carbon liquid is subjected to pressure filtration through a filter press to form a plate and frame liquid, the plate and frame liquid is filtered through a to-be-passed-through filtering machine to form a pre-decolorized liquid with a light transmittance of 30% to 35%, the pre-decolorized liquid enters a decolorization tank and is mixed with added new carbon in the decolorization tank to form a new carbon liquid, and the new carbon liquid is filtered through a standby filtering machine to form a decolorized liquid with a light transmittance of greater than 65%. The present invention further discloses a xylose hydrolysate decolorization and filtration method using the device. According to the present invention, the pollution of carbon powder to the surrounding environment is effectively reduced, the xylose hydrolysate is effectively decolorized and filtered, the device is designed in a compact way and takes up less space, and the entire decolorization and filtration process is carried out in a sealed environment, which reduces the pollution to the surrounding environment.
