The invention discloses a method for preparing xylo-oligosaccharides from corn husks. The raw material is corn husks, firstly adding acetic acid and water, stirring and mixing to form a suspension, the pH value is adjusted to 4.5-5.5, and then pumped into a booster ejector, and then After passing through the laminar flow tank, the pressure is quickly released by the gas-liquid separator, and the secondary steam is recovered for the subsequent heating of the material. The liquid enters the saccharification tank, and then adds xylanase and saccharification enzyme after cooling down. >=3%, low conductivity (<3000μs/cm), solid content of 3-5%, xylo-oligosaccharide purity >70%, product quality is improved, sewage volume is greatly reduced, and waste heat from vapor-liquid separation is easy to recover , the energy consumption is reduced. |
