PRESACCHARIFICATION TREATMENT DEVICE FOR LIGNOCELLULOSIC BIOMASS
First Claim
1. A presaccharification treatment device for lignocellulosic biomass comprising:
- a treatment unit configured to mix lignocellulosic biomass as a substrate and ammonia water, and then treat the yielded substrate mixture in a wet powder state to dissociate lignin contained in the substrate or to swell the substrate to yield a presaccharification treatment product in a wet powder state; and
an ammonia separation unit configured to separate ammonia from the presaccharification treatment product;
wherein the treatment unit comprises;
a treatment vessel;
a substrate supply unit configured to supply continuously the substrate to the treatment vessel;
an ammonia water supply unit configured to supply continuously the ammonia water to the treatment vessel;
a mixing unit configured to agitate the substrate and the ammonia water supplied to the treatment vessel to thereby apply shearing force and impact force to the substrate and to mix the ammonia water and the substrate to yield the substrate mixture; and
a storage unit placed directly beneath the treatment vessel communicating with the treatment vessel and configured to store a substrate mixture supplied from the treatment vessel for a predetermined time period and to dissociate lignin contained in the substrate or to swell the substrate during storage without heating to yield a presaccharification treatment product; and
wherein the ammonia separation unit comprises a presaccharification treatment product supply unit placed beneath the storage unit and configured to supply continuously the presaccharification treatment product from the storage unit to the ammonia separation unit, and is located directly beneath the storage unit.

Abstract
[Problems to be Solved] Provided is a presaccharification treatment device, which can yield from lignocellulosic biomass as a substrate a presaccharification treatment product without heating and thereby at a reduced cost.
[Solution] A presaccharification treatment device (1) comprises a treatment unit (2), which mixes lignocellulosic biomass and ammonia water and treats a yielded substrate mixture in a wet powder state for yielding a presaccharification treatment product, and an ammonia separation unit (3), which separates ammonia from the presaccharification treatment product. The treatment unit (2) comprises a treatment vessel (21) and a storage unit (25), in which a presaccharification treatment product is yielded during retention therein for a predetermined time period from the substrate mixture without heating. The ammonia separation unit (3) is installed direct below the storage unit (25).
