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).
