Patent ID: 8486228

Claim:
A lignocellulosic biomass saccharification pre-treatment device comprising: a mixing unit configured to obtain a substrate mixture by mixing lignocellulosic biomass serving as a substrate and ammonia water; a reservoir unit configured to obtain a pretreated material for saccharification in powder form in which lignin is dissociated from the substrate or the substrate is swollen by storing the substrate mixture obtained by the mixing unit; and a separation unit configured to separate ammonia gas continuously from the pretreated material for saccharification in powder form by heating the pretreated material for saccharification supplied from the reservoir unit, wherein the device further comprises: an ammonia recovery unit configured to recover the ammonia gas as ammonia water by dissolving the ammonia gas separated in the separation unit in water; a first heat recovery unit configured to recover heat-of-dissolution generated when ammonia gas is dissolved in water in the ammonia recovery unit; and a heat supply unit configured to generate heat to be supplied to the separation unit by transferring the heat-of-dissolution recovered by the first heat recovery unit to the separation unit.
