A lignocellulosic biomass saccharification pre-treatment device is provided, which is capable of easily recovering ammonia water to be used in a pre-treatment for saccharification of a lignocellulosic biomass and putting in recycle use. The lignocellulosic biomass saccharification pre-treatment device has a mixing unit 2 for mixing lignocellulosic biomass and ammonia, a heating unit 3 for heating the biomass-ammonia mixture, a separation unit 4 for separating ammonia gas from the biomass-ammonia mixture to obtain a biomass-water mixture, and a transfer unit 6 for transferring the biomass-water mixture to a later process 5. The device has ammonia water supply unit 8 for supplying ammonia water to the mixing means 2, ammonia recovery unit 20 for recovering ammonia gas as ammonia water, heat-of-dissolution recovery unit 24 for recovering heat-of dissolution generated when ammonia gas is dissolved in water, and heat pump unit 30 for generating heat to be supplied to the heating unit 3 using at least the heat-of-dissolution as a heat source.
