1. An apparatus for pretreatment for saccharification of lignocellulose biomass comprisinga mixing unit which mixes lignocellulose biomass and ammonia,a first heating unit which heats a biomass-ammonia mixture provided by the mixing unit,a separation unit which separates ammonia gas from the biomass-ammonia mixture heated by the first heating unit to obtain a biomass-water mixture,a transfer unit which transfers the biomass-water mixture separated by the separation unit to a later step,an ammonia water supply unit which supplies ammonia water having an ammonia concentration of 5 to 35 wt % to the mixing unit, andan ammonia recovery unit which recovers ammonia gas as ammonia water by dissolving ammonia gas separated by the separation unit in water,a first heat exchanger recovering heat from ammonia gas separated by the separation unit,a second heat exchanger recovering heat from the biomass-water mixture separated by the separation unit, anda heat supply unit supplying heat recovered from the first and second heat exchangers to the first heating unit.
