A method for continuous saccharification of plant raw material by feeding the raw material as such or prehydrolyzed and a dilute sulphuric acid solution into a flow reactor in order to hydrolyze the raw material under pressure and at a high temperature, discharging dry solids and liquid from the reactor by expansion and separating liquid and solids, wherein the raw material and sulfuric acid solution are led through the reactor at equal rate, which is the same as required by the more easily hydrolyzable particles of the raw material, the solids and liquid together are discharged into the same blow tank and at least part of the separated coarse solid is returned into the reactor.

A method for continuous saccharification of a plant raw material comprising: feeding both the raw material and a dilute sulfuric acid solution through a flow reactor at a flow rate required to hydrolyze under pressure and at elevated temperature the more easily hydrolyzable particles of the raw material and maintaining the pressure and temperature required for hydrolysis in the reactor, the detention time of said raw material and said dilute sulfuric acid in said flow reactor being substantially equal; discharging dry solids and liquid containing monosaccharides together from the reactor into a common blow tank by expansion; separating in a separator the liquid and solids into one fraction containing liquid and fine solids and a second fraction containing coarse solids and recovering the liquid as a monosaccharide product while discharging the fine solids which contain mainly lignin; and recycling at least part of the separated coarse solids into the reactor.
