    Abstract: The invention relates to a method and an apparatus for an enzymatic hydrolysis in which plant based raw material is hydrolysed by means of enzymes. The plant based raw material (1) is fed to the first enzymatic hydrolysis stage (2), the plant based raw material (1) is hydrolysed in at least two enzymatic hydrolysis stages (2,4), a liquid fraction (5a,5b) comprising carbohydrates is separated from a solid fraction (6a,6b) in a solid-liquid separation stage (7a,7b) after each enzymatic hydrolysis stage (2,4), and the solid fraction (6a) is supplied to the next enzymatic hydrolysis stage (4) in which the solid fraction is treated, and the solid fraction (6b) is recovered after the last solid-liquid separation stage (7b). Further, the invention relates to the liquid fraction and the solid fraction and their use.

    Abstract: In a method for producing nanofibril cellulose, cellulose based fibre material, in which internal bonds in the cellulose fibre have been weakened by chemical modification, are supplied, for separating fibrils, through several counter-rotating rotors outwards in the radial direction with respect to the rotation axis of the rotors in such a way that the material is repeatedly subjected to shearing and impacting forces by the effect of the blades of the different counter-rotating rotors, whereby it is simultaneously fibrillated.

    Abstract: In a method and an apparatus for an enzymatic hydrolysis in which plant based raw material is hydrolysed by means of enzymes in at least one enzymatic hydrolysis stage. A plant based feed (1) is fed to the enzymatic hydrolysis stage (2) in which the plant based feed is hydrolysed. A liquid fraction (3) comprising carbohydrates is separated from a solid fraction (4) in a solid-liquid separation stage (11). At least a part (5) of the solid fraction (4) comprising enzymes is recirculated to the plant based feed (1) of the enzymatic hydrolysis stage (2) or to the enzymatic hydrolysis stage (2), and a rest part (6) of the solid fraction (4) is recovered. Further, the invention relates to the liquid fraction and the solid fraction and their use.
