FIELD: technological processes. SUBSTANCE: method includes at least one treatment step (2a， 2b)， on which wood-based material (1) is treated by at least physical treatment， chemical treatment and/or physical and chemical treatment， and on which wood-based material (1) is treated by at least hydrolysis and steam explosion， and at least one liquid-solid phase separation step (6) after enzymatic hydrolysis (4)， to which lignin-based material (5) is fed and on which lignin fraction (7) and fraction (8) are separated， containing soluble carbohydrates. Produced lignocellulosic material (3a) contains more than 80??% of finely ground solid particles， which are fibrous particles of less than 0.2??mm， based on measurement results using an optical measuring device. Proposed is a wood-based material processing plant. EFFECT: group of inventions provides improved enzymatic hydrolysis and separation of lignin and fractions containing soluble carbohydrates to obtain product fractions of good quality. 31 cl， 5 dwg， 3 tbl， 8 ex
