FIELD: biotechnology.
SUBSTANCE: group of inventions relates to biotechnology. Proposed is a plant and method for increasing concentration of soluble carbohydrates-containing fractions, as well as fraction obtained by said method containing soluble carbohydrates and solid fraction. Plant contains facilities for production or treatment of lignocellulose material, supply device for direction of lignocellulose material into separation device for liquid and solid phases, a recirculation device and a means of removing solid substances and a portion containing soluble carbohydrates from the plant. Method includes treatment of initial material for production of lignocellulose material, separation of fraction and/or flushing filtrate containing from soluble carbohydrates from lignocellulose material, recycling of a portion of the soluble carbohydrate-containing fractions and/or flushing filtrate into the lignocellulosic material and removal from the solid-phase separation step and the fraction containing the soluble carbohydrates.
EFFECT: invention ensures production of fraction containing soluble carbohydrates and solid fraction with high concentration and quality, as well as minimization of amount of waste water and reduction of processing costs.
