FIELD: chemistry.
SUBSTANCE: present invention discloses a boiling method and cooking system, where a partially cooked source of cellulose fibres is compressed during boiling to produce high-molecular weight lignin and fibrous mass.
EFFECT: invention enables to create an environmentally friendly method of pulping the cellulose fibre source, which enables to obtain fibrous mass and high-molecular weight lignin, as well as to create a method of producing fibrous mass from a source of cellulose fibres, consuming a small amount of energy when converted into a fibrous mass with high content of fine fractions.
