FIELD: textiles, paper.

SUBSTANCE: method of treatment of plant cellulose-containing materials includes the use of the device consisting of a housing, bottom and lid forming its working cavity, equipped with a means of its temperature-controlled heating, external means of recirculation of the liquid phase. The device comprises a working cavity which is divided into zones formed by the elements placed in the cavity, each of which consists of a cylindrical part and a perforated bottom with a plated filter screen located on it. Loading of the material in the device is carried out by its preliminary loading in the elements and their subsequent installation into the cavity. The elements are loaded with materials differing in characteristics. Replacement of one liquid phase in the device is carried out by displacement by the other liquid phase. Removal of products of each material treatment is carried out separately.

EFFECT: ability simultaneous treatment of several different samples of materials in the same modes and alignment of the characteristics of these samples.
