The invention relates to a working without waste and without the use of chemical processes as well as a Vorrich device for continuous production of 2-furaldehyde, cellulose and lignin from lignocellulosic materials, which lead to a high yield of these substances. The drive Ver based on a two-stage continuous hydrolysis of disintegrated lignocellulose material under pressure into a first continuous hydrolysis reactor (5) and a downstream second continuous hydrolysis reactor (7), in which a two-stage hydrolysis is carried out; the resulting suspension is, in an expansion device (19) is extracted after pressing the liquid phase that contains the main content of 2-furaldehyde to atmospheric pressure and tion device in a Extrak (22), said lignin and Cellu loose can be obtained. The 2-furaldehyde is obtained from the FLÜS denominated phase through two-stage rectification under atmospheric pressure.
