FIELD: technological processes.
SUBSTANCE: invention relates to vegetal materials extrusion and may be used for determination of properties of wood sawdust being extruded. The device includes a cylindrical chamber for preliminary compression of the material being pressed that has a removable draw plate in a cylindrical shell, position on the butt-end wall of the chamber on a strain-measuring support. The removable draw plate is fixed on the butt-end wall with the help of the shoulder on the draw plate shell.
EFFECT: invention ensures measurement precision improvement and the device technological functionalities extension.
