Abstract

A method of producing fiber pulp from lignocellulose-containing fiber material, where the fiber material first is fed into a preheater (10) and preheated and the preheated material thereafter is discharged to a refiner (18) where the fiber pulp is produced by defibration of the fiber material. The fiber material is held in the preheater (10) for a predetermined dwell time, irrespective of the fiber pulp production, by measuring the fiber pulp production and using it for controlling the level of the fiber material in the preheater (10). <IMAGE>
