ABSTRACT:
A method and apparatus in defibration of wood chips or similar vegetable material for conveying in steam pulp produced in a refiner (2) to a separator (7) for separating steam and pulp. The separator is bounded against the atmosphere and is kept pressurized by steam, while a limited amount of excess steam is led off. A flow of steam liberated from the pulp is taken from the separator and given an increased pressure for utilization in extracting pulp from the refiner. The steam flow is hereby led through the refiner and further to the separator, whereby the pulp is transferred to the separator by the steam which thus circulates to a considerable extent, said steam having been given the higher pressure either in the refiner itself, by means of pressure increasing means (19) therein, or upstream of the refiner in a separate pressure increasing means (11).
