Abstract
A center plate for a rotor in a pulp refiner has a surface provided with at least one feeding wing for directing lignocellulose-containing material towards a periphery of the center plate. The at least one feeding wing is an elongated protrusion arranged such that its second end is arranged further away from a center of the center plate than a first end and is also displaced relative to the first end in a direction opposite to a direction of rotation of the rotor. The at least one feeding wing includes at least one opening allowing steam to flow through the opening in a direction having a component directed opposite to the direction of rotation.
