A means for fluffing cellulosic pulp that should be treated in a gaseous environment, e.g., bleached with a gaseous bleaching agent, consists of a rotary breaker inserted in an inlet chamber at the top of the container in which the treatment takes place. The breaker comprises a hub carried by a vertical shaft and a number of inclined vanes distributed over the cylindrical face of said hub and having serrated edges working upon a plug of pulp continuously fed into said inlet chamber through a horizontal conduit having its orifice opposite the breaker.
