Abstract
A method and apparatus for treating finely divided fibrous pulp with gas without overpressure in a continuous process. The bulk material is substantially continuously supplied to a reactor having one or more supporting floors having apertures of a shape and size which allow the finely divided material to form bridges across the apertures, said apertures also permitting a continuous flow of gas through the bulk material. The bulk material proceeds through the reactor as a consequence of the bridges being broken by breaking arms sweeping along the upper surface of the supporting floors.
