Flow distributor and reactor using such flow distributor

A reactor for performing, by means of solid reaction members, a biological or chemical transformation, or physical or chemical trapping from, or release of agents to, a fluidic media, said reactor comprising a vessel in which a cylindrical flow distributor has been mounted, said cylindrical flow distributor comprising:

• a top wall;
• a bottom wall comprising a central through going opening;
• an outer wall extending between the top wall and the bottom wall;
• an inner wall;
• and
• a means for rotating the cylindrical flow distributor;
• wherein the outer wall comprises a first plurality of longitudinally extending ribs arranged side by side along a longitudinal centerline CL of the flow distributor with gaps extending in the circumferential direction between two adjacent ribs, and a circumferentially extending first scaffold encircling and being fixedly attached to a peripheral outer surface of said plurality of longitudinally extending ribs,
• wherein the inner wall comprises a second scaffold having an extension along an axial direction of the flow distributor, and a plurality of consecutive turns of a second wire being fixedly attached to an outer surface of said second scaffold, such that axially extending gaps are formed between each turn of said second wire;
• and
• wherein the top wall, the bottom wall, an inner envelope surface of the outer wall and an outer envelope surface of the inner wall facing the outer wall together define a confinement configured to contain solid reaction members or a rigid body of a reaction member material.
