Continuous processing chambers

A continuous processing chamber for the treatment of a material comprising:

• a material shaft comprising an inlet and an outlet, the material shaft configured so that material introduced by the inlet may be transported through the material shaft and discharged through the outlet;
• and
• an inner gas transfer tube in fluid communication with the material shaft, the inner gas transfer tube comprising an inner filtration wall that encases at least a portion of the inner gas transfer tube providing fluid communication with both the material shaft and the inner gas transfer tube;
• or
• an outer gas transfer tube in fluid communication with the material shaft, the outer gas transfer tube comprising an outer gas transfer wall that encases at least a portion of the outer gas transfer tube and is in fluid communication with both the material shaft and the outer gas transfer tube;
• or
• both an inner gas transfer tube and an outer gas transfer tube;
• wherein the continuous processing chamber is configured to allow the gas fed through the inner or outer gas transfer tube to the material shaft to contact the material, thereby treating the material.
