Moreno, F E

In an extraction method and apparatus for extracting low biomass solid materials from a pneumatic transport line, the stream of gas having the solids entrained therein is caused to flow over a toothed extractor wheel. The toothed wheel picks out of the stream the solid materials which are then doffed from the tooth extractor wheel by the vanes of a rotating valve which seals the pressure of the pneumatic transport line from the ambient. The material doffed from the extractor wheel falls into the region between the vanes of the rotary valve and is then removed from the system as the vanes of the valve rotate. The air stream which is inducted into the extractor is first caused to pass through a diffuser which slows the velocity of the air stream and then the air stream is cause to flow along a curved duct section toward the extractor wheel causing the solid materials to flow to the outside of the curved duct section and into the extractor wheel to facilitate extraction.
