  • Patent number: 11072888
    Abstract: Technology for efficiently extracting fiber from a feedstock containing fiber. A subunit has a mesh drum configured as a rotatable cylinder with mesh in at least part of its surface, and a case that houses the mesh drum. The case has a first opening and a second opening that communicate with a first area, and a third opening that communicates with a second area. First screened material is supplied from the first opening to the first area. The subunit discharges from the third opening waste, which is a first component of the first screened material moved by an air current from the first area to the second area, and discharges from the second opening by an air current processing feedstock, which is a second component of the first screened material that does not pass through the mesh drum with the air current and remains in the first area.
