Fiber processing device and fibrous feedstock recycling device

A fibrous feedstock recycling device comprising:

• a defibrator configured to defibrate feedstock containing fiber;
• a processor configured to process defibrated material produced by the defibrator;
• a conveyor configured to convey the defibrated material by an air conveyance current from the defibrator to the processor;
• and
• a separator disposed to the conveyor, and including
• a mesh member configured as a rotatable cylinder having mesh in at least part of the circumferential surface;
• and
• a case housing the mesh member, and having a first opening and a second opening communicating with a first area inside of the mesh member, and a third opening communicating with a second area outside the mesh member;
• the separator supplying separator feedstock containing fiber from the first opening to the first area,
• discharging from the third opening a first component of the separator feedstock that past by an air current through the mesh member and moved from the first area to the second area, and
• discharging from the second opening a second component of the separator feedstock that did not pass through the mesh member by the air current and remained in the first area.

A fibrous feedstock recycling device comprising:

• a separator including a mesh member configured as a rotatable cylinder having mesh in at least part of the circumferential surface, and a case housing the mesh member, and having a first opening and a second opening communicating with a first area inside of the mesh member, and a third opening communicating with a second area outside the mesh member;
• an air current generator configured to produce an air current inside the case;
• and
• a controller configured to change a state of the air current generator between a first state producing an air current from the first area to the second area, and a second state producing an air current from the second area to the first area.
