摘要： A powder collection unit includes a powder storage having an inlet through which powder including fibers enters and an outlet through which the powder exits, a delivery screw having an elongated shape, disposed in the powder storage, and configured to rotate about a rotation axis to send out and discharge the powder through the outlet, and a powder collection portion coupled to the outlet and having an inner space that collects the powder discharged through the outlet. An end portion of the delivery screw that is adjacent to the outlet protrudes outwardly from the powder storage through the outlet and resides in the inner space of the powder collection portion.

摘要： A separator as part of a sheet manufacturing apparatus has a mesh drum configured as a cylinder that can rotate and has mesh in at least part of the side; and a case that houses the mesh drum. The case has a supply port and a recovery port that communicate with an inside area, which is the inside of the mesh drum; a discharge port that communicates with a discharge area, which is outside the side of the mesh drum; and an inside wall segregating at least part of the inside area, forming a material recovery area. First screened material is supplied from the supply port to the inside area. In the material recovery area, the separator recovers accreted material, which is first screened material that was supplied through the supply port and accreted on the inside surface of the mesh drum, from the recovery port.

摘要： A material supply device includes a supply section that supplies a small piece made of a material containing a fiber, a weight measurement section that detects a weight of the small piece supplied from the supply section to a receiving portion, and a supply amount adjustment section that adjusts a supply amount per unit time of the small piece supplied by the supply section, based on a detection result detected by the weight measurement section. The supply section has a storage portion that stores the small piece, an outlet that discharges the small piece from the storage portion, and a shutter that opens and closes the outlet.

摘要： 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.

摘要： A processing device, a sheet manufacturing apparatus, a processing method, and a sheet manufacturing method that suppress damage to a substrate when removing color material from the substrate, and are useful for recycling the substrate after color material is removed, are provided. A processing device has a color material removal device including at least one discharge nozzle configured to discharge particles containing cellulose to a substrate holding color material, and remove the color material from the substrate. The color material removal device preferably has a double-walled conduit construction having an internal conduit and an external conduit in which the internal conduit is inserted, at least one of an opening to the internal conduit and an opening to the external conduit functioning as the discharge nozzle.
