Separation device, sheet production device, method for producing filtered material

Abstract

To provide a separation device capable of properly humidifying the filtered material. [Solution] The separation device comprises a sieve equipped with a mesh, a cover member forming a first chamber, a second chamber, a third chamber, and a fourth chamber on the surface side of the sieve, a motor that rotates the sieve so that the first chamber to the fourth chamber are sequentially circulated on the surface side of the sieve, a first pipe that blows air mixed with filtrate and foreign matter toward the surface of the sieve in the first chamber, a second pipe that sucks out the air mixed with foreign matter that has passed through the mesh from the back side of the sieve at a position opposite to the first chamber, a third pipe that sucks out the air mixed with filtrate from the surface of the sieve in the third chamber, a fourth pipe that blows air toward the back side of the sieve at a position opposite to the third chamber, and a humidifying pipe that blows humidified air toward the sieve from the surface side in the second chamber.
