Abstract:
To prevent a solid content contained in a raw material from leaking through a slit.SOLUTION: An extrusion device includes a drainage part for draining a water content separated from a raw material to the outside. The drainage part includes a separator member 33 having a slit 32 for draining the water content separated from the raw material to the outside in a selective manner. The separator member 33 includes: a plate part 36 having a surface 36t; and a plate part 37 having a surface 37b facing the surface 36t, and laminated on the plate part 36. The slit 32 is formed between the surface 36t and the surface 37b, and the plate part 36 and the plate part 37 respectively have inner surfaces facing a cylinder part. A surface roughness of at least one out of the surface 36t and the surface 37b is coarser than a surface roughness of an inner surface 33s of either the plate part 36 or the plate part 37.SELECTED DRAWING: Figure 5
