Abstract:
A vacuum degassing machine that degasses material to be processed by placing a rotating rotor 30 with a screen in a vacuum vessel, introducing a liquid material to be processed into the rotor 30 from the interior thereof and causing the liquid to pass through the screen 3 to refine the same, wherein the vacuum degassing machine is characterized in that: the screen 3 is a cylinder with a circular cross-section and is in the form of a porous plate in which a plurality of through holes are opened in the radial direction of the cylindrical screen 3; and the screen 3 is provided such that the area of inflow openings is greater than the area of outflow openings, where the inflow openings are openings of a plurality of penetration portions provided on the inner wall face of the screen 3 and the outflow openings are openings of the plurality of penetration portions provided on the outer wall face of the screen. Thus, the processing capacity of the vacuum degassing machine is improved without increasing the size of the device.
