Abstract

A vacuum deaerator degasses material to be processed by placing a rotating rotor with a screen in a vacuum vessel, introducing a liquid material to be processed into the rotor from the interior thereof and causing the liquid to pass through the screen to refine the same. The vacuum deaerator is characterized in that: the screen 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; and the screen 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 and the outflow openings are openings of the plurality of penetration portions provided on the outer wall dace of the screen. Thus, the processing capacity of the vacuum deaerator is improved without increasing the size of the device.
