Abstract
A vacuum kneading and deaerating device has a rotatable body provided in a chamber held under a closed or pressure-reduced condition, and which is rotated in a horizontal plane around a basic driving rotation axis. A container holder is provided in the chamber rotationably on an operating rotation axis parallel to the basic driving rotation axis in a revolution edge portion of the rotatable body, and detachably holds a paste container such that a central axis of the paste container obliquely intersects the operating rotation axis. A driving mechanism rotates the rotating body and the container holder. A deaeration valve for opening an internal space of the paste container to an internal space of the chamber by the action of centrifugal force attending on the rotation of the paste container, or a paste material-impermeable and gas-permeable membrane, is provided in an opening portion of the paste container.
