Vacuum kneading and deaerating device

A vacuum kneading and deaerating device comprising a rotating body for revolution, which is provided rotationably in a horizontal plane around a basic driving rotation axis extending in a vertical direction in a chamber the internal space of which has been held under a closed or pressure-reduced condition, a container holding means which is provided in the chamber rotationably on an operating rotation axis extending in a vertical direction in a revolution edge portion of the rotating body for revolution and detachably holds a cylindrical paste container, in which a paste material to be kneaded and deaerated has been contained, in a state that a central axis of the paste container obliquely intersects the operating rotation axis, and a driving mechanism for rotating the rotating body for revolution and the container holding means, wherein

• a deaeration valve for opening an internal space of the paste container to the internal space of the chamber by the action of centrifugal force going outward in a radial direction of the rotating body for revolution attending on the revolution and rotation of the paste container is provided in an opening portion of the paste container for placing the paste material in the paste container.
