A device for stirring (kneading) and defoaming a material to be kneaded is known. When such a rotation and revolution type stirring and defoaming device is operated in the atmosphere, stirring and defoaming are basically performed simultaneously, but advanced defoaming in which bubbles of 1 micron or less becomes a problem. If there is a demand, operating the stirring and defoaming device in a vacuum can obtain a much better defoaming effect. This fact has been demonstrated from the fact that a defoaming effect has been obtained by operating a stirrer of another type such as a propeller mixer or a three-roll kneader in a vacuum chamber.

(B) Next, by operating a drive mechanism (not shown), the container holder 10 is rotated around the rotation axis and the revolution axis in a clockwise direction at a rotation speed of 800 rpm, for example, and at a rotation speed of 2000 rpm, for example. Then, the material W to be kneaded stored in the storage container 13 is stirred and defoamed. At this time, since the first passage 41 is formed in the inner axis of the rotation shaft 20 and the third passage 43 is formed in the inner axis of the revolving shaft 30, the container holder 10 can be smoothly moved without breaking the rotational balance. And revolve around.

Here, the inside of the container holder 10 is evacuated by operating the vacuum pump 52. Thereby, since a vacuum acts on the material to be kneaded W during the stirring and defoaming operation, an excellent defoaming effect can be obtained. The material to be kneaded W
The timing of applying a vacuum to the air is arbitrary, such as the first half, the middle, the second half, and the entire time of the work during the stirring and defoaming work.

At the same time, the state of the material W to be kneaded in the storage container 13 is observed through the transparent lid 11 by the visual recognition means 63 (see FIG. 5). At this time, the lid 11 is not provided with the flexible suction hose 61 that interferes with the conventional stirring and defoaming apparatus A ′, so that the visibility is good.

(C) After a sufficient stirring and defoaming operation is performed, the operation of the driving mechanism and the vacuum pump 52 is stopped, and the vacuum release valve 54 is opened, whereby the container holder 10 is opened.
Atmospheric pressure inside. Thereby, the lid 11 can be removed from the container holder 10, the storage container 13 can be removed from inside the container holder 10, and the kneaded material W that has been stirred and defoamed can be obtained.
