PURPOSE:To perfectly isolate from the outer air when the treatment is carried out by providing a hollow cylindrical can the top of which is closed and the open bottom of which is hermetically set to a hermeticable hollow vessel, and by driving the driven body in the inside of the can with the driving body provided on the outside of the can by the attraction of magnetic force. CONSTITUTION:In the reaction vessel in which a raw material is treated for production under the state isolating from the outer air, the driving body 40 is rotated with a driving shaft 9 by a motor provided on the outside of the hollow vessel 1. Then, by the attraction between the driving magnet 41 furnished to the driving body 40 and the driven magnet 35 furnished to a rotor assembly 25 disposed with the wall of the can 12 between the driving body, the driven magnet 35 is rotated to rotate the rotor assembly 25 in the hollow vessel 1. Consequently, by providing agitating blades, etc., on the revolving shaft 6 of the rotor assembly 25, the fluid to be treated in the vessel is agitated in the hermetic state under the isolation from the outer air. |
