Provided is a kneading and stirring device having excellent self-cleaning performance and being capable of stable, long term operation. A plurality of equilateral-triangle-shaped stirring vanes (3) are secured to two rotating shafts (4) so as to be eccentrically disposed by a fixed amount in a fixed direction along the axial direction of the rotating shafts, the vanes being arranged parallel to each other in a processing chamber (2). Two sets of the stirring vanes (3) secured in the same position in the axial direction of the rotating shafts (4) rotate eccentrically while kept in a state in which one of the apices of one of the stirring vanes (3) is adjacent to the profile of the other stirring vane (3) when the rotating shafts (4) have been caused to rotate at the same speed in the same direction. A polycondensation resin (processed product) deposited on the outer periphery of the vanes is scraped away, and the resin deposited on the inner wall of the processing chamber (2) is scraped away at the apices adjacent to the inner wall of the processing chamber, whereby superior self-cleaning performance is achieved and more-stable, longer-term operation is made possible relative to devices that use conventional disc-shaped stirring vanes. |
