Abstract A kneading machine includes a pot the diameter of which gradually increases toward the top from the bottom thereof, and a rotatable blade centrally located at the bottom of the pot. At specified positions on the inside wall of the pot there are provided a plurality of projections jutting toward the center of the pot. The rotatable blade is formed of a circular body with a specified radius and an integrated combination of a large blade and a small blade provided on the body at a circumferential angle of separation of about 180°-270°. The small blade is a rectangular plate which is inclined at a given angle to the central vertical axis of the body. The small blade has a bottom side located on the same horizontal plane as the bottom of the body and a top side which gradually rises toward the body and which is integrated to a specified outside position located lower in the vertical direction than the topmost plane of the body. The large blade has a wing-shaped top side which gradually rises outwardly from adjacent the topmost plane of the body. The inside surface of the large blade is substantially an extension of the outside surface of the small blade. The large blade top side is inclined downwardly at a specified angle from the inner or trailing end thereof to the outer or leading end thereof. When the rotatable blade is fitted to a rotating shaft centrally provided at the bottom center of the pot, the outer end faces of the small blade and the large blade are respectively held at a specified distance from the opposed inside wall of the pot.
A kneading machine comprising: a pot having an open top and a diameter gradually increasing upward from the bottom thereof; a rotatable blade centrally installed at the bottom of said pot; a plurality of projections provided on the inside wall of said pot and inclined to the central vertical axis of said pot; said rotatable blade comprising a blade body, a small blade and a large blade integrally fitted to said body at a circumferential angle of separation of 180° - 270°; said small blade comprising a rectangular plate fitted to said body and extending outwardly therefrom and forwardly downwardly inclined relative to said central vertical axis of said body, the bottom of the small blade being on the same horizontal plane as the bottom of said body, said small blade having a top side integrally fitted to said body at a position thereof lower in the vertical direction than the top center of the body; said large blade having a wing-shaped top surface rising outwardly from a position adjacent the topmost plane of the body, said large blade having a trailing surface on substantially an extension of said top side of said small blade; and said wing-shaped top surface of said large blade being inclined downwardly from the trailing edge thereof to the leading edge thereof.
