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.degree.-270.degree.. 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.
