Deep and wide grooves are formed alternately and continuously, and the downstream part of each of the shallow and narrow grooves in the raw material transfer direction and the downstream kneading groove adjacent to each of the shallow and narrow grooves in the helical width direction are formed in a flow path. Rotating screws for kneading are connected to each other.
