Abstract: A dough mixing and kneading device which comprises a horizontally disposed container including an elongate cylindrical space closed by walls at the ends of the container and three blades within the space extending lengthwise therein. The blades are secured to and driven by drive shafts protruding through the end walls of the container. The blades when driven rotate along circular paths radially spaced from each other, one of the blades rotating closely adjacent to the inside wall surface of the container thereby acting as a scraper. A lengthwise opening at the top of the container is provided for loading the container with dough and discharging the dough after mixing and kneading by rotating the container about its center axis. A fixedly mounted cover closes the opening when the opening is turned into its upwardly facing position.
