Abstract: An automatic bread baking machine wherein, at a predetermined time prior to a preset time, water is supplied into a container, in which the ingredients of bread are mixed into the water by rotating a rotary vane provided in the container, producing dough. A fixed rod is provided in the container adjacent to and spaced from the rotary vane, and the dough is twined around the fixed rod by the rotary vane and kneaded at comparatively low speed by the cooperation of the rotary vane and the fixed rod. The dough temperature is sensed by a temperature sensor disposed in the fixed rod, and when the sensed temperature has reached a predetermined value, the dough kneading operation is terminated. The water is supplied into the container from a water tank covered with a heat-insulating layer. An ice box for containing ice is provided in the water tank, and when the ambient temperature is higher than a predetermined value, cold water is supplied to the container.
