Abstract: A dough mixer includes a main unit with a motor arranged therein and a dough mixing assembly mounted thereon. The dough mixing assembly includes a dough mixing bowl, a top cover, a transmission shaft connected to the motor and is arranged in the dough mixing bowl, a dough mixing unit connected to the transmission shaft and including an upper end, and a scraper unit detachably connected to the upper end of the dough mixing unit. The scraper unit includes a first bowl wall scraper including a first blade fitted to an inner wall of the dough mixing bowl, a second bowl wall scraper including a second blade fitted to the inner wall of the dough mixing bowl, wherein the second bowl wall scraper is arranged opposite to the first bowl wall scraper, and a central scraper including a third blade matched with an outer wall of the transmission shaft.

Abstract: The invention discloses a dough kneading machine, including a main body on which a dough kneading component is mounted; the dough kneading component comprises a dough kneading bowl with a cover, in which a dough kneading drive shaft is set passing through a mounting hole on the bottom of the bowl and connecting to the main body at the lower end; a bidirectional dough kneading hook with a center shaft is mounted on the upper end of the dough kneading drive shaft; a first dough kneading hook and a second dough kneading hook with asymmetric structure are oppositely set on the center shaft and a center scraper is connected to the bottom of the center shaft. The dough kneading machine effectively ensures the stationarity during rotation operation of food processing, and the efficiency is two times as fast as that of unidirectional dough kneading hook.
