The invention relates to the technical field of food processing, in particular to a dough making and kneading device for food processing. The dough making and kneading device comprises a shell, wherein a feeding hopper is arranged at the top of the shell, the bottom end of the feeding hopper is connected with a dough making mechanism arranged on the inner side of the shell through a material guidepipe, and a dough kneading mechanism is arranged on the lower side of the dough making mechanism. A plurality of guiding plates fixedly connected with the shell are arranged between the dough kneading mechanism and the dough making mechanism. By arranging the dough mixing mechanism, automatic water adding and dough mixing can be achieved, the dough making efficiency is improved, the workload of people is reduced, flour and water can be mixed more uniformly, and the dough making quality is improved; by arranging an adjusting mechanism, intermittent water injection can be achieved in the doughmaking process; and a driving mechanism is arranged, clamping blocks on two sides are made to move left and right repeatedly through a second motor, a pull rod drives the clamping blocks to move, andbesides, up and down repeated movement of a pressing block can be achieved through a connecting mechanism, and therefore, dough is comprehensively extruded, and dough kneading is achieved.
