The stirring device employs an agitator prop having claws or fingers formed thereon to break up balls of dry ingredients, a shear plate to strain and shear ingredients forced therethrough by operation of the agitator prop and a pump prop. The agitator and pump props have reverse pitches with respect to each other such that both props push the ingredients toward the shear plate.
