A food mixing machine ( 10 ) has a rotatable shaft ( 18 ) which is attached to the shaft ( 21 ) of an agitator ( 20 ). The shaft ( 21 ) carries a ring ( 24 ) and a disk ( 23 ), and the ring ( 24 ) carries a cloverleaf-shaped chip ( 25 ). The chip ( 25 ) has opposed, generally flat lobes ( 27 ) with the opposed lobes ( 29 ) positioned between the lobes ( 27 ). The lobes ( 29 ) are inclined relative to the lobes ( 27 ). Cutout areas ( 31 ) are formed between the lobes ( 27, 29 ), and as the agitator ( 20 ) is being rotated by the shaft ( 18 ), a leading edge ( 32 ) on the lobes ( 27, 29 ) at the cutout areas ( 31 ) contacts the food being mixed. The leading edges ( 32 ) have a larger radius of curvature than the trailing edges ( 33 ) on each lobe ( 27, 29 ).
