A food mixer (10) includes a rotatable shaft (18) which is connected to
the shaft (21) of an agitator (20). The agitator (20) includes an upper
disk (23) attached to the shaft (21) and a lower disk (28). Slat walls
(27, 29) extend from the upper disk (23) to the lower disk (22) and slat
walls (27, 29) are curved so as to together forming a parabolic ring. A
central blade (33) extends from the upper disk (23) to the lower disk
(28) between the slat walls (27, 29). Both the upper and lower disks (23,
28) are circular and are curved upwardly in one direction and curved
downwardly in a direction transverse to the one direction.
