Abstract: A food processor wherein the output member of the prime mover extends vertically upwardly into a removable bowl and drives a rotary torque transmitting member having at its upper end a set of teeth arranged to mate with the teeth of a gear provided in a rotary juice extractor which is installed in a receptacle on top of the bowl. The torque transmitting member is a single-purpose part or it can constitute an adapter with additional external teeth arranged to drive a tool at a level below a cover which replaces the receptacle or a tool at a level directly or closely above the bottom portion of the bowl. The receptacle has a perforated bottom wall which permits juice to descend into the bowl, and the juice extractor rotates in the receptacle about an axis which is parallel to and remote from the axis of the torque transmitting member.
