ABSTRACT:
A food extruder including a barrel provided at one end with an outlet from which the food substance can be extruded, a rotatable screw positioned within the barrel that is capable of being rotated and moved longitudinally within the barrel, a handle member at a top end of the rotatable screw for manual engagement, and a rod member protruding from an upper portion of the handle member for insertion into a drill chuck. The rod member, in a preferred embodiment, has a hexagonal cross section, which facilitates insertion and securement within a drill chuck, so that the drill may be used to turn the rotatable screw, rather than having to turn it manually. Additionally, a hand grip member may be attached to the barrel member at a generally right angle thereto, so that a user may grip the hand grip while using the drill to turn the rotatable screw, in order to prevent the entire extruder from rotating.
