Abstract

Method and apparatus for quickly and effectively grinding kernels of grain, such as wheat or corn, coffee beans, and the like, in a food processor producing a finely divided or flour-like consistency food product or condiment. Nutritious home-ground whole-grain flour can be conveniently and quickly made. The kernels, grains, beans, or other food products to be ground are introduced into a hopper positioned above the bowl of the food processor and located above a grinder assembly including a downwardly converging then diverging stator grinding member which encircles a rapidly rotating rotor grinding member having a vertical axis of rotation and being positioned within the stator member. This rotor grinding member is coupled to the vertical tool shaft of the food processor which extends up into the bowl. The separation between stator and rotor grinding members is manually adjustable and settable by a hand knob located above the grinder assembly for controlling the consistency and fineness of the ground product, which is deposited from the grinder assembly into the bowl. The illustrated grinder attachment for a food processor may be conveniently operated, adjusted, controlled and cleaned in a safe, efficient manner utilizing without alteration the basic components of the food processor, namely the motor drive, safety interlock system, as well as the bowl.
