Abstract
A rotating mill for comminuting a product, such as a food product, is disclosed in which the shape and orientation of the impeller blades, as well as the increased peripheral speed of the impeller, produce a finely comminuted product that was heretofore only capable with a multi-stage production process. The impeller rotates within an annular array of knives and the product is fed into the center area of the impeller. Centrifugal force urges the product across the rotating impeller, and into contact with the impeller blades and the knife array. The impeller has a generally circular impeller body that is rotatable about a generally centrally located rotational axis and a plurality of impeller blades attached to the impeller body. Each of the impeller blades has a product directing surface that extends parallel to an axis extending in a generally chordal direction across the impeller body and a product impact surface.
