Method for making pet food flavor enhancer

摘要

A pet food flavor enhancer (46) is made from pieces of cleaned cattle hooves (10) by reducing the hoof pieces to a granular size (40) by tumbling the pieces of hooves within a rotary drum (62) having inwardly opening louvered openings (74) formed in the circumferential sidewall (66) of the drum. The louvered openings have sharpened cutting edges (76) so that the pieces of hooves are chipped as they strike the cutting edges. The chipped pieces of hooves are collected after passing through the louvered openings and are separated by size at a shaker table assembly (104). The shaker assembly separates the desirable granular hoof material product from larger hoof material (36) and smaller hoof material (42).
