ABSTRACT:
An improved method for processing of xanthophyll-containing vegetative crops to yield a relatively xanthophyll rich high protein, essentially non-fibrous friable when dry particulate fraction primarily derived from non-vascular plant leaf or petal tissue, and a separate tougher, particulate fibrous fraction derived principally from plant stem and the leaf vascular xylem and phloem network. A system (20) which is useful for carrying out a preferred method includes a drying assembly (22) for drying crop to a moisture content of 15-30% by weight, a fractionating hammermill (24) to separate crop into a high protein xanthophyll-containing fraction and a high fiber fraction, and individual, downstream high protein and high fiber fraction processing assemblies (26, 28). The hammermill (24) includes an elongated housing (48); a rotor assembly (56) is situated within the housing (48) and includes a plurality of spaced outwardly extending hammers (86) each presenting a rounded leading impact surface (88). An internal screen (58) serves to separate the rotor assembly (56) from the second outlet (54). Blower means is connected to the hammermill for directing air into the hammermill housing to effect separation of a high protein xanthophyll-containing fraction and a high fiber fraction. The downstream processing assemblies (26, 28) serve to collect and optionally pelletize the individual xanthophyll-containing high protein fraction and the high fiber fraction.
