Dry ingredients <br /> consist of cereal grains, dry animal proteins, and vitamin and mineral supplements. The dry <br /> ingredients are delivered in bulk or bagged form. The bagged ingredients will be stored in a dry <br /> warehouse. The bulk ingredients will be stored in bins and silos. Fats and oils are stored in liquid <br /> tanks within a contained tank farm. The fresh meat is shipped in reusable totes and stored in a cooler <br /> room. <br /> The dry ingredients first are mixed together in a three-ton mixer, and then transferred to a hammer <br /> mill for more extensive grinding to turn into a mash. The mash is then sent to the extrusion process <br /> where the fat/oil and fresh meat are added. The extrusion process uses time, temperature, heat and <br /> pressure to cook the product. The product is cooked to a minimum of 190°F. This process creates a <br /> very small amount of scrap which will be reworked or sent to an appropriate disposal facility. <br /> 010107.00, Task I Lawrence&Associates <br /> w:Iclientsl diamond pet foods1010107.00-ripon rowdldiamondpet_rowdjune2011_draft.docx <br />
