Abstract: A process and apparatus for recovering feed products from animal manure are disclosed wherein the manure is fractionated into a silage component, a high-protein feed supplement, and a third component consisting essentially of insoluble minerals and indigestible cellulosic particles. A slurry of the incoming manure is formed and allowed to ferment to encourage the bacterial conversion of nitrogenous compounds into true protein and to lower the pH of the slurry. Special separators are used to separate the fermented slurry into solid and liquid fractions. The solid fraction which consists of undigested fibers and grains is washed to provide the silage type component. Insoluble minerals and indigestible cellulosic particles of the manure which appear in the liquid fraction as fine solids are removed from the liquid fraction (by centrifuging) to provide the third component. The viscous liquid fraction may be used as a high-protein feed supplement or the water in it can be evaporated to provide a dry product.
