Abstract: A process for continuously producing dried protein concentrates, namely blood meal, from an aqueous solution of animal blood, in which the solution is atomized in superheated steam at a temperature of about 400.degree. C. The atomization of the solution is accomplished, at least in part, by a centrifugal atomizer that throws the solution radially outward in an extremely thin layer of finely divided droplets having diameters less than 100 microns. The small droplets pass into the stream of superheated steam, which causes the liquid to evaporate, and the dried blood solids to precipitate to the bottom of the collector where they are discharged by a conveyor. The superheated steam, which was cooled to about 200.degree. C. by the drying process, goes to a cyclone separator which removes any entrained solids, and is then returned to the heat exchanger, where it is again heated to about 400.degree. C. for re-use in the process.
