PCT No. PCT/DK89/00122 Sec. 371 Date Jan. 29, 1990 Sec. 102(e) Date Jan. 29, 1990 PCT Filed May 16, 1989 PCT Pub. No. WO89/11797 PCT Pub. Date Dec. 14, 1989.Continuous hydrolyzing of keratinaceous material is effected in an elongated hydrolyzing vessel (1) under suitable pressure and temperature which is established by direct steam injection through injection valves, whereby the product mass is heated, fluidized and agitated at one and the same time. An inlet chute (2), which is closed in a pressure-proof manner, leads the material in batches and at intervals into the vessel (1), and an outlet chute (3) at intervals leads the hydrolyzed material to an economizer (4) and further to a pressure-free removal vessel (10). The product mass in the hydrolyzing vessel (1) moves through the vessel as plunger flow established by the overpressure in the inlet chute (2). |
