摘要：
A process for the production of animal feed additives from fermentation broth containing L-lysine is disclosed. The process does not require filtering of biomass in order to remove the biomass and produces granulated lysine of controllable lysine content with a high bulk density, low viscosity, and a low hygroscopic property which does not require the addition of an anti-absorptive substance. In this process, a lysine fermentation broth produced after slant culture, flask culture, seed process, and cultivation process is concentrated to a solid content of about 44˜52%. A product with low hygroscopicity, high bulk density, and the intended amount of contents is produced after being mixed with substances for controlling the amount of contents and granulated by coating the surface of the seeds. This process enables a production of animal feed additives having a lysine-HCl content of at least 65%, a water content of at most 3%, and a bulk density of 670±50 kg/m3.
