Method for the production of a feed additive, animal feed additive, and animal feed A process for the production and feed additives of a fermentation broth containing l-lysine is set forth. The process does not require biomass filtration to remove biomass and produces controllable plant purity granular lysine with a high mass density, low viscosity, and low hygroscopic property, which does not require the addition of an anti-absorption substance. In this process, a lysine defermentation broth, produced after slant cultivation, flask culture, seed process and cultivation process is concentrated to a solids content of about 44-52%. a product with low hygroscopicity, high mass density, and the intended amount of purity is produced after mixing with purity control substances and granulating through seed surface coating. This process allows the production of animal feed additives having a plant-hcl purity of at least 65%, a water content of at most 3%, and a mass density of 670 + 50 kg / d. |
