System for producing lysine product

The utility model discloses a system for producing lysine products, which comprises a first subsystem and a second subsystem, wherein the first subsystem is used for producing products containing lysine hydrochloride, the second subsystem is used for producing products containing lysine sulfate, the first subsystem comprises a solid-liquid separating device, the second subsystem comprises a third concentrator, and the solid-liquid separating device is connected with the third concentrator. A large amount of solid waste materials generated in the process of producing high-purity lysine hydrochloride are applied to the process of producing low-concentration lysine sulfate through the system for producing the lysine products, and therefore the environmental pressure is reduced, and the processing cost of so-called wastes is saved; and on the other hand, because a large amount of protein and other kinds of amino acids are contained in the so-called wastes, the substances can also be used as nutrient substances for breeding animals, and the nutrient substances are also effectively utilized.
