The invention relates to a sterilization process and device for neomycin sulfate production. A plate heat exchanger, a preheating tank and a spray drying tower are used for sterilization in neomycin sulfate production. The method comprises the following steps of: (1) introducing neomycin sulfate solution to the plate heat exchanger from a feed liquid inlet, also introducing steam tail gas generated in the production process from a steam tail gas inlet, and heating the neomycin sulfate solution to 78-90 DEG C by utilizing the steam tail gas; (2) introducing the heated neomycin sulfate solution to the preheating tank from the plate heat exchanger and heating for 3-5min in the preheating tank; and (3) introducing the neomycin sulfate solution to the spray drying tower for subsequent production processing after the specified insulation time. By adopting the structure, the efficient sterilization of the neomycin sulfate raw powder is realized, the product quality meets the market requirement, and at the same time,
