This invention discloses a method for producing granules that reduces the loss of active ingredients, relating to the field of granule preparation technology. This method addresses the problem of active ingredient loss in traditional granule production due to high temperatures, oxidation, mechanical friction, and solvent residue. It employs a four-stage process—low-temperature pretreatment, inert gas-protected granulation, gradient drying, and nano-coating and end-capping—combined with the application of a specialized composite binder, significantly improving the retention rate of active ingredients. Experimental data shows that granules produced using this method have a higher retention rate of active ingredients than those produced by traditional methods, while also exhibiting high granule formation rate and dissolution rates that meet relevant standards. The process of this invention is highly stable and widely adaptable, and can be widely applied to granule production in the pharmaceutical, pesticide, food, and feed industries.
