PRODUCT DESCRIPTION

Zhongsu Hengda’s grain-grade nitrogen generators deliver 99.9% pure nitrogen, tailored for critical scenarios in grain storage to enable cost-effective grain preservation and safer long-term storage management.

In grain preservation, precise nitrogen output displaces oxygen in silos (for wheat, corn, rice, etc.), curbing over-reliance on chemical insecticides and fungicides and cutting microbial growth (mold, pests) by up to 90%, reducing grain spoilage waste. For safer storage management, the food-contact-safe nitrogen replaces potential harmful inerting agents, and its dry, inert property prevents oxidation of stored grains (like high-moisture corn, oil-rich soybeans) during long-term storage, preserving grain nutritional quality and market value.
