Each silo stands 33.6 meters tall with a diameter of 24 meters, capable of storing 9,000 tonnes of grain. The first batch of five silos offers a total storage capacity of 45,000 tonnes. These air-supported silos feature integration of insulation, waterproofing, and structural layers, achieving an airtightness performance over six times higher than the national standard for high-quality grain depots. Coupled with air-conditioning temperature control and nitrogen-controlled atmosphere storage technologies, these silos significantly reduce their energy consumption, with operation and maintenance costs projected to drop by over 30% compared to conventional grain storage facilities.
