(ECNS) – China's first batch of three large inflatable grain silos, with a storage capacity of 9,000 metric tons each, was installed in central China's Hunan Province on Monday, according to China Coal Construction Engineering Group.

Standing at a height of 33 meters with a diameter of 24 meters, each air film silo offers a 20 percent increase in storage capacity compared to the previous generation.

With technological innovation, the grain silo takes only 33 minutes to fully inflate, nearly three times faster than previous inflatable grain storage facilities.

It boasts multiple innovative technologies, including optimized warehouse dimensions, a hydrophobic and oleophobic coating on the membrane material, and a revamped intelligent air pressure electro-control linkage system.

These advancements not only increase storage capacity, self-cleaning performance, and visual appeal but also enhance the warehouse's waterproofing, thermal insulation, and airtightness.

It marks the country's progress in applying next generatio grain storage technology.

A total of five inflatable air film silos were constructed and are expected to be ready for grain storage by the end of 2025.
