Chad Kuhlers, Chief Executive Officer of Golden Grain Energy, said: “This system will increase Golden Grain Energy’s grain storage from approximately 1.275 million bushels to nearly 3.5 million bushels.”

“Our current grain storage time is about 10 days, after adding this grain bin, storage time will increase to about 30 days. In addition, the grain receiving capacity will increase from 40,000 bushels/h to 65,000 bushels/h.”

Sheffield-based Sukup Manufacturing Co. is responsible for building this giant metal silo.

According to Sukup, after confirmation with their competitors, no one has ever built such a large free-span grain bin, which is the largest grain storage silo in the world.

In 2018, Sukup announced that it had set the largest silo record with a diameter of 156 feet (47.55m).

Sukup has built 2 sets of such silos for the ethanol plant Elite Octane, each one can store nearly 2 million bushels of grain.

This new silo bin in Wabaso, Minnesota cost 905,000 pounds of steel & took about 3 weeks to complete the project.

Due to the limitation of building height, this silo is 114 feet (34.75m) high.
