Cooperative Farmers Elevator New Feed Mill Design - Ocheyedan, IA

Replacement mill more than triples original facility's capacity

To better serve its growing customer base, Cooperative Farmers Elevator (CFE) invested in a new, 780,000 tons / year feed mill to replace its aging on-site mill. In collaboration with design-build contractor Younglove Construction, LLC, VAA provided structural engineering and industrial architecture services for the $26 million project.

Our Approach to CFE New Feed Mill Design

The structural team designed the mill’s slipform concrete tower erected by a 100-person crew in seven days. In addition, VAA’s engineers designed the plant’s foundations, steel floors, equipment supports and two 12-ton weigh lorries central to the mill’s loadout operations. The plant is capable of loading two trucks every eight minutes for a total of 125 trucks / day, and the lorries’ design allows truck drivers to remain in their vehicles, improving the safety of the loadout process.

An overhead conveyor connects the new plant to CFE’s nearby grain elevator, and the structural engineers provided detailed design to confirm proper support for the conveyor was in place. The architectural team performed Life Safety Code Analysis, defined occupancies and reviewed means of egress to ensure optimal safety for the mill’s employees as well as compliance with applicable codes.


One of the largest feed mills in the state, the new facility more than triples the original mill’s capacity to 2,336 tons of finished feed per day. The plant features a 240 tons-per-hour batching line, a 165 tons-per-hour hammermill and rollermill grinding system and a 70 tons-per-hour pelleting line to produce both mash and pelleted swine feed. At peak capacity, it can produce two-thirds of the co-op’s total daily feed production of 4,500 tons from nine locations.
