Processing Facilities
The Sun Prairie processing facility is second to none. Built in 1990, the processing tower is designed to handle up to 600 bushels an hour of corn or soybeans and the 9000+ acres that are brought into this facility every year. The plant can store up to 200,000 bushel in bulk storage and 200,000+ as bagged seed in its warehouse.

The facility goes beyond raw capacity. All equipment is geared to gently handle seed in order to maintain the highest germination and quality. All seed is moved using belt conveyors, bucket elevators and let-down legs to prevent seed from falling long distances. The plant has a full complement of machinery to clean out debris and damaged seed and to accurately size seed. The warehouses are all heavily insulated to maintain germination until the seed is ready for delivery.

The processing tower is also heavily computerized and can be run by only one person. It is also equipped with a dual dust control system. This makes it an environment-friendly and clean place to work.

Tours of the facility are welcome, with best viewing from September to January.
