Facility Feature
Cooksville Grain Co. Separating Corn, Soybeans to Reduce Truck Wait Time

The Cooksville Grain Co. annex is dedicated strictly to handling soybeans near Cooksville, IL.

Soybean annex adds 750,000-bushel, fully automated facility to operations.

Cooksville, IL — Privately-held Cooksville Grain Co. handles only two crops at its single location in Cooksville, IL – corn and soybeans.

But when those crops are harvested at the same time in the fall and both are being delivered to the elevator simultaneously, that can create a bottleneck and cause its busy patrons to wait in lengthy truck lines.

“When some trucks had corn and some had soybeans, we were having to make sure we were cleaning out the receiving pits completely from one commodity, before we began receiving the next one,” says General Manager Lori Mott, who has been with Cooksville Grain for 13 years. (Prior to that, Mott worked as an independent grain broker.)

Mott has been blessed with an active board of directors, and the solution they came up with was to build a second elevator about a block east of the existing elevator. The annex is dedicated strictly to handling soybeans, while the original elevator will handle corn.

22-acre site purchased for eight steel tanks

To make room for the new elevator, the board voted to purchase a 22-acre site, which Mott says will provide enough space for an eventual eight corrugated steel storage tanks. Until then, the unused land is being rented out for farming.

“It’s the Cadillac of grain elevators,” says Mott of the roughly 750,000-bushel, fully automated facility.

Cooksville Grain hired Koehl Bros., Fairbury, IL (815-692-2326), as general contractor and millwright on the project after taking bids. “Their work is very good, clean, and neat,” Mott comments. “We liked their design.”

In addition, SKS Engineers LLC, Decatur, IL (217-877-2100), did structural c engineering on the project.

Automated Electric and Service LLC, Le Roy, IL (309-962-8414), supplied automation systems, including a full motor control center, automated pit and loadout, and a PLC workstation with touchscreen controls.

Construction began during the summer of 2017 and was finishing up when Grain Journal visited in late June 2018.

Annex features 20,000 bph receiving leg

Soil conditions made construction a challenge at the site. It required excavation and 26 tons of fill material, although no pilings were needed.

Koehl Bros. constructed a pair of GSI 350,000-bushel corrugated steel tanks standing 72 feet in diameter, 96 feet tall at the eaves, and 115 feet tall at the peaks.

The tanks have flat floors, outside stiffeners, 12-inch GSI X-Series zero-entry sweep augers, 12-cable Rolfes@Boone grain temperature monitoring systems, and BinMaster tilt switch level indicators.

The Decatur Aeration-designed aeration system consists of a pair of 75-hp Chicago Blower centrifugal fans per tank supplying 1/7 cfm per bushel through in-floor ducting.

Incoming trucks supply grain through a 1,200-bushel mechanical receiving pit. The pit is enclosed in a concrete structure rather than the more common steel for durability over time.

The pit feeds a GSI 20,000-bph leg equipped with a single row of Tapco 20x9 vented buckets on 10-inch centers, mounted on a 22-inch ContiTech belt. At the top of the leg, grain passes through an arrangement of two-way valves, which in turn, sends it out to storage via GSI 20,000-bph overhead drag conveyors.

Each tank has a pair of sidedraw spouts and also can empty onto a 5,000-bph GSI drag in an above-ground tunnel running back to the receiving leg. The valves on top also can send grain via gravity spout to a 5,000-bushel Meridian surge tank over the receiving pit for truck loading.
