All of the corn that is put in to 50 lb bags or in barrels is cleaned by a rotary grain cleaner. The corn passes through a 1/2 inch screen then over a 1/4 inch screen. This removes any larger than 1/2 inch so the customer gets corn that should not plug a normal deer feeder. The barrels are filled from a overhead tank that you can drive a pickup truck under so you do not have to handle the barrels when we fill them.
