Here is the setup my friend uses to clean corn with to use in a corn burner. It starts with 225 bushel in the gravity wagon and is extracted using a 6 hp shop vac. It will go through a Corn-Vac cleaner to remove dust and other small debris on the corn which goes into the shop vac. The rest falls into the bucket; once the bucket is full, turn the shop vac off and it will release all the corn from the bucket and it will fall through the Shur-Kleen to remove smaller kernels. All the clean corn then falls into another bucket.
