This answers that question... Yes! In fact, there are also grain elevators too! I took a class last semester at IU called "Food Politics: the Politics of What's for Dinner" and it was mostly about the corn industry dominating the food market. We watched several documentaries about large corporations taking over and putting small farms out of business. Many old grain elevators such as this one are abandon and replaced with much larger industrial elevators. I thought this was a neat example of that pattern throughout the midwest!
