These are holding tanks that I built for Affiliated Foods in Texas.
These tanks hold 600 + sacks of potatoes, 60,000 + pounds. They have fully automatic conveyors on the top that fill the tanks from one end to the other with out dropping the potato more than 1'. The bottom of the tank has a conveyor also that lets the potatoes flow out the bottom on to other conveyors that take them where they need to go. Every thing on these tanks (all 9) is controlled from a touch screen mother cabinet with a ladder programed CPU to do certain functions as needed. Sorry I don't have the finished product photos.
