I figured from the photo that they piled 3 high and 2 wide but didn't think they would pack 13 deep. That's interesting to learn - thanks.
It is easy to overlook or forget that full production hinges on more than just the operation of the kilns/processors. It is fascinating to watch the ideas tried and steps taken to refine the overall process. The bins look like they offer several handling, storage and transporting advantages. I would expect we will see this kind of operational adjustment for some time to come.
