As a soybean farmer, and one who has focused on IP soybeans for the human market for most of my career at that, unless I am misunderstanding you, that is exactly how we do it. The beans are harvested dry, packaged, stored, and then shipped (primarily) to the Asian markets who are interested in such product.

The trouble in North America is that few know what to do with them. To be honest, I have never even tried my own product. I also grow navy beans and have cooked with them. They are more of a common staple in these parts. But they are also a much more fickle crop. You're not going to easily replace soys with other edible beans.
