We've grown dry beans a few times, though never in much quantity, mostly just for our own family. They're a great crop in a number of ways - as a nitrogen-fixing legume they're good for the soil, they don't require a whole lot of work between planting and harvesting, and, once processed, they produce a great and somewhat unusual product that stores well and doesn't take up too much room. The tricky part is that little phrase, "once processed."
The bean plants need to be pulled and the pods dried down thoroughly so that the beans don't rot or sprout. Then the beans themselves need to be separated from their pods (known as threshing), cleaned of dirt and pieces of plant, and checked over for quality. On a household scale, we would just keep a bushel basket of pods handy and shell beans by hand whenever we watched movies or as we were sitting around the kitchen table after dinner. We mostly managed to keep up with our own bean usage that way, but it's not a particularly viable method on a commercial scale. Of course, there are plenty of machines one can buy to thresh and clean beans, but those are also typically not viable on the relatively small commercial scale at which we are operating.
There are a number of small-scale solutions, powered by bikes or made from modified wood chippers. There are also extremely low-tech solutions, like putting the beans in an old pillowcase and whacking it against a hard surface until the beans fall out of their shells, and then pouring it all in front of a fan a few times to blow away debris. That will probably be our solution for a few batches of beans until we figure out which kind of slightly higher-tech solution will work best for us.
Look for dry beans at the market in a few weeks and in CSA pretty soon!
