Okay to can dry beans?
Good question! Effective pressure canning and heat penetration is very highly dependent on the density and moisture content of the food. For these reasons, there is a soaking/cooking process of dried beans that is required prior to pressure canning. (It would be way easier to throw them in a can with some water, but it just won't work.)
Here are the recommendations from OSU Extension to prepare and pressure can your dried beans: https://extension.oregonstate.edu/sites/default/files/documents/8836/sp50955driedbeans.pdf
Best of luck with your processing!
