A farmer's daughter and sister here - will that do? We regularly grew Field Beans which look like broad beans on the family farm.
They are harvested when they are dried, the pods blacken naturally and begin to shrivel - yes they do look burnt, but they're not. The pods turn black as they dry.
They will soon be harvested with the combine harvester - the dried beans will go through a series of riddlers (shaking sieves) in the combine harvester to separate them from the bits of pod, stalk and leaf (haulms).
The dried Field Beans go to the millers to be ground down to a flour and added to animal feed - they are high in protein. The haulms are usually baled and they go for winter stock feed a bit like hay. My herd of dairy goats ate a lot of bean straw in the winter as they need a lot of roughage.
