You will struggle to do them in one go as the outside of the bean will dry and the beans get to temperature it shuts off then cools then you put beans in the shed and they get wetter on the meter moisture meters give false readings especially non grinding onesAnyone got an air temp/finishing temp for spring beans please, cut yesterday, bit tough so expect nearer 20% than 16%mc.
Haven't dried any for years, but would rather do job in one pass if possible.
