after 16 hours of running the herbs did not dry evenly. This is actually an area of concern this is common for cabinet dryers. I originally planned to install a dynamic air deflector operated by the incoming air stream to get even air flow, since. But since the inspiration did not come on time and I have ran out of herbs I decided to go for the test. bad decision. I will say the
dryer is a failure for now. the burner though saves the day. I
think the burner itself will pay off more than the
dryer itself. another advantage of this gasifier over the usual BLDD and TLUD is the more stable heat all through out. The BLDD and TLUD requires more pressure from the fan since it has to push the air all through out the gasifier. As the fuel burn and the file of fuel becomes thinner the fire increases. There is also a need to insulate the whole gasifier as the fire runs bottom up or up to bottom. This partial draft gasifier gives even heat all through out and there is no need to insulate the whole gasifier. More over I can make the fuel storage as tall as I wanted so I can
feed the exact amount of fuel for the duration of drying. I think the loop pass with dynamic air deflector is the way to go.
anyone have an idea to save this baby ....
