[permaculture-oceania] Bulk Drying

[Rob W.]

Does anyone know about solar drying technologies for bulk products.

"I remember reading somewhere - I believe in a permaculture magazine - about 
someone who had built solar drying rooms, I think they used a gas or other 
heat source backup for when the temperature dropped below the critical 
point,  I think the application was for timber drying.

Our own application is for drying a hemp plastic that we will be making in 
Mullumbimby (northern NSW). www.zelfoaustralia.com, we'd love an alternative 
to using electricity (which of course would be green-power if we have to go 
that route)."

G'day Mitra, try http://www.fluidynenz.250x.com/ and look under Power 
Generation In The Hills.
It describes a wood fired power generator that utilises waste heat to dry 
timber
