The thing ran about 110 degrees,those are solar panels.Drying took about 22 hrs.This year I need 50 times the capicity.I will be using condensors and running hot water through them to get the temps up to 140 degrees and dry in 10 hrs. Next year I will heat the water in a boiler powered by wood pellets made from my apple prunings.I will be able to use the same pelletizer for hops and wood pellets just a different set of dies.I would have it this year but its 75k
