Left side tapering plenum contains downward blowing stove hood fan and heating element from toaster oven . Warmed air blows across 6 16 by 16 trays that are separated by upward sloping steel flashing baffles . Air is forced up through each tray and exits on right into upward expanding air exit. No moist air touches any other food. 1/4 inch through rods support flashing on the front and back .trays sit on top of flashing on right and bolts on the left side above baffle. Case was made from bits and pieces and could be made from washer /dryer/stove cases. I have made several much larger ones from insulated garage door panels . Have also used simple solar collector for heat.
