Humid Climate Solar Dehydrator



This dehydrator is my version of an upper Mid-west design. I adapted it (as recommended) to fit the windows I had on hand, which I also use for my cold-frames. These windows were roughly 32" by 32", which matched nicely with 32" wide galvanized roofing. I couldn't get the wavy kind in my area, only the ribbed, so had to adapt the screen support system accordingly. I used cedar throughout for to withstand weather without coating it with any preservatives or paint. It also makes the frames really light so I can put them on a 4 1/2 foot high shed roof. Materials (for two dehydrators): 3 1x6 3/4" 6-foot cedar boards (these are fencing boards in my area - I picked for few knots) 1 sheet of 8-foot galvanized ribbed roofing (is enough for 3 dehydrators) 2 yards of 36" aluminum flashing 2 32" x 32" storm windows (or other similar sized glass) Matte black spray paint 2 yards of 36" aluminum screen Staples Galvanized nails (1 1/2") 1" finishing nails for drying screens Tools: Jigsaw with metal-cutting blade Tin snips Table saw with rip fence to produce frame elements Stapler

step 1The dehydrator in pieces

These are the components of the dehydrator: 1. Glass -- I used the framed pieces from a storm door. This determines the dimensions of your dehydrator. If your glass is …

step 2Constructing the frame

1. Measure your glass. The outside dimensions of the frame must match the edges of your glass. These directions assume that the north and south sides (N/S) have the same …

step 3Making the "heater"

The heater fits loosely inside the frame (including the braces). The drying screens will have a 3/4" frame, must clear the braces (if you are using them), and the heater …

step 4Make the screens

The screens are constructed of 3/4" cedar and aluminum screening. I made two for each dehydrator so that I could dry two different things at once without them mixing and …

step 5Assemble the dryer for use.

The dryer goes together easily. If I'm carrying it anywhere, I carry the glass separately. Everything else is light enough to sit in the frame. To load the dehydrator…
