One afternoon my wife and daughter were going to see the latest twilight movie and asked if I wanted to go. I politely declined. So after they had left to head to the theater I was getting a little bored so I decided to build a solar dehydrator.

I went down to the hardware store and picked up some materials

I cut some 2x4's down to 2 and 4 foot pieces

and screwed them together to form a framework

I had picked up some 2x2 sheets of aluminum and 2x4 sheets of luan. I test fitted the luan onto my frame

and screwed the aluminum onto the frame

I backed it with the piece of luan

I grabbed my 1 inch wood bit and drilled out vent holes in the top and bottom of the frame

5775171605_5d59bac940_z.jpg

I spray painted the whole thing flat black

5775173483_0a9c99cd14_z.jpg

I had picked up a 2x4 sheet of lexan. I laid it on top of the frame and pre-drilled mounting holes

5775716028_fdc52575a5_z.jpg

and screwed it down to the frame

5775176437_054f147727_z.jpg

I set up my thermocouple to check the temp and it was climbing

5775719944_63497617fb_z.jpg

I let it sit in the sun a little longer to see what I could get the temp to

5775720952_a6b31679b4_z.jpg

and was able to get it to 123 after about 15 minutes

5775180073_733a6806dd_z.jpg

I grabbed some more 2x4's to make the frame for the dehydrating chamber

5775181163_b866f3f39e_z.jpg

and stood the panel up into the frame to test the angle

5775182073_81914a2365_z.jpg

and was able to get the temp up to 136

5775182955_bf1fe8ab64_z.jpg

so I took the lexan panel off

5775184065_57beb5c819_z.jpg

and mounted some netting across the bottom holes to keep bugs out of the chamber

5775186971_c078289499_z.jpg

I used some soda cans I had and placed them into the chamber to increase surface area for creating heat

5775187801_d958ae1f71_z.jpg

I used the scraps from my whole saw to block up the cans so they didn't interfere with air flow

5775730226_57ab63e8ef_z.jpg

and spray painted the whole thing black

5775731480_0e8cef657d_z.jpg

I used the netting to hold the cans in place

I trimmed off the excess netting and ran a bead of silicone around the frame

5775192435_55654e7451_z.jpg

and remounted the lexan, I overtightened the screw in the top right corner and cracked it, awesome

5775734750_dbb6c08475_z.jpg

I continued building the frame for the chamber

5775735430_b5660f4bfc_z.jpg

and screwed down a scrap piece of luan for the base

5775195013_7e2e9f68c0_z.jpg

I did another temp test

5778843682_9172f1acff_z.jpg

and was able to draw 152 degrees

I used a piece of scrap wood to establish spacing for the tray holders

5778848574_f9ea30f5b0_z.jpg

and screwed down a scrap piece of 1x material

5778849596_1f660da590_z.jpg

and continued screwing them down

5780463897_aa5938d595_z.jpg

5781014886_4a754bef5d_z.jpg

I picked up a vent for the roof

5780465579_3b8094e635_z.jpg

and spray painted it black to help with draft
