Free, Green, Solar Dehydrator
Intro: Free, Green, Solar Dehydrator
Why Dry: Preserve fresh fruit/vegetables/meat/fish/prepared food that is surplus to current needs, and increase calorie density (reduce weight for transporting, backpacking, camping).
Why Solar/Green: Reduce carbon footprint
Why Free: Costco Kirkland Disney animal cracker container too nice to discard.
Other leftovers used:
- 30" of molding, mine was about 3/4" square
- 7.5" x 18.5" piece of window screen
- 4" diameter piece of window screen
- glue, staples
- (4) nuts and bolts, mine were 2"
- scrap lumber, my pieces were 40" of 1/2"x3" and 5" of 1 1/4" x 1 1/4" recycled plastic.
Tools used:
- hand saw, scissors, utility knife, tape measure, hand drill

STEPS:
STEP 1: Remove Bottom
1 - Cut out bottom of animal cracker container.
STEP 2: Frame Pieces
2 - Cut frame sides, my inside dimension was 6 5/8" square, I cut off corners so it would sit lower in the container.
STEP 3: Assemble Frame
3 - Assemble frame, gluing seemed easier than nails or screws.
STEP 4: Stand
4 - Attach container to stand. Bottom of container should be elevated to allow free entry of dry air.
STEP 5: Attach Screen
5 - Staple screen to frame. I placed some staples across frame joints to add mechanical hold to glue joints. Screen wraps all away around so top screen supports product and bottom screen keeps insects away.
STEP 6: Modify Cover
6 - Ventilate cover with holes and screen.
STEP 7: Place Frame in Container
7 - Place screened frame in container.
STEP 8: Dehydrate
8 - Place food in screen.
9 - Place dehydrator in sun.

I don't want to spoil your invention, but did you know that when it is heated, plastic becomes toxic? It would be better if the container were made of glass.

yes, it's scary to use plastic under the sun. it becomes toxic

I'm not sure but maybe plastic canvas screen from a craft or hobby store would be preferable over window screen. I like this little portable dehydrator. Thanks for sharing.

Combine with karalalala Granola Bars recipe !
Could add an ant killing strip where the solar container is hung to prevent intruders
I agree, glass seems better but might as well reuse these plastic containers as we head into the post-petroleum age!

My plastic dehydrator has open bottom and top, so it works like a chimney bringing in fresh air from bottom as air warms.
Let me know how you progress.

But if you live in an aggressive-ant area and they're not bothering with it, I'm interested in trying it out. I happen to have a half-full one of those Disney Costco cookie containers!

We have big ants and little ants. My dehydrator hangs from the patio roof and the ants haven't found it yet.
Try it....lyle

Thanks for the comment. Shelf life depends on moisture. So far I haven't been able to get too dry as the product has been lost to taste testing. Pineapple and banana dried one day tastes good, but it will probably take 4 or 5 days to extend shelf life to months. I'm hoping to eventually get to about 12% moisture.
Two to 3% goal mentioned in following link is probably not possible here in Hawaii.
