So I was looking online for a solar dehydrator when I came upon this and thought that it was pretty cool. The step by step build is located at instructables dot com.
Sunlight gives you a little more than 200 BTUs/sq. ft. of heat.
My suggestion would be if you are going to build something similar:
1. The front of the yellow box should be aluminum foiled to bounce light down to the collector.
2. Add side wings with reflectors to the right and left of the collector.
You will be getting more than twice the heat with very little investment in material. It is important to have high heat to dehydrate, At low heat, you will be making a fermenting box instead. If your food is not dehydrate in one day, what are you going to do with the food?
I would like to look at the plans.
Would you mind sending those plans to me also? I have been thinking about building one of those for some time.
That's a great simple design. I think I have enough stuff laying around to throw together a one screen dryer just for fun. When I have time I'll have to read the rest of the book. Thanks again.
Though a bit cost prohibitive unless you just happen to have a job site nearby with some scrap.
Oops I thought you said ThinWall not Twinwall. Just specified ThinWall on a project here. Yes Twin wall is great for greenhouse and solar applications.
