The all new all recycled solar dehydrator!!! |
It looks like a cross between a children's slide, a rocket launcher and an outside shower. A big welcome to the solar dehydrator that we just built from all recycled materials based on the very informative videos on
permies.com. Its for drying all the fruit which is coming thick and fast this time of year.
The dehydrator works in a counter-intuitive way. The sun facing, glass fronted solar collector heats the air and it rises up the sealed black gutters into the top of the box. Then the air becomes humidified and drops to the base of the box. While this is happening the mat-black chimney which enters at the base of the sealed box heats up in the sun and also makes the air rise; effectively sucking it out of the bottom of the box. So air rushes over the thinly sliced fruit and dries it out!
Well, thats the theory! Its night time now so, sorry, can't test it yet. Plus, as the more astute of you will have noticed the door isn't on the back yet.... But when we were building it the metal at the back of the ramps and the chimney were getting hot in the sun. The minstrel insists that we put an insect blocker on each end to prevent invasion and the Captain wants it sealed from the inside. As for me, I think insulating the ramps will make it work even better.... and of course a gutter to collect rain caught on the roof and glass...
All I can say now is, watch this space!!!
