After 3 days of hard work, 2 calloused fingers, and a few cuts, I've finally finished (almost) our solar dryer. All we need now is the glass to cover the "hot air harvester" - more about this later.
Here it is!!!
From this angle you can see the exhaust at the top and the air intake at the bottom. At the back is the door.
This is where hot air exits. We'll be installing a fine meshed screen at the vent to avoid insects or other foreign objects from getting in.
I haven't made trays yet, but hanging bunches of leaves/herbs would work just fine.
This is the "hot air harvester" that i was talking about. The black part is made of GI (galvanized iron) metal sheet painted with black. The reason why its black is because black absorbs heat better. A glass sheet will cover the top part of the "hot air harvester" leaving about 4 inches of space in between the metal sheet. The bottom of the harvester will be left open so air can enter. Then the air will be warmed up by the metal sheet. Since hot air rises, it will enter our dryer and pass through whatever we place in there and exits through the vent. Herbs, fruits, meat, fish, are just a few examples.
We'll be posting more pics of our dryer in action soon after the paint cures.
I hope you got the idea on how this solar dryer works. If you have questions, feel free to post it at the comments section below or send us an email.
