Introduction: Solar Dehydrator
A solar food dhydrator removes mostiure from food to ensure proper preservation. It uses heat and air flow to reduce the water content in food. This process prevents bacteria from growing and ruining food.
All materials were reused from various sources, but can be cheaply purchased if you don't already have access to them.
Step 1: Materials
2x 22 inch 2x4
2x 16 inch 2x4
18"x11" window (glass or plastic)
Dark stretchable material.
Step 2: Platform & Base
Take the 2x4's and build a square platform with the 22" on the outside and the 16" on the inside.
Next staple the screen onto the platform.
Cut a piece of plywood measuring 19"x19" with 6"x3" cuts in the corners for ventilation. Then attach the plywood to the bottom of the platform.
Step 3: Sides Panels
Cut 2 pieces of plywood into 22"x16" with a 45 degree diagonal cut.
Then nail the sides to the platform.
Step 4: Front Window
Using 1x4 cut 2 pieces into 22 inch length.
Then cut the 1x3 into 16 inch length.
Cut a 45 degree angle into each end and then nail all four pieces together.
After the frame is completed caulk the window onto the frame.
Step 5: Interior Shelf
Cut two pieces of 1x2 into 21 1/2"
Cut two more pieces of 1x2 into 11"
Nail the ends together.
Wrap a dark stretchable fabric around the frame. This will be the shelf that your food rest on.
Next cut 2 pieces of 1x1 into 1', and then nail them onto the interior side panels 8 inches from the bottom. This is where the shelf will sit.
Step 6: Top & Back Panel
Cut a piece of plywood measuring 22''x9 1/2".
Next, cut 2 pieces of 1x2 9 1/x2" and one piece 20" long. Then nail the 1x2 to the 9 1/2" sides of the plywood, and the 20" to the back of the piece.
Then nail the top panel to the two side panels.
Cut another piece of plywood measuring 20x12. Attach the hinges to the bottom platform. After it is attached the back panel will easily squeeze into the side walls and top.
Step 7: Completed
After it is completed you will have an energy efficient way of drying and enjoying your favorite fruits and other snacks. Dehydration will take place between 100 to 140 degrees f. It will vary for different types of food so be sure to research and find the best result. You can regulate the temperature using the vents on the bottom and the back door. Enjoy and have fun!
