The process of dehydrating food has been utilized for years. Implementing “solar” dehydration is essentially just using the sun's energy to make it more “green” and “earth friendly” and eliminates the need for electricity.

How to Build a Dehydrator

Build the Heat Collector Box First

• The box should lined with a black plastic sheet or painted black; however, petroleum based paints should not be used as the fumes will affect your food.
• Holes should be made at the bottom front of the collector to allow for air ventilation (filters should be placed on the inside to keep out pests and other debris).
• The bottom and sides can be covered with Styrofoam or others types of insulation to increase heat efficiency.

Build Dehydrator Box Second

• Construct a box out of plywood with vents at the bottom front to receive the heated air from the heat collector.
• Line the dehydrator box with aluminum foil or other reflective material.
• Ensure trays are at least five inches shorter than the container so air can circulate completely around the food trays.
• Each individual tray should be made of plywood pieces and food-safe screens.

We're thankful for the guys at Off Grid News who took the time to put these items together. Being able to have sustainable food that actually tastes good without needing to use electricity is something everyone should learn about.
